In the 1970s, Caltech researcher Aron Kuppermann found additional computer resources in an unlikely place: a local religious organization. In the same spirit of creativity, Caltech researchers today have also found ways to practice resourceful computing.

When scientists think about the replication of information in chemistry, they usually have in mind something akin to what happens in living organisms when DNA gets copied: a double-stranded molecule that contains sequence information makes two new copies of the molecule. But researchers at the California Institute of Technology (Caltech) have now shown that a different mechanism can also be used to copy sequence information.

With $6 million of funding from the Gordon and Betty Moore Foundation, Caltech has established the Chemistry of Cellular Signaling Center. The new center will build on the Institute's successes at the interface of chemistry and biology, and will focus on determining how complex systems of molecules interact to create the pathways that regulate the lives of cells and allow them to respond to their environments.

With the Mars Science Laboratory (MSL) well on its way to Mars, the newest members of its science team have been announced. Two Caltech professors—Kenneth Farley and Bethany Ehlmann—are among 18 researchers who have been selected as funded participating scientists on the mission.

Our genetic information is under constant attack. Luckily, repair proteins are typically hard at work, locating and fixing damaged DNA. Over the past decade, Caltech chemist Jacqueline Barton has been exploring a model that describes how repair proteins might work together in this scouting mission to efficiently home in on lesions or mismatches within the DNA. Recent results from her lab support the model.

David Tirrell, the Ross McCollum-William H. Corcoran Professor and professor of chemistry and chemical engineering at Caltech, has been appointed director of the Beckman Institute.

A team of researchers at  Caltech has devised a new method for making complex molecules. The reaction they have come up with should enable chemists to synthesize new varieties of a whole subclass of organic compounds called nitrogen-containing heterocycles, thus opening up new avenues for the development of novel pharmaceuticals and natural products ranging from chemotherapeutic compounds to bioactive plant materials such as morphine.

Scientists have long seen evidence of social behavior among many species of animals. Dolphins frolic together, lions live in packs, and hornets construct nests that can house a large number of the insects. And, right under our feet, it appears that roundworms are having their own little gatherings in the soil. Until recently, it was unknown how the worms communicate to one another when it's time to come together. Now, however, researchers from Caltech have identified, for the first time, the chemical signals that promote aggregation.

It has been 25 years since scientists discovered the first high-temperature superconductors—copper oxides, or cuprates, that conduct electricity without a shred of resistance at temperatures much higher than other superconducting metals. Now, two Caltech chemists have developed a hypothesis to explain the strange behavior of these materials, while also pointing the way to a method for making even higher-temperature superconductors.

Rustem Ismagilov, the new John W. and Herberta M. Miles Professor of Chemistry and Chemical Engineering at Caltech, believes in the ability of science and technology to address significant societal problems—from the spread of HIV and drug resistance to bacterial imbalances in the gut.

André Hoelz, Caltech's newest assistant professor of chemistry, endeavors to fully characterize the nuclear pore complex, a cellular component made up of many copies of about 30 different proteins—perhaps 1,000 proteins in all and 10 million atoms—which forms a transport channel in the membrane of the nuclear envelope. Hoelz calls the complex "the gatekeeper of the nucleus."
