    Helping with grandkids may slow cognitive decline
    29/01/26 09:06:44
    Helping care for grandchildren may offer an unexpected boost to brain health later in life. Researchers found that grandparents who provided childcare scored higher on memory and verbal skills than those who did not. The effect did not depend on how often they helped or the type of care they provided. Being involved as a caregiver itself appeared to matter most.

    Long-term alcohol use linked to a sharp rise in rectal cancer
    29/01/26 07:09:04
    Drinking heavily over many years is linked to a higher risk of colorectal cancer, especially rectal cancer, according to new research tracking U.S. adults for two decades. People who drank heavily throughout adulthood faced sharply higher risks than light drinkers. Former drinkers did not show increased cancer risk and had fewer precancerous tumors. The results suggest that quitting alcohol may help lower long-term cancer risk.

    A breakthrough that turns exhaust CO2 into useful materials
    29/01/26 06:28:18
    Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring purified CO2. It converts the captured gas into formic acid, which is used in energy and manufacturing. The system even functions at CO2 levels found in normal air.

    Study raises red flags over long-term effectiveness of popular weight loss drugs like Ozempic
    28/01/26 13:53:59
    Ozempic, Mounjaro, and Zepbound can drive impressive weight loss, but stopping them is often followed by rapid weight regain. Researchers found that people regain weight faster after quitting these drugs than after diet and exercise alone. Improvements in heart health and diabetes risk also tend to reverse within a few years. The results suggest long-term success may require more than medication alone.

    Dark stars could solve three major mysteries of the early universe
    28/01/26 16:05:20
    JWST has revealed a strange early universe filled with ultra-bright “blue monster” galaxies, mysterious “little red dots,” and black holes that seem far too massive for their age. A new study proposes that dark stars—hypothetical stars powered by dark matter—could tie all these surprises together. These exotic objects may have grown huge very quickly, lighting up the early cosmos and planting the seeds of supermassive black holes.
