A method that adds a heat treatment after 3D printing of titanium alloys could allow for fast fabrication of strong parts.

NASA’s DART mission is on course to slam into the asteroid Dimorphos on Monday.

ABSTRACT In the paired data setting, the sign test is often described in statistical textbooks as a test for comparing differences between the medians of two marginal distributions. There is an implicit assumption that the median of the differences is equivalent to the difference of the medians when employing the sign test in this fashion. We demonstrate however that given asymmetry in the bivariate

President Jair Bolsonaro is up for re-election, but his policies failed to slow the coronavirus’s spread.

Abstract The Bayesian-frequentist hybrid model and associated inference can combine the advantages of both Bayesian and frequentist methods and avoid their limitations. However, except for few special cases in existing literature, the computation under the hybrid model is generally non-trivial or even unsolvable. This paper develops a computation algorithm for hybrid inference under any general loss

DeepMind’s system for predicting the 3D structure of proteins is among five recipients of science’s most lucrative awards.

The ability to programme new modes of catalysis into proteins would allow the development of enzyme families with functions beyond those found in nature. To this end, genetic code expansion methodology holds particular promise, as it allows the site-selective introduction of new functional elements into proteins as non-canonical amino acid side chains.1-4 Here, we exploit an expanded genetic code to

Naturally evolved enzymes, despite astonishingly large variety and function diversity, operate predominantly through thermochemical activation. Integrating prominent photocatalysis modes into proteins such as triplet energy transfer could create artificial photoenzymes that expand the scope of natural biocatalysis.1-3 Here, we exploit genetically reprogrammed, chemically evolved photoenzymes embedded
