Medical Xpress / Single saRNA shot helps with healing after a heart attack
For people who have survived a heart attack, the notion of one shot in the arm to help the heart heal, for weeks after, may seem far-fetched. But thanks to a team of researchers, including a Texas A&M University professor, ...
Phys.org / Researchers thought inbred koalas were at risk of extinction—what they discovered upends genetic conventions
If you follow media coverage of koalas, you could be forgiven for feeling confused. Recent stories describe a "koala paradox": endangered in the north of Australia, abundant in the south; genetically diverse in some regions, ...
Phys.org / Real-time imaging of microplastics in the body improves understanding of health risks
Microplastics (MPs), defined as plastic fragments with sizes ranging from millimeters (
Medical Xpress / Brain-clearing cells offer clues to slowing Alzheimer's disease progression
Accumulation of the protein tau in the brain is one of the hallmarks of Alzheimer's disease. In a paper published in Cell Press Blue, researchers report a previously unknown mechanism that appears to enable the buildup of ...
Phys.org / Flipped chromosomal segments drive natural selection, Atlantic silversides study shows
When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits. But what about mobile aquatic species ...
Medical Xpress / Learning makes brain cells work together, not apart
When you get better at a skill—recognizing a familiar face in a crowd, spotting a typo at a glance, or anticipating the next move in a game—sensory neurons in your brain become more coordinated, sharing information rather ...
Medical Xpress / Scientists engineer 'living eye drop' to support corneal healing
University of Pittsburgh School of Medicine researchers have developed an early-stage, experimental "living eye drop" that uses naturally occurring eye bacteria to support corneal wound healing. The proof-of-concept study, ...
Phys.org / Paleontologists challenge use of bone growth rings to age crocodiles, dinosaurs
Do the bones of all Nile crocodiles have the same number of growth marks as their age? And can such growth rings be counted to accurately gauge the age of these reptiles? Is this also an accurate method to use when trying ...
Phys.org / Environmental sampling finds more poultry viruses than bird swabs in live markets
Scientists at Duke-NUS Medical School have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study, published ...
Medical Xpress / Overcoming ovarian cancer's resistance to immunotherapy
Cells in our immune system are best known for providing security against external invaders such as bacteria and viruses. These immune cells also guard against internal threats, including cancerous tumors. Different forms ...
Phys.org / 3D imagery helps bring world's ant diversity to life
For more than a decade, Evan Economo's lab has been using micro-CT machines to scan insect specimens. The resulting X-ray images help researchers study the form and structure of insects—a subfield of entomology known as ...
Phys.org / Fluorescent imaging reveals how a global parasite develops, opening new paths for drug treatment
It infects nearly one-third of the global population, yet its microscopic size makes the parasite difficult for scientists to study. That parasite is Toxoplasma gondii, a widespread organism that infects humans and animals. ...
