Published Identifying a silicon transporter to improve the yield of rice
(via sciencedaily.com) Original source Researchers identify a membrane transporter in rice that regulates the accumulation and localization of silicon in the leaves.
Published Device 'smells' seawater to discover, detect novel molecules
(via sciencedaily.com) Original source Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
Published The metabolism of bacteria under the microscope: New method reveals host-microbe interactions
(via sciencedaily.com) Original source The fascinating world of bacteria that live as symbionts or parasites in animal hosts often remains a mystery to researchers. A research team has made a breakthrough that provides insights into this mysterious micro-world.
Published Yeast with an over half synthetic genome is created in the lab
(via sciencedaily.com) Original source Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. A global consortium is working to develop the first synthetic eukaryote genome from scratch. The team has now synthesized and debugged all sixteen yeast chromosomes.
Published Scientists one step closer to re-writing world's first synthetic yeast genome, unravelling the fundamental building blocks of life
(via sciencedaily.com) Original source Scientists have engineered a chromosome entirely from scratch that will contribute to the production of the world's first synthetic yeast.
Published Scientists take major step towards completing the world's first synthetic yeast
(via sciencedaily.com) Original source A team of Scientists has completed construction of a synthetic chromosome as part of a major international project to build the world's first synthetic yeast genome. The work represents completion of one of the 16 chromosomes of the yeast genome, which is part of the biggest project ever in synthetic biology; the international synthetic yeast genome collaboration. The collaboration, known as 'Sc2.0' has been a 15-year project involving teams from around the world (UK, US, China, Singapore, UK, France and Australia), working together to make synthetic versions of all of yeast's chromosomes. Alongside this paper, another 9 publications are also released today from other teams describing their synthetic chromosomes. The final completion of the genome project -- the largest synthetic genome ever -- is expected next year.
Published Deep decarbonization scenarios reveal importance of accelerating zero-emission vehicle adoption
(via sciencedaily.com) Original source The rapid adoption of zero-emission electric vehicles will move the nation close to an 80% or more drop in transportation greenhouse gas emissions by 2050 from the 2019 level according to researchers.
Published Maps reveal biochar's potential for mitigating climate change
(via sciencedaily.com) Original source Twelve countries have the technical ability to sequester over 20% of their current total greenhouse gas emissions by converting crop residues to biochar. Bhutan leads the way with the potential to sequester 68% of its emissions in the form of biochar, followed by India, at 53%.
Published Cracking the code: Genome sequencing reveals why songbirds are larger in colder climates
(via sciencedaily.com) Original source Scientists have unlocked the genetic basis underlying the remarkable variation in body size observed in song sparrows, one of North America's most familiar and beloved songbirds. This discovery also provides insights into this species' capacity to adapt to the challenges of climate change. The study used genomic sequencing to successfully pinpoint eight genetic variants, or DNA mutations, largely responsible for the nearly threefold difference in body size observed across the song sparrow range from Mexico to Alaska.
Published Africa's dangerous air pollution levels are a global problem, says new research
(via sciencedaily.com) Original source A new report has brought to light the challenge of air pollution levels in Africa and why international action is needed to combat it.
Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com) Original source AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published A database unifies the information on damage to European forests over the last 60 years
(via sciencedaily.com) Original source Researchers are creating a database that harmonizes the recording of disturbances caused by insects and diseases in forests in 8 European countries by combining remote sensing, satellite images and field data.
Published 450-million-year-old organism finds new life in Softbotics
(via sciencedaily.com) Original source Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Experiment shows biological interactions of microplastics in watery environment
(via sciencedaily.com) Original source Scientists have learned over the years that when aquatic organisms such as zooplankton become exposed to microplastics, they eat poorly. Research now shows that their plastic-induced eating difficulties also limit the ability of zooplankton to control algal proliferation. When algae bloom out of control, this presents a problem because some species produce toxins. Also, algal blooms can be associated with pea-soupy, unattractive bodies of water and contribute to hypoxia, a low-oxygen condition that may lead to fish kills.
Published Energy transition: A super-model to guide policy makers
(via sciencedaily.com) Original source How can we ensure that an energy policy will achieve its objectives? To find out, scientists and public authorities can rely on computer models of varying degrees of accuracy. However, these models have a number of limitations, including the fact that they are not very effective for generating projections on a regional scale. A team has now designed a super-model to simulate the spread of three green technologies.
Published Plants' ingenious defense against mutational damage
(via sciencedaily.com) Original source How do plants deal with mutations in their 'power stations'? By exploiting randomness to create diversity, say researchers.
Published We can save lives and millions with less nitrate in drinking water
(via sciencedaily.com) Original source Denmark could save lives and more than $300 million a year by reducing the amount of nitrate in its drinking water. An ever-growing body of research concludes that the amount of nitrate in some Danish boreholes increases the risk of colorectal cancer.
Published Food waste prevention in Europe can generate major footprint savings
(via sciencedaily.com) Original source New calculations show that the European countries have great potential for reducing the demand for global food resources and the associated GHG footprint. Researchers have estimated the climate footprint savings that may be obtained from reducing food loss and waste along Europe's food supply chain by 50 % by 2030.
Published Electric vehicles are driven less than gas cars
(via sciencedaily.com) Original source One of the largest studies to date finds the current generation of EV owners drive far fewer miles than owners of gas vehicles, translating to lower emissions savings from EVs.
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.
