'A huge step forward in the safety screening of nanomaterials,' researchers say Engineered nanomaterials, prized for their unique semiconducting properties, are already prevalent in everyday consumer products – from sunscreens, cosmetics and paints to textiles and solar batteries – and economic forecasters are predicting the industry will grow into $1 trillion business in the next few years. But how safe are these materials? Because the semiconductor properties of...

If you throw a rubber balloon filled with water against a wall, it will spread out and deform on impact, while the same balloon filled with honey, which is more viscous, will deform much less. If the balloon's elastic rubber was stiffer, an even smaller change in shape would be observed. By simply analyzing how much a balloon changes shape upon hitting a wall, you can uncover information about its physical properties. Although cells are not simple sacks of fluid, they also contain...

In the fight against emerging public health threats, early diagnosis of infectious diseases is crucial. And in poor and remote areas of the globe where conventional medical tools like microscopes and cytometers are unavailable, rapid diagnostic tests, or RDTs, are helping to make disease screening quicker and simpler. RDTs are generally small strips on which blood or fluid samples are placed. Specific changes in the color of the strip, which usually occur within minutes, indicate the...

UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness and Alzheimer´s disease In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease. Published April 15 in the advance online edition of Nature Genetics, the study also uncovers new genes that may...

[ Watch the Video ] A team of researchers at the University of California, Los Angeles (UCLA) are building an advanced scientific instrument unlike any other ever built before, with the aim to study some of the oldest galaxies in the universe. The five-ton spectrometer, known as MOSFIRE (Multi-Object Spectrometer for Infra-Red Exploration), has been installed in the Keck I Telescope at the WM Keck Observatory in Hawaii where, once fully operational, it will receive infrared light that...

New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change. Droughts are worsening around the world, posing a great challenge to plants in all ecosystems, said Lawren Sack, a UCLA professor of ecology and evolutionary biology and senior author of the research. Scientists have debated for more than a century how to predict which species are most vulnerable. Sack and two members of his laboratory have made a fundamental...

New technique reveals another piece of spectrum's genetic architecture There is little argument among experts that autism spectrum disorders (ASD), complex developmental disabilities that vary widely in their severity, are caused by both genetic and environmental factors. Advances in genome sequencing now permit scientists to uncover specific mutations in DNA that are associated with ASD at unprecedented resolution. Such data are vital to understanding the genetic basis of the disorder....

Researchers at UCLA and New York University have developed a method to detect sequence differences in individual DNA molecules by taking nanoscopic pictures of the molecules themselves. The work is reported in the Journal of the Royal Society Interface. Using the approach they call "Direct Molecular Recognition," the UCLA and NYU researchers used nanoparticles to turn the DNA molecules into a form of molecular braille that can be read in the scale of nanometers, or one billionth of a...
