How Much Exercise Does Your Heart Actually Need?
New observational research published in the British Journal of Sports Medicine links 10 weekly hours of exercise to a 30%-plus drop in cardiovascular risk, well above the 150-minute WHO guideline.
Women Face Greater Dementia Risk From Same Factors as Men
New research published in Biology of Sex Differences finds that modifiable dementia risk factors affect women's cognition more severely than men's, even when prevalence is similar — pointing toward sex-tailored prevention strategies.
Why Scientists Still Can't Measure Big G Precisely
Despite centuries of effort and modern precision instruments, Newton's gravitational constant G is known to only 3 significant figures. NIST and BIPM are running a rare cross-laboratory replication to find out why high-precision experiments keep disagreeing.
NASA Psyche Spacecraft Completes Mars Gravity Assist
The Psyche spacecraft completed a Mars gravity assist on May 15, 2026, swinging past the planet at over 12,000 mph to redirect its trajectory toward metallic asteroid 16 Psyche without burning extra propellant.
Scientific Agent Skills: 135 Open-Source AI Research Tools
K-Dense has renamed its open-source repository to Scientific Agent Skills and launched K-Dense BYOK, a desktop co-scientist supporting 40+ models and local-to-cloud scaling via Modal.
Why Almost Everyone Is Right-Handed
New Bayesian modeling across 2,025 primates shows that walking upright and encephalization, not culture or tool use alone, explain why ~90% of humans favor their right hand.
Silicone Pollutants From Car Exhaust Found Globally
Researchers measured methylsiloxanes in atmospheric samples globally, tracing the source to vehicle exhaust and raising questions about human inhalation exposure and cloud formation interference.
