Phys.org / Bumble bees launch a three-stage defensive response when their nest is disturbed
Bumble bees respond to physical disturbance of their nest with a sequence of defensive behaviors that lasts up to 10 minutes, according to a study by Sajedeh Sarlak at the University of Konstanz, Germany, and colleagues.
Phys.org / Sargasso Sea shift reveals dramatic decline in some historic seaweed populations
A study led by researchers at the University of South Florida's College of Marine Science has found that certain populations of the seaweed sargassum have experienced a significant decline over the past decade, even as increased ...
Phys.org / Evidence of rain-driven climate on Mars found in bleached rocks scattered in Jezero crater
Rocks that stood out as light-colored dots on the reddish-orange surface of Mars now are the latest evidence that areas of the small planet may have once supported wet oases with humid climates and heavy rainfall comparable ...
Phys.org / For the first time, researchers observe how influenza viruses infect living cells
The flu illness is triggered by influenza viruses, which enter the body through droplets and then infect cells. Researchers from Switzerland and Japan have now investigated the flu virus in minute detail.
Tech Xplore / A smarter way for large language models to think about hard problems
To make large language models (LLMs) more accurate when answering harder questions, researchers can let the model spend more time thinking about potential solutions.
Phys.org / Chlorine and potassium found in supernova remnant at unexpectedly high levels
"Why are we here?" is humanity's most fundamental and persistent question. Tracing the origins of the elements is a direct attempt to answer this at its deepest level. We know many elements are created inside stars and supernovae, ...
Phys.org / Iron-based magnetic material achieves major reduction in core loss
A research team from NIMS, Tohoku University and AIST has developed a new technique for controlling the nanostructures and magnetic domain structures of iron-based soft amorphous ribbons, achieving more than a 50% reduction ...
Phys.org / Shapeshifting gates guard the cell nucleus, challenging old ideas
An international study led by the University of Basel has discovered that nuclear pore complexes—tiny gateways in the nuclear membrane—are not rigid or gel-like as once thought. Their interiors are dynamically organized, ...
Tech Xplore / Audio-augmented wearable aims to improve mindfulness, with possible benefits for those with anxiety and ADHD
A new device uses focused sound cues to keep users grounded amid digital distractions, with possible benefits for anxiety and ADHD as well.
Medical Xpress / Targeted alpha therapy using astatine shows promise in thyroid cancer resistant to conventional treatment
A new targeted alpha therapy is showing promise for patients whose thyroid cancer no longer responds to radioactive iodine, the standard beta-emitting treatment. In a first-in-human study, investigators found that a single ...
Phys.org / Precise catalyst design boosts hydrogen gas production efficiency and affordability
A recent advance in the science of hydrogen fuel production could enable higher output and more sustainable production of this renewable energy source, researchers with Stockholm's KTH Royal Institute of Technology report.
Phys.org / Degraded peatlands emit nearly twice as much greenhouse gas as previously thought, study finds
For the first time, researchers have produced a detailed, high-resolution map of peatlands in the EU, showing that these areas emit twice as much greenhouse gases than previously thought. The research, led by eco-hydrologist ...
