Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery
(via sciencedaily.com) A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
Published New research brings greater understanding of Asian winter monsoon
(via sciencedaily.com) Original source Scientists have discovered a new technique which will shed light on the phenomena of winter monsoons -- the heavy autumn and winter rainfalls which can cause floods and landslides across southeast Asia.
Published Behavior is the secret to success for a range expansion
(via sciencedaily.com) Original source While many species are undergoing drastic declines in their numbers and geographic ranges, other species seem to be thriving. Researchers investigating the great-tailed grackle, a bird that has been establishing new populations across North America in the past few decades, reveal that behavior might play a key role in their success. They found that the population on the range's edge is more persistent and has more variability in flexibility, and that this species has shifted toward living more in urban, arid environments.
Published Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction
(via sciencedaily.com) Original source A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
Published Study shows life near the golf course isn't easy for alligators
(via sciencedaily.com) Original source Living on a golf course dramatically changes alligator feeding habits.
Published Gene required for root hair growth, nitrate foraging found in grasses
(via sciencedaily.com) Original source Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. The gene, dubbed 'BUZZ,' causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably.
Published Laser-based ice-core sampling for studying climate change
(via sciencedaily.com) Researchers have developed a new laser-based sampling system for studying the composition of ice cores taken from glaciers. The new system has a 3-mm depth-resolution and is expected to help reconstruct continuous annual temperature changes that occurred thousands to hundreds of thousands of years ago, which will help scientists understand climate change in the past and present.
Published Range of pesticides, including neonicotinoids, found in pollen of different bee species
(via sciencedaily.com) Original source New research paints a worrying picture for the different species of bees that provide multi-million-euro pollination services in Ireland each yea. The work raises concerns about the potential wide-spread exposure to multiple chemicals from two pesticide categories (fungicides and neonicotinoid insecticides) and indicates that different bee species may be exposed differently to pesticides -- meaning that assessments of pesticide risk to honey bees may not be easily extrapolated to other bees.
Published Cheap and efficient catalyst could boost renewable energy storage
(via sciencedaily.com) Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published RNA for the first time recovered from an extinct species
(via sciencedaily.com) Original source A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses.
Published Incubator or barrier? Exploring the links between agriculture, biodiversity and the spread of pathogens
(via sciencedaily.com) Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.
Published What is the carbon footprint of a hospital bed?
(via sciencedaily.com) Original source Researchers completed an assessment of a hospital to reveal its total environmental footprint and specific carbon emission hotspots.
Published Step change in upconversion the key to clean water, green energy and futuristic medicine
(via sciencedaily.com) Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
Published Almost half of koala habitats will be under high bushfire threat by 2070
(via sciencedaily.com) The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
Published Cars, chlamydia and canines are biggest koala killers
(via sciencedaily.com) Original source A database tracking hospital admissions and deaths reveals the devastating impact cars, disease and dogs are having on the South East Queensland koala population.
Published Clever lapwings use cover to hide in plain sight
(via sciencedaily.com) Original source Ground-nesting birds called lapwings use the shape of their nests and surroundings to hide from predators, new research shows.
Published Polar experiments reveal seasonal cycle in Antarctic sea ice algae
(via sciencedaily.com) Results provide the first measurements of how sea-ice algae and other single-celled life adjust to the dramatic seasonal rhythms in the Southern Ocean. The results provide clues to what might happen as this ecosystem shifts under climate change.
Published Genetically modified bacteria break down plastics in saltwater
(via sciencedaily.com) Original source Researchers have genetically engineered a marine microorganism to break down plastic in salt water. Specifically, the modified organism can break down polyethylene terephthalate (PET), a plastic used in everything from water bottles to clothing that is a significant contributor to microplastic pollution in oceans.
Published Vocal learning linked to problem solving skills and brain size
(via sciencedaily.com) Original source The better a songbird is at working its way around obstacles to retrieve a snack, the more complex its vocal learning ability will be.
Published Rivers are rapidly warming, losing oxygen; aquatic life at risk
(via sciencedaily.com) Original source Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.
