Natural hydrogel can make personal hygiene products greener‎

A natural, superabsorbent material developed at the University of Waterloo could dramatically reduce the environmental impact of personal hygiene products like diapers, menstrual pads and tampons.

Porous copper nanosheets boost energy output in wearable nanogenerators‎

In recent years, two-dimensional (2D) single-crystalline metal nanosheets have emerged as a promising next-generation platform for self-powered electronics. However, their potential for triboelectric nanogenerators (TENGs)—a promising energy-harvesting technology—remains largely untapped, mainly due to their low current output and limited durability.

Tree bark microbes also clean the air by removing greenhouse and toxic gases‎

Australian researchers have discovered a hidden climate superpower of trees. Their bark harbors trillions of microbes that help scrub the air of greenhouse and toxic gases.

Replication efforts suggest 'smoking gun' evidence isn't enough to prove quantum computing claims‎

A group of scientists, including Sergey Frolov, professor of physics at the University of Pittsburgh, and co-authors from Minnesota and Grenoble have undertaken several replication studies centered around topological effects in nanoscale superconducting or semiconducting devices. This field is important because it can bring about topological quantum computing, a hypothetical way of storing and manipulating quantum information while protecting it against errors.

Unexpected oscillation states in magnetic vortices could enable coupling across different physical systems‎

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states—so-called Floquet states—in tiny magnetic vortices. Unlike earlier experiments, which required energy-intensive laser pulses to create such states, the team in Dresden discovered that a subtle excitation with magnetic waves is sufficient.

Some dogs can learn new words by eavesdropping on their owners‎

"Honey, will you take Luna to the P-A-R-K?" Both parents and dog owners know that some words should not be spoken, but only spelled, to prevent small ears from eavesdropping on the conversation. At the age of 1.5 years, toddlers can already learn new words by overhearing other people. Now, a study published in Science reveals that a special group of dogs are also able to learn names for objects by overhearing their owners' interactions.

Other people's backgrounds shape their social position, but I worked hard for mine: The paradox in how we view status‎

The concept of "hard work v privilege," and what either one says about someone's social status, is an important one.

How did these strange, ancient organisms turn into such remarkable fossils?‎

In Earth's fossil record, soft-bodied organisms like jellyfish rarely stand the test of time. What's more, it's hard for any animal to get preserved with exceptional detail in sandstones, which are made of large grains, are porous, and commonly form in environments swept by rough storms and waves. But about 570 million years ago, in a geologic time interval called the Ediacaran period, strange-looking, soft-bodied organisms died on the seafloor, were buried in sand, and fossilized in incredible detail.

Why hedgehogs used to be hated‎

Hedgehogs have been part of human culture for thousands of years. Across different societies, they've been symbols of fertility, protection and healing, as well as fear, superstition and suspicion.

Retaining employees as they age is possible with more flexibility‎

Many businesses say they're suffering from labor shortages, but what are their management practices and what measures could be put in place to retain experienced workers?
