Many Americans unaware high blood pressure usually has no noticeable symptoms

High blood pressure typically has no signs or symptoms, according to the CDC. Few U.S. adults can correctly identify what blood pressure reading is considered high (130/80 mmHg). Despite prevalence, many people mistakenly believe high blood pressure always has noticeable symptoms or can be identified by feeling calm and relaxed.

Fundamentals and challenges for indirect and direct photocatalytic conversion of plastic wastes into valuable fuels

Researchers explore strategies for converting plastics into valuable chemicals through photocatalysis, highlighting indirect conversions of PET, PLA, and PE, as well as direct conversions of PE, PLA, and PVC. The review also discusses challenges and future outlooks for this clean energy source.
