Researchers at University of California San Diego School of Medicine report that they have successfully created spinal cord neural stem cells (NSCs) from human pluripotent stem cells (hPSCs) that differentiate into a diverse population of cells capable of dispersing throughout the spinal cord and can be maintained for long periods of time.
Early Earth was a hot, gaseous, dusty and dynamic planet with an atmosphere and an ocean. Then its surface cooled and stabilized enough for clouds, landmasses and early life to form about four billion years ago, during what’s called the isotopic age of rocks, or the Archean Period. Atmospheric chemical byproducts from that time traveled through the air and deposited inside the planet’s oldest rock, recording life’s earliest activities like photosynthesis and oxygen production.
Sulfur isotopes can serve as tracers of atmospheric oxygen and new data collected from the present-day atmosphere in China by an international team of researchers, led by the University of California San Diego, indicate remarkable similarity to the isotopic footprint found in ancient rocks. This opens up new interpretations of the Archean Period’s sulfur isotope sedimentary signature—a proxy for the origins and evolution of atmospheric oxygen and early life on Earth.
For the first time, researchers at University of California San Diego School of Medicine and Imperial College London, with international collaborators, have determined that Kawasaki disease (KD) can be accurately diagnosed on the basis of the pattern of host gene expression in whole blood. The finding could lead to a diagnostic blood test to distinguish KD from other infectious and inflammatory conditions.
New research in climate science indicates that extreme events, such as heat waves, the collapse of major ice sheets, and mass extinctions are becoming dramatically more probable. Though cuts in rising emissions appear unlikely with the stalled 2015 Paris agreement, University of California San Diego scientists argue that new developments present an opportunity to shift the politics around climate change.
For the first time, scientists can make a strong case that no one is exempt from the extreme and immediate risks posed by a warming world.
UC San Diego and UCLA led the University of California system during the 2017 fiscal year in the number of commercial startups based on campus inventions, according to a report released this week by the University of California’s Office of the President.
UC San Diego Health and Rancho Family Medical Group (RFMG) announced today that they have entered into an exclusive strategic affiliation designed to enhance the delivery of high-quality care to patients in Southwest Riverside County.
