When a small bug landed on Dr. Igor Siwanowicz's hand and began "fiercely digging its mandibles" into his skin, he didn't swat it away. Instead, he captured and began taking photomicrographs. To his surprise, the image took first place in the 2011 Nikon Small World competition.
Scientists at the University of California, San Diego have developed what they believe to be the first polymeric material that is sensitive to biologically benign levels of near infrared (NRI) irradiation, enabling the material to disassemble in a highly controlled fashion.
Scientists have created a working cloaking device out of sheets of carbon nanotubes that takes advantage of one of nature's most bizarre phenomenon, the mirage. The invention relies on the thermal capabilities of nanotubes and works best underwater.
Carbon sequestration is a potential solution for reducing greenhouse gases that contribute to climate change, but its scientific challenges are complex. Analytical tools are needed that provide information about the mineral-fluid interactions of carbon dioxide at the molecular level. As part of Pacific Northwest National Laboratory's Carbon Sequestration Initiative, a team of EMSL and PNNL researchers developed and patented such a tool.
The U.S.- and Singapore-based creators of the low-cost I-slate electronic tablet are preparing for full-scale production now that a yearlong series of tests has shown that the device is an effective learning tool for Indian children.
CRAIC Technologies' Lightswitch by CRAIC is an optical multiplexer for the ultraviolet, visible, and NIR regions. This unit is designed to attach to an open photoport to add more capabilities to the microscope or microspectrophotometer to which it is attached.
Scientists have known for more than 100 years that the universe is expanding, but in 1990s three physicists determined that this expansion is accelerating. The surprising finding, which suggests the cosmos will eventually freeze to ice, has earned the 2011 Nobel Prize in physics.
Kin-Tek Laboratories Inc.'s Trace Source Permeation Tubes use a mixture of reagent-grade nitric and sulfuric acids as the analyte source. The sulphuric acid binds the water, reducing water emission to negligible levels.
Imaging sensor chips that form the heart of built-in cameras helped engineers at the California Institute of Technology create a "smart" petri dish. The ePetri is a compact, lens-free microscopy imaging platform that does away with the need for bulky microscopes and significantly reduces labor for the researcher.
The Deepwater Horizon spill contained a large amount of natural gas, which immediately became food for bacteria. In a new study, scientists explain how they used DNA to identify the microbes present in the Gulf of Mexico during the spill, and how temperature played a role the microbes' ability to consume the gas.
A team of researchers from the University of California, Davis has accomplished the MacGyver-esque task of using everyday iPhones to accomplish high-quality medical-quality imaging and chemical detection. The key is adding spectrometry to the smart phone’s optics.
Two heat-loving fungi, often found in composts that self-ignite without flame or spark, could soon have new vocations. The complete genetic makeup of Myceliophthora thermophila and Thielavia terrestris has been decoded by an international group of scientists. The findings may lead to the faster and greener development of biomass-based fuels, chemicals, and other industrial materials.
With new cutting-edge technology aimed at providing amputees with robotic limbs, a Tel Aviv University researcher has successfully implanted a robotic cerebellum into the skull of a rodent with brain damage, restoring its capacity for movement.
At the end of the last Ice Age, atmospheric carbon dioxide levels rose rapidly as the planet warmed; scientists have long hypothesized that the source was carbon dioxide released from the deep ocean. But a new study using detailed radiocarbon dating of foraminifera found in a sediment core from the Gorda Ridge off Oregon reveals that the Northeast Pacific was not an important reservoir of carbon during glacial times.
From monsoons in Mumbai to windstorms in Seattle, weather patterns around the world are influenced by the MJO, or Madden-Julian Oscillation, a 30- to 60-day atmospheric wave that is poorly understood. Pacific Northwest National Laboratory and the National Center for Atmospheric Research have joined forces to model MJO and better understand how tropical weather affects global climate.
