An ‘Extremely Rare’ Half-Male, Half-Female Bird Temporarily Took Up Residence Outside of Chicago
The unusual-looking bobolink is what’s called a bilateral gynandromorph. The bird behaved like a male, eventually wooing a mate and raising fledglings
NASA-Funded Mission to Rescue a Falling Space Telescope Officially Ends in Failure
The commercial LINK spacecraft was supposed to give NASA’s Swift observatory a boost, pushing it higher into orbit to extend its life. But after launch, LINK experienced several problems. Swift is expected to re-enter Earth’s atmosphere and burn up by the end of this year
The Arctic whales are the only known animals with straight tusks, and ones that consistently twist to the left. New research reveals that the inner layer twists to the right and that the opposing spirals provide strength and help the tusks grow straight
No written records mention a fight in this specific part of Vienna at the time of the men’s deaths. But the brutal nature of their injuries, particularly to the pelvis area, indicates that these individuals died on the battlefield
The bones were discovered on the Dingle Peninsula more than 30 years ago, but scientists recently decided to take another look at them, this time using modern techniques
Under the right conditions—wet and oxygen-deprived—the same chemical reactions that cause tissue to break down can instead have the opposite effect, according to a new study
Researchers thought that insects might not live there because their respiratory systems would implode from water pressure. But certain fly larvae in East Africa make daily trips toward the bottom of Lake Malawi with the help of strong air sacs that contain a stretchy protein
Scientists discovered a strange feature in certain octopuses’ ribosomal RNA, molecules that create a 3D scaffold for cellular protein factories. It was found only in shallow-water creatures that have expanded nervous systems and can do complex behaviors
Extremely wet conditions are known to help spread mosquito-borne diseases like yellow fever. But based on computer simulations, researchers suspect that a severe drought may have contributed to the South American country’s recent deadly epidemic
This social behavior might reveal the evolutionary roots of traits that underlie pet-keeping in humans, scientists say, from caregiving to tolerance and curiosity. But it’s not the same as a person keeping a cat or a dog
The Food and Drug Administration just greenlit a medication called Orzeyful for the treatment of narcolepsy type 1 in adults. The condition is caused by the loss of brain cells that produce orexin, a chemical important for regulating the sleep-wake cycle
Fish surveys in the 1960s detected what experts thought was a dead coral reef barrier off the country of Benin. Decades later, researchers set off in small fishing boats to investigate it using sonar mapping, underwater drone surveys and stationary video recorders
High blood pressure, diabetes and smoking are three major modifiable risk factors of dementia. New research tracked more than 12,000 participants to quantify how many years of healthy cognitive function you can gain by evading some or all of them during middle age
The galaxy’s light took about 12.5 billion years to reach the James Webb Space Telescope, meaning the instrument saw the black holes a little more than one billion years after the Big Bang. Two of the black holes seemed on track to merge, illustrating how the objects grow
A bone feature found in a mammal ancestor hints that the creature was relatively large as a newborn, more in line with the size of a creature birthed live than hatched from an egg. Still, it provides only indirect evidence
Listen Up, Parents: Running With a Stroller Might Make You Less Prone to Overuse Injuries
Runners often experience conditions like shin splints, runner’s knee and plantar fasciitis, which causes pain in the bottom of the heel. But pushing a stroller’s handlebar seems to make you distribute your weight differently
Most people carry a sleeping virus in their bodies, such as the herpesvirus that causes mononucleosis, or the “kissing disease.” A new study hints that Covid-19 triggers their reactivation, which could worsen symptoms and increase the risk of long Covid
A skeleton unearthed in Scotland likely belongs to a soldier struck by a high-speed projectile during Edward I’s 1304 siege of Stirling Castle. The man suffered more than 160 fractures
Since the James Webb Space Telescope started collecting data in 2022, it has found puzzling objects dubbed little red dots. A new study suggests they might be giant black holes with some characteristics of stars
Here’s Why These Male Spiders Sacrifice Themselves by Somersaulting Into Females’ Fangs While Mating
A new study suggest that even strange, complex animal behaviors can have a relatively simple genetic basis
