Researchers have developed a new method to detect potential tropical cyclones using satellite data, allowing for earlier warning times of up to 40 hours. This technique uses wind speed data from the SeaWinds scatterometer on NASA's QuikSCAT satellite to identify areas of rotating winds.
A study in Annals of Internal Medicine finds that accurate profiling of physician care depends on study design, and that most quality initiatives fail to adjust for patient characteristics. Additionally, researchers estimate that colonoscopy is a cost-effective strategy for investigating rectal bleeding in young people
A team of UCLA and Finnish scientists has identified a genetic mutation outside the lactose intolerance gene, found in 196 adults from African, Asian, and European descent. The researchers believe this variant is the original form of the gene that mutated to tolerate milk products when humans adopted dairy farming.
Patient participation is limited in teleconsultations due to restricted talk time and lack of opportunity for patients to ask questions or assert their opinions. However, incorporating partnership-building methods like asking for patient's opinion can increase patient involvement and improve diagnosis, treatment, and health improvement.
A new study by University of Michigan researchers finds that JCAHO hospital accreditation does not correlate with patient outcomes, highlighting the need to review the current system for ensuring quality in US hospitals. The study also suggests that the JCAHO system prioritizes structural measures over newer performance metrics.
Researchers found that regular use of aspirin cuts coronary heart disease risk by 28% in people at heightened risk. Doctors should discuss pros and cons with patients to determine individualized decision, considering age, habits, and medical histories.
A new NASA-funded study shows that global warming in recent decades has been caused by carbon dioxide, with other greenhouse gases including methane, tropospheric ozone, and black carbon. The growth of emissions has slowed over the past 20 years, primarily due to the phase-out of ozone-depleting gases.
A study by the Johns Hopkins Bloomberg School of Public Health found that safety counseling coupled with convenient access to reduced-cost products increased parents' safety practices. The combination of pediatric counseling and visits to a children's safety center was successful in increasing safety practices, while home visiting prog...
Researchers at Rensselaer Polytechnic Institute have developed a new terahertz imaging technique that allows for faster and more detailed imaging of biological tissue. The technique uses single pulses of terahertz radiation to produce high-resolution images with the potential to automate diagnostic analysis.
A new study from Ohio State University found that nearly a quarter of LASIK patients experience nighttime vision problems, including halos, starbursts, and glare. These symptoms may persist long after the eye heals and are linked to factors such as having had the surgery repeated or having flatter corneas at the outset.
A University of Houston researcher developed a biodegradation test to ensure synthetic-based drilling fluids are environmentally safe. The EPA guideline reduces pollution by seven million pounds annually, saving operating costs without economic impacts.
A strong patient-physician relationship is crucial to obtaining needed health services, the study found. Primary care systems that prioritize accessibility, coordination, and comprehensive care can lead to stronger relationships between patients and physicians, ultimately improving health outcomes.
A research team led by William Laurance found that Amazonian forest destruction rates have risen sharply since 1995, contrary to the Brazilian government's claims. Deforestation has increased due to infrastructure projects and expanding logging and mining industries.
The USPSTF recommends discussing aspirin therapy with adult patients at increased risk of coronary heart disease, such as those with unfavorable cholesterol levels, smoking, or hypertension. Aspirin may help prevent heart attacks in these individuals, but its benefits and harms should be carefully weighed.
A recent study found that having two copies of a less-common version of the klotho gene is linked to a shorter lifespan in infants, while one copy may be associated with a longer life in older adults. The researchers also discovered that the variant is relatively common across different ethnic populations.
A team led by Tom Murphy will use laser ranging and a large telescope to measure the moon's distance from Earth with accuracy of a millimeter. The project will also test Einstein's equivalence principle and the strength of gravitational interaction, providing insights into gravity's nature.
