A massive study tracking nearly 80,000 men over five decades has revealed a striking connection between semen quality and life expectancy. Those with higher motile sperm counts were found to live two to three years longer than those with significantly lower counts. Researchers suggest that poor semen quality may be an early warning sign of […]

Tired of tossing and turning? Strength training could be your best bet for better sleep. A review of studies found that older adults who engaged in muscle-strengthening exercises saw the biggest improvements in sleep quality. While aerobic and combination exercises helped, resistance training stood out as the most effective. Strength Training May Be the Best […]

Everyday products contain unregulated toxic chemicals. For years, the scientific community has assumed that polymers—large molecules—are too big to migrate from products into the human body and therefore pose no health risks. As a result, polymers have largely remained unregulated and are exempt from major toxic substance laws, such as the U.S. Toxic Substances Control […]

A groundbreaking study reveals that taking a higher dose of folic acid in early pregnancy can significantly enhance a child’s verbal and behavioral skills by age six. The research, which analyzed 345 children, found that those whose mothers took folic acid scored higher in language and social abilities compared to those who did not. Encouragingly, […]

Researchers developed a high-solubility pyrene tetraone derivative (PTO-PTS) that enhances AOFB energy density and stability. This monomer enables reversible four-electron storage, achieving 90 Ah/L and maintaining 100% capacity retention after 5,200 cycles. Aqueous organic flow batteries (AOFBs) are a promising technology for integrating renewable energy and enhancing electricity grid storage, thanks to their inherent safety […]
