Potassium supplements in salt were associated with reduced rates of recurrent stroke and mortality in a large-scale cluster randomized clinical trial involving patients in rural northern China. Findings come from a subgroup (stroke patients) analysis within the original Salt Substitute and Stroke Study (SSaSS), an international study conducted in China.

Stroke ranks among the top causes of death and disability in low- and middle-income countries, and recurrent events remain a major concern. High sodium intake and low potassium intake are considered key risk factors, especially in northern China. In China, stroke recurrence rates are higher than global averages, reaching 17% at one year and 41% over five years.

The SSaSS trial involved 600 villages and 20...

Entanglement—linking distant particles or groups of particles so that one cannot be described without the other—is at the core of the quantum revolution changing the face of modern technology.

While entanglement has been demonstrated in very small particles, new research from the lab of University of Chicago Pritzker School of Molecular Engineering (UChicago PME) Prof. Andrew Cleland is thinking big, demonstrating high-fidelity entanglement between two acoustic wave resonators.

The paper is published in Nature Communications.

“A lot of research groups have demonstrated that they can enta...

Using the Hubble Space Telescope (HST), astronomers have observed a supermassive galactic open cluster designated Westerlund 1. Results of the study, published Jan. 28 on the pre-print server arXiv, yield essential details regarding the structure of this cluster.

Open clusters (OCs), formed from the same giant molecular cloud, are groups of stars loosely gravitationally bound to each other. It is assumed that most star formation takes place in massive clusters of stars, known as superstar clusters (SSCs). They are very massive young OCs usually containing a very large number of young, massive stars. The total mass of a typical SSC exceeds 10,000 solar masses.

Westerlund 1 is a supermas...

A biomaterial that can mimic certain behaviors within biological tissues could advance regenerative medicine, disease modeling, soft robotics and more, according to researche(rs at Penn State.

Materials created up to this point to mimic tissues and extracellular matrices (ECMs) — the body’s biological scaffolding of proteins and molecules that surrounds and supports tissues and cells — have all had limitations that hamper their practical applications, according to the team...
