  • Tree biodiversity increases release of carbon from soils

    Soils play an important role in the carbon cycle, containing more than two thirds of the total carbon held in terrestrial ecosystems. Concern about climate change and rising CO2 levels is driving research to understand carbon cycling through soils. New research suggests that in tropical regions greater tree diversity increases soil respiration (the release of carbon) rates, but also improves ...

  • Latest FastOcean Sensor used at photosynthesis algorithm evaluation workshop

    Dr Kevin Oxborough participated in a workshop at the NIOZ labs in Yerseke, The Netherlands. The aim of the workshop was to validate a recently published algorithm (Oxborough et al. 2012, Limnology and Oceanography: Methods) that permits accurate estimates of the concentration of PSII reaction centres from active fluorometers. ...

  • NREL produces ethylene via photosynthesis

    Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have demonstrated a better way to use photosynthesis to produce ethylene, a breakthrough that could change the way materials, chemicals, and transportation fuels are made, and help clean the air. NREL scientists introduced a gene into a cyanobacterium and demonstrated that the organism remained stable ...

  • Women @ Energy: Lisa Utschig

    Solar energy conversion of water into environmentally clean fuels, such as hydrogen, offers one of the best long-term solutions for meeting future global energy needs. For over 50 years, the Photosynthesis Group at Argonne National Laboratory has been exploring nature’s inherent solar energy capture and conversion capabilities found in the photosynthetic machinery of plants, algae, ...

  • Pesticides and pharmaceuticals influence riverbed communities of microbes

    Changes in complex microbial communities known as ‘biofilms’ at the bottom of rivers can reveal the effects of pesticide and pharmaceutical pollution of river water, according to a recent study. Painkillers and anti-inflammatory drugs were found to have a significant effect on the structure and functioning of the biofilms. Human activities are contaminating surface waters with ...

  • Sunscreen identified as major cause of coral bleaching

    New research highlights the harmful effects of sunscreens on coral reefs. The ultra-violet (UV) filters, used to protect skin from the harmful effects of sun exposure, caused bleaching of coral reefs even at very low levels. In areas exposed to high levels of human activity, sunscreens may now be posing a significant risk to marine life. Coral reefs are among the most biologically productive and ...

  • Rainforest monitoring network deployed in Amazon

    Using open-access software and power saving technologies, researchers have developed an easily deployed, low-cost network for monitoring large areas of the Amazon rainforest. This Peruvian study shows that environmental information, such as soil moisture and rates of photosynthesis, can be recorded and uploaded to the internet without having to make repeated visits to remote areas. The Amazon ...

  • LGR Launches Unique Gas Analyzer for Quantitative Detection of Carbonyl Sulfide (OCS) Anywhere
