Phys.org / Dodos probably weren't as stupid as historians made them out to be: new research
The dodo has been extinct for more than 300 years, wiped out within decades of humans arriving on its home island of Mauritius, but it lives on in the public imagination.
Phys.org / Natural insecticide made from compound found in garlic and spearmint kills bean beetles effectively
In an effort to develop more environmentally friendly alternatives to synthetic insecticides, researchers from Kyushu University have developed and tested a new insecticide made from compounds derived from garlic and spearmint.
Medical Xpress / AI-designed E. coli killer points toward new ways to fight antibiotic-resistant bacteria
In science, the suffix "phage" means to devour. Thus, the name bacteriophage might conjure images of tiny creatures that "eat" bacteria. While that conception isn't 100% scientifically accurate, bacteriophages are lethal ...
Medical Xpress / Birth order may influence your disease risk later in life, study finds
Whether you are first-born or second-born may be associated with your risk of developing certain diseases, according to a new study published in Nature Health.
Phys.org / Two origins of life: Free-living cells may have emerged twice as bacteria and archaea diverged
How and where did the first forms of life arise? These are the main questions driving research at the Institute of Molecular Evolution at Heinrich Heine University Düsseldorf (HHU). In a new publication in Science Advances, ...
Phys.org / Hydraulic traits reveal why some mountain trees move uphill while others shift downhill
As global temperatures rise, scientists have largely assumed that mountain tree species will move uphill in search of cooler conditions. A new study published in Nature Climate Change reveals a more complex reality: Some ...
Phys.org / Zoo-housed lions show wild-style behaviors when fed whole carcasses
A new Australian study has found that feeding zoo-housed lions whole-animal carcasses on a feast-and-fast schedule encourages behaviors more closely aligned with those seen in the wild.
Tech Xplore / Hidden goals can undermine AI teamwork, study finds
Large language models (LLMs), the computational models that underpin conversational agents such as Gemini and ChatGPT, are now widely used by people worldwide to rapidly find information, summarize documents and generate ...
Phys.org / Antenna-like cell appendage may help turtle embryos sense sex-deciding nest temperatures
When most baby turtles hatch, their sex depends on the temperature of the sand or soil where their mother laid her eggs. Warm incubation produces females, while cool nests produce males.
Science X / Virtual escape test exposes hidden rule people use when identical exits create pressure and no sign points way
Ever wonder who you mimic in a line of people heading for an exit? In an emergency, do you trail the person right ahead, or do you watch what everyone else does? It's a question with surprising implications for how we understand ...
Phys.org / Why some people are mosquito magnets while others get away unbitten
Some mosquitoes really are picky eaters. They will not just stick their proboscis into any old human. We know this anecdotally, with some people claiming they are always bitten while others are completely ignored, though ...
Phys.org / Uranus's unusual rotation makes its bow shock expand and contract each day
Within our solar system, Uranus is a geometric oddball. Its spin axis tilts more than 90° from its orbit, so it essentially rolls on its side through space. In contrast, Earth and other planets tilt only moderately or not ...
