Published A novel method for easy and quick fabrication of biomimetic robots with life-like movement
(via sciencedaily.com) Original source Ultraviolet-laser processing is a promising technique for developing intricate microstructures, enabling complex alignment of muscle cells, required for building life-like biohybrid actuators. Compared to traditional complex methods, this innovative technique enables easy and quick fabrication of microstructures with intricate patterns for achieving different muscle cell arrangements, paving the way for biohybrid actuators capable of complex, flexible movements.
Published Predatory fish use rapid color changes to coordinate attacks
(via sciencedaily.com) Original source Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study helps to explain how they might coordinate this turn-taking style of attack on their prey to avoid injuring each other. The key, according to the new work, is rapid color changes.
Published Common plant could help reduce food insecurity
(via sciencedaily.com) Original source An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air -- making it a valuable green fertilizer -- and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study suggests.
Published Using mussels and silkworm cocoons to stop organ bleeding
(via sciencedaily.com) Original source A collaborative research team develops an absorbent multifunctional nanofiber adhesive hemostat based on a protein biomaterial.
Published Killer instinct drove evolution of mammals' predatory ancestors
(via sciencedaily.com) Original source The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers suggest.
Published Mice surprise: Researchers discover new native species
(via sciencedaily.com) Original source Australia can lay claim to two new species of native rodent thanks to a new study. The aptly named delicate mouse was previously thought to be a single species spanning a massive stretch of the country from the Pilbara in Western Australia, across parts of the Northern Territory and through Queensland down to the New South Wales border. We now know there are three distinct species.
Published A new vibrant blue pottery pigment with less cobalt
(via sciencedaily.com) Original source Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less cobalt but still maintains a brilliant shine. Though something like this might only happen once in a blue moon, the cobalt-doped barium aluminosilicate colorant withstands the high temperatures found in a kiln and provides a bright color to glazed tiles.
Published Modeling tree masting
(via sciencedaily.com) Original source The effects of a phenomenon called tree masting on ecosystems and food webs can be better understood thanks to new theoretical models validated by real world observations.
Published Physicists discover a quantum state with a new type of emergent particles: Six-flux composite fermions
(via sciencedaily.com) Original source Physicists have reported a new fractional quantum Hall state that is very different from all other known fractional states and will invoke the existence of a new type of emergent particle, which they are calling six-flux composite fermions.
Published Weedy rice gets competitive boost from its wild neighbors
(via sciencedaily.com) Original source Weedy rice is an agricultural pest with a global economic impact. It is an aggressive weed that outcompetes cultivated rice and causes billions of dollars in yield losses worldwide. A study offers new insights into genetic changes that give weedy rice its edge over cultivated rice in tropical regions of the world.
Published Mercury levels in tuna remain nearly unchanged since 1971
(via sciencedaily.com) Original source Tuna is one of the most popular seafoods worldwide. But this protein-rich fish can build up high levels of methylmercury from feeding on contaminated prey, like smaller fish or crustaceans. Despite efforts to reduce mercury emissions into the environment, researchers report that levels in tuna appear to be unchanged since 1971. They warn that more aggressive emission reduction targets are needed to start nudging down tuna mercury levels.
Published Kiss-and-tell: A new method for precision delivery of nanoparticles and small molecules to individual cells
(via sciencedaily.com) Original source The delivery of experimental materials to individual cells with exactness and exclusivity has long been an elusive and much sought-after ability in biology. With it comes the promise of deciphering many longstanding secrets of the cell. A research team has now successfully shown how small molecules and single nanoparticles can be applied directly onto the surface of cells. In the study the scientists describe their technique as a ' kiss' (microkiss) -- an easy and cost-effective new method, unlocking new possibilities in single-cell science with a view towards next generation therapeutic applications.
Published An environmentally friendly way to turn seafood waste into value-added products
(via sciencedaily.com) Original source Reduce, reuse, recycle, and repurpose: These are all ways we can live more sustainably. One tricky aspect of recycling, though, is that sometimes the recycling process is chemically intensive, and this is the case for recycling one of the world's most abundant materials -- chitin. Researchers have tackled this problem and found a way to sustainably recover chitin from seafood waste.
Published Toxic elements found in stranded whales, dolphins over 15 years
(via sciencedaily.com) Original source Researchers evaluated the prevalence, concentration and tissue distribution of essential and non-essential trace elements, including heavy metal toxicants in tissue (blubber, kidney, liver, skeletal muscle, skin) and fecal samples collected from 90 whales and dolphins stranded in Georgia and Florida from 2007 to 2021.
Published Electrons become fractions of themselves in graphene
(via sciencedaily.com) Original source Physicists have observed fractional quantum Hall effect in simple pentalayer graphene. The finding could make it easier to develop more robust quantum computers.
Published Scientists invent ultra-thin, minimally-invasive pacemaker controlled by light
(via sciencedaily.com) Original source A team of researchers has developed a wireless device, powered by light, that can be implanted to regulate cardiovascular or neural activity in the body. The feather-light membranes, thinner than a human hair, can be inserted with minimally invasive surgery and contain no moving parts.
Published Engineering a coating for disease-free produce
(via sciencedaily.com) Original source Texas A&M researchers combine food-grade wax with essential oils to defend produce from bacteria.
Published Engineers achieve breakthrough in quantum sensing
(via sciencedaily.com) Original source A collaborative project has made a breakthrough in enhancing the speed and resolution of wide-field quantum sensing, leading to new opportunities in scientific research and practical applications.
Published Using metabolomics for assessing safety of chemicals may reduce the use of lab rats
(via sciencedaily.com) Original source Scientists have discovered a more robust way of grouping chemicals and using read-across for toxicological data to meet regulatory requirements, which could greatly reduce animal testing.
Published It's the spin that makes the difference
(via sciencedaily.com) Original source Biomolecules such as amino acids and sugars occur in two mirror-image forms -- in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.
