Researchers observed more than 20-year-old data and found that Earth’s atmosphere extends up to 630,000 kilometers away. However, astronomers would still call it a vacuum because it contains very less amount of hydrogen atoms. Earth’s...
The new microscope exploits the reflection of X-ray radiation on magnetic materials. It pinpoints the exact structure and composition of a sample, as well as the elements causing magnetism. Nickel, cobalt and iron alloys look almost the same to an...
Scientists discover a strange type of crystal whose existence was considered impossible before the 1980s. It’s a new kind of quasicrystal that self-assembles from a single component. Quasicrystals are special objects. They consist of ordered...
Researchers used natural language processing and machine learning methods to recognize alcohol misusers from clinician notes in electronic health records. In 78% of cases, AI was able to distinguish between trauma patients who misused alcohol and...
Compared to men, women are more likely to stay mentally sharp in old age. Their brains are more youthful (metabolically neotenous) than men’s throughout the adult lifespan. The aging of the human brain is characterized by several factors...
Researchers detected specific types of microbes in the human gut that were associated with mental health conditions. They developed a framework that can easily identify such bacteria and reveal the mechanism involved in this connection with the...
Researchers found a groundbreaking technique to alter the electronic structure of a copper atom. They made copper catalysts exhibit noble metal-like chemical characteristics. The new material cannot replace an original gold element, but it...
In the last 20 years or so, it seems like a new exoplanet has been discovered almost on a daily basis. The term exoplanet is used to classify those planets which have extrasolar (outside our solar system) origins. Although the first-ever confirmed...
DARPA announced a new program named MACH that seeks to build new design and materials for hypersonic vehicles. The aim is to develop sharp leading edge solutions that can handle high heat fluxes and deliver performance beyond the existing carbon...
Researchers create a precise 3D map of the Milky Way out to its far outer zones. The new map shows that the S-shaped disc of stars becomes progressively warped and twisted the further away the stars are from the center of the Milky Way. We...
A novel smartphone imaging algorithm allows untrained users to analyze complex assays, such as HIV, ovarian cancer antigens, and tuberculosis DNA. It works by generating a mean pixel intensity with small variances and a high dynamic range. ...
The magnetic field of our Sun behaves quite differently than presently believed. The sound waves originating from the Sun’s internal acoustic oscillations affect the magnetic waves at its surface. These waves make the entire corona vibrate...
