Not everything is rocket science, but some scientific concepts might be harder to understand than others. If someone stopped me on the street and asked how mirrors work, for example, I wouldn't know where to begin. Sometimes, we need someone to explain things to us in simple, layman's terms.
The Explain Like I'm Five page does just that, as it breaks down complex concepts with language that even a child would understand.

How do you all deal with the ads on BP?

In 1960, David Latimer planted a spiderwort sprout inside of a large glass jar, added a quarter pint of water, and then sealed it shut. He opened the bottle for the first time only 12 years later, in 1972, to add some water and then sealed it for good. The self-contained ecosystem flourished for more than 60 years as a perfectly balanced garden and self-sufficient ecosystem. The bacteria in the compost ate the dead plants and broke down the oxygen released, turning it into carbon dioxide, essentially forming a microcosm of Earth
Not _fully_ self-sustaining: it needs ongoing input of solar energy. (But still very impressive!)
Did this in 6th grade (1972). Isn't science class any fun anymore?
It's a shame we won't do that with the Earth. At least not enough of us.
Starlings see each other using their exceptional ultraviolet (UV) vision, which allows them to perceive colors beyond what humans can see, meaning they likely see each other with enhanced markings and colors due to the way their feathers reflect UV light, giving them a different visual appearance compared to how we see them; essentially, they can see more detail and distinction between individuals in a flock than we can
Humans are infrared and ultraviolet deficient. We have stripes and are bioluminescent. Birds can probably see them, mammals likely can’t
Load More Replies...We'll never see them in UV (pr IF) but in the right light they look far less drab than most people probably think they do.
Simplified further with some additional information that you might not know yet if you need it simplified this much: We see colors because the colored light reflects off of an object and our eyes have sensors called cones to pick up those colors! There are colors that we can't see, but birds can because their eyes have more cones! Look at this bird. To us, it's really pretty, isn't it? But to a bird, there might be more colors and markings and maybe it's even prettier!
One of the scariest stories I read as a kid was about an animal that was invisible and offing humans. The explanation for why humans couldn't see the animal is that humans see limited wavelengths and the animal was outside of that. My child brain took that explanation hook line and sinker. The problem I didn't realize is that not bending rays of light in the visible spectrum is basically impossible, it had nothing to do with human sight.

The ELi5 Instagram page is fairly new, created only a year ago in February 2024. Yet it still has quite an impressive following of 518k. We could attribute it to people's love of learning new things; after all, 87% of American internet users do say that the World Wide Web has improved their ability to learn new things.
The concept of "Explain it to me like I'm 5" isn't new either. The Reddit community of the same name has over 23 million members. The internet is peppered with similar online groups, podcasts, and YouTube shows. We love learning new things when they're communicated in a simple, easy-to-understand language.
Researchers have developed a technique that involves gluing two proteins together to encourage cancer cells to self-destruct. This innovative approach, known as “protein degradation,” uses a type of molecule called a PROTAC (proteolysis-targeting chimeras) to bind a disease-causing protein to another protein that tags it for destruction.
Essentially, it reprograms the cell’s machinery to remove harmful proteins selectively, triggering cancer cells to destroy themselves while sparing healthy cells. This technique is still being refined, but it represents a promising strategy for targeted cancer therapy, especially for cancers resistant to conventional treatments. 📸- Ella Maru Studio/ Stanford Medicene
Self-destruct isn't the term I would use, as that is a cell's way of killing itself if there is an error. It hijacks the ubiquitin pathway, the cell's way to mark proteins for degredation, and activates an enzyme that pulls apart any protein with this marking. Self-destructing is what the cell can't do, this modifies the cell to effectively cut itself to pieces.

Load More Replies...KAIST researchers, led by Professor Kwang-Hyun Cho, have introduced a revolutionary approach to treating colon cancer by reprogramming cancer cells into a normal-like state instead of destroying them. Traditional cancer treatments aim to eliminate cancer cells, but they often lead to resistance, recurrence, and severe side effects due to damage to healthy cells. This new method offers a promising alternative by addressing cancer without causing harm to surrounding tissues.
The research team focused on the concept that during cancer development, normal cells regress along their differentiation pathway. To better understand this process, they developed a digital twin model of the gene network that controls normal cell differentiation. Through simulation analysis, they identified key molecular switches capable of pushing cancer cells back into a normal-like state. When applied to colon cancer cells, these switches successfully reversed their malignant characteristics, a breakthrough confirmed through molecular experiments and animal studies.
This study highlights the potential for "reversible cancer therapy," a novel concept where cancer cells can be reprogrammed rather than eradicated. Unlike conventional treatments that rely on trial-and-error drug discoveries, this approach systematically identifies key targets using computational models. The findings suggest that similar techniques could be applied to other types of cancer, opening new avenues for safer and more effective treatments.
The study, co-authored by Jeong-Ryeol Gong, Chun-Kyung Lee, Hoon-Min Kim, Juhee Kim, and Jaeog Jeon, was published in Advanced Science on December 11.

This does seem like a better method. Cancer is caused by the biological equivalent of a data error, fixing that error is far less damaging and far more likely to have a lasting effect.
It depends on the stage. During stage 1 I agree, but when those nasty cells start travelling, you want to kill them if possible. That is something another company tries and now there are clinical tests where we have one report of destroying metastases in other body parts. If this is confirmed on more cases (it could be just a fluke you know), it would be amazing tool for oncology.

