Exercise may not help hip arthritis as much as patients expect
A major review found that exercise produces only small average improvements in hip osteoarthritis pain and physical function. It may still help some people, but researchers warn that current evidence is too limited to know which exercises work best.
A single sauna session sends immune cells surging
A single 30-minute sauna session may briefly put the immune system on higher alert. Finnish researchers found that sauna heat, paired with a short cold shower, increased every type of white blood cell circulating in the bloodstream, including key infection fighters such as neutrophils and lymphocytes.
Your dreams aren’t random. Your brain is rewriting reality
Dreams are not random mental noise. A large study of more than 3,700 dream and waking reports found that what we experience during sleep is shaped by both our personalities and the world around us. Rather than simply replaying daily events, the dreaming brain mixes memories, emotions, imagined possibilities, and familiar settings into vivid new scenarios.
Scientists reveal what sparkling water really does to your teeth
Unsweetened sparkling water may offer a tooth-friendlier alternative to sugary soda, according to a small preliminary study tracking how different drinks change mouth acidity. Soda caused the strongest and longest drop in salivary pH, while sparkling water produced only a temporary decline before saliva restored normal conditions. Importantly, acidity remained above the level associated with enamel damage.

Pharmacological potential of wogonin in rotenone induced mice model of Parkinson's disease via targeting GSK-3beta
Wogonin, a naturally occurring flavonoid derived from Scutellaria species and widely used in traditional East Asian medicine for its anti-inflammatory and antioxidant effects. Although wogonin has demonstrated efficacy against oxidative stress and inflammation, its mechanistic role in Parkinson's disease (PD) remains incompletely understood. The present study investigated the neuroprotective potential of wogonin in a rotenone-induced mice model of PD, with particular emphasis on modulation of...
