Researchers developed a novel electrode that effectively suppresses the harmful self-discharge phenomenon in flowless zinc-bromine batteries. The flowless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries due to its use of non-flammable electrolytes...

Europe’s next big space mission – a telescope that will hunt for Earth-like rocky planets outside of our solar system — is on course to launch at the end of 2026.

PLATO, or PLAnetary Transits and Oscillations of stars, is being built to find nearby potentially habitable worlds around Sun-like stars that we can examine in detail.

The space telescope will blast into orbit on Europe’s new rocket, Ariane-6, which made its maiden flight last week after being developed at a cost of €4billion (£3.4billion).

Dr David Brown, of the University of Warwick, is giving an update on the mission at the Royal Astronomical Society’s National Astronomy Meeting at t...

Study identifies RNA molecule that Regulates Cellular Aging

SNORA13 (red) in the nucleus of senescent human cells
This shows SNORA13 (red) in the nucleus of senescent human cells within a specialized structure called the nucleolus where ribosomes are assembled. DNA is stained in blue.

A team led by UT Southwestern Medical Center researchers has discovered a new way that cells regulate senescence, an irreversible end to cell division. The findings, published in Cell, could one day lead to new interventions for a variety of conditions associated with aging, including neurodegenerative and cardiovascular diseases, diabetes, and cancer, as well as new therapies for a collection of diseases known as ribosomopathies.

“There is great interest in reducing senescence to slow or reverse aging or aging-associated diseases...

Paving the way to Extremely Fast, Compact Computer Memory

Illustration showing two corkscrew-shaped lines twisting in opposite directions, rising up out of a layer of small spheres that represent atoms, each with an arrow pointing in the direction of a feature called its magnetic moment
When researchers irradiate a thin layer of nickel iodide with an ultrafast laser pulse, corkscrew-shaped features called “chiral helical magnetoelectric oscillations” arise. These features could be useful for a range of applications, including fast, compact computer memories. Image: Ella Maru Studio.

Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.

For decades, scientists have been studying a group of unusual materials called multiferroics that could be useful for a range of applications including computer memory, chemica...
