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 / 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 / More evidence Mars once had water emerges from old Spirit rover data
More than 20 years after NASA's Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.
Phys.org / Chicxulub's lingering dust may have turned falling debris into a global firestorm
Sixty-six million years ago, the six-mile-wide (10-kilometer-wide) Chicxulub asteroid crash-landed in Mexico's Yucatán Peninsula and changed life on Earth forever. The reign of the dinosaurs ended, and only creatures that ...
Phys.org / A way to read quantum bits faster and with less hardware
Quantum computers process information in a fundamentally different way from conventional computers, using quantum bits, or qubits, that can exist in multiple states at once. This could allow them to tackle problems beyond ...
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 / 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 / Juvenile great white sharks fled their nursery during tropical storm Hilary, research reveals
In August 2023, communities across Southern California braced for Tropical Storm Hilary—the first tropical storm to directly impact the region this century. Although the storm weakened from a Category 4 hurricane before making ...
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 ...
