Published Cat-ching criminals with DNA from pet hairs
(via sciencedaily.com) Original source Cat hair could be the purr-fect way to catch criminals, according to researchers.
Published Intestinal bacteria metabolite promotes capture of antigens by dendritic cells
(via sciencedaily.com) Original source Dendritic cells are immune cells that capture and present antigens to T cells, activating an immune response. Researchers have discovered that short-chain fatty acids produced by intestinal bacteria regulate a crucial step in this process, the extension of dendritic 'arms.' This breakthrough finding could potentially lead to the development of disease prevention strategies involving beneficial bacteria and new drugs targeting the regulation of dendritic cell function.
Published Controlling organoids with light
(via sciencedaily.com) Original source Organoids help researchers understand biological processes in health and in disease. It is, however, difficult to influence the way in which they organize themselves into complex tissues. Now a group has found a new way to do so.
Published Protein root discovery seals future of climate-proof plants
(via sciencedaily.com) Original source Researchers have discovered a protein that seals plant roots to regulate the uptake of nutrients and water from the soil, the discovery could help develop climate proof crops that require less water and chemical fertilizers.
Published Researchers solve protein mystery
(via sciencedaily.com) Original source Researchers have uncovered that proteins use a common chemical label as a shield to protect them from degradation, which in turn affects motility and aging.
Published Genetic methods enable the use of fossil lipids as biomarkers for oxygen-producing primordial bacteria
(via sciencedaily.com) Original source Cyanobacteria are a key species in Earth's history, as they introduced atmospheric oxygen for the first time. The analysis of their evolution therefore provides important insights into the formation of modern aerobic ecosystems. For a long time, a certain type of fossil lipid, so-called 2-methylhopanes, was considered to be an important biomarker for Cyanobacteria in sediments, some of which are hundreds of millions of years old. However, this came into doubt when it turned out that not only Cyanobacteria but also Alphaproteobacteria are genetically capable of producing these lipids.
Published Controlling waves in magnets with superconductors for the first time
(via sciencedaily.com) Original source Quantum physicists have shown that it's possible to control and manipulate spin waves on a chip using superconductors for the first time. These tiny waves in magnets may offer an alternative to electronics in the future, interesting for energy-efficient information technology or connecting pieces in a quantum computer, for example. The breakthrough primarily gives physicists new insight into the interaction between magnets and superconductors.
Published Mammalian cells may consume bacteria-killing viruses to promote cellular health
(via sciencedaily.com) Original source Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival.
Published Major milestone achieved in new quantum computing architecture
(via sciencedaily.com) Original source Researchers report a significant advance in quantum computing. They have prolonged the coherence time of their single-electron qubit to an impressive 0.1 milliseconds, nearly a thousand-fold improvement.
Published Is red meat intake linked to inflammation?
(via sciencedaily.com) Original source The researchers used blood metabolite data, which can provide a more direct link between diet and health, to assess the role of red meat on inflammation risk.
Published New quantum effect demonstrated for the first time: Spinaron, a rugby in a ball pit
(via sciencedaily.com) Original source Experimental physicists have demonstrated a new quantum effect aptly named the 'spinaron.' In a meticulously controlled environment and using an advanced set of instruments, they managed to prove the unusual state a cobalt atom assumes on a copper surface. This revelation challenges the long-held Kondo effect -- a theoretical concept developed in the 1960s, and which has been considered the standard model for the interaction of magnetic materials with metals since the 1980s.
Published Cutting-edge imaging sheds new light on cells that break down bone
(via sciencedaily.com) Original source Imaging technology shows that bone-resorbing osteoclasts gather in distinct pockets, leading to new insights for osteoporosis and cancer treatment.
Published Discovery of three novel minorisa species, the smallest predatory marine picoplankton
(via sciencedaily.com) Original source Researchers have made a significant discovery by identifying and characterizing three novel species within the Minorisa genus of marine picoplankton. Before this study, only one species of Minorisa was recognized. This finding reveals previously unseen diversity of Minorisa, thereby enhancing species identification and our understanding of its ecological functions in marine ecosystems.
Published Membrane transporter ensures mobility of sperm cells
(via sciencedaily.com) Original source Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.
Published Algae's surprising potential to help ease climate change worries
(via sciencedaily.com) Original source The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.
Published Using sound to test devices, control qubits
(via sciencedaily.com) Original source Researchers have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. What's more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.
Published Defect in fruit fly respiratory system may provide insights into human aortic aneurysms
(via sciencedaily.com) Original source A team of researchers has gained new insights into the respiratory system of fruit flies -- the so-called tracheal system -- which could be important for future research into aneurysms. Scientists carried out genetic, cell biological and biochemical studies on Drosophila embryos. They found that the cells in the fruit fly's tracheal system are connected to the extracellular matrix by the proteins Dumpy and Piopio.
Published Sunflower extract fights fungi to keep blueberries fresh
(via sciencedaily.com) Original source Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it's no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against post-harvest diseases.
Published How eggs of the Zika-carrying mosquito survive desiccation
(via sciencedaily.com) Original source Eggs of the mosquito that carries Zika virus can tolerate extended desiccation by altering their metabolism, according to a new study. The finding offers potential new ways to control the spread of this mosquito.
