Scientists at The Australian National University (ANU) have designed a new nano material that can reflect or transmit light on demand with temperature control, opening the door to technology that protects astronauts in space from harmful radiation. Dr Mohsen Rahmani from ANU said the material was so thin that hundreds of layers could fit on the tip of a needle and could be applied to any surface, including spacesuits.

“Our invention has a lot of potential applications, such as protecting astronauts or satellites with an ultra-thin film that can be adjusted to reflect various dangerous ultraviolet or infrared radiation in different environments,” said Dr Rahmani, an A...

•Plasma TMAO levels are elevated in type 2 diabetic patients
•Levels of the TMAO-producing enzyme FMO3 in adipose tissue correlate with obesity
•Pharmacologic and genetic inhibition of Fmo3 stimulates white adipose tissue beiging
•Inhibition of Fmo3 promotes resistance to obesity

Cleveland Clinic researchers showed that blocking a specific intestinal microbial pathway can prevent obesity and insulin resistance, as well as cause fat tissue to become more metabolically active. The team, led by J. Mark Brown, Ph.D...

A green laser controls the quantum state of the probe, which is tuned to the resonant frequency of target nuclear spins. The probe responds to the nuclear spins of the hydrogen atoms and provides a direct measurement via the red light emitted. Credit: David A. Broadway/cqc2t.org

Limitations of conventional NMR spectroscopy overcome. Researchers at the University of Melbourne have demonstrated a way to detect nuclear spins in molecules non-invasively, providing a new tool for biotechnology and materials science...

Researchers have developed the world’s most narrowband diode laser on a chip. This laser represents a breakthrough in the fast-growing field of photonics, and will bring applications like 5G internet and accurate GPS closer. We are slowly reaching the bounds of what is possible with electronics. That is why scientists and the private sector are committed to photonics – a key technology that makes numerous other innovations possible. This involves the deployment of photons (light particles) for transporting and processing data.

For photonic chips to function as efficiently as possible, one has to be able to properly control the light signals...
