The study found an association between a specific GABA receptor gene and alcohol dependence, suggesting a potential genetic link. The findings support the idea that brain overactivation may contribute to predisposition to alcoholism.
Researchers found that regular ecstasy users experienced mainly long-term memory difficulties and were 23% more likely to report problems than non-users. Those who also used cannabis reported up to 20% more memory problems due to the 'double whammy' effect.
A team of scientists has successfully used a 'robot scientist' to discover the function of about 30% of genes in baker's yeast (Saccharomyces cerevisiae), which could lead to major medical breakthroughs. The robot, trained on biochemistry knowledge, designed experiments and analyzed data using plate readers.
The study found that selling untreated used oil as fuel causes high levels of heavy metal emissions, including zinc and lead. Recycling and re-refining programs are recommended to reduce this environmental burden and promote safer alternatives.
A study found that adolescent rodents experience less anxiety and recover faster from a hangover than adult rodents. In contrast, adolescents tend to drink more in social situations due to the lack of aversive effects, which may lead to dependency.
According to a new study, 32% of autistic children use complementary and alternative medicine, with Latino children more likely to do so. The researchers caution that some CAM treatments may alleviate associated problems but not core autism symptoms.
A new study reveals that a significant part of the aquatic food chain is supported by terrestrial organic matter originating on the shoreline. Aquatic plants produce organic carbon through photosynthesis, which supports fish and invertebrate populations.
The SeaWinds scatterometer on NASA's QuikSCAT satellite provides ocean surface wind speed and direction measurements, leading to improved storm predictions at sea. This increased accuracy brings economic savings and reduces weather-related loss of life, especially in global shipping.
Researchers discovered that rats bred to prefer alcohol were healthier and lived longer than those bred to avoid it, regardless of drinking habits. The study found that genetic factors, rather than alcohol consumption itself, contributed to the longevity difference.
A study found that genetic variation can influence motivation to drink alcohol, particularly to alleviate social anxiety and improve mood. This can lead to enhanced behaviors that increase the risk for alcoholism. The study suggests a link between genetic factors and drinking motives, providing insight into the biology of alcoholism.
A team of LSU researchers is contributing to the largest-ever cosmic-ray experiment, analyzing data from a $100 million facility in Argentina. The project aims to understand the origin and properties of high-energy cosmic rays, which have puzzled scientists for years.
A study of 51 heavy smokers found that over 90% believed quitting was more threatening than the dangers of smoking. Many smokers feel angry and see themselves as victims who have been duped into smoking. The study also revealed that social pressures, stress relief, and fear of withdrawal symptoms hindered their ability to quit.
Corn earworm moths travel at varying heights influenced by air currents, affecting their migration patterns. By analyzing wind patterns and weather forecasts, researchers aim to forecast the arrival of these pests and develop targeted insecticide strategies to reduce damage.
A study by Pace and colleagues found that 40-55% of lake plant production supports resident aquatic life, while 2250% of zooplankton is derived from terrestrial sources. The results suggest that aquatic food chains are supported not only by in-water production but also by organic matter from surrounding watersheds.
A telephone counseling program was found to be more effective in helping smokers quit than a less-intensive mailing plan. The study showed that participants who received the phone counseling had a reduced chance of smoking after one year, with a significant association between the type of counseling and smoking behavior.
A UMHS study found that heavy drinkers with chronic back pain showed less physical disability than light drinkers on functional tests. Women were underreported for heavy drinking, suggesting doctors should be more vigilant about prescribing narcotic pain relievers.
Researchers at Florida Institute of Technology are developing new models to understand hacker tactics, with the goal of creating defensive techniques against cyber attacks. The project aims to break the cycle of cat and mouse games between hackers and defenders.
Researchers have identified a consistent association between alcohol dependence and the GABRG3 gene, which may suggest a genetic predisposition to increased risk of developing alcoholism. The study found that this gene plays a role in influencing the risk for alcoholism by altering brain state and circuit activity.
Researchers discover transgenic mosquitoes are severely impaired in development and reproduction, laying fewer eggs and having lower egg-adult survivorship. This finding has major implications for the competitiveness of transgenic mosquitoes against non-engineered wild-types.
Researchers at Penn State have created a new form of supersolid matter by freezing helium-4, exhibiting properties of both solids and fluids. The discovery, funded by the National Science Foundation, suggests that under certain conditions, some fraction of the helium atoms can move through the lattice like a superfluid.
A report by Dr. Simpson and Denise Dougherty highlights the need for pediatricians and parents to collaborate on improving children's health care, focusing on quality indicators and evidence-based practice. The authors recommend creating an information technology system to track health care indicators and provide better care for children.
Researchers Chan and Kim create a supersolid by compressing helium-4 gas into a glass disk with miniature pores at extremely low temperatures. The experiment suggests that all three states of matter can enter the 'super' state, known as Bose-Einstein condensation.
This year's flu season is severe due to a mutated virus that has changed slightly since last year's vaccine was designed. Young children are at higher risk of getting seriously ill as they haven't encountered the virus before and lack immunity. Experts recommend vaccinating all children aged 6 months to 23 months to prevent complications.
