Science: Auto-tuned

By | February 5, 2010

It's Carl Sagan like you've never heard him: his digitized, remixed voice sounds more like something emanating from a radio tuned to a pop music station than from a TV playing a public television documentary. Footage of the scientist in his award-winning PBS series linkurl:Cosmos;http://www.hulu.com/cosmos mingles with stunning computer animations depicting complex scientific concepts. This is all part of a novel project called linkurl:Symphony of Science,;http://www.symphonyofscience.com/index.

RNA repeats protect DNA

By | February 4, 2010

Repeat untranscribed DNA sequences are generally thought to be genetic junk at best, harmful at worst, but in ribosomes they are essential to repairing DNA damage, according to a study published this week in Science. Ribosomal protein complex Image: Wikimedia Commons Ribosomal DNA (rDNA) codes for the RNA that makes up a major component of ribosomes, the site of protein synthesis. Ribosomal RNA (rRNA) comprises 80% of the RNA found in a typical cell and is highly conserved from bacteria to hum

Mapping methylation

By | February 3, 2010

With the Human Genome Project largely complete, scientists are turning to variation in the epigenome and beginning to map chemical modifications of DNA that affect gene expression. Two recent studies that provide the first comprehensive maps of human DNA methylation -- one of the most commonly studied epigenetic modifications -- and a new initiative that aims to generate 1,000 more are a testament to this new focus in genetics research.

Quantum photosynthesis

By | February 3, 2010

Biologists have traditionally left quantum theory to physicists. But the complicated interactions between matter and energy predicted by quantum mechanics appears to play a role in photosynthesis, according to a study published this week in Nature -- affecting how energy from the sun makes its way to a cell's reaction centers before being converted to chemical energy that powers cellular functions.

Stimulus funds harbor hidden costs

By | February 2, 2010

When the American Recovery and Reinvestment Act (ARRA) doled out $10 billion to the National Institutes of Health and $3 billion to the National Science Foundation last year, many hailed it as a triumph for the US research enterprise. But the money, it turns out, comes with strings attached: keeping up with ARRA's administrative requirements is costing institutions thousands in increased overhead and may be compromising or delaying other initiatives and projects at the nation's leading research
