7:32 AM | Competition in the quantum world
Innsbruck physicists led by Rainer Blatt and Peter Zoller experimentally gained a deep insight into the nature of quantum mechanical phase transitions. They are the first scientists that simulated the competition between two rival dynamical processes at a novel type of transition between two quantum mechanical orders.

6:30 AM | Ways to Fail an Interview
Not the cheeriest of titles for a Monday morning, but an important topic non the less.  I came across this article over the weekend via Twitter and as someone who has carried out numerous interviews in my career, and provided advice to people about preparing for interviews I thought it summed up some of the key reasons why people don't succeed when they go along for that all important job interview. The article goes into more detail but it highlights the top 3 reasons why people […]

3:25 AM | Being discovered
Recently we have seen on the American Chemical Society website a sign  “Publish Be Found or Perish”. This rings a bell with me because there is a similar discussion going on with book authors. Yes, you have to write something that is worth reading, either with books or with scientific papers, but the whole exercise is a waste of effort unless someone reads the work, and by definition, quality has nothing to do with the first reading because if you do not know what is in the […]

5:40 PM | #chemclub Roundup 9
A quick round-up of posts to #chemclub from the past fortnight. Last week, #chemclub was featured at Grand CENtral - so hello to any new readers! On the blogs, a few papers have been discussed in depth. At It's The Rheo Thing, John talks about the glass transition of Teflon, which turns out to be pretty involved. Both C&EN and In the Pipeline featured a recent Science paper about iron-catalysed

9:11 AM | Bioengineers go retro to build a calculator from living cells
Scientists in the US have developed a calculator from living cells, using old-fashioned analog programming. Their hope is that the technology could be used in the future to program cells to kill cancer. Researchers have previously built electronic circuits using living cells. They achieved this by forcing living cells to behave in binary (digital) systems. But this is not energy efficient. And many cells are required to implement simple functions that transistors, the basic units of electronic […]

5:23 PM | EC-funded NanoSustain publishes four nanotechnology case studies
The EC-funded NanoSustain project has been developing new sustainable solutions through an investigation of the life-cycle of nanotechnology-based products, in particular the physical and chemical characteristics of materials, hazard and exposure aspects, and end-of-life disposal or recycling to determine the fate and impact of nanomaterials.

5:12 PM | Hey, that's not the right data!
Some of you may have seen this James Hicks article in The Scientist, where he shows a graph that seems to correlate high notices of retractions with low NIH grant success rates. Interesting idea, right?Unfortunately, Nature reporter Richard Van Noorden (the collector of some of the data used in the graph) notes that Professor Hicks did not use the most relevant data for his retractions (i.e. US retractions, funded by the NIH) for his graph. When you do, the correlation is not nearly […]

2:57 PM | Nanoparticle delivers large protein complex to cancer cell nucleus
Drug developers have been using nanoparticles to encapsulate a wide range of molecules for delivery to tumors. Now, they can add a large protein complex to that list thanks to research from the laboratory of Yi Tang of the University of California at Los Angeles.

2:54 PM | Protein 'passport' helps nanoparticles get past immune system
The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt, or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted devices, like pacemakers or artificial joints, are just as foreign and subject to the same response. Now, however, a team of researchers has identified a 'passport' for such therapeutic devices, enabling them to get past the body's security system.

2:51 PM | Nanoparticle harnesses powerful radiation therapy for cancer
Researchers at the University of Missouri have demonstrated the ability to create a multi-layered harness nanoparticle that can safely encapsulate powerful alpha-emitting radioisotopes and target tumors. The resulting nanoparticles not only offer the possibility of delivering tumor-killing alpha emitters to tumors, but also sparing healthy tissue from radiation damage.

2:48 PM | Microneedle-delivered nanoparticles boost anti-tumor vaccines
In the quest to develop anti-cancer vaccines that would stimulate the body to destroy tumors and keep them from recurring, researchers continually run into the same problem - the immune-stimulating proteins, known as antigens, are not interacting effectively with the key immune system cells that trigger long-lasting immune responses. Now, using a novel administration system and polymer nanoparticles, a team of investigators led by Adrien Kissenpfennig of Queen's University Belfast has shown […]

2:44 PM | New nanopore sensor simplifies analysis of methylated DNA
DNA methylation, the addition of a methyl group to specific locations on a DNA strand, plays a critical role in determining which genes are active in a cell at any given time. It plays an important role in embryonic development, cell growth and reproduction, and many diseases, including cancer. Now, researchers collaborating at the Mayo Clinic and the University of Illinois in Urbana-Champaign have developed a novel single molecule test for detecting DNA methylation that should greatly simplify […]

2:19 PM | Man, I want to go to China someday to give a talk
From international political economy professor Daniel Drezner, a comment on being paid honoraria for speaking in China:1) From a personal perspective, as the occasional visitor to China, I can confirm the wads of cash thing -- but it's a bit more complicated than Barboza suggests. First of all, for U.S. academics at least, the payment isn't in renminbi, but in U.S. dollars. Renminbi is sometimes dispensed for things like per diem reimbursements, but not for honoraria. After all, officially, the […]

1:41 PM | Dow Chemical Hit With Triple Damages for Price Fixing Case
It's official. Dow Chemical now has to pay triple damages after being found guilty of price fixing urethane components. That means that the $400 million dollar fine that the jury established is now a whopping $1.2 BILLION dollar fine. $400 million is so small that Dow could have almost hidden that in the annual report, but with $1.2 billion, that is going to show up loud and clear.Do you hear that sound coming from the general direction of Midland, Michigan? That's the sound of lawyers […]

1:40 PM | Alchemy vs Chemistry: Same as it ever was
… The more things change, the more they stay the same. I’m currently reading The Secrets of Alchemy by Lawrence Principe. It’s a really enjoyable book, and I’ve learned so many things from it. I hope to share some of my favorites. But, I’ve just read a bit of Principe’s research in the book that seems poignant for my profession (chemistry) in these times. (In any book, there is always some bit: character, place, situation, or story that seems very relevant to […]
