Durable End to AIDS Will Require HIV Vaccine Development
February 6, 2024 12:58 pm | CommentsBroader global access to lifesaving antiretroviral therapies and wider implementation of proven HIV prevention strategies could potentially control and perhaps end the HIV/AIDS pandemic. However, a safe and at least moderately effective HIV vaccine is needed to reach this goal more expeditiously and in a more sustainable way, according to a new commentary from Anthony S. Fauci, MD, director of the NIAID.
Study Finds Dramatic Rise in Skin Cancer among Middle-Aged Adults
February 5, 2024 7:16 am | CommentsA new Mayo Clinic study found that among middle-aged men and women, 40 to 60 years old, the overall incidence of skin cancer increased nearly eightfold between 1970 and 2009. There has been widespread concern in recent years about the rising incidence of melanoma, which affects 75,000 Americans annually and results in nearly 9,000 deaths. Few studies, however, have investigated which age brackets of adults are most at risk.
NIH Study Offers Insight into Why Cancer Incidence Increases with Age
February 4, 2024 1:30 pm | CommentsThe accumulation of age-associated changes in a biochemical process that helps control genes may be responsible for some of the increased risk of cancer seen in older people, according to a National Institutes of Health and National Institute of Environmental Health Sciences study.
Liver Tumors Found in Mice Exposed to BPA
February 3, 2024 11:08 am | CommentsIn one of the first studies to show a significant association between BPA and cancer development, University of Michigan School of Public Health researchers have found liver tumors in mice exposed to the chemical via their mothers during gestation and nursing.
Obesity-Induced Fatty Liver Disease Reversed In Mice
February 3, 2024 10:57 am | CommentsJohns Hopkins researchers have discovered that valproic acid, a widely prescribed drug for treating epilepsy, has the additional benefits of reducing fat accumulation in the liver and lowering blood sugar levels in the blood of obese mice.
Cell Cycle Speed is Key to Making Aging Cells Young Again
January 30, 2024 1:46 pm | CommentsA fundamental axiom of biology used to be that cell fate is a one-way street—once a cell commits to becoming muscle, skin, or blood it always remains muscle, skin, or blood cell. That belief was upended in the past decade when a Japanese scientist introduced four simple factors into skin cells and returned them to an embryonic-like state, capable of becoming of almost any cell type in the body.
Scientists Reveal Cause of One of the Most Devastating Pandemics in Human History
January 28, 2024 2:08 pm | CommentsAn international team of scientists has discovered that two of the world’s most devastating plagues – the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe—were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s.
3-D Cell Imaging Technique Requires No Dye
January 23, 2024 12:51 pm | CommentsLiving cells are ready for their close-ups, thanks to a new imaging technique that needs no dyes or other chemicals, yet renders high-resolution, three-dimensional, quantitative imagery of cells and their internal structures.
Benefits of Cognitive Training Can Last 10 Years in Older Adults
January 14, 2024 11:35 am | CommentsExercises meant to boost mental sharpness can benefit older adults as many as 10 years after they received the cognitive training, researchers said. A multi-institutional team of researchers reported that older adults who had participated in the mental exercise programs reported less difficulty with everyday tasks of living than were those who had not participated, even after 10 years had passed.
Caffeine Has Positive Effect on Memory
January 13, 2024 11:43 am | CommentsWhether it's a mug full of fresh-brewed coffee, a cup of hot tea, or a can of soda, consuming caffeine is the energy boost of choice for millions who want to wake up or stay up. Now, researchers at Johns Hopkins University have found another use for the popular stimulant: memory enhancer.
Complementary Medicine in Wide Use to Treat Children with Autism, Developmental Delay
January 13, 2024 11:14 am | CommentsIn a study of the range of treatments being employed for young children with autism and other developmental delays, UC Davis MIND Institute researchers have found that families often use complementary and alternative medicine (CAM) treatments and that the most frequent users of both conventional and complementary approaches are those with higher levels of parental education and income.
Key Survival Protein Found in Many Cancers
January 8, 2024 1:00 pm | CommentsResearchers have discovered a promising strategy for treating cancers that are caused by one of the most common cancer-causing changes in cells.
New Targets Found for Huntington’s, Parkinson’s
January 8, 2024 12:11 pm | CommentsResearchers have discovered a possible new target for treating movement disorders such as Huntington’s disease and Parkinson’s disease.
Nicotine Exploits COPI to Foster Addiction
December 30, 2023 12:00 pm | CommentsA study in The Journal of General Physiology helps explain how nicotine exploits the body's cellular machinery to promote addiction. The findings could lead to new therapies to help people quit smoking. According to the Center for Disease Control and Prevention, tobacco accounts for the greatest number of preventable deaths worldwide by any single agent.
Brain Coverings May Take Brunt of Concussion Impact
December 9, 2023 12:32 pm | CommentsThere is more than meets the eye following even a mild traumatic brain injury. While the brain may appear to be intact, new findings report that the brain’s protective coverings may feel the brunt of the impact.
