Here’s another reason why it’s a good idea to hit the gym: it can improve memory. A new study shows that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults.
Researchers have shown for the first time that a genetic switch allows Streptococcus...
What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip...
Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new research.
New research on an enzyme linked to cancer development shows that 37 percent of mice that produce excessive quantities of the enzyme developed skin tumors within four to 12 months of birth, and many of these growths progressed to highly invasive squamous cell carcinoma, a common form of skin cancer.
New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms.
People with blood type AB were 82 percent more likely to develop the thinking and memory problems than people with other blood types, according to a new study.
Some people avoid risks at all costs, while others will put their wealth, health, and safety at risk without a thought. Researchers have found that the volume of the parietal cortex in the brain could predict where people fall on the risk-taking spectrum.
Are humans programmed to tell the truth? Not when lying is advantageous, says a new study. The report ties honesty to a region of the brain that exerts control over automatic impulses.
A meta-analysis comprising 16 studies and 891,426 participants from various regions of the world shows that prediabetes increases the risk of cancer by 15 percent, with differing risks depending on the type of cancer.
Sleep difficulties may be linked to faster rates of decline in brain volume, according to a new study. Sleep has been proposed to be “the brain’s housekeeper,” serving to repair and restore the brain.
In response to an ongoing, unprecedented outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers has rapidly sequenced and analyzed more than 99 Ebola virus genomes.
A new study revealed the brain circuit that controls how memories become linked with positive or negative emotions, and researchers found that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics.
Men who eat over 10 portions a week of tomatoes have an 18 per cent lower risk of developing prostate cancer, new research suggests. This is the first study of its kind to develop a prostate cancer "dietary index."
Older adults losing vision as they age are more likely to face an increased mortality risk, according to new research. The researchers analyzed data from the Salisbury Eye Evaluation study that tracked the vision health of 2,520 older adults, ages 65 to 84.
As, all around them, everyone from Derek Jeter to the Kennedy family was dousing themselves in ice water for the ALS “Ice Bucket Challenge,” Harvard researchers announced last week they may have found an ALS therapy— or two.
Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain “pruning” process during development, according to a new study.
The birth control pill significantly affects ovarian reserve— or the number of immature eggs in a woman’s ovaries— which can be a predictor of future fertility, according to a team in Denmark.
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.