A 9,000-year-old skeleton, nicknamed Cheddar Man, was discovered in Gough's Cave in Cheddar, England. This ancient skeleton, one of the oldest ever found in Britain, has provided a fascinating glimpse into early human history. DNA analysis revealed that Cheddar Man had dark skin, blue eyes, and dark, curly hair, challenging previous assumptions about the appearance of early Europeans. Even more astonishing, scientists found a living relative of Cheddar Man residing just half a mile away, tracing the lineage back nearly 300 generations. This discovery underscores the deep ancestral connections between ancient populations and modern-day descendants, highlighting the continuity of human history in specific geographic regions

Pigeons have a rich history intertwined with human civilization, and their nesting behavior has roots in their ancestral past. The rock pigeon (Columba livia), from which most modern domestic and feral pigeons descend, originally nested in cliffs and rocky crevices in the wild. These environments required minimal nesting materials, as the natural terrain provided protection and support for eggs and chicks.
As humans began to domesticate pigeons thousands of years ago, their nesting habits adapted to artificial environments like rooftops, buildings, and ledges that mimicked their natural cliffside habitats. Ancient civilizations, such as those in Mesopotamia, Egypt, and Rome, raised pigeons for food, messages, and religious purposes, providing them with simple nesting spaces like dovecotes.
Over time, pigeons became less dependent on elaborate nest-building because human-provided shelters offered protection and reduced the need for sturdy nests. This historical reliance on natural and artificial shelters influenced their present-day nesting behavior, resulting in the minimalistic and "lazy" nests pigeons are known for today
I read this to my 5 yo and can report she needed it even more simplified. "Humans built nests for pigeons so long that they forgot how to do that. That is why you have to clean your room, if I do it you may forget how" She dissaproves and thinks pigeons has a better life then her.
The last paragraph contradicts the first yanno. Pigeons are domesticated rock doves, and they build nests on cliffs that don't require much in building materials - they didn't build "sturdy nests" to begin with. Wild rock dove and feral pigeon nests can and do look the same, depending on what surface they are trying to lay on.
It would be the pigeons world. We’d be the ones carrying messages. 😬

Brazil’s mysterious tunnels, known as paleoburrows, are massive underground structures found predominantly in the southern and southeastern regions of the country. These fascinating formations are believed to have been dug thousands of years ago by extinct giant ground sloths, some of which were the size of modern-day elephants.
Professor Heinrich Frank, a geologist from the Federal University of Rio Grande do Sul, first encountered these tunnels during an expedition and was immediately struck by their sheer scale and the distinct claw marks etched into their walls, undeniable evidence of ancient megafauna activity. Frank’s research revealed that some of these tunnels stretch over 600 meters, with diameters wide enough to walk through.
He suggests that these burrows were likely created as shelters or protective spaces, though their exact purpose remains a mystery. Frank’s expeditions have also shed light on how these extinct creatures shaped their environment, showcasing their engineering capabilities. These paleoburrows provide a unique window into prehistoric ecosystems and underscore the significant role these massive creatures played in altering their habitats
I didn't know they dug tunnels. More like caves. There's a giant sloth skeleton replica in The Manitoba Museum. Giant-Preh...47d613.jpg

Although we call it "Explain it like I'm 5", we don't necessarily want things explained to us like we're literally five years old.

Third Man Syndrome is a curious psychological phenomenon where people in extreme, life-threatening situations, such as explorers, mountaineers, or disaster survivors, feel the presence of an invisible companion. This "third man" is often perceived as a calm, comforting figure who provides guidance, encouragement, and a sense of safety, even though no one is actually there. It’s not just a vague feeling; many describe this presence as real, almost like a guardian angel helping them through a critical moment.
Imagine you're lost in the middle of a desert, exhausted and close to giving up. Suddenly, it feels like someone is walking alongside you, quietly encouraging you to keep moving, guiding your steps, even though you know you're physically alone. It’s as if your mind, under extreme stress, creates this "companion" to help you survive, similar to how we sometimes talk to ourselves for reassurance during tough times. In moments of intense fear or danger, the brain can conjure this supportive figure to help push through and keep going when survival feels impossible. It's the mind's way of creating a psychological lifeline when you need it most

They landed on the island they were aiming for - after an incredible feat of navigation - but the settlement was on the other side so they basically had to climb a mountain after a gruelling sea voyage with minimal provisions. The unseen presence (in this case I think it would have been a fourth man) helped them make that final push to find help.

A study led by UCL and the Anna Freud Centre used fMRI scans to investigate the impact of family violence on children's brain activity. The research revealed that children exposed to domestic violence show heightened activation in the anterior insula and amygdala - regions associated with threat detection and anxiety - when viewing angry faces.
This neural response mirrors the brain activity found in soldiers exposed to combat, suggesting that both groups may become "hyper-aware" of danger due to their environments. These changes in brain functioning, although potentially adaptive in the short term, may increase the risk of developing anxiety disorders later in life.
Dr. Eamon McCrory, lead author, notes that while none of the children studied had mental health issues at the time, their altered brain function could indicate an underlying risk factor. Professor Peter Fonagy, Chief Executive of the Anna Freud Centre, highlighted the importance of this research in raising awareness of the lasting impact of violence on children's brain development and in guiding clinical and social work practices.
The findings underscore the need for continued efforts to protect children from violence and to develop effective treatment strategies. The next research steps include investigating how stable these brain changes are and understanding the resilience mechanisms that help some children overcome early adversity
As someone who grew up with family violence and thought it was normal, I wish I could do more to help other vulnerable children in this world. If anyone young is reading this and is in a vulnerable situation, just remember to get as much out of your education or vocational training opportunity as you can and hopefully it will be your passport to a better life.
Same. I got involved so much in cases of vulnerable children (sick, impoverished, victims of abuse). It felt good when I could really help someone, but most of the time it was exhausting. 😟 I needed years of therapy to understand that this was a trauma response.

