Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of quantum computer.

Sugar-based catalyst upcycles carbon dioxide      (via sciencedaily.com)     Original source 

New catalyst is made from an inexpensive, abundant metal and table sugar. Catalyst converts carbon dioxide (CO2) into carbon monoxide, a building block for producing a variety of useful chemicals including syngas. With recent advances in carbon capture technologies, post-combustion carbon capture is becoming a plausible option to help tackle the global climate change crisis. But how to handle the captured carbon remains an open-ended question. The new catalyst potentially could provide one solution for disposing the potent greenhouse gas by converting it into a more valuable product.

New approach in the synthesis of complex natural substances      (via sciencedaily.com)     Original source 

Many natural substances possess interesting characteristics, and can form the basis of new active compounds in medicine. Terpenes, for example, are a group of substances, some of which are already used in therapies against cancer, malaria or epilepsy. They are found as fragrances in cosmetics or as flavorings in food, and form the basis of new medications: Terpenes are natural substances that occur in plants, insects and sea sponges. They are difficult to produce synthetically. However, chemists are now introducing a new method of synthesis.

Physicists build new device that is foundation for quantum computing      (via sciencedaily.com)     Original source 

Scientists have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity between a qubit, the fundamental unit of quantum computing, and a microwave-resonant cavity. The ability to precisely tune the degree of nonreciprocity is an important tool to have in quantum information processing. In doing so, the team derived a general and widely applicable theory that simplifies and expands upon older understandings of nonreciprocity so that future work on similar topics can take advantage of the team's model, even when using different components and platforms.

Researchers develop an AI model to reduce uncertainty in evapotranspiration prediction      (via sciencedaily.com)     Original source 

Evapotranspiration (ET) includes evaporation from soil and open water pools such as lakes, rivers, and ponds, as well as transpiration from plant leaves. The difference between precipitation and ET indicates the water balance available for societal needs, including agricultural and industrial production. However, measuring ET is challenging. A new study presents a computer model that uses artificial intelligence (AI) for ET prediction based on remote sensing estimates.

Scientists solve chemical mystery at the interface of biology and technology      (via sciencedaily.com)     Original source 

Organic electrochemical transistors (OECTs) allow current to flow in devices like implantable biosensors. But scientists long knew about a quirk of OECTs that no one could explain: When an OECT is switched on, there is a lag before current reaches the desired operational level. When switched off, there is no lag. Current drops immediately. Researchers report that they have discovered the reason for this activation lag, and in the process are paving the way to custom-tailored OECTs for a growing list of applications in biosensing, brain-inspired computation and beyond.

Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.
