Very slow brain waves, long considered an artifact of brain scanning techniques, may be more important than anyone had realized. Researchers at Washington University School of Medicine in St. Louis have found that very slow waves are directly linked to state of consciousness and may be involved in coordinating activity across distant brain regions.
Scientists have previously shown that when one animal watches another performing a motor task, such as reaching for food, mirror neurons in the motor cortex of the observer's brain start firing as though the observer were also reaching for food.
New Duke research appearing March 29 in the journal Scientific Reports suggests mirroring in monkeys is also influenced by social factors, such as proximity to other animals, social hierarchy and competition for food.
Dining out more at restaurants, cafeterias and fast-food outlets may boost total levels of potentially health-harming chemicals called phthalates in the body, according to a study out today.
In response to repeated calls for an integrated emergency care system in the U.S., the University of Pittsburgh rose to the challenge and divided the nation into hundreds of referral regions that describe how patients access advanced care, in a way that respects geopolitical borders.
Doctors recommend against taking antibiotics for viral infections because they don't work – antibiotics don't kill viruses – and do promote antibiotic resistance. A new study from Washington University School of Medicine in St. Louis suggests another reason to avoid the pills: Taking antibiotics increases susceptibility to subsequent viral infection, at least in mice.
Head and neck cancers (squamous cell carcinomas or HNSCC) represent more than half-a-million cases and 300,000 deaths a year, making them the sixth-leading cancer worldwide, according to the World Health Organization.
A Case Western Reserve University-led research team will analyze computerized images of tissue samples for patterns which could become "biomarkers," or predictors, for determining relative risk for recurrence in one particularly common type of head and neck cancers.
A systematic study of seven antioxidants commonly taken by or suggested to benefit children and adults affected with mitochondrial disease provides intriguing clues that at least two compounds should be further evaluated in clinical trials. There are currently no proven, effective treatments for mitochondrial disease.
New research from Roswell Park Comprehensive Cancer Center and MimiVax LLC, published in Clinical Cancer Research, shows that survivin — one of the most commonly occurring molecules in cancer cells — may be an attractive target for a broad range of immunotherapy approaches, including CAR T.
Plaques of a brain protein called amyloid beta are a characteristic sign of Alzheimer's disease. But nestled within the plaques are small amounts of another Alzheimer’s protein: APOE. Now, researchers at Washington University School of Medicine have shown that an antibody not only targets APOE for removal but sweeps away plaques in mice. The findings could lead to a way to halt the brain damage triggered by amyloid plaques while the disease is still in its early stages, perhaps before symptoms appear.
A public health research team at Washington University in St. Louis has taken one of the most effective diabetes intervention programs and made it more accessible by partnering with an existing home-visit organization.

Researchers at Tufts University have created a genetically modified yeast that can more efficiently consume a novel nutrient, xylose, enabling the yeast to grow faster and to higher cell densities, raising the prospect of a significantly faster path toward the design of new synthetic organisms for industrial applications, according to a study published today in Nature Communications.
Researchers have developed a stretchable, flexible patch that could make it easier to perform ultrasound imaging on odd-shaped structures, such as engine parts, turbines, reactor pipe elbows and railroad tracks—objects that are difficult to examine using conventional ultrasound equipment. The ultrasound patch is a versatile and more convenient tool to inspect machine and building parts for defects and damage deep below the surface.
With the ability to leech heavy metals from the environment and digest a potent greenhouse gas, methanotrophic bacteria pull double duty when it comes to cleaning up the environment. But before researchers can explore potential conservation applications, they first must better understand the bacteria's basic physiological processes. Amy C. Rosenzweig's laboratory at Northwestern University has identified two never-before-studied proteins, called MbnB and MbnC, as partially responsible for the bacteria's inner workings.
A well-studied enzyme called SIRT1 declines in the blood vessels with age and restoring it reverses the effects of vascular aging in mice. After receiving a supplement called NMN, older mice showed increased capillary density, blood flow, mobility, and endurance
-Scientists identify mechanism behind vascular aging, muscle demise in mice.
-Treatment with chemical compounds reversed vascular aging, stimulated blood vessel growth and blood flow, boosted exercise capacity in aging animals.
-Findings set the stage for therapies in humans to stave off a range of conditions linked to vascular aging.
Cervical fluid samples gathered during routine Papanicolaou (Pap) tests are the basis of a new screening test for endometrial and ovarian cancers developed by researchers at the Johns Hopkins Kimmel Cancer Center.