In 2016, a groundbreaking discovery revealed a 99-million-year-old dinosaur tail perfectly preserved in amber. Likely belonging to a juvenile coelurosaur, this specimen offers an exceptional glimpse into the Cretaceous period, showcasing not only bones but also feathers.
The preservation of feathers in such detail allows scientists to study their structure and color like never before. Amber preserved delicate features that would have otherwise decayed in traditional fossils, including the fine arrangement of feathers resembling those of modern birds.
This discovery provides valuable insights into the evolution of feathers, shedding light on their roles in thermoregulation, display, or flight. Along with the tail, plant debris and a Cretaceous-era ant were also preserved, offering a rare snapshot of the ecosystem from that time.

Basically, when you are standing, blood flow slows and "pools" in your legs due to gravity. But when you walk, your muscles contract and push the blood in your veins and vessels back up into your upper body.
On the side note, seasoned military personnels are able to stand at ease for long periods of time because they are actually swaying back and forth very slowly in micro-movements to contract their muscles and relieve the tingling and numb sensation you get when you keep standing for long periods of time.

In certain forests, when you look up you will see a network of cracks formed by gaps between the outermost edges of the tree branches. It looks like a precisely engineered jigsaw puzzle, each branch growing just perfectly so it almost - but not quite - touches the neighboring tree. This beautiful phenomenon is called crown shyness. Crown shyness doesn’t happen all the time, and scientists aren’t completely certain why it happens at all. There is some evidence that it most commonly occurs with similarly aged trees, especially stands of the same species. But it can occur in any forest
The reason that it is never good to 'top' a tree is that a hormone produced by the trunk is what makes it a trunk and not a branch; when the tree is topped the next set of branches are not suppressed so they each think they are the trunk and they each grow as if they were
So THAT is why I'm supposed to 'top' my houseplant! Imma trick some branches into thinking they're the trunks! Ha!

An armadillo's armor is much more than just tough skin; it is actually a separate bone structure that sits on top of their skeleton. This bony shell acts like a natural armor, protecting the armadillo from predators. The structure is made of bony plates, known as "scutes," that are attached to the armadillo’s body, providing both strength and flexibility to move. This unique feature helps armadillos survive in the wild, allowing them to roll up into a ball for extra protection against threats. It's an incredible adaptation for defense!

A man in TX once shot an armadillo and the bullet bounced off and hit him. back and hit him.
Armadillos can curl up but only ONE can turn into a ball and that is the 3 banded armadillo from south America. it can completely tuck its self into a ball with its head plat and tail finishing it off. this is because jaguars are one of the predators who eat them and this helps to protect them. However the big cats have learned that if there is a body of water around they can bat the armadillo ball into the water and wait for it to open up to save its self from drowning then eat it... Anyway none of the other armadillos can do more than curl up into a tight U shape
Turtle shells, on the other hand, are fused ribs. A mystery of evolution is what inspired the shoulder blades to migrate into the rib cage.

Lagoons of water found in Sahara Desert after 50 years of being dry
Recently, parts of the Sahara Desert, especially in Morocco, experienced unusual rainfall after 50 years of dryness. This rare event caused lagoons of water to appear in regions that had been dry for decades.
The rainfall was triggered by a combination of factors, including the northward shift of the Intertropical Convergence Zone (ITCZ), which typically stays closer to the equator. Warm ocean waters, converging winds, and strong sunlight created the perfect conditions for this significant rainfall.
In places like Tagounite, more than a third of the annual average rainfall fell in just 24 hours. The heavy rain filled dried lake beds and desert areas, creating temporary pools and rivers that haven't been seen for years.
Scientists suggest that climate change and shifts in atmospheric patterns may have contributed to this anomaly. The rains are helping replenish groundwater sources, but also caused floods and damage in rural areas
That's a really big change for the desert and could bring exciting new growth.
Unfortunately, this change is not limited to the Sahara. E.g. we in the Netherlands are getting soaked, and there is already plenty of water we need to keep under control to survive. Farmers experienced severe problems, because first the fields were too wet to sow/plant anything, and later the harvest either drowned or couldn't be harvested because the fields were unaccessible. Climate is like a too small blanket.

If you are lucky enough to survive a lightning strike, in addition to the physical and psychological consequences, you will see a kind of tree or root-shaped tattoo on your body: lightning flowers. These are generated when a body that does not conduct electricity receives a high electric charge. Lightning flowers, also known as Lichtenberg figures, are produced when the capillary vessels under the skin break due to the lightning discharge.
The appearance or shape we see would mark the path and degree of absorption of the lightning. These natural “tattoos” do not last a lifetime, they only appear for a few hours or days until they disappear completely. It should be noted that these figures can also appear in places where lightning strikes.
Although it is not very common, there are occasions in which they have been observed in grassy areas where lightning has struck, such as golf courses or soccer stadiums. These figures were discovered by the German scientist Georg Christoph Lichtenberg in 1977, after whom they are named. The so-called lightning flowers had such peculiar ramifications that they generated great interest and began to be studied. Nature is as beautiful as it is dangerous. That is why every precaution is too little when faced with natural phenomena such as a thunderstorm
Fortunately? I don't know, but having a cool scar is, well, cool, right? Some people like to show "this is where I was cut" or "this is bite mark from shark", so I think "this tree is the only thing I have after getting hit by a lightning" would be also pretty cool.

