Phys.org / Light switch for life: Controlling molecular droplets with UV
Biomolecular condensates are tiny, droplet-like structures made up of molecules that help organize key processes in living organisms. Because they are so small and constantly changing, it has been difficult for scientists ...
Medical Xpress / Turning muscles into motors gives static organs new life
What if a technology could reanimate parts of the body that have lost their connection to the brain—like a bladder that can no longer empty due to a spinal cord injury, or intestines that can't push food forward due to Crohn's ...
Medical Xpress / A state policy required hospitals to offer more financial assistance—medical debt plummeted
A policy in Oregon that requires nonprofit hospitals to provide more financial assistance to patients was linked to a meaningful drop in the number of residents with medical bills that end up in debt collections, according ...
Phys.org / Wildlife-friendly landscapes dramatically boost biodiversity in fragmented forests, research reveals
A new study has revealed that improving the landscapes surrounding forest remnants can dramatically increase their ability to retain bird species—even when the forest fragments themselves are small or isolated. For decades, ...
Medical Xpress / Health literacy initiative improves discharge education, readmission rates
Assessing health literacy levels soon after hospital admission and adjusting discharge instructions accordingly helped reduce readmission rates for pediatric patients after heart surgery and improve caregiver satisfaction ...
Phys.org / Seals use whisker movement to follow underwater trails—an approach that could improve robotic sensing
Seals are carnivorous marine mammals that are well adapted to hunting for fish underwater, where visibility is poor. In such conditions, seals rely on their highly sensitive whiskers to detect tiny water movements left behind ...
Phys.org / Study explains Antarctic sea ice growth and sudden decline
A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica.
Phys.org / Queen bumblebees can breathe underwater for days. We discovered how
In most bumblebee species, the queens spend their winters buried underground in a tiny cavity the size of a grape. For six to nine months, they enter a deep sleep-like state called diapause, waiting for spring.
Phys.org / Bacteria invent another way to turn on genes
In their landmark 1961 paper on the lac operon, Nobel laureates François Jacob and Jacques Monod speculated that RNA might control gene activity in bacteria through base-pairing interactions. But once protein transcription ...
Phys.org / Tracing the evolutionary history of chemical warfare between plants and insects
A new study published in Nature Ecology & Evolution connects plant and insect physiology, chemical ecology, molecular function, and evolutionary analysis to offer a new perspective on plant–insect coevolution. The research ...
Medical Xpress / Dangers of 'anti-aging' supplements in cancer protection revealed
Millions of Americans take daily supplements—nicotinamide mononucleotide (NMN), nicotinamide riboside (NR) and nicotinamide (NAM)—to boost energy, slow aging and protect the heart and brain. Many cancer patients also take ...
Phys.org / Why some predators thrive near people: A Kenya hyena study highlights tolerance
Human–wildlife coexistence is often far from straightforward, with predators particularly hard hit: their numbers tend to fall sharply in areas close to human settlements, fields and pastureland. This is not, however, a simple ...
