A new study from China, published in the science journal Andrology, reveals a concerning link between prolonged computer use for leisure and the increased risk of erectile dysfunction. Researchers found that for every 1.2 hours per day spent on a computer, men raised their chances of experiencing erectile dysfunction by 3.57 times. While moderate physical activity could potentially help alleviate this issue, further research is needed to confirm these findings and their implications for men’s health.

Scientists have made strides in using CRISPR gene editing to potentially eliminate HIV by cutting out “bad” DNA from infected cells, with hopes of developing a cure strategy, as reported by the BBC. While early findings show promise in targeting dormant HIV in cell samples, challenges remain in proving the effectiveness and safety of this approach in treating the virus on a larger scale in animals and humans.

After nearly a decade of endorsing Weight Watchers, Oprah Winfrey has shifted gears, questioning the CEO of her former sponsor, now known as WW International, during an ABC special.

Individuals with post-traumatic stress disorder often experience prolonged fear and anxiety following traumatic events. Researchers from the University of California San Diego delved into the neural mechanisms sustaining this fear, identifying a brain switch triggering “Fear generalization.” By investigating lab mice and individuals with PTSD, they pinpointed a neurotransmitter switch in the brainstem responsible for this persistence of fear. Their study proposes potential interventions, offering hope for managing PTSD and related disorders effectively.

78-year-old “Polio Paul” Alexander, who lived in an iron lung since the 1950s after surviving polio, passed away.
