Thymus Cells Transform Into Skin Cells in Swiss Laboratory
----------------------------------------------------------ScienceDaily (Aug. 19, 2010) — Taking one type of cell and transforming it into another type is now possible. Cells taken from the thymus have been transformed into skin cells -- a discovery that may have important ramifications for the field of organ regeneration. The findings, published on the 19th of August in Nature, show that these stem cells change their genetic make-up according to their environment to contribute to the long-term functioning of the skin, even producing hair for up to a year after implantation.
Gain and Loss in Optimistic Versus Pessimistic Brains---------------------------------------------------------
ScienceDaily (Aug. 9, 2010) — Our belief as to whether we will likely succeed or fail at a given task -- and the consequences of winning or losing -- directly affects the levels of neural effort put forth in movement-planning circuits in the human cortex, according to a new brain-imaging study by neuroscientists at the California Institute of Technology (Caltech).
Image of New Antibiotic in Action Opens Up New Opportunities to Combat Antibacterial Resistance
----------------------------------------------------------
ScienceDaily (Aug. 6, 2010) — New detailed pictures reveal how a new type of experimental antibiotic can kill bacteria that are already resistant to existing treatments. The findings could ultimately help scientists to develop new antibiotics to tackle the bacteria responsible for many hospital and community-acquired infections.

ScienceDaily (Aug. 4, 2010) — A team of Harvard physicists led by Mikhail D. Lukin has achieved the first-ever quantum entanglement of photons and solid-state materials. The work marks a key advance toward practical quantum networks, as the first experimental demonstration of a means by which solid-state quantum bits, or "qubits," can communicate with one another over long distances.
Genome of Ancient Sponge Reveals Origins of First Animals, Cancer----------------------------------------------------------
ScienceDaily (Aug. 4, 2010) — The sponge, which was not recognized as an animal until the 19th century, is now the simplest and most ancient group of animals to have their genome sequenced.
Iron Oxide Nanoparticles Becoming Tools for Brain Tumor Imaging and Treatment
---------------------------------------------------------------
ScienceDaily (Aug. 3, 2010) — Tiny particles of iron oxide could become tools for simultaneous tumor imaging and treatment, because of their magnetic properties and toxic effects against brain cancer cells. In mice, researchers from Emory University School of Medicine have demonstrated how these particles can deliver antibodies to implanted brain tumors, while enhancing tumor visibility via magnetic resonance imaging (MRI).

ScienceDaily (Aug. 2, 2010) — A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology, say the Stanford engineers who discovered it and proved that it works. The process, called "photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.
