Serena Lee aspires to increase our understanding of people living with “invisible disabilities.” Amy Stuyvesant wants to figure out how changes in hurricane activity are helping or hindering the forests of Puerto Rico.
Although their subjects of their research are unrelated, these two graduating seniors share a key distinction. Thanks to the Wasserman Undergraduate Scholars Program, they are pursuing high-level research that they expect to have an impact far beyond UCLA. (more…)
UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures.
“There is a growing recognition among biologists that climate change is affecting how species interact with one another, and that this is going to have very important consequences for the stability and functioning of ecosystems,” said the senior author of the research, Van Savage, an assistant professor of ecology and evolutionary biology and of biomathematics at UCLA. “However, there is still a very limited understanding of exactly what these changes will be. Our paper makes progress on this very important question.” (more…)
A UCLA-led study of adolescents receiving treatment for methamphetamine dependence has found that girls are more likely to continue using the drug during treatment than boys, suggesting that new approaches are needed for treating meth abuse among teen girls.
Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.
The creation of the first complete visual map of the telomerase enzyme, which is known to play a significant role in aging and most cancers, represents a breakthrough that could open up a host of new approaches to fighting disease, the researchers said. (more…)
UCLA researchers have used a brain-imaging tool and stroke risk assessment to identify signs of cognitive decline early on in individuals who don’t yet show symptoms of dementia.
The connection between stroke risk and cognitive decline has been well established by previous research. Individuals with higher stroke risk, as measured by factors like high blood pressure, have traditionally performed worse on tests of memory, attention and abstract reasoning. (more…)
Bedside Early-Warning System from IBM and Excel Medical Electronics Can Analyze Large Amounts of Data in Real Time to Predict Dangerous Changes in a Patient’s Condition
Armonk, N.Y. and Los Angeles, CA – 26 Mar 2013: IBM, and Excel Medical Electronics (EME) are collaborating with the UCLA Department of Neurosurgery in a study to test the effectiveness of a real-time alarm intended to predict rising brain pressure in patients with traumatic brain injuries. The experimental system uses big data analytics software developed by IBM Research and EME that analyzes in real-time streams of vital signs continuously collected from the bedside monitor to spot subtle changes in the patient’s pulse, blood and intracranial pressure, heart activity, and respiration, signaling that dangerous high-risk increases in brain pressure are on the way.

Bullet trains fuel real-estate booms, improve quality of life and create other unintended consequences by sharply reducing commute times from smaller cities to large megacities, economists from UCLA and China’s Tsinghua University observed in a new study in China. A similar dynamic, they said, could play out as California builds its own high-speed rail system. Because high-speed rail effectively brings cities closer together by reducing travel times, it allows people to enjoy many of the benefits of big cities while living in “second-tier” cities far from the pollution and congestion. By making second-tier cities attractive to those who would otherwise flock to global hubs, bullet trains could act as a safety valve for crowded megacities in the developing world and ease the effects of overpopulation, the study authors report.

This year’s unusually long and rocky flu season would be nothing compared to the pandemic that could occur if bird flu became highly contagious among humans, which is why UCLA researchers and their colleagues are creating new ways to predict where an outbreak could emerge.
“Using surveillance of influenza cases in humans and birds, we’ve come up with a technique to predict sites where these viruses could mix and generate a future pandemic,” said lead author Trevon Fuller, a UCLA postdoctoral research fellow at the Institute of the Environment and Sustainability’s Center for Tropical Research.
