Normally, Wired Science blogger Deborah Blum would be teaching an investigative reporting class at the University of Wisconsin in the fall. Now, it looks as though her class might be shut down -- for very political reasons.

A new study found that the shape of nanoparticles can enhance drug targeting. According to this study, rod-shaped nanoparticles - or nanorods - as opposed to spherical nanoparticles, appear to adhere more effectively to the surface of endothelial cells that line the inside of blood vessels.

There is a recent editorial by Geoffrey North in the scientific journal Current Biology about the dangers of social media on science. And although it’s titled “Social Media Likes and Dislikes” there is much more dislike than like. In it, he quickly mentions the 2010 scandal about arsenic-based life, published to Science but ultimately found […]

Courtesy of Dean Baker and Kevin Hassett (two economists that are not exactly on the same side of the ideological spectrum) in the New York Times last month:While older workers are less likely to be laid off than younger workers, they are about half as likely to be rehired. One result is that older workers have seen the largest proportionate increase in unemployment in this downturn. The number of unemployed people between ages 50 and 65 has more than doubled. The prospects for

In this week's C&EN, a fascinating article on the returnees to Chinese chemical academia by Shawna Williams:When Kuiling Ding joined the faculty of China’s Zhengzhou University as an assistant professor in 1990, he signed a five-year contract and in exchange received 5,000 yuan—about $1,350 according to the exchange rate of the time—in housing assistance. “At that time 5,000 yuan was still a big number,” he says—at least compared with his salary, which was less than 1,000 yuan

Seems like chemical employment-related letters are showing up more and more in the pages of C&EN -- here's the latest batch in this week's C&EN:Wm. Charles Jamison’s letter was spot-on (C&EN, April 15, page 2). The top priority for the American Chemical Society should be to improve the job market and benefits for U.S. chemists and biochemists at all levels. We are going through a painful period in which too many chemists are unemployed, unemployable because of their age, or just

The research team demonstrated a novel method to epitaxially synthesize structurally and compositionally homogeneous and spatially uniform ternary InAsyP1-y nanowire on Si at wafer-scale using metal-organic chemical vapor deposition (MOCVD). The high quality of the nanowires is reflected in the remarkably narrow PL and X-ray peak width and extremely low ideality factor in the InAsyP1-y nanowire/Si diode.

Today, the International Energy Agency put out a report saying that CO2 emissions in 2012 grew by 1.4%, or 31.6 gigatonnes. This increase means that the chances of constraining emissions to cap global warming at 2 degrees C are narrowing. When I first started covering the cleantech/renewables space for C&EN back in 2008, there was [...]Related Posts:But In the Meantime, More CO2Codexis Puts Enzyme to Work for Clean(er) CoalPalm Oil Not Clean Enough for RFS, says EPASome Carbon Credit

For many types of surgery or for a bad cut on the skin, stitches are just fine. They bring the tissues together and speed up the healing process. But for some types of surgeries, you really need something better—something that will form a leak-proof, tight seal. This is especially important for intestinal surgeries. The intestines are where your food goes after the stomach. The small intestine is about 20 feet long, and most of your digestion happens here. It also absorbs lots of

Macro Letters has a new article entitled: "Sustainable Polymers: Opportunities for the Next Decade". As this was in Letters, the review is brief. A major focus is on water degradable polyacetals, polycarbonates and polyoxalates that are derived from lignins, and also on formaldehyde based polymers, which the author calls "the new polyethylene". I find all of this chemistry quite interesting as it is rather remote from what I learned in school (and in my career thus far). These polymers will […]

Researchers have found novel probes that could help to better understand a critical developmental signal-transduction pathway. These probes are small-molecule inhibitors of the Sonic Hedgehog signaling pathway which, besides being essential for body segmentation in insect and vertebrate embryos, has been implicated in some cancers and developmental diseases. The work appears in the Journal of […]

Two exciting new features will soon be available for the 9103 Picoammeter: Synchronization and Device Identification. These features transform the 9103 from a single current measurement device to a multi-channel picoammeter. Picoammeter Synchronization Synchronization is provided by RBD’s free … Continue reading →The post Synchronizing and Identifying Multiple 9103 Picoammeters appeared first on RBD TechSpot.

Nanotechnology-enabled, paper-based sensors promise to be simple, portable, disposable, low power-consuming, and inexpensive sensor devices that will find ubiquitous use in medicine, detecting explosives, toxic substances, and environmental studies. Since monitoring needs for environmental, security, and medical purposes are growing fast, the demand for sensors that are low cost, low power-consuming, high sensitivity, and selective detection is increasing as well. Paper has been recognized as a […]

Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of molecular entanglement is an important field of study as the presence of knots affects its physical properties, for instance the resistence to traction.

Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in. Atoms on iron-oxide surfaces behave in a similar way: Only with the right molecular partner do they dance across the surface. Scientists have now filmed the atoms, proving that carbon monoxide is the partner responsible for the quick motion.

Picosun Oy, leading Atomic Layer Deposition (ALD) equipment manufacturer, reports excellent process results for copper diffusion barrier deposition. ALD materials for copper diffusion barriers were investigated in the project ESiP (Efficient Silicon Multi-Chip System-in-Package Integration - Reliability, Failure Analysis and Test), running from May 2010 to June 2013.
