Researchers from the Faculty of Physics at the University of Warsaw, the Military University of Technology (Poland), IBM Research Zurich and the French National Centre for Scientific Research (CNRS) have observed a new quantum state of matter known as a supersolid in an exciton-polariton Bose-Einstein condensate. Remarkably, the phenomenon occurs not at temperatures close to absolute zero, but at room temperature. The results have been published in Science Advances.

How can a liquid also be a crystal?
At first glance, this seems impossible...

Researchers at the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute have discovered a group of particularly long-lived blood stem cells in mice. These cells remain in a dormant state for an exceptionally long time while retaining their ability to generate new blood cells. This newly discovered cell population may be responsible for sustaining blood regeneration and immune defense throughout a mouse’s entire life.

Our bodies produce billions of new blood cells every day. These cells transport oxygen, fight pathogens and help stop bleeding. Blood stem cells in the bone marrow are responsible for this vital replenishment. They can renew themselves and produce all types of blood cells—for a lifetime.

To prevent this ability from being exhausted prematurely,...

Scientists examining data collected by NASA’s Hubble Space Telescope have found that dozens of small galaxies contain far less oxygen than their stars are estimated to have produced. The researchers, including a Rutgers astrophysicist, studied 37 dwarf galaxies, which are much smaller than the Milky Way and considered to be nearby, within 22 million light-years of Earth. The results were published in The Astrophysical Journal.

Members of the team compared estimates of how much oxygen the galaxies’ stars had made over their lifetimes with the amount remaining ...

A study of nearly 13,000 adults found that people consuming the most artificial sweeteners experienced a 62% faster decline in memory and thinking skills, equivalent to approximately 1.6 additional years of brain aging. Six popular sweeteners were linked to faster cognitive decline, raising concerns about the long-term brain health effects of common sugar substitutes, although causation was not established.

Sugar substitutes are often promoted as a healthier way to enjoy sweet foods and drinks without consuming as much sugar...
