Alcohol’s hidden toll: a leading cause of everyday violence
Alcohol plays a central yet under-recognised role in everyday violence across French society – within families, public spaces, and intimate relationships. A quarter of perpetrators in non-fatal intentional violence cases in Béziers were under the influence of alcohol or drugs…
Blocking one protein extended mouse lifespan by 25%
Scientists have developed a promising anti-aging drug that has been shown to extend lifespan by up to 25% in lab tests. This breakthrough targets the molecular processes associated with aging, suggesting potential for significantly delaying age-related diseases and enhancing longevity.…
DNA sugar shows promise as a simple, drug-free way to regrow hair
Researchers from COMSATS University in Pakistan and the University of Sheffield accidentally discovered that a naturally occurring DNA sugar, 2-deoxy-D-ribose, can restart hair growth in mice with testosterone-linked baldness. When the sugar was mixed into a biodegradable gel and rubbed…
WHO: adults need 150 to 300 minutes of moderate exercise per week
The WHO recommends adults engage in at least 150–300 minutes of moderate-intensity exercise or 75–150 minutes of vigorous-intensity physical activity weekly. Children and adolescents should accumulate 60 minutes per day. Regular exercise helps reduce the risk of cardiovascular disease, diabetes,…
For older adults, very long daily fasts were linked to higher heart death risk
Time restricted eating means limiting food to a set daily window, for example eating within 8 to 12 hours and fasting the rest of the day. In a large US study of older adults, longer fasting windows were linked to…
Scientists identify the “glue” protein KIBRA that keeps long-term memories from fading away
Scientists identify KIBRA, a protein acting as memory glue to stabilize synapses. This breakthrough explains how long-term memories survive for decades.
A sugar found in the body may help hair regrow without drugs
A study in mice suggests that the simple sugar 2-deoxy-D-ribose, which the body already makes as part of DNA, can restart hair growth that was shut down by testosterone. Its effect on hair length, thickness, and density matched the result…
Resting 2-3 minutes between sets maximises muscle growth, while 3-5 minutes gives the best strength gains
Lifting weights keeps muscle tissue strong, bones dense and joints stable, which maintains mobility and lowers the risk of falls and fractures as we age. It also improves blood-sugar control, heart health and metabolic rate, while recent studies show it…
