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 Physicists trap electrons in a 3D crystal
(via sciencedaily.com) Original source Physicists have trapped electrons in a pure crystal, marking the first achievement of an electronic flat band in a three-dimensional material. The results provide a new way for scientists to explore rare electronic states in 3D materials.
Published Scaling up nano for sustainable manufacturing
(via sciencedaily.com) Original source A research team has developed a high-performance coating material that self-assembles from 2D nanosheets, and which could significantly extend the shelf life of electronics, energy storage devices, health & safety products, and more. The researchers are the first to successfully scale up nanomaterial synthesis into useful materials for manufacturing and commercial applications.
Published Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks
(via sciencedaily.com) Original source Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the 'Meg'), they think their work suggests there are more warm-blooded sharks out there than previously believed, and -- based on the Meg's demise -- these species may be at great risk from warming seas.
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 Obesity linked to neurodegeneration through insulin resistance
(via sciencedaily.com) Original source Researchers have discovered a link between obesity and neurodegenerative disorders like Alzheimer's disease. Using the common fruit fly, the research shows that a high-sugar diet -- a hallmark of obesity -- causes insulin resistance in the brain, which in turn reduces the ability to remove neuronal debris, thus increasing the risk of neurodegeneration.
Published New dates for landslides reveal past Seattle fault earthquakes
(via sciencedaily.com) Original source New maps of more than 1,000 deep-seated landslides in the Puget Lowlands of Washington State provide evidence of the last major earthquake along the Seattle Fault about 1,100 years ago -- and may also hold traces of older earthquakes along the fault.
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 Window to the past: New microfossils suggest earlier rise in complex life
(via sciencedaily.com) Original source Microfossils may capture a jump in the complexity of life that coincided with the rise of oxygen in Earth's atmosphere and oceans, according to an international team of scientists.
Published Machine learning gives users 'superhuman' ability to open and control tools in virtual reality
(via sciencedaily.com) Original source Researchers have developed a virtual reality application where a range of 3D modelling tools can be opened and controlled using just the movement of a user's hand.
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 Infection with common cat-borne parasite associated with frailty in older adults
(via sciencedaily.com) Original source A new study of 601 older adults found that those with higher serointensity -- or a higher concentration of antibiodies -- to the cat-borne parasite Toxoplasma gondii are more likely to show signs of frailty, including exhaustion, loss of muscle mass and other indications of declining health. T. Gondii has previously been associated with risk-taking behavior and mental illness.
Published 'Hot' new form of microscopy examines materials using evanescent waves
(via sciencedaily.com) Original source A team of researchers has built a prototype microscope that does not rely on backscattered radiation, instead uses passive detection of thermally excited evanescent waves. They have examined dielectric materials with passive near-field spectroscopy to develop a detection model to further refine the technique, working to develop a new kind of microscopy for examining nanoscopic material surfaces.
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 French love letters confiscated by Britain finally read after 265 years
(via sciencedaily.com) Original source Over 100 letters sent to French sailors by their fianc es, wives, parents and siblings -- but never delivered -- have been opened and studied for the first time since they were written in 1757-8.
