If you can imagine the straw in your soda can being a million times smaller and made of carbon, you pretty much have a mental picture of a carbon nanotube. Scientists have been making them at will for years, but have never gotten the nanotubes to suck up liquid metal to form tiny wires. In fact, conventional wisdom and hundreds of refereed papers say that such is not even possible.

An international team of scientists has announced a new breakthrough in understanding the molecular details of how signals move around in the human brain. The work is basic research, but could help pharmacologists design new drugs for treating a host of neurological disorders, as well as drugs for reducing alcohol and nicotine craving.

Humans and insects and pond scum-and all other living things on Earth-are constantly evolving. The tiny proteins these living things are built from are also evolving, accumulating mutations mostly one at a time over billions of years. But for reasons that hitherto have been a mystery, some proteins evolve quickly, while others take their sweet time-even when they reside in the same organism.

With gasoline prices hovering at $3 per gallon, probably few Americans need convincing that another energy crisis is imminent. But what precisely is to be done about our future energy needs is still a puzzle. There's talk about a "hydrogen economy," but hydrogen itself poses some formidable challenges.

"I am not a novelty. . . It is not amazing that girls are engineers-it's normal," says Victoria Loewer, a member of the class of 2005 at the California Institute of Technology. Loewer is referring to the fact that she is a member of the first all-female chemical engineering graduating class at Caltech, a significant milestone in the history of the Institute.

In two separate awards from the Ellison Medical Foundation, two scientists from the California Institute of Technology are taking a much more scholarly approach to the ravages of aging. Harry Gray, a chemist, has been awarded $970,000 to reveal the structure of a protein and a peptide that underlie two age-related diseases, Alzheimer's and Parkinson's, while biologist Alexander Varshavsky has been awarded $972,000 to conduct a systematic investigation of the genetics and biochemistry of aging.

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.
