On the computer screens, the mouse brain is shown from several angles. Then you click, and a small area of the brain is highlighted in color. With the next click, something happens to the color markers. ...

A novel quantitative PET- and MRI-based imaging approach can objectively identify a recently recognized type of dementia—limbic-predominant age-related TDP-43 encephalopathy, or LATE—that is often ...

It's widely known that breastfeeding impacts the health of both mother and child, but the underlying biology that leads to these effects has been understudied. In a review article published in Trends ...

A massive study of more than 270,000 people has uncovered a surprising link between a common amino acid and how long men live. Researchers found that higher levels of tyrosine—an amino acid found in protein-rich foods and often marketed as a focus-boosting…

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal scaffold. When this structure is disrupted, cells fail to grow…

The Old Irish Goat isn’t just part of folklore — it’s genetically linked to goats that lived in Ireland 3,000 years ago. Scientists analyzed ancient remains and discovered that today’s rare breed shares its strongest DNA ties with Late Bronze Age animals.…

Worrying about getting older—especially fearing future health problems—may actually speed up aging at the cellular level, according to new research from NYU. In a study of more than 700 women, those who felt more anxious about aging showed signs of faster…

Popular acid reflux drugs such as Prilosec, Nexium, and Protonix may carry hidden risks when taken long term. A new study found that extended use disrupted iron and calcium levels in rats, changes associated with anemia and osteoporosis risk. Researchers…

A new genetic study suggests that obesity and high blood pressure may play a direct role in causing dementia, not just increasing the risk. By analyzing data from large populations in Denmark and the U.K., researchers found strong evidence that higher body…

Close to 56,000 pounds of frozen blueberries have been recalled after testing raised concerns about possible Listeria monocytogenes contamination, according to the U.S. Food and Drug Administration (FDA).

A team of scientists from the U.S. has discovered that acetate, a simple molecule involved in how our bodies create energy, can significantly increase long-term memory in female mice. The researchers ...

A large French study tracking more than 100,000 people over a decade has found that higher consumption of certain food preservatives—commonly found in processed foods and drinks—is linked to a modestly higher cancer risk. While many preservatives showed no…

Carbohydrates don’t just fuel the body—they may also influence how the brain ages. A large long-term study found that diets high in fast-acting carbs that rapidly raise blood sugar were linked to a higher risk of dementia. People who ate more low-glycemic…

In a new study published in Communications Biology, Houston Methodist researchers led by Sonia Villapol, Ph.D., found that short-term antibiotic treatment significantly reduced neuroinflammation and neurodegeneration ...

TB in Persons Living with HIV Initiating ART

Consumers can protect their skin from damaging ultraviolet (UV) light rays for as little as $40 a year—or as much as $1,400 a year—depending on how expensive a sunscreen they buy and how much of their ...

Human metabolism is regulated by internal clocks, the so-called circadian rhythms. Many processes, such as sugar uptake, fat burning, or hormone release, oscillate during the day, i.e., they fluctuate ...

An autoimmune disorder that affects the thyroid gland, called autoimmune hypothyroidism (AIHT), is the most common autoimmune disease, yet it remains largely understudied. New research from scientists ...
