Scientists are developing greener plastics – the bigger challenge is moving them from lab to market

Scientists are developing greener plastics – the bigger challenge is moving them from lab to market Used once and done. Michael Coghlan, CC BY-SA Richard Gross, Rensselaer Polytechnic Institute Synthetic plastics have made many aspect of modern life cheaper, safer and more convenient. However, we have failed to figure out…

Astronomers using ALMA have uncovered chemical “fingerprints” of methanol, dimethyl ether, and methyl formate in the Large Magellanic Cloud. The latter two molecules are the largest organic molecules ever conclusively detected outside the Milky Way. The far-infrared image on the left shows the full galaxy. The zoom-in image shows the star-forming region observed by ALMA. It is a combination of mid-infrared data from Spitzer and visible (H-alpha) data from the Blanco 4-meter telescope.

Stellar Embryos in Nearby Dwarf Galaxy Contain Surprisingly Complex Organic Molecules

Stellar Embryos in Nearby Dwarf Galaxy Contain Surprisingly Complex Organic Molecules The nearby dwarf galaxy known as the Large Magellanic Cloud (LMC) is a chemically primitive place. Unlike the Milky Way, this semi-spiral collection of a few tens-of-billions of stars lacks our galaxy’s rich abundance of heavy elements, like carbon,…
