Setback in the fight against pediatric HIV

Blocking brain damage triggered by a glioblastoma, an aggressive brain cancer, may slow the growth of the cancer and allow the brain to keep working better for longer, according to a new study led by UCL (University College London) researchers.

All cells in the body contain the same DNA, but different cell types express different genes; skin cells express genes for the skin, liver cells express liver genes, and so on. This coordination is crucial to help cells differentiate into their assigned roles, but a new study by researchers at the University of Chicago shows how cells can randomly "shake up" regions of the genome to express genes normally reserved for other cell types.

Routine testing for a specific lipoprotein known as Lp(a) would be a cost-saving way to significantly reduce the risk of cardiovascular disease and save lives, according to an international research taskforce led by Monash University.

A specialized chatbot named Noora is helping individuals with autism spectrum disorder practice their social skills.

The Institute of Neuroscience, Chinese Academy of Sciences, reports that human stem cell-derived A10-like midbrain dopaminergic neurons integrate into mouse mesocorticolimbic circuits and suppress anxiety and depression behaviors upon activation.

University of Utah researchers found strong evidence that exposure to industrial pollution during pregnancy can shape a grandchild's neurodevelopment. A child has a higher risk of an intellectual disability if their grandmothers lived near industrial facilities while pregnant with a parent, especially the mother. Higher density of industrial facilities corresponded to higher risk for the grandchild.

In Guatemalan communities, a recent visit to a health clinic or hospital—not antibiotic use—is the strongest predictor of carrying bacteria resistant to critical antibiotics, according to a new study led by Washington State University.

Effectively managing chronic conditions like diabetes and hypertension can greatly improve quality of life, reduce complications and extend longevity for older adults. However, when treatment becomes overly aggressive, it can do more harm than good.

Having lived with an ALS diagnosis since 2018, Kate Nycz can tell you firsthand what it's like to slowly lose motor function for basic tasks. "My arm can get to maybe 90 degrees, but then it fatigues and falls," the 39-year-old said. "To eat or do a repetitive motion with my right hand, which was my dominant hand, is difficult. I've mainly become left-handed."

Monash University researchers have identified a molecular biomarker in triple negative breast cancer (TNBC) tumors which could inform when beta blockers can play a role in "switching off" tumor progression.

Analysis of lipids—fat molecules that perform many essential functions in the body—in the blood found there was a noticeable loss of unsaturated fats, such as those that contain omega fatty acids, in the blood of women with Alzheimer's disease compared to healthy women.

August is National Minority Donor Awareness Month. It's a time of celebrating organ donation and educating people about transplantation by encouraging donor registration and promoting healthy living.

People thinking about starting a business or retiring early—before they're old enough for Medicare—may want to wait until November, when they can see just how much their Affordable Care Act health insurance will cost next year. Sharp increases are expected.

From 2023 to 2024, coverage with one or more doses of the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) and the quadrivalent meningococcal conjugate vaccine (MenACWY) increased, while human papillomavirus (HPV) vaccination coverage remained stable, according to research published in the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.

U.S. adults aged 65 and older with high blood pressure, heart failure or stroke had significant declines in cardiovascular health, according to new research published in the Journal of the American Heart Association.

UCSF scientists caught cancer cells in the act of breaking into fat cells and releasing their fat. The energy heist seems to be critical for the growth of deadly breast cancer. The study appears in Nature Communications.

Researchers from the University of California San Diego Sanford Stem Cell Institute have developed a novel method to stimulate and mature human brain organoids using graphene, a one-atom-thick sheet of carbon.

Epidemiological studies have revealed a strong correlation between red meat consumption and the development of inflammatory bowel disease. In a new study published in Molecular Nutrition and Food Research that was conducted in mice, red meat consumption caused an imbalance of bacteria in the intestinal microbiota.
