6:06 PM | New Segment: Scientist of the Week!
After my previous blog post Science: It's a Girl Thing I have decided to start a new segment where I will be choosing a scientist from different branches of science and could be male and female and provide a profile / case study dedicated to that scientist. This segment will be: Scientist of the Week and will be posted every Friday commencing from Friday 6th March 2015 !Can you guess which scientist I will be starting with?

2:59 PM | Distillations Podcast: Innovation & Obsolescence—The Life, Death, and Occasional Rebirth of Technologies
Some technologies flash in the pan so quickly they hardly leave a trace (Google Glass anyone?); while others seem to stick around long past their use by date. And still other creations appear to be gone for good, only to make a comeback within a niche—and likely nostalgic—community. We set out to explore the rhymes and reasons behind these ebbs and flows of technological innovation and obsolescence. First we go to a place where digital nostalgia is alive and well: a vintage video […]

2:58 PM | Gotta love George Whitesides
Courtesy of See Arr Oh (who has a very cogent (and funny) post on this), here's George Whitesides criticizing (again) the chemical industry: This choice of direction has had several consequences: 1) it has ended (or constrained in scope and character) the unique and mutually beneficial intellectual partnership between industrial and academic chemistry that characterized the 1960s to 1980s (Figure 3). 2) It has increasingly limited the number of jobs for chemists in industry, and made a […]

1:46 PM | Boar semen biomarkers predict litter size
Pig business is big business. In 2012 alone, China, the world’s largest producer of pork, produced 50 million tons of the meat. Getting pigs to reliably produce large litters is of great economic importance in places like China, the United States and the European Union. In a new study just published in Molecular & Cellular […]

1:43 PM | European Food Safety Authority publishes risk assessment of nanotechnologies in food and feed
The overall goals of EFSA's Nano Network are to provide a forum for dialogue among participants; build mutual understanding of risk assessment principles; enhance knowledge on and confidence in the scientific assessments carried out in EU; and to provide increased transparency in the current process among Member States and EFSA on nanotechnology. All this with the aim to raise the level of harmonisation of the risk assessments developed in the EU on nanotechnology.

1:10 PM | Friday Fun: WWWTP? Linkin Park Edition
Through the wonders of the Internet, I've found this still image from the 2003 Linkin Park video for "Numb":In the video, a young, disaffected student dreams of traveling to far-flung cities to practice her true talent - sculptural drawing. However, it seems an evil chemistry professor stands in her way.But look behind the (hilariously stereotyped) man with the chalkboard pointer. NaK...as an alloy, perhaps? And how come there's a subscript number before the nitrous acid?If that were […]

11:10 AM | Silent Spring master notes
I posted my song, The Silent Spring from critique on one of the songwriter forums and got a few listens and some nice positive comments, in particular with regard to the mastering I did…an area in which I’m really just a novice. But, here are a few notes about what I did, just for my […]Silent Spring master notes is a post from the science blog of science journalist, photographer and musician David Bradley Subscribe to our Email Newsletter

9:01 AM | The Many Uses of Surgical Spirit
Surgical spirit is simply a denatured alcohol solution containing ethyl alcohol (ethanol) and methyl alcohol (methanol), also known as rubbing alcohol. In addition to these ingredients, it also includes certain additives to render it bitter, as well as dyes to warn against abuse. Applications take advantage of its antimicrobial properties, as well its ability to [...]

8:33 AM | Ordered nanostructures from benzene could pave the way for novel nanotechnology applications
A way to link benzene rings together in a highly ordered three-dimensional helical structure using a straightforward polymerization procedure has been discovered, potentially opening up new areas of nanocarbon and materials science.

6:06 AM | Publication of the week, number 66, 27th February 2015
It’s not often these days that starting to read a paper makes me sit up and really want to read further. Some that have achieved this “distinction” I’ve commented on here. This week I came across another one! It’s presented by Trapp and Storch from the University of Heidelberg in Germany. It presents us with a new … Continue reading Publication of the week, number 66, 27th February 2015 →

9:40 PM | The Chemistry of Poisons – Cyanide
The second in the series on poisons looks at cyanide, another notorious agent of murder. It’s played a role in genocide, in suicide pills, and is also found in small amounts in the seeds of numerous fruits. So, why is cyanide so poisonous, and why are deaths from cyanide poisoning less of a rarity than those from arsenic […]

7:49 PM | Now that's an unfortunate title
I suspect this is actually one of those academic drug discovery former-pharma group leader positions, but tagging it with "adjunct professor series" is kinda painful.

4:45 PM | A new X-ray microscope for nanoscale imaging
Delivering the capability to image nanostructures and chemical reactions down to nanometer resolution requires a new class of x-ray microscope that can perform precision microscopy experiments using ultra-bright x-rays from the National Synchrotron Light Source II at Brookhaven National Laboratory.

4:37 PM | New research predicts when, how materials will act
A material might melt or snap in half. And for engineers, knowing when and why that might happen is crucial information. Now, a researcher has laid out an overarching theory that explains why certain materials act the way they do.

4:32 PM | Prevent problems with proper planning
Guest post by Heather Cassell One of the great joys of being in the lab is being in charge of your own experiments, from designing what you want to study to the interpretation of the results. Having responsibility for your work from conception to completion is challenging and ultimately rewarding. The first step in designing your [...]

3:38 PM | What is Global Pharma Tek's business model?
Saw this ad through an Indeed search. What is this about? Global Pharma Tek has a website listing lots of QA/QC-type/GMP positions; something tells me that this is a temp/recruiting service that hires international folks only?I'm confused.(Hey, check out their partners - including the "Havard Clinical Research Institute." Something is very fishy here.)

1:35 PM | Optical features embedded in marine shells may help develop responsive, transparent displays (w/video)
New findings represent the first evidence of an organism using mineralized structural components to produce optical displays. While birds, butterflies, and beetles can display brilliant blues, among other colors, they do so with organic structures, such as feathers, scales, and plates. The limpet, by contrast, produces its blue stripes through an interplay of inorganic, mineral structures, arranged in such a way as to reflect only blue light.
