11-28-2007 · European Space Agency (ESA)
ESA's Venus Express has revealed Venus as never before. For the first time, scientists are able to investigate from the top of its atmosphere, down nearly to the surface. They have shown it to be a planet of surprises that may once have been more Earth-like, and still is, to a certain extent.

- Tracking alien turbulences with Venus Express
04-03-2007 · European Space Agency (ESA)
New images and data from ESA's mission to Venus provide new insights into the turbulent and noxious atmosphere of Earth's sister planet. What causes violent winds and turbulences? Is the surface topography playing a role in the complex global dynamics of the atmosphere? Venus Express is on the case.

- 'Hot' oxygen atoms on titanium dioxide motivated by more than just temperature
02-08-2008 · EurekAlert!
Catalysts typically break down an oxygen molecule into two identical atoms that behave the same. But on a titanium oxide catalyst, the two atoms of a split oxygen molecule act differently: one fills a vacant spot on the catalytic surface and the other acquires extra energy and can move away. If the finding turns out to be important to reactivity, it might also be useful in hydrogen production or to break down pollutants.

- Brewing a blast-less fertilizer
09-05-2007 · EurekAlert!
Down in the green, rolling hills and farmlands of Kentucky, Darrell Taulbee can often be found mixing up a batch of his homegrown fertilizer. But Taulbee isn't looking to grow a better Big Boy or distill a smoother bourbon, he tells us. Funded by the University of Kentucky and the Homeland Security's Science & Technology Directorate, he sets his sights on something far more sinister. Darrell Taulbee putters with this stuff to make sure another Oklahoma bombing never happens again.

- Salk scientists identify key nerve navigation pathway
11-21-2007 · EurekAlert!
Newly-launched nerve cells in a growing embryo must chart their course to distant destinations, and many of the means they use to navigate have yet to surface. Scientists at the Salk Institute for Biological Studies have recovered a key signal that guides motor neurons -- the nascent cells that extend from the spinal cord and must find their way down the length of limbs such as arms, wings and legs.

- Brain cells work differently than previously thought
08-19-2007 · EurekAlert!
Scientists know that information travels between brain cells along hair-like extensions called axons. For the first time, researchers have found that axons don't just transmit information -- they can turn the signal up or down with the right stimulation. This finding may help scientists develop treatments for psychiatric disorders such as depression and schizophrenia in which it is thought that different parts of the brain do not communicate correctly with each other.
