The purpose is to help scientists understand how the complex activity of the brain gives rise to the complex behavior exhibited by animals, including humans.

Traces of water have been detected within the crystalline structure of mineral samples from the lunar highland upper crust obtained during the Apollo missions, according to a University of Michigan researcher and his colleagues.
The lunar highlands are thought to represent the original crust, crystallized from a magma ocean on a mostly molten early moon. The new findings indicate that the early moon was wet and that water there… read more

Astronomers have detected water in the atmosphere of a planet outside our solar system for the first time.
The discovery, announced today, means one of the most crucial elements for life as we know it can exist around planets orbiting other stars.

A slow, methodical transformation of the $400-billion-a-year water-management industry is currently in progress, and nanotechnology appears to be leading the way.
The promise of nanofiltration devices that “clean” polluted water, sifting out bacteria, viruses, heavy metals and organic material, is driving companies like Argonide and KX Industries, which developed technology used in Brita filters, to make nanotechnology-based filters for consumers. Two products incorporating nanotechnology are going to hit the… read more

Researchers have built a machine that solves mathematical problems using DNA as software and enzymes as hardware. A trillion such biomolecular machines – working at more than 99.8% accuracy – can fit into a drop of water. Computers with DNA input and output have been made before, but they involved a laborious series of reactions, each needing human supervision. The new automaton requires only the right molecular mix.

The LCROSS probe discovered the equivalent of a dozen 2-gallon buckets of water in the form of ice, in a crater at the lunar south pole.
Having that store of water on the moon could be a boon to possible future lunar camps. In addition to a source of drinking water, lunar water ice could be broken into its constituent hydrogen and oxygen atoms, ultimately to be used in… read more

The first scoop of soil analyzed by the analytical suite in NASA’s Curiosity rover reveals that fine materials on the surface of Mars contain several percent water by weight.
The results were published today in Science as one article in a five-paper special section on the Curiosity mission.
“One of the most exciting results from this very first solid sample ingested by Curiosity is the high… read more
Astrophysicists have found the first evidence of a water-rich rocky planetary body outside our solar system in its shattered remains orbiting a white dwarf.
A new study by scientists at the Universities of Warwick and Cambridge analyzed the dust and debris surrounding the white dwarf star GD61 170 light years away.
Using observations obtained with the Hubble Space Telescope and the large telescopes of… read more

The widespread availability of digital cameras and video-capable cellphones means that ubiquitous surveillance on the part of the little guys is moving, if anything, even faster than ubiquitous surveillance on the part of the big boys. And distribution tools like YouTube make it easier to get the footage to a large audience.

Researchers at MIT’s George R. Harrison Spectroscopy Lab have detected tiny twitches and vibrations in the live membranes of individual cells and neurons by using a powerful and noninvasive imaging technique. The technique could be used in the future to create three-dimensional images, illuminating even finer activities within living cells.
The method uses an optical technique based on interferometry: a laser beam passed through a sample is compared with… read more

Researchers conducted a series of experiments using fMRI to pinpoint the brain activity associated with introspection and that linked to sensory function.
They found that the brain assumes a robotic functionality when it has to concentrate all its efforts on a difficult, timed task — only becoming “human” again when it has the luxury of time.

MIT researchers have used two-photon microscopy to visualize chemical activity in individual brain cells of living animals.
The technique could be used to monitor cell activity in animal models of neurological disease or degeneration, or to test the effects of therapies in treating these conditions, or study plasticity, the ability of neurons and their connections to change in response to experience.

Los Alamos National Laboratory scientists have replaced the large magnets needed for MRI by using a combination of “dynamic nuclear polarization” to align carbon 13 nuclei before they are injected into the body and a new generation of superconducting quantum interference devices (SQUIDS) to pick up the signals used to reconstruct an image.
That should make ultra low field MRI images of metabolism in action even easier to make… read more

The MDKeeper, from Tadiran Spectralink, provides round-the-clock medical monitoring for at-risk patients.
It is worn like a watch and integrates various medical sensors, a Siemens GSM/GPRS radio module, and a built-in cellular speakerphone and processing unit to measure and transmit data to caregivers.
The MDKeeper measures vital signs, including pulse rate, cardiac rhythm (ECG or EKG), and blood oxygen levels. It can either store the data and transmit… read more
