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...

How Nutrients Affect Plant Productivity Mapped By NASA
2012-11-02 06:46:06

NASA Jet Propulsion Laboratory A new analysis led by NASA's Jet Propulsion Laboratory, Pasadena, Calif., has estimated how much the growth of plants worldwide is limited by the amount of nutrients available in their soil. The maps produced from the research will be particularly useful in evaluating how much carbon dioxide Earth's ecosystems may be able to soak up as greenhouse gas levels increase. A research team led by JPL research scientist Josh Fisher used 19 years of data from NASA,...

Key To Controlling Fruit Ripening Could Be In The Functions Of Chloroplasts
2012-11-01 14:51:47

University of Leicester Biologists may have unearthed the potential to manipulate the functions of chloroplasts, the parts of plant cells responsible for photosynthesis. Researchers in the University of Leicester's Department of Biology discovered that chloroplasts are affected by the ubiquitin proteasome system (UPS) — a process which causes the breakdown of unwanted proteins in cells, previously thought to only act on central parts of the cell. As a result, the researchers...


Word of the Day
mundungus
  • A stinking tobacco.
  • Offal; waste animal product; organic matter unfit for consumption.
This word comes from the Spanish 'mondongo,' tripe, entrails.
