NASA — National Aeronautics and Space Administration has tapped SiFive and Microchip Technology Inc. to create a space-centric RISC-V processor: the High-Performance Spaceflight Computing chip. At heart of the HPSC will be SiFive’s X280 64-bit RISC-V cores, which include ML acceleration capabilities.
Designed to replace existing systems still using a processor design from 1997, the RISC-V-powered chip will offer 100 times the performance.
Several antiviral drugs kill viruses by inducing lots of mutations, but a computer model suggests this could have unpredictable consequences.

According to recent research, the protein CHIP can control the insulin receptor more effectively while acting alone than when in a paired state. In cellular stress situations, CHIP often appears as a homodimer – an association of two identical proteins – and mainly functions to destroy misfolded and defective proteins. CHIP thus cleanses the cell. In order to do this, CHIP works with helper proteins to bind a chain of the small protein ubiquitin to misfolded proteins.
As a result, the cell detects and gets rid of defective proteins. Furthermore, CHIP controls insulin receptor signal transduction. CHIP binds to the receptor and degrades it, preventing the activation of life-extending gene products.
Researchers from the University of Cologne have now shown via tests using human cells and the nematode Caenorhabditis elegans that CHIP can also label itself with ubiquitin, preventing the formation of its dimer. The CHIP monomer regulates insulin signaling more effectively than the CHIP dimer. The research was conducted by the University of Cologne’s Cluster of Excellence for Cellular Stress Responses in Aging-Associated Diseases (CECAD) and was recently published in the journal Molecular Cell.

In the 80s, “with no knowledge, only intuition”, I discovered the world of computing. I believed computers could do everything, as if it were an electronic God. But when I asked the TIMEX Sinclair 1000 to draw the planet Saturn — I am fascinated by this planet, maybe because it has rings —, I only glimpse a strange message on the black and white TV:

The company’s engineers said that the new device may not be slated for use with any of the current IBM Quantum processors but that building it taught them important lessons on how to overcome these challenges.
Sumner Norman, chief neuroscientist at AE Studio, talks to Tami Freeman about the company’s work in brain–computer interfaces.
In this video I discuss 5 Types of Compute which can replace our traditional Computers in the Future.

A household microwave oven modified by a Cornell engineering professor is helping to cook up the next generation of cellphones, computers and other electronics after the invention was shown to overcome a major challenge faced by the semiconductor industry.
The research is detailed in a paper published in Applied Physics Letters. The lead author is James Hwang, a research professor in the department of materials science and engineering.
As microchips continue to shrink, silicon must be doped, or mixed, with higher concentrations of phosphorus to produce the desired current. Semiconductor manufacturers are now approaching a critical limit in which heating the highly doped materials using traditional methods no longer produces consistently functional semiconductors.

Skin-like electronics could seamlessly integrate with the body for applications in health monitoring, medication therapy, implantable medical devices, and biological studies.
With the help of the Polsky Center for Entrepreneurship and Innovation, Sihong Wang, an assistant professor of molecular engineering at the University of Chicago’s Pritzker School of Molecular Engineering, has secured patents for the building blocks of these novel devices.
Drawing on innovation in the fields of semiconductor physics, solid mechanics, and energy sciences, this work includes the creation of stretchable polymer semiconductors and transistor arrays, which provide exceptional electrical performance, high semiconducting properties, and mechanical stretchability. Additionally, Wang has developed triboelectric nanogenerators as a new technology for harvesting energy from a user’s motion—and designed the associated energy storage process.
