A recent study found that individuals clinically identified as substance abusers have an elevated risk of injury. Alcohol-and-drug abusers had the highest risk of injury, followed by those who abused only one type of substance.
Researchers propose a blood test to diagnose schizophrenia by measuring the levels of mRNA molecules encoding D3 dopamine receptors on white blood cells. This test may help assess the biological basis of the disease, which is still unknown.
Researchers develop new therapies targeting related virus proteins, aiming to neutralize the effects of smallpox. The US population is highly susceptible due to low vaccination rates and limited vaccine stockpiles.
A study by NASA researchers found that the eastern U.S. has cooled by 0.1° Celsius per decade, contrasting with global warming. The researchers attribute this cooling to increased cloud cover caused by warmer ocean temperatures in the Pacific.
Research suggests that specific cognitive processes, individual characteristics, and environmental conditions influence alcohol's effects on behavioral control. Alcohol can impair cognitive control of response inhibition, but this effect varies among individuals.
Research reveals CPY26 degrades retinoic acid to establish uneven distribution, crucial for normal embryonic development. Elevated RA levels in Cpy26 mutant mice lead to severe developmental defects, highlighting the enzyme's protective role.
The Relativistic Heavy Ion Collider (RHIC) has created nuclear matter with the highest energy density ever achieved, opening a new frontier in scientific exploration. The experiment also reveals striking differences from previous experiments, hinting at new phenomena and a possible transition to quark-gluon plasma.
Researchers have identified the three-dimensional atomic structure of a critical gene-regulating molecule, revealing its importance in human diseases such as cancers, autoimmune disorders, and developmental disorders. The discovery could lead to the development of new treatments and therapies for these conditions.
As people age, they experience a decrease in muscle strength, but an increase in endurance. To address this issue, Maury Nussbaum and Laura Wojcik are conducting a study to understand how tasks can be adjusted to accommodate older workers' work capacity.
A Penn State researcher explains how atmospheric chemistry can alter the composition of air, affecting environmental quality, and how pollutants like acetone and formaldehyde contribute to ozone production. The study also explores the role of nitrogen oxide in complex chemical reactions that produce hydrogen oxides.
A laboratory study found that vitamin E concentrations did not interfere with the killing of cancer cells by radiation therapy. However, the study's limitations mean that the impact on real-world treatment outcomes is unclear.
Researchers found that aerobic exercise improved specific areas of cognitive function, including memory and executive functions, beyond what was expected after depression lifted. The study suggests that exercise may offset some mental declines associated with aging.
A California-based study found significant ethnic differences in DUI arrest rates and healthcare service utilization among Hispanic populations, particularly Mexican Americans. Despite higher rates of heavy drinking, this group tends to underutilize health services, with lower utilization among those born in Mexico.
