Aging may change some brain cells more than others

January 2, 2025 Based on new brain mapping research funded by the National Institutes of Health (NIH), scientists have discovered that not all cell types in the brain age in the same way. They found that some cells, such as a small group of hormone-controlling cells, may undergo more age-related changes in genetic activity than others. The results, published in Nature, support the idea that some cells are more sensitive to the aging process and aging brain disorders than others.

NIH-led scientific team defines elements of brain-based visual impairment in children

November 19, 2024 Experts convened by the National Institutes of Health (NIH) have identified five elements of a brain-based condition that has emerged as a leading cause of vision impairment starting in childhood in the United States and other industrialized nations. Known as cerebral (or cortical) visual impairment (CVI), some estimates suggest that at least 3% of primary school children exhibit CVI-related visual problems, which vary, but may include difficulty visually searching for an object or person or understanding a scene involving complex motion. Their report, based on evidence and expert opinion, was published today in Ophthalmology.

Researchers uncover new role of mutant proteins in some of the deadliest cancers

November 12, 2024 Researchers at the National Institutes of Health (NIH) and their collaborators have discovered a new way in which RAS genes, which are commonly mutated in cancer, may drive tumor growth beyond their well-known role in signaling at the cell surface. Mutant RAS, they found, helps to kick off a series of events involving the transport of specific nuclear proteins that lead to uncontrolled tumor growth, according to a study published Nov. 11, 2024, in Nature Cancer.

Salivary Enzyme Behind Our Carb Cravings May Have Unexpectedly Ancient History

November 7, 2024 Digestion involves much more than just your stomach. The digestive process that fuels your body begins in your mouth each time you take a bite of food and chew. An enzyme in your saliva, called amylase, then starts to break down complex carbohydrates—or starches found in many fruits, vegetables, and grains—into simpler sugars to give you their sweet flavor followed by a burst of energy.

Why protective antibodies fade after COVID-19 vaccines

October 29, 2024 Researchers found that current COVID-19 vaccines fail to generate mature and durable antibody-producing cells in the bone marrow. The findings could help explain why protection tends to decline over time. Better understanding of long-term immune responses could lead to improved vaccines that provide enduring protection.

Alzheimer’s disease may damage the brain in two phases

October 15, 2024 Alzheimer’s disease may damage the brain in two distinct phases, based on new research funded by the National Institutes of Health (NIH) using sophisticated brain mapping tools. According to researchers who discovered this new view, the first, early phase happens slowly and silently — before people experience memory problems — harming just a few vulnerable cell types. In contrast, the second, late phase causes damage that is more widely destructive and coincides with the appearance of symptoms and the rapid accumulation of plaques, tangles, and other Alzheimer’s hallmarks.

After a rocky debut for new RSV tools, hopes are high as a new season approaches

October 4, 2024 RSV is a common virus that causes cold-like symptoms; it infects people at any age. But while most adults would probably write off an RSV infection as just a nasty cold, the illness triggered in older adults and babies is typically more severe. That is particularly true in young babies, whose lungs are still developing.

Millions of Americans want to quit smoking. Critics say drugmakers and the FDA are failing them

September 23, 2024 Of the roughly 15 million Americans who tried to quit smoking in 2022, 5 in 6 failed. It’s a jarring statistic — and an indictment of the treatment options for an addiction that kills 480,000 people in the U.S. each year.

The smoking-cessation drugs on the market don’t work well for the majority of people, and they come with side effects and reputations that keep some smokers from ever trying them. Despite this, there hasn’t been a new class of drug approved for the condition in nearly two decades.

Doctors use problematic race-based algorithms to guide care every day. Why are they so hard to change?

September 3, 2024 Pediatrician Alexandra Epee-Bounya had had enough. In her 20 years caring for children in Boston, she had seen hundreds of kids with suspected urinary tract infections. Each time, she’d turn to a calculator, used by all Boston Children’s Hospital clinicians, to judge the youngest children’s risk. Did the infant have a high fever? Add a point. Was she a girl? Add two points. 

As she went down the list, one of the factors tripped her up every time: Was the child Black? If not, add a point. The more points, the higher the risk of a UTI, which meant the child would get follow up testing. How could it be that the color of a child’s skin dictated their care?

NIH researchers discover potential therapeutic target for degenerative eye disease

Study reveals cellular pathology of “dry” AMD.

July 26, 2024 Researchers from the National Institutes of Health (NIH) have discovered the source of dysfunction in the process whereby cells in the eye's retina remove waste.

From NIH

A report by scientists at NIH and Johns Hopkins University, Baltimore, details how alterations in a factor called AKT2 affects the function of organelles called lysosomes and results in the production of deposits in the retina called drusen, a hallmark sign of dry age-related macular degeneration (AMD). According to the researchers, the findings suggest drusen formation is a downstream effect of AKT2-related lysosome dysfunction and points to a new target for therapeutic intervention.
