Nutrient-rich Forests Absorb More Carbon
2014-04-15 14:53:42

IIASA The ability of forests to sequester carbon from the atmosphere depends on nutrients available in the forest soils, shows new research from an international team of researchers, including IIASA. The study, published in the journal Nature Climate Change, showed that forests growing in fertile soils with ample nutrients are able to sequester about 30% of the carbon that they take up during photosynthesis. In contrast, forests growing in nutrient-poor soils may retain only 6% of that...

By Karen McNulty Walsh, Brookhaven National Laboratory A new study published in the Proceedings of the National Academy of Sciences by scientists at the University of Queensland, Australia, overturns a long-held theory in plant science. Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory who are co-authors on this paper conducted critical radiotracer studies that support the new theory that plant sugars play a dominant role in regulating branching at...

By Carol Rasmussen, NASA Earth Science News Team Simply by breathing, humans have played a small part in the planet-wide balancing act called the carbon cycle throughout our existence. However, in the last few hundred years, we have taken a larger role. Our activities, such as fossil fuel burning and deforestation, are pushing the cycle out of its natural balance, adding more and more carbon dioxide to the atmosphere. Natural processes are working hard to keep the carbon cycle in...

April Flowers for redOrbit.com - Your Universe Online During the Northern Hemisphere's growing season, data returned from satellite sensors shows that the Midwest has more photosynthetic activity than any other region of the planet, according to a recent NASA report. School children are taught that plants convert light to energy through the process of photosynthesis. What is less known, however, is that chlorophyll also emits a fraction of the absorbed light as fluorescent glow, which...

Photosynthesis Measurements From Space

Carnegie Institution Plants convert energy from sunlight into chemical energy during a process called photosynthesis. This energy is passed on to humans and animals that eat the plants, and thus photosynthesis is the primary source of energy for all life on Earth. But the photosynthetic activity of various regions is changing due to human interaction with the environment, including climate change, which makes large-scale studies of photosynthetic activity of interest. New research from a...

Reimagining How Earth Emerged Out Of Ice Age
2014-03-19 14:15:38

Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature, say rapid erosion in mountain regions could explain why the Earth isn’t essentially still a snowball. Scientists have long believed that rocks pushed up to the surface by plate tectonics absorbed atmospheric carbon dioxide, and volcanic processes are what helps to emit this CO2. However, despite this theory and a variety of other hypotheses being put forward to balance the...

Amazon Inhales More Carbon Than It Emits
2014-03-18 20:28:30

NASA's Jet Propulsion Laboratory A new NASA-led study seven years in the making has confirmed that natural forests in the Amazon remove more carbon dioxide from the atmosphere than they emit, therefore reducing global warming. This finding resolves a long-standing debate about a key component of the overall carbon balance of the Amazon basin. The Amazon's carbon balance is a matter of life and death: living trees take carbon dioxide out of the air as they grow, and dead trees put the...

Nanotechnology Could Create Bionic Plants
2014-03-18 04:47:12

Lee Rannals for redOrbit.com - Your Universe Online A team of MIT researchers writing in the journal Nature Materials say they have discovered the first steps in a new field of science known as "plant nanobionics." The researchers found that they were able to boost a plant’s ability to capture light energy by 30 percent by embedding carbon nanotubes in the chloroplast. They were also able to use another type of carbon nanotube to modify the plants to detect nitric oxide. "Plants...
