Companies struggle to realize circular ambitions, says researcher‎

The research, conducted by Wierikx at the Department of Industrial Engineering & Innovation Sciences, is based on more than 3,000 organizational assessments. The results reveal a consistent pattern: companies are relatively strong in setting circular ambitions, but face major challenges in scaling initiatives and embedding circularity into day-to-day business operations.

Not just a fun hobby: Board games can help build connections and reduce stress‎

Researchers at the University of Plymouth recently confirmed what board game fans and role-playing game (RPG) enthusiasts have known for decades: that tabletop games "enhance well-being, foster inclusion, and support learning, with strong evidence that games improve engagement."

Gold-coated optical fiber rapidly gathers microscopic targets for faster, more sensitive detection‎

Osaka Metropolitan University researchers have developed a light-driven technique that quickly amasses thousands of bacteria into a single spot, boosting detection speed and sensitivity. Their approach paves the way for earlier diagnosis of disease. The study is published in Communications Physics.

Study shows how sunspot activity speeds up reentries‎

It's getting crowded up there. Over the past few years, the advent of SpaceX's Starlink and other players in the mega-satellite constellation game are adding an exponential load of satellites and orbital debris to the low Earth orbit environment. But all that goes up, must eventually come down. Now, a new study looks at solar activity over time as a predictor for how reentries trend.

Mathematicians solve decades-old mystery about the hidden order in high-dimensional randomness‎

Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel prize winner—that first posed the problem didn't believe it would ever be solved. The solution provides insight into high-dimensional random structures that could potentially impact data science, machine learning and optimization.

The impact of microplastics on ocean carbon uptake‎

Marine microplastics affect algae's ability to grow and photosynthesize. Researchers have now calculated what impact this has on the greenhouse effect and the ocean's ability to absorb carbon dioxide.

Hydrous mantle minerals reveal possible source of seismic anisotropy in stagnant slabs‎

Seismic waves traveling through Earth's interior often propagate at different speeds depending on their direction, a phenomenon known as seismic anisotropy. Such anisotropy is commonly detected beneath subduction zones, particularly near stagnant slabs in the mantle transition zone and uppermost lower mantle. However, the physical origin of these signals has remained uncertain.

'Patchwork families' existed more than 5,000 years ago, Neolithic DNA reveals‎

Children from previous relationships growing up as siblings in a new family, couples adopting or fostering children: So-called patchwork families are a widespread way of life today. It is considered modern, but is in fact ancient, according to a recent analysis of human genetic material from the Neolithic period.