Load More Replies...Blood Falls is a strange and fascinating natural phenomenon in Antarctica where bright red water seeps out from a glacier, making it look like the ice is bleeding. It flows from the Taylor Glacier in the McMurdo Dry Valleys, one of the coldest and driest places on Earth. At first glance, it seems like the red color might be due to algae or some other living organisms, but the real reason is actually hidden deep below the glacier.
The science behind Blood Falls lies in its salty, iron-rich water. About 2 million years ago, a small body of water got trapped under the glacier, cut off from sunlight and oxygen. Over time, the water absorbed a lot of iron from the surrounding rocks. Because there's no oxygen, the iron stays dissolved in the water, just like iron in an old rusty pipe.
When the water finally escapes and reaches the surface, it comes into contact with oxygen in the air, causing the iron to oxidize and turn red, just like rust. This reaction is what gives Blood Falls its eerie, blood-like color. Despite the extreme conditions, scientists have also discovered tiny microbes living in the water, proving that life can exist even in some of the harshest places on Earth
This was a "mystery"? 500 years after learning that it's the iron in blood that makes it red? I'm so disillusioned about the value of a PhD degree now . . .

Why is 12-hour time even taught? Wouldn’t it just be easier to remember 13:00 instead of 1:00pm? 12 hour time is a very ancient system that traces back to the Mesopotamian empires. They had a cultural fixation on the number 12, used a base-12 numerical system, and divided up most things into 12ths whenever possible - including day and night.
The 12 hours of day and 12 hours of night system spread throughout Europe and the Middle East and has defied multiple attempts to change it over the centuries. Also for anyone curious why there was such a love of the number 12, it was because that was how they counted on their hand.
Look at your hand. Notice how each of your fingers minus your thumb has three easily identifiable parts to it. They used to count by using their thumb to count each part of the finger, much in the same way we count to 10 using our fingers today. So, 12 was the max you could count on one hand
In my country, we normally use 24-hour time, including for bus/train schedules.

Chinese culture counts the bend in the fingers too. Needs getting used to but means you can use the other hand to tally how many sets of 12... Can easily use fingers to count off 144
Load More Replies...The explanation is not entirely correct. The finger/joint counting is one theory, but the approximate twelve cycles of the moon per year and the subsequent 12 sign of the zodiac may also have been at the heart of it. 12 divides nicely into 60, as in minutes per hour, which may also have to do with five fingers of one hand counting the 12 joints of the other. Regardless of the origin, using base 12 and base 60 combined in this way allowed arithmetic to be done with very little need for irrational fractions.
We 12 and 12 users are just biding our time until metric clocks are introduced.

When helicopters operate in sandy environments, the downward thrust of their rotors kicks up clouds of sand. As the blades cut through, the hard sand erodes the abrasion-resistant titanium or nickel coatings, releasing fine metal particles. These fragments ignite due to heat and their pyrophoric nature, producing the fiery Kopp-Etchells Effect. The Kopp-Etchells Effect was named in honor of two soldiers, Benjamin S. Kopp (U.S. Army) and Joseph Etchells (U.K. Army), who died in Afghanistan in July 2009. The term was coined by Michael Yon, a former Green Beret and independent combat journalist 📸- Michael Yon/X
Because it's a shortcut, a simplified system created by scribes who had to write a lot by hand. So these scribes (some of them were monks) discovered that instead of raising the pen from the paper over and over again to write a new, separated letter, it was easier and faster to keep a continuous line that flows tying one letter to the next.
This system, called cursive, works great for some of the Latin letters, but not for most of them which had to be adapted. This is why A, B, E F, G, H, I, L, M, N, Q, R and sometimes S look very different in cursive from their uppercase versions.
This cursive system was later adapted by printers as the lowercase fonts.
Skill, not talent, and despite common belief, it is still taught in most school districts.
Load More Replies...And the word "lowercase" refers to the fact that typesetters kept the capital letters in an upper case, and the non-capital letters in a case that was lower than the one for the capital letters.
Anyone finding the latin alphabet confusing with its different upper and lower case forms should take a look at the Greek (Cyrillic) alphabet. Even bigger difference between upper and lower case there, probably for the same reason.
Greek Cyrillic isn't that bad, try Slavic Cyrillic...

