A lone genetic mutation can cause a life-changing disorder with effects on multiple body systems. Lysosomal storage diseases, for example, of which there are dozens, arise due to single mutations that affect production of critical enzymes required to metabolize large molecules in cells. These disorders affect multiple organs including, notably, the brain, causing intellectual disability […]
As the number of COVID-19 patient records grows, researchers are meticulously combing through the data, searching for a better understanding of the virus and what we can expect in the months and years ahead. What is now of increasing concern in health care is the realization that the virus can not only be severe, but […]
A mouse model of glioblastoma, an aggressive type of cancer that can occur in the brain, suggests that this recalcitrant cancer originates from a pool of stem cells that can be a significant distance away from the resulting tumors. The findings of a new study, led by Children’s National Hospital researchers and published July 22 […]
The anxiety you may be feeling right now in the midst of the COVID-19 pandemic stems back to our prehistoric need to survive. Biologists have explored this principle for decades. Those breathing techniques that your mobile app, HR office or best friend might be recommending? They can help—psychology studies have proven this. But what’s happening […]
The eyes have a surprise. For decades, biology textbooks have stated that eyes communicate with the brain exclusively through one type of signaling pathway. But a new discovery shows that some retinal neurons take a road less traveled. New research, led by Northwestern University, has found that a subset of retinal neurons sends inhibitory signals […]
Michelle Money is evaluating her next steps after her 15-year-old daughter Brielle’s brain pressure went up after she underwent surgery following a skateboarding accident. “Today has been a week [since the accident] and if we can’t get her numbers stabilized than we are going to have to put her into a deeper coma that has […]
A new study by members of the Cumming School of Medicine (CSM) at the University of Calgary finds niacin, commonly called vitamin B3, combined with chemotherapy can help immune cells attack glioblastoma (a type of brain tumor), dramatically slowing progression of the disease, in mice. The results published in Science Translational Medicine found the lifespan […]
The media is replete with COVID-19 stories about people clearing supermarket shelves—and the backlash against them. Have people gone mad? How can one individual be overfilling his own cart, while shaming others who are doing the same? As a behavioral neuroscientist who has studied hoarding behavior for 25 years, I can tell you that this […]
University of Iowa neuroscientists have identified a specific area of the brain involved in the loss of breathing that occurs during a seizure. The findings, published in JCI Insight on March 12, could have important implications for predicting, or even treating and preventing sudden unexpected death due to epilepsy (SUDEP). Although it has been known […]
For over a century, Alzheimer’s disease has confounded all attempts to treat it. But in recent years, perplexing experiments using flickering light have shown promise. Now, researchers have tapped into how the flicker may work. They discovered in the lab that the exposure to light pulsing at 40 hertz—40 beats per second—causes brains to release […]
