Research on new, rapid screening test identifies potential therapies against drug-resistant bacteria
Researchers have created a new way to identify drugs and drug combinations that may potentially be useful in combating infections that are resistant to many different antibiotics. »
Brazil ranks tenth for preterm birth, with approximately 300 thousand premature babies every year—11.7% of the total births in the country. Most cases stem from teenage or late pregnancies, precarious prenatal care, or illnesses afflicting the mother. »
Drugs that are used to treat a number of autoimmune diseases appear to treat symptoms of depression as well. The finding of a new study suggests that anti-inflammatories, as they are known, may take their place alongside conventional treatments to help people with depression. »
Two experimental Zika virus DNA vaccines developed by NIH scientists protected monkeys against Zika infection. »
Researchers identified a set of heat-sensing brain cells in mice that prompt both nervous system and behavioral changes that cool the body. »
Certain DNA changes can better predict a person’s life expectancy than traditional risk factors such as age. »
Being overweight is not good for your body, and new research suggests it’s not good for your brain either. »
A research team from Boston Children’s Hospital investigated an easier way to deliver ear infection medication. They engineered an antibiotic-containing gel that can be inserted directly inside the ear canal. »
Cognitive function improves with aerobic exercise, but not for people exposed to high levels of mercury before birth. »
Our digestive tracts are home to trillions of microbes—including bacteria, fungi, and viruses. This microbial community, known as the microbiota, plays a role in illness and health. »
Blood delivers nutrients and oxygen to all parts of your body. High blood pressure, or hypertension, is a common disease in which blood flows through blood vessels at higher than normal pressures. »
Extreme hot or cold temperatures during pregnancy may increase the risk of preterm birth, according to study by researchers at the National Institutes of Health. »
Researchers have identified a mechanism in mice by which anticancer immune responses are inhibited within the lungs, a common site of metastasis for many cancers. »
Researchers tested peanut oral immunotherapy in preschool-aged children with a newly diagnosed peanut allergy. After the treatment, most children could eat peanut-containing foods without an allergic reaction. »
A team from Washington University School of Medicine in St. Louis, previously engineered a scaffold to guide stem cells into cartilage-producing cells. »
Scientists identified a molecule that restores the activity of a dysfunctional enzyme tied to both Gaucher disease and Parkinson’s disease. These findings suggest a new avenue to explore for treating these disorders. »
Researchers have mapped 180 distinct areas in our brain’s outer mantle, or cortex – more than twice the number previously known. »
A study in mice shows for the first time that high-contrast visual stimulation can help damaged retinal neurons regrow optic nerve fibers, otherwise known as retinal ganglion cell axons. »
A recent study revealed biomarker combinations in urine that are unique to prostate cancer and 2 of its stages. The findings suggest a noninvasive approach to diagnosing prostate cancer and assessing tumor progression. »
Researchers found that blood levels of seafood- and plant-based omega-3 fatty acids were associated with a lower risk of dying from heart attacks. »
An epigenomic analysis of rheumatoid arthritis in knee and hip joints revealed unique patterns that suggest disease mechanisms may differ from joint to joint. The findings could open the door to development of more effective, personalized therapies for rheumatoid arthritis. »
Proper maternal folate levels during pregnancy may protect children from a future risk of obesity, especially those born to obese mothers, according to a study. »
Introducing peanut-containing foods during infancy as a peanut allergy prevention strategy does not compromise the duration of breastfeeding or affect children’s growth and nutritional intakes, new findings show. »
Beta-amyloid, a protein implicated in Alzheimer’s disease, appears to help protect mice and worms from infection with bacteria or fungi. The results suggest that Alzheimer’s disease may result from certain infections. If validated, the findings could lead to novel approaches to prevent the disease. »
Rare tumors called pheochromocytomas and paragangliomas may cause the same symptoms as attention deficit hyperactivity disorder (ADHD) in children, leading to inappropriate treatment that could worsen their symptoms and potentially endanger their health. »
A team of scientists investigated antimicrobial gene activation during infection to better understand the body’s immune response to microbes. »
Leisure-time physical activity has many health benefits. In addition to a reduced risk for heart disease, increased physical activity has been associated with a lower risk for colon, breast, and endometrial cancers. »
Researchers found that a healthy person’s skin microbes change remarkably little over time. The stability, however, varies across body sites. »
Researchers determined that microtubules, a type of molecular “strut,” play a key role in regulating contractile function in mouse and rat heart cells. »
Researchers with the National Human Genome Research Institute have collaborated with physicians and medical geneticists around the world to create the Atlas of Human Malformation Syndromes in Diverse Populations. »
The long-held approach to predicting seasonal influenza vaccine effectiveness may need to be revisited, new research suggests. »
Sticking to a healthy diet in the years after pregnancy may reduce the risk of high blood pressure among women who had pregnancy-related (gestational) diabetes. »
The Zika virus surface is similar to that of dengue and related viruses at the near-atomic level, researchers found, but with a notable difference. »
Researchers have sequenced nearly the entire genome of human, mouse and rat Pneumocystis. This organism causes a life-threatening pneumonia in immunosuppressed hosts. »
Researchers designed and tested a system that delivered nanometer-sized particles of a cancer drug to tumors in mice, improving survival. »
A woman is more likely to miscarry if she and her partner drink more than two caffeinated beverages a day during the weeks leading up to conception. »
Higher levels of HDL have been associated with a lower risk of cardiovascular disease. However, pharmaceutical approaches to reduce heart disease risk by raising HDL levels have had disappointing results. »
Study provides evidence for the existence of a non-opioid process in the brain to reduce pain through mindfulness meditation. »
Scientists identified the mechanism behind genetic variations that were linked to schizophrenia in previous genomic studies. »
The benefits of regularly consuming peanut-containing foods early in life to prevent the development of peanut allergy persist even after stopping peanut consumption for one year. »
Exposing babies delivered by C-section to fluids from the mother’s birth canal enriched the babies’ microbes to levels more typical of babies born vaginally. »

Researchers found genetic variations in the Inuit of Greenland that reflect adaptations to their specific diet and climate. »
The inflammatory eye disorder autoimmune uveitis occurs when a person’s immune system goes awry, attacking proteins in the eye. What spurs this response is a mystery, but now a study on mice suggests that bacteria in the gut may provide a kind of training ground for immune cells to attack the eye. »