There's no shame in admitting you don't understand complex scientific concepts and need them explained simply. Astrophysicist and science communicator extraordinaire Carl Sagan wrote in his 1994 book The Demon-Haunted World: Science as a Handle in the Dark about the importance of clearly communicating difficult subjects to the general public. "Don’t talk to the general audience as you would your scientific colleagues."
Dina Sanichar, often called the "real-life Mowgli," was a boy discovered in 1867 by hunters in the jungles of Uttar Pradesh, India. When found, he was living with a pack of wolves and behaving like one of them - walking on all fours, growling, and eating raw meat.
The hunters brought him to the Sikandra Mission Orphanage, where caretakers tried to help him adapt to human life. However, Dina never fully adjusted; he struggled with basic human skills like speaking, using utensils, or wearing clothes. Though he learned to walk upright and eat cooked food, he remained largely silent and withdrawn.
His story, along with accounts of other "feral children" found in the wild, is believed to have inspired Rudyard Kipling's famous character Mowgli in *The Jungle Book*, who was also raised by wolves. Dina’s life showcases the profound impact of early life experiences on human development and the challenges of reintegrating into society after living in the wild. His existence reflects the thin line between human and animal behavior and how environment shapes who we are
I want to know why his eyes are all bugged out. Even living out in the woods or living in a tribal situation or anything like that shouldn't make you a bug eyed bony mess. After all if that's how we fared in the wild we wouldn't have evolved this far.
He appears to be very thin. With less flesh, the eyes become more dominant. He is also holding an expression that is rather uncommon that likely exaggerates the effect.

I remembred reading about a experiment, not sure if it was a experiment, but where a young chlid maybe a toddler and a young chimpanzee were put together so the young boy could teach the chimpanzee human ways. Instead of what happened the young boy started to imitate the chimpanzee behavior. So they had to remove the boy from the chimpanzee and teach the boy human behavior.
Gnawing on bones doesn't sharpen your teeth. It wears them down. This whole story from more than 100 years ago sounds like a hoax
I believe the overall story but I don't get the part about how gnawing on bones sharpens teeth. Lots of chewing wears teeth down, it doesn't sharpen them. Chewing on hard things seems like it would just speed that up. The teeth of herbivores like cows and horses wear down over time. Once in a while I'd find a cow tooth in the feed trough. Rats chew on things to keep their teeth from growing too long. Try chewing on sand for a month - Spoiler - it won't make your teeth sharp.
"Gnawing on bones to sharpen the teeth"? No, person who doesn't understand human physiology. Gnawing on bones would dull the teeth. The story of this person being "raised by wolves" was made up. A human baby wouldn't have survived the first time an adult wolf would have tried to carry them for any distance. Also, wolf play would likely have caused wounds that would have been infected and would have killed the child.
Who says he was a “baby.” Maybe he was 2. Old enough to imitate behavior. There have been more than 1 report of feral children. All have trouble with speech and socialization. Although who knows what came first? Why would a parent abandon a child? Maybe they weren’t speaking or socializing well.

Most countries set their time zones in whole-hour increments, like UTC+5:00 or UTC+6:00, but Nepal is different because it uses a 45-minute offset instead of the usual 30-minute or 60-minute adjustments.
This unusual time setting dates back to 1956, when Nepal decided to base its official time on the longitude of Mount Gaurishankar (east of Kathmandu) instead of its capital. This led to the extra 15-minute shift from the more common UTC+5:30, which countries like India and Sri Lanka follow. The decision reflects Nepal’s independence in setting its own time rather than following its neighbors.
Because of this, Nepal stands out as one of the few places in the world with a 45-minute time zone offset, making it a unique feature in global timekeeping. This difference can sometimes cause confusion when setting clocks, scheduling flights, or adjusting digital devices. However, for Nepal, this small but significant difference symbolizes its sovereignty and national identity.
Just started working for a Nepalese company - I will impress them with my awareness of this factoid at a later date.
South Australia and Northern Territory are on a half hour offset because the timeline is in the middle of the Nullarbor Plain whereas most of the population is on the other side of the state.
Eating walnuts with breakfast could give your brain a natural boost that lasts all day. A recent study found that young adults who ate a handful of walnuts in the morning had quicker reaction times and improved memory throughout the day.
This is because walnuts contain brain-friendly nutrients like omega-3 fatty acids, antioxidants, and polyphenols, which help improve cognitive function. Unlike short-term stimulants like caffeine, walnuts support brain health in a more natural and lasting way. Adding them to your diet could enhance focus, learning, and mental performance over time.
So the best breakfast would be a thick skin onss salmon crusted in walnut
Unless of course u have a nut allergy then do not try this at home lol
The only downside is that although nuts contain healthy fats, they're high in calories, which is a bummer as I love eating them.
I think of walnuts as the pecan's cheaper but still good enough little cousin.

Armpit sweat glands are known as apocrine sweat glands, and instead of just sweat, they also produce a mix of proteins and lipids.
The bacteria on your skin love that stuff and eat it up, producing waste products in the process. It's those waste products that smell bad.
There is a variance in body odour depending on the presence of a mutation in the ABCC11 allele. It changes the size of the apocrine sweat glands, with the smaller size leading to less protein excretion, so the amount of the odour is reduced due to the presence of less protein-eating bacteria.
Too many people seem to think they have the mutated gene when they definitely don’t 😂

These scent glands are genetically tied, believe it or not, to ear wax. Oniony under arm smell is linked to liquid ear wax, whereas mild and less noticeable scents are linked to hard and chunky ear wax. The stinky combo is generally linked to Europeans, and the chunky comb is linked to Asians
Ulnar dimelia, also known as "Mirror Hand Syndrome," is an extremely rare congenital anomaly where the forearm and hand structures are duplicated symmetrically.
This condition is characterized by the absence of the radius bone, which is one of the two main bones in the forearm, and instead, there is a duplication of the ulna, the other forearm bone.
As a result, individuals with this condition typically have an abnormal number of fingers—usually seven or eight—without a functional thumb. This mirror-like duplication leads to a unique but non-functional hand structure, often requiring surgical intervention to improve functionality. While the exact cause of ulnar dimelia is not fully understood, it is believed to be linked to disruptions in early limb development during fetal growth.
Due to its rarity, cases of mirror hand syndrome provide valuable insights into limb formation and genetic regulation.

