University of Pennsylvania engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.

The silicon-photonic (SiPh) chip’s design is the first to bring together Benjamin Franklin Medal Laureate and H...

Using the European Southern Observatory’s (ESO) Very Large Telescope (VLT), astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind but also the most luminous object ever observed...

Webb telescope observes potentially young Methane deposits on surfaces of Eris, Makemake. A team co-led by Southwest Research Institute found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or even hot geochemistry in their rocky cores, which is markedly different than the signature of methane from a comet.

“We see some interesting signs of hot times in cool places,” said SwRI’s Dr. Christopher Glein, an expert in planetary geochemistry and lead author of a paper about this discovery.

The Kuiper Belt is a vast donut-shaped region of icy bodies beyond the orbit of Neptune at the edge of the solar syste...

Researchers can engineer cells to express new genes and produce specific proteins, giving the cells new parts to work with. But, it’s much harder to provide cells with instructions on how to organize and use those new parts. Now, new tools from University of Wisconsin–Madison researchers offer an innovative way around this problem.

Their research is published in the journal Cell.

Everything a cell does depends on how molecules are organized within the cell...
