New research is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via a direct interface with the brain.
Scientists are enhancing the natural antioxidant properties of an element found in a car’s catalytic converter to make it useful for medical applications.
About a dozen years ago, scientists discovered that a hormone called ghrelin enhances appetite. Now, neuroscientists have discovered that when ghrelin is released during chronic stress makes the brain more vulnerable to traumatic events.
In the battle against antibiotic resistant bacteria, McMaster researchers have found resistance itself is a successful pathway for discovering new antibiotic drugs. "In essence, we’ve made resistance useful instead of a scary problem," said Gerry Wright, professor and scientific director of the Michael G. DeGroote Institute for Infectious Disease Research.
New research suggests that high levels of BPA, a chemical in many plastics and canned food linings, might raise the risk of miscarriage in women prone to that problem or having trouble getting pregnant. The work is not nearly enough to prove a link, but it adds to "the biological plausibility"that BPA might affect fertility and other aspects of health, said Dr. Linda Giudice.
Researchers imaged the brains of 30 young patients, 15 diagnosed with major depressive disorder (MDD) and 15 with bipolar disorder (BD). They found an activation of the putamen, a round structure at the base of the forebrain, which has a positive correlation with BD– and what could be the differentiating factor between BD and MDD.
Semprus BioSciences, a startup co-founded by two MIT alumni, is developing a novel biomaterial for implanted medical devices that permanently barricades troublesome microbes from the device’s surface.
Researchers at the Harvard Stem Cell Institute (HSCI) have published initial results of a Phase 1b human clinical trial of a therapeutic that could improve the success of blood stem cell transplantation.
A molecule originally implicated in DNA repair may also be a crucial factor in preventing tumors such as medulloblastoma, a type of childhood brain tumor, according to new research.
New research has shown that the stomach naturally produces more stem cells than previously realized, likely for repair of injuries from infections, digestive fluids and the foods we eat.
Scientists have discovered key details of a brain-to-body signaling circuit that, when activated by combined signals from the neurotransmitters serotonin and adrenaline, enables roundworms to lose weight independently of food intake.
Researchers have created a model that could help unlock what causes adenomyosis, a common gynecological disease that is a major contributor to women having to undergo hysterectomies.
Scientists have identified a set of compounds that may be used to treat MS in a new way: by boosting a population of progenitor cells that can in turn repair MS-damaged nerve fibers.
A protein increased by endurance exercise has been isolated and given to non-exercising mice, turning on genes that promote brain health and encourage the growth of new nerves involved in learning and memory, researchers say.
Researchers who previously identified a major pathway leading to brain cell death in mice, have used an orally-administered compound to block the pathway, and prevented neurodegeneration in the mice.
The global hookah-smoking trend is so pervasive that in some nations’ towns, 70% of university students do it daily; small kids do it; parents and kids do it together. Hookah cafes range from Karachi to Kansas, Iran to Iowa. The practice is escalating. The hookah has been around for 400 years. Yet among the 169 research papers on the topic listed with Pubmed, half were published since the start of 2012, 44 so far this year alone.
Findings from a study involving thousands of postmenopausal women suggest that women who use supplements containing both multivitamins and minerals have a 30 percent lower risk of dying from invasive breast cancer when compared with nonusers.
Scientists have discovered that the same protein that controls fat metabolism in the liver resides in the memory center of the brain (hippocampus) and controls memory and learning.
High levels of HDL have been linked to increased breast cancer risks and to enhanced cancer aggressiveness in animal experiments. Now, a team of researchers has shown that an HDL receptor found on breast cancer cells may be responsible for this effect.
The federal Centers for Disease Control and Prevention say a rare amoeba, Naegleria fowleri, that caused the August death of a child in south Louisiana has been found in five locations in a north Louisiana water system.
Researchers have pinpointed a site in the brain that plays an important role in the subconscious recognition of which way is straight up and which way is down. The finding may help account for some causes of spatial disorientation and dizziness.
Scientists have discovered, by studying the genetics of two families severely affected by eating disorders, two gene mutations that are associated with increased risk of developing eating disorders.
In a new study researchers demonstrate that some chemical compounds found in marijuana may be used to help treat MS-like diseases by regulating inflammation to protect the nervous system and its functions.
A world-first human study to assess the impact of sunscreen at the molecular level has shown that sunscreen provides 100 percent protection against all three forms of skin cancer, and it also shields the important p53 gene, a gene that works to prevent cancer.
New research has revealed a set of cells in the fruit fly brain that respond specifically to food odors. The degree to which these neurons respond when the fly is presented different food odors can predict how much the flies will like a given odor.
