Research sheds light on migration, lifestyle, health and social status in the medieval metropolis Ypers‎

Researchers from the Vrije Universiteit Brussel (VUB) are playing a key role in the summer exhibition wONDERLAND at the Yper Museum. Thanks to interdisciplinary research on more than 1,000 excavated skeletons, they have succeeded in giving the anonymous medieval city dweller a face and a voice once again after centuries.

Smarter, greener ways to protect fragile cultural heritage‎

Museums, libraries, archives and heritage organizations face a difficult problem: Many of the objects they preserve are made from materials that naturally deteriorate.

Wound odors may unlock better traps for flesh-eating New World screwworm‎

Jessica Metcalf's work stinks. Literally. But the Colorado State University professor's research may be key to protecting livestock and wildlife from a flesh-eating parasite.

Long-lived ytterbium states could sharpen quantum computing and atomic clocks‎

Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable states and, if so, for how long. The measured long-lived states may find applications in quantum computers and atomic clocks.

Study explores the hedging capability of cryptocurrencies in turbulent markets‎

The rapid growth of sustainable finance in recent years has fueled interest in green investment, ranging from green bonds and environmental, social and governance (ESG) funds to energy-efficient cryptocurrencies. While these assets are often grouped under the broader umbrella of green finance, their interaction during periods of market stress remains largely unexplored.

Can a robot tutor give too much help? Why timing matters‎

A learner stands in a room with a bottle, a cup and a book. The task is to figure out, step by step, where each object belongs in the room. Under the table? Or perhaps on the chair? A humanoid robot gives the instructions—but in Swahili, a language the learner does not know. To solve the puzzle, the learner must gradually decipher what the robot is saying.

Scientists turn modern biobanks into a new window on human evolution‎

For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations and ancient DNA. Building on these approaches, researchers are increasingly using large population biobanks to investigate how natural selection continues to shape the genomes of living populations.

Gold-catalyzed chemical reaction advances next-generation anticancer prodrugs‎

Anticancer prodrugs have attracted significant attention from the medical and scientific communities in recent years because of their potential to improve treatment precision while reducing side effects. These drugs are engineered to remain inactive until they are activated at specific sites or under particular physiological conditions within the body, at which point they release their therapeutic effect.

New methods for removing harmful nitrates from drinking water identified‎

Nitrate contamination of drinking water poses a major health concern, particularly in agricultural communities where fertilizers, livestock manure and septic systems can leach nitrates into groundwater. Many rural households rely on private water wells, which may not be routinely tested, leading some to consume contaminated water without realizing it.

Quantum dots reveal hidden light waves on metal surfaces‎

Photographs can reveal things that are otherwise impossible for the naked eye to see, be they distant galaxies or microscopic cells. Researchers at Osaka Metropolitan University have developed a practical and versatile imaging technique that makes another usually invisible phenomenon visible: surface plasmon polaritons (SPPs), light waves that travel along metal surfaces.
