Research by scientists at the Broad Stem Cell Research Center shows that the cells carrying parents’ genes to a child are unprotected during part of the prenatal stage of development.

UCLA biologists have found that male aggression against potential rivals for females explains much of the phenomenon.

Using a tumor rejection antigen to identify stem cells could help ensure stem cell research studies are accurate.

California NanoSystems Institute researchers have imaged the atomic structures of three specific biological nanomachines, findings they hope advance work on antibiotics targeted toward specific pathogens.

New method for creating key motor neurons is more than five times more effective than previous efforts.

UCLA engineers and doctors developed a tool that can deliver nanoparticles, enzymes, antibodies and bacteria into cells thousands of times faster than current technology.

Stem cell gene therapy technique leads to production of healthy blood cells, could be used for other genetic diseases.

Life scientists have created an accurate new method to identify markers for many diseases — a significant step toward a new era of personalized medicine, tailored to each person’s DNA and RNA.

Screening travelers for fever on arrival has been criticized as ineffective, but the scientists found it can catch cases that screeners miss at departure.

A Google Glass app paired with a handheld device will allow users to quickly analyze the health of living plants without damaging them.

Darwin’s writings focused much more on species that had changed over time than on those that hadn’t. So how do scientists explain a species living for so long without evolving?

A team of life scientists has found part of the answer: The amount and intensity of striping in different zebra populations can be best predicted by temperature.

UCLA researchers found that although Prozac and Lexapro were thought to work the same way, the medications did not produce the same long-term changes in anxiety behavior.

The scientists resolved a dispute over whether a small population of black-headed squirrel monkeys, which are found only in an isolated part of Brazil, is a sub-species of another species or its own species.

Research could have broad, long-term impact in improving disease modeling and devising new therapies for patients.

The study sheds new light on why TM7 has thus far resisted scientific study and its role in the progression of periodontitis and other diseases.

A new research institute at UCLA may eventually provide doctors with tools to more accurately tailor therapies to patients, which would improve care and minimize side effects.

Biologists with the UCLA La Kretz Center for California Conservation Science recently went on a rescue mission to save endangered turtles that have become dehydrated, emaciated and stressed-out by the extended drought.

Scientists from UCLA, Harvard, Mass General and Stanford present strong evidence that a chemical modification on RNA plays a key role in determining embryonic stem cells’ ability to adopt different cellular identities.

From poultry to pies and sugar to soil, UC scientists are uncovering insights across the food spectrum that can make your holidays healthier, happier and more mindful.

The scientists created the largest protein ever that self-assembles into a molecular “cage.” The protein is hundreds of times smaller than a human cell.

Plants worldwide are more sensitive to drought than many scientists realized. The research may improve predictions of which plant species will survive climate change.

In a day-long event, renowned scientists will highlight and celebrate the monumental contributions of Wallace, at one time the most famous scientist in the world.

UCLA researchers have developed a standard to assess how closely stem cell culture conditions in the lab resemble a developing embryo.

A UCLA scientist was part of a team of that resolved an 80-year-old mystery about whether frogs in and around New York City were, in fact, their own unique species.
