The story of an unexpected protein structure

Structure of human NKR-P1 showing the unique dimerization interface. Panel (a) compares crystal structures of the NKR-P1 receptor binding domain dimers. Panel (b) shows a structural comparison of LLT1 (green) and NKR-P1 (cyan) dimers prepared by overlapping only one monomer from each dimer (middle). Although they both share a similar structure, their dimerization mode is … Read more

Unexpected behavior seen in efficient catalysts for clean energy

ACS Catalysis (2022). DOI: 10.1021/acscatal.1c05933″ width=”500″ height=”402″/> Graphical abstract. Credit: ACS Catalysis (2022). DOI: 10.1021/acscatal.1c05933 Researchers from the Weizmann Institute of Science and the US Department of Energy’s (DOE) Brookhaven National Laboratory have investigated the molecular-level dynamics at play when methanol converts to hydrogen via the help of a copper catalyst, with the whole system … Read more

Scientists on the hunt for planetary formation fossils reveal unexpected eccentricities in nearby debris disk

Artist’s impression of the billion-year-old Sun-like star, HD 53143, and its highly eccentric debris disk. The star and a second inner disk are shown near the southern foci of the elliptical debris disk. A planet, which scientists assume is shaping the disk through gravitational force, is shown to the north. Debris disks are the fossils … Read more

Automated synthesis allows for discovery of unexpected charge transport behavior in organic molecules

Automated synthesis platform in the Molecule Marker Lab. Credit: University of Illinois Urbana-Champaign A cross-disciplinary University of Illinois at Urbana-Champaign (UIUC) team has demonstrated a major breakthrough in using automated synthesis to discover new molecules for organic electronics applications. The technology that enabled the discovery relies on an automated platform for rapid molecular synthesis at … Read more

Unexpected light behavior may be harnessed to improve optical communications and sensors

The NIST team directed light into an ultrathin layer of silicon nitride etched with grooves to create a diffraction grating. If the separation between the grooves and the wavelength of light is carefully chosen, the intensity of light declines much more slowly, linearly rather than exponentially. Credit: S. Kelley/NIST Shine a flashlight into a murky … Read more
