Published Color-changing material shows when medications get too warm
(via sciencedaily.com) Original source Some foods and medicines, such as many COVID-19 vaccines, must be kept cold. As a step toward a robust, stable technique that could indicate when these products exceed safe limits, researchers report a class of brilliantly colored microcrystals in materials that become colorless over a wide range of temperatures and response times. As a proof of concept, the team packaged the color-changing materials into a vial lid and QR code.
Published Eat right, live longer: Could a moderate protein diet be the coveted elixir of youth?
(via sciencedaily.com) Original source Consuming nutritious food can improve metabolic health and delay aging. But what are the appropriate quantities of dietary macronutrients that can help achieve this? To answer this, researchers fed isocaloric diets with varying amounts of protein to young and middle-aged male mice. They found that the mice were metabolically healthier when fed moderate-protein diets. These findings could provide valuable insights into developing nutritional interventions and improving metabolic health in people.
Published Fairy tales offer accessible ways to communicate energy research in the social sciences to help tackle climate change
(via sciencedaily.com) Original source A team of researchers has been developing accessible and creative means of communicating sustainability research from the social sciences for policymakers and the wider public. Using fairy tale characters -- mermaids, vampires, and witches -- as metaphors, the team has sought to communicate typically complicated arguments in evocative and engaging terms.
Published Saved from extinction, Southern California's Channel Island Foxes now face new threat to survival
(via sciencedaily.com) Original source Starting in the 1990s, Island Fox populations began to dwindle due to an outbreak of canine distemper and an increase in attacks by golden eagles. Some islands saw their population drop to as low as 15 individuals, but conservation efforts by the Federal government restored numbers by 2017. A new study reveals a worrying decrease in genetic diversity within the species, signaling a new threat to the Channel Islands foxes' survival. The decrease in genetic diversity reduces the foxes' ability to adapt to future challenges, such as climate change and introduced pathogens, putting their survival at risk once again. Although the foxes have low genetic diversity, they possess diverse gut microbiomes that could help them cope with environmental changes.
Published Shedding light on the complex flow dynamics within the small intestine
(via sciencedaily.com) Original source A novel microfluidic device revealing diverse and dynamic flows in the small intestine has now been developed. An innovative experimental platform uses microscopic fluorescent beads as substitutes for gut bacteria in dissected small intestine sections, allowing one to visualize and quantitatively analyze the luminal dynamic flow in the tissues deformed by a pneumatic actuator.
Published The clams that fell behind, and what they can tell us about evolution and extinction
(via sciencedaily.com) Original source A new study examined how bivalves -- the group that includes clams, mussels, scallops, and oysters -- evolved among many others in the period of rapid evolution known as the Cambrian Explosion. The team found that though many other lineages burst into action and quickly evolved a wide variety of forms and functions, the bivalves lagged behind. The study has implications for how we understand evolution and the impact of extinctions.
Published Genetic change increased bird flu severity during U.S. spread
(via sciencedaily.com) Original source Scientists found the virus strains that arrived in 2021 soon acquired genes from viruses in wild birds in North America. The resulting reassortant viruses have spread across the continent and caused more severe disease.
Published Flexible nanoelectrodes can provide fine-grained brain stimulation
(via sciencedaily.com) Original source Engineers have developed ultraflexible implantable nanoelectrodes that can administer long-term, fine-grained brain stimulation.
Published Researchers use 'natural' system to identify proteins most useful for developing an effective HIV vaccine
(via sciencedaily.com) Original source Scientists have spent years trying to develop an effective HIV vaccine, but none have proven successful. Based on findings from a recently published study, a research team may have put science one step closer to that goal.
Published Light conveyed by the signal transmitting molecule sucrose controls growth of plant roots
(via sciencedaily.com) Original source Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal transmitter for light-dependent root architecture.
Published World leading health experts say aviation industry must act on cabin fumes as they launch new medical guidance
(via sciencedaily.com) Original source A group of world leading health and scientific experts are calling on the aviation industry to take action to protect passengers and aircrew from dangerous cabin fumes which they say have led to a new emerging disease. Led by former pilot and aviation health researcher, the specialists have released the first medical protocol of its kind to help treat those effected by contamination of the aircraft cabin breathing air supply and collect data on contamination events.
Published Quest for alien signals in the heart of the Milky Way takes off
(via sciencedaily.com) Original source A graduate student is spearheading an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy.
Published Mitigating climate change through restoration of coastal ecosystems
(via sciencedaily.com) Original source Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.
Published New catalyst lowers cost for producing environmentally sustainable hydrogen from water
(via sciencedaily.com) Original source A team has developed a new catalyst composed of elements abundant in the Earth. It could make possible the low-cost and energy-efficient production of hydrogen for use in transportation and industrial applications.
Published Extreme precipitation in Northeast US to increase 52% by the end of the century
(via sciencedaily.com) Original source With a warmer climate creating more humid conditions in the Northeast, extreme precipitation events -- defined as about 1.5 or more inches of heavy rainfall or melted snowfall in a day -- are projected to increase in the Northeast by 52% by the end of the century, according to a new study.
Published That's not nuts: Almond milk yogurt packs an overall greater nutritional punch than dairy-based
(via sciencedaily.com) Original source In a nutritional comparison of plant-based and dairy yogurts, almond milk yogurt came out on top, according to new research.
Published Towering plume of water escaping from Saturn moon
(via sciencedaily.com) Original source Scientists have observed a towering plume of water vapor more than 6,000 miles long -- roughly the distance from the U.S. to Japan -- spewing from the surface of Saturn's moon, Enceladus.
Published How insects track odors by navigating microscale winds
(via sciencedaily.com) Original source Insects use odor plumes -- which travel like smoke and form when the wind blows odor molecules from their source -- to track down sources such as flowers or pheromones. But wind tunnels are typically unable to replicate realistic outdoor wind conditions. Researchers decided to explore microscale wind conditions in various outdoor environments to better understand what flying insects might experience while tracking odor plumes.
Published Reusable packaging revolution is close
(via sciencedaily.com) Original source A detailed plan to transform product packaging and significantly cut plastic production and pollution has been developed by researchers. The study comes as government representatives meet in Paris to negotiate a legally binding global plastics treaty with a mandate to end plastic pollution.
