Published The Goldilocks Effect: Researchers establish framework for protein regulation



Researchers are working to understand how protein quality control works in cells.
Published Low-intensity fires reduce wildfire risk by 60%



High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.
Published Yeast cells can produce drugs for treatment of psychotic disorders



An international team of researchers has demonstrated that genetically engineered yeast cells can produce the natural plant product alstonine, which has shown positive effects in treating schizophrenia.
Published Team creates synthetic enzymes to unravel molecular mysteries



A bioengineer has developed synthetic enzymes that can control the behavior of the signaling protein Vg1, which plays a key role in the development of muscle, bone and blood in vertebrate embryos. The team of researchers is using a new approach, called the Synthetic Processing (SynPro) system, in zebrafish to study how Vg1 is formed. By learning the molecular rules of signal formation in a developing animal, researchers aim to engineer mechanisms -- such as giving cells new instructions -- that could play a role in treating or preventing disease.
Published Scientists use quantum biology, AI to sharpen genome editing tool



Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published First live birth of a chimeric monkey using embryonic stem cell lines



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 Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage



Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published Zen and the art of mitochondrial maintenance: The machinery of death makes a healthier life



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 Temperature increase triggers viral infection



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



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 Southern Alaska's national forests key to meeting climate, conservation goals



Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published Yeast with an over half synthetic genome is created in the lab



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 take major step towards completing the world's first synthetic yeast



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 Obesity linked to neurodegeneration through insulin resistance



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 Video technology could transform how scientists monitor changes in species evolution and development



New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests



Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published Research outlines how sex differences have evolved



Researchers have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type level.
Published Female sex determining gene identified in mice



Researchers have identified a gene which is an early determining factor of ovary development in mice.
Published A known environmental hazard can change the epigenetics of cells



An international team of researchers has discovered that formaldehyde, a widely spread pollutant and common metabolite in our body, interferes in the epigenetic programming of the cell. This finding expands the knowledge of formaldehyde, previously considered only as a DNA mutagen, and helps establishing a further link with cancer.
Published Immunology: Dysfunction of mitochondria drives the exhaustion of T cells



In the immune system's fight against cancer and infections, the T cells often lose their power. Now immunologists may have found a possible explanation for this phenomenon.
