  • 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 ...

  • New insights into plant uptake of carbonyl sulfide aid global carbon cycle model

    In a study published in Science on 14 November, NOAA and CIRES scientists and colleagues show that carbonyl sulfide (COS), a trace gas consumed by plants, provides quantitative evidence that gradients of COS during the growing season are controlled by plant uptake during photosynthesis. This in turn provides an independent measure of plant photosynthesis rates crucial for carbon cycle modeling, a ...

  • Idea could lead to cheap solar cells using plant waste

    Remote communities could eventually make their own solar cells using waste vegetation, thanks to a design developed by researchers in Switzerland and the United States. The technology is inspired by photosynthesis. In plant cells, sunlight separates electrical charges with almost 100 per cent ...

  • A new leaf turns in carbon science

    A new insight into global photosynthesis, the chemical process governing how ocean and land plants absorb and release carbon dioxide, has been revealed in research that will assist scientists to more accurately assess future climate change. In a paper published today in Nature, a team of US, Dutch and Australian scientists have estimated that the global rate of photosynthesis, the ...

  • Oldest trees are overlooked in the fight against climate change

    A new analysis shows that the role of old-growth or ancient forests in removing carbon from the atmosphere has been underestimated. The authors of the study suggest that such forests must be protected to aid the fight against climate change. Scientists have revealed that forests that are centuries old continue to remove carbon dioxide from the atmosphere. Up to now, the consensus was that these ...

  • Ozone, nitrogen change the way rising carbon dioxide affects earth`s water

    Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. The researchers concluded that models of climate change may be underestimating how much water is likely to ...

  • New way to split water into hydrogen and oxygen developed

    The design of efficient systems for splitting water into hydrogen and oxygen, driven by sunlight is among the most important challenges facing science today, underpinning the long term potential of hydrogen as a clean, sustainable fuel. But man-made systems that exist today are very inefficient and often require additional use of sacrificial chemical agents. In this context, it is important to ...

  • Climate scientists` warning on air quality

    Actions to improve air quality and reduce climate change need to be linked claim scientists attending an annual United Nations conference on climate change in Poland this week. By the 2090s close to one-fifth of the world's population will be exposed to ozone levels well above the World Health Organization recommended safe-health level. Met Office Hadley Centre models project year-round ...


  • 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

    Los Gatos Research (LGR), the leader in precision trace gas analyzers, has launched an ultra-sensitive analyzer that provides real-time, direct and automated measurement of carbonyl sulfide (OCS or COS) in ambient air samples with parts-per-trillion precision and at rates as fast as 10 Hz. This new OCS Analyzer also provides simultaneous measurements of carbon monoxide (CO), carbon dioxide (CO2) ...

  • Chelsea Technologies Group holding workshop on innovative fluorescence technique at Water, Wastewater and Environmental Monitoring Conference (7-8 Nov)

  • Viruses harnessed to split water

    MIT team’s biologically based system taps the power of sunlight directly, with the aim of turning water into hydrogen fuel. A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth. In this case, the team used a modified virus as a kind of biological scaffold that can assemble the ...

  • Secretary Chu: China`s clean energy successes represent a new `Sputnik Moment` for America

    In a speech at the National Press Club, U.S Energy Secretary Steven Chu said that the success of China and other countries in clean energy industries represents a new "Sputnik Moment" for the United States, and requires a similar mobilization of America's innovation machine so that we can compete in the global race for the jobs of the future. Secretary Chu outlined efforts underway at the ...

  • BBA announces Algae Biodiesel research Progress

    Algae are tiny, plantlike organisms that grow naturally and are composed of carbohydrates, proteins and plant oil. They are extremely diverse and can be found in most habitats of the world including fresh and sea water, salt lakes, soil, snow and on surfaces such as rocks and the bark of trees. Their ranges from about 1 μm (nanoplankton) to more than 40 m (kelp), with many microalgae used for ...

  • Long term data for monitoring climate change

    Nearly 30 years of sampling data demonstrate that rural locations can be used to monitor greenhouse gases (GHGs), even in a densely populated continent such as Europe. The data have been used to explore how vegetation affects GHG emissions. Urban and industrial settings are unsuitable for measuring global trends in levels of GHGs as there are many local sources of emissions which can affect the ...
