How Down Syndrome and Low SNX27 Are Connected

How Down Syndrome and Low SNX27 Are Connected

In a newly published study, researchers show how Down syndrome and low SNX27 are connected, discovering that the extra chromosome inherited in Down syndrome impairs learning and memory because it leads to low levels of SNX27 protein in the brain. What is it about the extra chromosome inherited in Down syndrome—chromosome 21—that alters brain and […]

Volcanic Activity Triggered the End-Triassic Extinction

Volcanic Eruptions Triggered the End Triassic Extinction

In a new study, researchers from MIT provide evidence that volcanic activity did indeed trigger the end-Triassic extinction, killing off 76 percent of marine and terrestrial species on Earth. More than 200 million years ago, a massive extinction decimated 76 percent of marine and terrestrial species, marking the end of the Triassic period and the […]

Researchers Study Early Galaxies and Their Specific Properties

The Shape of Galaxies in the Early Universe

Using data from the CANDELS project, scientists examine early galaxies and their specific properties, finding that star formation in blue galaxies have undergone collisions that induce star formation that makes them shine exceptionally brightly. Galaxies today come very roughly in two types: reddish, elliptically shaped collections of older stars, and bluer, spiral shaped objects dominated […]

Metamaterials Amplify the Photonic Spin Hall Effect

Researchers Use Metamaterials to Observe Giant Photonic Spin Hall Effect

Using metamaterial surfaces, researchers were able to amplify the signal of the photonic Spin Hall Effect, making it directly observable with simple detection techniques, and control the propagation of light and circular polarization. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of […]

‘Sideline Quasars’ Helped Suppress Early Galaxy Formation

Sideline Quasars Helped to Stifle Early Galaxy Formation

A newly published study from astronomers at the University of Colorado Boulder suggests that distant quasars teamed up to stifle the formation of small galaxies billions of years ago. University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the universe some 11 billion years ago say “sideline quasars” likely teamed up […]
