Located about 440 light-years from Earth, Zeta Ophiuchi is a hot star with a complicated past. The star is 20 times more massive than the Sun, likely being ejected from its birthplace by a powerful stellar explosion. According to earlier measurements, Zeta Ophiuchi was expelled at a speed of around 100,000 miles per hour when
Hair follicles are mini skin organs that undergo cyclic growth. Various signals regulate the hair follicles fate decisions jointly. A new study reported the discovery of a single chemical that controls when hair follicle cells divide and when they die. This discovery is expected to treat baldness and accelerate wound healing because follicles are a
As the number of people with diabetes worldwide exceeds 500 million, scientists must find ways to improve a limited number of available medications with unclear effectiveness. A new study by Monash University is an important step forward toward developing new therapies. Scientists have discovered a pathway to the regeneration of insulin in pancreatic stem cells.
The most crucial factor in safeguarding a car surface is the excellent durability of automotive coatings. Protective coating materials should also be transparent and colorless to preserve the product’s natural color. However, it isn’t easy to provide a self-healing function while satisfying all of these conditions. Existing commercially available materials have some limitations. Materials with
One method to study our Galactic origins is to study the earliest building blocks of the Milky Way by searching for and analyzing galaxies forming in the early Universe. NASA’s JWST is the ideal machine to push our cosmic horizons to the epoch of the first galaxies. Two brand-new pictures taken by NASA’s James Webb
The monkeypox outbreak has been declared a global health emergency by the World Health Organization. More than 16,000 cases have now been reported from 75 countries. The first outbreak of Monkeypox emerged in 2003. In this outbreak, all people infected with Monkeypox became ill after contacting pet prairie dogs. A new study published in The
All laws of physics can be expressed mathematically as connections between state variables. This set of variables provides a thorough and non-redundant description of the system at hand. The actual process of detecting the hidden state variables has defied automation, despite processing power and artificial intelligence availability. Most data-driven methods for modeling physical phenomena still
Triple-negative breast cancer (TNBC) is an aggressive subtype associated with early metastatic recurrence and worse patient outcomes. The tumor expresses molecular markers of the epithelial-mesenchymal transition, but its requirement during spontaneous TNBC metastasis in vivo remains incompletely understood. Scientists from Johns Hopkins Medicine have identified significant molecular variations between cancer cells that cling to an
Observing the birth of the first stars and galaxies has been a goal of astronomers for decades. It will explain the evolution of the Universe. The University of Cambridge‘s team has created a technique that will enable them to see and study the first stars through the hydrogen clouds that covered the Universe some 378,000
It was thought that surface regeneration on asteroids must take a few millions of years. However, a new study by surprised scientists suggests- it happens so quickly. Scientists from NASA’s OSIRIS-REx mission recently learned that surface regeneration happens much quicker on asteroids than on Earth. By analyzing images of the asteroid (101955) Bennu obtained by
