5:44 PM | A Brief Guide to the Twenty Common Amino Acids
The proteins that make up living organisms are huge molecules, but they’re composed of tinier building blocks, known as amino acids. There are over 500 amino acids found in nature, yet, of these, the human genetic code only directly codes for 20. Every protein in your body is made up of some linked combination of these amino […]

4:21 PM | Researchers capture motion of single molecule in real time
Chemists have scored a scientific first: capturing moving images of a single molecule as it vibrates, or 'breathes', and shifts from one quantum state to another.
+
4:15 PM | For electronics beyond silicon, a new contender emerges
Using a quantum material called a correlated oxide, researchers have achieved a reversible change in electrical resistance of eight orders of magnitude, a result the researchers are calling 'colossal'. In short, they have engineered this material to perform comparably with the best silicon switches.

3:18 PM | The extended stability range of phosphorus allotropes made of nanotubes
What holds white, black, and red phosphorus together - and prevents it from falling apart, for example into much-sought-after atomically thin networks and nanowires? This is what scientists now found out using numerical modeling.

3:04 PM | Advanced molecular 'sieves' could be used for carbon capture
Newly-developed synthetic membranes provide a greener and more energy-efficient method of separating gases, and can remove carbon dioxide and other greenhouse gases from the atmosphere, potentially reducing the cost of capturing carbon dioxide significantly.

2:45 PM | New model to study the nanoscale motion patterns of bacteria in real time
Researchers have developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony. They chemically attached colonies of E. coli bacteria to a microcantilever, coupling its motion to that of the bacteria.

2:41 PM | Au Revoir, Auf Wiedersehen, Adios..to The Real World Blog
Eric F. Brown, author of the blog The Rheol World" signed off for the last time yesterday. His blog will be missed as during it's heyday around 2010, it was pretty active, being both humorous and informative. Sadly the posting frequency has slacked off greatly as of late and yesterday the end was formally announced. I'm hoping Eric can restart the blog sometime in the future, so I will await that day patiently. My RSS feeder will be sure to alert me.Do stop by his blog once last time and be […]

2:38 PM | Rolith and Protemics Announce Cooperation on Nanostructured Anti-Counterfeiting Technology
Rolith's proprietary security labels based on metallic nanostructures are invisible to the human eye and standard inspection equipment but can be revealed using Terahertz microprobe sensors from Protemics.

2:35 PM | The fate of the Efimov trimer under confinement
As well as providing new fundamental insights into this prototypical few-body problem, new research results have important implications for on-going atomic experiments aimed at detecting universality in the three-body system, and it opens new avenues towards the realisation of long-lived many-body states of trimers.

12:53 PM | Meet our guest bloggers – Jen Dougan
My name is Jen Dougan and I am a Field Applications Scientist with an SME, developing diagnostic tools for clinical analysis. My job involves working with our R&D teams and customers in the field to drive and support product and applications development. I recently moved into this position after a PhD and two post-docs (and [...]

11:43 AM | Do a postdoc with eNanoMapper
CC-BY-SA from Zherebetskyy @ WP.Details will still have to follow as they are being worked out, but with Cristian Munteanu having accepted an associate professorship, I need a new postdoc to fill his place, and I am reopening the position I had almost a year ago. Do you like to works in a systems biology group (BiGCaT), are pro Open Science, like to work on tools for safe-by-design nanomaterials, and have skills in one or more of bioinformatics, chemoinformatics, statistics, coding, […]

10:58 AM | New study helps uncover mechanism behind solid-solid phase transitions
Two solids made of the same elements but with different geometric arrangements of the atoms, or crystal phases, can produce materials with different properties. Coal and diamond offer a spectacular example of this effect. Researchers have now found that some crystals have an easier time of making the solid-solid transition, if they take it in two steps.

6:02 AM | Nanoparticles in Prosthetics & Bionics
During my time in the Marine Corps I met several people that lost limbs in the war. I made the decision to leave the service to get my degree. Inspired by my fellow soldiers, my ultimate goal is to start a company making prosthetics and bionic limbs, hopefully making their lives a little bit easier. […]

12:11 AM | This week's C&EN
Lots going on in this week's issue:Surely it means something that Indian pharmaceutical company Piramal is ending its drug discovery efforts in India? How odd. (article by Jean-François Tremblay)Enjoyed reading about Samantha Arnett, Ph.D. bioinorganic chemist and the State Department's Biosecurity Engagement Program's manager. (article by Deirdre Lockwood) (registration required)I found this letter by Martin Feldman of Howard University very interesting and a rather pointed critique of […]

7:33 PM | Happy Birthday to the man with five brains
Today is Murray Gell-Mann's birthday. John Brockman calls him "the man with five brains, each one of which is smarter than yours". We are thankful he is still with us and holding forth on a variety of important problems. Gell-Mann of course is famous as the man who, inspired by a line from a book which he predictably would be the right person to have read, invented quarks. Nobody has observed an isolated quark yet, but there have been plenty of Nobel Prize-winning experiments confirming their […]

4:40 PM | What's wrong with this picture?
Courtesy of Bubba at In The Pipeline, a truly amusing set of bad chemistry structures behind this fake chemistry teacher.(Surely correcting bad chemistry in Hollywood could be a paying job for someone, right?)Also, a very perceptive comment from him:"If you don't watch TV between 6 and 7pm, then you are entirely missing the public face of pharma."Oh, dear, I'm afraid that's true.

3:30 PM | Morning tidbit: 538 on why STEM is TE
Ben Casselman, an economics writer for 538, Nate Silver's data website, has written "an economic guide to picking a college major". Here's a rather lovely paragraph:All STEM fields aren’t the same Politicians love to tout the importance of science, technology, engineering and math majors. But when it comes to earnings, the “S” majors don’t really belong with the “TEM” ones. Engineering majors are nearly all high-paying. So are most computer and math […]

3:09 PM | Plastics Scorecard v1.0 - I can't wait for v2.0
Being that I've spent my whole career working with plastics, I've had more than my fill of anti-plastic nonsense. But most of it is "harmless" statements about how bad plastic is. Statements such as "every piece of plastic ever made is still in existence" or any of a number of inane statements about "floating island of plastic in the ocean" or statements made by people thinking they are living a plastic-free life. When such statements are made by unprofessional individuals, I seldom get worked […]
