Fine-Tuning the Chemistry of Materials

Controlling Chemical Binding Properties Improves Structurally Complex Materials like Concrete

Using sophisticated calculations that show how atomic-level forces affect the mechanical properties of a complex particle-based material, researchers from Rice University reveal new ways to improve the chemistry of materials like concrete to make it less prone to cracking and more suitable for specific applications. Even when building big, every atom matters, according to new […]

Yale Study Explains How We Live in Harmony With Gut Bacteria

How We Live in Harmony With Gut Bacteria

New research from Yale University identifies a strategy that non-harmful gut bacteria employ to preserve this stable relationship with their host during inflammation. Stability in the composition of the hundred trillion bacterial cells in the human gastrointestinal tract is crucial to health, but scientists have been perplexed how our microbiota withstands an onslaught of toxins, […]

“Machine Learning” Helps Astronomers Identify Basic Properties of Stars

A Machine Learning Method to Learn About the Stars

A newly published study details how astronomers have turned to a method called “machine learning” to help them understand the properties of large numbers of stars. Astronomers are enlisting the help of machines to sort through thousands of stars in our galaxy and learn their sizes, compositions and other basic traits. The research is part […]

NuSTAR Views Colliding Galaxies, Arp 299

NAS Views Colliding Galaxies Arp 299

This newly released image from NASA’s Nuclear Spectroscopic Telescope Array shows two colliding galaxies, collectively called Arp 299, located 134 million light-years away. Each of the galaxies has a supermassive black hole at its heart. NuSTAR has revealed that the black hole located at the right of the pair is actively gorging on gas, while […]

Scientists Pinpoint the Position of Saturn

Researchers Pinpoint the Position of Saturn

Using a giant array of radio-telescope antennas and data from NASA’s Cassini spacecraft, astronomers have made the most accurate determinations yet of the position of the center of mass, or barycenter, of Saturn and its numerous moons. Scientists have paired NASA’s Cassini spacecraft with the National Science Foundation’s Very Long Baseline Array (VLBA) radio-telescope system […]

Study Identifies Which Fossil Fuels Must Remain in the Ground to Limit Global Warming

Some Fossil Fuels Must Remain in the Ground to Limit Global Warming

New research led by the University College London shows that a third of oil reserves, half of gas reserves and over 80% of current coal reserves globally should remain in the ground and not be used before 2050 if global warming is to stay below the 2°C target agreed by policy makers. The study funded […]

Study Shows Diabetes Risk Varies with Mg Intake, Genes and Ethnicity

Study Links Magnesium Intake to Diabetes

New research from Brown University investigates the complex interactions between magnesium intake, genes, and ethnicity in determining risk for type 2 diabetes in African American and Hispanic American Women. Providence, Rhode Island (Brown University) — Magnesium is an important nutrient, in part because it appears to help regulate insulin secretion and/or action. Sure enough, studies […]

Researchers May Have Pinpointed a Strategy for Eliminating Latent HIV

Study Shows Broad Immune Response May be Needed to Destroy Latent HIV

A newly published study shows promise as the future direction for the development of a therapeutic vaccine to clear HIV. A major barrier to finding a cure for HIV/AIDS is the presence of latent HIV in the cells of chronically infected individuals. But a team of Yale and Johns Hopkins researchers may have pinpointed a […]

Astronomers Discover a Possible Distant Black Hole Merger

Astronomers Find Distant Black Hole Merger

In a newly published study, a team of astronomers detail an unusual repeating light signal from a distant quasar that they say is most likely the result of two supermassive black holes in the final stages of a merger – something that is predicted from theory but which has never been observed before. The central […]

ESO Views Lynds Dark Nebula 483

New ESO Image of Lynds Dark Nebula 483

This newly released ESO image shows Lynds Dark Nebula 483, which is located about 700 light-years away in the constellation of Serpens. Some of the stars appear to be missing in this intriguing new ESO image. But the black gap in this glitteringly beautiful starfield is not really a gap, but rather a region of […]

HARPS-N Spectrograph Reveals the Composition of Terrestrial Planets

Astronomers Reveal New Recipe for Other Earths

Using the High-Accuracy Radial velocity Planet Searcher (HARPS), astronomers show that the recipe for Earth also applies to terrestrial exoplanets orbiting distant stars. Cambridge, Massachusetts – How do you make an Earth-like planet? The “test kitchen” of Earth has given us a detailed recipe, but it wasn’t clear whether other planetary systems would follow the […]
