Sunlight gives biodiesel byproduct a second life as hydrogen and valuable chemicals‎

Australian researchers and international collaborators have demonstrated a solar-driven approach to convert glycerol, a low-value byproduct of biodiesel production, into hydrogen and higher-value chemicals. Using advanced techniques at the Australian Synchrotron, they revealed how the catalyst changed while it was working.

A highway instead of a racetrack: Strong coupling of light and sound in an optical fiber‎

For the first time, scientists have achieved strong coupling between light and long-lived acoustic vibrations in an optical fiber. Optical fibers are used in both classical telecommunications and quantum communication and could serve not only as connections between computing nodes but also as quantum processors themselves in the future. The results, published in Nature Physics, pave the way for new technologies in quantum signal processing.

First comprehensive Mars soil classification offers framework for exploration and future farming‎

A Ph.D. student at the University of Sydney has produced the first comprehensive classification system and map of Martian soils, creating a new framework that could help scientists compare landscapes across the Red Planet and identify promising locations for future exploration, habitation and food production.

Judging strangers' preferences may actually be easier when they're less like our own‎

Researchers already know that humans have a tendency to use egocentric anchoring—a cognitive bias in which people use their own preferences, beliefs and perspectives as a mental starting point (or anchor) to understand or predict what another person thinks, feels or prefers. This is not necessarily a sign of selfishness or self-importance, but a way for us to better understand others.

Essential oil sprays kill cockroaches on contact but offer little lasting control‎

A German cockroach races across a kitchen floor. Someone grabs a bottle of essential oil spray, soaks the insect and watches it die. The product worked, but a new University of Kentucky study suggests the larger infestation probably did not notice.

Belief in change matters more than political anger when it comes to voting intentions, study suggests‎

With the 2026 midterm elections around the corner, voters may be feeling everything from excitement to fear. But how might anger motivate political activism and, ultimately, influence who turns out to vote?

Climate warming can slow how tree roots feed soil microbes‎

A plant's roots do much of their work out of sight, pulling in water and nutrients and holding the plant in place. That makes it hard to see how plants respond when conditions underground change, and how a warming climate affects them. New Dartmouth-led studies look at the strategies plants use below the surface to adapt and survive.
