Scientists have shown that if oxytocin is administered to men and if they are shown pictures of their partner, the bonding hormone increases the attractiveness of the partner and strengthens monogamy.
Healthy adults who consumed energy drinks high in caffeine and taurine had significantly increased heart contraction rates one hour later, according to a new study.
A new study suggests that a diet low in vitamin D causes damage to the brain. The new evidence shows that vitamin D serves important roles in organs and tissue, including the brain.
Investigators have accomplished an important step toward their goal of creating primitive synthetic cells. The “protocells” they are building consist of a nucleic acid strand encased within a membrane-bound compartment.
An experimental device is letting paralyzed people drive wheelchairs simply by flicking their tongue in the right direction. Key to this wireless system: Users get their tongue pierced with a magnetic stud that resembles jewelry and acts like a joystick.
Research has suggested that a particular gene in the brain’s reward system contributes to overeating and obesity in adults.
Currently, there are no reliable treatments for cryptosporidiosis, the disease caused by Cryptosporidium parvum, but that may be about to change with the identification of a target molecule by a group of researchers.
A recently discovered HIV strain leads to significantly faster development of AIDS than currently prevalent forms, according to new research.
It’s long been thought that in people and in mice the reshuffling of B-cells— called V(D)J recombination, after the B-cells’ antibody-coding V, D and J gene segments— occurs in two places: the bone marrow and the spleen. New research suggests that there may be one more place B-cells go to undergo recombination: the gut.
Epidemiologists have designed a better method to quantify a woman’s risk of developing breast cancer, according to researchers.
Using a special MRI technique designed for studies of sleeping infants, researchers have found that infants who carry a gene associated with an increased risk for Alzheimer’s disease tend to have differences in brain development compared to infants who do not carry the gene.
Women who are members of families with BRCA2 mutations but who test negative for the family-specific BRCA2 mutations are still at greater risk for developing breast cancer compared with women in the general population, according to a new study.
The 1984 National Organ Transplantation Act that set the payment ban didn't just refer to solid organs — it included bone marrow transplants, too. Now, the government now has proposed a regulation to keep the ban intact by rewriting some legal definitions to clarify that it covers marrow-producing stem cells.
New research reveals that the nerve cells of mice with broken broken clocks show signs of deterioration before the externally visible signs of aging are apparent, raising the possibility of novel approaches to staving off or delaying neurodegeneration– hallmarks of Parkinson’s and Alzheimer’s diseases.
Why most new neurons die while a few survive has been a mystery. But now, a new neuroscience study shows how specific brain cells communicate with each other during adult neurogenesis– the creation of new neurons.
E-cigarettes have been widely promoted as a way for people to quit smoking conventional cigarettes. Now, in the first study of its kind, researchers are reporting that youth using e-cigarettes were more likely to be trying to quit, but also were less likely to have stopped smoking and were smoking more, not less.
A government study offers a new theory on why the whooping cough vaccine doesn't seem to be working as well as expected. The research suggests that while the vaccine may keep people from getting sick, it doesn't prevent them from spreading whooping cough to others.
New findings show that eating a high-fat diet beginning at puberty speeds up the development of breast cancer and may actually increase the risk of cancer similar to a type often found in younger adult women.
Scientists have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson’s disease.
A team of scientists looking into the interplay of the immune system and cancer have found a link between a history of airborne allergies– in particular to plants, grass and trees– with risk of blood cancers in women.
Asparagine, found in foods such as meat, eggs, and dairy products, was until now considered non-essential because it is produced naturally by the body. Researchers have now found that the amino acid is essential for normal brain development.
The Food and Drug Administration has ordered Google-backed genetic test maker 23andMe to halt sales of its personalized DNA test kits, saying the company has failed to show that the technology is supported by science.
Cancers that occur in later life could be down to the way our cells age, according to a new paper that says some cancers could be caused by older cells bypassing the switch that tells them to stop growing.
One of the smallest parts of the brain is getting a second look after new research suggests it plays a crucial role in decision making.
A research team has identified an immune cell protein that is critical to setting off the body’s initial response against viral infection.
