9:57 AM | Beyond six nines: Ultra-enriched silicon paves the road to quantum computing
Using a relatively straightforward technique, a team of researchers has created what may be the most highly enriched silicon currently being produced. The material is more than 99.9999% pure silicon-28, with less than 1 part per million of the problematic isotope silicon-29.

8:14 AM | Could hemp nanosheets topple graphene for making the ideal supercapacitor?
As hemp makes a comeback in the US after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors.

4:57 PM | StripeyNanoparticleMania 2015!
Also in this week's C&EN, this letter to the editor:Having read “Big Tussle over Tiny Particles” with great interest, I suggest that ACS sponsor a meeting between the parties involved and provide objective observers (C&EN, May 26, page 43). Francesco Stellacci would bring his nanoparticles, and Philip Moriarty would operate the scanning tunneling microscope at various gain settings. Everyone present would see for themselves whether the nanoparticles were actually striped or […]

3:41 PM | This week's C&EN
Lots of interesting things in this week's C&EN:Big feature on the 100th anniversary of crystallography this week, including a fun editorial by Greg Petsko: "Clearly we are still a long way from the day when all structures of all molecules will simply be calculated from first principles. But if you seriously think that day will never come, I suggest you think again." This would make a great long bet, as to when that day would come. As a non-biologist, I learned a lot from this Matt […]

In a Philadelphia basement a family buried their pet dog and hamster with a doll’s head. More than 200 years later, archaeologists excavated the basement and found the curious burial ground. Why did the family bury their pets inside their home? What significance did the doll head have? No one knows, but a group of archaeologists working on the Digging I-95 project are studying a plethora of artifacts to learn about the lives of Philadelphians from the 1800s. Working for the URS […]

10:18 AM | Should we fear the Ebola virus or not?
“Breaking news: Ebola virus has been declared as an international public health emergency by the World Health organization”That sentence was the first thing I saw when I logged into Facebook as I’ve started planning and writing this article.What is the Ebola virus (EBOV)? BBC Ebola VirusThe Ebola virus is a very terrible disease and lethal if caught and it has a high fatality rate of 60% (WHO 01/04/2014) [1] Ebola is not an airborne virus but it can be spread via bodily fluids […]

8:32 AM | Managing expectations
Being realistic in your expectations   We are told to aim for the stars; that we can do anything we want with our career. I know because I say it to people I speak to; I do however add a caveat: you will need to be realistic.   We all have expectations, of the people we know, our friends and colleagues, our family; the TV we watch; the food we eat; even the service we expect as a customer. For most of the time we don’t give these expectations a second thought; that is until we […]

8:27 AM | New journal of the month resource series
As I mentioned in my earlier post on our annotated journal articles, research has shown that students can find it difficult to interpret and understand the information in journal articles. This can cause problems when they arrive at university and need to start using journals independently, so we've decided to launch a number of resources aimed at making our publishing activities more accessible to those studying chemistry at a variety of levels.  We want to make sure that students […]

7:00 AM | NFL Players Sue over Painkillers—Because They’re Addicted
By: Andrew Huhn, 4th year PhD candidate in the Neuroscience Graduate Program America loves football. Brutal, high-flying, smash-mouth football. The players seem like gladiators from another era. Chiseled out of stone, they feel no pain as they run, jump, and catch with a grace that appears super-human. The reality is, however, that they do feel pain—and often…

10:27 PM | Hypervalent carbon
One of the more unusual publications recently involved a theoretical computation of a hypothetical carbonium ion (or at least a very short-lived molecule-ion) C-(CH3)5 . (Angew. Chem. Int. Ed 53: 7875 – 7878.) Computations concluded that the structure was that of a trigonal bipyramid, which effectively had three methyl groups around the central carbon atom, which was in sp2 configuration, and two other methyl groups bonded to the p orbital of the central carbon atom. All methyl groups […]

3:44 PM | The new Premier League season: finance and hype
With the start of the new Premier League season less than a week away, I find myself not exactly looking forward to it. All the top teams have been busy spending ridiculous sums of money to strengthen their squads – OK, it’s what you have to do, but it has diminished the sport so much […]

3:43 PM | The new Foursquare Android app: initial reaction
The new Foursquare Android app became available from the Google Play Store last Wednesday, 6th August. I’ve been using it pretty continuously since then, and can offer an initial appraisal. I’ve already discussed at length my disappointment that Mayorships, badges and (finally) points were lost, so I judge the app as it is and not […]

3:25 PM | Like cling wrap, nanosheet material can coat tricky burn wounds and block out infection
Wrapping wound dressings around fingers and toes can be tricky, but for burn victims, guarding them against infection is critical. Today, scientists are reporting the development of novel, ultrathin coatings called nanosheets that can cling to the body's most difficult-to-protect contours and keep bacteria at bay.

3:21 PM | The grass really is greener on TV and computer screens, thanks to quantum dots
High-tech specks called quantum dots could bring brighter, more vibrant color to mass market TVs, tablets, phones and other displays. Today, a scientist will describe a new technology called 3M quantum dot enhancement film (QDEF) that efficiently makes liquid crystal display (LCD) screens more richly colored.
