New knee arthritis treatment delivers lasting pain relief without surgery
A promising new treatment for knee arthritis uses tiny, dissolvable particles to block abnormal blood vessels, easing inflammation and pain without joint replacement surgery. In a study of 194 patients, 80% experienced clinically meaningful pain relief lasting at least 12 months.

AI can act exactly like a human, but we still don't think it's conscious
A new study reveals that people draw a surprisingly sharp line between human consciousness and artificial intelligence, even when both behave identically. Researchers found that participants considered even the most responsive AI less conscious than the least responsive human. Yet when asked about "awareness" instead, people judged humans and AI much more similarly.
Scientists discover a surprising paradox in how our cells age
Scientists have discovered that the body's cellular recycling system behaves very differently during aging than previously believed, with higher activity sometimes linked to worse physical health. A small study suggests that even gentle exercise could help restore more youthful cellular recycling patterns in older adults.
This tiny jurassic predator helped pave the way for the human brain
A 165-million-year-old fossil has revealed an extraordinary Jurassic predator that may help explain how mammals developed one of their most important evolutionary advantages. Although only 20 inches long, Megacauda sungei was a heavyweight among early mammal relatives, swimming through ancient waterways and hunting prey with specialized teeth. Its advanced swallowing anatomy reveals an early step toward the ability to safely nurse on milk, a key development in mammalian evolution.
Global brain activity links subcortical degeneration to cortical tau progressively across Braak regions over early Alzheimer's disease stages
Alzheimer's disease (AD) is characterized by early tau pathology in subcortical neuromodulatory nuclei, followed by progressive cortical tau accumulation; however, the mechanisms linking subcortical dysfunction to cortical tau pathology remain unclear. Using multimodal neuroimaging data from the ADNI cohort, we examined how infra-slow ( < 0.1 Hz) global brain (i.e., gBOLD) activity is related to the volume of the nucleus basalis of Meynert (NbM) and cortical tau accumulation in the early stages...

Sleeve Gastrectomy Improves Metabolic Health, Cognition, and Alzheimer's Disease Pathology in 3xTG Mice
Obesity and diabetes are well-established risk factors for Alzheimer's disease (AD), implicating metabolic dysfunction in AD pathogenesis. Sleeve gastrectomy (SG) is among the most effective metabolic interventions available, yet its impact on AD progression remains poorly understood. We hypothesized that SG performed early in life would improve metabolic health, attenuate AD pathology, and preserve cognition in a transgenic AD mouse model. Five-week-old female 3xTg-AD mice were preconditioned...
