A large study found that people who moved from smoking cigarettes to using electronic cigarettes had higher lung cancer risk than people who quit smoking entirely. The results suggest vaping may not eliminate cancer risk for former smokers even if it reduces exposure to some cigarette toxins.
8:00 PMNatureMeasurements from the Keck Observatory show that some giant exoplanets spin faster than far more massive brown dwarfs in other systems. The pattern breaks the simple expectation that rotation scales cleanly with mass and points to formation physics as the driver.
8:57 AMScienceDailyA four-year study found that older adults who kept practicing a musical instrument maintained memory performance and showed less age-related brain shrinkage than peers who stopped. The effects were strongest in brain areas linked to memory and learning.
8:24 AMScienceDailySummary
A large study found that people who moved from smoking cigarettes to using electronic cigarettes had higher lung cancer risk than people who quit smoking entirely. The results suggest vaping may not eliminate cancer risk for former smokers even if it reduces exposure to some cigarette toxins.
Why it matters
If vaping is less protective than quitting, public health messaging and regulation will shift toward complete nicotine cessation rather than substitution.
Summary
Measurements from the Keck Observatory show that some giant exoplanets spin faster than far more massive brown dwarfs in other systems. The pattern breaks the simple expectation that rotation scales cleanly with mass and points to formation physics as the driver.
Why it matters
Spin rates can become a practical test of planet formation models, not just a descriptive property of distant worlds.
Summary
A four-year study found that older adults who kept practicing a musical instrument maintained memory performance and showed less age-related brain shrinkage than peers who stopped. The effects were strongest in brain areas linked to memory and learning.
Why it matters
It points to a practical, low-risk way to slow cognitive decline by pairing late-life learning with long-term practice.
