Medical Xpress / Patients with atrial fibrillation face higher bleeding risks when treated with 2 common medications
Patients with atrial fibrillation who are prescribed diltiazem to control heart rate alongside anticoagulants (blood thinners) such as apixaban or rivaroxaban face a higher risk of serious bleeding compared with those taking ...
Medical Xpress / Neurosurgeons are really good at removing brain tumors—they're about to get even better
When removing cancerous tissue in the brain, neurosurgeons often use "awake brain mapping" to minimize the risk of causing unintended disruptions to a patient's quality of life while removing as much tumor as possible. This ...
Phys.org / Canada's Magdalen Islands' peatlands hold vital clues about ancient Atlantic hurricanes
Eastern Canada has seen a rise in the number of hurricane- and near-hurricane strength events battering its maritime areas, with particularly violent storms in 2003 (Hurricane Juan), 2019 (Dorian) and 2022 (Fiona). While ...
Phys.org / Bacterial pathogens build antibiotic-resistant 'bunkers' using filament scaffolds
Researchers have discovered and characterized at the atomic level a mechanism that enables bacterial pathogens—including hospital bacteria Acinetobacter baumannii and Pseudomonas aeruginosa—to assemble antibiotic-resistant ...
Phys.org / This mysterious protein punctures our cells—now researchers know how
The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's systems in balance. A new ...
Phys.org / Enzymes work as 'Maxwell's demon' by using memory stored as motion
Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and function. Enzymes play a central role in this process, accelerating reactions that would otherwise ...
Tech Xplore / Water-based enzyme ink enables one-step printing of wearable biofuel cells
Enzymatic biofuel cells can act as self-powered wearable biosensors by converting chemicals in body fluids into electricity; however, manufacturing challenges have prevented their widespread adoption. Now, researchers from ...
Phys.org / Heat relief means higher emissions: How air conditioning complicates 1.5°C goals
While air conditioning protects people from dangerous heat, it also significantly worsens global warming—by 2050, potentially producing more carbon dioxide than the current annual emissions of the United States, a new study ...
Phys.org / E-waste chemicals are appearing in dolphins and porpoises
Liquid crystal monomers (LCMs) are critical components of laptop, television, and smartphone screens. Given their ubiquity in the environment, these compounds are considered persistent pollutants, posing threats to marine ...
Phys.org / New lab technique can reverse chemical process linked with Alzheimer's disease
An Oregon State University scientist and a team of undergraduate students have uncovered real-time insights into a chemical process linked with Alzheimer's disease, paving the way toward better drug designs. The researchers ...
Medical Xpress / Differing immune responses in infants may explain increased severity of RSV over SARS-CoV-2
Young infants hospitalized with respiratory syncytial virus (RSV) often become much sicker than those infected with SARS-CoV-2, the virus that causes COVID-19. In a study published in Science Translational Medicine, scientists ...
Phys.org / Surprise solar eruptions on sun's far side validate new forecasting method
A team of scientists from around the world has created the first system that can predict when and where extremely powerful solar storms, called superflares, are most likely to happen. These storms can disrupt power grids, ...
