[In Depth] Bendy bugs inspire roboticists

Insects, whether they creep or fly, live in a world of hard knocks. Who has not stepped on a cockroach, then raised her shoe to watch the creature get up and scoot under a door? Bees and wasps, for their part, face a never-ending obstacle course of leaves, stems, and petals—bumblebees crash their wings into […]

[Report] Using decoys to expand the recognition specificity of a plant disease resistance protein

Maintaining high crop yields in an environmentally sustainable manner requires the development of disease-resistant crop varieties. We describe a method to engineer disease resistance in plants by means of an endogenous disease resistance gene from Arabidopsis thaliana named RPS5, which encodes a nucleotide-binding leucine-rich repeat (NLR) protein. RPS5 is normally activated when a second host […]

[In Depth] Triumph for gravitational wave hunt

More than a billion years ago, two black holes—the gravitational ghosts of gigantic stars—spiraled together and collided in space. Ripples in spacetime swept through the universe. Five months ago, they washed past Earth, and physicists detected gravitational waves for the first time. The long-awaited discovery—announced this week—marks a triumph for the Laser Interferometer Gravitational-Wave Observatory […]

[Report] Broadly targeted CD8+ T cell responses restricted by major histocompatibility complex E

Major histocompatibility complex E (MHC-E) is a highly conserved, ubiquitously expressed, nonclassical MHC class Ib molecule with limited polymorphism that is primarily involved in the regulation of natural killer (NK) cells. We found that vaccinating rhesus macaques with rhesus cytomegalovirus vectors in which genes Rh157.5 and Rh157.4 are deleted results in MHC-E–restricted presentation of highly […]

How LIGO Found a Gravitational Wave in a Haystack

How LIGO Found a Gravitational Wave in a Haystack

Image: Henze/NASA3D visualization of gravitational waves produced by 2 orbiting black holes. Washington, D.C.—The wait is over. After months of rumors, the Laser Interferometer Gravitational-Wave Observatory (LIGO) today announced the first direct detection of a gravitational wave. The announcement was simple but dramatic. “Ladies and gentlemen we have detected gravitational waves. We did it,” LIGO executive director David Reitze said on […]

Supercapacitor On-a-Chip Now One Step Closer

Supercapacitor On-a-Chip Now One Step Closer

Photo: Image: CIRIMAT/Université Paul Sabatier-Toulouse III In 2010 Spectrum reported a new approach for creating chip-scale supercapacitors on silicon wafers, proposed by researchers at Drexel University in Philadelphia and the Université Paul Sabatier in Toulouse, France. In an article published in Science, the researchers described  how to make supercapacitor electrodes from porous carbon that could stick to the surface of silicon […]