There was some concern that cell phones might interfere with communication by the pilots but that is proven to not be an issue.
However cell towers mainly point their antenna at the ground because that is where the people tend to be. When you are flying you will be changing cell tower zones very quickly and it will be very difficult for your cell phone to talk to them, if it can reach them at all.
As a result your phone will tend to crank up its transmitter to maximum power and basically scream into the void searching for a signal, burning battery power and producing as much radio noise as allowable. Since you know it won't work right it is best practice to turn on airplane mode so it won't do that.
Plus there is a marginal increase in the risk that if a battery problem in a phone was going to happen, thrashing it in such a manner might tend to kick it off right then.
Older frequencies from older phones could interfere with older plane electronics. But if your plane was made post 1996 and your phone in the last 15 years, there wont be an issue. In the early days of mass Cellphones it was an issue. Now its not. So its not "proven to not be an issue" but rather it isnt an issue anymore

Tokyo has seen an 84% decrease in suicides at train stations where blue LED lights were installed. First introduced in 2009 on the Yamanote line, these lights were part of a broader initiative to address the city’s high s*****e rates.
The calming effect of blue light on mood is thought to play a role, as well as the lights’ strategic positioning on platforms. Alongside the lights, Tokyo also implemented automatic gates and barriers on train platforms to deter attempts, as well as improved counseling services like the “Inochi no Denwa” hotline. Additional steps include government-funded programs aimed at reducing suicides by 20% from 2005 levels.
This includes investigating the root causes of s*****e and working to shift cultural attitudes. These interventions are costly, but they have contributed to a recent drop in s*****e rates, showing some progress in Tokyo’s ongoing efforts to address this complex issue. Source - nextcity.org
Yeah, no. Japan considers a d**g overdose as suicide. Under blue lights you can't find a vein to inject, so junkies are unable to shoot up there now.

The idea that carrots dramatically improve eyesight, especially night vision, is actually a myth that started during World War II. The British Royal Air Force spread this rumor to hide the real reason their pilots had improved night-fighting abilities—radar technology. They claimed that pilots ate a lot of carrots, which helped them see enemy planes better at night. This clever propaganda misled enemies and also popularized the idea that eating carrots could significantly boost vision.
However, while carrots don’t give you super eyesight, they do contain beta-carotene, a type of pigment that the body converts into vitamin A. Vitamin A is essential for eye health because it helps maintain the retina, particularly the part responsible for seeing in low light (the rod cells). A deficiency in vitamin A can lead to night blindness, but consuming more than the necessary amount doesn’t give you enhanced vision beyond normal.
So, while eating carrots can help prevent vision problems related to vitamin A deficiency, they won’t give you night-vision superpowers. The best way to keep your eyes healthy is a balanced diet with a variety of nutrients, not just relying on carrots!
As someone with extreme myopia, I was very disappointed when I learned this!

Wasn't it discovered that consuming bilberries was useful with night vision, or am I just seeing things ?
Did people actually believe carrots helped your eyesight? Did these same people really believe that masturbation would make you go blind?
Well, they can and do, but the actual carrot part has far too much sugar to be healthy for them. The carrot greens, however, are much healthier for them and can be part of their regular diet.
Load More Replies...A giant tadpole named Goliath was discovered with a hormonal imbalance that prevented it from transforming into a frog. Goliath was much larger than the average American bullfrog tadpole, making it a unique case for researchers to study. Normally, tadpoles undergo metamorphosis to become froglets, a process controlled by thyroid hormones thyroxine (T4) and triiodothyronine (T3). However, when there is a hormonal imbalance, this transformation can be disrupted.
If a tadpole lacks the gene that produces thyroxine, it cannot metamorphose into a frog. In some cases, developmental hormones may be turned off or reduced, while growth hormones may be excessively active, leading to abnormal size without proper development. Unfortunately, Goliath died in 2019, and researchers suspect that his extreme size was a result of this hormonal imbalance. They were investigating the underlying causes of his unusual condition to better understand similar cases in amphibians.

Researchers have discovered a 300-million-year-old fossilized rainforest hidden deep beneath the surface in a coal mine in Illinois, USA. It is the largest forest of its kind ever unearthed and offers an unparalleled glimpse into the ecology of one of the planet’s earliest tropical forests.
Paleobiologists from the US National Museum of Natural History (NMNH) in Washington, DC, and the University of Bristol in the UK identified an extraordinary collection of extinct plants, including club mosses that were over a meter thick and reached heights of more than 40 meters. The fossils were located nearly 100 meters below the surface at the Riola and Vermilion Grove mines in Vermilion County, Illinois.
The forest was encased in mud 300 million years ago when a major earthquake or similar catastrophic event caused the entire area to abruptly sink below sea level. The ancient forest was preserved on a layer of coal, and when miners extracted the coal, the fossilized forest was revealed on the mine’s ceiling.

