Chemists at the California Institute of Technology have succeeded in devising a new method for building carbohydrate molecules in a simple and straightforward way that requires very few steps. The new synthesis strategy should be of benefit to scientists in the areas of chemistry and biology and in the pharmaceutical industry.

PASADENA, Calif. — Oriented cell division is a fundamental process in developing organisms, whether you are a worm, a fruit fly--or a human. As an embryo begins to grow, cells divide again and again, from the single fertilized egg to the countless cells present at birth.

Astronomers have identified a new class of cosmic explosions that are more powerful than supernovae but considerably weaker than most gamma-ray bursts. The discovery strongly suggests a continuum between the two previously-known classes of explosions.

The Defense Advanced Research Projects Agency (DARPA) has awarded an $8 million, four-year, basic-research program grant to the California Institute of Technology to initiate research in photonics technologies. The technical focus of the effort will be on optofluidics, an exciting new research area based on the use of microfluidic devices to control optical processes, and which is expected to result in a new generation of small-scale, highly adaptable, and innovative optical devices.

One of the big problems in biology is keeping track of the proteins a cell makes, without having to kill the cell. Now, researchers from the California Institute of Technology have developed a general approach that measures protein production in living cells.

A common-sense notion among many Californians is that frequent small earthquakes allow a fault to slowly relieve accumulating strain, thereby making large earthquakes less likely. New research suggests that this is not the case for a long stretch of the San Andreas fault in Southern California.

Another milestone has been achieved in the quest to create prosthetic devices operated by brain activity. In the July 9 issue of the journal Science, California Institute of Technology neuroscientists Sam Musallam, Brian Corneil, Bradley Greger, Hans Scherberger, and Richard Andersen report on the Andersen lab's success in getting monkeys to move the cursor on a computer screen by merely thinking about a goal they would like to achieve, and assigning a value to the goal.

PASADENA, Calif. — The brain is a maddeningly complex organ for scientists to understand. No assumption can remain unchallenged, no given taken as a given.

Scientists who monitor Earth's reflectance by measuring the moon's "earthshine" have observed unexpectedly large climate fluctuations during the past two decades. By combining eight years of earthshine data with nearly twenty years of partially overlapping satellite cloud data, they have found a gradual decline in Earth's reflectance that became sharper in the last part of the 1990s, perhaps associated with the accelerated global warming in recent years. Surprisingly, the declining reflectance reversed completely in the past three years. Such changes, which are not understood, seem to be a natural variability of Earth's clouds.

You're driving along in your car and catch a glimpse of a green SUV out of the corner of your eye. A few seconds later, you glance over, and to your surprise discover that the SUV is actually brown.
