Early interventions help nonspeaking autistic children achieve speech gains

Rss Feed - Thu, 01/22/2026 - 21:39
After receiving evidence-based early interventions, roughly two-thirds of non-speaking kids with autism speak single words, and approximately half develop more complex language, according to a new study led by researchers at Drexel University's A.J. Drexel Autism Institute.

Exercise variety, not just volume, is tied to longer life

Rss Feed - Thu, 01/22/2026 - 21:36
Researchers analysed nearly three decades of data from more than 111,000 adults to examine whether the variety of physical activities people perform is linked to long-term survival. They found that engaging in a broader range of activity types was associated with lower all-cause mortality, independent of total exercise volume.

Targeted uterine mRNA treatment boosts fertility outcomes in mice

Rss Feed - Thu, 01/22/2026 - 21:35
Researchers from the Wilmer Eye Institute, Johns Hopkins Medicine Center for Nanomedicine - which designs nanotechnology-based platforms for clinical translation across specialties - developed a strategy for delivering therapeutic messenger RNA (mRNA) to the inner lining of the uterus (endometrium) in mice via modified lipid nanoparticles (LNPs), which are small capsules made of fatty molecules.

Menopausal hormone therapy linked to greater weight loss with tirzepatide

Rss Feed - Thu, 01/22/2026 - 21:29
A new study led by Mayo Clinic found that postmenopausal women receiving menopausal hormone therapy lost 35% more weight while taking tirzepatide, a Food and Drug Administration-approved drug for the treatment of overweight and obesity.

When you eat matters: early time-restricted eating improves metabolic health

Rss Feed - Thu, 01/22/2026 - 20:39
Time-restricted eating improves several metabolic outcomes compared with usual diets, with benefits observed for body weight, adiposity, blood pressure, insulin, glucose, and triglycerides. Early eating windows consistently outperform late eating, while the optimal duration of food intake remains uncertain.

Brain cell precursors show constant myelin-making drive

Rss Feed - Thu, 01/22/2026 - 14:40
In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells - one of the few brain cell types that continue to be produced in the adult brain - undergo differentiation widely and at a constant pace, rather than "as needed" in response to injury or advancing age.

Brain complexity declines in Alzheimer's disease

Rss Feed - Thu, 01/22/2026 - 14:33
As individuals with Alzheimer's disease (AD) move from the mild cognitive impairment stage to moderate and severe dementia, complex awareness deteriorates although lower-level sensory awareness is relatively maintained.

Pre-surgical medication use grows for pancreatic, gynecologic, and abdominal lining cancers

Rss Feed - Thu, 01/22/2026 - 14:25
The second annual report from the National Cancer Database (NCDB) of the American College of Surgeons (ACS) documents a substantial rise in medication treatments, such as chemotherapy, immunotherapy, and hormone therapy, used before surgery to treat many cancers, often allowing less invasive surgery and helping clinicians assess how a patient's cancer responds to medication to guide the most effective treatment options.

Moffitt researchers develop a new way to predict how cancer cells evolve

Rss Feed - Thu, 01/22/2026 - 14:18
Researchers at Moffitt Cancer Center have developed a new way to predict how cancer cells evolve by gaining and losing whole chromosomes, changes that help tumors grow, adapt and resist treatment.

FIU's personalized cancer treatment shows promise

Rss Feed - Thu, 01/22/2026 - 14:15
Researchers at FIU are advancing a personalized approach to cancer treatment that is showing increasingly promising results for patients with hard-to-treat disease, supported by new philanthropic investment that is helping expand the science behind the work.

Discovery explains why people with IBD have higher risk of colorectal cancer

Rss Feed - Thu, 01/22/2026 - 14:02
A chain of immune reactions in the gut—driven by a key signaling protein and a surge of white blood cells from the bone marrow—may help explain why people with inflammatory bowel disease (IBD) have a higher risk of colorectal cancer, according to a preclinical study by Weill Cornell Medicine investigators.

Facial wound secrets revealed for scarless repair

Rss Feed - Thu, 01/22/2026 - 13:54
Tweaking a pattern of wound healing established millions of years ago may enable scar-free injury repair after surgery or trauma, Stanford Medicine researchers have found.

Alterations in liver metabolism experienced by individuals with Down syndrome

Rss Feed - Thu, 01/22/2026 - 13:42
Researchers at the University of Colorado Anschutz Linda Crnic Institute for Down Syndrome (Crnic Institute) have uncovered compelling evidence that individuals with Down syndrome experience significant alterations in liver metabolism, including elevated levels of bile acids in the bloodstream and other biomarkers of liver dysfunction.
