Phys.org / A new role for DNA loops in repairing genetic damage
When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its DNA structure to speed ...
Medical Xpress / Kennedy's vaccine advisory committee delays vote on hepatitis B shots for newborns
A federal vaccine advisory committee on Thursday voted to delay a decision on whether newborns should still get the hepatitis B vaccine on the day they're born.
Tech Xplore / Scientists develop a glasses-free 3D system with a little help from AI
Watching 3D movies and TV shows is a fun and exciting experience, where images leap out of the screen. To get this effect, you usually have to wear a special pair of glasses. But that could soon be a thing of the past as ...
Tech Xplore / Zinc-ion batteries get a boost from protective film that reduces dendrite formation
While burning electric vehicles, exploding e-bikes and melting smartphones no longer make the headlines, the issue of battery safety has yet to be fully resolved. To address this, UBC researchers recently made a crucial breakthrough ...
Phys.org / Earlier ultra-relativistic freeze-out could revive a decades-old theory for dark matter
A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from Standard Model particles far earlier than previous theories had suggested.
Phys.org / Research reveals atypical Santas can succeed
A naturally fluffy white beard, a round belly and a jolly laugh might seem like the keys to being a successful Santa Claus, but new research suggests that a calling to play the man with the bag full of toys is enough to help ...
Medical Xpress / New organ-on-a-chip platform allows the testing of cancer vaccine efficacy in aging populations
Dr. Vadim Jucaud's lab at the Terasaki Institute has introduced a new organ-on-a-chip platform that recapitulates age-dependent immune responses, offering a more accurate testing bed for evaluating cancer vaccine performance ...
Medical Xpress / Rapid, low-cost tests can help prevent child deaths from contaminated medicinal syrups
Researchers at the University of Oxford and their collaborators have demonstrated that simple, rapid, and inexpensive tests can detect deadly contaminants in medicinal syrups—contaminants that have tragically led to the ...
Phys.org / Hydrogel platform enables high-throughput extracellular vesicle isolation
Extracellular vesicles (EVs) have rapidly emerged as one of the most promising frontiers in modern biology. These nano-sized messengers mediate communication between cells, tissues, and organs, influencing processes from ...
Phys.org / Human hair grows through 'pulling' not pushing, study shows
Scientists have found that human hair growth does not grow by being pushed out of the root; it's actually pulled upward by a force associated with a hidden network of moving cells. The findings challenge decades of textbook ...
Phys.org / Silver nanoparticles built on viral biotemplate kill more bacteria and slow resistance rise
Antibiotics are no longer able to treat infections as effectively as they once did because many pathogens have developed resistance to these drugs. This phenomenon, known as antimicrobial resistance (AMR), claims over a million ...
Medical Xpress / Modified herpes virus helps destroy glioblastoma in preclinical models
Researchers at Mass General Brigham have modified a herpes simplex virus (HSV-1) that stimulates the immune system to attack glioblastoma cells. A single dose of the modified virus increased T-cell, natural killer cell, and ...
