Medical Xpress / Teen digital overuse reflects distinct psychosocial profiles, study finds
When a teenager spends hours in front of a screen, parents and clinicians often reach the same conclusion: too much technology. However, a new study suggests that the type and meaning of digital engagement may differ substantially ...
Phys.org / Twisted laser light distinguishes mirror-image molecules by their fragment counts
Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers ...
Medical Xpress / Experimental plague vaccine strategy protects mice with missing key immune defenses
The plague has killed more people than World War II. The bacterium Yersinia pestis (Yp), which causes plague, has triggered three major pandemics throughout history, leaving behind a casualty toll of more than 200 million ...
Medical Xpress / Two decades of Medicare payment cuts associated with growing barriers to patient care
A new study from the Harvey L. Neiman Health Policy Institute found that persistent declines in Medicare physician reimbursement are associated with widening disparities in access to care, with patients in rural communities, ...
Phys.org / New snail species bolster case for protecting Montenegro's biodiversity
The descriptions of the two new additions to the European snail fauna, named Cochlostoma komarnica and Cochlostoma dobrido, have been published in the open-access Biodiversity Data Journal.
Phys.org / Inverse-designed 2D magnonic crystals widen spin-wave band gaps
Spin waves (SWs), or magnons, are collective excitations of magnetization in magnetic materials arising from electron spins. They have attracted considerable attention as information carriers and have shown promise in logic ...
Phys.org / Biomolecular condensates reveal surprising activity as catalysts
Biomolecular condensates are ubiquitous in living cells, including bacteria, viruses, plants and mammalian systems. These membraneless bodies, or molecular communities made up of DNA, RNA and proteins, are where molecules ...
Phys.org / Plants know when to grow—and when to hold back, study finds
Researchers have uncovered a surprising mechanism that allows plants to carefully coordinate the formation and growth of new leaf parts. The study shows that the hormone auxin regulates different phases in organ formation ...
Medical Xpress / Circadian gene variants offer new indicator of obesity risk in children
New research from the Guelph Family Health Study (GFHS) has found that circadian rhythm-related genes could influence the risk of obesity in children, highlighting an important connection between sleep and eating behavior.
Phys.org / JWST captures rare glimpse of early black hole growing inside network of young galaxies
Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion ...
Medical Xpress / New study reveals how blood cancers outsmart BTK-targeted therapies
Scientists at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, and collaborators have uncovered a rare genetic mutation that enables some blood cancers to evade both approved ...
Medical Xpress / Scientists develop a two-step system for detecting and classifying brain tumors from MRI images
Researchers have developed a new artificial intelligence-based method that could significantly improve the detection and classification of brain tumors from MRI scans, achieving higher accuracy than conventional diagnostic ...
