BBC News is reporting that European Southern Observatory group (ESO) is negotiating rights to a place in chili to build this monster. The main mirror would be 100m across, and the predicted resolution is 40 times better than hubble's. It will take 15 years to build and approx 1 billion euros.

An article in Nature Science Update talks about the recent finding of a pattern in ant cemeteries with the activator-inhibitor mechanism. It has long been established certain occurences in nature following Turing patterns, mathematical equations that accurately describe the structure of seemingly random events. The ants use of this in the patterns of burying their dead is the first example of such a pattern in higher organisms. Click read more to discuss this article. Click here for the Biology forum.

A new discovery implying to be a new "last resort" to security defenses on government computer systems and really important servers. The quote below is from Oracle Magazine "Those wishing to see a pilfered peripheral taken dead rather than alive may be encouraged by the work of a team of chemists at University Of California, San Diego. Researchers have created computer chips that can ruin the circuitry in anything from a spy plane to a cell phone. It involves applying an oxidizing chemical alled gadolinium nitrate to a permeable silicon chip. When an appropriate electric charge is applyed to the chemical--a detonation command sent to a laptop computer, for example--t…

Nanotechweb has an article describing a nanofabricated amperometrical detector that Cornell researchers are using to explore the process by which chemicals such as neurotransmitters are excreted from cells.

Wake Forest Univeristy researchers have a press release detailing an ion channel in the thalamus that increases in activity with moderate alcohol consumption, and is deactivated by higher amounts. This apparently explains why alcohol lets you sleep better at night, but disrupts sleep in the early morning. Click read more to discuss this article. Click here for the Neuroscience forum.

New Scientist is reporting that only keeping big fish can cause them to evolve into smaller fish in just four generations. . Bad news for us fisherman. Journal reference: Science (vol 297, p 94).

According to this article on Nature Science Update, scientists at MIT have constructed a prototype of a nitric oxide sensor using a polymer that is lined with Co ions that change the conductivity of the chain when NO bonds with them. NO causes blood vessels to dilate, and also is released by some CNS neurons death, which is associated with neurodegenerative disorders such as Alzheimer's. Detecting NO levels is useful for diagnosing this and various other diseases.
