4:50 PM | Eurodim 2014: a brief report
Eurodim 2014, the 12th Europhysical Conference on Defects in Insulating Materials, was held at the University of Kent from 13-19 July 2014. I have attended the Eurodim/ICDIM series of conferences fairly continuously for the past 30 years; previously I organised Eurodim 1998 at Keele, and helped organise the programme for ICDIM 2008 in Aracaju, Brazil.

3:20 PM | Thought for the Weekend
While writing up case reports regarding synthetic cannabinoid-associated deaths and reading other reports, this thought occurred...Synthetic cannabinoid receptor agonists (especially newer generation compounds from 2013+) are a diverse chemical grab bag o' "fun". Fun is defined here as adverse effects including tachycardia, seizure, nephrotoxicity, and death.If you choose to partake in the substances, then keep that in mind. And no, I do not recommend or condone using synthetic cannabinoid […]

4:02 PM | Mystery Men
Three faceless men crouch in front of a device. The first grasps a small pot, preparing to add it to a pile of finished pottery. An enormous factory looms over him. The others look on, envious of the factory that makes pots so easily. Except they are not even facing the factory, and … I clearly have no idea what I’m talking about. All I know is that this picture is somehow connected to the Atoms for Peace program. The rest is a mystery. Part of the Atoms for Peace mission was to […]

4:01 PM | Why STEM is TE: post-secondary education requirements edition
From the Minneapolis Star-Tribune, a fascinating microcosm of the STEM problem: Casale said during the recession, the education level expected by Minnesota employers rose and as the state bounced back, degree requirements fell. In June, the state had the 10th-lowest unemployment rate in the nation. Still, there are remaining factors that determine a higher degree’s level of success — especially its area of focus. In the fourth quarter of last year, 80 percent of responding […]

3:42 PM | Sciencebase Fifteenth Anniversary
It was 20th July 1999 when I first registered the domain name sciencebase.com and transferred my old Elemental Discoveries websites from various ISP and freenet type hosts to this super hub of science. Don’t the years just fly by? At that time, I was quite serious about building up a science portal (as they were […]Sciencebase Fifteenth Anniversary is a post from the science blog of David Bradley, author of Deceived Wisdom Subscribe to our Email Newsletter

2:39 PM | Scientists test a nanoparticle 'alarm clock' to awaken immune systems put to sleep by cancer
Researchers are exploring ways to wake up the immune system so it recognizes and attacks invading cancer cells. Tumors protect themselves by tricking the immune system into accepting everything as normal, even while cancer cells are dividing and spreading.

1:59 PM | So, what's new?
A few days ago, one of my coworkers at the new job asked me to tell them what the newest, coolest trends in synthetic organic chemistry were. And, I readily confessed, even though I write this blog, I'm still in the dark about exactly what folks find exciting, even week to week! New ligands for palladium? Been there.Protecting group-free synthesis? Done that.SF5? CF3? Polyfluorination? Old news, now.Even cobalt, which seems to be the new darling of the catalysis community, feels like it's […]

1:53 PM | Here we go again: biologicals are chemicals, too
I should probably quit beating this drum, but I cannot resist this one. From the Washington Post's Health Reform Watch, Jason Millman writes about the new FDA biosimilars news:The Food and Drug and Administration for the first time has accepted an application for a copycat version of what's known as a biologic, which is a complex drug made from proteins of living organisms. These biologics are cutting-edge therapies that can be more effective than regular drugs made from chemicals — and, […]

1:52 PM | New study calls into question the existence of silicene
A recent study at the U.S. Department of Energy's Argonne National Laboratory has called into question the existence of silicene, thought to be one of the world?s newest and hottest two-dimensional nanomaterials.

1:39 PM | Connecting a USB memory stick/drive to a Nexus 7 tablet
Following my post of the end of last week about using a tablet instead of a laptop at a conference, another unforeseen issue I encountered was how to read a USB memory stick using the tablet. The conference provided all the information on a memory stick, but I couldn’t read it with the Nexus! (It […]

11:30 AM | To Chemistry World... and beyond!
I've started a new gig guest blogging for Chemistry World. Over there I'll be doing that thing where I praise (or poke fun at) academic journal cover art. So head on over there now and check out my first post about a crazy colour explosion in Chem Soc Rev.

11:02 AM | The Many Faces of Ethanol: chemical, drink, poison, medicine, metabolite ….
For many, summer is synonymous with enjoying an alcoholic drink outdoors, while bathing in the sun! In this case, the term alcohol actually refers to ethanol, the product of fermentation of different fruits and vegetables. However, for chemists, there is so much more to ethanol than a simple beverage… Ethanol as a chemical From a [...]

1:50 AM | Publication of the week, number 35, 25th July 2014
Apart from synthesising your target molecule there is nothing more pleasing than the desymmetrisation of a symmetrical molecule producing a useful chiral synthon.  This week’s offering does just that. Described by the group of Jieping Zhu at the ETH Lausanne they synthesised the chiral fragment shown below. This compound was first prepared by Kuehne and used […]

1:16 AM | Genius and Einstein: From 'Great Man' to 'Every Man'?
Einstein is the poster child for genius because he was a geniusThe American organic chemist Robert Burns Woodward was a genius; the craft at which he excelled better than anyone else was making molecules, some of which were so complex that nobody before him thought they could be made. While little known to the general public, the perception of Woodward as an authentic genius was widely shared by his students and colleagues, several among whom counted themselves among the leading chemists of […]

8:06 PM | Anyone ever had grad student/postdoc pay stop because of the university changing its policies?
I'm hearing about grad students at a research university having their pay periods change, and therefore basically missing a paycheck. There is blame on the Affordable Care Act, which is a little odd.What happens in these sort of situations? Has anyone ever heard of such a thing? What is the most effective way for a group of graduate students or postdocs to mount a response?
