UC Santa Barbara welcomes a new cohort of doctoral students from underrepresented backgrounds.  

For as long as she can remember, Lourdes Velazquez’s parents, who emigrated from Mexico to Los Angeles, made education a high priority. Employed in jobs that were both labor intensive and low paying, they taught their children the importance of excelling in school.

Taking their parents’ advice to heart, both Velazquez and her sister pursued advanced degrees. “We are the only two in our family that have pursued careers in STEM,” she said.

UCSB researchers create a device to help understand how cells communicate to form tissues and maintain integrity under loading.

Time-lapse of epithelial cells moving in response to shear force

As cells divide to form tissues and organs in multicell organisms, they move to where they belong, informed by a series of cues that scientists have yet to observe or fully understand.

In a potential game changer for the health care industry, a new cell phone app and lab kit now allow a smartphone to identify bacteria from patients anywhere in the world. With the new app, doctors will be able to diagnose diseases and prescribe the appropriate antibiotic within a one-hour office visit, meaning faster recovery — and lower treatment costs — for patients.

A Biophysical ‘Smoking Gun’

Scientists studying Alzheimer’s disease begin to unravel how the protein tau transitions from soluble liquid to solid fibrous tangle

While much about Alzheimer’s disease remains a mystery, scientists do know that part of the disease’s progression involves a normal protein called tau, aggregating to form ropelike inclusions within brain cells that eventually strangle the neurons. Yet how this protein transitions from its soluble liquid state to solid fibers has remained unknown — until now.

Why Antibiotics Fail

UCSB biologists correct a flaw in the way bacterial susceptibility to these drugs is tested

When a patient is prescribed the wrong antibiotic to treat a bacterial infection, it’s not necessarily the physician who is at fault. The current antibiotic assay — standardized in 1961 by the World Health Organization and used worldwide — is potentially flawed.
