  • Modern plant enzyme partners with surprisingly ancient protein
    Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.
  • Plants restrict use of 'Tipp-Ex proteins'
    Plants have special corrective molecules at their disposal that can make retrospective modifications to copies of genes. However, it would appear that these 'Tipp-Ex proteins' do not have permission to work in all areas of the cell, only being used in chloroplasts and mitochondria. A study has now explained why this is the case. It suggests that the correction mechanism would otherwise modify copies that have nothing wrong with them, with fatal consequences for the cell.
  • Fruit fly wing research offers window into birth defects
    If fruit fly wings do not develop into the right shape, the flies will die. Researchers have learned how fly embryo cells develop as they need to, opening a window into human development and possible treatments for birth defects.
  • Ancient arachnid from coal forests of America stands out for its spiny legs
    The spiny legged 308-million-year-old arachnid Douglassarachne acanthopoda was discovered the famous Mazon Creek locality.
  • Natural toxins in food: Many people are not aware of the health risks
    Many people are concerned about residues of chemicals, contaminants or microplastics in their food. However, it is less well known that many foods also contain toxins of completely natural origin. These are often chemical compounds that plants use to ward off predators such as insects or microorganisms. These substances are found in beans and potatoes, for example, and can pose potential health risks.
  • Bioengineered enzyme creates natural vanillin from plants in one step
    Vanilla, the most widely used flavoring compound in confectionaries and cosmetics, gets its sweet flavor and aroma from the chemical compound -- 'vanillin'. However, the large-scale production of natural vanillin is impeded by the lack of microbial processes and enzymes which can commercially generate vanillin. Now, researchers have genetically engineered a novel enzyme which can convert ferulic acid from plant waste into vanillin in a one-step sustainable process.
  • Regenerating worms have genetic control over their algal partners
    Researchers have found a genetic pathway that facilitates inter-species communication between a marine worm, acoel, and its symbiotic algae.
  • From roots to resilience: investigating the vital role of microbes in coastal plant health
    Understanding how salt marsh grass stays healthy is of crucial ecological importance, and studying the ways bacteria interact with these plants is key. Thanks to recent advances in genomic technology, biologists have begun to reveal never-before-seen ecological processes.
  • Now we know, what gets roots to grow: Can help in future droughts
    A biological mechanism familiar to people who fast helps plant roots grow strong. The discovery provides an answer to a long-unanswered question and a deeper understanding of the 'mouths' of plants that can help to develop climate-resilient crops.
  • Exploring the mechanism behind drug eruptions in the skin
    Although drug eruptions are often linked to the human leukocyte antigen (HLA), the mechanism of its involvement in presenting symptoms of the skin remains unclear. In a recent study, researchers used genetically engineered mice to demonstrate the role of HLA in mediating intracellular reactions in keratinocytes, leading to drug eruptions in the skin. Their findings could lead to improved preventive and treatment measures for drug eruptions.
  • Climate change is most prominent threat to pollinators
    A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
  • Drug compounds to combat neurodegenerative diseases
    Prions are the abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins. Prion disease is an umbrella term for a group of fatal and currently untreatable neurodegenerative diseases that not only affect humans, but also wild and captive animals. These diseases include Creutzfeldt-Jakob disease (CJD) in humans, bovine spongiform encephalopathy (BSE, or 'mad cow disease'), and chronic wasting disease (CWD) affecting deer, elk and moose.
  • Highly pathogenic avian flu detected in New York City wild birds
    A small number of New York City wild birds carry highly pathogenic H5N1 avian influenza, according to a recent study.
