Published Researchers demonstrate that quantum entanglement and topology are inextricably linked
(via sciencedaily.com) Original source Researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties.
Published Smart skin bacteria are able to secrete and produce molecules to treat acne
(via sciencedaily.com) Original source An experimental study has shown that a type of skin bacterium can efficiently be engineered to produce a protein to regulate sebum production. This application could treat acne without compromising the homeostasis of the entire skin microbiome.
Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com) Original source A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published Large-scale mapping of pig genes could pave the way for new human medicines
(via sciencedaily.com) Original source Researchers have carried out complex genetic analyses of hundreds of pigs and humans to identify differences and similarities. This new knowledge can be used to ensure healthier pigs for farmers and can help the pharmaceutical industry breed better laboratory pigs for testing new medicines.
Published Life span increases in mice when specific brain cells are activated
(via sciencedaily.com) Original source A new study identifies, in mice, a critical communication pathway connecting the brain and the body's fat tissue in a feedback loop that appears central to energy production throughout the body. The research suggests that the gradual deterioration of this feedback loop contributes to the increasing health problems that are typical of natural aging.
Published Researchers discover molecular 'barcode' used by bacteria to secrete toxins
(via sciencedaily.com) Original source Researchers have discovered a molecular 'barcode' system used by disease-causing bacteria to distinguish between beneficial and toxic molecules.
Published Important membrane transport mechanism in pathogenic bacteria
(via sciencedaily.com) Original source Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside the bacterium transports the substance to the 'elevator' and unloads its cargo there. The freight elevator transports it to the inside of the cell, in other words to another floor.
Published New roles for autophagy genes in cellular waste management and aging
(via sciencedaily.com) Original source Autophagy, which declines with age, may hold more mysteries than researchers previously suspected. Scientists have now uncovered possible novel functions for various autophagy genes, which may control different forms of disposal including misfolded proteins -- and ultimately affect aging.
Published The surprisingly resourceful ways bacteria thrive in the human gut
(via sciencedaily.com) Original source New research shows that some groups of bacteria in the gut are amazingly resourceful, with a large repertoire of genes that help them generate energy for themselves and potentially influence human health as well.
Published Scientists solve mystery of how predatory bacteria recognizes prey
(via sciencedaily.com) Original source A decades-old mystery of how natural antimicrobial predatory bacteria are able to recognize and kill other bacteria may have been solved, according to new research.
Published Nematode proteins shed light on infertility
(via sciencedaily.com) Original source Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide chromosomal interactions, and pinpointed the location where they interact with each other. Their novel method uses a technique known as genetic suppressor screening, which can serve as a blueprint for research on large cellular assemblies that resist traditional structural analysis.
Published Study reveals clues to how Eastern equine encephalitis virus invades brain cells
(via sciencedaily.com) Original source Researchers have determined how Eastern equine encephalitis virus attaches to a receptor it uses to enter and infect cells. The findings laid the groundwork for a receptor decoy molecule that protects mice from encephalitis caused by the virus.
Published Functional semiconductor made from graphene
(via sciencedaily.com) Original source Researchers have created the first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. The breakthrough throws open the door to a new way of doing electronics.
Published Bacteria load their syringes
(via sciencedaily.com) Original source Many bacterial pathogens use small injection apparatuses to manipulate the cells of their hosts, such as humans, so that they can spread throughout the body. To do this, they need to fill their syringes with the relevant injection agent. A technique that tracks the individual movement of proteins revealed how bacteria accomplish this challenging task.
Published New reasons eating less fat should be one of your resolutions
(via sciencedaily.com) Original source A new study to motivate your New Year's resolutions: it demonstrates that high-fat diets negatively impact genes linked not only to obesity, colon cancer and irritable bowels, but also to the immune system and brain function.
Published Researchers boost signal amplification in perovskite nanosheets
(via sciencedaily.com) Original source Perovskite nanosheets show distinctive characteristics with significant applications in science and technology. In a recent study, researchers achieved enhanced signal amplification in CsPbBr3 perovskite nanosheets with a unique waveguide pattern, which enhanced both gain and thermal stability. These advancements carry wide-ranging implications for laser, sensor, and solar cell applications, and can potentially influence areas like environmental monitoring, industrial processes, and healthcare.
Published Non-toxic quantum dots pave the way towards CMOS shortwave infrared image sensors for consumer electronics
(via sciencedaily.com) Original source Researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. They report on a new method for synthesizing functional high-quality non-toxic colloidal quantum dots integrable with complementary metal-oxide-semiconductor (CMOS) technology.
Published Elusive cytonemes guide neural development, provide signaling 'express route'
(via sciencedaily.com) Original source Discover the first images of cytonemes during mammalian neural development, serving as express routes to establish morphogen gradients and tissue patterning.
Published First step towards synthetic CO2 fixation in living cells
(via sciencedaily.com) Original source Three modules forming a new-to-nature CO2 fixation cycle have been successfully implemented in E.coli.
Published Big impacts from small changes in cell
(via sciencedaily.com) Original source Tiny things matter -- for instance, one amino acid can completely alter the architecture of the cell. Researchers have now investigated the structure and mechanics of the main component of the cytoskeleton of the cell: a protein known as actin. Actin is found in all living cells where it has a range of important functions -- from muscle contraction to cell signalling and cell shape. This protein comes in two different varieties termed 'isoforms', which are known as gamma actin and beta actin.
