Phys.org / Next-generation pesticide disrupts bumblebee reproduction
Bumblebees are only an inch long, but they help power the global food system. Roughly one-third of the food we grow depends on pollinators like bees—and those bees are regularly decimated by pesticides.
Phys.org / How sperm whale vocal dialects evolve as they adopt new calls while still remembering the old
New research from the University of St. Andrews shows how sperm whale vocal dialects evolve as they adopt new calls while still remembering the old. An international team of researchers studying vocal dialects in the endangered ...
Phys.org / Amazon fish reveal a synchronized survival tactic that could transfer to drone swarms
Some fish swim in synchrony. Others, it turns out, breathe in synchrony. This is true for arapaimas, an obligate air-breathing species living in the Amazon. A new study in Communications Biology, led by the Leibniz Institute ...
Phys.org / How continental shelf seiches triggered flooding following New York and New Jersey hurricanes
In 1938 and 1944, two major hurricanes struck Long Island, and after the initial winds subsided, the surges came back unexpectedly hours later, leading observers to wonder whether this was a tsunami. In a study appearing ...
Dialog / Liquid ripples rewrite 130-year-old biological classic: New reflections on the lock-and-key model
This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil Geissler. A legendary physical ...
Phys.org / Researchers find microplastics in hedgehogs—then trace them back to pet food
When colleagues and I found microplastics in hedgehog droppings, we wanted to know where they were coming from. One answer was surprisingly close to home: pet food.
Phys.org / New energy-boosting quantum mechanism discovered in photosynthetic bacteria
Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their efficiency when capturing sunlight. The study, published today in the journal Nature Chemistry and led ...
Phys.org / Nanoparticles sneak antibodies into cells to inhibit cancer and inflammation
A delivery system that uses lipid nanoparticles to sneak proteins into cells can accomplish the same feat by smuggling therapeutic antibodies, new research has found.
Phys.org / Although woodland salamanders have looked the same for millions of years, their physiology has evolved rapidly
For her doctoral dissertation, Yale's Nathalie Alomar decided to study a small amphibian that appeared to have eluded the forces of evolution. She found that there is more to its evolution than meets the eye.
Phys.org / Chloroplast study reveals molecular lock that helps power life on Earth
A new study reveals the dynamics of photosynthesis at the cellular level. Led by co-authors Professor Barry Bruce and Associate Professor Rajan Lamichhane, both of the Department of Biochemistry and Cellular and Molecular ...
Phys.org / Contact lenses can repair themselves with just one hour of UV light exposure
Contact lenses are a great vision correction option for many, but if one of them gets damaged, there is little to do other than throw it away. A team reporting in ACS Applied Polymer Materials has a solution: special polymer ...
Phys.org / Honeybee metamorphosis map uncovers 842 active DNA switches that drive worker bee development
Researchers have identified "DNA switches" that become active as honeybee larvae grow into worker bees, offering new insight into the development of these important pollinators and the ecosystems they support.
