Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published To ward off aging, stem cells must take out the trash
(via sciencedaily.com) Researchers find stem cells use a surprising system for discarding misfolded proteins. This unique pathway could be the key to maintaining long-term health and preventing age-related blood and immune disorders.
Published How the 'marsupial sabertooth' thylacosmilus saw its world
(via sciencedaily.com) A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.
Published Forest growing season in eastern U.S. has increased by a month
(via sciencedaily.com) The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
Published Lone star tick bites may be to blame for unexplained digestive problems
(via sciencedaily.com) New clinical guidance has been developed to help physicians and patients identify if unexplained digestive symptoms are due to alpha-gal syndrome, a food allergy that is caused by lone star tick bites.
Published Biodiversity amid climate change
(via sciencedaily.com) Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.
Published In hot water: Ocean warming impacts growth, metabolic rate and gene activity of newly hatched clownfish
(via sciencedaily.com) Future ocean warming and marine heatwaves could impact the growth and development of clownfish during their earliest life stages, suggests a new study.
Published Scientists use tardigrade proteins for human health breakthrough
(via sciencedaily.com) Original source Natural and engineered versions of tardigrade proteins can be used to stabilize an important pharmaceutical used to treat people with hemophilia and other conditions without the need for refrigeration -- even amid high temperatures and other difficult conditions.
Published Recycling: Researchers separate cotton from polyester in blended fabric
(via sciencedaily.com) Researchers found they could separate blended cotton and polyester fabric using enzymes -- nature's tools for speeding chemical reactions. Ultimately, they hope their findings will lead to a more efficient way to recycle the fabric's component materials, thereby reducing textile waste.
Published Genome research: Origin and evolution of vine
(via sciencedaily.com) Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.
Published Coffee plantations limit birds' diets
(via sciencedaily.com) A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.
Published Inbreeding contributes to decline of endangered killer whales
(via sciencedaily.com) The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their decline, which has continued as surrounding killer whale populations expand, according to new research.
Published Muscle health depends on lipid synthesis
(via sciencedaily.com) Original source Muscle degeneration, the most prevalent cause of frailty in hereditary diseases and aging, could be caused by a deficiency in one key enzyme in a lipid biosynthesis pathway. Researchers now characterize how the enzyme PCYT2 affects muscle health in disease and aging in laboratory mouse models.
Published Scholars unify color systems using prime numbers
(via sciencedaily.com) Existing color systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colors, making them difficult to compute and time-consuming to convert. Recently, researchers made a breakthrough by inventing an innovative color system, called 'C235', based on prime numbers, enabling efficient encoding and effective color compression. It can unify existing color systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colorizing DNA codons.
Published Chromo-encryption method encodes secrets with color
(via sciencedaily.com) In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published Video game playing causes no harm to young children's cognitive abilities, study finds
(via sciencedaily.com) Despite old fears that bad effects follow excessive video game playing or questionable game choices, researchers found those factors mattered little, if any, in children's brain health. The bad news? Video games assumed to be effective learning tools showed no meaningful effects, either.
Published Purchasing loot boxes in video games associated with problem gambling risk, says study
(via sciencedaily.com) Gamers who buy 'loot boxes' are up to two times more likely to gamble, shows new research.
Published Online gaming enhances career prospects and develops soft skills, finds new study
(via sciencedaily.com) Online gaming behavior can encourage gamers to gain a variety of soft skills which could assist them with training to support their career aspirations, according to new research.
Published Microlaser chip adds new dimensions to quantum communication
(via sciencedaily.com) With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.
Published Mathematicians explain how some fireflies flash in sync
(via sciencedaily.com) A new study by mathematicians shows that math borrowed from neuroscience can describe how swarms of these unique insects coordinate their light show, capturing key details about how they behave in the wild.
