“Young” immune cells created by Cedars-Sinai investigators reversed signs of aging and Alzheimer’s disease in the brains of laboratory mice, according to a study published in the journal Advanced Science.

The immune cells, which were produced from human stem cells, could be used to develop new treatments for neurological conditions in humans.

“Previous studies have shown that transfusions of blood or plasma from young mice improved cognitive decline in older mice, but that is difficult to translate into a therapy,” said Clive Svendsen, Ph.D...

A study co-led by ICN2 reveals that ice is a flexoelectric material, meaning it can produce electricity when unevenly deformed. Published in Nature Physics, this discovery could have major technological implications while also shedding light on natural phenomena such as lightning.

Frozen water is one of the most abundant substances on Earth. It is found in glaciers, on mountain peaks and in polar ice caps. Although it is a well-known material, studying its properties continues to yield fascinating results.

An international study involving ICN2, at the UAB campus, Xi’an Jiaotong University (Xi’an) and Stony Brook University (New York), has shown for the first time that ordinary ice is a flexoelectric material.

In other words, it can generate electricity when subjected to mecha...

What can the galactic habitable zone (GHZ), galactic regions where complex life is hypothesized to be able to evolve, teach scientists about finding the correct stars that could have habitable planets?

This is what a recent study accepted for publication in Astronomy & Astrophysics hopes to address as an international team of researchers investigated a connection between the migration of stars, commonly called stellar migration, and what this could mean for finding habitable planets within our galaxy...

Like bees breathing life into gardens, providing pollen and making flowers blossom, little cellular machines called mitochondria breathe life into our bodies, buzzing with energy as they produce the fuel that powers each of our cells. Maintaining mitochondrial metabolism requires input from many molecules and proteins—some of which have yet to be discovered.

Salk Institute researchers are taking a closer look at whether mitochondria rely on microproteins—small proteins that have been difficult to find and, consequently, underestimated for their role in health and disease...
