Published Listen to a star 'twinkle'
(via sciencedaily.com) Original source Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.
Published How to move communities away from flooding risks with minimal harm
(via sciencedaily.com) Original source As sea levels rise and flooding becomes more frequent, many countries are considering a controversial strategy: relocation of communities. A Stanford analysis of planned relocations around the world reveals a blueprint for positive outcomes.
Published Bacteria as Blacksmiths
(via sciencedaily.com) Original source A hot bath is a place to relax. For scientists, it is also where molecules or tiny building blocks meet to form materials. Researchers take it to the next level and use the energy of swimming bacteria to forge materials. A recent study shows us how this works and the potential sustainability benefits that may arise from this innovative approach.
Published Making renewable, infinitely recyclable plastics using bacteria
(via sciencedaily.com) Original source Scientists engineered microbes to make the ingredients for recyclable plastics -- replacing finite, polluting petrochemicals with sustainable alternatives. The new approach shows that renewable, recyclable plastics are not only possible, but also outperform those from petrochemicals.
Published New technology promises rapid and reliable development of new diagnostic tests
(via sciencedaily.com) Researchers have developed a new approach for designing molecular ON-OFF switches based on proteins which can be used in a multitude of biotechnological, biomedical and bioengineering applications.
Published New study reveals that tree species diversity increases spider density
(via sciencedaily.com) Original source The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.
Published Bees and wasps use the same architectural solutions to join large hexagons to small hexagons
(via sciencedaily.com) Original source Bees and wasps have converged on the same architectural solutions to nest-building problems, according to new research.
Published Researchers develop 'in vivo' RNA-based gene editing model for blood disorders
(via sciencedaily.com) Original source In a step forward in the development of genetic medicines, researchers have developed a proof-of-concept model for delivering gene editing tools to treat blood disorders, allowing for the modification of diseased blood cells directly within the body. If translated into the clinic, this approach could expand access and reduce the cost of gene therapies for blood disorders, many of which currently require patients receive chemotherapy and a stem cell transplant.
Published 'Swine flu' strain has passed from humans to swine nearly 400 times since 2009
(via sciencedaily.com) Original source A new study of the strain of influenza A responsible for the 2009 H1N1 pandemic -- pdm09 -- shows that the virus has passed from humans to swine about 370 times since 2009, and subsequent circulation in swine has resulted in the evolution of pdm09 variants that then jumped from swine to humans.
Published New insights into the origin of the Indo-European languages
(via sciencedaily.com) Original source An international team of linguists and geneticists has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population.
Published Genome analysis of 46,000-year-old roundworm from Siberian permafrost reveals novel species
(via sciencedaily.com) Original source Some organisms, such as tardigrades, rotifers, and nematodes, can survive harsh conditions by entering a dormant state known as 'cryptobiosis.' In 2018, researchers found two roundworms (nematode) species in the Siberian Permafrost. Radiocarbon dating indicated that the nematode individuals have remained in cryptobiosis since the late Pleistocene, about 46,000 years ago. Researchers have now used genome sequencing, assembly, and phylogenetic analysis and found that the permafrost nematode belongs to a previously undescribed species, Panagrolaimus kolymaensis.
Published New research method determines health impacts of heat and air quality
(via sciencedaily.com) Original source The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.
Published Using cosmic weather to study which worlds could support life
(via sciencedaily.com) As the next generation of giant, high-powered observatories begin to come online, a new study suggests that their instruments may offer scientists an unparalleled opportunity to discern what weather may be like on far-away exoplanets.
Published Webb snaps highly detailed infrared image of actively forming stars
(via sciencedaily.com) Original source Young stars are rambunctious! NASA's James Webb Space Telescope has captured the 'antics' of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.
Published A simpler method for learning to control a robot
(via sciencedaily.com) A new machine-learning technique can efficiently learn to control a robot, leading to better performance with fewer data.
Published Fast electrical signals mapped in plants with new bioelectronic technology
(via sciencedaily.com) Original source What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress.
Published Aphids make tropical milkweed less inviting to monarch butterflies
(via sciencedaily.com) Original source When oleander aphids infested tropical milkweed, monarch butterflies laid fewer eggs on the plant, and the caterpillars developing on those plants were slower to mature.
Published Climate change threatens 771 endangered plant and lichen species
(via sciencedaily.com) Original source All plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change but there are few plans in place to address this threat directly, according to new research.
Published Ancient DNA reveals diverse community in 'Lost City of the Incas'
(via sciencedaily.com) Original source DNA analysis of 34 individuals buried at Machu Picchu revealed that many traveled alone from throughout the Inca Empire.
Published New planetary formation findings
(via sciencedaily.com) Astronomers have discovered new evidence of how planets as massive as Jupiter can form.