During a routine colonoscopy on a 59-year-old man, doctors made a surprising discovery - a live ladybug in his colon! The patient had no comorbidities, and his colonoscopy prep involved drinking a gallon of polyethylene glycol, a powerful laxative used to clean the colon. This prep may have helped the ladybug avoid being broken down by stomach acids and digestive enzymes, allowing it to make the full journey through the digestive system.
Doctors think the bug, identified as "Harmonia axyridis", a multicolored Asian ladybug introduced to North America for pest control, entered the man’s body while he was asleep. Though it’s rare for insects to be ingested, it does happen occasionally. How this ladybug survived the entire trip is a mystery, and the case study published in the "AGC Case Reports Journal" doesn’t confirm whether the bug made it out alive.

Playing video games can actually help surgeons perform better in the operating room! Studies have found that surgeons who play video games for at least three hours a week work 27% faster and make 37% fewer mistakes compared to those who don’t.
This is because video games, especially those that require precision and quick reflexes, improve hand-eye coordination, reaction time, and fine motor skills—all of which are essential for surgery. Many modern surgeries, like laparoscopic procedures, require surgeons to control tiny instruments while looking at a screen, similar to playing a game.
Additionally, gaming improves problem-solving skills, focus, and the ability to make quick decisions, which are crucial during high-pressure operations. While playing video games alone won’t make someone a great surgeon, it can certainly sharpen the skills needed for delicate medical procedures.

A remarkable discovery in Siberia has left scientists amazed: the mummified remains of a saber-toothed cat cub, belonging to the species Homotherium latidens. This specimen, preserved in the permafrost near the Badyarikha River, is over 35,000 years old and provides an extraordinary glimpse into this ice-age predator, with intact fur, skin, and paw pads.
The cub, estimated to be just three weeks old at death, offers valuable insights into its anatomy and hunting adaptations. Unlike modern lions, its robust forelimbs and larger jaws suggest reliance on strength and agility to subdue prey. The well-preserved body allows scientists to examine features such as shorter ears and a sturdier neck, pointing to unique evolutionary traits.
DNA analysis of this fossil could unravel critical details about saber-toothed cats’ lineage, which diverged from other felines around 18 million years ago. This discovery highlights the permafrost’s role in preserving ancient life and deepens our understanding of extinct species.

What Happens When You Hold in a Fart? Clare Collins, a professor of nutrition and dietetics at the University of Newcastle, explains that holding in a fart can cause intestinal gas to build up, leading to abdominal distension.
Some of this gas may be reabsorbed into the bloodstream and exhaled through your breath. If held in too long, the gas will eventually escape as an uncontrollable fart.
Research is unclear on whether this increases the risk of conditions like diverticulitis or has no significant impact. Studies also show that a high-fiber diet, like one including baked beans and psyllium, leads to fewer but larger farts.
For digestive health, the best approach is simple: when you feel the need to pass gas, find a private spot and let it go. Holding it in does more harm than good

Hurricanes form when warm ocean water heats the air above it, causing that air to rise quickly. As the warm air rises, it creates an area of low pressure below, pulling in cooler air to replace it. This cycle of warm air rising and cooler air filling in beneath starts to create strong winds.
As the winds pick up, the storm begins to rotate due to the Earth's rotation (Coriolis effect). The storm grows in power, drawing in more moisture and heat from the ocean, and eventually becomes a hurricane when wind speeds exceed 74 mph. The key ingredients for hurricane formation are warm ocean waters (at least 26.5°C or 80°F), moist air, and favorable wind conditions.
As the storm intensifies, it forms a characteristic "eye" in the center, which is surrounded by a dangerous eyewall where the strongest winds and rain occur. Hurricanes can bring heavy rains, storm surges (where ocean water is pushed onto land), and damaging winds that cause widespread destruction. Hurricane Milton, currently one of the strongest storms in 2024, follows this same process.
It has grown to a Category 5 hurricane, with wind speeds reaching up to 180 mph. The storm formed over the warm waters of the Atlantic and rapidly intensified. It is now threatening Florida with life-threatening winds, storm surges, and flooding. Authorities have issued evacuation orders as Milton approaches the coast, expecting it to bring significant destruction across a wide area
Someone needs to just get a sharpie pen and divert that hurricane away from the coast. If the Democrats can do it (so says MGT) then the current group needs to give it a go.

4WD and AWD roughly do the same thing but in different ways, the car is proving power to all four of its wheels. The difference is how that power is > divided between them. An AWD car can allow each wheel to turn at a different rate, while a 4WD car generally has its wheel all turning at the same rate.
This 4WD set up is better for offroad driving, but can cause problems in city driving, where the inside wheels need to turn slower around a corner than the outside wheels do. Because of this, a lot of 4WD cars are designed to be able to switch to rear-wheel drive when the 4WD is not needed
Let me clear this up as a former auto tech: Of course terms like "4WD" and "AWD" aren't absolutes, it is basically marketing, but in general: 4WD referrers to a driveline that has a separate gearbox from the transmission that houses the splitter for the different axles and some different gearing ratios as well (think hi/lo range). AWD typically referrers to a driveline that might use a transaxle on one end with a very simple splitter for the other axle and maybe a variable coupler (like a hydraulic clutch pack) to control the torque but some do not even have the coupler and just drive them all, all of the time. The differential gearing in each axle/transaxle is what lets the wheels "slip" a little in turns so it doesn't stress the driveline too much as is a problem with the more rigid "4WD" setups if they are in 4WD mode and driven on dry pavement.
I can assure you that nearly all permanent, mechanical, 4WD systems have a differential, both between left and right and between front and rear. Like many such my LandRover Defender has a separate gearstick to 'lock' the transfer box (as well as shift from high to low ratio) for use in slippery conditions. So no, in normal use all 4 wheels can turn at slightly different rates, otherwise the stresses would just rip up the tyres. The modern usage of AWD rather than 4WD tends to refer to the vehicle type, as in a car is often referred to as AWD whereas a true off-road vehicle like mine is called a 4WD, but in reality the difference is largely semantic.
Ace, Respectfully disagree. My 2002 van is AWD and handles very well on the road, dry or snow. An 80s Ford pickup we had that was 4WD was very much "all wheels turning same" when the 4WD was engaged. That was fine in the dirt farm fields, but the few times I took it back on paved road while still in 4WD, you could definitely feel the strain. Even on dirt, if you drove in a circle in 4WD it tore up the ground more than if you did the same circle in 2WD mode. (I'm talking slow, calm circle, not "brodies" ) But marketing folks being how they are, it is possible the terms have become more blurred than they used to be. I do know that on the AWD side of things, there are different ways of doing it so not all AWD systems are the same.

