Researchers have found that the genetic mutation BRAFV600E , frequently found in metastatic melanoma, not only secretes a protein that promotes the growth of melanoma tumor cells, but can also modify the network of normal cells around the tumor to support the disease's progression.
One of the most rapidly fast-tracked vaccines in history— an anti-Ebola “ChAd3” vaccine— just started clinical trial in humans, and may be done as soon as November. But a second fast-tracked anti-Ebola vaccine— called an “rVSV” vaccine— is hot on its heels.
Mice treated with antibiotics to remove most of their intestinal bacteria or raised under sterile conditions have impaired antibody responses to seasonal influenza vaccination, researchers have found.
A new study has identified a pathological process that takes place in both mice and humans towards one of the most common diseases that people face in the industrialized world: type 2 diabetes.
Using human induced pluripotent stem cells (hiPSCs), researchers have discovered that neurons from patients with schizophrenia secrete higher amounts of three neurotransmitters broadly implicated in a range of psychiatric disorders.
A research team is looking at whether an antibiotic has the potential to prevent or treat irregular heartbeats brought on by other medicines, thanks to a grant from national charity in the UK.
For the first time, scientists have turned human skin cells into transplantable white blood cells, soldiers of the immune system that fight infections and invaders.
Employing a measure rarely used in sleep apnea studies, researchers uncovered evidence of what may be damaging the brain in people with the sleep disorder— weaker brain blood flow.
The race to stamp out West Africa’s Ebola epidemic is not just about saving lives. It’s also about stemming an assault on society that could include food shortages and mass migration, morphing from a medical emergency into a broad humanitarian crisis.
A pharmacist who worked for a Massachusetts company blamed for a 2012 deadly nationwide meningitis outbreak has pleaded not guilty. Glenn Adam Chin entered his plea to a mail fraud charge at a brief hearing Thursday in federal court in Boston.
Researchers are working to create an online platform that health workers around the world can use to predict where malaria is likely to be transmitted using data on Google Earth Engine. Read more...
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.
On this episode of Bioscience Technology This Week, Christina Jakubowski discusses a new study that shows a link between idiopathic pulmonary fibrosis cases and asbestos exposure. Our second story showcases how immune cells use two critical receptors to clear dead cells from the body.
People who are obese may be more susceptible to environmental food cues than their lean counterparts due to differences in brain chemistry that make eating more habitual and less rewarding, according to a new study.
Taking benzodiazepines (widely prescribed drugs to treat anxiety and insomnia) is associated with an increased risk of developing Alzheimer's disease, particularly for long-term users, suggests a new study.
Scientists have discovered a novel cause of glaucoma in an animal model, and related to their findings, are now developing an eye drop aimed at curing the disease. They believe their findings will be important to human glaucoma.
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.
For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an “electronic skin” that “feels” and images small lumps that fingers can miss.
Scientists have developed a mathematical and computational technology that allows researchers to more accurately map the large, long connections within the white matter tissue of living human brains.
Over the years researchers have made tremendous strides in the understanding and treatment of cancer by searching genomes for links between genetic alterations and disease. Now, a team of researchers has mined "junk DNA" sequences to identify a non-protein-coding RNA whose expression is linked to ovarian cancer.
People with asthma often have a hard time dealing with respiratory viruses such as the flu or the common cold, and researchers have struggled to explain why. Now, the answer is becoming clearer.
Groundbreaking new research has discovered a new way to preserve the flexibility and resilience of the brain. The study reveals a nerve cell protective molecular target that is essential for brain plasticity.
People can become addicted to eating for its own sake but not to consuming specific foods such as those high in sugar or fat, new research suggests. An international team of scientists has found no strong evidence for people being addicted to the chemical substances in certain foods.
Scientists found that xenon, given within hours of the initial brain injury, limits brain damage and improves neurological outcomes in mice, both in the short term and long term.
New research published in the Proceedings of the National Academy of Science (PNAS) shows three genetic variants in humans that can account for a couple of IQ points– but before you get excited, these are only three variants out of likely thousands.
