Every day in hospitals around the world, patients suffer painful allergic reactions to the medicines they are given. The reactions, known as pseudo-allergies, often cause patients to endure itchiness, swelling and rashes as an unwanted part of their treatment plan. The reactions can be so severe they may stop patients from taking their needed medications and sometimes can even prove fatal.
Researchers have determined that two mutations on a single gene can interact in a way that lowers the carrier's risk for a heart attack. The variants are found in a gene called DBH, which regulates an enzyme involved in the conversion of dopamine to norepinephrine - both of which are important chemical messengers and hormones.
The thousands of mitochondrial DNA (mtDNA) molecules present in each cell are known primarily for their role converting food and oxygen into energy. But Yale researchers have identified an unexpected relationship between mtDNA and the innate immune response.
A new study by Tel Aviv University's Prof. Illana Gozes, published in Translational Psychiatry, may offer insight into the pathology of both autism and Alzheimer's by revealing that different activities of certain proteins in males and females cause gender-specific tendencies toward these diseases.
Britain's House of Commons gave preliminary approval to permitting scientists to create babies from the DNA of three people, a technique that could protect some children from inheriting potentially fatal diseases from their mothers. Read more...
The discovery of a new reset button for the brain’s master biological clock could eventually lead to new treatments for conditions like seasonal affective disorder, reduce the adverse health effects of working the night shift and possibly even treat jet lag.
New research could lead to a better understanding of how the brain works in people with autism.
Recognizing the faces of family and friends seems vital to social interaction.
Many packaged meals and snacks for toddlers contain worrisome amounts of salt and sugar, potentially creating an early taste for foods that may contribute to obesity and other health risks.
President Obama held a press conference revealing new details surrounding the Precision Medicine initiative he announced during the State of The Union.
This is the first official look at the life sciences division of Google X.
Researchers have begun to appreciate the importance of copy number variation when considering the connections between DNA and disease.
Women in their late thirties and forties who have trouble sleeping are more than three times more likely to suffer sleep problems during menopause than women who have an easier time getting shut-eye.
This research could move the medical community one step closer toward effectively detecting concussion and quantifying its severity.
A measles outbreak in Arizona that originated at California's Disney parks is at risk of increasing dramatically in size as health officials keep tabs on 1,000 people, including nearly 200 children who could have been exposed at a Phoenix-area medical center.
The U.N. health agency said the three most affected countries - Guinea, Sierra Leone and Liberia - have reported fewer than 100 cases in the past week, for the first time since June.
For the first time, scientists have revealed a mechanism underlying the cellular degeneration of upper motor neurons, a small group of neurons in the brain recently shown to play a major role in ALS pathology.
The skull dates from around 55,000 years ago, fitting into the period when scientists had thought the migrants inhabited the area.
Evidence is rapidly growing showing vital relationships between both diet quality and potential nutritional deficiencies and mental health, a new international collaboration led by the University of Melbourne and Deakin University has revealed.
Cornell researchers have achieved this feat in rats by engineering human lactobacilli, a common gut bacteria, to secrete a protein called Glucagen-like peptide 1 (GLP-1).
Populations of certain types of marine organisms known collectively as the ‘biofouling community’ – tiny creatures that attach themselves to ships’ hulls and rocks – may quadruple within decades, while others may see their numbers reduced by as much as 80 percent, if the world’s oceans continue to become more acidic, according to new research.
The Food and Drug Administration (FDA) has approved for evaluating in people a nanoparticle-based imaging agent jointly developed at Washington University School of Medicine in St. Louis and the University of California, Santa Barbara, in collaboration with Texas A&M University.
Cells are incredibly complicated machines with thousands of interacting parts — and disruptions to any of those interactions can cause disease.
Killer T cells are one of the body's main lines of defense against pathogens.
