Michael Crumbliss for RedOrbit.com This week new research was published that points to seagrasses as a solution to climate change. Seagrass can store up to twice the carbon of the world´s terrestrial forests. The paper, "Seagrass Ecosystems as a Globally Significant Carbon Stock," is the first global analysis of carbon stored in seagrasses and was published in the journal Nature Geoscience.  The research was led by James Fourqurean of Florida International University, in...

Researchers Measure Carbon In The Arctic Ocean

Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean´s carbon cycle–the pathway through which carbon enters and is used by the marine ecosystem. It will also offer an important point of reference for determining how those levels of carbon...

Ancient plants grown in state-of-the-art growth chambers recreating environmental conditions from more than 400 million years ago have shown scientists from the University of Sheffield how soil dwelling fungi played a crucial role in the evolution of plants. This ground breaking work provides fundamental knowledge of how plants colonized the land before roots evolved and the co-evolution of one of the most ancient relationships, between fungi and early plants that played a founding role in...

Nature's Mathematical Formula For Survival

[ Watch the Video ] Geometric patterns link structure to function in leaves The structure and delivery of nutrients is provided by the Vascular system in the leaf. With the use of fluorescent dye and time-lapse photography, details of nature's mathematical formula for survival begin to emerge. Mother Nature is tough to beat when it comes to optimizing form with function. Marcelo Magnasco, a mathematical physicist at Rockefeller University in New York, says "When looking at the...

Concordia physicists modify battery-like enzyme to produce carbon-neutral energy New research at Concordia University is bringing us one step closer to clean energy. It is possible to extend the length of time a battery-like enzyme can store energy from seconds to hours, a study published in the Journal of The American Chemical Society shows. Concordia Associate Professor László Kálmán – along with his colleagues in the...

Plants breathe through stomata Plant leaves are protected from drying out by an airtight wax layer. They breathe and release water through microscopic pores called stomata. Every year 40% of atmospheric CO2 and twice the volume of water found in our atmosphere pass through these pores. This means that stomata are not only important for plant development but also for our climate! It's no surprise then that these pores appear to be strictly regulated by plants. Stomata react extremely...

Imagine being able to use electricity to power your car – even if it's not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity. Today, electrical energy generated by various methods is still difficult to store efficiently. Chemical batteries, hydraulic pumping and water splitting suffer from low energy-density...

Life deep in the seabed proceeds very slowly. But the slow-growing bacteria living many meters beneath the seafloor play an important role in the global storage of organic carbon and have a long-term effect on climate. A team of scientists from Aarhus University (Denmark) and the University of Rhode Island have developed a new method for measuring this slow life deep down in the seabed. According to URI Oceanography Professor Arthur Spivack, the relative abundance of amino acids that are...

The major difference between plant and animal cells is the photosynthetic process, which converts light energy into chemical energy. When light isn't available, energy is generated by breaking down carbohydrates and sugars, just as it is in animal and some bacterial cells. Two cellular organelles are responsible for these two processes: the chloroplasts for photosynthesis and the mitochondria for sugar breakdown. New research from Carnegie's Eva Nowack and Arthur Grossman has opened a window...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
