| "Pacemaker for the brain" shows new potential |
| 2008-07-02 09:33:30 |
Deep brain stimulation, already approved for Parkinson's disease, might provide benefits for people suffering from psychiatric conditions such as obsessive-compulsive disorder, body dysmorphic disorder and depression. One or two electrodes implanted deep in the brain deliver mild electrical signals that reorganize the brain's electrical impulses.

| Super atoms turn the periodic table upside down |
| 2008-07-01 09:44:39 |
Researchers at Delft University of Technology (TU Delft) in The Netherlands have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) behave in the same way as individual atoms and have opened up a whole new branch of chemistry.

| Metals shape up with a little help from friends |
| 2008-06-30 09:19:03 |
For 5,000 years the only way to shape metal has been by the "heat and beat" technique. Even with modern nanotechnology, metalworking involves carving metals with electron beams or etching them with acid. Now Cornell researchers have developed a method to self-assemble metals into complex configurations with structural details about 100 times smaller than a bacterial cell by guiding metal particles into the desired form using soft polymers.

| 2008-06-27 20:09:26 |
In the late 19th century Gregor Mendel used peas to show that one copy of a gene (allele) is inherited from the mother and one from the father. In the progeny, the inherited genes are expressed at the right time and in the right place, but until recently, it was thought that although gene products could be modified during the life of the organism, the genes themselves were unchanged, except for random mutation.

By Mano Singham
In his book The Language Instinct, (1994) Steven Pinker pointed out two fundamental facts about human language that were used by linguist Noam Chomsky to develop his theory about how we learn language. The first is that each one of us is capable of producing brand new sentences never before uttered in the history of the universe.
