Neutrons paint atomic portrait of prototypical cell signaling enzyme

Oak Ridge National Laboratory

Direct observations of the structure and catalytic mechanism of a prototypical kinase enzyme—protein kinase A or PKA—will provide researchers and drug developers with significantly enhanced abilities to understand and treat fatal diseases and neurological disorders such as cancer, diabetes, and cystic fibrosis. The discovery was made by an international team of researchers using macromolecular neutron crystallography at the Department of Energy’s Oak Ridge National Laboratory and the Institut Laue-Langevin in Grenoble, France.

Robotic “Gray Goo”

Columbia University School of Engineering and Applied Science

Researchers at Columbia Engineering and MIT Computer Science & Artificial Intelligence Lab (CSAIL), demonstrate for the first time a way to make a robot composed of many loosely coupled components, or “particles.” Unlike swarm or modular robots, each component is simple, and has no individual address or identity. In their system, which the researchers call a “particle robot,” each particle can perform only uniform volumetric oscillations (slightly expanding and contracting), but cannot move independently.

The Best Topological Conductor Yet: Spiraling Crystal Is the Key to Exotic Discovery

Lawrence Berkeley National Laboratory

A team of researchers working at Berkeley Lab has discovered the strongest topological conductor yet, in the form of thin crystal samples that have a spiral-staircase structure. The team’s result is reported in the March 20 edition of the journal Nature.

Predicted deforestation in Brazil could lead to local surface temperature increase of up to 1.45°C by 2050

PLOS

A new model quantifies how forest change affects local surface temperatures by altering sunlight-reflection and evapotranspiration properties, and predicts that Brazilian deforestation could result in a 1.45°C increase by 2050, in a study published March 20, 2019 in the open-access journal PLOS ONE by Jayme A. Prevedello from the Rio de Janeiro State University, Brazil, and colleagues.

2019 APS April Meeting: Preliminary Highlights & Last Call for Hotel Registration

American Physical Society (APS)

Information on the 2019 American Physical Society April Meeting in Denver, which explores research from “Quarks to Cosmos.” It runs from Saturday, April 13 through Tuesday, April 16 at the Sheraton Denver Downtown Hotel. At the meeting, the latest breaking research in particle and astrophysics will be presented -- from long views of massive, ancient objects in the universe to short-lived, subatomic interactions. The meeting will also feature thoughtful presentations by experts in education, policy, the history of physics, and many other areas.
