CT Scan Is No More Accurate than Ultrasound to Detect Kidney Stones

September 17, 2014
To diagnose painful kidney stones in hospital emergency rooms, CT scans are no better than less-often-used ultrasound exams, according to a clinical study conducted at 15 medical centers.

Our Microbes Are a Rich Source of Drugs, UCSF Researchers Discover

September 11, 2014
Bacteria that normally live in and upon us have genetic blueprints that enable them to make thousands of molecules that act like drugs, and some of these molecules might serve as the basis for new human therapeutics, according to UCSF researchers.

Malaria’s Clinical Symptoms Fade on Repeat Infections Due to Loss of Immune Cells, UCSF-Led Team Finds

August 27, 2014
Children who repeatedly become infected with malaria often experience no clinical symptoms with these subsequent infections, and a team led by UC San Francisco researchers has discovered that this might be due at least in part to a depletion of specific types of immune cells.

Do Gut Bacteria Rule Our Minds?

August 15, 2014
It sounds like science fiction, but it seems that bacteria within us – which outnumber our own cells about 100-fold – may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.

Single-Cell Analysis Holds Promise for Stem Cell and Cancer Research

August 06, 2014
UCSF researchers have identified cells’ unique features within the developing human brain, using the latest technologies for analyzing gene activity in individual cells, and have demonstrated that large-scale cell surveys can be done much more efficiently and cheaply than was previously thought possible.

Gene Behind Rare Birth Abnormality Is a Window on Evolution

July 30, 2014
A UCSF physician who treats birth defects affecting the face has teamed up with a European expert on animal evolution to create rodent teeth that harken back in evolutionary time.

Key to Aging Immune System Is Discovered

July 30, 2014
The immune system ages and weakens with time, making the elderly prone to life-threatening infection and other maladies, and a UCSF research team now has discovered a reason why.

Stem Cell Advance May Increase Efficiency of Tissue Regeneration

July 28, 2014
A new stem-cell discovery might one day lead to a more streamlined process for obtaining stem cells, which in turn could be used in the development of replacement tissue for failing body parts.

In Human Evolution, Changes in Skin’s Barrier Set Northern Europeans Apart

June 30, 2014
The popular idea that Northern Europeans developed light skin to absorb more UV light so they could make more vitamin D – vital for healthy bones and immune function – is questioned by UC San Francisco researchers in a new study.

A Diagnosis Just in Time

June 10, 2014
Joshua Osborn was fighting for his life against a mysterious ailment. With his options dwindling, a team at UCSF employed advanced DNA sequencing technology to track down the culprit.
