Got An Itch? New Study Shows How Scratching May Relieve It
http://feeds.sciencedaily.com/~r/sciencedaily/~3/m_Nin4gaBH0/090428112615.htm
Every dog and cat knows that scratching relieves an itch. But for ages, not even neuroscientists knew why. Now, a new study shows that scratching turns off activity in spinal cord nerves that transmit the itching sensation to the brain. The researchers hope eventually to learn just how the inhibition works.

More Than One Nanostring To Their Bow: Scientists Moving Closer To 'Artificial Noses'
http://feeds.sciencedaily.com/~r/sciencedaily/~3/Yk4hCGHJrHw/090423082919.htm
These days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. If a molecule docks onto one of the strings, then it becomes heavier, and its oscillations become measurably slower. However, such "nano-electromechanical systems", or NEMS, have been short of practical applications -- until now.

Is Biofuel Policy Harming European Biodiversity?
http://feeds.sciencedaily.com/~r/sciencedaily/~3/W3Vb-Ig2Euw/090424073907.htm
The EU promotes the production of biofuels and has set a target of 5.75% share of biofuels in the transport section for all EU Member States by 2010, and a target of 10% to be reached by 2020. Researchers have developed a new method of assessing biodiversity impacts resulting from changing land use due to the production of biofuel crops in Europe, distinguishing between arable (first generation) and woody (second-generation) crop types. The results indicate that more species might suffer from habitat losses rather than benefit from a doubled biofuel target, while abolishing the biofuel target would mainly have positive effects.

Using Combinatorial Libraries To Engineer Genetic Circuits Advances Synthetic Biology
http://feeds.sciencedaily.com/~r/sciencedaily/~3/YTQ4ZX90CBg/090422121902.htm
The process of selecting and blending genes to create artificial networks -- synthetic biology -- holds promise for many applications. But developing artificial networks takes time and is often frustrating. A research team has found a way to speed up the construction process by assembling a library of 20 versions of two gene promoters and a simple synthesis technique to create component libraries for synthetic library. This accessible method using combinatorial libraries removes the "tweaking" of gene network engineering.

No one doubts that mothers -- especially pregnant mothers -- are among the busiest people on earth. And while the benefits of exercise for these women and their developing fetuses are widely known, many expectant mothers do not exercise. A survey examining daily activities of moms-to-be will soon be released as part of a larger study looking at the effect of maternal exercise on fetal development. The results suggest, among other things, that exercising during pregnancy does not require "stealing" time from other activities.

Scorpions possess resistance to high temperatures and the ability to conserve water for long periods of time, and as a result thrive in hot and arid parts of the world. But is this global distribution also seen at a more local level? Biologists now show that this is indeed the case, even when European-like and African-like habitats were separated by no more than 100 meters.

http://feeds.sciencedaily.com/~r/sciencedaily/~3/KFssvp8Sjkw/090409134743.htm
What is the risk to high-rise buildings in Seattle from a giant earthquake? The Cascadia subduction zone is likely to produce the strongest shaking experienced in the lower 48 states. Although seismic activity in the Pacific Northwest has been relatively low in the past two centuries, there is a growing consensus that this fault zone ruptures in giant earthquakes (magnitude exceeding 9); the last rupture is inferred to have occurred in 1700.

Researchers have discovered that the genetic identity of a tumor cell is an incomplete predictor for how it will respond to certain treatments. In the case of one particular new and highly touted cancer treatment, genetically identical cancer cells responded differently. These variations resulted from random cell-to-cell differences, such as how many protein copies each cell had at the time of treatment. What's more, these non-genetic characteristics were passed on to subsequent generations of cells, establishing a transient heritability.

New 'Near-field' Radiation Therapy Promises Relief For Overheating Laptops
http://feeds.sciencedaily.com/~r/sciencedaily/~3/THnY3M01Fa8/090413103251.htm
Researchers have developed a way to release heat trapped inside billions of tiny semiconductor electronic circuits and channel it into the substrate, which is larger and can be more easily cooled. Their method exploits the electron scattering that occurs in non-suspended carbon nanotube transistors. This scattering causes a wave, or surface polariton, which is particularly strong in the near field zone above the substrate.

http://feeds.sciencedaily.com/~r/sciencedaily/~3/931KRuM-WlA/090408195557.htm
The North Atlantic Ocean is one of the Earth's tools to offset natural carbon dioxide emissions. In fact, the 'carbon sink' in the North Atlantic is the primary gate for carbon dioxide entering the global ocean and stores it for about 1500 years. The oceans have removed nearly 30 per cent of anthropogenic (man-made) emissions over the last 250 years. However, several recent studies show a dramatic decline in the North Atlantic Ocean's carbon sink.

You Wear Me Out: Thinking Of Others Causes Lapses In Our Self-control
http://feeds.sciencedaily.com/~r/sciencedaily/~3/VWwTbounrX8/090406192429.htm
Exerting self-control is exhausting. In fact, using self-control in one situation impairs our ability to use self-control in subsequent, even unrelated, situations. What about thinking of other people exerting self-control? A new study in Psychological Science suggests that our own self-control can be worn out simply by mentally simulating another person acting with self-control.

Cooperative Behavior Meshes With Evolutionary Theory
http://feeds.sciencedaily.com/~r/sciencedaily/~3/PvxxGIYkeRA/090406132056.htm
One of the questions raised by evolutionary theory is how cooperative behavior, which benefits other members of a species at a cost to the individual, came to exist. If only the fittest survive, genes for a behavior that benefits everybody in a population should not last and cooperative behavior should die out. Now researchers have used game theory to understand one solution yeast use to get around this problem.
