The risk for head injury was also found to be higher among snowboarders than alpine skiers, highlighting the importance of helmet use in preventing these injuries.
A male-specific gene, SRY, has been found to be linked to the control of physical movement and may contribute to the higher incidence of Parkinson's disease in men. The protein, which determines male gender, was discovered in British scientists in 1990.
A protein called MEF2 has been found to regulate the growth and development of synapses in neurons. The study reveals that MEF2 can promote or inhibit synapse formation depending on neuronal activity, with implications for understanding neurodegenerative diseases such as autism.
A Phase 1 trial of an Ebola DNA vaccine demonstrated strong immune responses in all fully vaccinated volunteers. The vaccine, developed by Vical, was well-tolerated and showed effectiveness against Ebola-specific antibodies.
A national survey found that 78% of hospitals do not require general pediatricians to be board certified at the time of initial privileging, but 70% require it at some point during their tenure. Many hospitals have no specific time limit for certification,
The new rotavirus vaccine RotaTeq has been added to the routine infant immunization schedule in the US, following its approval by the FDA. The vaccine is expected to prevent severe cases of rotavirus gastroenteritis and reduce hospitalizations.
The NIH Cognitive and Emotional Health Project aims to coordinate research on interventions for neurological health. The report highlights the interconnectedness between cognitive and emotional health, emphasizing the need to examine them simultaneously.
Researchers have successfully demonstrated that quantum dots can transfer energy in a "coherent" fashion when exposed to light, paving the way for potential optical quantum computing and medical imaging applications. This breakthrough could lead to faster and more efficient computers, as well as reduced heat generation.
A new study by the University of Illinois at Urbana-Champaign found that girls outperform boys in math grades due to their learning-oriented approach. However, when it comes to math achievement tests, the gap disappears, suggesting that confidence plays a crucial role.
New research reveals deep-sea pelagic fish are congregating at the Mid-Atlantic Ridge for spawning, challenging long-held nomadic wanderer myth. MAR-ECO project discovers six new species and unusually large specimens, shedding light on deep-sea ecosystems.
The European Union has faced a staggering €169 billion economic burden due to cardiovascular disease (CVD), accounting for 12% of all healthcare expenditures. CVD resulted in 2 million deaths and 4.4 million people being severely hampered by daily activities, highlighting the need for policy makers to prioritize research spending.
Researchers used virtual-reality displays to show that humans can't accurately judge size and distance when motion is present. Instead, they prefer a stable representation of the world independent of head and eye movements.
Scientists at Woods Hole Oceanographic Institution use ocean gliders to collect passive acoustic recordings of baleen whales, including right, sei, and humpback whales. The gliders' findings suggest a close correspondence between changes in sei whale calls and near-surface copepod abundance.
Researchers from the UAB have found a direct relationship between morphine addiction and a tendency to explore perseveringly in rats. The study suggests that individuals with a greater propensity to seek new sensations may be more likely to develop an addiction to morphine.
A new study found that breeding Zambian mole-rats lived up to 20 years and twice as long as non-breeding individuals. The researchers suggest this could be due to the species' eusocial lifestyle and pair-bonding habits, making it a valuable model organism for studying aging mechanisms.
A team of University of Wisconsin-Madison scientists reports that the brain can be rewired in anticipation of sensory input to respond in prescribed ways. By manipulating expectancy, the brain code for tastes is activated less when a cue suggests a lesser taste, and the perception of the taste matches the prediction.
Researchers found high levels of selenium in contaminated toads and their offspring, leading to developmental abnormalities such as structural malformations and abnormal swimming. The study highlights the importance of maternal transfer in contaminant exposure for amphibians.
A recent study by Turi King and colleagues found that men who share surnames are more likely to have similar Y chromosomes, suggesting a common ancestor within the past 20 generations. The research has implications for genealogy and forensic science, as it may enable surname prediction from DNA alone.
Researchers found that well-dressed and groomed women received friendlier service, while appearance had a limited impact on greeting times. The study suggests that assumptions about customers' spending power drive salesclerks' behavior.
Researchers found that the public underestimates certain bacteriological hazards while overestimating those with low prevalence, like mad cow disease. Experts believe early school intervention and media training can improve public understanding of food risk messages.
A study found that high-status male macaques took longer to follow the gaze of other dominant monkeys compared to low-status individuals. The researchers suggest that testosterone levels in high-status males may suppress social vigilance, a trait often seen in low-status males.
