Exotic observations with neutrons at the ILL
2025-02-12
In everyday life, we typically encounter water in one of three familiar states – solid, liquid or gas. But there are in fact many more phases, some of which – predicted to exist at high temperature and pressure – are so strange they’re referred to as exotic. State-of-the-art neutron spectrometers and sample environment infrastructures at the Institut Laue-Langevin (ILL) have enabled the first experimental observation of one of these exotic phases – plastic ice VII.
Plastic ice VII was originally predicted more than 15 years ago by molecular dynamics ...

Telehealth may be closing the care gap for people with substance use disorder in rural areas
2025-02-12
Recognition of telehealth as an effective strategy for delivering treatment for substance use disorder (SUD) has raised hopes for improving access to this treatment in settings with limited transportation or when time constraints compromise regular use of consistent access to in-person substance use treatment.
But the findings from a team of researchers from the Virginia Center for Health Innovation, UCLA, RAND, and MedInsight, Milliman Inc., suggest that the promise of telehealth may vary by insurance and geography.
New research suggests that people who live ...
Stronger, safer, smarter: pioneering Zinc-based dissolvable implants for bone repair
2025-02-12
Monash research could transform how broken bones are treated, with the development of a special zinc-based dissolvable material that could replace the metal plates and screws typically used to hold fractured bones together.
Surgeons routinely use stainless steel or titanium, which stay in the body forever, can cause discomfort and may require follow-up surgeries. A new zinc alloy, designed by Monash biomedical engineers, could solve these problems by being mechanically strong but gentle enough to degrade safely over time while supporting optimal healing.
A study published today in Nature shows the research team’s innovative ...
Could peripheral neuropathy be stopped before it starts?
2025-02-12
An increase in high-fat, high-fructose foods in people’s diets has contributed to a dramatic increase in type 2 diabetes. This, in turn, has led to an increase in peripheral neuropathy — nerve damage, typically in the hands and feet — that causes weakness, loss of sensation and, in some, a stabbing, burning, or tingling pain. About half of people with type 2 diabetes are affected, and of these, about half experience severe neuropathic pain.
The damage begins as axons from sensory neurons begin to retract and disappear from the tissues they innervate. New research from the lab of Clifford Woolf, MB, BCh, PhD, director ...

Tidal energy measurements help SwRI scientists understand Titan’s composition, orbital history
2025-02-12
SAN ANTONIO — February 12, 2025 —Southwest Research Institute (SwRI) scientists are studying Saturn’s moon Titan to assess its tidal dissipation rate, the energy lost as it orbits the ringed planet with its massive gravitational force. Understanding tidal dissipation helps scientists infer many other things about Titan, such as the makeup of its inner core and its orbital history.
“When most people think of tides they think of the movement of the oceans, in and out, with the passage of the Moon overhead, said Dr. Brynna Downey. “But that is just because water moves ...
Data-driven networks influence convective-scale ensemble weather forecasts
2025-02-12
To effectively present the uncertainty of convective-scale weather forecasts, convective-scale ensemble prediction systems have been developed at major operational centers, whose lateral boundary conditions are usually provided by global numerical weather models. Recently, the emergence of AI weather models has provided a new approach to driving convective-scale ensemble prediction systems. AI weather models can produce forecasts for the next 7 to 10 days in just a few minutes, which is around 10,000 times faster than numerical weather models. However, the performance of using the ...
