Published Scallop eyes as inspiration for new microscope objectives
(via sciencedaily.com) Original source Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.
Published AI predicts enzyme function better than leading tools
(via sciencedaily.com) Original source A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. Researchers said the AI tool, dubbed CLEAN, outperforms the leading state-of-the-art tools in accuracy, reliability and sensitivity. Better understanding of enzymes and their functions would be a boon for research in genomics, chemistry, industrial materials, medicine, pharmaceuticals and more.
Published New details of SARS-COV-2 structure
(via sciencedaily.com) Researchers used computational modeling to reveal finer details surrounding the outer shell of the COVID-19 virus. The work expands the scientific community's understanding of SARS-COV-2, and could lead to more refined antiviral therapies and better vaccines.
Published Charming experiment finds gluon mass in the proton
(via sciencedaily.com) Original source Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the strong force as it glues together the proton's building block quarks.
Published Mimicking biological enzymes may be key to hydrogen fuel production
(via sciencedaily.com) An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led chemists to design a synthetic molecule that mimics the hydrogen gas-producing chemical reaction performed by the enzyme.
Published Can a solid be a superfluid? Engineering a novel supersolid state from layered 2D materials
(via sciencedaily.com) Original source Physicists predict that layered electronic 2D semiconductors can host a curious quantum phase of matter called the supersolid. This counterintuitive quantum material simultaneously forms a rigid crystal, and yet at the same time allows particles to flow without friction, with all the particles belong to the same single quantum state.
Published Magnon-based computation could signal computing paradigm shift
(via sciencedaily.com) Original source Thanks to a breakthrough in the field of magnonics, researchers have sent and stored data using charge-free magnetic waves, rather than traditional electron flows. The discovery could solve the dilemma of energy-hungry computing technology in the age of big data.
Published Fermented coffee's fruity aromas demystified
(via sciencedaily.com) Fermented coffee could bring a fruity taste to your morning cup of joe. This new kind of beverage has a raspberry-like taste and aroma, but what causes these sensations has been a mystery. Scientists now report six compounds that contribute to the fermented coffee experience.
Published Surgical sealing made better with robust thermosensitive bioadhesives
(via sciencedaily.com) Original source Scientists have employed inventive chemistry to produce an injectable biomaterial with significantly improved adhesive strength, stretchability, and toughness. This chemically modified, gelatin-based hydrogel had attractive features, including rapid gelation at room temperature and tunable levels of adhesion. This custom-engineered biomaterial is ideal as a surgical wound sealant, with its controllable adhesion and injectability and its superior adherence to a variety of tissue and organ surfaces.
Published Revolutionary battery technology to boost EV range 10-fold or more
(via sciencedaily.com) A team develops layering-charged, polymer-based stable high-capacity anode material.
Published Phthalate alternative may harm brain development and health
(via sciencedaily.com) Growing concerns over the potential health effects of exposure to phthalates have led to a search for safer alternatives. Researchers found that the chemical acetyl tributyl citrate (ATBC) might not be the best replacement.
Published Team uses natural catalysts to develop low-cost way of producing green hydrogen
(via sciencedaily.com) Researchers have developed a practical way to produce green hydrogen using sustainable catalysts and say their work is a major step towards production simpler, more affordable and more scalable.
Published Biomolecules: Trying nanometer measurement for size
(via sciencedaily.com) Original source As part of a comparative international study, researchers have successfully tested and validated a method of investigating dynamic protein structures.
Published Preschoolers prefer to learn from a competent robot than an incompetent human
(via sciencedaily.com) Researchers found that preschoolers prefer learning from what they perceive as a competent robot over an incompetent human. This study is the first to use both a human speaker and a robot to see if children deem social affiliation and similarity more important than competency when choosing which source to trust and learn from.
Published Prepare for landing: Making airports more efficient
(via sciencedaily.com) Original source A team of scientists presents an original oscillating short-term memory model to study the dynamics of landing events at 10 major European airports. The model can estimate how landing volumes will influence those in consecutive hours -- a critical ability given airport capacity constraints and external events that cause landing delays. Altogether, the model demonstrates that statistical analyses of hourly plane landing volumes can yield valuable insights into airport operations.
Published The powerhouse of the future: Artificial cells
(via sciencedaily.com) Researchers identify the most promising advancements and greatest challenges of artificial mitochondria and chloroplasts. The team describes the components required to construct synthetic mitochondria and chloroplasts and identifies proteins as the most important aspects for molecular rotary machinery, proton transport, and ATP production. The authors believe it is important to create artificial cells with biologically realistic energy-generation methods that mimic natural processes; replicating the entire cell could lead to future biomaterials.
Published Team designs molecule to disrupt SARS-CoV-2 infection
(via sciencedaily.com) A team of scientists designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.
Published Advanced electrode to help remediation of stubborn new 'forever chemicals'
(via sciencedaily.com) As new environmental regulations are rolling out to mitigate the industry-retired long-chain chemicals known as PFAS in drinking water, there are concerns regarding a new breed of 'forever chemicals' called short-chain PFAS. Research is now helping shift the focus to include mitigation of the chemicals -- which researchers say are just as persistent as, more mobile and harder to remove from the environment than their long-chain counterparts.
Published Nanophysics: The right twist
(via sciencedaily.com) Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
