The discovery resolves a decades-long debate over the village's location and sheds light on the life of Louis Chatellereau, a French farmer and fur trader.
A study by Northwestern University researchers found that men who smoke are more likely to experience erectile dysfunction due to the negative effects of smoking on blood vessels. The prevalence of erectile dysfunction in former smokers was similar to that of never-smokers, highlighting the long-term risks of tobacco use.
Researchers suggest a structured intermittent therapy approach, where patients receive daily doses of HAART for seven days, followed by seven days off the medication. This regimen has shown significant reductions in certain side effects, including cholesterol and triglyceride levels, without compromising treatment efficacy.
The discovery of the Jaragua Sphaero, a lizard measuring about three quarters of an inch from snout to tail, highlights the Caribbean's unique species diversity. Rapid population growth, agricultural practices, and lack of access to data contribute to the region's biodiversity loss.
A new study found that eliminating gatekeepers in health maintenance organizations (HMOs) does not necessarily increase costs. In contrast to traditional HMOs, point-of-service plans with open physician panels showed comparable spending on medical care expenditures, including physician services, hospital services, and prescription drugs.
A new study aims to determine the effectiveness of drug therapy, psychotherapy, or a combination in treating major depression in teenagers. The study, administered by Northwestern University Medical School, will enroll participants between 12-17 years old with clinician-diagnosed depression.
Scientists at Uppsala University have identified a gene that regulates mast cell survival upon allergic activation, providing hope for a novel therapy to treat allergies. Inhibition of this gene, A1, leads to the death of mast cells, decreasing their numbers and alleviating allergic symptoms.
Researchers found that groundwater in aquifers is generally older than expected based on flow velocity, due to mixing between aquitards and aquifers. This discovery has significant implications for estimating water supply yields and predicting contaminant migration rates.
Researchers have identified a molecule, GCNF, that restricts mouse cells' potency. This discovery may allow for the creation of embryonic stem cells without sacrificing embryos, opening up new avenues for research.
The newly discovered species, Sphaerodactylus ariasae, is the smallest of all 23,000 species of reptiles, birds, and mammals. The tiny lizard can curl up on a dime or stretch out on a quarter, measuring only 16mm long.
Researchers measured aerosols in clean marine conditions and under polluted conditions, revealing large concentrations of particulate material including mineral dust. The findings will help reduce uncertainties in global climate models and develop better policies.
A recent study by Washington University in St. Louis researchers attributes increased flood levels on the Missouri and Mississippi rivers to the placement of thousands of wing dams, built by the US Army Corps of Engineers in the 1930s and '40s. The structures impede water flow during floods, causing water levels to rise.
Research at Hope School found that animal-assisted therapy improved mobility, communication, compliance, and attention span in severely disabled children. The study suggested that a team effort among administrators, teachers, and staff is necessary for effective therapeutic interventions.
A randomized controlled trial found that unopposed estrogen therapy reduced atherosclerosis progression by .0017 millimeters per year in postmenopausal women. The study also showed that cholesterol-lowering drugs had a similar effect when combined with estrogen, suggesting potential benefits for cardiovascular health in women at risk.
Researchers have discovered a genetically distinct form of leukemia that affects infants in their first year, characterized by abnormal gene activity and stuck cell development. The 'Mixed Lineage Leukemia' may be treatable with designer drugs targeting its specific weak points.
Researchers found that people with back injuries use many unnecessary muscles to compensate for hurt areas, increasing twisting and compressive forces on the spine. A new rehabilitation strategy that emphasizes learning to use back muscles naturally could reduce the likelihood of repeat injuries.
The Johns Hopkins University Applied Physics Laboratory (APL) has been selected by NASA to develop the first mission to explore Pluto and the Kuiper Belt region. The New Horizons: Shedding Light on Frontier Worlds mission will use a team of scientists and engineers from various institutions to design, build, and operate the spacecraft.
A study found that dopamine transporter levels improved in methamphetamine abusers after prolonged abstinence, suggesting potential for recovery. However, cognitive and motor function did not show significant improvement, highlighting the need for further research.
Recent studies show that methamphetamine acts on the same brain mechanisms as cocaine and alcohol, disrupting dopamine receptors and glucose metabolism. Researchers found damage to brain cells may recover after prolonged abstinence from the drug.
Researchers found that delaying spinal cord injury treatment until the initial changes have stabilized can improve regrowth of injured neurons and axons. This combination therapy with fetal tissue transplants and nerve growth factors shows promise for treating severe spinal cord trauma.
Researchers led by Robert E. Braun analyzed gene expression after adenovirus delivery using both in vitro and in vivo studies. The study found no infection of reproductive stem cells, supporting the safety of adenovector use in cardiovascular therapy.
