New protocluster of massive quiescent galaxies discovered
An international team of astronomers reports the discovery of a new protocluster of massive quiescent galaxies at a redshift of approximately 4.0. This is the first detection of a protocluster of this type at such a high redshift. The finding was detailed in a paper published Nov. 20 on the pre-print...

Polygenic prediction of educational attainment within and between families from genome-wide association analyses in 3 million
We conduct a genome-wide association study (GWAS) of educational attainment (EA) in a sample of ~3 million individuals and identify 3,952 approximately uncorrelated genome-wide-significant single-nucleotide polymorphisms (SNPs). A genome-wide polygenic predictor, or polygenic index (PGI), explains 12–16%...

Simulations suggest Earth's oxygen-rich atmosphere will last only another billion years
A pair of researchers from Toho University and NASA Nexus for Exoplanet System Science has found evidence, via simulation, that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. In their paper published in the journal Nature Geoscience, Kazumi Ozaki and Christopher Reinhard...

The Namib Desert bears a scar from a meteorite impact.
"In the vastness of one of the world’s oldest deserts lies a relatively recent geologic feature: the Roter Kamm crater (“red comb” or “red crest/ridge” in German). An astronaut onboard the International Space Station photographed the crater while orbiting over the Namib Desert. It is approximately...

Evolution seems to have occurred a million times faster than natural selection alone could explain. Could nature be using
Evolution seems to have occurred a million times faster than natural selection alone could explain. Could nature be using some hidden process? Just read Probably Approximately Correct by Leslie Valiant (a computational theorist). It explores a special class of algorithms which he calls 'ecorthims' that...

Zimbabwe on track to achieve virtual elimination of mother-to-child transmission of HIV: In 2010, when the project began,
Zimbabwe on track to achieve virtual elimination of mother-to-child transmission of HIV: In 2010, when the project began, Zimbabwe had one of the highest burdens of new HIV infections in the world, with a mother-to-child HIV transmission rate of approximately 30 percent. Today, the rate of transmission...
