RISC-V errors Princeton University researchers have discovered a series of errors in the RISC-V instruction specification that now are leading to changes in the new system, which seeks to facilitate open-source design for computer chips. In testing a technique they created for analyzing computer memory use, the team found over 100 errors involving incorrect orderings in the storage and retr... » read more

Printable circuits with silver nanowires Scientists at Duke University compared the conductivity of films made from different shapes of silver nanostructures and found that electrons move through films made of silver nanowires much easier than films made from other shapes, like nanospheres or microflakes. In fact, electrons flowed so easily through the nanowire films that they could function... » read more

Scalable data center chip Princeton University researchers designed a new scalable chip specifically for data centers and massive computing systems. The team believes the chip, called Piton, can substantially increase processing speed while slashing energy needs. The chip architecture is scalable; designs can be built that go from a dozen cores to several thousand. Also, the architecture ... » read more

A foggy consortium Scientists at Princeton University, ARM, Cisco, Dell, Intel, and Microsoft formed a global effort to develop architectures and tools to further "fog computing" and networks, which aim to harness connected devices' own computing, sensing and storage power to form edge networks that meet most of the demand of user devices that are at the periphery of a more centralized netwo... » read more

Extracting the right information in large data sets When solving complex scientific problems, researchers sometimes encounter what is called the curse of dimensionality, that is, they have so much data that they cannot efficiently analyze it. Large data sets can also be expensive and time consuming to acquire, so it is critical to gather only what is necessary. To this end, University of Il... » read more

Massless particles for faster electronics Princeton University researchers along with an international team have finally proved a massless particle that had been theorized for 85 years. They say this particle could give rise to faster and more efficient electronics because of its unusual ability to behave as matter and antimatter inside a crystal.

Observing antiferromagnetic order in ultracold atoms Rice University researchers have simulated superconducting materials and made headway on a problem that’s vexed physicists for nearly three decades using ultracold atoms as a stand-in for electrons. The research team, led by Rice, included researchers from Ohio State University, Universidade Federal do Rio de Janeiro, University of Cal... » read more

Turning loss to gain By reexamining longstanding beliefs about the physics of lasers, Princeton University engineers have shown that by carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude. The team believes this finding could enable more sensitive and energy-efficient lasers, as well as potentially more control over ... » read more
