Scientists developed simple, physics-based equations to address limitations of current cloud formation methods. A new instrument measures conditions needed for a particle to become a cloud droplet, helping determine how emissions affect cloud formation.
Research reveals that waiting increases consumption enjoyment for indulgent treats like chocolate, but decreases anticipation for non-pleasurable items. Consumers who wait longer tend to experience more satisfaction upon actual consumption.
A recent study published in Proceedings of the National Academy of Sciences reveals that the brain can be retrained to process sound in an alternative way, allowing for improved hearing sensitivity. This new system enables neurons to selectively fire at specific volume levels, making it more responsive to subtle changes in loudness.
A population-based study of nearly 2,300 US adults found a significant link between gastrointestinal disorders and insomnia. The study suggests that irritable bowel syndrome is more common among people with sleep disturbances than those without.
A new study by Fox Chase Cancer Center finds that a shortened course of radiation therapy for women after lumpectomy may be a viable alternative to traditional six-week treatments. The four-week treatment schedule showed comparable skin toxicity levels to longer courses, with most side effects resolving within six weeks.
A large phase III trial showed that sequential treatment with ELLENCE delivered superior disease-free and overall survival compared to FEC 100 alone. The sequential regimen resulted in a 17% reduction in relapse risk and a 23% reduction in mortality risk.
The phosphatidylinositol 3 kinase (PI3K) pathway is crucial in breast cancer development, with aberrant levels and mutations affecting critical growth factor receptors. Researchers believe targeting central nodes in this pathway can effectively treat the disease.
A recent study found that individuals exposed to high levels of lead are more likely to develop cataracts, with bone lead levels being the best predictor. The researchers estimate that lead exposure plays a role in approximately 42 percent of all cataracts in the studied population.
A study published in the Journal of Consumer Research found that past experience significantly impacts consumer decision-making, with thoughtful individuals relying on context to inform their choices. Non-thoughtful individuals, however, are aware of trade-off values but fail to utilize this information when making subsequent decisions.
Researchers found a three-fold increase in suicide rates in two Salisbury, N.C., neighborhoods downwind of an asphalt terminal. Hydrogen sulfide levels were significantly higher than the World Health Organization's recommended standard, and exposure to other neurotoxic compounds may also be contributing factors.
Researchers found that celecoxib reduced estrogen receptor expression by an average of 9% after six months of treatment. This finding confirms celecoxib's antiproliferative properties and suggests a new potential therapeutic approach for breast cancer prevention.
A recent re-analysis of large clinical trials found that chemotherapy significantly improves survival rates in patients with ER-negative tumors, reducing the risk of death by 56 percent. The study suggests that chemotherapy has a greater impact on ER-negative patients than previously thought.
A new molecular test uses a panel of genes to predict the risk of breast cancer recurrence and identify patients who will benefit from chemotherapy. The test shows that women with low risk of recurrence do not derive much benefit from chemotherapy, while those with high risk have a large benefit.
A new immunosuppression protocol has significantly reduced the need for anti-rejection medications in intestinal transplant patients, resulting in a 96% one-year survival rate. The study showed that 69% of patients are taking a single dose of immunosuppression, and none experienced chronic rejection.
A unique study examines how African-American consumers use shopping to express their political beliefs in a time when traditional forms of participation are decreasing. The research highlights the importance of considering consumer politics in understanding social and political relations.
Researchers recreated extreme conditions to find that rocks rich in chromium minerals accelerate the production of more complex hydrocarbons. This process may help explain the diverse communities thriving around hydrothermal vents.
A recent study by the University of Alberta found that melatonin supplements have little to no benefit for individuals suffering from sleep disorders or experiencing jet lag. While some people may fall asleep sooner with melatonin supplementation, its effects on overall sleep quality are minimal.
Researchers at Scripps Institution of Oceanography have cloned a gene from the marine invertebrate Bugula neritina, which may prove key in developing new cancer drugs. The cloned gene, bryA, is thought to be involved in the production of bryostatin, a family of chemical compounds with potential as anticancer pharmaceuticals.
