Com a capacidade de formar qualquer tecido no corpo humano, as células-tronco pluripotentes induzidas, ou iPSCs, são essenciais ao trabalho do programa de Células-tronco da Universidade de San Diego no estudo de doenças e possíveis curas - mas como elas são produzidas? Esta breve cartilha resume as etapas básicas para originar estas células especiais.

Southern California Edison has a goal to reduce carbon-emissions 40% below 1990 levels by 2030, with an electric grid supplied by 80% carbon-free sources. Gary Barsley discusses SCE's pathway to clean power and electrification, reduced greenhouse gas emissions, and cleaning the power grid by decarbonizing the electric sector, electrifying the transportation sector, and electrifying buildings. SCE Emerging Products projects include assessing a number of new technologies to help achieve these important goals. Series: "Institute for Energy Efficiency" [Show ID: 35160]

Uma visão detalhada de um estudo conduzido pelo laboratório Alysson Muotri no Programa de Células-Tronco da UC San Diego, que encontrou o desenvolvimento de sinalização de redes complexas em organoides corticais humanos que parecem recapitular o desenvolvimento do cérebro fetal, oferecendo um modelo in vitro para estudar o desenvolvimento funcional de redes neuronais humanas.

Scientists, including from UC Davis, have successfully sequenced the coast redwood and giant sequoia genomes, completing the first major milestone of a five-year project to develop the tools necessary to study these forests’ genomic diversity. Over the past 150 years, 95 percent of the ancient coast redwood range and about one-third of the giant sequoia range have been logged. If diversity has declined, it could leave the redwoods vulnerable to drought, fire and other stressors related to climate change. Series: "UCTV Prime" [Show ID: 35170]

With the capacity to form any tissue in the human body, induced pluripotent stem cells, or iPSCs, are critical to the work of the UC San Diego Stem Cell program in studying disease and potential cures - but how are they made? This short primer outlines the basic steps to how these special cells are derived. Series: "Stem Cell Channel" [Show ID: 34455]

When heavy rain falls over the Indian Ocean, Southeast Asia and the eastern Pacific Ocean temperatures in California's Central Valley will reach 100 F (38 C) in 4 to 16 days, according to a collaborative research team from UC Davis, and the Asia-Pacific Economic Cooperation (APEC) Climate Center in Busan, South Korea. Researchers, including UC Davis Department of Land, Air and Water Resources professor Richard Grotjahn, were able to link the heat waves to the phases of a large, traveling atmospheric circulation pattern called the Madden-Julian Oscillation, or MJO.

Scott Kelly spent a year in the International Space Station while his identical twin Mark Kelly was on earth. UC San Diego and many institutions studied the mental, cardiovascular, immune, genetic, muscular, microbial, bone, and eye changes in both twins to see the effects of long-term space travel. Changes were troubling, so NASA plans several more long-term space flights that will focus on genetic changes, bone loss, loss of vision, brain swelling, and Nutrition. Michael G. Ziegler, MD, is Professor of Medicine Emeritus at UCSD. He has studied astronaut health since 1978. He chaired NASA’s yearly cardiovascular reviews, helped devise current astronaut protocols, and studied physiologic and genomic changes during the Year in Space study.   Series: "Osher UC San Diego Distinguished Lecture Series" [Health and Medicine] [Science] [Show ID: 35085]

Climate change and atmospheric rivers are bringing flood water to people’s homes, devastating communities. Entire towns are moving to escape rising waters, which is called managed retreat. Flood experts at UC Davis, including Nicholas Pinter, are visiting dozens of communities who have moved off the floodplain and to higher ground to avoid flooding.

Extremely sensitive to shifts in temperature, the ochre sea star is considered a “keystone species” for monitoring the effect of changing air and ocean temperatures on California’s marine life. Eric Sanford of the UC Davis Bodega Bay Marine Lab puts these beautiful creatures to the test, using their appetite for mussels as the yardstick. Series: "UCTV Prime cuts" [Science] [Show ID: 24211]
