Batteries that exploit quantum phenomena to gain, distribute and store power promise to surpass the abilities and usefulness of conventional chemical batteries in certain low-power applications. For the first time, researchers, including those from the University of Tokyo, take advantage of an unintuitive quantum process that disregards the conventional notion of causality to improve the performance of so-called quantum batteries, bringing this future technology a little closer to reality.

When you hear the word “quantum,” the physics governing the subatomic world, developments in quantum computers tend to steal the headlines, but there are other upcoming quantum technologies worth paying attention to. One such item is the quantum battery which, though initially puzzling in name, holds unexplored potential for sustainable energy solutions and possible integration into future electric vehicles. Nevertheless, these new devices are poised to find use in various portable and low-power applications, especially when opportunities to recharge are scarce.

At present, quantum batteries only exist as laboratory experiments, and researchers around the world are working on the different aspects that are hoped to one day combine into a fully functioning and practical application. Graduate student Yuanbo Chen and Associate Professor Yoshihiko Hasegawa from the Department of Information and Communication Engineering at the University of Tokyo are investigating the best way to charge a quantum battery, and this is where time comes into play. One of the advantages of quantum batteries is that they should be incredibly efficient, but that hinges on the way they are charged.

They had to throw away most of what it produced but there was gold among the garbage.

Prior studies have linked high blood cholesterol levels to various cancers, including colorectal cancers. However, it hasn’t been clear that lowering cholesterol can prevent colorectal cancers. Now, researchers at Weill Cornell Medicine have found in mice hard-to-detect colorectal pre-cancerous lesions known as serrated polyps, and the aggressive tumors that develop from them, depend heavily on the ramped-up production of cholesterol. Their finding points to the possibility of using cholesterol-lowering drugs to prevent or treat such tumors.

The findings are published in Nature Communications in an article titled, “Enhanced SREBP2-driven cholesterol biosynthesis by PKCλ/ι deficiency in intestinal epithelial cells promotes aggressive serrated tumorigenesis.”

“The metabolic and signaling pathways regulating aggressive mesenchymal colorectal cancer (CRC) initiation and progression through the serrated route are largely unknown,” the researchers wrote. “Although relatively well characterized as BRAF mutant cancers, their poor response to current targeted therapy, difficult preneoplastic detection, and challenging endoscopic resection make the identification of their metabolic requirements a priority. Here, we demonstrate that the phosphorylation of SCAP by the atypical PKC (aPKC), PKCλ/ι promotes its degradation and inhibits the processing and activation of SREBP2, the master regulator of cholesterol biosynthesis.”

A University of Oxford-led study has found that diverse communities of resident commensal gut bacteria collectively protect the human gut from disease-causing microorganisms by consuming the nutrients that the pathogen would need to be able to gain a foothold in the host.

The team used an ecological approach to investigate how colonization by two major bacterial pathogens— Klebsiella pneumoniae and Salmonella enterica serovar Typhimurium (S. Typhimurium)—is influenced by a range of human gut bacteria both in vitro and in gnotobiotic mice. They found that the ecological diversity of the microbiome was important for colonization resistance. While single species of gut microbiota alone had negligible effects on providing effective resistance to pathogens, certain combinations of essential key species within diverse communities exhibited much greater colonization resistance when together.

Having found that these communities block pathogen growth by consuming nutrients that would be required by the pathogen, the team also showed that the concept of nutrient blocking can be used to predict specific sets of commensal microbiota that will resist a novel bacterial pathogen, using genome sequence data alone.

Researchers at the MRC Weatherall Institute of Molecular Medicine’s Laboratory of Gene Regulation, led by Professor Doug Higgs and Dr. Mira Kassouf, have published a study in the journal Cell, in which they reveal another piece of the puzzle of how the code in our DNA is read.

In this study, the authors introduce the concept of “facilitators,” a newly identified type of non-coding DNA that can help to drive gene expression.

All of the cells in your body contain the same DNA. However, these cells are able to develop into over 200 different types and make up a variety of different specialized tissues such as the skin, the blood, and the brain.

For the first time ever, researchers show how a large language model can help discover novel solutions to long-standing problems in math and computer science.

The card game Set has long inspired mathematicians to create interesting problems.

Now, a technique based on large language models (LLMs) is showing that artificial intelligence (AI) can help mathematicians to generate new solutions.
