A deficiency of taurine - a nutrient produced in the body and found in many foods - is a driver of aging in animals, according to a new study led by Columbia researchers and involving dozens of aging researchers around the world.

The same study also found that taurine supplements can slow down the aging process in worms, mice, and monkeys and can even extend the healthy lifespans of middle-aged mice by up to 12%.

In an international study co-led by UCLA, scientists have shown that a new targeted therapy drug can extend the amount of time people with a subtype of glioma are on treatment without their cancer worsening. The finding suggests a possible new treatment option for people with the slow-growing but deadly brain tumor.

The team found the drug vorasidenib more than doubled progression-free survival in people with recurrent grade 2 glioma with IDH1 and IDH2 mutations.

Since it was identified in 1984 as the cause of Acquired Immune Deficiency Syndrome (AIDS), the human immunodeficiency virus (HIV) has infected more than 80 million people and been responsible for some 40 million deaths worldwide, according to the World Health Organization (WHO). Currently, the WHO reports more than 38 million people globally live with the retrovirus, and each year, another 1 million new cases are diagnosed.

Why do some people develop Alzheimer's disease while others don't? And, even more puzzlingly, why do many individuals whose brains are chock-full of toxic amyloid aggregates - a telltale sign of Alzheimer's brain pathology - never go on to develop Alzheimer's-associated dementias?

University of Pittsburgh School of Medicine researchers appear to have found the answer.

Initial findings from a study of nearly 10,000 Americans, many of whom had COVID-19, have uncovered new details about long COVID, the post-infection set of conditions that can affect nearly every tissue and organ in the body. Clinical symptoms can vary and include fatigue, brain fog, and dizziness, and last for months or years after a person has COVID-19. The research team, funded by the National Institutes of Health, also found that long COVID was more common and severe in study participants infected before the 2021 Omicron variant.

Taking a daily multivitamin supplement can slow age-related memory decline, finds a large study led by researchers at Columbia University and Brigham and Women's Hospital/Harvard.

"Cognitive aging is a top health concern for older adults, and this study suggests that there may be a simple, inexpensive way to help older adults slow down memory decline,"

Scientists at St. Jude Children’s Research Hospital and the University of Texas Southwestern Medical Center studied the structure and function of a transporter involved in cancer and immunity. They captured six structures of the transporter, including when it was bound to an inhibitor, providing unprecedented insight into how it works. The findings, published in Cell, have implications for drug development.
