US National Academy of Sciences member and Stanford Professor Winslow R. Briggs will speak at the American Society of Plant Biologists (ASPB) annual meeting July 24, 2004 in Orlando, Florida about findings in his studies of how plants sense the direction of light.
Most casual observers have likely noticed that seedlings on a windowsill will grow toward the light. This phenomenon, known as phototropism, is a manifestation of a sensitive system plants have for detecting light. This light sensing system guides seedlings through the soil and has profound influences on their development during the critical stage of seedling establishment and later as the leaves adapt to changes in the light environment.
Briggss research group has discovered the two-member family of protein molecules that serves as the detector and decoder of the blue photons on which the seedling cues to determine the direction of light. The molecule, known as phototropin, is now being intensively studied because of its unique properties by chemists and biophysicists as well as plant biologists.

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...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
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...
