Hungry brainHumans aren't unique in this regard. Together with Duke University evolutionary anthropology graduate student Arianna Harrington, who studies energy usage in mammal brains, Boyer conducted research revealing that very small mammals such as the tiny tree shrew and the minuscule pygmy marmoset devote just as much of their body energy to the brain as humans do. Boyer believes the reason i
It's extremely easy to trick our brains — and we are oddly delighted by it. But there's also a practical side to illusions, learning about where the brain gets confused can help us understand how it works to organize information in the first place. Sometimes, a few splashes of color arranged in a very specific way can scream "mistake" to the brain. In response, brain cells will begin to fire to "c
Some 3,700 years ago, a meteor or comet exploded over the Middle East, wiping out human life across a swath of land called Middle Ghor, north of the Dead Sea, say archaeologists who have found evidence of the cosmic airburst. The airburst "in an instant, devastated approximately 500 km2 [about 200 square miles] immediately north of the Dead Sea, not only wiping out 100 percent of the [cities] and
Modern men's genes suggest that something peculiar happened 5,000 to 7,000 years ago: Most of the male population across Asia, Europe and Africa seems to have died off, leaving behind just one man for every 17 women. This so-called population "bottleneck" was first proposed in 2015, and since then, researchers have been trying to figure out what could've caused it. One hypothesis held that the dro
The 2,100-year-old mummified remains of what was thought to be a "hawk mummy" actually belong to a stillborn boy who suffered from anencephaly, a rare condition in which part of the brain and skull fails to develop. "The whole top part of his skull isn't formed," Andrew Nelson, a bioarchaeologist and professor of anthropology at the University of Western Ontario, said in a statement. "The arches o
James Harrison giving his final blood donation on May 11, 2018. It's estimated that his 1,173 donations helped save the lives of more than 2 million babies. (Image credit: Subel Bhandari/DPA/Zuma) A man in Australia helped save the lives of more than 2 million babies by donating his "special" blood, which was used to make a medication that can prevent life-threatening problems in newborns. But why
A famed archaeologist well-known for discovering the sprawling 9,000-year-old settlement in Turkey called Çatalhöyük seems to have faked several of his ancient findings and may have run a "forger's workshop" of sorts, one researcher says. James Mellaart, who died in 2012, created some of the "ancient" murals at Çatalhöyük that he supposedly discovered; he also forged documents recording inscriptio
Captured in a dramatic photo shared yesterday (Feb. 1) to Imgur, a grim scene hints at a violent battle to the death between two giant snakes, identified in the caption as a reticulated python (Python reticulatus) and a king cobra (Ophiophagus hannah), both native to Southeast Asia and among the biggest snakes in the world.
Delicate strands of extraordinarily thin ice grow out of rotting tree branches like hairs on a head. The ephemeral hair ice can last for only a few hours to a few days if the temperature stays freezing. Researchers have known that cold-tolerant fungi are responsible for the tufts of ice, but only recently uncovered the species responsible for the ice growth, the chemical composition of the melted
The moonfish, which are about the size of a manhole cover, is now considered the first-known warm-blooded fish, scientists report in the journal Science. Through some physiological tricks, the fish is able to keep its entire body — heart, brain, swimming muscles and viscera — warmer than the surrounding water. Here are photos of the distinguished fish, which is also called an opah. [Read the full
Why do straight men devote so much headspace to those big, bulbous bags of fat drooping from women's chests? Scientists have never satisfactorily explained men's curious breast fixation, but theorists are gonna theorize. So let's take a tour of the sexy speculation surrounding the human bosom — with a few stops to explain why it's so hard to figure out just why breasts hold such allure. Mammary gl
The study of consensual nonmonogamy is a relatively new field. In the 1970s, partner-swapping and swinging (recreational sex outside of a relationship) came into the public eye, and psychologists conducted a few studies. But that research was limited to mostly white, heterosexual couples who engaged in swinging for fun, according to Elisabeth Sheff, a legal consultant and former Georgia State Univ
"They've pulled off the trifecta of controversial topics," said Brian Nosek, a social and cognitive psychologist at the University of Virginia who was not involved in the study. "When one selects intelligence, political ideology and racism and looks at any of the relationships between those three variables, it's bound to upset somebody." Polling data and social and political science research do sh
