Published New study reveals huge potential for future waves of invasive species



Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.
Published Novel C. diff structures are required for infection, offer new therapeutic targets



Newly discovered iron storage 'ferrosomes' inside the bacterium C. diff -- the leading cause of hospital-acquired infections -- are important for infection in an animal model and could offer new targets for antibacterial drugs. They also represent a rare demonstration of a membrane-bound structure inside a pathogenic bacterium, upsetting the biological dogma that bacteria do not contain organelles.
Published Dangerous bee virus less deadly in at least one US forest



Researchers have found that the deadly deformed wing virus (DMV) in bees may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for preventing or treating the virus in managed colonies, researchers said.
Published Geese 'keep calm and carry on' after deaths in the flock



Canada geese strengthen existing friendships and forge a few new connections after losing close associates from their flock, new research shows.
Published Non-native species likely to continue spreading in North America, Australia and Europe



Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.
Published New discovery on how green algae count cell divisions illuminates key step needed for the evolution of multicellular life



An international research team has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division.
Published The Goldilocks Effect: Researchers establish framework for protein regulation



Researchers are working to understand how protein quality control works in cells.
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 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 A fifth of European Red List flora and fauna species may be at risk of extinction



A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
Published Feral horses and peatland carbon emissions



A ground-breaking new study has found carbon emissions from Australian alpine peatlands to be much higher in areas disturbed by feral horses.
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 First evidence of how the Asian malaria mosquito is spreading drug-resistant malaria in Africa



Research has led to the discovery of the role played by the Asian malaria mosquito (Anopheles stephensi) in the spread of drug and diagnosis-resistant malaria in Africa. Malaria is caused by a parasite which is spread by the bite of blood-sucking mosquitoes. According to the WHO, there were an estimated 247 million cases of malaria worldwide in 2021 with over 600,000 deaths, mostly in Africa. Children under 5 accounted for about 80% of all malaria deaths in the region.
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.
