Decoding interstellar carbon
25 Apr 2014
Rachel Wood writes about a hot Chemical Science article for Chemistry World
For over 20 years the infrared spectra of many astronomical objects have been interpreted as flat two-dimensional polycyclic aromatic hydrocarbons (PAHs) that are also thought to be the source of organic matter on our own planet. More recently the detection of molecules such as fullerenes – molecules composed entirely of carbon, including the spherical C60 – has revealed a more complicated picture of carbon in space. The links between these different molecules have been rather unclear but new research from Héctor Alvaro Galué at VU University of Amsterdam, in the Netherlands, has taken a fresh approach to this long-standing puzzle.

DNA cube programmed for an exclusive reveal
16 Apr 2014
Jennifer Newton writes about a hot Chemical Science article for Chemistry World
Scientists in Canada have made DNA cubes that are programmed to unzip and reveal molecules locked inside them in response to a carefully chosen trigger. Hanadi Sleiman and colleagues at McGill University and the Jewish General Hospital in Montreal, designed the cubes to release the drug cargo they might be carrying only in diseased cells and not normal cells.
The mRNA trigger binds tothe overhangs and opens the cube by strand displacement and strategically placed nicks on the structure

Two stories from ISACS 12: solar-fuel devices and catalyst identification
09 Apr 2014
The April issue of our sister journal Energy & Environmental Science opens with an editorial on the ISACS 12 conference held in Cambridge last September. Nathan Lewis, Chair of the EES editorial board, and co-authors report on highlights of the symposium and discuss two of the main topics covered at the meeting: solar-fuel generators and identifying catalysts.

Four steps to asthma treatment
19 Mar 2014
Eleanor Merritt writes about a hot Chemical Science article for Chemistry World
Montelukast works by blocking the action of chemicals released by the body as part of allergic and inflammatory reactions
Scientists based in the US have devised a new way to make Montelukast, a drug used in the treatment of asthma and seasonal allergies.
Asthma is a chronic inflammatory disease of the airways which affects up to 300 million people worldwide and caused 250,000 deaths in 2011. Although there is no cure for asthma, symptoms can be managed through the use of fast-acting medication to treat acute attacks, and long-term control achieved using inhaled corticosteroids, sometimes in conjunction with a leukotriene antagonist, such as Montelukast.

Chemical Science welcomes Zhenan Bao as Associate Editor
14 Mar 2014
This month, Chemical Science is delighted to welcome Zhenan Bao as Associate Editor in the area of organic materials. Zhenan received her PhD from the University of Chicago in 1995, and after a spell at Lucent Technologies’ Bell Labs, joined the Department of Chemical Engineering at Stanford University in 2004. She was appointed to her present position as Professor in 2012.
Zhenan was awarded the Beilby Medal and Prize by the Royal Society of Chemistry in 2009, for her contributions and discoveries in the field of organic semiconductors. These included demonstrating that conjugated polymers can produce high mobilities of charge carriers when self-assembled using solution deposition.
She also featured in Thomson Reuter’s ‘Top 100 Materials Scientists’ report in 2011, which identified researchers with the highest citation counts for papers published in 2000–2010.
The Bao Group’s research utilizes the basic principles in chemistry, physics and material sciences to enable novel applications and development of flexible, stretchable electronics and energy devices. Current research projects within the group include organic semi-conductor design, organic and carbon solar cells, and electronic skin.
The group has published work in a number of Royal Society of Chemistry journals, and you can read more about it in the following articles:
