Negative refraction of light using atoms instead of metamaterials

Scientists have demonstrated that negative refraction can be achieved using atomic arrays — without the need for artificially manufactured metamaterials. Scientists have long sought to control light in ways that appear to defy the laws of Nature. Negative refraction — a phenomenon where light bends in the opposite direction to its usual behavior — has

Worm surface chemistry reveals secrets to their development and survival

A new study has revealed the clearest-ever picture of the surface chemistry of worm species that provides groundbreaking insights into how animals interact with their environment and each other. These discoveries could pave the way for strategies to deepen our understanding of evolutionary adaptations, refine behavioural research, and ultimately overcome parasitic infections.

Jacket uses AI to keep you comfortable

Electronic textiles, such as heating pads and electric blankets, can keep the wearer warm and help ease aches and pains. However, prolonged use of these devices could possibly cause heat-related illnesses, including hyperthermia or burns. Recently, a group of researchers designed and tested a ‘smart’ jacket equipped with environmental sensors, heat-generating and color-changing yarns, and

Tidal energy measurements help scientists understand Titan’s composition, orbital history

Scientists are studying Saturn’s moon Titan to assess its tidal dissipation rate, the energy lost as it orbits the ringed planet with its massive gravitational force. Understanding tidal dissipation helps scientists infer many other things about Titan, such as the makeup of its inner core and its orbital history.
