An international team of astronomers has released survey data detailing the chemical fingerprints of over 340,000 stars. The observations could be used to identify stellar bodies that formed alongside our Sun billions of years ago.

ScienceThat ground beef that you're buying may not be 100 percent ground beef. Sometimes, unscrupulous meat producers will mix in ground offal, in order to stretch their beef supply farther. A new technique, however, uses a laser to detect the presence of such cow innards.

An international team of astronomers has completed the deepest spectroscopic survey of the early universe ever undertaken, collecting data on 1,600 galaxies, and discovering 72 previously unknown galaxies.

The ESO’s Very Large Telescope (VLT) has captured a beautiful image of a planetary nebula known as NGC 7009, or the Saturn Nebula, as part of a wider study attempting to unravel the processes that give these vast cosmic clouds of dust and glowing gas their distinctive shape.

ScienceOrdinarily, for the spectral analysis of peoples' blood, urine or saliva samples, lab-based machines costing thousands of dollars are required. Now, however, scientists have created a US$550 3D-printed device that works with a smartphone to do the same tests with just as much accuracy.

ScienceAs tomatoes ripen, they change in color from green to orange to red. Assessing when they're at peak ripeness is done with the naked eye, and is therefore somewhat subjective. Thanks to new research, however, producers may soon be using a laser device to take the guesswork out of the equation.

ScienceMatter’s mysterious twin, antimatter, has become slightly less mysterious, thanks to new research at the CERN particle physics lab. Scientists have measured the optical spectrum of antihydrogen for the first time to check if antimatter behaves as predicted by the Standard Model of particle physics.

MIT scientists may be bringing a new level of accuracy to epidurals, developing a scattered-light sensor that can be embedded in the tip of a needle to ensure anesthesiologists hit the right spot.
-
To help find out if its worth going to a particular asteroid, scientists from Vanderbilt and Fisk Universities are developing a new gamma-ray spectroscope that's capable of scanning asteroids for valuable minerals.

A team of astronomers has made the first observations with a cutting-edge water-hunting instrument. The instrument is not only suited for identifying signatures of water and other molecules in the Milky Way but also in other galaxies.
-
ESO astronomers working from the La Silla Observatory, Chile, have detected the first direct reflection of light from an exoplanet, 51 Pegasi b, orbiting a Sun-like star. Proof of the new method may have profound implications for future exoplanet observations.
-
Astronomers from the Leiden Observatory, Netherlands, and the University of Rochester, New York, have discovered a massive ring system obscuring the light of the young star J1407b.
