EAST Fusion Facility Exceeds Fusion Plasma Density Limit New Plasma Regime: The Chinese fusion reactor EAST has overcome a crucial density limit for fusion plasma, achieving the so-called density-free regime for the first time. This allows the plasma to be compressed to a higher density without dangerous instabilities occurring near the reactor vessel walls. The EAST fusion facility thus paves the way for the extreme conditions necessary for nuclear fusion. The EAST (Experime

Neurons Store Memory Content and Context Separately Neural division of labor: Our brain doesn't store past experiences and their context together, but rather in two separate groups of brain cells, as an experiment reveals. Only the combination of both creates a complete memory. Content neurons, therefore, store only the information itself, such as an object or a person. Context neurons, on the other hand, only remember the circumstances. This division of labor makes our memor

The Oral Bacterium Streptococcus anginosus Also Promotes Stomach Cancer Microbes as Cancer Triggers: It is well known that Helicobacter pylori can cause stomach cancer. But there is another culprit: The bacterium Streptococcus anginosus also promotes the growth of cancerous tumors in the stomach, as a new study has confirmed. According to the study, this microbe is not only found in increased numbers in stomach cancer ulcers, but it also releases methionine, a molecule that f

Special Ink Developed for Camouflage Technologies and Wearable Electronics Printable Metamaterial: A liquid metal-based ink could help develop flexible invisibility cloaks in the future. It can be printed onto various materials, remains soft, and can be stretched to 120 times its original dimensions—while still maintaining its electrical conductivity and stability. Surfaces printed with this ink can redirect electromagnetic waves. This could, for example, make robots invisibl

Combination of Closeness and Cuddle Hormone Can Be Healing Healing through love? Superficial skin injuries heal faster when the cuddle hormone oxytocin is circulating in our bodies. However, this only works if the elevated hormone level is accompanied by physical and emotional closeness, as a study shows. According to the study, loving attention and oxytocin together can promote wound healing, but they do not act as independent remedies. In the test subjects, superficial skin

Zinc Deprivation Inhibits Fungal Infection of Mucous Membranes A Matter of Balance: The yeast Candida albicans colonizes our mucous membranes. Researchers have now discovered why this is highly dangerous under certain conditions, but remains harmless in most cases. According to their findings, the immune system deprives the fungus of the necessary zinc, thereby inhibiting both toxin production and the proliferation of yeast cells. However, if the immune system is weakened, Ca
