- Bio-inspired assembly of nanoparticle building blocks
11-27-2006 · EurekAlert!
Rice University chemists have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature's oldest known chemical innovations -- the self-assembly of lipid membranes that surround all living cells. The research appears in the Nov. 29 issue of the Journal of the American Chemical Society. It could help scientists design everything from better catalysts to potent new anti-cancer drugs.

- Technique controls nanoparticle size, makes large numbers
12-04-2007 · EurekAlert!
Pratim Biswas of Washington University in St. Louis conducts research on nanoparticles, which are the building blocks for nanotechnology. For the first time, Biswas has shown that he can independently control the size of the nanoparticles that he makes, keeping their other properties the same. He's also shown with his technique that the nanoparticles can be made in large quantities in scalable systems, opening up the possibility for more applications and different techniques.

- New findings blow a decade of assumptions out of the water
01-10-2007 · EurekAlert!
The Atlantic Ocean doesn't receive the mother lode of fixed nitrogen, the building block of life, after all. Instead, comparing fathom for fathom, the Pacific and Indian oceans experience twice the amount of nitrogen fixing as the Atlantic, say researchers in the January 11 issue of Nature. The title of an accompanying News and Views piece says it all, "Looking for N2 Fixation in all the Wrong Places."

- Nanoparticle Assembly Enters The Fast Lane
10-14-2006 · ScienceDaily
The speed of nanoparticle assembly can be accelerated with the assistance of DNA, a team of researchers at the US Department of Energy's Brookhaven National Laboratory recently found. Learning how to control the assembly of these miniscule particles into larger systems remains a major challenge for scientists. The Brookhaven results, published online on October 11, 2006, by the Journal of the American Chemical Society, are a step in that direction.

- A new wrinkle in evolution -- Man-made proteins
05-22-2007 · EurekAlert!
Nature, through the trial and error of evolution, has discovered a vast diversity of life from a primordial pool of building blocks. Inspired by this success, a new Biodesign Institute research team, led by John Chaput, is now trying to mimic the process of Darwinian evolution in the laboratory by evolving new proteins from scratch. Using new tricks of molecular biology, Chaput and co-workers have evolved several new proteins in a fraction of the three billion years it took nature.

- Building blocks of life formed on Mars
12-11-2007 · EurekAlert!
Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists at the Carnegie Institution's Geophysical Laboratory have shown for the first time that building blocks of life formed on Mars early in its history. Scientists have thought that organics in ALH 84001 was brought to Mars by meteorite impacts or originated from ancient Martian microbes.
