The ever-increasing threat from "superbugs" -- strains of pathogenic bacteria that are impervious to the antibiotics that subdued their predecessor generations -- has forced the medical community to look for bactericidal weapons outside the realm of traditional drugs. One promising candidate is the antimicrobial peptide (AMP), one of Mother Nature's lesser-known defenses against infections, that...

The Conferee Networking committee is pleased to announce its annual Call for Topics for Conferee Networking sessions, which will take place during Pittcon 2014 at McCormick Place, Chicago, IL, March 2 to 6, 2014. These two-hour sessions provide a unique networking opportunity for attendees with similar interests to meet and resolve problems, discuss new techniques, or brainstorm new ideas in an informal setting.
NASA scientists have established a new way to use satellites to measure what's occurring inside plants at a cellular level. Plants grow and thrive through photosynthesis, a process that converts sunlight into energy. During photosynthesis, plants emit what is called fluorescence
The Orbital Sciences L-1011 aircraft takes off from Vandenberg Air Force Base in California at 9:30 p.m. EDT on June 27, 2013, headed over the Pacific Ocean to release the Pegasus XL rocket carrying NASA's Interface Region Imaging Spectrograph, or IRIS, solar observatory.
In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could be completely inactive. That's because, in biology, "left" and "right" molecular designs are crucial: Living organisms are made only from left-handed amino acids. So telling the...
Technicians and engineers at Vandenberg Air Force Base in California mate the Pegasus XL rocket with the Interface Region Imaging Spectrograph, or IRIS, solar observatory to the Orbital Sciences L-1011 carrier aircraft. IRIS will open a new window of discovery by tracing the flow of energy and plasma through the chromospheres and transition region into the sun’s corona using spectrometry and imaging.
Let's all fist bump: Spiral galaxies like our own Milky Way appear to be much larger and more massive than previously believed, according to a study by researchers using the Hubble Space Telescope. CU-Boulder Prof. John Stocke said new observations with Hubble's $70 million Cosmic Origins Spectrograph, or COS, show that normal spiral galaxies are surrounded by halos of gas that can extend to over 1 million light-years in diameter.
Since the discovery of the Van Allen radiation belts in in the Earth's upper atmosphere in 1958, space scientists have believed that these belts consisted of two doughnut-shaped rings of highly charged particles — an inner ring of high-energy electrons and energetic positive ions, and an outer ring of high-energy electrons.
What would you do with a camera that can take a picture of something and tell you how new it is? If you’re Berkeley Lab scientists Katherine Louie, Ben Bowen, Jian-Hua Mao and Trent Northen, you use it to gain a better understanding of the ever-changing world of metabolites, the molecules that drive life-sustaining chemical transformations within cells.
he Program Committee is currently accepting abstracts for contributed oral, poster and eposter presentations for the Pittcon 2014 Technical Program in areas such as, but not limited to, analytical chemistry, applied spectroscopy, life science, bioanalysis, food science, nanotechnology, environmental science and pharmaceutical.
Detecting greenhouse gases in the atmosphere could soon become far easier with the help of an innovative technique* developed by a team at the National Institute of Standards and Technology (NIST), where scientists have overcome an issue preventing the effective use of lasers to rapidly scan samples.
When it comes to examining the surface of rocks on Mars with a high-powered laser, five is a magic number for LANL postdoctoral researcher Nina Lanza. Lanza described how the laser-shooting ChemCam instrument aboard the Curiosity rover currently searching the surface of Mars for signs of habitability has shown what appears to be a common feature on the surface of some very different Martian rocks.
Pittcon 2013, The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy Exposition, takes place March 17-21, 2013, at the Pennsylvania Convention Center, Philadelphia, PA. It will include 1,011 exhibitors (count as of March 1, 2013) displaying products and services used by the scientific community in industrial, academic, and government labs.
A multi-university research team has used a new spectroscopic method to gain a key insight into how light is emitted from layered nanomaterials and other thin films. The technique, called energy-momentum spectroscopy, enables researchers to look at the light emerging from a thin film and determine whether it is coming from emitters oriented along the plane of the film or from emitters oriented perpendicular to the film.
Behind locked doors, in a lab built like a bomb shelter, Perry Gerakines makes something ordinary yet truly alien: ice. This isn't the ice of snowflakes or ice cubes. No, this ice needs such intense cold and low pressure to form that the right conditions rarely, if ever, occur naturally on Earth. And when Gerakines makes the ice, he must keep the layer so microscopically thin it is dwarfed by a...
Researchers have detected significant amounts of water in the samples of the lunar highland upper crust obtained during the Apollo missions. The lunar highlands are thought to represent the original crust, crystallized from a mostly molten early Moon that is called the lunar magma ocean
Scientists are celebrating their recent success on the path to understanding what makes the fiber that spiders spin — weight for weight — at least five times as strong as piano wire. They have found a way to obtain a wide variety of elastic properties of the silk of several intact spiders’ webs using a sophisticated but non-invasive laser light scattering technique
Two scientists from the Department of Energy's Pacific Northwest National Laboratory have been named Fellows of the American Physical Society. Wayne Hess and Hongfei Wang were recognized for their "exceptional contributions to the physics enterprise." APS fellows are nominated...
12/10/12 - A team of astrobiology researchers — including two from Rensselaer Polytechnic Institute — will use a series of nighttime flights on an airborne observatory to search newly born stars for the presence of precursors to life.
Four Pacific Northwest National Laboratory scientists have been elected fellows of the American Association for the Advancement of Science for their efforts to advance science or its applications. The PNNL honorees and the AAAS sections that elected them are: Nigel Browning,...
The most likely source of the water locked inside soils on the moon's surface is the constant stream of charged particles from the sun known as the solar wind, a University of Michigan researcher and his colleagues have concluded
By using an ordinary green laser pointer, the kind commonly found in offices and college lecture halls, an Israeli research team has developed a new and highly portable Raman spectrometer that can detect extremely minute traces of hazardous chemicals in real time
Nano-ribbons of silicon configured so the atoms resemble chicken wire could hold the key to ultrahigh density data storage and information processing systems of the future.
