New research by University of California, Los Angeles biologists could lead to predictions of which plant species will escape extinction from climate change. Droughts are worsening around the world, which poses a great challenge to plants in gardens and forests. Scientists have debated for more than a century how to predict which species are most vulnerable.
Researchers at New York University and the University of California, Los Angeles, developed a method to detect sequence difference in individual DNA molecules by taking nanoscopic pictures of molecules themselves. Using direct molecular recognition, the researchers used nanoparticles to turn DNA molecules into a form of molecular Braille that can be read in the scale of nanometers using an atomic force microscope.
University of California, Los Angeles researchers are now able to peer deep within the world's tiniest structures to create 3D images of individual atoms and their positions. Their research presents a new method for directly measuring the atomic structure of nanomaterials.
Researchers at the University of California, Los Angeles have used a standard LightScribe DVD optical drive to produce electrodes composed of an expanded network of graphene that shows excellent mechanical and electrical properties as well as exceptionally high surface area. These LSG supercapacitors demonstrate high-performance graphene-based electrochemical capacitors that maintain excellent electrochemical attributes under high mechanical stress.
Researchers from the University of California, Los Angeles have developed a new cell phone-based fluorescent imaging and sensing platform that can detect the presence of the bacterium Escherichia coli in food and water.
Researchers at University of California, Los Angeles report a unique way to enhance polymer solar cell performance by building a tandem structure device. The device's architecture has also proven to be widely applicable after the researchers adopted a new material provided by Sumitomo Chemical of Japan, increasing the power conversion efficiency from 8.62% to a new world record of 10.6%.
In a recent study, participants played a video game in which they learned the locations of stores in a virtual city. The study showed that they recalled the locations better also received a painless boost from tiny electrodes buried deep inside their brains. The finding may have uses in treating Alzheimer’s disease.
A team led by University of California, Los Angeles research astronomer Michael Rich has used a unique telescope to discover a previously unknown companion to the nearby galaxy NGC 4449, which is some 12.5 million light years from Earth. The newly discovered dwarf galaxy had escaped even the prying eyes of the Hubble Space Telescope.
University of California, Los Angeles researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt, using data collected from a fleet of orbiting spacecraft. In a paper, the team shows that the missing electrons are swept away from the planet by a tide of solar wind particles during periods of heightened solar activity.
Two women who are legally blind from two different incurable conditions appeared to gain some vision after receiving an experimental treatment using embryonic stem cells. Experts caution that discussion of clinical treatment is premature at this stage.
Minuscule amounts of ethanol, the type of alcohol found in alcoholic beverages, can more than double the life span of a tiny worm known as Caenorhabditis elegans , which is used frequently as a model in aging studies, University of California, Los Angeles biochemists report. The scientists said they find their discovery difficult to explain.
University of California, Los Angeles physicists have made nanomechanical measurements of unprecedented resolution on protein molecules. The new measurements are approximately 100 times higher in resolution than previous mechanical measurements, a nanotechnology feat which reveals an isolated protein molecule, surprisingly, is neither a solid nor a liquid.
Researchers from Aneeve Nanotechnologies, a start-up company at the University of California, Los Angeles' on-campus technology incubator at the California NanoSystems Institute, have used low-cost inkjet printing to fabricate the first circuits composed of fully printed back-gated and top-gated carbon nanotube–based electronics for use with OLED displays.
Researchers from University of California, Los Angeles' cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe the approach could be useful in about 40% of Caucasians with this malignancy.
Using a new microwave instrument based on the same principles as police radar guns, researchers from University of California, Los Angeles have finally observed very rapid changes in plasma turbulence in the DIII-D tokamak. These changes, which create and destroy surface flow eddies, are responsible for most of the heat losses in tokamak plasmas.
Data from a clinical trial involving University of California, Los Angeles researchers suggest that a new therapy may potentially serve as a "functional cure" for HIV/AIDS. The therapy, called SB-728-T, involves the modification of both copies of a patient's CCR5 gene, which encodes the major co-receptor used by HIV to infect immune system cells.
Is it possible to make valid climate predictions that go beyond weeks, months, even a year? University of California, Los Angeles atmospheric scientists report they have now made long-term climate forecasts that are among the best ever—predicting climate up to 16 months in advance, nearly twice the length of time previously achieved by climate scientists.
Lithium-ion batteries have become a leading energy source, and researchers are actively seeking ways to nudge their performance toward ever-higher levels. New analysis by the Massachusetts Institute of Technology and the University of California at Los Angeles has revealed why one widely used compound works particularly well as the material for one of these batteries' two electrodes.
Stem cell researchers at the University of California, Los Angeles have uncovered for the first time why adult human cardiac myocytes—specialized muscle cells in the heart—have lost their ability to proliferate, perhaps explaining why the human heart has little regenerative capacity.
Seventeen institutions officially joined forces last week to link computers, data and people from around the world to establish a single, virtual system, called XSEDE, that scientists can interactively use to conduct research. The National Science Foundation-funded effort will build on the high-performance computing ground broken by TeraGrid.
Researchers at the University of California, Los Angeles have developed a compact, lightweight, and cost-effective optofluidic platform that integrates imaging cytometry and florescent microscopy and can be attached to a cell phone. The resulting device can be used to rapidly image bodily fluids for cell counts or cell analysis.
Before forming multicellular biofilms, bacteria are able to move across surfaces and some do so in a jerky motion called “twitching”. Using a high-speed camera and a tracking algorithm, researchers at the University of California, Los Angeles, noticed that these bacteria also had the unique ability to "slingshot".
Archaea are among the oldest known life-forms, but remain mysterious even after biologists recognized these single-celled organisms as a distinct domain of life. Researchers using high-resolution electron microscopy, including the R&D 100 Award-winning FEI Titan S/TEM, have discovered minute granules that are extremely efficient at storing energy.
Researchers at UCLA have identified a new stem cell that participates in the repair of the lungs' large airways, which play a vital role in protecting the body from infectious agents and toxins in the environment.
Self-conscious about your age? Be careful where you spit. UCLA geneticists now can use saliva to reveal how old you are. The findings offer a myriad of potential applications. A newly patented test based on the research, for example, could offer crime-scene investigators a new forensic tool for pinpointing a suspect's age.
