Researchers at Keio University spent weeks showing laboratory mice footage of mouse porn, mouse fights, and mouse sniffing. They found out that mice can distinguish between social behaviors—and that they prefer seeing fighting to sex, unless drugs are involved.
Researchers at Johns Hopkins Bloomberg School of Public Health have produced tiny brains made of human neurons and cells. These mini-brains could radically change how drugs are tested, replacing the many animals currently being used for neurological scientific research.
Australia’s iconic koala—a species already threatened with extinction—is currently in the midst of a devastating chlamydia epidemic. Some scientists are now arguing that in order to save these cute marsupials from extinction, we may have to euthanize them in a massive cull.
Ground-nesting wasps are incredibly good at navigating the world, particularly when it comes to re-locating their nests. By tracking the intricate flight patterns and visual focus of these insects, scientists have simulated what a wasp sees as it makes its journey back home.
Last August, photographer Will Burrard-Lucas undertook an assignment for the World Wildlife Fund in the Zambezi Region of Namibia. Over the course of the next three months, his high definition camera traps snapped remarkable images of the region’s most elusive wildlife. Here are the very best photos of the lot.
A new study in the New England Journal of Medicine is bolstering a potential link between Zika and microcephaly, a rare birth defect in which babies are born with abnormally small heads.
It’s well established that older men are more likely to pass on a genetic disorder to their offspring, but we’re learning more about why this happens: As men age, their sperm mutates more frequently. This is bad news for men who want to have children later in life.
Since 1954, Kyoto University has been managing a population of fruit flies, living in total darkness. Now, after interbreeding some of these “dark flies” with regular flies, the researchers are learning more about the genetic adaptations taking place when fruit flies are kept entirely in the dark.
Movies like Eternal Sunshine of the Spotless Mind and Inception suggest it may eventually be possible to erase, modify, or even implant memories into your brain. An upcoming episode of NOVA introduces viewers to this futuristic possibility and the scientists who are trying to make it happen.
If you’ve ever gone skinny-dipping and had the creepy feeling you were being watched, you were right. The green slime floating on the surface of the water and coating the rocks was watching you. And it was doing it using eyes similar to your own human ones. That’s according to new findings by a team of scientists from…
Researchers from 21st Century Medicine have developed a new technique to allow long term storage of a near-perfect mammalian brain. It’s a breakthrough that could have serious implications for cryonics, and the futuristic prospect of bringing the frozen dead back to life.
The largest island in the Hawaiian archipelago has recorded nearly 250 cases of dengue fever since the start of September, prompting officials to declare a localized state of emergency.
Ticks—those unbreakable, blood-lusting arthropods that haunt your summer camp memories—have some fascinating genetic secrets. The tick genome tells a tale of weaponized spit, expandable armor, and how to drink 100 times one’s body weight in blood. Strangest of all, it’s utterly enormous.
The mollusks pictured above are either getting ready for Coachella, or showcasing an intriguing new species of sea creature. This just-discovered type of polyp spends its life decorating the shells of snails.
The U.S. Centers for Disease Control and Prevention is asking pregnant women to abstain from sex if their partner has recently visited an area where Zika is currently active. The CDC’s updated guidelines also offers advice for men and their nonpregnant partners.
A small segment of the population is literally allergic to vibrations, an annoying condition that gives rise to hives and other symptoms. Researchers at the NIH have now isolated the genetic mutation responsible for the disorder, and it’s offering new insight into related conditions.
In 1985, a premature baby was born in Maryland who needed surgery to tie off a dangerous blood vessel near his heart. The newborn, Jeffrey, died weeks after the procedure. His family learned afterwards that none of the procedures had been performed with analgesics; the only drug administered was a muscle relaxant.
Here’s a fun fact to chew on while planning your next vacation: the southwestern United States is brimming with tarantula diversity. Today in the journal ZooKeys, biologists describe 14 previously unknown species of tarantulas living in the American Southwest, including Aphonopelma johnnycashi. Country music legend…
By flushing out cells worn with age, researchers from the Mayo Clinic have extended the lifespans of mice by as much as 35 percent. It’s an encouraging finding that could eventually lead to similar therapies in humans.
A controversial fertility treatment requiring three genetic parents has been approved by an FDA-appointed expert panel. This means the therapy, which eliminates rare mitochondrial diseases, could soon be legal in the US. But on the recommendation of the panel, it won’t be available to girls.
