New scavenger technology allows robots to ‘eat’ metal for energy

When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have a limited supply. Harvesters, such as solar panels, collect energy from their environments. This gets... Continue Reading →

Key nose cells identified as likely COVID-19 virus entry points

The study, published online in the... Continue Reading →

Strongest evidence yet that neutrinos explain how the universe exists

New data throws more support behind the theory that neutrinos are the reason the universe is dominated by matter. The current laws of physics do not explain why matter persists over antimatter -- why the universe is made of 'stuff'.... Continue Reading →
