Analog monolayer SWCNTs-based memristive 2D structure for energy-efficient deep learning in spiking neural networks
Abstract Advances in materials science and memory devices work in tandem for the evolution of Artificial Intelligence systems. Energy-efficient computation is the ultimate goal of emerging memristor technology, in which the storage and computation can be done in the same memory crossbar. In this work, an analog memristor device is fabricated utilizing the unique characteristics…

Nanofluidic qPCR unable to detect and serotype Streptococcus pneumoniae in urine samples of hospitalized South African patients with community-acquired pneumonia
Abstract Pneumonia is a major cause of death among adults living with HIV in South Africa, but the etiology of many cases remains unknown. This study evaluated the utility of a nanofluidic qPCR assay to detect and serotype Streptococcus pneumoniae in urine samples from patients hospitalized with community-acquired pneumonia (CAP). The nanofluidic qPCR assay was…

A look at the new discoveries that make Neanderthals more knowable now than ever
Neanderthals are Homo sapiens’s closest-known relative, and today we know we rubbed shoulders with them for thousands of years, up until the very end of their long reign some 40,000 years ago. Most researchers see no reason to believe our two species didn’t get along with each other back then, yet we haven’t been very…

Scams for everyone
Now that you have read in the Chieftain about the new weight reducing drugs and their high price, you might have guessed that someone, somewhere would come up with a way to provide you with a cheaper way to bring you this desirable medication. I have already seen one ad for “GLP-1 Weight management. Only…

Vague peace agreements and climate scientists’ calls to action: The 6 biggest stories from 3 December at COP28
Most world leaders have now left COP28, meaning attention is turning to the processes happening within the negotiation rooms for the final texts. Only a select handful of people are permitted to observe these official proceedings, so most of the tens of thousands of people at the Expo Centre today are here to explore the…

The Most Successful Branding Campaign Of All Time? AI
The most successful branding campaign of all time is “artificial intelligence” or AI. Invented in 1955, the brand has experienced ups and downs, over-the-top hype and near-extinction. Recently, it has re-emerged as the widely popular brand name for a successful approach to endowing computers with seemingly human-like intelligence, an approach that has nothing to do…

COP28 Report: 10 Key Climate Insights for Policymakers
Combining pivotal climate research over the last 18 months, the scientists are using the report to help inform policy implementation at COP28 and beyond. The 10 New Insights in Climate Science series have been launched at COPs since 2017, in partnership with the UNFCCC. To mark COP28, UNFCCC Executive Secretary, Simon Stiell, has worked with…

Physicists May Have Found a Hard Limit on The Performance of Large Quantum Computers
For circuit-based quantum computations, the achievable circuit complexity is limited by the quality of timekeeping. That’s according to a new analysis published in the journal Physical Review Letters exploring “the effect of imperfect timekeeping on controlled quantum dynamics.” An announcement from the Vienna University of Technology explains its significance. “The research team was able to…
