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 Jellyfish size might influence their nutritional value
(via sciencedaily.com) Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.
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 'Green' hydrogen: How photoelectrochemical water splitting may become competitive
(via sciencedaily.com) Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, most systems based on this 'direct approach' have not been energetically competitive. However, the balance changes as soon as some of the hydrogen in such PEC cells is used in-situ for a catalytic hydrogenation reaction, resulting in the co-production of chemicals used in the chemical and pharmaceutical industries. The energy payback time of photoelectrochemical 'green' hydrogen production can be reduced dramatically, the study shows.
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 Parasites alter likelihood of fish being caught by anglers
(via sciencedaily.com) Parasitic infections in salmonid fish can increase or decrease their vulnerability to angling, depending on their body condition.
Published Hummingbirds use torpor in varying ways to survive cold temps
(via sciencedaily.com) Hummingbirds use the hibernation-like state of torpor in varying ways, depending on their physical condition and what is happening in their environment, according to new research.
Published 3D radar scan provides clues about threats to iconic Alaskan glacier
(via sciencedaily.com) Mapping a large coastal glacier in Alaska revealed that its bulk sits below sea level and is undercut by channels, making it vulnerable to accelerated melting in an already deteriorating coastal habitat.
Published Noise harming ocean invertebrates and ecosystems
(via sciencedaily.com) Noise from human activities is harming ocean invertebrates and ecosystems, new research shows.
Published Rivers and streams in the Andean Cordillera are hot spots for greenhouse gases emissions
(via sciencedaily.com) Researchers show that rivers in the Andean mountains contribute 35% and 72% of riverine emissions of carbon dioxide (CO2 ) and methane (CH4 ) in the Amazon basin, the world's largest river.
Published Electronic skin as flexible as crocodile skin
(via sciencedaily.com) A research team has developed a crocodile-skin-inspired omnidirectionally stretchable pressure sensor.
Published New approach to harvesting aerial humidity with organic crystals
(via sciencedaily.com) Researchers have reported a novel method of harvesting water from naturally occurring sources such as fog and dew.
Published Humans are altering the diet of Tasmanian devils, which may accelerate their decline
(via sciencedaily.com) New research shows how human-modified landscapes affect the diets of these marsupial scavengers.
Published Bigger flowers, greater rewards: Plants adapt to climate disruptions to lure pollinators
(via sciencedaily.com) There's been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures -- butterflies, bees, birds, bats and others -- that pollinate them.
Published Review of world water resources
(via sciencedaily.com) A recent review study provides an overview of the planet's freshwater supplies and strategies for sustainably managing them.
Published Where did Earth's water come from? Not melted meteorites, according to scientists
(via sciencedaily.com) A new study brings scientists one step closer to answering the question of where Earth's water came from.
Published Bird flu associated with hundreds of seal deaths in New England in 2022
(via sciencedaily.com) Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
Published New model provides improved air-quality predictions in fire-prone areas
(via sciencedaily.com) Globally, wildfires are becoming more frequent and destructive, generating a significant amount of smoke that can be transported thousands of miles, driving the need for more accurate air pollution forecasts. Researchers have now developed a deep learning model that provides improved predictions of air quality in wildfire-prone areas and can differentiate between wildfires and non-wildfires.
Published Microneedle-based drug delivery technique for plants
(via sciencedaily.com) The agriculture industry is under pressure to adopt sustainable and precise agricultural practices that enable more efficient use of resources due to worsening environmental conditions resulting from climate change, an ever-expanding human population, limited resources, and a shortage of arable land. As a result, developing delivery systems that efficiently distribute micronutrients, pesticides, and antibiotics in crops is crucial to ensuring high productivity and high-quality produce while minimising resource waste. However, current and standard practices for agrochemical application in plants are inefficient. These practices cause significant detrimental environmental side effects, such as water and soil contamination, biodiversity loss and degraded ecosystems; and public health concerns, such as respiratory problems, chemical exposure and food contamination.
