Australian and South African sites selected as top contenders to host the Square Kilometre Array (SKA) radio telescope, with low man-made signals a key requirement. Both countries' sites offer stable ionospheric conditions and a good view of the southern sky, ideal for detecting cosmic radio waves.
Researchers at NIST have measured the Einstein-de Haas effect in a ferromagnetic thin film, shedding light on magnetization dynamics and g-factor calculations. The study provides a proof-of-concept for using this effect to determine critical material properties for data storage and spintronics applications.
International experts issue checklists to address the interests of the world's most disadvantaged during a pandemic. The Bellagio Statement of Principles aims to improve public health planning and response with the needs of poor groups in mind.
The HLPR Chair system provides powered mobility and allows patients to move to and from beds, chairs, and toilets without assistance. It reduces caregiver and patient injuries through its lifting ability and center of gravity management.
New NIST study reveals portable radios can't withstand high-temp fires without protective gear, posing communication risks to firefighters. Radios inside pockets or gear fared better, but exposed components failed quickly.
A study conducted at the University of California, Davis found that contrast-enhanced sonography accurately depicted 91% of liver, spleen, or renal injuries, outperforming non-contrast enhanced sonography.
A new study has discovered that people with tone deafness lack white matter in the right inferior frontal gyrus, a key area for musical skills. The findings have implications for understanding normal music acquisition and diagnosing this lifelong disability.
A Georgetown University researcher warns of a growing epidemic of hookah smoking, citing equivalent toxic effects to cigarette smoking and a disproportionate impact on young women. Studies show that waterpipe tobacco smoke can penetrate deeper into the respiratory tract than cigarette smoke, increasing cancer risk.
A new study by Queen's University biologist Virginia Walker has discovered a way to isolate bacteria that can create better ice cream and artificial snow from soil in more temperate environments. The technique, called ice affinity selection, involves forming an 'ice finger' to select for bacteria that gather on the surface of ice.
A recent study found that adults infected with the common cold virus easily transferred the virus to 35% of surfaces touched, and even to an uninfected person by fingertips 18 hours after initial contamination. The virus was also found on a third of objects and surfaces in hotel rooms.
Researchers have identified a protein, STM3117, that helps Salmonella evade immune cells, allowing the bacteria to multiply inside macrophages. The discovery presents a promising target for developing new drugs, vaccines, and rapid diagnostics to combat food poisoning caused by Salmonella.
Researchers discovered that a dissolved form of manganese can keep toxic hydrogen sulfide zones in check by reacting with oxygen and hydrogen sulfide. This finding alters the understanding of manganese aqueous geochemistry and has implications for waterways like the Black Sea and Chesapeake Bay.
Researchers found that adults infected with rhinovirus, the cause of half of all colds, can contaminate hotel room objects, leaving an infectious gift for others. The study, conducted in hotel rooms, shows that viruses can survive on surfaces for at least a day.
A population-based surveillance study found that treatment with Tamiflu (oseltamivir) significantly reduced mortality from seasonal influenza in severely ill adults. The study, conducted in Ontario, Canada, showed a 71% reduction in death from influenza among treated patients.
The Iraqi public demonstrates the highest levels of intolerance to foreigners, with extraordinarily high levels of ethnic solidarity. Despite this, a majority of Iraqis (85%) believe democracy is the best form of government and their commitment seems genuine.
A new study by the American Academy of Family Physicians recommends a 39% increase in family physicians to address the growing health care needs of Americans. The report asserts that without reform, millions will struggle to access high-quality primary care.
Researchers at UGA have discovered a species-specific cell-wall carbohydrate in B. anthracis, making it an important target for diagnostic tests and potential vaccine additives. The molecule's unique structure could help develop new vaccines and diagnostics to combat anthrax.
The efficacy of AVELOX in treating complicated intra-abdominal infections was highlighted at ICAAC. The study showed that once-daily AVELOX monotherapy was as effective as combination therapy, with overall clinical cure rates of 80.9% and comparable duration of therapy.
The Living While Black index combines economic, social, and health factors to assess the quality of life for African Americans. Religiosity serves as a buffer, reducing the impact of stressors. Economic factors like poverty rates and business sales negatively affect quality of life.
A study found that patients who exercised prior to hip and knee replacement required significantly less inpatient rehabilitation, walking more than 50 feet at discharge. The exercise program improved lower-extremity muscle strength and function before and after surgery.
A new study published in Arthritis Care & Research found that weight training did not improve knee strength in patients with osteoarthritis, but may slow progression of joint space narrowing on X-rays. Patients who participated in strength training showed less joint space narrowing than those in a range-of-motion regimen.
Duke University researchers developed a computer model to predict the effectiveness of various microbicidal recipes in destroying HIV before it reaches body tissues. The study found that a thin coating of microbicide delivered to the vagina can significantly reduce HIV transmission.
Researchers analyzed nine trials involving 693 patients and found that treatment with calcium-channel blockers or alpha blockers increased the chances of passing urinary stones by 65%, making these medications an effective alternative to surgery.
A large collaborative effort has made publicly available genetic data for Parkinson's research, providing new opportunities for future studies. The data includes genotypes from hundred of patients and healthy controls, which may help identify common genetic variability that results in minor and moderate risk for disease.
Government laboratories can quickly analyze radioactive samples but with variable accuracy and quality control procedures. The NIST tests found that measurement capability is generally accurate within 30% of the expected value.
A McGill University study found no difference in time for men and women to reach peak arousal, contrary to previous assumptions. The use of thermal imaging technology allows for minimally invasive measurement of sexual arousal rates.
Women under 45 who have both ovaries removed are at higher risk of death from hormone-related cancers and neurological diseases. The risk increases with age, suggesting that oestrogen may be protective at younger ages but less important after menopause.
A University of Rochester study found that African Americans and Latinos are more likely to over-report their last preventive screening test, potentially harming their health. The research highlights the need for accurate tracking of ethnic disparities in healthcare.
