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.
As humans, how, and why, do we think and act so differently from other species? A new study suggests that the big difference between humans and other species may lie in how we use our brains for routine tasks.
A research team has just discovered that melatonin supplements make bones stronger in elderly rats and therefore, potentially, in elderly humans, too.
Scientists have discovered a pair of genes that normally keeps eating schedules in sync with daily sleep rhythms, and, when mutated, may play a role in so-called night eating syndrome.
Blocking a pain receptor in mice not only extends their lifespan, it also gives them a more youthful metabolism, including an improved insulin response that allows them to deal better with high blood sugar.
A group of 11 genes can successfully predict whether an individual is at increased risk of alcoholism, a research team recently reported. Knowing one has a genetic predisposition to alcohol abuse could encourage behavioral and lifestyle changes.
High cholesterol levels may impair fertility in couples trying to achieve a pregnancy, according to a new study. Couples in which each partner had a high cholesterol level took the longest time to reach pregnancy, the study showed.
A new study uses genetic information extracted from the remains of an adolescent girl to help resolve the longstanding debate about the origins of the first people to inhabit the Americas.
The caffeine in coffee that might help get you going in the morning can be lifesaving for premature babies. For more than a decade, neonatologists have routinely given premature newborns caffeine as a respiratory stimulant, helping their immature lungs and brains remember to breathe.
A group of researchers say they have identified a genetic marker that may be associated with the development OCD, the causes and mechanisms of which are some of the least understood among mental illnesses.
Health officials have confirmed a second U.S. case of a mysterious virus that has sickened hundreds in the Middle East. A news conference to discuss the case has been scheduled for Monday afternoon by the Florida Department of Health and the CDC.
A newly identified difference between the brains of women and men with multiple sclerosis (MS) may help explain why so many more women than men get the disease, researchers report.
Eating more fruits and vegetables may reduce the risk of stroke worldwide, according to new research. The beneficial effects applied consistently to men and women, stroke outcome and by type of stroke.
In a world-first, researchers have discovered one of the main reasons behind why cancer spreads throughout the body: the help of "bad" cholesterol. The research found that LDL regulates the machinery that controls cell migration.
Health officials confirmed the first case of an American infected with a mysterious virus that has sickened hundreds in the Middle East. Federal and state health officials announced on Monday that they are scheduled to discuss their response to the illness.
Stem cell therapy can regenerate heart muscle in primates, according to a new study. The scientists on this and related projects are seeking way to repair hearts weakened by myocardial infarctions.
Large sections of the genome that were once referred to as “junk” DNA have been linked to human heart failure, according to new research. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn’t code for proteins.
520 million years ago, the first known animal heart, the heart of an ancient shrimp, was formed. Now, it, and its vascular system, have been found to be more complex than that of modern shrimp, researchers report.
A newly identified genetic disorder associated with degeneration of the central and peripheral nervous systems in humans, along with the genetic cause, has been reported.
The process of metastasis is still poorly understood. Now, a research team has developed a simple test that can reveal the evolutionary relationships among various tumor sites within a patient, information that may someday help with treatment planning.
Scientists have worked together to create tools for observing nerves in living animals that signal between themselves in real time, which will help them understand how those individual signals add up to the complex collection of a person's thoughts and memories.
Researchers say that rapid-eye-movement sleep behavior disorder (RBD), which causes people to act out their dreams, is the best current predictor of brain diseases like Parkinson's and Alzheimer's.
Although doctors have long known that people with Down syndrome have a heightened risk of developing acute lymphoblastic leukemia (ALL) during childhood, they haven’t been able to explain why. Now, a team investigators has uncovered a connection between the two conditions.
Researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: when a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them.
