6:57 AM | Breakthrough in light sources for new quantum technology
One of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons (electronic circuits). First, it is necessary to create a stream of single photons and control their direction. Researchers around the world have made all sorts of attempts to achieve this, but now scientists have succeeded in creating a steady stream of photons emitted one at a time and in a particular direction.

4:11 AM | Publication of the week, number 40, 29th August 2014
The synthesis of olefins belongs to the fundamental group of organic chemistry methods. Lots of ways are available to achieve olefin synthesis, the Wittig reaction and the phosphonate equivalent, the Horner-Emmons reaction, are amongst the most utilised in synthesis. Now these methods are not catalytic, they utilise strongly basic conditions, which may cause problems elsewhere […]

8:12 PM | The Dark Net – Jamie Bartlett
From the blurb: “Beyond the familiar online world that most of us inhabit – a world of Google, Hotmail, Facebook and Amazon – lies a vast and often hidden network of sites, communities and cultures where freedom is pushed to its limits, and where people can be anyone, or do anything, they want. A world […]The Dark Net – Jamie Bartlett is a post from the science blog of science journalist, photographer and musician David Bradley Subscribe to our Email […]

7:45 PM | Using nanotechnology to regulate gene expression at the transcriptional level
Gene transcription is tightly regulated by proteins called transcription factors. These transcription factor (TF) proteins are master regulators of transcriptional activity and gene expression. Transcription factors are responsible for transcribing the correct genes and therefore for producing the right quantity of proteins. TF-based gene regulation is a promising approach for many biological applications, however, several limitations hinder the full potential of TFs. To overcome these […]

7:28 PM | Watching the atomic structure of glass under pressure
Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structure of glass. Now researchers have for the first time captured atoms in borosilicate glass flipping from one structure to another as it is placed under high pressure.

5:39 PM | Summers End
The air around Keele has been distinctly Autumnal of late, and in between heavy rain, it’s quite clear that summer is done. Hopefully we’ll get an Indian summer for those last few rays of hope before the season properly turns. … Continue reading →

3:33 PM | Oranges and Lemons
Guest post by Rowena Fletcher-Wood Scurvy plagued early sailors, and although many treatments were tried and promoted, a simple cure was masked for centuries behind a series of mistakes and misunderstandings. The This story begins at sea, long into a voyage after the fresh food stock had long run out and the sailors were left [...]

8:06 AM | Materials other than silicon for next generation electronic devices
Silicon has been the most successful material of the 20th century, with major global industries and even a valley named after it. But silicon may be running out of steam for high performance/low power electronics. As silicon strains against the physical limits of performance, could a material like InGaAs provide enough of an improvement over silicon that it would be worth the expense in new equipment lines and training to make the switch worthwhile?
