First DNA Molecule Constructed from Mostly Synthetic Components

ScienceDaily is reporting that Japanese chemists have created the world's first DNA molecule comprised of almost entirely artificial components. The breakthrough could lead to advances in both medicine and technology, possibly utilizing the massive storage capacity of DNA. "In the new study, Masahiko Inouye and colleagues point out that scientists have tried for years to develop artificial versions of DNA in order to extend its amazing information storage capabilities. As the genetic blueprint of all life forms, DNA uses the same set of four basic building blocks, known as bases, to code for a variety of proteins used in cell functioning and development. Until now, scientists have only been able to craft DNA molecules with one or a few artificial parts, including certain bases.

Zetasizer Nano helps establish size independence in DNA driven nanoparticle structuring

A research team led by Dr Oleg Gang at the Brookhaven Center for Functional Nanomaterials (CFN) in New York is using the Zetasizer Nano particle characterization system from Malvern Instruments in ground-breaking work that has demonstrated successful DNA-guided formation of ordered 3-D crystalline structures. DNA's natural ability to self-assemble according to pre-programmed genetic codes within its pairing bases makes it the perfect architectural device for construction of novel crystalline structures. The ability to engineer such 3-D structures enables the production of functional materials that take advantage of the unique properties that may exist at the nanoscale - for example, enhanced magnetism, improved catalytic activity, or new optical properties.

Next iPod Nano Sighting, Plus That iPhone Nano Rumor

Colleague Cliff Edwards, next door on Tech Beat reports having seen a device he theorizes is a next-generation iPod nano, sporting a touch screen. (Sorry no pictures.) He argues pretty convincingly that its a likely change for the fall. I’ve been thinking that the transition to the current nano model, nicknamed “little fatty� had happened too recently for it to be time for a major change to the nano. But then there’s the issue of consistent look and feel. If the iPod touch is now the flagship of the iPod family, and it looks like an iPhone, then shouldn’t the nano also look more like an iPhone as well, and as such sport a touch screen? Makes perfect sense to me.

DNA Heritage Success in Patent Battle Helps Keep Genealogy DNA Test Prices Low

PRNewswire/ -- DNA Heritage has recently overcome patent claims held by a competitor which would have severely restricted the use of DNA testing and databases that allow families around the world to match and connect up through their DNA. The patent covers the use of surnames and Y-chromosomes to establish a family connection. The UK Intellectual Property Office (UK IPO) has now rendered a formal opinion stating that the relevant claims are all invalid.

Nano sculptures In Gold

If someone is charged up, the colour of their face might change, but they don't immediately pull off one of their arms, only to reattach it as a third leg. With some molecules, however, the situation is quite different - for example, in a gold cluster with seven atoms. In a charged state, the atoms arrange themselves differently than when they are uncharged. This was discovered by scientists at the Fritz Haber Institute of the Max Planck Society in Berlin, the Steacie Institute for Molecular Sciences in Canada and by scientists working with the FELIX free electron laser at the FOM Institute in Rijnhuizen in the Netherlands. The researchers ingeniously combined an infrared spectrometer and a mass spectrometer to show the structures of uncharged gold nano particles for the first time.

Coupling Across a DNA Helical Turn Yields a Hybrid DNA/Organic Catenane Doubly Tailed with Functional Termini

We describe the synthesis of a hybrid DNA/organic macrocycle that is prepared by formation of an amide linkage across one full turn of DNA. Formation of a catenane proved that the linkage crossed a turn rather than running along the phosphodiester backbone contour. The product, a doubly tailed catenane, contains 5′- and 3′-termini that can be functionalized further or used to incorporate the catenane structure into other DNA assemblies.

Apple iPod Nano (PRODUCT) Red Special Edition

(Review) - As if the iPod Nano didn’t already have a number of flavors, Apple had to release a special edition just for kicks. You can think of the new iPod Nano (PRODUCT) Red as the U2 version of the Nano series. We can’t say we dislike the new (PRODUCT) Red, since it’s quite vibrant and rather unique, yet minimal. Also, the features and specifications are exactly the same as other Nano players, except the (PRODUCT) Red is made for a good cause, which we will get to later in the review.
