Next-generation wireless technology may leverage the human body for energy

While you may be just starting to reap the advantages of 5G wireless technology, researchers throughout the world are already working hard on the future: 6G. One of the most promising breakthroughs in 6G telecommunications is the possibility of Visible Light Communication (VLC), which is like a wireless version of fiberoptics, using flashes of light to transmit information. Now, a team has...

Antibiotic residues in water a threat to human health

Antibiotic residues in wastewater and wastewater treatment plants in the regions around China and India risk contributing to antibiotic resistance, and the drinking water may pose a threat to human health, according to a comprehensive analysis.

Specific outdoor air pollutants linked to asthma attacks in urban children

Moderate levels of two outdoor air pollutants, ozone and fine particulate matter, are associated with non-viral asthma attacks in children and adolescents who live in low-income urban areas. The study also identifies associations between exposure to the two pollutants and molecular changes in the children's airways during non-viral asthma attacks, suggesting potential mechanisms for those attacks....
