Study highlights barriers to genetic testing for Black children

Studies have shown that Black children with serious illnesses are less likely than white children to obtain crucial genetic testing necessary to guide treatment decisions, but the reasons for this disparity have not been fully understood. A new study from Washington University School of Medicine in St. Louis focused on children with neurological conditions finds […]

Patient defies genetic fate to avoid Alzheimer’s

Remarkably, Doug Whitney, 75, has escaped genetic destiny. Like many members of his family, Whitney inherited a rare genetic mutation that all but guarantees he would develop early-onset Alzheimer’s disease. But Whitney, whose relatives first showed symptoms of cognitive decline in their early 50s, remains mentally sharp with no signs of the devastating disease, and […]

Engineering better sleep

Clock on a wood surface with sunrise behind green-leaf woody space.

Complex biological networks control a range of functions in the human body from metabolic processes to the sleep cycle. Though scientists have ever-increasing volumes of data about the effects these complex systems produce, fully describing them mathematically has proven difficult. Without a firm understanding, effective interventions continue to be elusive, leaving more than 50 million […]

Brain structure differences provide clues to substance use risks

When studying substance use disorders, scientists had thought some of the effects on the brain could stem from use of the substances themselves: People start drinking alcohol in early teens, that alcohol has a neurotoxic effect on the developing brain that begets more alcohol drinking, and a similar dynamic occurs with other substances. But research […]

Scientists are trying to understand how cannabis may affect long-term neurodevelopment when people were exposed to it in the womb. Previous work by Washington University in St. Louis researchers Sarah Paul and David Baranger in the Behavioral Research and Imaging Neurogenetics (BRAIN) lab led by Ryan Bogdan, PhD, found associations between prenatal cannabis exposure and potential mental health conditions in childhood […]

The brain has a waste removal system and scientists are figuring out how it works

The brain needs to flush out waste products to stay healthy and fend off conditions like Alzheimer’s disease. Scientists are beginning to understand how the the brain’s waste removal system works. [Transcript] A MARTÍNEZ, HOST: Turns out the brain needs regular cleaning. Otherwise, it gets clogged up with waste products, including some associated with diseases […]

New technology allows researchers to precisely, flexibly modulate brain

Human brain diseases, such as Parkinson’s disease, involve damage in more than one region of the brain, requiring technology that could precisely and flexibly address all affected regions simultaneously. Researchers at Washington University in St. Louis have developed a noninvasive technology combining a holographic acoustic device with genetic engineering that allows them to precisely target […]

Gut bacteria boost immune response to fight tumors

Roughly one in five cancer patients benefits from immunotherapy – a treatment that harnesses the immune system to fight cancer. Such an approach to beating cancer has seen significant success in lung cancer and melanoma, among others. Optimistic about its potential, researchers are exploring strategies to improve immunotherapy for cancers that don’t respond well to […]

Some brain tumors may be linked to head injury, mouse study suggests

A study in mice by researchers at the School of Medicine indicates that brain injury can lead to brain tumors in susceptible individuals. For this study, they used mice that model people with neurofibromatosis type 1 (NF1), a genetic disorder that causes brain tumors. The study showed that molecules released by injured neurons set off […]

Immunotherapy for Alzheimer’s disease shows promise in mouse study

Alzheimer’s disease starts with a sticky protein called amyloid beta that builds up into plaques in the brain, setting off a chain of events that results in brain atrophy and cognitive decline. The new generation of Alzheimer’s drugs — the first proven to change the course of the disease — work by tagging amyloid for […]

NIH funds study of ultrasound with genetics to treat brain disorders

Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the […]

Tau-based biomarker tracks Alzheimer’s progression

Two pathologies drive the progression of Alzheimer’s disease. Early on, amyloid beta plaques lead the way, but around the time cognitive symptoms arise, tau tangles take over as the driving force and cognition steadily declines. Tracking the course of the disease in individual patients has been challenging because there’s been no easy way to measure […]

The Asturias awards, among the most prestigious honors in the Spanish-speaking world, are presented annually in eight categories. The awards are designed to recognize exceptional scientific, technical, cultural, […]

Induction of a torpor-like state with ultrasound

Some mammals and birds have a clever way to preserve energy and heat by going into torpor, during which their body temperature and metabolic rate drop to allow them to survive potentially fatal conditions in the environment, such as extreme cold or lack of food. While a similar condition was proposed for scientists making flights […]

Findings may lead to improved insulin-secreting cells derived from stem cells

Diabetes researchers at Washington University School of Medicine in St. Louis have uncovered at least one reason insulin-secreting cells made from stem cells in the lab don’t work as well as natural cells. The discovery could help speed progress toward making insulin-secreting cells — called islet beta cells — more effective in the treatment of […]

The Bagnall lab studies motor control […]

Insight into brain’s waste clearing system may shed light on brain diseases

Like the lymphatic system in the body, the glymphatic system in the brain clears metabolic waste and distributes nutrients and other important compounds. Impairments in this system may contribute to brain diseases, such as neurodegenerative diseases and stroke. A team of researchers in the McKelvey School of Engineering at Washington University in St. Louis has […]
