A global report into the chocolate industry has found that while some companies are improving their sustainability practices, many retailers are still failing to ensure transparent and accountable cocoa supply chains that would protect cocoa farming communities.

The Swedish government recently announced it was moving from the classroom use of digital devices back to physical books. It cited concerns over declining test scores and increasing screen time.

Until now, studying the genetic processes in cells required destroying them—making it impossible to observe these processes over extended periods of time. A team from the Technical University of Munich (TUM) and Helmholtz Munich has developed a new method to repeatedly obtain up-to-date genetic information from living cells. In the future, this will enable better monitoring of stem cells for therapies or the effects of drugs within cells.

A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel. Even more impressive, it could replace costly titanium parts used in today’s hydrogen systems.
