Medical Xpress / Study of 2 million newborns ties skipped vitamin K shot to higher bleeding risk
Newborns receive several routine immunizations shortly after birth. Prophylactic vitamin K is one such recommended shot. It activates several coagulation factors necessary for blood to clot properly, preventing vitamin K ...
Phys.org / Magnetic dopants help quantum dots use light for chemical reactions
Scientists at Los Alamos National Laboratory have demonstrated a new quantum-dot mechanism that could significantly expand the reach of light-driven chemistry. By introducing magnetic manganese dopants into semiconductor ...
Phys.org / Marine microbes point to ancient seawater source beneath Antarctica's Blood Falls
Salty water flowing through Antarctica's Blood Falls contains a distinct community of marine-specific microorganisms, providing evidence that the brine system beneath the glacier has a marine origin, according to a paper ...
Tech Xplore / Solving the solvent problem to make sodium-metal batteries a more practical energy storage option
Lithium-ion batteries are the leading choice in today's electric vehicle and battery energy storage system industries, but they contain a number of critical minerals—including lithium, cobalt, nickel and graphite—that are ...
Medical Xpress / Two women with the same pregnancy complication may face very different risks of premature cardiovascular death
Previous research has shown that women who experience complications during pregnancy face roughly twice the risk of dying prematurely from cardiovascular disease.
Medical Xpress / How age shapes treatment decisions in chronic coronary disease
For many older adults with heart disease, age is a significant factor in treatment decisions. But a new Yale–led study published in the Journal of the American Geriatrics Society suggests that overall health, function and ...
Medical Xpress / Testing is underway on vaccines to intercept brewing colon cancer before it takes root
Dr. Stacy Norton was only 7 years old when her mother died of colon cancer, one of several family members struck by aggressive tumors at unusually young ages. Decades later, Norton rolled up her sleeve to help test if a new ...
Medical Xpress / The human side of robotic surgery: Tracking surgeons' stress in the operating room
Robot-assisted surgery (RAS) is one of the most advanced tools in modern medicine. These systems give surgeons extreme precision, allowing procedures to be performed through small incisions that minimize both pain and recovery ...
Phys.org / Improving oats for growers and consumers
Heart-healthy oats are finding their way into a wider variety of products and recipes as consumer demand grows. Although oats are grown on far fewer acres than other U.S. crops, farmers are able to keep up with demand through ...
Tech Xplore / Heat treatment improves strength-ductility balance of 3D-printed aluminum bronze for electronic components
Researchers from Skoltech—a VEB.RF group institution—and their colleagues from State Marine Technical University and others have found a way to improve the balance between the mechanical strength and ductility of 3D-printed ...
Medical Xpress / Fewer heart attacks, more cancer cases, and better survival chances: The effectiveness of disease prevention
Medical progress is currently one of the strongest forces shaping populations and their health. For instance, an acute heart attack has evolved from being nearly always fatal in the past to having a much higher survival rate ...
Phys.org / New photonic platform offers a four-lane highway for light
Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this ...
