Phys.org / Diets high in a particular type of fat help protect bees against pesticides
Diets rich in polyunsaturated fatty acids—a type of fat that supports brain function, cell growth and heart health—may help protect honey bees against the toxic effects of pesticides, according to a study led by researchers ...
Phys.org / Record snow drought drives water-hauling crisis for Rocky Mountain ranchers
As water shot into an open stock tank atop a high-country mesa, a trickle soaked the dusty earth below. Scott Snyder rose from the shade to fasten a hose and stop the spillage.
Phys.org / Scientists' biographies may demotivate, not inspire, children to study science
Currently popular biographies of famous scientists may demotivate—rather than inspire—children's desire to study or pursue careers in science, according to researchers who studied the messages in 422 bestselling children's ...
Phys.org / Scientists uncover two new ways doxycycline disables bacterial ribosomes
Scientists have discovered two new mechanisms for how a well-established antibiotic works, paving the way for the potential development of new antibiotic treatments.
Phys.org / Scientists cut and rebuild molecules from the inside to create new chiral nanocarbons
Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...
Phys.org / Helical nanoparticles trigger cancer alarms and deliver gene therapy
Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while ...
Phys.org / Neuroscientists reveal limits of human compassion for global crises
New research from the University of Sussex has revealed the biological limits to human compassion and empathy. The study found a stark contrast between how the brain processes information about risk to human lives and information ...
Phys.org / Queen bee pheromones help daughters decide whether to stay or leave the nest
Female sweat bees need to make a pivotal life decision: remain in the nest to help their mother raise more offspring or leave to establish nests of their own. New research from the Smithsonian Tropical Research Institute ...
Phys.org / Small ants that evict coffee pests may gain reproductive boost while protecting crops
Ants are known allies in the fight against coffee pests known as coffee berry borers. Now, a discovery made by Jonathan "Jonno" Morris while he was a University of Michigan graduate student has revealed there may be a new ...
Phys.org / AI-powered camera system offers low-cost way to monitor bumblebees, potentially other insects
Researchers have developed a low-cost, semi-automated, AI-driven method that uses remote cameras to survey bumblebees and potentially other insects. The new tool could have important implications for efforts to conserve declining ...
Phys.org / 'Rivers in the sky' influence marine heat waves
Long, narrow bands of moving moisture in the sky, known as atmospheric rivers, contribute to heat waves in the marine environment, according to a new study published in Nature Communications by researchers from Duke University's ...
Phys.org / AI models explain 17% of earnings-day stock moves, up from 5%
To explain the stock market's reaction to earnings results, investors and other market participants have used a standard tool for decades: the earnings surprise.
