Avoiding or controlling diabetes may reduce cancer risk and mortality (April 4, 2011) -- Diabetes is associated with lower risk of prostate cancer in men but with higher risk of other cancers in both men and women, according to new research. The data also showed an association between diabetes and higher cancer mortality rates. ... > full story
The five hospital factors that affect heart attack survival (April 4, 2011) -- A new study looks at why there is such a big difference in the mortality rates among patients treated for heart attacks in hospitals across the United States. ... > full story
New research demonstrates language learners' creativity (April 4, 2011) -- New research shows that language learning goes well beyond simple imitation, and in fact that language learners are quite creative and remarkably smart. Not only are learners able to generalize grammatical restrictions to new words in a category -- in this case, made-up adjectives -- but they also do not learn these restrictions in situations where they can be attributed to some irrelevant factor. ... > full story
Metabolic syndrome may increase risk for liver cancer (April 4, 2011) -- Scientists have confirmed that metabolic syndrome, a constellation of conditions that increases the risk of heart disease and diabetes, may also increase the risk of the two most common types of liver cancer. ... > full story
ADHD and prenatal alcohol exposure: Comparing profiles of learning and memory impairments in two groups of children (April 4, 2011) -- A new study has compared the verbal learning and memory performance of children with heavy prenatal alcohol exposure (PAE) with that of children with attention-deficit/ hyperactivity disorder (ADHD). The children with PAE had initial problems with learning information, reflecting inefficient encoding of verbal material. The children with ADHD had difficulty retaining information over time, reflecting a deficit in retrieval of learned material. ... > full story
Chasing the pot of gold: Gambling subtypes and treatment outcomes (April 4, 2011) -- Approximately two million adults in the United States meet criteria for pathological gambling, and another four to six million are considered problem gamblers, according to the National Council on Problem Gambling. A new study reveals that gambling addiction treatment is not one-size-fits-all, but it is difficult to predict which style of treatment is best for the various forms of gambling addiction. ... > full story
Vitamin D levels linked with health of blood vessels (April 3, 2011) -- A lack of vitamin D, even in generally healthy people, is linked with stiffer arteries and an inability of blood vessels to relax, researchers have found. ... > full story
‘SKIP’-ing splicing forces tumor cells to undergo programmed cell death (April 3, 2011) -- When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death. In contrast to other stress-induced genes, which dispense with the regular transcriptional entourage, p21Cip1 still requires SKIP, a transcription elongation factor that also helps with the editing of transcripts, to be expressed, found researchers. ... > full story
More organs for transplant when ICU docs help take care of brain dead donors, study finds (April 3, 2011) -- More than twice as many lungs and nearly 50 percent more kidneys could be recovered for transplant operations if intensive care physicians were to work with organ procurement organization coordinators to monitor and manage donor bodies after brain death has occurred, according to a new analysis. ... > full story
Heart drug cuts prostate cancer risk, holds potential for therapeutic use (April 3, 2011) -- New research suggests that men using the cardiac drug, digoxin, have a 24 percent lower risk for prostate cancer. The scientists say further research about the discovery may lead to use of the drug, or new ones that work the same way, to treat the cancer. ... > full story

Scientists unlock mystery of how the 22nd amino acid is produced (April 1, 2011) -- The most recently discovered amino acid, pyrrolysine, is produced by a series of just three chemical reactions with a single precursor -- the amino acid lysine, according to new research. Scientists have used mass spectrometry and a series of experiments to discover how cells make the amino acid, a process that until now had been unknown. ... > full story
Got a craving for fast food? Skip the coffee, study suggests (April 1, 2011) -- A new study has revealed not only that a healthy person's blood sugar levels spike after eating a high-fat meal, but that the spike doubles after having both a fatty meal and caffeinated coffee -- jumping to levels similar to those of people at risk for diabetes. Ultimately, saturated fat and fat combined with caffeinated coffee hinder the body's ability to clear sugar from the blood and having high blood sugar levels can take a toll on our body's organs. ... > full story
Promising target for AIDS vaccine (April 1, 2011) -- A section of the AIDS virus's protein envelope once considered an improbable target for a vaccine now appears to be one of the most promising, new research indicates. The section, a twisting strand of protein known as the V3 loop, is an attractive vaccine target because immune system antibodies aimed at the loop may offer protection against multiple genetic subtypes of HIV-1. ... > full story
Alzheimer's-like brain changes found in cognitively normal elders with amyloid plaques (April 1, 2011) -- Researchers using two brain-imaging technologies have found that apparently normal older individuals with brain deposits of amyloid beta -- the primary constituent of the plaques found in the brains of Alzheimer's disease patients -- also had changes in brain structure similar to those seen in Alzheimer's patients. Results of the study may someday lead to identification of candidates for preventive therapies. ... > full story
Brain scans reveal differences in brain structure in teenagers with severe antisocial behavior (April 1, 2011) -- Brain scans of aggressive and antisocial teenage boys with conduct disorder (CD) have revealed differences in the structure of the developing brain that could link to their behavior problems. The study reveals that the brain differences were present regardless of the age of onset of the disorder, challenging the view that adolescence-onset CD is merely a consequence of imitating badly behaved peers. ... > full story
Immune therapy can control fertility in mammals: Technique could prevent pregnancy in pets, human use is also envisioned (April 1, 2011) -- Researchers have shown that it is possible to immunize mammals to control fertility. They say their technique could possibly be used on other mammals -- including humans -- because fertility hormones and their receptors are species-non-specific and are similar in both females and males. For pets, the technique could be an alternative to castration and adverse effects of hormone administration. ... > full story
Regular breakfast helps reduce lead poisoning in children (April 1, 2011) -- It is known that fasting increases lead absorption in adults and consequently regular meals and snacks are recommended for children to prevent lead poisoning. New research demonstrates that having a regular breakfast is associated with lower blood lead levels in children. ... > full story
