JAAS and the Mars Curiosity Rover

Study of rock identification at the surface of Mars by LIBS

The paper by Sirven et al. featured on the front cover of JAAS, 2007, Issue 12

Back in 2007, we published a paper in JAAS about the LIBS analysis that would be used to identify rocks during an upcoming mission to study Mars. Now, the ChemCam instrument is an operational part of the Mars Science Laboratory on the Curiosity mission, helping to achieve its four goals:

  • Determine whether life ever arose on Mars
  • Characterize the climate of Mars
  • Characterize the geology of Mars
  • Prepare for human exploration

Take a look at the paper, which will be free to access until 30 September 2012 to see why the combination of two chemometric approaches mean a higher level of analytical accuracy:

Feasibility study of rock identification at the surface of Mars by remote laser-induced breakdown spectroscopy and three chemometric methods
Jean-Baptiste Sirven, Béatrice Sallé, Patrick Mauchien, Jean-Luc Lacour, Sylvestre Maurice and Gérard Manhès
J. Anal. At. Spectrom., 2007,22, 1471-1480
DOI: 10.1039/B704868H

Want to know more about this mission to the Red Planet? We will be gaining insight from one of the drivers of the Curiosity rover live this Friday. Paolo Bellutta works at NASA’s Jet Propulsion Laboratory and he will join us live from Pasadena on Friday 7 September at 16:00 BST for a question-and-answer session to be broadcast on the RSC YouTube channel.

Arsenic-resistant bacterium still needs phosphate for growth

A paper co-authored by JAAS Editorial Board Chair, Detlef Günther has been published in Science and contributes to an ongoing discussion on the role of arsenic in the bacterial isolate GFAJ-1.

In December 2010, Felisa Wolfe-Simon and colleagues published a paper, also in Science, which proposed that GFAJ-1 could substitute small amounts of phosphorus in its DNA with arsenic. This claim would have significant implications for our understanding of life, since all known forms of life on Earth typically use oxygen, carbon, hydrogen, phosphorus and sulfur.

This new work from Detlef and fellow researchers at ETH Zürich shows that GFAJ-1 is able to grow at low phosphate concentrations even under high arsenate concentrations, but cannot grow in phosphorus-depleted, arsenate-containing medium. They combined physiological experiments with ICP-OES and ICP-MS to provide evidence that whilst GFAJ-1 is highly resistant to arsenate, but still requires phosphate for growth. The authors say that the molecular basis for arsenate resistance in GFAJ-1 could be the subject of further investigations.

GFAJ-1 Is an Arsenate-Resistant, Phosphate-Dependent Organism
Tobias J. Erb, Patrick Kiefer, Bodo Hattendorf, Detlef Günther, Julia A. Vorholt
DOI: 10.1126/science.1218455

Also published in Science is a paper from Rosie Redfield and colleagues at Princeton University, which supports the conclusions from the ETH group:

Absence of Detectable Arsenate in DNA from Arsenate-Grown GFAJ-1 Cells
Marshall Louis Reaves, Sunita Sinha, Joshua D. Rabinowitz, Leonid Kruglyak, Rosemary J. Redfield
DOI: 10.1126/science.1219861

Though not quite as controversial, take a look at some recent content in JAAS on arsenic:

2011 R&D100 Award Winners

R&D Magazine recently announced the 2011 R&D100 award winners, and this year’s awardees included several names familiar to JAAS readers.  The “Array Detection Technology for Mass Spectrometry” was identified as one of the 100 most influential technological achievements/products of the year.

The award-winning technology comes from a collaboration between government, academic, and private sector entities:

  • Pacific Northwest National Laboratories (Charles Barinaga and David Koppenaal)
  • Indiana University (Gary Hieftje, James Barnes, Greg Shilling, Jeremy Felton, and Steven Ray)
  • University of Arizona (M. Bonner Denton and Roger Sperline), Imager Laboratories (Gene Atlas)
  • SPECTRO Analytical Instruments/Ametek (Dirk Ardelt)

The array detector (also known as the Focal Plane Camera) is a solid-state monolithic integrated circuit device designed specifically as adetector for mass spectrometry. It was first employed for atomic mass spectrometry (ICP-MS), but has more recently found other uses in ion mobility spectrometry and molecular mass spectrometry.  A commercial version of the detector can be found in the new SPECTRO MS instrument.

Since 1963, the R&D 100 Awards have identified revolutionary technologies newly introduced to the market.  The Awards, widely recognized as the “Oscars of Innovation”, identifies and celebrates the top high technology products of the year.

More information can be found here.

Congratulations award winners!

7 great reasons to download the RSC Mobile App…

Martín Resano, JAAS Editorial Board member, provides an introduction to the new RSC mobile app, and some tips for how it can help you to stay in touch with the latest research from RSC journals

The RSC has made available a mobile App that permits access to more than 30 journals from the RSC publishing platform. The application entitles all iPhone/iPad/iPod touch users to follow the RSC Journals in which they are interested in a very simple way. As illustrated in the screen captures attached (from an iPhone), the App provides fast access to the latest articles of the selected Journals, which can be saved (as pdf or html) for off-line reading, or just shared with colleagues via Facebook, Twitter or e-mail, all with a single click. Moreover, there is also a fast search engine, such that all the on-line content of RSC Journals can be thoroughly explored.

In order to benefit from all these features, the users need to be connected to a wireless network from a subscribing institution/organisation (otherwise, only abstracts and not the full version of the papers will be visible). However, more forms of authentication will be implemented soon. An Android version is also expected to be available in early 2012.

Users who have an RSC Publishing personal account however can use this app to access all the free content available, without the need for a subscription!

The App is free and can be downloaded from the iTunes store: http://itunes.apple.com/gb/app/rsc-mobile/id459371444?mt=8
