Researchers analyzed seismic activity from six stations in West Antarctica, discovering a significant number of small earthquakes. The study confirms that West Antarctica is prone to earthquakes due to its rift-like nature.
A new climate study found that glaciers in the tropical Andes Mountains retreated several thousand years earlier than North American glaciers during a period of wet climate conditions. The research contradicts traditional thinking on global glaciation and suggests an alternative trigger for climate change.
A team of researchers is testing a new hyperspectral sampling technique to identify expansive clays in Colorado construction sites. The method, developed from NASA analysis techniques, aims to reduce remediation costs and prevent damage caused by swelling soils.
The American College of Emergency Physicians has issued first consensus guidelines on lightning safety before summer storms. These guidelines emphasize the importance of individual responsibility in avoiding lightning injury and provide tips on safer practices, including knowing safe locations and following weather updates.
A UNC research team has shed new light on the classic 'lock-and-key' theory of drug action by discovering functional selectivity. The findings reveal that drugs can act as both agonists and antagonists at different receptors, allowing for more targeted treatment options. This breakthrough could lead to improved clinical effects with ex...
Duke University researchers have successfully transformed adult stem cells taken from fat into cells that resemble nerve cells. The new cells were grown in the laboratory using chemicals and growth factors, and showed promise as a potential treatment for central nervous system disorders. While further research is needed to determine th...
Researchers found that glaciers in the tropical Andes Mountains retreated several thousand years earlier than North American glaciers during a wet period, indicating temperature change was the primary cause of glacial retreat. This challenges conventional wisdom that high northern latitudes drive global climate change.
Researchers studied monkey behavior in a task that simulates goal-driven actions, revealing a boost in brain signal as the reward neared. The signal is thought to sustain goal-directed behavior and may underlie abnormal activity in the brain area associated with obsessive-compulsive disorder.
Researchers found two genes associated with human cancer play a central role in orienting cells towards chemical cues. They discovered that PI3K acts as an internal compass and steering mechanism, allowing cells to move efficiently towards chemical attractants.
Epilepsy does not increase motor vehicle crash risks compared to other medical conditions; regulations hinder patients from seeking proper care. Mandatory reporting laws are discriminatory and destroy patient-physician confidentiality.
Organic farming methods produced 20% smaller crop yields compared to conventional farming, but made up for it in ecological benefits. The study found that organic soils were more fertile, had a larger community of organisms, and decomposed more efficiently.
A recent study by Dr. Mark S. Kaplan and colleagues found that regular physician visits and dental check-ups are strongly associated with lower rates of smoking among older adults. The study analyzed data from the Canadian National Population Health Survey, which surveyed over 73,000 households across Canada.
A national survey found that most adults are unaware of the effectiveness of policies like raising taxes on alcoholic beverages and increasing the drinking age. Effective measures have saved tens of thousands of lives, but public awareness is needed to prevent accidents.
A team of Johns Hopkins University students designed and built a muscle enhancement device that enables a disabled man to grasp and lift small objects. The device uses two motors, voice recognition software, and an exo-skeleton inspired by science fiction to provide mechanical help in moving the man's fingers and bending his elbow.
A study found that homeless sexual minority youth are more likely to experience physical and sexual abuse, with bisexual individuals reporting the most incidents. These young people face significant challenges in their lives, including heavy substance abuse and difficulties dealing with their sexual identity.
Researchers aim to develop autonomous intelligent network and systems that can perform coordinated actions without human intervention. The goal is to create a 'commander' giving broad operational orders, while agents work together to overcome complex challenges, such as distributed signal processing and wireless communication.
Gardner's book examines how contemporary writers are expanding and testing the idea of 'fallen poetics' explored by Dickinson. The author analyzes works by Robinson, Graham, Wright, and Howe, among others, to understand their responses to human limits and the opening out of human responsiveness.
A new diagnostic faecal test detected MCM2-positive cells in 37 of 40 patients known to have colorectal cancer, but not in healthy individuals. The findings suggest that the test could be suitable for population screening, either alone or in combination with other tests.
PTEN, a cancer-suppressing protein, directs cells by anchoring to the cell membrane and regulating phosphate groups. Its presence helps cells move forward while restricting movement at the back, crucial for sensing direction. The findings could have implications in understanding cancer spread and metastasis.
The Lancet's editor urges caution on expanding nurse prescribing rights in the UK, citing concerns over inadequate training and potential risks to patient care. The government's plan to extend prescribing powers to all nurses is criticized for its haste and lack of regard for nursing professional boundaries.
A field study in Zimbabwe found that younger women formed partnerships with men 5-10 years older, increasing their risk of HIV-1 infection. Younger women also reported fewer condom uses and more frequent sexual activity, further exacerbating the issue.
Dr. McConnell's groundbreaking work on cellular behavior at the molecular level has shed light on interactions between cholesterol and phospholipids, as well as protein-peptide reactions. His research aims to improve understanding of immune surveillance and cholesterol function in cells.
The Marsquake sensors will detect weight shuddering caused by liquid water beneath the Martian equator, pinpointing each quake's location. This new method will help scientists find life on Mars and shed light on the planet's internal structure.
A large international trial found that magnesium sulphate reduced the risk of eclampsia by over half and maternal death by 45% compared to placebo. The treatment was also associated with a lower incidence of side effects.
Researchers at Baylor College of Medicine found that the CA3 region of the hippocampus is essential for 'pattern completion', allowing memories to be recalled from partial representations. The study involved genetically engineered mice with impaired NMDA receptor function in the CA3 region, which displayed deficits in memory recall.
Scientists have observed glowing coral reefs when illuminated with blue light, which could be used to map specific coral groups within a reef. This phenomenon is related to species and coral health, providing a potential tool for managing sensitive military areas and detecting man-made objects.
A team of scientists led by Indiana University's Alan Kostelecky aims to determine if Albert Einstein's theory of relativity holds true. By comparing extremely precise clocks in zero gravity, they may find changes that contradict the theory, revolutionizing our understanding of space and time.
QuikClot is a granulated material that rapidly absorbs all liquid in the blood and leaves behind clotting factors to effect coagulation within seconds. The product has been cleared by the FDA and is being distributed to US troops in Afghanistan, with plans for wider use in military and civilian settings.
Leaders in emergency medicine will read the same articles to share a common knowledge and background, with annual self-assessment tests to prove mastery of medical literature. The requirement aims to improve patient safety and physician accountability, as mandated by the American Board of Medical Specialties.
A team of scientists discovered a brain signal that encourages us to continue working on tasks to receive rewards. Abnormal activity in this signal may contribute to conditions like obsessive-compulsive disorder or drug abuse.
A study found that elderly patients with multiple prescription medications have difficulty identifying them, dosages, frequencies, and indications. The study suggests that this issue may be more widespread among elderly patients who are disoriented or medically unstable.
