The Internet is enough of a marvel that most people would never ask, "Is this really how we would build it if we could design it all today?" But asking that very question is the job of a broad-based team of Stanford researchers. Taking a nothing-is-sacred approach to better meet human communications needs, this month they are launching a new program called the Clean Slate Design for the Internet. They will present their ideas March 21 during a daylong workshop at the annual meeting of the Stanford Computer Forum.

"How should the Internet look in 15 years?" asks Nick McKeown, an associate professor of electrical engineering and computer science who is leading the effort.

Tiny tremors and temblors recently discovered in fault zones from California to Japan are generated by slow-moving earthquakes that may foreshadow catastrophic seismic events, according to scientists at Stanford University and the University of Tokyo.

In a study published in the March 15 issue of the journal Nature, the research team focused on weak seismic signals known as "non-volcanic tremor" and "low-frequency earthquakes," which seismologists say may be useful in forecasting the likelihood of potentially destructive mega-quakes of magnitude 8 or higher.

"Non-volcanic tremor is a weak shaking of the Earth that was discovered about five years ago in Japan," said Gregory C. Beroza, professor of geophysics at Stanford and co-author of the Nature study.

Instruments on NASA's Cassini spacecraft, part of the joint NASA/ESA/ASI Cassini-Huygens mission to Saturn and its moons, have found evidence for seas, likely filled with liquid methane or ethane, in the high northern latitudes of Saturn's moon Titan.

One such feature is larger than any of the Great Lakes of North America and is about the same size as several seas on Earth.

The problem of efficiently delivering drugs, especially those that are hydrophobic or water-repellant, to tumors or other disease sites has long challenged scientists to develop innovative delivery systems that keep these drugs intact until reaching their targets.

Now scientists in the University at Buffalo’s Institute for Lasers, Photonics and Biophotonics and Roswell Park Cancer Institute have developed an innovative solution in which the delivery system is the drug itself.

Purdue University chemical engineers have proposed a new environmentally friendly process for producing liquid fuels from plant matter - or biomass - potentially available from agricultural and forest waste, providing all of the fuel needed for "the entire U.S. transportation sector."

The new approach modifies conventional methods for producing liquid fuels from biomass by adding hydrogen from a "carbon-free" energy source, such as solar or nuclear power, during a step called gasification. Adding hydrogen during this step suppresses the formation of carbon dioxide and increases the efficiency of the process, making it possible to produce three times the volume of biofuels from the same quantity of biomass, said Rakesh Agrawal, Purdue's Winthrop E.

A team of UBC researchers has re-classified an ancient line of aquatic plants previously thought to be related to grasses and rushes. The discovery clarifies what may be one of the biggest misunderstandings in botanical history.

"It’s a classic case of mistaken identity," says Sean Graham, an associate professor and researcher with the UBC Botanical Garden and Centre for Plant Research in the Faculty of Land and Food Systems.
