Techniques developed by astronomers could help in the fight against breast and skin cancer. A large part of astronomy depends on the detection and analysis of light. For example, scientists study the light scattered, absorbed and re-emitted in clouds of gas and dust, obtaining information on their interior.

Despite the vast differences in scale, the processes that light undergoes when travelling through the human body are very similar to those seen in space. And when things go wrong – when tissue becomes cancerous – that change should show up.

In the UK, nearly 60,000 women are diagnosed with breast cancer each year, and 12,000 die...

Researchers from the University of Georgia are giving new meaning to the phrase “turning rust into gold”—and making the use of gold in research settings and industrial applications far more affordable. They combine small amounts of gold nanoparticles with magnetic rust nanoparticles to create a hybrid nanostructure that retains both the properties of gold and rust. “Medieval alchemists tried to create gold from other metals,” she said...
