Published More than meows: How bacteria help cats communicate
(via sciencedaily.com) Original source Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study shows how domestic cats send signals to each other using odors derived from families of bacteria living in their anal glands.
Published No one-size-fits-all solution for the net-zero grid
(via sciencedaily.com) Original source As power generation from sources like solar and wind increases, along with the introduction of devices such as heat pumps and batteries, a new optimization tool will help the UK plan for a greener electricity network. The researchers developed an algorithm to model how these smaller networks distributed electricity -- factoring in how local grids could become unbalanced by adding too many heat pumps in a single area or generating more electricity than the grid could accept.
Published Preventing hydrogen vehicle aging during sudden stops
(via sciencedaily.com) Original source Engineers enhance hydrogen fuel cell durability via tungsten oxide coating.
Published How bacteria recognize viral invasion and activate immune defenses
(via sciencedaily.com) Original source Bacteria have an array of strategies to counter viral invasion, but how they first spot a stranger in their midst has long been a mystery.
Published Visualizing 'traffic jams' inside living cells
(via sciencedaily.com) Original source Researchers have unveiled a groundbreaking approach to label-free visualization of intracellular cargo trafficking in living cells, achieving high-speed and limitless observation capabilities. By developing a cargo-localization interferometric scattering (CL-iSCAT) microscope, scientists meticulously tracked the intricate movements of numerous cargos in the bustling cellular world. Surprisingly, cells employ human-like strategies to manage their transport challenges.
Published Water splitting reaction for green hydrogen gas production improved
(via sciencedaily.com) Original source Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.
Published Colliding ribosomes activate RNA repair
(via sciencedaily.com) Original source Researchers discover how ribosomes contribute to the recognition and removal of RNA crosslinking damage.
Published Novel C. diff structures are required for infection, offer new therapeutic targets
(via sciencedaily.com) Original source Newly discovered iron storage 'ferrosomes' inside the bacterium C. diff -- the leading cause of hospital-acquired infections -- are important for infection in an animal model and could offer new targets for antibacterial drugs. They also represent a rare demonstration of a membrane-bound structure inside a pathogenic bacterium, upsetting the biological dogma that bacteria do not contain organelles.
Published Shedding new light on sugars, the 'dark matter' of cellular biology
(via sciencedaily.com) Original source Chemists have developed a new tool for detecting interactions between sugars and lectins, a discovery that could help in the fight against diseases like cancer.
Published A tale of two proteins: Fundamental research could make growing better crops like clockwork
(via sciencedaily.com) Original source Rhomboid-like protein 10, or RBL10, is thought to be an enzyme that degrades other proteins in the chloroplast membrane, but its function is largely unknown. Researchers are studying how RBL10 affects photosynthetic membrane lipid metabolism, an essential process in photosynthesis.
Published Ammonia fuel offers great benefits but demands careful action
(via sciencedaily.com) Original source Researchers have identified the potential environmental risks of using ammonia as a zero-carbon fuel in order to develop an engineering roadmap to a sustainable ammonia economy.
Published New discovery on how green algae count cell divisions illuminates key step needed for the evolution of multicellular life
(via sciencedaily.com) Original source An international research team has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division.
Published Solar-powered device produces clean water and clean fuel at the same time
(via sciencedaily.com) Original source A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers.
Published New work sheds light on inner working of cells
(via sciencedaily.com) Original source New research provides a deeper understanding of the way components within cells are interconnected. Through cellular visualization using SRS microscopy, researchers have addressed the challenge of attaining clear images of individual processes.
Published Yeast cells can produce drugs for treatment of psychotic disorders
(via sciencedaily.com) Original source An international team of researchers has demonstrated that genetically engineered yeast cells can produce the natural plant product alstonine, which has shown positive effects in treating schizophrenia.
Published Team creates synthetic enzymes to unravel molecular mysteries
(via sciencedaily.com) Original source A bioengineer has developed synthetic enzymes that can control the behavior of the signaling protein Vg1, which plays a key role in the development of muscle, bone and blood in vertebrate embryos. The team of researchers is using a new approach, called the Synthetic Processing (SynPro) system, in zebrafish to study how Vg1 is formed. By learning the molecular rules of signal formation in a developing animal, researchers aim to engineer mechanisms -- such as giving cells new instructions -- that could play a role in treating or preventing disease.
Published 'Indoor solar' to power the Internet of Things
(via sciencedaily.com) Original source From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.
Published New way to count microbes speeds research, cuts waste, could lead to new antibiotics
(via sciencedaily.com) Original source Researchers have developed a new way of counting microorganisms that works as much as 36 times faster than conventional methods, cuts plastic use more than 15-fold and substantially decreases the cost and carbon footprint of biomedical research. The technique could revolutionize the way microbiology experiments are conducted, allowing researchers to test potential new antibiotics in a fraction of the time.
