• Teleconnection between the tropical Pacific and Antarctica

    In April 2016, a large-scale breakup of land-fast ice was observed in Lutzow-Holm Bay near Syowa Station, a Japanese research facility. It was the first comparably large calving in the region since 1998. Land-fast ice is sea ice that grows along the Antarctic coast and does not move much once formed. Syowa Station is normally surrounded by land-fast ice, which makes it very difficult for even an icebreaker to reach.

  • Warmer temperatures cause decline in key runoff measure

    Since the mid-1980s, the percentage of precipitation that becomes streamflow in the Upper Rio Grande watershed has fallen more steeply than at any point in at least 445 years, according to a new study led by the National Center for Atmospheric Research (NCAR).

  • More natural dust in the air improves air quality in eastern China

    Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study published May 11 in Nature Communications.

  • Methane-munching microbes living in the deep biosphere for 400 Million years - an analogue for extra-terrestrial life

    It is becoming more and more appreciated that a major part of the biologic activity is not going on at the ground surface, but is hidden underneath the soil down to depths of several kilometres in an environment coined the “deep biosphere”. Studies of life-forms in this energy-poor system have implications for the origin of life on our planet and for how life may have evolved on other planets, where hostile conditions may have inhibited colonization of the surface environment. The knowledge about ancient life in this environment deep under our feet is extremely scarce.

    In numerous cracks down to depths of 1700 meter that have been partly sealed by crystals grown in them, an international team of researchers led by Dr. Henrik Drake from Linnaeus University, Sweden, has traced fundamental ancient microbial processes, including production and consumption of the greenhouse gas methane. The multi-disciplinary approach included micro-scale measurement of stable isotopes coupled with geochronology within minerals formed in response to microbial activity at several Swedish granitic rock sites. This is the most extensive study on ancient microbial activity in the continental crust yet and the findings suggest that microbial methane formation and consumption are widespread in the bedrock.

  • Reaching for The Stormy Cloud with Chameleon

    Some scientists dream about big data. The dream bridges two divided realms. One realm holds lofty peaks of number-crunching scientific computation. Endless waves of big data analysis line the other realm. A deep chasm separates the two. Discoveries await those who cross these estranged lands.

    Unfortunately, data cannot move seamlessly between Hadoop (HDFS) and parallel file systems (PFS). Scientists who want to take advantage of the big data analytics available on Hadoop must copy data from parallel file systems. That can slow workflows to a crawl, especially those with terabytes of data.

  • Estimating the size of animal populations from camera trap surveys

    Remote motion-sensitive photography, or camera trapping, is revolutionizing surveys of wild animal populations. Camera trapping is an efficient means of detecting rare species, conducting species inventories and biodiversity assessments, estimating site occupancy, and observing behaviour. If individual animals can be identified from the images obtained, camera trapping data can also be used to estimate animal density and population size – information critical to effective wildlife management and conservation.

    For this reason, camera traps were initially popularized by researchers studying big cats and other species with distinctive coat markings. Since then, thousands of camera traps have been deployed in wildlife habitat across the globe, especially in tropical forest ecosystems where animals are difficult to survey by other means. However, methods for estimating abundances of species which cannot be individually identified are still in development, and none is generally accepted or broadly applied.

  • Uncovering the answer to an age-old question: how do snowflakes form?

    More than 400 years ago, renowned mathematician and scientist Johannes Kepler speculated about the creation of one of nature’s most angelic and unique shapes: the six-sided snowflake. Although atoms would not be discovered until two centuries later,  Kepler openly pondered about the microscopic building blocks that lead to the ice crystal’s hexagonal formation, including the myriad of factors behind this recurring phenomenon.

  • MIT researchers develop new way to clear pollutants from water

    When it comes to removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy- and chemical-intensive. Now, a new method developed at MIT could provide a selective alternative for removing even extremely low levels of unwanted compounds.

  • Quality text messaging by nurses and doctors linked to patient survival

    In medical emergencies, time is of the essence. So is the quality of communication. A team of researchers from York University, University Health Network (UHN) and Trillium Health Partners studied text messages sent between nurses and physicians in deteriorating internal medicine patients requiring escalation to intensive care unit (ICU) to identify issues in failures to rescue. Looking at records from 2012 to 2014 at the Toronto General Hospital, the team found that message quality was positively linked to survival.

  • Experiments show that a few self-driving cars can dramatically improve traffic flow

    The presence of just a few autonomous vehicles can eliminate the stop-and-go driving of the human drivers in traffic, along with the accident risk and fuel inefficiency it causes, according to new research. The finding indicates that self-driving cars and related technology may be even closer to revolutionizing traffic control than previously thought.
