Scientists have discovered an algae virus never before seen in the throats of healthy people that may subtly alter a range of cognitive functions including visual processing and spatial orientation in those who harbor it.
A research team has sequenced the genome of a 45,000-year-old modern human male from western...
Scientists have described a way to convert human skin cells directly into a specific type...
Researchers have successfully transplanted “organoids” of functioning human intestinal tissue grown from pluripotent stem cells in a lab dish into mice– creating an unprecedented model for studying diseases of the intestine.
As San Diego’s ViaCyte was in the midst of launching the first FDA-approved embryonic stem (ES) cell clinical trial for diabetics last week, Boston’s Harvard University reported that cells made from ES cells “cured” diabetic mice.
Results of a small clinical trial suggest that a chemical derived from broccoli sprouts— and best known for claims that it can help prevent certain cancers— may ease classic behavioral symptoms in those with autism spectrum disorders (ASDs).
Scientists have discovered a new class of molecules– produced in human and mouse fat– that protects against diabetes. The researchers found that giving this new fat to mice with the equivalent of type 2 diabetes lowered their elevated blood sugar.
Studying rats as model subjects, scientists found that adolescents were at an increased risk of suffering negative health effects from sugar-sweetened beverage consumption.
How much coffee do you drink every day? One cup in the morning? Or do you gulp it all day? Scientists have long known that your DNA influences how much java you consume. Now a huge study has identified some genes that may play a role.
The largest genome-wide association study (GWAS) to date, involving more than 300 institutions and more than 250,000 subjects, roughly doubles the number of known gene regions influencing height to more than 400.
A new study found that a bias toward certain types of DNA sequences during gene conversion may be an important factor in why certain heritable diseases persist in populations around the world.
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 pneumoniae to randomly change its characteristics into six alternative states.
What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip of Africa tell us about ourselves as humans? A great deal when his DNA profile is one of the "earliest diverged"– oldest in genetic terms– found to-date in a region where modern humans are believed to have originated roughly 200,000 years ago.
The first animal model for ALS dementia, a form of ALS that also damages the brain, has been developed by scientists. The advance will allow researchers to directly see the brains of living mice, under anesthesia, at the microscopic level.
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.
