Shining blue light on gold-graphene nanodots achieves wound healing trifecta

Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, one to clean the wound and one to support recovery.

Ancient algal defenses against UV may have helped plants conquer land

A new study sheds light on how the ancestors of modern land plants survived one of the most challenging aspects of life outside water: exposure to harmful ultraviolet (UV) radiation. By examining a microscopic alga closely related to the earliest land plants, researchers have unc

Age bias discovered in AI

Do responses generated by artificial intelligence systems such as ChatGPT reflect social prejudice? A KAIST research team has quantitatively analyzed and identified age-related stereotypes embedded in the responses of generative artificial intelligence. The study sheds light on t

Light-activated compound kills antibiotic-resistant bacteria by turning its own defense en

Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years. The problem is exacerbated when antibiotics wipe out susceptible bacteria but leave resistant bacteria behind to multiply, further spreading resistance. Ther

Switching spin states in manganese ions with light opens new path for molecular memory

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular materials, which require very low temperatures—ran

Nova V612 Scuti's light curve becomes audio, revealing how stellar shocks evolved

Researchers in the Department of Physics & Astronomy at Texas Tech University recently used audio to represent the spectacular explosion of a star in deep space while also delving into the data to better understand how the phenomenon unfolded.

Synthetic chemical framework can switch magnetic spin states at near ambient temperatures

There is growing demand for smart materials that can change their physical properties in response to various external stimuli such as light, heat, pressure, magnetic fields and electric fields. One such physical property is the magnetic state of material complexes, which depends

Camouflaging snails change color in the rain

How does a stripy tree snail hide from hungry birds? The Hypselostyla camelopardalis from the Philippines and Reinia variegata from Japan have both evolved a form of dynamic camouflage to survive. Their light-colored patterns vanish in the rain, and the shell turns dark brown, si

Nearby 'Super Earth' may be a better candidate for life than previously thought

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf. Just 25 light-years

Galaxy groups hiding in the universe's emptiest places

Imagine standing in the emptiest place the universe has to offer, a stretch of cosmic ocean so vast that light takes tens of millions of years to cross it, and yet still finding company. That is the puzzle behind a new study built on the Calar Alto Void Integral field Treasury su

Webb reveals merger scars in galaxies that stopped forming stars 9 billion years ago

Research has shed new light on why some distant galaxies suddenly stop forming stars. An international team led by astronomers at the University of Nottingham has used the James Webb Space Telescope to study a large sample of recently "quenched" galaxies in the distant universe,
