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....

Early Cyanobacteria Samples Tested For Building Blocks Of Life

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...

Proliferation Favored Of Toxic Cyanobacteria From Global warming
2012-07-03 10:34:12

Cyanobacteria are among the most primitive living beings, aged over 3,500 million years old. These aquatic microorganisms helped to oxygenate the earth´atmosphere. At present their populations are increasing in size without stopping. It appears that global warming may be behind the rise in their numbers and may also lead toan increase in the amount of toxins produced by some of these populations. "Cyanobacteria love warm water, therefore an increase in temperature during this century...

An Arizona State University research team has developed a process that removes a key obstacle to producing lower-cost, renewable biofuels. The team has programmed a photosynthetic microbe to self-destruct, making the recovery of high-energy fats--and their biofuel byproducts--easier and potentially less costly. "The real costs involved in any biofuel production are harvesting the goodies and turning them into fuel," said Roy Curtiss, director of the Biodesign Institute's Center for Infectious...

Scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues at Creighton University have deciphered the highly unusual molecular structure of a naturally produced, ocean-based compound that is giving new understanding of the function of mammalian nerve cells.The findings are reported in the Aug. 27 online version of the journal Chemistry & Biology by principal co-investigators William Gerwick, professor of oceanography and pharmaceutical sciences at the Center...

Did life shape the early Earth, or did the early Earth shape life? The choice may be a false dichotomy, but living without light, water or oxygen gave the earliest microbes a limited menu to order their lives around. Astrobiology Magazine -- A geomicrobiologist at Washington University in St. Louis has proposed that evolution is the primary driving force in the early Earth's development rather than physical processes, such as plate tectonics. Carrine Blank, Ph.D., Washington University...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
