Researchers from North Carolina State University and Johns Hopkins University have demonstrated a technology capable of a suite of data storage and computing functions – repeatedly storing, retrieving, computing, erasing or rewriting data – that uses DNA rather than conventional electronics. Previous DNA data storage and computing technologies could complete some but not all of these tasks.

“In conventional computing technologies, we take for granted that the ways data are stored and the way data are processed are compatible with each other,” says project leader Albert Keung, co-corresponding author of a paper on the work (Nature Nanotechnology, “A Primordial DNA Store and Compute Engine”). “But in reality, data storage and data processing are done in separate parts of the computer, and modern computers are a network of complex technologies,” Keung is an associate professor of chemical and biomolecular engineering and a Goodnight Distinguished Scholar at NC State.

“DNA computing has been grappling with the challenge of how to store, retrieve and compute when the data is being stored in the form of nucleic acids,” Keung says. “For electronic computing, the fact that all of a device’s components are compatible is one reason those technologies are attractive. But, to date, it’s been thought that while DNA data storage may be useful for long-term data storage, it would be difficult or impossible to develop a DNA technology that encompassed the full range of operations found in traditional electronic devices: storing and moving data; the ability to read, erase, rewrite, reload or compute specific data files; and doing all of these things in programmable and repeatable ways.

Neuromorphic computing memristors are attractive to construct low-power-consumption electronic textiles. Here, authors report an ultralow-power textile memristor network of Ag/MoS2/HfAlOx/carbon nanotube with reconfigurable characteristics and firing energy consumption of 1.9 fJ/spike.

In the past decade, lab-grown blobs of human brain tissue began making news headlines, as they ushered in a new era of scientific discovery and raised a slew of ethical questions.

These blobs — scientifically known as brain organoids, but often called “minibrains” in the news — serve as miniature, simplified models of full-size human brains. These organoids can potentially be useful in basic research, drug development and even computer science.

A team of scientists in the United States has achieved a notable milestone in the domain of superconductors. This progress may have considerable consequences for the future of quantum computing.

The research details the development of a novel superconductor material that has the potential to transform quantum computing and potentially function as a “topological superconductor.”

A topological superconductor is a special kind of material that exhibits superconductivity (zero electrical resistance) and also has unique properties related to its shape or topology.

An on-chip nano-bolometer integrated with a Josephson junction quantitatively measures the Josephson radiation up to about 100 GHz frequency. This wide-band, thermal detection scheme of microwave photons provides a sensitive detector of Josephson dynamics beyond the standard conductance measurements.

Neuralink says it has successfully implanted another brain chip in a human patient.

According to a study update shared by the company, the patient, identified by his first name, Alex, has been improving his ability to play video games and has started learning how to use design software to create 3D objects.

The company said the procedure “went well,” and Alex’s recovery “has been smooth.”
