In eukaryotes — the group of organisms that include humans — a key to survival is the ability of certain proteins to quickly and accurately repair genetic errors that occur when DNA is replicated to make new cells. In a paper published in the December 23, 2011 issue of the journal Science, researchers at the Ludwig Institute for Cancer Research and the University of California, San Diego School of Medicine have solved part of the mystery of how these proteins do their job, a...

A team of researchers from the University of Notre Dame have demonstrated a novel DNA detection method that could prove suitable for many real-world applications. Physicists Carol Tanner and Steven Ruggiero led the team in the application of a new technique called laser transmission spectroscopy (LTS). LTS is capable of rapidly determining the size, shape and number of nanoparticles in suspension. In a new paper appearing in the international, peer-reviewed, open-access, online...

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies. To visualize the synthesis of...

Danish research team leads the way for future biodiversity monitoring using DNA traces in the environment to keep track of threatened wildlife — a lake water sample the size of a shot-glass can contain evidence of an entire lake fauna. Global biodiversity is plummeting while biologists are fighting to keep score and reliable monitoring of threatened animals remains a major challenge. The biologist toolset has changed little on this area for a hundred years - still relying on...

Image 1 - Backpacks, Not The Bombs Inside, Key To Finding DNA

Catching terrorists who detonate bombs may be easier by testing the containers that hide the bombs rather than the actual explosives, according to pioneering research led by Michigan State University. Currently, law enforcement labs tend to test for DNA on the exploded bomb fragments — but this has a low success rate, said David Foran, an MSU forensic biologist and lead investigator on the research project. Through the MSU-led study, researchers obtained DNA from eight backpacks...

The human genome and the endowments of genes in other animals and plants are like a deck of poker cards containing a "wild card" that in a genetic sense introduces an element of variety and surprise that has a key role in life. That's what scientists are describing in a review of more than 100 studies on the topic that appears in ACS Chemical Biology. Rahul Kohli and colleagues focus on cytosine, one of the four chemical "bases" that comprise the alphabet that the genetic material DNA uses...

Sky
2004-10-19 04:45:44

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...
