In the dead of night, 200 bloodthirsty creatures make their way through a tented mesh arena the size of an ice rink. Scientists study them from afar, pumping in air scented with the aroma of human prey. They’re hoping to reveal just what triggers these deadly predators. This isn’t the setup for an upcoming zombie movie. “It’s the world’s largest multichoice smell test...

Many pet owners are watching the smoky skies all over Western Canada and wondering just how worried they should be about their furry...

From carpets to toilet paper, these persistent manufacturing chemicals are everywhere. Here's what to know.

Ketamine is a powerful anesthetic and sometimes recreational drug that causes people to feel dissociated from their own bodies. Recent studies suggest the drug may help treat people with depression who have tried more conventional treatments without success. But there are major questions about what makes it work. Is it the weird dissociative experience? Some molecular effect on the brain?...

NASA has selected Blue Origin's Blue Moon as the second human landing system that will take future astronauts to the Moon. The post Blue Origin’s Blue Moon will become second Artemis lander appeared first on Astronomy...

Bob McDonald's blog: Astronomers are asking for the public's help to scan through thousands of images of the night sky to search for undiscovered asteroids — some of which have the potential to collide with...

The course of human history has been marked by complex patterns of migration, isolation, and admixture, the latter a term that refers to gene flow between individuals from different populations. Admixture results in a blending of genetic lineages, leading to increased genetic diversity within populations. In addition to admixture among modern human populations, ancient humans reproduced with other...

In a new study published in eLife, lead author Carolyn Elya, postdoctoral researcher in the Department of Organismic and Evolutionary Biology at Harvard, reveals the molecular and cellular underpinnings behind the parasitic fungus, Entomophthora muscae's (E. muscae), ability to manipulate the behavior of fruit flies.

The National Science Foundation's (NSF) Daniel K. Inouye Solar Telescope released eight new images of the sun, previewing the exciting science underway at the world's most powerful ground-based solar telescope. The images feature a variety of sunspots and quiet regions of the sun obtained by the Visible-Broadband Imager (VBI), one of the telescope's first-generation instruments.

Polygenic scores—estimates of an individual's predisposition for complex traits and diseases—hold promise for identifying patients at risk of disease and guiding early, personalized treatments, but UCLA experts found the scores fail to account for the wide range of genetic diversity across individuals in all ancestries.

The massive, star-forming interstellar cloud Lupus 3 is captured with the 570-megapixel US Department of Energy-fabricated Dark Energy Camera at NSF's NOIRLab's Cerro Tololo Inter-American Observatory in Chile. The dazzling central region of this sprawling cloud reveals a pair of infant stars bursting from their natal cocoons of dust and gas to illuminate the reflection nebula known as Bernes 149....

The nucleobase molecules carrying the genetic codes are the most important ingredients for life, but they are also very vulnerable. When the ultraviolet component in the sunlight irradiates these molecules, the electrons in the molecules will be excited, and the excited nucleobase molecules may result in irreversible changes or even damages to the DNA and RNA chains, leading to the "sunburn" of...

Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation.

Jeff Bezos' rocket company has won a NASA contract to land astronauts on the moon, two years after it lost out to SpaceX.

Antonio Vento is 13 years old. He’s a tiny figure in bandages who doesn’t walk and, until recently, couldn’t see more than shadows. He has dystrophic epidermolysis bullosa, an inherited disease that makes his skin so fragile that kids with the illness are called “butterfly children.” But now, thanks to a novel gene therapy squirted onto his skin and dripped into his eyes, things are...

The floods that sent rivers of mud tearing through towns in Italy's northeast are another drenching dose of climate change's all-or-nothing weather extremes, something that has been happening around the globe, scientists say.

The brush-tailed bettong—a rare, very cute marsupial resembling a rabbit-sized kangaroo—is bouncing back on the South Australian mainland, more than 100 years after disappearing from the region.

A 7.7 magnitude earthquake caused a small tsunami to wash ashore on South Pacific islands Friday. No damage has been reported, and the threat passed in a few hours.

Satellite-derived bathymetry continues to advance and improve rapidly. A recent study has confirmed the effectiveness of a methodology developed to obtain bathymetric data from satellite images in the Western Mediterranean. The results of this research, published in the International Journal of Applied Earth Observation and Geoinformation, reaffirm the value of this tool for monitoring coastal...

A crowd of beachgoers cheered and hollered on Tuesday as they watched Mote Marine staff release two loggerhead sea turtles, named Lilly and Farmer, into the water at Lido Beach in Sarasota.
