Caltech and UCLA have launched highly productive collaborations in cancer research and other areas of biomedicine in recent years, frequently through the Caltech lab of Nobel Laureate and President Emeritus David Baltimore. Now, an endowment established by the Raymond and Beverly Sackler Foundation will strengthen the Caltech-UCLA partnership and advance the Baltimore lab’s interdisciplinary research into areas where mathematics and engineering converge with biology.

Caltech researchers have been able, for the first time, to watch viruses infecting individual bacteria by transferring their DNA, and to measure the rate at which that transfer occurs. Shedding light on the early stages of infection by this type of virus—a bacteriophage—the scientists have determined that it is the cells targeted for infection, rather than the amount of genetic material within the viruses themselves, that dictate how quickly the bacteriophage's DNA is transferred.

Imagine if doctors could perform surgery without ever having to cut through your skin. Or if they could diagnose cancer by seeing tumors inside the body with a procedure that is as simple as an ultrasound. Thanks to a technique developed by engineers at the California Institute of Technology (Caltech), all of that may be possible in the not-so-distant future.

Nearly all motile bacteria can sense and respond to their surroundings through a process called chemotaxis, which begins with proteins known as chemoreceptors. Now researchers at Caltech have built the first model that depicts precisely how chemoreceptors and the proteins around them are structured at the sensing tip of bacteria. Because chemotaxis plays a critical role in the first steps of bacterial infection, a better understanding of the process could pave the way for the development of new, more effective antibiotics.

Our bodies are full of tiny superheroes—antibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelin, a material that forms a protective cape around the axons of our nerve cells so that they can send signals quickly and efficiently. But myelin becomes damaged in demyelinating diseases like multiple sclerosis, leaving neurons without their sheaths. Researchers from Caltech now believe they have found a way to help the brain replace damaged myelin.

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.

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.

Over the past year, researchers at Caltech, and around the world, have been studying a group of potent antibodies that have the ability to neutralize HIV in the lab; their hope is that they may learn how to create a vaccine that makes antibodies with similar properties. Now, biologists at Caltech led by Nobel Laureate David Baltimore have taken one step closer to that goal: they have developed a way to deliver these antibodies to mice and, in so doing, have effectively protected them from HIV infection.

Using highly potent antibodies isolated from HIV-positive people, researchers have recently begun to identify ways to broadly neutralize the many possible subtypes of HIV. Now, a team led by biologists at Caltech has built upon one of these naturally occurring antibodies to create a stronger version they believe is a better candidate for clinical applications.

Mark E. Davis and David A. Tirrell of Caltech have been elected to the Institute of Medicine, an honor that is considered among the highest in the fields of health and medicine. Both Davis and Tirrell are already members of the National Academy of Sciences and the National Academy of Engineering, making them two of only 13 living individuals who have been elected to all three branches of the National Academies.
