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...

How Mountains And Rivers Make Life Possible
2014-03-14 14:47:09

Stanford University Favorable conditions for life on Earth are enabled in part by the natural shuttling of carbon dioxide from the planet's atmosphere to its rocky interior and back again. Now Stanford scientists have devised a pair of math equations that better describe how topography, rock compositions and the movement of water through a landscape affects this vital recycling process. Scientists have long suspected that the so-called the geologic carbon cycle is responsible for...

Looking To Geology To Find Answers Of How Life On Earth Originated
2014-03-13 10:20:59

[ Watch the Video: The Origins of Life on Earth ] Brett Smith for redOrbit.com - Your Universe Online By simulating a geologic precursor of cell metabolism, a team of British and American scientists have taken an important step toward understanding how life arose on Earth. Their work is published in a new paper in the journal Astrobiology. “What we are trying to do is to bridge the gap between the geological processes of the early Earth and the emergence of biological life on this...

Researchers Identify Key Intermediate Steps In Artificial Photosynthesis Reaction
2014-03-04 11:03:17

Lynn Yarris, Berkeley Lab Artificial photosynthesis, in which we emulate the process used by nature to capture energy from the sun and convert it into electrochemical energy, is expected to be a major asset in any sustainable energy portfolio for the future. Artificial photosynthesis offers the promise of producing liquid fuels that are renewable and can be used without exacerbating global climate change. A key to realizing commercial-scale artificial photosynthesis technology is the...

Cancer cells have long been known to have higher rates of the energy-generating metabolic pathway known as glycolysis. This enhanced glycolysis, a phenomenon known as the Warburg effect, is thought to allow cancer cells to survive the oxygen-deficient conditions they experience in the center of solid tumors. A study in The Journal of Cell Biology reveals how damaged cells normally switch off glycolysis as they shut down and shows that defects in this process may contribute to the early stages...

Ups And Downs Of Early Atmospheric Oxygen

Iqbal Pittalwala - University of California - Riverside UC Riverside research team challenges conventional view of a simple two-step rise in early oxygen on Earth; study suggests instead dynamic oxygen concentrations that rose and fell over billions of years A team of biogeochemists at the University of California, Riverside, give us a nontraditional way of thinking about the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth...

A Glowing Plant Is A Sign Of Health
2014-02-12 15:16:02

ESA Radiant skin is considered a sign of good health in humans, but plants also glow when they are well. A potential new ESA satellite could use this fluorescence to track the health and productivity of vegetation worldwide. The Florescence Explorer, or FLEX for short, is a candidate for ESA’s eighth Earth Explorer. It aims to provide global maps of vegetation fluorescence, which can be used to work out actual photosynthetic activity. This information would improve our...

Photosynthesis-Activating Protein Likely Predates Oxygen On Earth
2014-02-09 08:21:12

[ Watch the Video: Photosynthesis Older Than Oxygen ] redOrbit Staff & Wire Reports – Your Universe Online Thioredoxin, a protein essential to the process of photosynthesis in plants, likely developed on Earth long before oxygen ever became available, according to a study published in last week’s early online edition of the Proceedings of the National Academy of Sciences. In the study, an international team of researchers analyzing methane-producing microbes found that...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
