Published The fascinating relationship between mice and a plant that flowers once a century in terms of seed dispersal
(via sciencedaily.com) Original source Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.
Published New algae species rewrites understanding of reef systems
(via sciencedaily.com) Original source An international team of marine scientists has identified and officially named four species of algae new to science, challenging previous taxonomical assumptions within the Porolithon genus. The discovery has far-reaching implications for our understanding of the ecological role of these algae in the coral reef ecosystem.
Published Threatened sharks and rays caught off Cyprus
(via sciencedaily.com) Original source Sharks and rays from threatened species are being caught off northern Cyprus, according to a new study by scientists who are working with local authorities and fishers to protect the animals.
Published Fossils tell tale of last primate to inhabit North America before humans
(via sciencedaily.com) Original source Paleontologists have shed light on the long-standing saga of Ekgmowechashala, based on fossil teeth and jaws found in both Nebraska and China. Ekgmowechashala is the last primate found in the fossil record before humans.
Published Crust-forming algae are displacing corals in tropical waters worldwide
(via sciencedaily.com) Original source Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.
Published Large herbivores such as elephants, bison and moose contribute to tree diversity
(via sciencedaily.com) Original source Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests
(via sciencedaily.com) Original source Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published To restore ecosystems, think about thwarting hungry herbivores
(via sciencedaily.com) Original source Re-establishing plantings of trees, grasses and other vegetation is essential for restoring degraded ecosystems, but a new survey of almost 2,600 restoration projects from nearly every type of ecosystem on Earth finds that most projects fail to recognize and control one of the new plants' chief threats: hungry critters that eat plants.
Published Researchers discover new ultra strong material for microchip sensors
(via sciencedaily.com) Original source Researchers have unveiled a remarkable new material with potential to impact the world of material science: amorphous silicon carbide (a-SiC). Beyond its exceptional strength, this material demonstrates mechanical properties crucial for vibration isolation on a microchip. Amorphous silicon carbide is therefore particularly suitable for making ultra-sensitive microchip sensors.
Published Researchers engineer colloidal quasicrystals using DNA-modified building blocks
(via sciencedaily.com) Original source A new study unveils a novel methodology to engineer colloidal quasicrystals using DNA-modified building blocks. The implications of this breakthrough are far-reaching, offering a potential blueprint for the controlled synthesis of other complex structures previously considered beyond reach.
Published Buzz around new centralized pollination portal for better global bee data
(via sciencedaily.com) Original source A powerful new way to fill major gaps in public bee data -- including from Africa, Asia and other under-reported zones -- has been addressed with a centralized tool for consolidating bee pollinator occurrences around the globe.
Published New twist on optical tweezers
(via sciencedaily.com) Original source Optical tweezers use laser light to manipulate small particles. A new method has been advanced using Stampede2 supercomputer simulations that makes optical tweezers safer to use for potential biological applications, such as cancer therapy.
Published Shifting nesting timing not enough to prevent fewer sea turtle hatchlings
(via sciencedaily.com) Original source New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.
Published New map of 20th century land use in Britain helps researchers demystify biodiversity change
(via sciencedaily.com) Original source Researchers have mapped how land use changed across Britain throughout the last century. The new map reveals how and where some 50 per cent of semi-natural grassland was lost, including 90 per cent of the country's lowland meadows and pasture, as the nation intensified its agriculture.
Published Photography: One-stop solution for shaping and outlining objects
(via sciencedaily.com) Original source A joint research team has developed a dual metalens that can switch between shooting modes based on light conditions.
Published Australasia's hidden pollination crisis could threaten biodiversity and food security
(via sciencedaily.com) Original source Australasia's hidden pollination crisis, mirroring global threats, could pose a significant risk to regional biodiversity and food security, new research has found.
Published Amazon deforestation linked to long distance climate warming
(via sciencedaily.com) Original source Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study. The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.
Published Amphibians have one more thing to worry about--mercury
(via sciencedaily.com) Original source The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels.
Published Offset markets: New approach could help save tropical forests by restoring faith in carbon credits
(via sciencedaily.com) Original source A new approach to valuing the carbon storage potential of natural habitats aims to help restore faith in offset schemes, by enabling investors to directly compare carbon credit pricing across a wide range of projects.
Published 'Plug and play' nanoparticles could make it easier to tackle various biological targets
(via sciencedaily.com) Original source Engineers have developed modular nanoparticles that can be easily customized to target different biological entities such as tumors, viruses or toxins. The surface of the nanoparticles is engineered to host any biological molecules of choice, making it possible to tailor the nanoparticles for a wide array of applications, ranging from targeted drug delivery to neutralizing biological agents.
