Using corncob waste as a starting material, researchers have created carbon briquettes with complex nanopores capable of storing natural gas at an unprecedented density of 180 times their own volume and at one seventh the pressure of conventional natural gas tanks.
Science doesn’t always happen at a lab bench. For University of Toronto Mississauga physicist Kent Moore, it happens while strapped into a four-point harness, flying head-on into hurricane-force winds off the southern tip of Greenland.
New research aimed at understanding the link between carbon dioxide emissions and climate change in boreal systems has found clear links between both Spring and Fall temperature changes and carbon uptake/loss. Dr Kevin Robert Gurney, assistant professor in the Earth & Atmospheric Science/Agronomy at Purdue University and Associate Director of the Purdue Climate Change Research Center, presented these results at the “Is a Warmer Arctic Adding Carbon Dioxide to the Atmosphere” session of American Association for the Advancement of Science meeting in San Francisco, CA on December 17th.
At a 9 am press conference at the American Association for the Advancement of Science Annual Meeting (AAAS) on February 18th, an international team of leading fisheries economists, biologists, and ecologists will call for the abolition of government fuel subsidies that keep deep-sea fishing vessels moving to deeper waters.
"Industrial fisheries are now going thousands of miles, thousands of feet deep and catching things that live hundreds of years in the process - in the least protected place on Earth," says Elliott Norse of the Marine Conservation Biology Institute.
A scientific panel revealed today that rising global demand for healthy seafood has exceeded wild capture fisheries' ability to provide all fish meals demanded by consumers. Aquaculture -- or the farming of seafood -- is helping to fill the gap between sustainable wild supplies and the public demand for seafood. Research unveiled at the AAAS Annual Meeting demonstrated the enormous potential for sustainable growth of healthy farmed seafood production, notably through advancements in feed efficiency and the ability to expand production in marine environments.
When glaciologist Lonnie Thompson returns to Peru's Qori Kalis glacier early this summer, he expects to find that half of the ice he saw during his visit there last year has vanished.
What troubles him the most is his recent observations that suggest that the entire glacier may likely be gone within the next five years, providing possibly the clearest evidence so far of global climate change.
Despite the icy cold and darkness, beneath the frozen surface of the sea in Antarctica thrives a rich and complex array of plants and animals. But what will happen to all those creatures if global warming reduces the ice-cover, as is predicted for coming decades?
Since the spring of 2005, scientists working for the Institute of Systems Biology and Ecology (ISBE) from the Czech Academy of Sciences have been focusing on research aimed at designing a physically-based algorithm to scale spectral and spatial data on vegetation, which is relevant to the development of the Sentinel-2 mission.Map of total chlorophyll content (Cab)generated from the hyperspectral airborne AISA Eagle sensor (pixel-size 0.4 m) acquired in 2004 over Norwegian spruce at the Bily Kriz research site in the Czech Republic.
According to a recent paper published by MBARI geologists and their colleagues, methane gas bubbling through seafloor sediments has created hundreds of low hills on the floor of the Arctic Ocean.
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location. They accomplished this feat by completely converting the light pulse into matter that travels between the two locations and is subsequently changed back to light.
