A researcher believes that the potential human health implications of bee colony collapse disorder extend beyond the drop in pollination to the impact on humans of long exposure to low-level poisons, like neonicotinoid pesticides.
A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit.
Mice missing two important proteins of the vascular system develop normally and appear healthy in adulthood, as long as they don’t become injured. If they do, their wounds don’t heal properly, a new study shows.
Researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that could give doctors a simple blood test to reliably predict a person’s risk of attempting suicide.
Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200 percent jump in deadly melanoma cases since 1973.
When cancers spread into the bloodstream, they often take on different characteristics, requiring different therapies. But it is hard to find these rare blood-borne cells. So, relapsed patients often do not get personalized care. Now, researchers have come up with a solution that zeros in on elusive circulating tumor cells (CTCs).
Only 8.2 percent of human DNA is likely to be doing something important – is “functional”– say researchers. This figure is very different from one given in 2012, when some scientists stated that 80 percent of our genome has some biochemical function.
Vitamin D-deficient individuals are twice as likely to be diagnosed with schizophrenia as people who have sufficient levels of the vitamin, according to a new study.
Neuroscientists have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal.
If you consider your friends family, you may be on to something. A new study finds that friends who are not biologically related still resemble each other genetically.
Around half of the genes that influence how well a child can read also play a role in their mathematics ability, according to scientists who led a study into the genetic basis of cognitive traits.
Just as Nature was setting about retracting two famous Riken CDB papers claiming to make “STAP” stem cells from ordinary cells, another Riken researcher said she might suspend a world-first clinical trial of a competing—legitimate—stem cell technique. But within hours, she modified her views, according to Riken.
Scientists have discovered that obese individuals lack a protein that is essential for regulating blood glucose levels, causing them to face higher risks of developing diabetes.
By switching off a single gene, scientists have converted human gastrointestinal cells into insulin-producing cells, demonstrating in principle that a drug could retrain cells inside a person's GI tract to produce insulin.
Adults who watch TV for three hours or more each day may double their risk of premature death compared to those who watch less, according to new research.
Investors and gamblers take note: your betting decisions and strategy are determined, in part, by your genes. Researchers have shown that betting decisions are influenced by the specific variants of dopamine-regulating genes in a person's brain.
Researchers have determined that a copper compound known for decades may form the basis for a therapy for amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease.
Researchers have found that persons with lower blood levels of vitamin D were twice as likely to die prematurely as people with higher blood levels of vitamin D.
Young men who use cannabis may be putting their fertility at risk by inadvertently affecting the size and shape of their sperm, according to recently published research.
Nutritionists regularly suggest breakfast be eaten each morning for health benefits, including weight loss. But new research shows that, when comparing regularly consuming with regularly skipping breakfast, weight loss was not influenced.
The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory.
The risk of developing the most deadly form of skin cancer, melanoma, was more closely related to sun exposure in early life than in adulthood in young Caucasian women, according to a new study.
In an attempt to catalog the human “proteome,” a team of researchers identified 193 novel proteins that came from regions of the genome not predicted to code for proteins.
Could a common sexually transmitted infection boost a man’s risk for prostate cancer? A new study is exploring the connection between prostate cancer and the parasite that causes trichomoniasis, the most common non-viral sexually transmitted infection in men and women.
