For many years, chili has been hailed for its therapeutic properties, and now researchers have found that eating chili peppers regularly can cut the risk of death from heart disease and stroke.
Carried out in Italy, where chili is a common ingredient, the study compared the risk of death among 23,000 people, some of whom ate chili and some of whom didn’t.
An organized tide of brain waves, blood and spinal fluid pulsing through a sleeping brain may flush away neural toxins that cause Alzheimer’s and other diseases.
Teams have looked for a “fifth force” in the universe within the Earth’s mantle, ultra-vacuum chambers, and in hypothetical particles such as “X17.” Finding it could help explain mysteries around dark matter and dark energy.

A small study reveals that rapamycin, a drug with a long history as an immune suppressor, can improve tone and reduce wrinkles and sagging in human skin.
A physicist from RUDN University has proposed a new theoretical model for the interaction of spinor and gravitational fields. He considered the evolution of the universe within one of the variants of the widespread Bianchi cosmological model. In this case, a change in the calculated field parameters led to changes in the evolution of the universe under consideration. Upon reaching certain values, it began to shrink down to the Big Bang. The article was published in the journal The European Physical Journal Plus.
The spinor field is characterized by its behavior in interaction with gravitational fields. Dr. Bijan Saha of RUDN University focused on the study of a nonlinear spinor field. With its help, he explained the accelerated expansion of the universe. The study of a spinor field with a non-minimal coupling made it possible to describe not only the expansion of the universe, but also its subsequent contraction and the resulting Big Bang within the framework of the standard Bianchi cosmological model.
The basic calculations performed by Bijan Saha allow moving away from the isotropic model of the Friedman-Robertson-Walker universe (FRW) that is most often used. According to this traditional model, the properties of the universe are independent of the direction in which they are considered. The physicist has put forward an alternative: an anisotropic model in which such dependence exists. On the one hand, the “classical” isotropic model describes the evolution of the modern universe with great precision. On the other hand, there are theoretical arguments and observational data that lead to the conclusion that an anisotropic phase existed in the distant past.
In an article published in Physical Review Letters, Bristol scientists have answered the fundamental question: “Is it possible to move without exerting force on the environment?”, by describing the tractionless self-propulsion of active matter.
Understanding how cells move autonomously is a fundamental question for both biologists and physicists.
Experiments on cell motility are commonly done by looking at the motion of a cell on a glass slide under a microscope.
With collagen supplements you can regrow cartilage pretty easily. Most supplements work better than medicine when it comes to tissue repair.
Humans have the ability to regrow cartilage, a new study has found.
In a way similar to how salamanders and other creatures can regrow lost limbs, humans have the capacity to repair and regenerate cartilage in their joints, researchers at Duke Health discovered.
“We believe that an understanding of this ‘salamander-like’ regenerative capacity in humans, and the critically missing components of this regulatory circuit, could provide the foundation for new approaches to repair joint tissues and possibly whole human limbs,” said senior author Virginia Byers Kraus, a professor in the departments of medicine, pathology and orthopedic surgery at Duke.
