Phys.org / Why warmer seas may not wipe out female fish in some species
In many fish species, water temperature determines the sex of the fry. This biological mechanism threatens to wipe out entire populations because of a shortage of females in the face of global warming. However, an international ...
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 / Discovery of how cells maintain their DNA could shield key healthy cells from chemotherapy side effects
A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which cells chemotherapies target. ...
Phys.org / Four-decade mystery solved as PKCβ structure reveals new drug target
After nearly four decades of research, Mayo Clinic scientists have revealed the molecular structure of protein kinase C beta (PKCβ), a key protein linked to cancer and neurological diseases. The findings, published in Nature ...
Phys.org / New AI tool identifies wild animals by their unique patterns in real time
Patterns reveal the individual: A novel AI algorithm equips researchers with a powerful new tool to accurately identify individual jaguars, zebras and giraffes in real time based on their unique coat patterns. Biologists ...
Phys.org / Controlling ice crystal growth using polymer nanoparticles
Ice formation can damage biological samples, tissues and materials during freezing and thawing. In nature, specialized molecules known as ice-binding proteins prevent ice crystals from growing too large, helping organisms ...
Phys.org / Plant protein pair reveals new wood-formation mechanism
Researchers from the Biosciences Department at Durham University have discovered a previously unknown mechanism that helps plants control the formation of wood, a finding that could open new directions for research into plant ...
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 / DNA loops reveal how immune cells build millions of antibodies from one genome
How does your body produce millions of antibodies from one genome? New research reveals how two closely related proteins help immune cells fold DNA, connecting distant genetic pieces to create diverse antibodies that help ...
Phys.org / Symbiotic partner-swapping or long-term fidelity? Partnership success between beetles and bacteria revealed
Some insects and microbes develop symbiotic partnerships that become so interdependent they can no longer survive without each other. But how specific are these heritable symbioses? Is it possible for the same species of ...
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.
