Scientific innovation lifecycle management solutions provider Accelrys has added to its enterprise capabilities with the acquisition of Ireland-based QUMAS for $50 million in cash. QUMAS is a global provider of cloud-based and on-premises enterprise compliance software supporting regulatory and quality operations in life sciences and other highly regulated industries.
Scientists from the Univ. of Toronto have discovered a novel chemical lurking in the atmosphere that appears to be a long-lived greenhouse gas (LLGHG). The chemical—perfluorotributylamine (PFTBA)—is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to affect climate.
Researchers have determined the structure of the rubella virus capsid protein, which is central to the virus's ability to assemble into an infectious particle and to infect humans. Although a successful vaccine is available to protect against rubella virus infection, the discovery could aid efforts to develop vaccines and antiviral drugs to treat related infections.
To learn new motor skills, the brain must be plastic: able to rapidly change the strengths of connections between neurons, forming new patterns that accomplish a particular task. However, if the brain were too plastic, previously learned skills would be lost too easily. A new computational model explains how the brain maintains the balance between plasticity and stability, and how it can learn similar tasks without interference.
Q?rius (pronounced “Curious”) is a new hub of scientific activity and education based at the Smithsonian’s National Museum of Natural History in Washington D.C. The product of a partnership between Olympus and the Smithsonian, the 10,000-square-foot experiential learning center will be equipped with dozens of microscopes and imaging systems that will enable museum visitors more than 6,000 bones, minerals, and fossils.
Phenomenex Inc. has introduced a new 30-nm internal diameter Kinetex core-shell 5-micron column in Axia hardware for preparative HPLC and SFC in pharmaceutical laboratory-scale purification. Also offered in a 21.2-mm internal diameter, the 30-mm column enables increased sample loading and throughput.
Thorlabs has introduced two fiber-coupled, broadband tungsten light sources (SLS201/SLS202), extending its broadband light sources product offering to spectroscopy for chemical, medical and biological analysis. The sources come in two versions, both featuring a constant intensity blackbody radiation spectrum that ranges from either 300 to 2,600 nm (tungsten-halogen) or 450 to 5,500 nm (tungsten).
By using optical techniques, researchers in Switzerland are now able to measure the concentration of the oxidizing substances produced by a damaged cell. This new biosensing technique for toxic agents also offers a new way to know more about the mechanisms of oxidative stress.
With the help of the x-ray light source PETRA III, researchers in Germany have, for the first time, watched organic solar cells degrade in real time. This work could open new approaches to increasing the stability of this highly promising type of solar cell, which is known for its flexibility and low cost but has a short lifespan.
Univ. of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is important.
The Titan Arm, a robotic device invented by Univ. of Pennsylvania engineering students, looks and sounds like part of a superhero's costume. But its creators say it's designed for ordinary people—those who need either physical rehabilitation or a little extra muscle for their job. The arm can help its wearer carry an additional 40 pounds.
Even as Silicon Valley speaks out against the U.S. government's surveillance methods, technology companies are turning a handsome profit by mining personal data. Tarnished by revelations that the National Security Agency trolls deep into the everyday lives of Web surfers, companies like Apple, Facebook, Google, and Microsoft are aggressively battling any perception that they voluntarily give the government access to users' information.
Forensic experts have long used the shape of a person’s skull to make positive identifications of human remains. But those findings may now be called into question, since a new study from North Carolina State Univ. shows that there is not enough variation in skull shapes to make a positive identification.
With one stomp of his foot, Zhong Lin Wang illuminates a thousand light-emitting diode (LED) bulbs, with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip to a doorknob when you walk across carpet on a cold, dry day. Wang and his research team have learned to harvest this power and put it to work.
Heating a sheet of plastic may not bring it to life, but it sure looks like it does in new experiments at Rice Univ. The materials created by Rice polymer scientist Rafael Verduzco and his colleagues start as flat slabs, but they morph into shapes that can be controlled by patterns written into their layers.
