Phys.org / Honeybee queens push pesticides to eggs to protect themselves over their offspring, research reveals
Worker bees are the first line of defense when it comes to removing contamination in honeybee colonies, but a queen has her ways, too. A honeybee queen facing chronic exposure to pesticides will take up that contamination ...
Phys.org / Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water ...
Phys.org / 400-year-old painting reveals a bat's secret diet
Natural historians have many observational techniques in their toolkit for learning about the natural world: tagging animals with tracking devices, recording sounds, analyzing droppings or simply watching and counting. As ...
Medical Xpress / Long sitting bouts linked to increased cancer risk
Each additional hour of prolonged, uninterrupted sedentary behavior in a person's day is associated with a 9% higher risk of cancer death, according to a study published in PLOS Medicine by Frederick Ho of the University ...
Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork
Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...
Phys.org / How a giant planet survived its star's death, then migrated inward
When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star's violent demise. Now, observations from NASA's James Webb Space Telescope (JWST) may finally explain the planet's ...
Tech Xplore / Blame the model, not the machine—better data helps 3D-printed metamaterials match predictions
Additive manufacturing, such as 3D printing, provides an excellent opportunity to design metamaterials: materials with an engineered structure that leads to desired properties such as, for instance, resistance to vibrations. ...
Phys.org / Instant digital rewards may make hard thinking feel less worthwhile
Imagine opening a difficult book in a quiet room. The first page is dense. You read one paragraph, then reread it. Nothing "clicks" yet. Your brain is doing what learning often requires: spending effort before the reward ...
Phys.org / Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. ...
Phys.org / Plant DNA harbors virus 'fossils' that reflect 300 million years of evolution
Is it possible to study the history of viruses that emerged several hundred million years ago? An international team of INRAE and CIRAD researchers answered this question by exploring plant genomes to find the molecular fossils ...
Medical Xpress / Men should speed up slower to avoid 'hitting the wall' in marathons, new research suggests
Male runners may be twice as likely as female runners to suddenly slow down—known as "hitting the wall"—during a marathon, according to a study published in Scientific Reports. The authors suggest that men may be able to ...
Phys.org / Algae may have launched coral reefs by hijacking coral cells, genetic experiments suggest
The reefs scattered throughout the tropics arose only after algae took up full-time residence in coral cells, supplying corals with abundant food and enabling them to build extensive shallow-water communities. But with warming ...