Miniaturized sensors when mounted directly on a tooth and communicating wirelessly with a mobile device, can transmit information on sugars, alcohol and salt. Researchers note that future adaptations of these sensors could enable the detection and recording of a wide range of nutrients, chemicals and physiological states.
Alzheimer's disease is characterized by clumps of two proteins – amyloid beta and tau – in the brain, but the link between the two has never been entirely clear. Now, researchers at Washington University School of Medicine in St. Louis have shown that people with more amyloid in the brain produce more tau, which could lead to new treatments for the disease based on targeting the production of tau.
Researchers have discovered a “missing mutation” in severe infant epilepsy—long-suspected genetic changes that might trigger overactive, brain-damaging electrical signaling leading to seizures. They also found early indications that specific anti-seizure medications might prevent disabling brain injury.
In a striking new finding, researchers at the UC Davis MIND Institute found that typically-developing children gain more neurons in a region of the brain that governs social and emotional behavior, the amygdala, as they become adults. This phenomenon does not happen in people with autism spectrum disorder (ASD). Instead, children with ASD have too many neurons early on and then appear to lose those neurons as they become adults. The findings were published today in the journal Proceedings of the National Academy of Sciences (PNAS).
Tobacco-related disease is especially prevalent among African-American men. This grant provides more multidisciplinary opportunities for UAB faculty to provide solutions for tobacco cessation. Preliminary data shows that 39.9 percent of African-American men between 19 and 30 years of age in rural Alabama counties smoke cigarettes.

Tissue-engineering technique based on a novel cylindrical scaffolding design seeded with collagen-secreting cells yields grafts for articular cartilage repair with superior mechanical strength and durability.
Children with mild to moderate asthma do not benefit from a common practice of increasing their inhaled steroids at the first signs of an asthma exacerbation, according to clinical trial results published in The New England Journal of Medicine. Researchers found short-term increases in inhaled steroids did not prevent attacks in children aged 5 to 11, and may even slow a child’s growth.
A first of its kind study shows typical interruptions experienced by on-call radiologists do not reduce diagnostic accuracy but do change what they look at and increase the amount of time spent on a case.
The implication of the finding is that as radiologists contend with an increasing number of workplace interruptions, they must either process fewer cases or work longer hours — both of which have adverse effects in terms of patient outcomes, said Trafton Drew, the study's lead author. They also may spend more time looking at dictation screens than reviewing medical images.
Scientists are bringing precision medicine to rheumatoid arthritis for the first time by using genetic profiling of joint tissue to see which drugs will work for which patients, reports a new Northwestern Medicine multi-site study.In the near future, patients won’t have to waste time and be disappointed with months of ineffective therapy, scientists said.
It defies conventional wisdom about semiconductors. It's baffling that it even works. It eludes physics models that try to explain it. This newly tested class of light-emitting semiconductors is so easy to produce from solution that it could be painted onto surfaces to light up our future in myriad colors shining from affordable lasers, LEDs, and even window glass.
In a study that has implications for humans with inflammatory diseases, researchers from Case Western Reserve University School of Medicine and colleagues have found that, given over a six-week period, the artificial sweetener sucralose, known by the brand name Splenda, worsens gut inflammation in mice with Crohn’s-like disease, but had no substantive effect on those without the condition. Crohn's disease is an inflammatory bowel disease of the digestive tract, which can lead to abdominal pain, severe diarrhea, bloody stools, weight loss, and fatigue. About 10-15 percent of human patients report that sweeteners worsen their disease.
Researchers at Vanderbilt University Medical Center have found a way to search genetic data in electronic health records to identify undiagnosed genetic diseases in large populations so treatments can be tailored to the actual cause of the illness.
This week, thousands of graduating medical students around the country will find out where they’ll head next, to start their residency training. But a new study gives the first objective evidence of the heavy toll that the first year of residency can take on their sleep, physical activity and mood.
Adults who have undergone successful cancer treatment years or decades previously become fatigued more quickly than their peers who don’t have cancer histories, according to a new study in the journal Cancer from scientists at Johns Hopkins Bloomberg School of Public Health.
UCLA scientists have developed a new method that utilizes microscopic splinter-like structures called “nanospears” for the targeted delivery of biomolecules such as genes straight to patient cells. These magnetically guided nanostructures could enable gene therapies that are safer, faster and more cost-effective.
