Phys.org / Goats listen to human voices to find hidden food treats
Goats appear to have a rare ability not shared by many in the animal kingdom, and that is being able to follow the direction of a human voice to locate hidden objects. While dogs have been shown to do this, even our closest ...
Phys.org / Quantum Hall effect gains a new twist in graphene moiré systems
Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...
Phys.org / Atlantic and Pacific may follow different rules on long-term warming, analysis shows
Florida State University researchers have identified key differences in the root causes of long-term sea-surface temperature changes across the Atlantic and Pacific oceans, a finding that could help guide future research ...
Medical Xpress / Legalizing cannabis increases use and addiction, unless it is tightly controlled, says research
Removing criminal penalties for possessing cannabis for personal use, or introducing tightly controlled legalization of cannabis, does not appear to increase levels of cannabis use. However, the commercial sale of cannabis ...
Phys.org / Baby fossils reveal link between human and Neanderthal development
An international study of infant remains from 50,000–75,000 years ago has provided new evidence about the developmental trajectory of our evolutionary "cousins," Neanderthals.
Medical Xpress / Colorectal tumors use mitochondrial complex II to stockpile iron, but eliminating it causes cell death
Scientists know that colorectal cancer cells require large amounts of iron and that as cancer becomes more aggressive, the cells have even higher amounts of iron. Normal cells with high levels of iron would undergo a type ...
Medical Xpress / Pakistani genomes reveal 34,000 knockouts that could explain why mouse-based drugs fail in humans
A comprehensive analysis of 173,303 genomes from Pakistan, published today in Nature, is upending how scientists understand human genetics and drug development. By identifying 34,000 people who are "human knockouts," with ...
Tech Xplore / Electric 'nose' can smell when your food's gone bad
Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. ...
Phys.org / Floating litter extends over Chesapeake Bay, the largest estuary in the US
A study led by researchers from the Smithsonian Institution and the UB reveals that reducing single-use plastic is essential for protecting coastal ecosystems. Floating litter has also invaded Chesapeake Bay, the largest ...
Phys.org / Mars mission simulations reveal key to teamwork under pressure
Whether it's to the moon or Mars, a NASA mission requires some essential preparations: designing and developing the spacecraft, astronaut training and safety checks, clear goals, and strategies and procedures for maintaining ...
Phys.org / Supernova origins explored through primordial black holes
Dr. Shing-Chi Leung, assistant professor of physics at SUNY Polytechnic Institute, has published the article "Primordial Black Hole Triggered Type Ia Supernovae II: Comparison with Supernova Remnants and Galactic Chemical ...
Medical Xpress / Parents of newborn girls are more likely to refuse lifesaving vitamin K and hepatitis B vaccine shot, researchers find
A simple shot given shortly after birth can protect babies from a rare but potentially life-threatening condition known as vitamin K deficiency bleeding (VKDB). When newborns don't have enough vitamin K, their blood can't ...
