Future Supply Risks of Metals and Metalloids

High-Tech Products Face Future Supply Risks

New research from Yale University details the “criticality” of all 62 metals on the Periodic Table of Elements, providing key insights into which materials might become more difficult to find in the coming decades, which ones will exact the highest environmental costs — and which ones simply cannot be replaced as components of vital technologies. […]

Astronomers View an Outbursting Class 0 Protostar

NASA Views Growth Spurt from Newborn Protostar

Satellite and ground-based data has revealed an outburst from HOPS 383. This is the first outburst astronomers have ever seen from a Class 0 object, and it appears to be the youngest protostellar eruption ever recorded. Using data from orbiting observatories, including NASA’s Spitzer Space Telescope, and ground-based facilities, an international team of astronomers has […]

Curiosity Finds Evidence of Nitrates on Mars

Curiosity Finds Biologically Useful Nitrogen on Mars

NASA’s Curiosity rover has discovered evidence of nitrates in scooped samples of windblown sand and dust at the “Rocknest” site, providing further evidence that the ingredients needed for life were present on Mars billions of years ago. Nitrogen is essential for all known forms of life, since it is used in the building blocks of […]

Experimental Evidence That Stars May Generate Sound

Researchers Discover the Sound of Stars

A chance discovery by a team of physicists has provided experimental evidence that stars may generate sound. The study of fluids in motion – now known as hydrodynamics – goes back to the Egyptians, so it is not often that new discoveries are made. However when examining the interaction of an ultra-intense laser with a […]

New MIND Diet May Significantly Lower Risk of Alzheimer’s Disease

MIND Diet May Significantly Protect Against Alzheimer’s Disease

New research from Rush University Medical Center shows that the MIND diet could significantly lower a person’s risk of developing Alzheimer’s disease. A new diet, appropriately known by the acronym MIND, could significantly lower a person’s risk of developing Alzheimer’s disease, even if the diet is not meticulously followed, according to a paper published online […]

Researchers Develop a Better Method for Making Perovskite Solar Cells

Faster, Cooler, Thinner, Better Perovskite Solar Cells

Using perovskite, engineers from Brown University have developed a cheap, efficient alternative to silicon-based solar cells. Providence, Rhode Island (Brown University) — Research led by a Brown University Ph.D. student has revealed a new way to make light-absorbing perovskite films for use in solar cells. The new method involves a room-temperature solvent bath to create […]

Transiting Exoplanet Survey Satellite – The Search for Planets Outside Our Solar System

TESS — Transiting Exoplanet Survey Satellite

The Transiting Exoplanet Survey Satellite (TESS) is set to discover thousands of exoplanets in orbit around the brightest stars in the sky. The Transiting Exoplanet Survey Satellite (TESS) is an Explorer-class planet finder. In the first-ever spaceborne all-sky transit survey, TESS will identify planets ranging from Earth-sized to gas giants, orbiting a wide range of […]

Terra Satellite Sees Shadows of Solar Eclipse in the Arctic Ocean

Terra Satellite Views Shadows of Solar Eclipse

NASA’s Terra satellite captured this view of the clouds in the Arctic Ocean during last week’s total solar eclipse. During the morning of March 20, 2015, a total solar eclipse was visible from parts of Europe, and a partial solar eclipse from northern Africa and northern Asia. NASA’s Terra satellite passed over the Arctic Ocean […]

Hubble Image of the Week – A Galaxy on the Edge

Hubble Views Spiral Galaxy NGC 5023

This newly released Hubble image shows an edge-on view of the spiral galaxy NGC 5023. Due to its orientation we cannot appreciate its spiral arms, but we can admire the elegant profile of its disc. The galaxy lies over 30 million light-years away from us. NGC 5023 is part of the M51 group of galaxies. […]

“Chemical Fingerprints” Could Help Scientists Recognize Life on the Surface of Exoplanets

Surface Biosignatures of Exoplanets May Help Detect Extraterrestrial Life

A new catalog of reflectance spectra for a diverse range of pigmented microorganisms may help scientists recognize life on the surface of planets orbiting stars beyond our solar system. A team of astronomers and biologists has recorded the “chemical fingerprints” of 137 different species of microorganism. In future, this could help to recognize life on […]

Carnufex Carolinensis – North America’s Top Predator Before Dinosaurs?

Carnufex Carolinensis

New research from North Carolina State University shows that a 9-foot long crocodile ancestor may have been North America’s top predator before the dinosaurs arrived. A newly discovered crocodilian ancestor may have filled one of North America’s top predator roles before dinosaurs arrived on the continent. Carnufex carolinensis, or the “Carolina Butcher,” was a 9-foot […]

Astronomers Use Globular Clusters to Measure Galaxy Evolution

Measuring Galaxy Evolution

A new study from the Harvard-Smithsonian Center for Astrophysics reveals that globular clusters are often gathered into distinct groupings whose shapes reflect the formation of the clusters and the histories of the galaxies. Globular clusters are gravitationally bound ensembles of stars, as many as a million stars in some cases, grouped in roughly spherical clusters […]

SOFIA Reveals Missing Link Between Supernovae and Planet Formation

Missing Link Between Supernovae and Planet Formation

A newly published study reveals that supernovae are capable of producing enough material to form planets. Using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), an international scientific team discovered that supernovae are capable of producing a substantial amount of the material from which planets like Earth can form. These findings are published in the March […]
