A global database documenting the location of critical habitats for sharks, rays, and chimeras has recently expanded to include Australia, with years of extensive research by Charles Darwin University (CDU) contributing to this crucial digital record.
More than 7.5 million people immerse themselves in lakes, rivers, seas and lidos every year in the UK. But getting in the water means getting in pollution too for most outdoor swimmers. Raw sewage was discharged into UK waters for 4.7 million hours during 2024. But sewage is only part of the water pollution problem. Rain washing into rivers and streams contains fertilizers, pesticides and animal waste from farmlands, forever chemicals from car tires, plus drugs from our own bodies. Industry deregulation and privatization have produced a water crisis.
The performance horse industry had a problem: Some of their most beloved and sought-after mares simply couldn't have foals safely. To make matters more complicated, in vitro fertilization (IVF) had not yet produced a healthy equine embryo, despite years of success in other species like cattle.
In the middle of the old-growth forests of Congaree National Park in South Carolina, fireflies put on an otherworldly display every May. Thousands of male insects belonging to the species Photuris frontalis flash together at the same time and follow the exact same pattern—a synchronous light show you can see only in few places in the United States.
Wet wipes conveniently clean and sanitize soiled surfaces and skin. Because some labels do not clearly indicate how consumers should dispose of them, these small cloths are often flushed down the toilet and released by sewage plants into waterways. Now, researchers report in ACS ES&T Water that some of these wipes break down into plastic fibers, or microplastics, that could harm aquatic life.
Dragonfly integration and testing—the activities involved in assembling the mission's rotorcraft lander and testing it for the rigors of launch and extreme conditions of space—is officially underway in clean rooms and control rooms at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.
Wildlife populations that become small and isolated, often due to habitat loss, inevitably experience inbreeding which can lead to the loss of fitness and eventual extinction. One solution is to perform a genetic rescue: a management intervention where new blood is brought in by introducing outsiders to a population to reduce inbreeding and restore diversity. But how do researchers know the inbreeding problem has been solved?
Multiferroic metals are materials that exhibit both electric polarization and magnetic order in the same crystal—a state known as multiferroicity. Because these properties coexist, they can interact through magnetoelectric (ME) coupling, allowing electric fields to influence magnetism.
MLIP calculations successfully identify suitable dopants for a novel photocatalytic material, report researchers from the Institute of Science Tokyo. As demonstrated in their study, published in the Journal of the American Chemical Society, a materials informatics approach could predict which ions can be stably introduced into orthorhombic Sn3O4, a promising and recently discovered photocatalytic tin oxide.
An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary black hole merger, designated S241125n. Remarkably, just seconds later, satellites recorded a short gamma-ray burst (GRB) from the same region of the sky.
