A loss of controlled inhibition of overly excited brain cells might explain how a common knock-out anesthesia drug works. A new animal study led by researchers from the Massachusetts Institute of Technology (MIT) has found that propofol, a sedative used to safely lull people into unconsciousness for medical procedures, disrupts the brain's normal ability to regain control of highly excitable neurons.

Common Sedative Could Break Consciousness by Tipping Your Brain Into Chaos

A fragment of skin trapped in permafrost for 52,000 years has just given us a marvelous world first.
Left by a wooly mammoth (Mammuthus primigenius), the material has delivered unto us not just a genome, but a three-dimensional reconstruction of the once-magnificent animal's chromosomes.



					
			

"This is a new type of fossil, and its scale dwarfs that of individual ancient DNA fragments – a million times more sequence," says geneticist Erez Lieberman Aiden of Baylor College of Medicine in the US.
"It is also the first time a karyotype of any sort has been determined for an ancient sample."
The last wooly mammoths died off...

The secret to pterosaurs taking flight long before birds and bats dominated the air was wasn't feathers or hollow bones.
Although those features no doubt helped, new research shows that a lattice-like structure stopped pterosaurs' broad-ended tails fluttering like flags in the wind and instead, once stiffened, helped guide these flying reptiles into the sky.



					
			

Pterosaurs took to the skies using powered flight about 215 million years ago, the first vertebrates to do so. Although they started out small, amongst their ranks were some of the largest flying animals in Earth's history.
Like birds, pterosaurs had feathers, but they weren't birds, nor were...

Scientists Can Finally Reveal The Secret of How Pterosaurs Took Flight

The idea that animals' brain mass and body mass are correlated makes intuitive sense: larger animals, after all, tend to have larger brains than their smaller cousins. However, it's proven difficult to find a definitive model for exactly how these two figures relate to one another. A new study published...

The Mystery of How Big Animal Brains Should Grow May Finally Be Solved


Being curious is a quintessential part of being human, driving us to learn and adapt to new environments. For the first time, scientists have pinpointed the spot in the brain where curiosity emerges.



					
			

The discovery was made by researchers from Columbia University in the US, who used functional magnetic resonance imaging (fMRI) scans to measure oxygen levels in different parts of the brain, indicating how busy each region is at any one time.
Knowing where curiosity originates could help us understand more about how human beings tick, and potentially lead to therapies for conditions where curiosity is lacking, such as chronic depression.

Do your loved ones consult you regularly when they face a crisis? Intelligence is a branch of psychology that lacks a standard definition. Some scientists claim that it is a single ability and others state it comprises aptitudes and skills. Intelligent zodiac signs learn from their experiences and easily recognize and solve problems.

In the guts of an ancient mummified crocodile, researchers have discovered a telltale bronze hook.
Up to 3,000 years ago, the 2.2-meter (7.2-foot) long crocodile died before it had even begun to digest a fish found intact around the hook in its stomach.



					
			

The human-made object and state of the carefully preserved animal suggest it was deliberately caught in the wild and processed as an offering to the Egyptian crocodile god, Sobek.
Luckily, the ancient Egyptians who prepared the croc's body for mummification didn't remove its guts, as was common practice for human mummies. This allowed a UK team of researchers to reveal...

Shortly before 3 AM, people in the Chicago area may have felt their houses shake as a 3.4-magnitude earthquake occurred about 60 miles west of the city. (CHICAGO) The United States Geological Survey (USGS) reported a 3.4-magnitude earthquake around Somonauk, IL. Somonauk is in DeKalb and LaSalle Counties, 64 miles west of Chicago.

Did You Feel the Earthquake?

Deciding on which zodiac signs are the most dangerous is not an easy task as there could be many ways of determining what is considered dangerous. Dangerous of course could be a very subjective idea. Your own sign could also weigh heavily in making this list as certain signs, as we know, tend to be more compatible with some than others. So, what am I going to make these predictions based on? I am thinking that looking at the most formidable and dangerous people in our history might be a good way to make the determination of the most dangerous signs. Let’s see what we can learn.

(MA) Get ready to meet three little balls of fluff who are ready to fill your heart, and life, with love. Brynn, Bambi, and Bubbles Bath are 6-week-old Great Pyrenees mix sisters who were found as strays living under a porch. Sadly, their mother, also a stray, did not allow herself to be caught and brought into rescue alongside her babies. Despite that, the three puppies are healthy and happy in their new foster home. They have a bright future ahead of them, assuming YOU adopt them! Or, maybe you don't want pure joy, cuteness, and fluff-love in your life.

The mysterious, sudden abandonment of the ancient lost city of Cahokia by its inhabitants has been puzzling historians for a long time now – and experts have cast fresh doubt on one of the most popular theories to date. For several hundred prosperous years, Cahokia was the place to...

The Mystery of Lost City of Cahokia's Abandonment Just Got Even Deeper

Once upon a time, Earth was barren. Everything changed when, somehow, out of the chemistry available early in our planet's history, something started squirming – processing available matter to survive, to breed, to thrive.



					
			

What that something was, and when it first squirmed, have been burning questions that have puzzled humanity probably for as long as we've been able to ask "what am I?"
Now, a new study has found some answers – and life emerged surprisingly early.
By studying the genomes of organisms that are alive today, scientists have determined that the last universal common ancestor (LUCA), the first organism that spawned...

Gobsmacking Study Finds Life on Earth Emerged 4.2 Billion Years Ago

No one really knows the cause of migraine, but a number of studies have begun to piece together the mechanisms behind these headaches from hell. There's evidence that short strings of amino acids called calcitonin gene-related peptides (CGRP) could be the evil puppeteers behind painful migraine attacks, with treatments targeting CGRP already on the market. There are also signs that malfunctioning fluid drainage systems in the brain might sometimes involved.

Caitlin Tan wanted to breed her childhood horse, JP, because she’s been “amazing” — the type of animal any equestrian would be lucky to have once in a lifetime. Having access to coveted bloodlines increased the allure. Via the Miller Ranch, she could pair her 18-year-old mare with a stud descendent of Playboy’s Buck Fever.

We spend a third of our lives asleep. And a quarter of our time asleep is spent dreaming. So, for the average person alive in 2022, with a life expectancy of around 73, that clocks in at just over six years of dreaming.



					
			

Yet, given the central role that dreaming plays in our lives, we still know so little about why we dream, how the brain creates dreams, and importantly, what the significance of our dreams might be for our health – especially the health of our brains.
My 2022 study, published in The Lancet's eClinicalMedicine journal, showed that our dreams can...

A dangerous drug that is being mixed into fentanyl is causing those who inject it to develop a rash of sores that resembles a case of flesh-eating bacteria. People experiencing homelessness around Denver can sometimes be seen with these bloody, weeping wounds. I recently mentioned this phenomenon to a fentanyl user who told me about the xylazine connection.

Performing at the absolute pinnacle of athletic endeavor can play havoc on the human body. When you push yourself beyond your limits, you can end up in a world of pain.
There are the injuries, of course. And for the 14,500 or so athletes – and their staff – expected to take up residence in the Olympic Village for the duration of the 2024 Paris Games, there's likely to be a few infections going around.



					
			

But one ailment is shockingly common among top-level athletes, and it's probably not one you might expect. It's estimated that upwards of 20 percent of the athletes...
