Chemists at the University of California, Davis, have engineered blue-green algae to grow chemical precursors for fuels and plastics -- the first step in replacing fossil fuels as raw materials for the chemical industry. "Most chemical feedstocks come from petroleum and natural gas, and we need other sources," said Shota Atsumi, assistant professor of chemistry at UC Davis and lead author on the study published Jan. 7 in the Proceedings of the National Academy of Sciences. The U.S....

Photosynthesis - The Last Link In The Chain
2013-01-05 05:45:05

April Flowers for redOrbit.com - Your Universe Online For almost three decades, scientists have tried to identify a particular enzyme involved in regulating electron transport during photosynthesis. Now, a research team from Ludwig Maximilians Universitat (LMU) has found the missing link, which turns out to be not so new. All life on Earth is sustained by photosynthesis, a sunlight powered process that provides energy-rich compounds and the molecular oxygen that higher organisms depend...

The Evolution Of Grass Photosynthesis
2012-12-26 05:22:06

Brett Smith for redOrbit.com - Your Universe Online In examining the differences in photosynthetic activity among certain types of grasses, researchers from Brown University found that some plants are positioned to take evolutionary advantage of certain situations. According to a report in the Proceedings of the National Academy of Sciences, Brown researcher Pascal-Antoine Christin spent two years analyzing the cellular anatomy of 157 living species of two different grass clades, BEP...

Women with higher circulating carotenoid levels are at a reduced risk of breast cancer according to a study published December 6 in the Journal of the National Cancer Institute Carotenoids, which are micronutrients found in fruits and vegetables, have been found to have anticarcinogenic properties. Previous experimental studies have shown that carotenoids inhibit the tumor progression and reduce proliferation of estrogen receptor—positive (ER+) and estrogen receptor—negative...

Forest Ecosystems Impacted By Climate Change
2012-11-29 12:04:30

April Flowers for redOrbit.com - Your Universe Online Off the southern coast of California, the fog rolls in over Santa Cruz Island coating the needles of the Bishop pines with moisture. Water drops form on the needles and roll down to fall to the forest floor, happening over and over on every needle of every tree. The forest ecosystem depends on this fog drip to stay alive. Bishop pines are thought to have proliferated all along the West Coast of the US and Mexico thousands of years...

Algae Held Captive And Their Genes Stolen In Crime Of Evolution
2012-11-28 15:38:41

University of Melbourne Microscopic animals held algae captive and stole their genes for energy production, thereby evolving into a new and more powerful species many millions of years ago reveals a new study published today in the journal Nature. The results reveal a 'missing link' in evolution because the tiny animal thieves (protozoa) couldn't completely hide all evidence of the captive algae, and have been effectively frozen in time and caught in the act by genetic sequencing....

Process For Chameleon-like Changes In World's Most Abundant Phytoplankton Uncovered
2012-11-27 10:36:33

Indiana University IU seeks patent for discovery with implications for health care, climate change research An international team of biologists led by Indiana University's David M. Kehoe has identified both the enzyme and molecular mechanism critical for controlling a chameleon-like process that allows one of the world's most abundant ocean phytoplankton, once known as blue-green algae, to maximize light harvesting for photosynthesis. Responsible for contributing about 20 percent of...

Early Cyanobacteria Samples Tested For Building Blocks Of Life
2012-11-13 05:53:25

April Flowers for redOrbit.com - Your Universe Online Before DNA became the Earth's primary genetic material over 3.5 million years ago, scientists believe forms of life used RNA to encode genetic instructions. What came before RNA, though? A research team from Weber State University and the Stockholm University think the answer might be N-(2-aminoethyl)glycine AEG, a small molecule that when linked forms a hypothetical backbone for peptide nucleic acids. Scientists hypothesize that...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
