Pittcon, a leading laboratory science and technical innovation showcase, attracts thousands of conferees from 90 countries visit each year to evaluate new products and technologies, formulate purchase decisions, and form valuable business connections. Conferee registration, is now open for Pittcon 2014, to be held March 2-6, at McCormick Place South, Chicago, Ill.

What if computer screens had glasses instead of the people staring at the monitors? That concept is not too far afield from technology being developed by UC Berkeley computer and vision scientists. They are developing computer algorithms to compensate for an individual’s visual impairment, and creating vision-correcting displays that enable users to see text and images clearly without wearing eyeglasses or contact lenses.
A team of international researchers has discovered a new type of cool burning flames that could lead to cleaner, more efficient engines for cars. The discovery was made during a series of experiments on the International Space Station by a team led by Forman Williams, a professor of mechanical and aerospace engineering at the Univ. of California, San Diego.
Virologists and biologists in California have identified a highly abundant, never-before-described virus that could play a major role in obesity, diabetes. The virus, named crAssphage, has about 10 times as many base pairs of DNA as HIV and infects one of the most common types of gut bacteria. This phylum of bacteria is thought to be connected with obesity, diabetes and other gut-related diseases.
More than a decade ago, news of a Namibian desert beetle’s efficient water collection system inspired engineers to try and reproduce these surfaces in the laboratory. Small-scale advances in fluid physics, materials engineering and nanoscience since that time have brought them close to succeeding. And their work could have impact on a wide range of industries at the macroscale.
In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by NASA's Fermi Gamma-ray Space Telescope. It was as if someone flipped a switch on the pulsar.
Bamboo construction has traditionally been rather straightforward: Entire stalks are used to create latticed edifices, or woven in strips to form wall-sized screens. The effect can be stunning, and also practical in parts of the world where bamboo thrives. But there are limitations to building with bamboo.
Graphene, a material that consists of a lattice of carbon atoms, one atom thick, is widely touted as being the most electrically conductive material ever studied. However, not all graphene is the same. With so few atoms comprising the entirety of the material, the arrangement of each one has an impact on its overall function.
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. A new study from Massachusetts Institute of Technology materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons.
Researchers at the Univ. of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances less than ~600 nm for red light). A standard optical microscope acts as a “nanocamera” whereas the pBNAs are the analogous film.
Twisting a screwdriver, removing a bottle cap and peeling a banana are just a few simple tasks that are tricky to pull off single handedly. Now a new wrist-mounted robot can provide a helping hand—or rather, fingers. Researchers at Massachusetts Institute of Technology have developed a robot that enhances the grasping motion of the human hand.
The repetitive facilitation exercise is one of the most common rehabilitation tactics for stroke patients attempting to regain wrist movement. Stroke hemiparesis individuals are not able to move that part of their body because they cannot create a strong enough neural signal that travels from the brain to the wrist.
Biological physicists at Rice Univ. have succeeded in analyzing transmembrane protein folding in the same way they study the proteins’ free-floating, globular cousins. They have applied energy landscape theory to proteins that are hard to view because they are inside cell membranes. The method should increase the technique’s value to researchers who study proteins implicated in diseases and possibly in the creation of drugs to treat them.
A team including scientists from Spain and from IBM Research in Switzerland have published work which describes an extremely simple method to obtain high quality nanographenes from easily available organic compounds. This method is based on the reactivity of a group of molecules named arynes, which can act as "molecular glue" to paste graphene fragments together.
Researchers in Kentucky have developed a technology that uses male mosquitoes to effectively sterilize females through a naturally occurring bacterium. Called MosquitoMate, the new technology has been issued an experimental use permit for open field releases targeting the invasive Asian tiger mosquito, which is a vector for newly introduced pathogens like the Chikungunya virus.
In the movie “Terminator 2,” the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.
