For patients living far from hospitals with balloon treatment facilities, emergency medical personnel must be educated to perform and transmit ECGs to ensure proper referral.
Prapiroon, a large and powerful storm in the western North Pacific, has transitioned into an extra-tropical cyclone. The storm is expected to weaken over the next few days, eventually fading away from view.
Researchers at Simon Fraser University have discovered a Trojan horse-like mechanism that enables antibiotics to deliver directly into a bacterial cell. The method uses pilus filaments to transport antibiotics into bacteria, offering a new approach to treat deadly bacterial infections like cholera and Pseudomonas aeruginosa.
A bi-national study reveals significant increases in social problems, rule breaking, and aggressive behavior among children living in poverty on the US-Mexico border. The study highlights the need to address mental health concerns to prevent long-term devastating effects on families, communities, and individuals.
Researchers at the University of Veterinary Medicine in Vienna used fruit flies to study adaptation to changing temperatures, finding temporally heterogeneous trajectories of selected alleles. Genetic changes were widespread and rapid, with some genes adapting quickly while others showed little change.
Researchers from Aalto University successfully fabricated complex three-dimensional structures at the nanoscale by combining ion processing and nanolithography. The discovery unlocks new possibilities for nanofabrication, with potential applications in device manufacturing.
Scientists have conducted the first range-wide genetic analysis of bowhead whales using ancient DNA samples from archaeological sites and modern populations. The study reveals differences in population diversity between ancient and modern times, suggesting recent disappearance of unique maternal lineages due to habitat loss and whaling.
A new UGA study finds that national recession affects travel to national parks, with decreases in visitation since 1998. Despite this, some parks experience notable increases due to international recognition.
INRS is launching two new nanotech labs focused on neurotechnology and nanobiophotonics. The labs will support research in emerging fields with high potential for future innovations in health and information technology.
Research at IDWeek 2012 reveals high rates of HIV medication errors in hospitalized patients, but studies suggest that combining electronic records with clinical education can significantly decrease errors. Hospitals are implementing quality improvement measures to address the issue.
Salk scientists pinpointed damage to neural stem cells, specifically deformed nuclear envelopes, leading to neuronal loss and dysfunction in Parkinson's patients. The discovery may lead to new diagnostic and therapeutic approaches, including targeted gene-editing technologies.
Children's hospital admissions for acute throat infections increased by 76% between 1999 and 2010, according to new research. The study found that short hospital stays accounted for the majority of admissions, but suggested that improved healthcare access could reduce unnecessary hospitalizations.
