Less than a quarter of us hit WHO activity targets, but a new UCL study suggests the trick may be matching workouts to our personalities: extroverts thrive in high-energy group sports, neurotics prefer private bursts with breaks, and everyone sees stress levels drop when they find exercise they enjoy.

A new UCL study reveals that aligning workouts with personality boosts fitness and slashes stress—extroverts thrive on HIIT, neurotics favor short, private bursts, and everyone benefits when enjoyment leads the way.

UCLA scientists mined millions of electronic health records and uncovered four distinct “roadways” that funnel people toward Alzheimer’s—ranging from mental-health struggles to vascular troubles. Following these breadcrumb trails proved far better at predicting who will develop dementia than single risk factors. The findings hint that spotting—and halting—specific sequences early could rewrite how we prevent the disease.

Patients who undergo tummy tuck surgery may be in for more than just cosmetic changes — a new study shows they often keep losing weight for years after the procedure. Researchers followed 188 patients and found consistent weight reduction up to five years later, especially in those with higher initial BMIs. Interestingly, lifestyle improvements, such as better diet and exercise habits, may play a key role in this surprising long-term effect. This could mean tummy tucks aren't just sculpting bodies — they may be reshaping lives.

When you're mentally exhausted, your brain might be doing more behind the scenes than you think. In a new study using functional MRI, researchers uncovered two key brain regions that activate when people feel cognitively fatigued—regions that appear to weigh the cost of continuing mental effort versus giving up. Surprisingly, participants needed high financial incentives to push through challenging memory tasks, hinting that motivation can override mental fatigue. These insights may pave the way to treating brain fog in disorders like PTSD and depression using brain imaging and behavior-based therapies.
