Pearls have long been favored as objects of beauty. Now, Purdue University innovators are using the gem to provide potential new opportunities for spectral information processing that can be applied to spectroscopy in biomedical and military applications.

The Purdue team demonstrated light transport-assisted information processing by creating a pearl spectrometer.

Spectrometers probe interactions of matter and light as a function of the electromagnetic spectrum and are commonly used in biomedical and military applications. For example, they have been used for diagnostics of various types of cancer and for military gas sensing.

By studying the site of a spectacular stellar explosion seen in April 2020, a Chalmers-led team of scientists have used four European radio telescopes to confirm that astronomy’s most exciting puzzle is about to be solved. Fast radio bursts, unpredictable millisecond-long radio signals seen at huge distances across the universe, are generated by extreme stars called magnetars — and are astonishingly diverse in brightness.

For over a decade, the phenomenon known as fast radio bursts has excited and...

A novel outpatient procedure offers lasting pain relief for patients suffering from moderate to severe arthritis in their hip and shoulder joints, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA). Researchers said the procedure could help reduce reliance on addictive opiates.

People with moderate to severe pain related to osteoarthritis face limited treatment options. Common approaches like injections of anesthetic and corticosteroids into the affected joints grow less effective as the arthritis progresses and worsens.

“Usually, over time patients become less responsive to these injections,” said Felix M. Gonzalez, M.D., from the Radiology Department at Emory University School of Medicine in Atlanta, Georgia...

Rechargeable lithium-ion batteries (LIBs) are considered the best hope for next-generation battery technology, thanks to their long-life cycle, high specific power and energy density. However, they have not met the ever-increasing demands of emerging technologies such as electric vehicles. Li-Se battery technology is increasingly considered a real alternative to LIBs because of its high theoretical volume capacity and much higher conductivity.

In the first study of its kind, published by the Nature Communications journal, engineers from Surrey’s Advanced Technology Institute (ATI), in collaboration with the team at University Technology of Sydney det...
