New research indicates mouse nose detects most pheromones governing reproduction
Scientists at Harvard University have found strong signs that the pheromones driving reproduction and fertility in mice are detected primarily by the nose -- not by the specialized vomeronasal system that many researchers had suspected of receiving and processing the bodily chemicals that govern mating behavior. The unexpected finding may settle an ongoing scientific debate by providing evidence that key reproductive behaviors in mice arise predominantly, if not exclusively, from olfactory input instead of input from the vomeronasal, visual or auditory senses.
The results, from a team led by Harvard biologist Catherine Dulac, appear on the web site of the journal Cell this week, and will be published in the journals Nov. 18 issue.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
