Published First live birth of a chimeric monkey using embryonic stem cell lines
(via sciencedaily.com) Original source A team of researchers has reported for the first time the live birth of a monkey that contains a high proportion of cells derived from a monkey stem cell line. This 'chimeric' monkey is composed of cells that originate from two genetically distinct embryos of the same species of monkey. This has previously been demonstrated in rats and mice but, until now, has not been possible in other species, including non-human primates.
Published Reducing vitamin B5 slows breast cancer growth in mice
(via sciencedaily.com) Original source Researchers have discovered that breast cancer cells expressing a cancer-driving gene heavily rely on vitamin B5 to grow and survive.
Published Zen and the art of mitochondrial maintenance: The machinery of death makes a healthier life
(via sciencedaily.com) Original source While we all aspire for a long lifespan, what is most coveted is a long period of vigor and health, or 'healthspan,' that precedes the inevitable decline of advancing age. Researchers have discovered that instruments of death that cells use to commit suicide when things go wrong contribute to making a longer and healthier life by revitalizing the specialized cellular compartments called mitochondria.
Published Artificial bladders shine light on bugs that cause urinary tract infections
(via sciencedaily.com) Original source A new study reveals that numerous bacterial strains are capable of hiding in the human bladder wall, suggesting why urinary tract infections often persist after treatment.
Published Temperature increase triggers viral infection
(via sciencedaily.com) Original source Researchers have mapped on an atomic level what happens in a virus particle when the temperature is raised.
Published How animals get their stripes and spots
(via sciencedaily.com) Original source New research helps explain how sharp patterns form on zebras, leopards, tropical fish and other creatures. Their findings could inform the development of new high-tech materials and drugs.
Published Head lice evolution mirrors human migration and colonization in the Americas
(via sciencedaily.com) Original source A new analysis of lice genetic diversity suggests that lice came to the Americas twice -- once during the first wave of human migration across the Bering Strait, and again during European colonization.
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 The secret to longer lasting batteries might be in how soap works
(via sciencedaily.com) Original source Researchers show that one of the most promising substances for designing longer lasting lithium batteries form micelle-like structures like they do in soap.
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 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 '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 Lightening the load: Researchers develop autonomous electrochemistry robot
(via sciencedaily.com) Original source Researchers have developed an automated laboratory robot to run complex electrochemical experiments and analyze data. The Electrolab will be used to explore next-generation energy storage materials and chemical reactions that promote alternative and sustainable energy.
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 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 Decarbonizing light-duty transportation in the United States: Study reveals strategies to achieve goal
(via sciencedaily.com) Original source Researchers found that meeting greenhouse gas emissions goals for light-duty vehicles, which are passenger vehicles such as cars and trucks, is possible, but not just by increasing electric vehicle sales.
