Researchers at Princeton’s Department of Chemistry discovered the first known de novo protein that catalyzes, or drives, the synthesis of quantum dots.

Nature uses 20 canonical amino acids.

<div class=””> <div class=””><br />Amino acids are a set of organic compounds used to build proteins. There are about 500 naturally occurring known amino acids, though only 20 appear in the genetic code. Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active. The amino acid sequences of proteins are encoded in the genes. Nine proteinogenic amino acids are called “essential” for humans because they cannot be produced from other compounds by the human body and so must be taken in as food.<br /></div> </div>

Over the past few decades, the performance of machine learning models on various real-world tasks has improved significantly. Training and implementing most of these models, however, still requires vast amounts of energy and computational power.

Engineers worldwide have thus been trying to develop alternative hardware solutions that can run artificial intelligence models more efficiently, as this could promote their widespread use and increase their sustainability. Some of these solutions are based on memristors, memory devices that can store information without consuming .

Researchers at Université Paris-Saclay-CNRS, Université Grenoble-Alpes-CEA-LETI, HawAI.tech, Sorbonne Université, and Aix-Marseille Université-CNRS have recently created a so-called Bayesian machine (i.e., an AI approach that performs computations based on Bayes’ theorem), using memristors. Their proposed system, introduced in a paper published in Nature Electronics, was found to be significantly more energy-efficient than currently employed hardware solutions.

LIGHTNING super-resolution detection concept and TauSense technology facilitate better cryogenic fluorescence imaging for advanced cryo-correlative workflows. The quality of fluorescence microscope images that guide cryo-FIB milling determines the result of the prepared lamella. Here, it is described how image quality is significantly improved by LIGHTNING and how different structures can be discerned using their fluorescence lifetime-based information.

Newspaper headlines from the U.S. to the U.K. and most places in between highlight the surge in sick patients suffering from respiratory viruses. The so-called “tripledemic” of lung infections including respiratory synclinal virus (RSV), influenza (flu) and COVID-19 (coronavirus) is likely to last throughout the winter season. This explosion of infections requires more treatment options to support overloaded hospitals and overworked medics as they restore people’s health.

It has been known for a long time that intubation of an infant with any , or even an adult with severe COVID-19 using either ventilation or extra-corporeal membrane oxygenation (ECMO), comes with risks and that could cause permanent damage not limited to the lungs. However, hypoxia, which means , is a that is a common complication of severe . If not treated, it can lead to severe disability and even death.

Cyclists are supposed to wear helmets to protect them from any untoward accidents while riding through the city on their bicycles. While the helmet can protect from serious brain injury, other parts of the body can be exposed to both minor and serious injuries in case they encounter other vehicles and even pedestrians. It would be nice if there’s a sort of airbag that can shield them from injuries in case an accident happens and that said airbag will be portable enough for them to carry around.

Researchers in Brazil have achieved a quantum breakthrough by succeeding in the creation of a source of illumination that produces two separate entangled beams of light, according to new research.

The achievement was announced by a team of physicists with Brazil’s Laboratory for Coherent Manipulation of Atoms and Light (LMCAL), located at the University of São Paulo’s Physics Institute.

Quantum entanglement is among the most perplexing phenomena observed in modern physics. It involves particles that are linked in such a way that when changes affect the quantum state of one, the other to which it is “entangled” will also be affected. Strangely, such effects even occur over significant distances, a phenomenon first described as “spooky action at a distance” after its discussion in a landmark 1935 paper by Albert Einstein, Boris Podolsky, and Nathan Rosen.
