High-accuracy electric vehicle battery monitoring with diamond quantum sensors for driving range extension      (via sciencedaily.com) 

The issue of battery usage inefficiency in electric vehicles resulting from an inaccurate battery charge measurement may finally get resolved, thanks to a diamond quantum sensor prototype. The sensor can measure currents in a wide range as well as detect milliampere-level currents in a noisy environment, improving the detection accuracy from 10% to within 1%.

Martian rock-metal composite shows potential of 3D printing on Mars      (via sciencedaily.com) 

A small amount of simulated crushed Martian rock mixed with a titanium alloy made a stronger, high-performance material in a 3D-printing process that could one day be used on Mars to make tools or rocket parts. The parts were made by researchers with as little as 5% up to 100% Martian regolith, a black powdery substance meant to mimic the rocky, inorganic material found on the surface of the red planet. While the parts with 5% Martian regolith were strong, the 100% regolith parts proved brittle and cracked easily. Still, even high-Martian content materials would be useful in making coatings to protect equipment from rust or radiation damage.

Making nanodiamonds out of bottle plastic      (via sciencedaily.com) 

What goes on inside planets like Neptune and Uranus? To find out, an international team conducted a novel experiment. They fired a laser at a thin film of simple PET plastic and investigated what happened using intensive laser flashes. One result was that the researchers were able to confirm their earlier thesis that it really does rain diamonds inside the ice giants at the periphery of our solar system. And another was that this method could establish a new way of producing nanodiamonds, which are needed, for example, for highly-sensitive quantum sensors.

Research unlocks secrets of rodents' rat race to new lands      (via sciencedaily.com) 

New research has mapped the DNA from more than 150 species of native rodents from across Australia, New Guinea and Melanesian islands, painting a clearer picture of how they're related and how they ended up spreading across the Pacific.

Did primitive cetaceans feed like marine reptiles?      (via sciencedaily.com) 

Did the first ancestors of whales pick up where the mosasaurs left off 66 million years ago, after the extinction of all the large predatory marine reptiles? A study has looked into the possible convergences in morphology and behavior that may exist between these two groups of large marine predatory animals.

New method to systematically find optimal quantum operation sequences for quantum computers developed      (via sciencedaily.com) 

Computer scientists have succeeded in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer. They have developed a systematic method that applies optimal control theory (GRAPE algorithm) to identify the theoretically optimal sequence from among all conceivable quantum operation sequences. This method is expected to become a useful tool for medium-scale quantum computers and is expected to contribute to improving the performance of quantum computers and reducing environmental impact in the near future.

NASA's Webb takes its first-ever direct image of distant world      (via sciencedaily.com) 

Astronomers have used NASA's James Webb Space Telescope to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable. The image shows how Webb's powerful infrared gaze can easily capture worlds beyond our solar system, pointing the way to future observations that will reveal more information than ever before about exoplanets.

Astronomers show how terrain evolves on icy comets      (via sciencedaily.com)     Original source 

With an eye toward a possible return mission years in the future, Cornell University astronomers have shown how smooth terrains -- a good place to land a spacecraft and to scoop up samples -- evolve on the icy world of comets.

Global analysis identifies at-risk forests      (via sciencedaily.com) 

Researchers quantify the risk to forests from climate change along three dimensions: carbon storage, biodiversity and forest loss from disturbance, such as fire or drought. The results show forests in some regions experiencing clear and consistent risks. In other regions, the risk profile is less clear, because different approaches that account for disparate aspects of climate risk yield diverging answers.

The impact of megafires on estuaries from Australia's 'Black Summer'      (via sciencedaily.com) 

Estuaries are one of the most valuable biomes on Earth, and megafires -- like Australia's 2019/20 Black Summer fires -- represent an emerging threat to estuarine and coastal ecosystems, with the extent and proximity of the wildfire influencing the impact on estuaries.

A sustainable battery with a biodegradable electrolyte made from crab shells      (via sciencedaily.com) 

Accelerating demand for renewable energy and electric vehicles is sparking a high demand for the batteries that store generated energy and power engines. But the batteries behind these sustainability solutions aren't always sustainable themselves. Scientists have now create a zinc battery with a biodegradable electrolyte from an unexpected source -- crab shells.

Less risk, less costs: Portable spectroscopy devices could soon become real      (via sciencedaily.com) 

Nuclear magnetic resonance (NMR) is an analytical tool with a wide range of applications, including the magnetic resonance imaging that is used for diagnostic purposes in medicine. However, NMR often requires powerful magnetic fields to be generated, which limits the scope of its use. Researchers have now discovered potential new ways to reduce the size of the corresponding devices and also the possible associated risk by eliminating the need for strong magnetic fields. This is achieved by combining so-called zero- to ultralow-field NMR with a special hyperpolarization technique.
