A probiotic that prevents obesity could be on the horizon. Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice.
People with Type 2 diabetes who eat a diet high in salt face twice the risk of developing...
Vitamin D-deficient individuals are twice as likely to be diagnosed with schizophrenia as people...
Scientists have linked more than 100 spots in our DNA to the risk of developing schizophrenia,...
A new device, based on a fly's freakishly acute hearing, may find applications in futuristic hearing aids and military technology.
The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of researchers has designed a way to snip out the integrated HIV-1 genes for good.
Researchers have developed a powerful new single-cell technique to help investigate how the environment affects our development and the traits we inherit from our parents. The technique can be used to map all of the epigenetic marks on the DNA within a single cell.
Lack of sleep, already considered a public health epidemic, can also lead to errors in memory. A study found participants deprived of a night’s sleep were more likely to flub the details of a simulated burglary they were shown in a series of images.
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. A new study reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons.
The seriousness of disease often results from the strength of immune response, rather than with the virus, itself. Turning down that response, rather than attacking the virus, might be a better way to reduce that severity.
Dysfunction in dopamine signaling profoundly changes the activity level of about 2,000 genes in the brain’s prefrontal cortex and may be an underlying cause of certain complex neuropsychiatric disorders, such as schizophrenia, according to new research.
Veterans, medical marijuana activists and scientists welcomed the first federally approved research into pot as a treatment for post-traumatic stress disorder. But their hopes for the research were dashed when the Univ. of Arizona fired researcher Suzanne Sisley, who undertook the study after clearing four years of bureaucratic hurdles.
Too much dietary fat is bad for the heart, but the right kind of fat— unsaturated dietary fatty acids— keeps the heart healthy.
Visions of chlorine-drenched chickens and the prospect of genetically modified "Frankenfood" invading dinner tables across the European Union are proving serious impediments to the signing of a sweeping free trade agreement between the U.S. and the 28-country bloc.
Cancer has left its “footprint” on our evolution, according to a study that examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.
The danger of reporting findings before peer review is that scientists often can’t talk about the details of their research, which can lead to hype or fear in the media.
Many human studies have shown that long-term alcohol abuse causes brain damage and increases the risk of dementia. The new study found that in brain cells exposed to high levels of alcohol, a fish oil compound protected against inflammation and neuronal cell death.
In mice with diet-induced diabetes— the equivalent of type 2 diabetes in humans— a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days. The discovery could lead to a new generation of safer, more effective diabetes drugs.
A biochemist’s discovery of a class of anti-viral small molecules that target the function of a virus DNA hidden in the infected livers of hepatitis B patients may lead to a cure for this viral infection that kills more than 600,000 people annually.
A drug that is commonly used for arthritis has been shown to slow the progression of Alzheimer’s. A small randomized control study tested the drug Etanercept on patients with mild to moderate Alzheimer’s. Results showed that patients who were given Etanercept did not get any worse during the six month follow up compared to those on the placebo, who did decline.
Genetics could be the key to explaining nations’ levels of happiness. Economists have looked at why certain countries top the world happiness rankings. They found that, the closer a nation is to the genetic makeup of Denmark, the happier that country is.
Even mild traumatic brain injury may cause brain damage and thinking and memory problems, according to a study that found that, compared to people with no brain injury, those with injuries had brain damage in brain white matter.
The same federal scientist who recently found forgotten samples of smallpox at a federal lab also uncovered more than 300 additional vials, many bearing the names of highly contagious viruses and bacteria such as dengue, influenza and rickettsia.
High body mass index is associated with multiple cardiovascular diseases. However, investigators have now confirmed that the risk of total mortality, cardiovascular mortality and myocardial infarction is highest among underweight patients, while cardiovascular mortality is lowest among overweight patients.
Cardiologists have developed a minimally invasive gene transplant procedure that changes unspecialized heart cells into “biological pacemaker” cells that keep the heart steadily beating. The procedure is the result of a dozen years of research.
Increasing globalization and transportation of food products across the globe means we are all increasingly at risk of catching something unwanted from our favorite foods. Now, experts have ranked the most damaging food-borne parasites according to number of cases, global distribution and health impact.
Scientists may have found a way to imprison the malaria parasite in its protective chamber inside red blood cells. This causes it to stop growing and die.
Chemists and students in science and engineering have created a new type of chemical test, or assay, that’s inexpensive, simple and can tell whether or not one of the primary drugs being used to treat malaria is genuine– an enormous and deadly problem in the developing world.
