Lasers are widely used as high power sources of light operating at a specific frequency. But how does this frequency get selected when a laser is turned on, and how quickly?

Pioneering engineers working with terahertz frequency technology have been researching how individual frequencies are selected when a laser is turned on, and how quickly the selection is made.

The development of specific terahertz equipment has allowed them to investigate this process for the first time. Their results, published in Nature Communications, will underpin the future development of semiconductor lasers, including those used in public and private sector-owned telecommunications systems.

A researcher from the University of Rhode Island’s Graduate School of Oceanography and five other scientists have discovered an active volcanic heat source beneath the Pine Island Glacier in Antarctica.

The discovery and other findings, which are critical to understanding the stability of the West Antarctic Ice Sheet, of which the Pine Island Glacier is a part, are published in the paper, “Evidence of an active volcanic heat source beneath the Pine Island Glacier,” in the latest edition of Nature Communications.

Assistant Professor Brice Loose of Newport, a chemical oceanographer at GSO and the lead author, said the paper is based on research conducted during a major expedition in 2014 to Antarctica led by scientists from the United Kingdom. They worked aboard an icebreaker, the RRS James Clark Ross, from January to March, Antarctica’s summer.

Scientists are using the Japanese art of origami to inspire various technological innovations, including a bulletproof shield and a deep-sea grabber.

The Department of Energy is betting big on a new technology to turn saltwater into freshwater.

In Gwalior, a congested city in the centre of the India, an 8th-Century fort rises with medieval swagger on a plateau in the town’s heart. Gwalior Fort is one of India’s largest forts; but look among the soaring cupola-topped towers, intricate carvings and colourful frescoes and you’ll find a small, 9th-Century temple carved into its solid rock face.

This is ground zero for zero

Chaturbhuj Temple is much like many other ancient temples in India – except that this is ground zero for zero. It’s famous for being the oldest example of zero as a written digit: carved into the temple wall is a 9th-Century inscription that includes the clearly visible number ‘270’.

By studying frogs’ eggs, researchers have measured the rate at which cells kill themselves off for an organism’s greater good

I wish the academy would incentivise scholars to improve society, not chase citations. I want us to reimagine a PhD that is designed not to win kudos within the academic community, but rather aimed at discovering something new that will be useful for practitioners and have real social impact.

Too much research is aimed at insular academic circles rather than the real world. Let’s fix this broken system.
