Scientists have determined the most detailed picture yet of a crucial part of the hepatitis C virus, which the virus uses to infect liver cells. The new data reveal unexpected structural features of this protein and should greatly speed efforts to make an effective hepatitis C vaccine.
Researchers have shown that tiny quantities of the protein tau can be enough to kick-start an aggregation process which may explain the onset of Alzheimer’s in the brain.
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.
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.
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.
Scientists have charted a significant signaling network in a tiny organism that's big in the world of biofuels research.
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
A novel immune-boosting drug combination eradicates glioblastoma brain cancer in mice, according to a new study.
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.
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.
Chemical engineers have developed a novel way to generate nanoparticles that can recognize specific molecules, opening up a new approach to building durable sensors for many different compounds.
A research team has identified an immune cell protein that is critical to setting off the body’s initial response against viral infection.
