Teachers in Johannesburg's public secondary schools are facing an unseen challenge: chalk dust. A recent study shed light on how teachers handle this everyday hazard. Most teachers, around 95%, have never had any training on the risks of chalk dust. This lack of knowledge leads to a worrying trend:
Lithium-sulfur batteries are a big deal. They can store a lot of energy, but they have a problem. The stuff inside them, called lithium polysulfides, moves around too much. This makes the batteries wear out faster. Scientists are trying to fix this by making better catalysts. These are like helpers
Kyrgyzstan is gearing up for a snap parliamentary election, with President Sadyr Japarov's allies poised to secure a significant victory.

Scientists are now looking at the big picture of health. They are not just focusing on genes. Instead, they are studying everything around us that might cause disease. This new area is called exposomics. It is like a map of all the things we come into contact with in our lives. Most diseases are no
Neuroscience is stepping away from old ideas that label brain differences as problems. Instead, it's looking at each person's brain as a unique network. This shift is called precision neurodiversity. It's about seeing how our brains are wired differently and how that affects how we think and behave.

Asteroids might have been like cosmic delivery trucks, bringing essential supplies for life to Earth. Scientists recently found tryptophan, an important amino acid, in samples from asteroid Bennu. This discovery adds to the growing list of life's building blocks found in space rocks. Bennu is a sma
