Super flat material could extend life of Moore's Law

Researchers could be fending off the demise of Moore's Law with the help of a new material that allows electrons to move from point A to point B faster. Engineers at the University of Utah discovered a new kind of flat semiconducting material made of tin monoxide that is only one-atom thick, allowing electrical charges to pass through it faster than silicon or other 3D materials.Read More

World's smallest beamsplitter paves way toward computing at the speed of light

Silicon photonics is an emerging technology that incorporates electronic circuits using photons of laser light rather than electrons to transmit, receive, and manipulate information. As such, a silicon photonic CPU could potentially process information at the speed of light – millions of times faster than computers available today. In a step towards this goal, engineers working at the University of Utah have developed an ultra-compact photonic beam-splitter so small that millions of these devices could fit on a single silicon chip.Read More

New study finds parallels between past and present climate change

There's an element of déjà vu in the most recent political news on climate change: UN-led talks, like the recent Lima summit, that end with disgruntled environmentalists and plans for yet another summit. At this point, our best hope is to mitigate the effects of global warming (which is occurring faster than previously thought) and, if possible, keep temperature rises to a maximum of 2° C (3.6° F). While the future of the planet looks uncertain with unpredictable climate patterns, U.S researchers looking to the past to gain a better understanding of modern climate change have found the rate of modern, human-caused global warming resembles that which occurred almost 56 million years ago much more closely than previously thought.Read More

Carbon nanotubes could find use in improved bomb detection device

Along with flame-retardant clothing, flexible supercapitors and a stronger alternative to carbon fiber, carbon nanotubes may soon have yet another application. Led by Prof. Ling Zang, a team of researchers at the University of Utah has integrated the tiny tubes of carbon atoms into a prototype explosives sensor. It can also detect illegal drugs and toxic chemicals such as nerve gas, reportedly doing so better than currently-used technologies. Read More

Dwarf galaxy suggests black holes may be more common than previously thought

Astronomers from the University of Utah, using the Gemini North telescope on Hawaii’s Mauna Kea and images captured by the Hubble Space Telescope, have discovered a dwarf galaxy that is the smallest ever recorded with a supermassive black hole at its center. The galaxy, M60-UCD1, has been found to contain a black hole with a mass equivalent to 21 million times that of our own sun and whose presence may suggest that such enormous black holes could be more common than previously thought.Read More

Scientists turn a US$40 needle into a high-quality 3D microscope

Beginning with a US$40 needle, researchers from the University of Utah have designed a microscope with the ability to generate miniaturized 3D images. The low-cost device is capable of producing images around 70 times smaller than the width of a human hair, a development that could offer new insights into how particular proteins in the brain function.

Human stem cell treatment gets mice with MS-like condition walking again

When scientists at the University of Utah injected human stem cells into mice disabled by a condition similar to multiple sclerosis, they expected the cells to be rejected by the animals' bodies. It turned out that the cells were indeed rejected, but not before they got the mice walking again. The unexpected finding could have major implications for human MS sufferers. Read More
