Bird feeding helps females more than males
A new study shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to reduce their body temperature as...
Mixture and migration brought food production to sub-Saharan Africa
A new interdisciplinary study reports on 20 newly sequenced ancient genomes from sub-Saharan Africa, including the first genomes from the Democratic Republic of the Congo, Botswana, and Uganda. The study...
Motion Picture Academy sets new diversity initiatives
The Academy of Motion Picture Arts and Sciences announced its Academy Aperture 2025 program on Friday. The program includes new Oscars eligibility rules, board of governors term limits and new...
Protein degradation–focused Lycia Therapeutics launches with $50 million from Versant
Using technology from chemical biologist Carolyn Bertozzi's lab, the firm wants to develop drugs that can break down extracellular proteins
The best plant parents: Genetically as divergent as possible with similar preferences
A team of researchers led by IPK Gatersleben has succeeded in providing answers to a long unsolved question in the breeding of plant hybrids. Their conclusions: the more diverse in...
Mixture and migration brought food production to sub-Saharan Africa
A new interdisciplinary study published in the journal Science Advances reports on 20 newly sequenced ancient genomes from sub-Saharan Africa, including the first genomes from the Democratic Republic of the...
Watch: Florida man fist-fights alligator to save dog
A Florida man said he ended up in a fist fight with a 13-foot alligator when the reptile attacked his dog and pulled the canine into the water.
Bird feeding helps females more than males
A new study from Lund University in Sweden shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to...
Scientists trigger hibernation in mice, astronauts could be next
Scientists in Japan successfully triggered a hibernation-like state in mice by activating a specific group of brain cells.
Clues to aging come to light in vivid snapshots of brain cell links
Striking images of some five billion brain cell connections have been created by scientists, mapping a lifetime's changes across the brain in minute detail.
HBO Max renews 'Love Life' for a second season
Romantic comedy anthology series "Love Life" has been renewed for a second season by HBO Max.
Researchers identify new approach to turning on the heat in energy-burning fat cells
Researchers have discovered a new set of signals that cells send and receive to prompt one type of fat cell to convert fat into heat. The signaling pathway, discovered in...
New machine learning model predicts which base editor performs best to repair thousands of disease-causing mutations
Gene editing technology is getting better and growing faster than ever before. New and improved base editors—an especially efficient and precise kind of genetic corrector—inch the tech closer to treating...
The rise of the 'liberaltarian'
Political economists Neil Malhotra and David Broockman have documented a new species of political animal: the liberaltarian.
Statistical analyses of plant metabolites allow solid testing of plant defense theories
Do plants attacked by herbivores produce substances that are most effective against attackers in a targeted manner, or are herbivore-induced changes in a plant metabolism random, which could thwart the...
Versatile symbionts: Reed beetles benefit from bacterial helpers through all life stages
Insects that feed only on plants have a number of challenges to overcome. But they also have some active helpers to assist them with the supply of important nutrients. So-called symbiotic microorganisms make...
Study reveals impacts of climate change on migrating mule deer
When drought reshuffles the green-up of habitats that mule deer migrate across, it dramatically shortens the annual foraging bonanza they rely on.
Water bacteria have a green thumb
The sheer endless expanses of the oceans are hostile deserts—at least from the perspective of a bacterium living in water. Tiny as it is, its chances of finding sufficient nutrients...
From bacteria to you: The biological reactions that sustain our rhythms
Every second of every day, countless biochemical reactions take place in our bodies' cells. The organization of this complex system is the result of billions of years of evolution, fine-tuning...
Single enzyme responsible for gender-based plumage color differences in canaries
A team of researchers affiliated with multiple institutions in Portugal and the U.S. has found that a single enzyme is responsible for gender-based plumage color differences in mosaic canaries. In...
Scientists report heavy ion transfer in charged vdW cluster for the first time
Since the discovery of the double helix form of DNA and the hypothesis of DNA mutation induced by proton transfer more than 50 years ago, it has been recognized that...
Using light to speed up CRISPR-Cas9 gene editing
A team of researchers at Johns Hopkins University has developed a way to speed up the CRISPR-Cas9 gene-editing process by using light-sensitive nucleotides. In their paper published in the journal...
Environmental DNA shows promise in estimating sport fish populations
Anglers often lament how hard it can be to land a fish for dinner, but the tougher job usually falls to fisheries managers, who have set sustainable catch limits for...
Unlocking PNA's superpowers for self-assembling nanostructures
Researchers at Carnegie Mellon University have developed a method for self-assembling nanostructures with gamma-modified peptide nucleic acid (γPNA), a synthetic mimic of DNA. The process has the potential to impact...
An El Niño hit this banana prawn fishery hard. Here's what we can learn from their experience
Prawns are a staple of many Australian barbecues, and we're fortunate to have wild-caught prawns from sustainably-managed fisheries that boast best management practice.
"Forever Chemicals" Are Building Up in the Arctic--and Likely Worldwide
