How Do You Make a Greasy Protein?
Douglas Smith
Professor of Biochemistry Bil Clemons is focused on working out the structures of and biological processes associated with membrane proteins—assemblies of protein molecules that act as transport channels through the greasy lipid membrane that encapsulates a cell.

Progress for Paraplegics
Michael Rogers
Caltech engineers, who last year helped enable a paraplegic man to stand and move his legs voluntarily, have developed a new method to automate the system, which provides epidural electrical stimulation to people with spinal-cord injuries. This advancement could make the technology widely available to rehab clinics and thousands of patients worldwide.

How I Spent My Summer Vacation
Douglas Smith
Last summer, Caltech junior Julie Jester worked on a project that might one day partially counteract blindness caused by a deteriorating retina. Her job: to help Assistant Professor of Electrical Engineering Azita Emami and her graduate students create the communications link between a tiny camera and a novel wireless neural stimulator that can be surgically inserted into the eye.

The Physics of Going Viral
Kimm Fesenmaier

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.

Seeing Inside Tissue
Marcus Woo
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 Caltech, all of that may be possible in the not-so-distant future.

Understanding Bacterial Sensors
Kimm Fesenmaier

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.

Caltech Researchers Develop Gene Therapy to Boost Brain Repair for Demyelinating Diseases
Katie Neith

Researchers from Caltech now believe they have found a way to help the brain replace damaged myelin, a material that forms a protective cape around the axons of our nerve cells so that they can send signals quickly and efficiently.

Caltech Chemists Devise Chemical Reaction that Holds Promise for New Drug Development
Kimm Fesenmaier

A team of researchers at Caltech has devised a new method for making complex molecules. The reaction they have come up with could open up new avenues for the development of novel pharmaceuticals and natural products from chemotherapeutic compounds to bioactive plant materials such as morphine.

New Professor Uses Chemistry and Chemical Engineering to Make a Difference
Kimm Fesenmaier

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.

Biologists Deliver Neutralizing Antibodies that Protect Against HIV Infection in Mice
Katie Neith

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.
