A recent study found that a combination of growth hormone and sex steroids showed significant increases in lean body mass and decreases in fat mass, but also reported common side effects such as joint pain and swelling. The study suggests that the treatment is not yet ready for prime time due to its adverse effects.
Researchers from the University of California - Irvine discovered that even a single intense bout of exercise in teens and preteens raises cellular chemicals associated with disease while building muscle mass and increasing fitness. The study suggests a need to determine how much exercise is too much for healthy children.
Researchers at Alberta Research Council have developed a working demonstration unit of micro fuel cell technology, capable of powering a small electric fan. The single-cell fuel cell uses hydrogen gas as a fuel and can be adapted to run on various fuels, including natural gas and butane.
A study of 610 participants found that wearing an ionized bracelet for 28 days did not provide significant pain relief compared to a placebo. The researchers conclude that the equivalent improvement in pain scores may call into question the true benefit of using such bracelets.
Mayo Clinic researchers identified Mycobacterium avium complex as the cause of 'hot tub lung', a previously poorly understood disease. The study found that warm temperatures and inadequate cleaning practices facilitate the growth of MAC in hot tub water, leading to respiratory problems.
Researchers found a significant correlation between maternal placenta inflammation and infant neurological function decline. The study revealed chorioamnionitis as a key cause of perinatal brain injury, potentially leading to new diagnostic tests and preventive strategies.
Research suggests that reducing air pollution can lead to significant cost savings in healthcare, particularly for outpatient care. The study found a strong correlation between air pollution levels and respiratory admissions, with the greatest hospital admissions occurring in the Deep South.
A recent study of 289 identical twin pairs reveals that twins differ in their feelings of emotional distress, despite being genetically identical. The twin who was less distressed tended to have closer relationships with their mother and teachers, attend church more often, or had parents granting them more autonomy.
A study found that an uncommon variation of the Nogo gene increases schizophrenia risk, particularly when inherited from both parents. One in five people with schizophrenia has this risk gene, and researchers hope to discover new related genes to aid diagnosis and treatment.
Researchers found a link between maternal testosterone levels and increased masculine-typical behavior in girls, but no correlation for boys. The study analyzed data from over 13,000 children born in England and suggests that hormone-related predispositions may play a role in shaping gender roles.
A study published in the Journal of the American Medical Association found that training improved certain thinking and reasoning abilities in older adults. The training focused on developing strategies to improve memory, problem-solving, and concentration, but did not affect daily living skills.
The NSF has awarded a design grant for the Square Kilometer Array (SKA) telescope, which aims to be the largest scientific instrument ever built. The U.S. consortium, led by Cornell University, will investigate feed antennas and low-temperature receivers, as well as address radio frequency interference issues.
A recent study found significant differences in healthcare quality for elderly individuals across various ethnic groups. Black patients showed greater disparities compared to white patients, while Hispanic women had even more pronounced gaps in breast cancer screening rates than black women. The study highlights the need to address the...
A recent study found that family income influences children's outcomes through different pathways, including providing a stimulating learning environment and addressing economic instability. The researchers suggest offering packages of services to families to promote healthy development in young children.
Family income significantly impacts preschool children's cognitive development and behavior, with higher-income families providing more stimulating learning environments and lower-income families facing economic pressure that leads to behavioral problems. The study suggests offering programs promoting learning materials, family literac...
Researchers have gained a new understanding of how quinoline-based drugs work against the Malaria parasite, slowing crystal growth to toxic levels and killing the parasite. The study provides insights into physical chemistry and crystalline surface structure to explain drug action, offering potential solutions to drug resistance.
Researchers used fMRI to compare representation of repetition rate across cortical and subcortical structures in human auditory pathway. Findings revealed distinct patterns of activity in response to trains with varying repetition rates, shedding new light on neural representations of sound perception.
The NIH has awarded a $4.6 million grant to Rutgers University to develop new and effective drugs for AIDS. The five-year program will use structure-based drug design to identify proteins involved in HIV transmission and develop inhibitors that can overcome drug resistance.
A clinical trial using lab-grown T cell clones has shown promise in shrinking melanoma tumors. In the study, five patients saw their tumors stop growing for up to a year, while three experienced tumor shrinkage.
Researchers probing strong nuclear force's nature encounter surprise at RHIC in Brookhaven, NY., where particles stream out faster from football-shaped collision tips than sides. This defies treasured boost invariance theory and complicates understanding of collisions.
Researchers from the University of Houston are using a $3.2 million grant to develop computer models tracking dioxin movement through the environment. The study will provide critical data for regulatory agencies to implement plans reducing pollutants and achieving minimum water quality standards.
A Rutgers-led consortium has received $6.5 million in funding from the NIH to determine the three-dimensional structure of hundreds of new proteins. The project aims to make protein structure determination less expensive and develop new techniques.
The Crop Science Society of America partners with Pioneer Hi-Bred International to create the Pioneer Fellowship in Plant Sciences, providing $25,000 annual stipends for four years. The fellowship aims to advance plant improvement through education and research.
A recent study by HealthPartners found that insurance coverage for smoking cessation programs had no significant effect on quitting rates. Despite previous studies suggesting the effectiveness of bupropion and nicotine replacement therapy, researchers found that smokers with coverage were no more likely to quit than those without it.
Preservatives can be grouped into three types: antimicrobials, antioxidants, and enzymes that fight natural ripening. Sulfur dioxide blocks microbial growth in foods, while propionates and benzoates help keep bakery products fresh.
A recent study by Texas A&M University researchers suggests that natural climate variability may contribute up to half of the observed global surface warming since the 1970s. The analysis of ocean surface temperature records in the tropical Pacific indicates that long-term changes in ocean temperatures precede global air temperature ch...
Researchers used GIS techniques to assess New Minia City's site risk and bedrock stability, revealing soft limestone prone to dissolution. The model was found effective in identifying geo-environmental problems, allowing for informed decision-making on sustainable development.
A new study from the University of Washington found that neither natural porcine secretin nor a synthetic form of the hormone reduced symptoms of autism. The research involved 85 children with autism and tested the effects of both forms of secretin versus a placebo, concluding there is no evidence for its effectiveness.
A University of Michigan study found that people who provided practical support to others were more than twice as likely to survive as those who did not. The researchers analyzed data from over 423 older couples and found a significant link between giving and longevity.