Get the transmission fluid in your jeep wrangler changed every 6 months. .
The very careful design of the railroad system takes care of the need for the inner wheel travel at the same speed as the outer wheel - note the curve of the rails and the curve of the truck (wheels). In a turn the outer portion of the outer wheel has a smaller diameter than the inner portion added to the curve on the rail lets the fixed wheels turn at the same speed on the curves
The explanation I always got was the percentage of drive each end had. With 4wd it's 50/50, with AWD it's generally 70/30 or 60/40. Our Escape is Fwd/4wd.
They can gear drivelines for many different ratios regardless of the type of vehicle it is. Examples: I have a little crossover KIA and the service info says it is a true 50/50 power split IF the rear coupler is fully engaged. I also have an older pickup and it says it is more like 30/70 (front/rear).

Studies have shown that when dogs poop, they often align their bodies along a north-south axis, meaning they prefer facing either toward the North or South while avoiding the East-West direction. Scientists believe dogs use this ability to stay oriented in their environment, just like birds and other animals that rely on the Earth's magnetosphere for navigation. This behavior is most noticeable when the Earth's magnetic field is calm and undisturbed. Though we don’t fully understand why dogs do this, it’s likely linked to their evolutionary instincts for survival and spatial awareness.
Mine walk in a circle until it's time, and look at me to make sure they won't be vulnerable. Pretty sure it has nothing to do with direction.
I agree. They are turning around looking for any threats.

Really? I think a lot of thought/science has went into something that really didn't need it.
What. They just want to avoid east/west so the sun is not in their eyes... Aligning with the magnetic field... Wtf did I just read
Blushing is something only humans do, and it’s one of the most fascinating and unique reactions of our body. It happens when we feel embarrassed, shy, or even guilty. The reason behind this is tied to our emotions and how our body responds to them.
When we feel a strong emotion like embarrassment, our brain sends a signal to our body to release adrenaline. Adrenaline makes our blood vessels widen, especially in our face, which causes more blood to rush to the skin. This is why our cheeks turn red when we blush. It’s an automatic response, meaning we can’t control it, no matter how much we might want to!
Scientists believe blushing is linked to human social behavior. It’s a way of showing others that we recognize a mistake or feel shy about something. In a way, it helps people trust us more because it signals honesty. Other animals may show emotions in different ways, but blushing is something only humans experience. It’s a reminder of how deeply connected our emotions and physical reactions are.
From the BBC: "Researchers in France have discovered that a hen's facial expressions can reveal a lot about how it's feeling. By looking at how hens - female chickens - respond to different situations, the researchers found that the animals give human-like blushes when feeling scared or excited. Blushing is when someone's skin goes redder due to a rush of blood, in humans it is associated with being embarrassed. In this study the exposed skin around the chickens' faces was monitored to see if it changed colour when they were picked up or heard a loud noise. The scientists saw that the skin got redder when the birds were in a more stressful situation." 25 July 2024
Patently false. Former zookeeper here, and many animals (especially bare-faced primates) will gain a pinkish hue in their skin during periods of excitement or stress. It's just not as visible due to anatomy.
Not trying to sound racist, but do African Americans blush? I'm a tan Italian American and only my ears turn red when I'm mad or overheated. Just curious.
Blushing is a trait in ALL humans, it may or may not be more visible due to skin color. This does sound a bit ignorant.

Researchers have discovered a 300-million-year-old fossilized rainforest hidden deep beneath the surface in a coal mine in Illinois, USA. It is the largest forest of its kind ever unearthed and offers an unparalleled glimpse into the ecology of one of the planet’s earliest tropical forests.
Paleobiologists from the US National Museum of Natural History (NMNH) in Washington, DC, and the University of Bristol in the UK identified an extraordinary collection of extinct plants, including club mosses that were over a meter thick and reached heights of more than 40 meters. The fossils were located nearly 100 meters below the surface at the Riola and Vermilion Grove mines in Vermilion County, Illinois.
The forest was encased in mud 300 million years ago when a major earthquake or similar catastrophic event caused the entire area to abruptly sink below sea level. The ancient forest was preserved on a layer of coal, and when miners extracted the coal, the fossilized forest was revealed on the mine’s ceiling. 📸- Howard falcon-Lang
At least half of these are wrong. Why does a group specifically exist to lie to 5 year olds? I'm thinking this is a group of 5 year olds trying to fool people into believing them.
