Only half of England's young workers outside higher education secure permanent contracts, down from 81%‎

The study of young people in England found that among those who did not progress to higher education, only 16% secured apprenticeships and just 23% had secured stable work by ages 19–20. Of those in work, only half had a permanent contract, down from 81% in a similar study six years ago.

Retired ocean liner to become largest artificial reef in the world‎

Bigger than the RMS Titanic and faster than the RMS Queen Mary, the SS United States was a nautical wonder during the mid-20th century—the nation's premier luxury ocean liner that once ferried presidents and Hollywood elite across the Atlantic in opulence.

Microplastics found in wild mammals' blood more than 40 miles from human infrastructure‎

Animals, like humans, are taking up increasing amounts of tiny plastic particles. Such microplastics are demonstrably hazardous to many species under experimental conditions, and it is suspected that they may also pose a threat to animals in the wild. While data about microplastic concentrations in the terrestrial environment exist, it has not yet been clear if higher exposure also translates into higher microplastic accumulation in individual animals. A new paper published in Nature now confirms this link.

New study maps the genetic landscape of bovine TB across Wales‎

Bovine tuberculosis is evolving in different ways across different regions in Wales, according to the most detailed analysis of the bacterium conducted to date. One of the most significant animal health challenges facing Wales, bovine TB affects cattle health and farm businesses and places considerable emotional, social and financial pressures on farming communities.

Even parasites have parasites: Fungus infects powdery mildew‎

In the fungal kingdom, no one is safe from parasites—not even other parasites. A new study from North Carolina State University finds that Ampelomyces, an intracellular fungus that infects the plant disease powdery mildew, is far more common than previously known. By screening museum samples of powdery mildews up to about 150 years old, researchers discovered that not only is Ampelomyces quite common, but many specimens labeled as Ampelomyces are misidentified.

Independent technique validates landmark M87* image‎

The 2019 Event Horizon Telescope (EHT) image was the work of hundreds of scientists and captured the first direct view of a black hole's shadow—becoming one of the most recognized scientific images of the modern era. A team of four from CSIRO, Australia's national science agency, has developed a powerful new imaging technique that validated the landmark 2019 image of the black hole at the center of galaxy M87.

Clean water, hidden risks: New technology reveals neurotoxicity missed by conventional water quality monitoring‎

A photograph of an orchestra can tell you whether the musicians are on stage and their instruments are intact. But it cannot tell you whether they are playing in harmony. Even when every musician is present, a subtle loss of coordination can change the entire performance.

What lurks 'Below' Newfoundland waters? A marine biologist explains the science behind the show‎

When I learned that Netflix planned to film the miniseries Below, about a sea monster terrorizing a Newfoundland outport, I thought to myself: "THIS I've gotta see!"

Fluorescent probes reveal fluid-like barriers inside nuclear pores of living human cells‎

Our genetic material is hidden inside the nucleus of our cells, well protected by a double membrane. All molecules wishing to pass through must thread their way through one of several thousand nuclear pores. The scaffold structure of these pores is well known. However, exactly how transport takes place within them has been the subject of much debate. Researchers at Johannes Gutenberg University Mainz (JGU), the Max Planck Institute for Biophysics (MPI-BP) in Frankfurt am Main and Wuhan University in China have now shed light on the matter.

Superconducting vortices provide experimental evidence that clogging is a phase transition‎

Clogging is a phenomenon in which moving particles get stuck, slowing or blocking the flow, but how this transition occurs has remained experimentally unproven. Researchers from Science Tokyo studied superconducting vortices to demonstrate that clogging is a nonequilibrium phase transition. Using a two-step measurement protocol, they distinguished clogging from conventional pinning and revealed that both transitions share a critical point, offering new insights into predicting and controlling clogging across diverse systems.
