• New study explores plant adaptations to drought and cold stress

    Recent advances in technology have allowed scientists to probe the molecular nature of life, analyzing thousands of genes at a time and recognizing patterns of gene interaction. In a recent paper published in Proceedings of the Royal Society B, complexity scientist Samuel Scarpino and co-authors explore gene co-expression networks that have evolved to help plants withstand drought and cold.

  • Scientists build giant 'molecular cages' for energy conversion and drug delivery

    Scientists from Trinity College Dublin and AMBER, the Science Foundation Ireland-funded materials science research centre hosted in Trinity College Dublin, have created ‘molecular cages’ that can maximise the efficiency of converting molecules in chemical reactions, and that may in future also be used as sensors and drug-delivery agents. The cages can be packed with different molecules, many of which have a specific task or functionality.

  • Canada +150: DNA Barcodes — Sci-Fi Tech to Safeguard Environment

    A Canadian technology that can identify a substance by scanning it — as a character in Star Trek might — could become a crucial tool to capture DNA data in the environment and protect it.

    DNA barcoding, developed at the University of Guelph by Professor Paul Hebert, uses genetic variations to identify different species. It’s similar to how a supermarket checkout scanner reads variations in a UPC barcode’s lines to identify a product you buy.

  • Turning the Climate Tide by 2020

    The world needs high-speed climate action for an immediate bending-down of the global greenhouse-gas emissions curve, leading experts caution. Aggressive reduction of fossil-fuel usage is the key to averting devastating heat extremes and unmanageable sea level rise, the authors argue in a comment published in the renowned scientific journal Nature this week. In the run-up to the G20 summit of the planet’s leading economies, the article sets six milestones for a clean industrial revolution. This call for strong short-term measures complements the longer-term 'carbon law' approach introduced earlier this year by some of the current co-authors, including the Potsdam Institute’s Director Hans Joachim Schellnhuber, in the equally eminent journal Science. Thus a full narrative of deep decarbonization emerges.

  • NASA Keeps a Close Eye on Tiny Stowaways

    Wherever you find people, you also find bacteria and other microorganisms. The International Space Station is no exception.

    That generally is not a problem. For one thing, the space station is kept cleaner than many environments on Earth. Routine cleaning activities are included on astronaut task schedules. Cargo sent to the station, and the vehicles that carry it, undergo a rigorous cleaning process and monitoring for microorganisms before launch. Crew members assigned to the space station spend 10 days in pre-flight quarantine.

    For another, scientists regularly monitor the interior of this and other spacecraft, a process that started with the Apollo missions.

  • NASA Looks at Rainfall from Tropical Storm Dora

    Now a tropical storm, Hurricane Dora has been skirting southwestern Mexico’s coast since it formed and has transported tropical moisture onshore that has produced some heavy rain showers. The Global Precipitation Measurement mission or GPM core satellite has analyzed those rainfall rates.

  • Image analysis and artificial intelligence (AI) will change dairy farming

    A group of researchers led by Osaka University developed an early detection method for cow lameness (hoof disease), a major disease of dairy cattle, from images of cow gait with an accuracy of 99% or higher by applying human gait analysis. This technique allows early detection of lameness from cow gait, which was previously difficult. It is hoped that a revolution in dairy farming can be achieved through detailed observation by AI-powered image analysis.

  • Ruthenium rules for new fuel cells

    Rice University scientists have fabricated a durable catalyst for high-performance fuel cells by attaching single ruthenium atoms to graphene.

    Catalysts that drive the oxygen reduction reaction that lets fuel cells turn chemical energy into electricity are usually made of platinum, which stands up to the acidic nature of the cell’s charge-carrying electrolyte. But platinum is expensive, and scientists have searched for decades for a suitable replacement.

  • The trouble with being a handsome bird

    Male birds often use brightly coloured plumage to be attractive to females. However, such eye-catching trimmings may also attract unwanted attention from predators. Now, a new study led by Monash University has found that showy males indeed perceive themselves to be at a greater risk of predation.
