Brain-based computing chips not just for AI anymore

Posted by in categories: biotech/medical, finance, mathematics, robotics/AI

With the insertion of a little math, Sandia National Laboratories researchers have shown that neuromorphic computers, which synthetically replicate the brain’s logic, can solve more complex problems than those posed by artificial intelligence and may even earn a place in high-performance computing.

The findings, detailed in a recent article in the journal Nature Electronics, show that neuromorphic simulations employing the statistical method called random walks can track X-rays passing through bone and soft tissue, disease passing through a population, information flowing through social networks and the movements of financial markets, among other uses, said Sandia theoretical neuroscientist and lead researcher James Bradley Aimone.

2023 Moon to Mars Architecture Concept Review Outcomes Released by NASA

Posted by in categories: biological, physics, space travel

NASA’s Moon to Mars Architecture has been instrumental in developing, designing, and executing the long-term goals of establishing not only a permanent human presence on the Moon but sending humans to Mars, someday. Today, NASA announced the results from the recent 2023 Moon to Mars Architecture Concept Review, which outlines key objectives, strategies, and key decisions in establishing a human presence on Mars in the future.

The Concept Review discussed in detail the architecture objectives and segments for not only returning humans to the Moon but establishing a long-term presence there through testing new technologies, systems, and equipment that would be used on an eventual human mission to Mars. the Moon to Mars Objectives cover a myriad of goals, including lunar and planetary science, heliophysics, human and biological science, physics and physical sciences, science enabling, applied science, lunar infrastructure, Mars infrastructure, transportation and habitation, and operations.

“Over the last year we’ve been able to refine our process for Moon to Mars architecture concept development to unify the agency,” Nujoud Merancy, who is the Deputy Associate Administrator for Strategy & Architecture for NASA’s Exploration Systems Development Mission Directorate (ESDMD), said in a statement. “Our process in the coming months will focus on addressing gaps in the architecture and further reviewing the decisions the agency needs to make to successfully mount crewed Mars missions.”

Scientists Coax Bacteria Into Making Exotic Proteins Not Found in Nature

Posted by in category: robotics/AI

A Whole New World

Scientists have already found hundreds of exotic amino acids. AI models such as AlphaFold or RoseTTAFold, and their variations, are likely to spawn even more. Finding carriers and “glue” proteins that match has always been a roadblock.

The new study establishes a method to speed up the search for new designer proteins with unusual properties. For now, the method can only incorporate four synthetic amino acids. But scientists are already envisioning uses for them.

The Role of Electric Aircraft in Reducing Environmental Impact

Posted by in categories: climatology, habitats, sustainability

“The key take-home from this study is that small electric aircraft can have a notably lower climate impact – up to 60 percent less – and other types of environmental impacts than equivalent fossil-fueled aircraft,” said Dr. Rickard Arvidsson.


In a time when electric cars are increasing in number around the world and contributing to a greener future, can electric aircraft do the same? This is what a recent study published in The International Journal of Life Cycle Assessment hopes to address as a team of researchers from the Chalmers Institute of Technology in Sweden investigated the environmental impact of an electric aircraft versus a fossil fuel-based counterpart. This study holds the potential to help better understand the pros and cons of electric aircraft while underscoring their environmental impact for both the short-and long-term.

For the study the researchers conducted a life cycle assessment of a “Pipistrel Alpha Electro” aircraft and a fossil fuel-based aircraft to determine which was more environmentally friendly. The Alpha Electro’s structure consisted of an approximately 10-meter (33-feet) wingspan and weighs 550 kg (1212 pounds) at full weight. It was powered by a 21 kWh NMC (nickel-manganese cobalt) lithium-ion battery, resulting in a 60 kW engine output. The fossil fuel-based aircraft was comprised of the same structure as the Alpha Electro aside from the gas engine and fuel tank. The goal of the study was to ascertain when the Alpha Electro obtains a “break-even” point with its gas-powered counterpart in terms of the overall environmental impact.

BMW previews early look at its new high-performance i5 M60 Touring EV

Posted by in category: transportation

BMW’s 5 series is set to expand very soon. The automaker is teasing the new BMW i5 M60 Touring, giving us a sneak peek at what we can expect from the high-performance EV.

After teasing an electric 5 series sedan for over six years, BMW finally unveiled the i5 last May. It’s a slightly larger, all-electric take on its predecessor. BMW included its latest software and tech, including OS 8.5.

The i5 is in the middle of the 3 series and larger 7 series in BMW’s lineup. As its second best-selling vehicle, the 5 series has and will continue to play a key role in the brand’s success.

Closing the green gap: A cubic III-nitride active layer with 32% internal quantum efficiency

Posted by in categories: futurism, quantum physics

Color mixing is the process of combining two or more colors: red and green make yellow, blue and red make purple, red and green and blue make white. This process of mixing colors is the basis for the future of solid-state lighting. While currently white light is achieved by phosphor down-conversion, LED color mixing actually has a higher theoretical maximum efficiency, which is needed in order to achieve the 2035 DOE energy efficiency goals.

Despite the potential efficiency of color-mixed LED sources, there exists one significant challenge: green. The “green gap” is described as the lack of suitable green LEDs. Current green LEDs are made from state-of-the-art hexagonal III-nitride but only reach one third of the efficiency goals laid out in the 2035 DOE roadmap.

In a new study, researchers at the University of Illinois Urbana-Champaign have found a potential path to fill the green gap and report a green-emitting cubic III-nitride active layer with 32% internal quantum efficiency (IQE), which is more than 6 times higher efficiency than what is reported in the literature for conventional cubic active layers.

Performing complex-valued linear transformations using spatially incoherent diffractive optical networks

Posted by in categories: encryption, robotics/AI

The bulk of the computing in state-of-the-art neural networks comprises linear operations, e.g., matrix-vector multiplications and convolutions. Linear operations can also play an important role in cryptography. While dedicated processors such as GPUs and TPUs are available for performing highly parallel linear operations, these devices are power-hungry, and the low bandwidth of electronics still limits their operation speed. Optics is better suited for such operations because of its inherent parallelism and large bandwidth and computation speed.

Built from a set of spatially engineered thin surfaces, diffractive deep (D2NN), also known as diffractive networks, form a recently emerging optical computing architecture capable of performing passively at the speed of light propagation through an ultra-thin volume.

These task-specific all-optical computers are designed digitally through learning of the spatial features of their constituent diffractive surfaces. Following this one-time design process, the optimized surfaces are fabricated and assembled to form the physical hardware of the diffractive optical .
