New 'stamping' process to pattern biomolecules at high resolution developed Posted: 21 Sep 2012 06:26 AM PDT Researchers have used rubber stamps to pattern biomolecules in a new way. Instead of using molecular "inks" transferred from the stamps to substrates, the new method removes molecules already in place on the surface, by having them react with the stamp surface. In the new "subtractive" printing process, the rubber stamps selectively remove patterns from molecular monolayers with much higher pattern fidelity than with conventional soft lithography and can be used over and over again.

New turtle tracking technique may aid efforts to save loggerhead Posted: 21 Sep 2012 06:26 AM PDT The old adage "you are what you eat" is helping scientists better understand the threatened loggerhead turtle, which is the primary nester on Central Florida's beaches.

Mosquito virus could lead to new vaccines and drugs Posted: 21 Sep 2012 06:26 AM PDT The newly discovered Eilat virus is closely related to some of the world's most dangerous pathogens but incapable of infecting non-insect hosts. This attribute could make the virus a uniquely useful tool for studying the viruses responsible for chikungunya, Venezuelan equine encephalitis, western equine encephalitis and eastern equine encephalitis. In addition, the researchers say, Eilat could also aid in the development of new vaccines, therapies and diagnostic techniques.

Giving lithium to those who need it Posted: 21 Sep 2012 06:25 AM PDT Lithium is a 'gold standard' drug for treating bipolar disorder, however not everyone responds in the same way. New research finds that this is true at the levels of gene activation, especially in the activation or repression of genes which alter the level the apoptosis (programmed cell death). Most notably BCL2, known to be important for the therapeutic effects of lithium, did not increase in non-responders. This can be tested in the blood of patients within four weeks of treatment.

Ultra fast optical amplifier: Silicon and erbium on one chip for the first time Posted: 21 Sep 2012 06:25 AM PDT Within optical microchips, light finds its way through channels, waveguides, made of silicon. Light from a glass fiber, for example, is led through a structure of optical channels with splitters and couplers. Silicon is the workhorse for this, but it is still passive conduction of light, with some losses as well. To be able to amplify the signal, or even to include a light source on the chip, extra steps are necessary. Other types of semiconductors, like Gallium Arsenide, are an option. But materials doped with the rare earth material erbium have good amplification properties as well.

Squeeze light 'till it hurts' on a quantum scale: Researchers push the boundaries on ultra-precise measurement Posted: 21 Sep 2012 05:35 AM PDT Physicists has pushed the boundaries on ultra-precise measurement by harnessing quantum light waves in a new way. It is one thing to be able to measure spectacularly small distances using "squeezed" light, but it is now possible to do this even while the target is moving around.

Twenty-three nuclear power plants found to be in tsunami risk areas Posted: 21 Sep 2012 05:32 AM PDT Tsunamis are synonymous with the destruction of cities, and homes and since the Japanese coast was devastated in March 2011 we now know that they cause nuclear disaster, endanger the safety of the population and pollute the environment. As such phenomena are still difficult to predict, a team of scientists has assessed "potentially dangerous" areas that are home to completed nuclear plants or those under construction.

New challenges for ex-Olympians Posted: 21 Sep 2012 05:32 AM PDT When elite-level athletes retire, they often struggle to adapt to their new lives. When finding that the characteristics that were valuable in sport are not equally useful in 'ordinary' life, they often start experiencing disorientation, depression, self-doubt or even illness.

Brain: Multiple contacts are key to synapse formation Posted: 21 Sep 2012 05:31 AM PDT Multiple synaptic contacts between nerve cells facilitate the creation of a new contact, as neuroscientists report. An integral mechanism of memory foundation is the formation of additional contacts between neurons in the brain. However, until now it was not known what conditions lead to the development of such synapses and how they are stabilized once created. By studying mathematical models, the scientists found a simple explanation for how and when synapses form -- or disappear -- in the brain.

'Foreign' proteins are also implicated in Alzheimer's disease Posted: 21 Sep 2012 05:31 AM PDT Neurodegenerative diseases such as Alzheimer's or Parkinson's are characterised by the loss of nerve cells and the deposition of proteins in the brain tissue. Scientists have now demonstrated that Alzheimer's disease does not just – as previously believed – involve the proteins that are attributed to Alzheimer's, but instead the condition can involve a mixture of interacting proteins from different neurodegenerative diseases.

Unprecedented cancer 'Moon Shots Program': Effort sets new bar for eradicating cancer Posted: 21 Sep 2012 05:28 AM PDT The University of Texas MD Anderson Cancer Center announces the launch of the Moon Shots Program, an unprecedented effort to dramatically accelerate the pace of converting scientific discoveries into clinical advances that reduce cancer deaths.
