Generative AIs are highly energy consuming systems, and their energy demand threatens their development. To address this issue, IBM recently created an energy-efficient 14 nm analog chip, which can be used to power smart phones and other electronic devices. Other alternative technologies such as brain-inspired computing and photonic computing are also being studied as potential sustainable solutions for powering the future of AI.

Researchers from UC Berkeley and UCSF have made a breakthough in brain-computer interface technology, enabling a person with paralysis to speak through a digital avatar. The system takes electrical signals from the brain and produces both speech and facial expressions. With the help of A.I. algorithms, the system is accurate and three times faster than commercially available technology.

Dr. Norte is making nanochip sails that can be propelled to 20% the speed of light propelled by a 100 Gigawatt laser array. The Starshot Breakthrough Initiative is making this possible through AI and simulation techniques to make these sails larger and at cheaper costs. The sails also have the potential to send nanochips to planets very quickly such as Mars in 32 hours, Saturn in 11 days, and Neptune in 70 days.

Biomedical engineers at the University of Sydney, in collaboration with scientists at the University of Cambridge and Harvard University, have developed sophisticated optical techniques to closely monitor the transition of proteins from liquid to solid phase and are now able to observe the process of protein aggregates forming, which is linked to the development of neurogenerative diseases. This window into the phase transition has also revealed that the internal structures of these protein agglomerates are heterogenous, where previously they were thought to be homogeneous.

This article looks at the challenges of consenting a BCI therapy trial, particularly for patients who have limited or no communication ability. It looks at the different methods that have been suggested, and how the RSV vaccine and new treatment for spinal cord injuries are making positive changes in the field.

Google-owned Waymo and General Motors-owned Cruise received an authorization to expand their operation in San Francisco, including allowing for Waymo to charge for driverless rides. Of the commissioners, 3 voted 'yes' and 1 voted 'no'. Safer Roads for All is financial backed by Waymo and the Autonomous Vehicle Industry Association. There have been dozens of incidents this year where the self driving cars nearly crashed into personnel, obstructed travel or blocked stations. Public and the City will be closely monitoring the rollout.

AI-generated designer proteins of shapes unknown to the biological universe can be created from scratch in order to expand the biological universe and create new weapons against viral infections and other diseases. AlphaFold and RoseTTAFold from DeepMind and the David Baker lab are two AI models that can accurately predict protein structures based on amino acid sequences. This opens up a range of potential applications in drug delivery and nanostructures.

SpaceX is preparing for its second test flight of its fully-integrated Starship launch system. This system contains two separate elements - Super Heavy and the 165-foot-tall (50-meter) Starship upper stage prototype - which has been designed to be fully reusable. SpaceX has made modifications to Booster 9 to enable hot-staging separation shortly after launch, and it has also conducted static fire engine tests at its South Texas test site to evaluate the system's performance during launch.

When disasters strike, people often take their pets with them if possible. However, cats might be skittish and even with the best intentions, pets can become lost, injured or even killed. Islands present unique challenges due to limited resources. Aid for animals is ultimately important as people often suffer psychological distress from losing their pets, and they may even refuse to evacuate if they cannot bring their pets.

A team of researchers from Texas A&M University and four other institutions created malicious software called EarSpy which used machine learning algorithms to filter a surprising amount of caller information from ear speaker vibration data recorded by Android smartphones. The EarSpy malware was able to determine the gender and identity of the caller with 91.6% accuracy and recognize spoken digits with 56% accuracy. Previous research indicated iPhones were less vulnerable to caller identity detection.

The National Museum of Denmark is currently home to a clay brick from the palace of the Neo-Assyrian king Ashurnasirpal II. An interdisciplinary team was able to extract DNA from the brick and identify 34 distinct taxonomic groups of plants. The research serves as a proof of concept and method that can be applied to other archaeological sources of clay around the world, to identify past flora and fauna.

Our research into the biological root of arithmetic has led us to believe mathematics is a realization in symbols of the fundamental nature and creativity of the mind. We explored the behavior of bees to gain insight into this, as they can take a meandering journey to find nectar and then return by the most direct route. We showed that the abilities of bees in returning to the hive suggested principles that could be used to explain simpler arithmetic operations. Our study brings together the insights from the psychologist Jean Piaget and the mathematician Jacques Hadamard.

Whale expert Olga Filatova from the University of Southern Denmark has dedicated her research to unraveling the mysteries of orca colonization in the northern Pacific. She has now found two refugiums from the ice age – near the Aleutian Islands and in northern Japan – where orcas have stayed since the last ice age, some 20,000 years ago. This is based on genetic analysis and the vocal repertoire of the whales being studied. These orcas are highly diverse in genetics and sound, and don't interact with one another.

University of Waterloo researchers have developed a new explainable artificial intelligence (XAI) model, called Pattern Discovery and Disentanglement (PDD), which aims to reduce bias and enhance trust and accuracy in machine learning-generated decision-making and knowledge organization. This new model has the ability to identify unknown factors that could be biasing machine learning results, as well as customize decision-making for different medical settings and patient populations. The model was developed as a result of analyzing protein binding data from X-ray crystallography, and it has the potential to revolutionize decision-making in the medical field.

Tropical storms in the Southwest are rare occurrences, with only one confirmed landfall in the last 82 years. However, remnant storms from tropical cyclones are fairly common in the region, with an average of 3.1 affecting the U.S. Southwest each year from 1992 to 2005. These storms continue on after a tropical cyclone loses its surface circulation. Factors making this storm unusual are an El Niño climate pattern and a heat dome over much of the U.S, pushing winds east and south and allowing storms to come way farther north than they normally would.

Recent application of AI algorithms to image-enhancement tools have enabled researchers to cope with limits to how much data can be retrieved from any image. Tomer Michaeli’s Perception-Distortion Trade-Off (in 2017) plotted the performance of various image-enhancement algorithms on a graph of distortion versus perceptual quality to produce the best image quality for a given level of distortion. In 2017, Nvidia researchers developed an image-enhancement algorithm that went beyond the perception-distortion trade-off, blurring it in areas where that was beneficial.

The US government has an immensely complex system for managing radio frequencies for US airwaves and publishes the United States Frequency Allocation Chart for visibility. US government controls a large portion of the radio spectrum and grants licenses to amateur radio operators, businesses, and other institutions to ensure its safety and efficiency. This chart uses 33 color-coded categories and is due for another revision since it was last updated in 2016.
