Silver nanoparticles show promise in fighting antibiotic-resistant bacteria

In a new study, scientists with the University of Florida found that a combination of silver nanoparticles and antibiotics was effective against antibiotic-resistant bacteria. The researchers hope to turn this discovery into viable treatment for some types of antibiotic-resistant infections. Antibiotic-resistant infections kill more than a million people globally each…

Ultra-processed foods may be linked to increased risk of cancer

Higher consumption of ultra-processed foods may be linked to an increased risk of developing and dying from cancer, an Imperial College London-led observational study suggests.
