Researchers have discovered how prostate cancer stem cells evolve as the disease progresses, a...
With few exceptions, cells don’t change type once they have become specialized. However, new...
Stress from having to keep a secret– one’s sexual orientation, for example, or simply a forbidden word– can cause lapses in physical stamina, intellectual acuity, executive function and even email etiquette.
In a new study, researchers report that increased activity in the medial prefrontal cortex of the brain is linked to decreased activity in the amygdala, the portion of the brain where memories of frightening events are created.
Genetic testing company 23andMe is facing a class action lawsuit alleging that the Silicon Valley startup misled customers about its test kit. The test is promoted as helping predict users' disease risk based on their DNA.
Researchers have identified a protein that causes loss of function in immune cells combatting HIV. The scientists report that the protein, Sprouty-2, is a promising target for future HIV drug development.
Researchers have identified a new genetic variant, located on chromosome 17, associated with sporadic amyotrophic lateral sclerosis (ALS)– the most common form of motor neuron disease.
A new brain connectivity study found striking differences in the neural wiring of men and women that’s lending credence to some commonly held beliefs about their behavior.
Chemical compounds found in cannabis, some of which also occur naturally in the body, may help to reduce brain damage following a stroke, new research has revealed.
For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells. The advance has significant potential for modeling lung disease, screening drugs, studying human lung development and generating lung tissue for transplantation.
Researchers have used radioimmunotherapy to destroy remaining HIV-infected cells in the blood samples of patients treated with antiretroviral therapy, offering the promise of a strategy for curing HIV infection.
President Barack Obama announced a new initiative at the National Institutes of Health in pursuit of a cure for HIV, saying his administration is redirecting $100 million into the project to find a new generation of therapies.
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.
Researchers have shown that they can grow unlimited quantities of intestinal stem cells, then stimulate them to develop into nearly pure populations of different types of mature intestinal cells.
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.
