The Editors of The Journal of Experimental Biology are pleased to announce that Dr Nicole George is the winner of this year's JEB Outstanding Paper Prize. Awarded in memory of Bob Boutillier (JEB Editor in Chief 19942003), the prize recognises the junior author who made the most significant contribution to an outstanding paper. Explaining that the winning paper was selected by the Editors from a short list of eight articles (available at the end), Hans Hoppeler JEB Editor-in-Chief adds, 'The Outstanding Paper Prize showcases the kind of research that we love best at the journal.' The announcement is made in issue 24 of volume 215 of the Journal at http://jeb.biologists.org.

George published her award-winning paper, 'Temperature gradients drive mechanical energy gradients in the flight muscle of Manduca sexta' with Simon Sponberg and Tom Daniel in the third issue of 2012 (George, et al. 2012). Considering the current winner, Hoppeler says, 'The journal's editorial policy asks for hypothesis driven research aimed at elucidating novel physiological principles and Nicole George's article falls exactly into that category'.

Describing her reaction to the news, George says, 'I was surprised, definitely it was very exciting, it's a paper that's dear to my heart but you never know how other people feel about it so this was confirmation that this is exciting science'. And Hoppeler comments, 'This article stands out because it shows that a physiological system that everybody seems to understand, the flight muscle of Manduca sexta, behaves in a complex fashion based on physical constraints that had not been taken into account previously'.

George joined the Daniel lab in 2008 after majoring in integrative biology at University of California Berkeley, USA. After spending a year in Mimi Koehl's lab as a post-baccalaureate research assistant, George says, 'It was wonderful because it gave me the experience I needed to know that I really wanted to go into this field as a grad student'. Having joined Daniel's University of Washington Lab, she was also awarded a prestigious National Science Foundation Graduate Research Fellowship. Explaining that the success rate for applicants is extremely low, Daniel says, 'The NSFGRF program gives students an amazing amount of freedom to pursue research that isn't tied to an existing grant'. And George grasped this opportunity with both hands. Daniel recalls, 'When Nicole joined my lab she said, "I don't want to just do a dotting 'i' and crossing 't' type of project, I want to do something where there is a conceptual advance", and we had this temperature gradient in Manduca muscle as a back-burner project and that is where Nicole took off'.

'The concept of a temperature gradient arose from the idea that if you have a muscle contracting and producing heat with convective cooling on the surface then presumably there should be a temperature gradient throughout the muscle', explains George. 'I started the thesis by really honing in on whether the temperature gradient exists' she adds. Measuring the temperature at a series of locations in the main flight muscles (the dorsolongitudinal muscles) of tethered flying Manduca sexta, George measured a 5.6C temperature difference between the top and bottom of the flight muscle because the muscle segments in the insect's back were cooled by the passing air flow. And when George measured how the top and bottom portions of the muscle contracted at the same temperature, she could see that both sections contracted at the same rates. However, the rates of contraction differed significantly when the portions were at different temperatures, forcing the cooler sections to contract at a lower rate than the warmer sections, suggesting that the cooler top segments would produce significantly less mechanical power (George and Daniel, 2011). In other words, a muscle with a temperature gradient could serve multiple functions.

Intrigued by the physiological implication, George embarked on stage two of her thesis. 'We wanted to look at what consequence this would have for mechanical power output as a function of the muscle temperature, and that is what led to the 2012 paper', she says. Working with postdoc Simon Sponberg, George ironed out all of the technical challenges that she faced before measuring the power generated by the muscle over temperatures ranging from 25 to 40C. She found that the muscle produced impressive power outputs in the region of 100 W kg1 at the highest temperatures. However, as the temperature dropped, so too did the power output, until at 30C, the power output became negative. The cool muscle was either storing or absorbing energy; which didn't make sense. 'It doesn't help the moth to fly,' says George. And when she repeated the experiments with the top and bottom sections of the muscle, she found that the warm bottom segment which produces positive power could power flight by pulling on the thorax cuticle to push the wing down during the first half of the wing beat. However, the cooler slowly contracting top segment could be acting as a damper to stabilize the system or as an elastic energy storage system to help raise the wing during the relaxation portion of the contraction cycle at the end of a downbeat. 'All at once you have multiple functions within one single muscle because of the temperature gradient', explains George.

Outlining George's commitment to the demanding work, Daniel says 'I have a slide about every student that defends their thesis in my lab that has three words that I think characterise the student, and the three words for Nicole are; diligence, focus and creative spark'. Giving an example of her impressive work ethic, Daniel describes George's ability to focus, regardless of distraction. 'Nicole would come into the lab and you know, you have the usual coffee clutch around but Nicole walks up and she just starts working'. He adds, 'But all the focus in the world isn't useful if there isn't a creative spark there, and Nicole has that too'.

Following on from her thesis research, George is continuing her work in Daniel's lab as a postdoc where she is preparing to analyse the muscle structure of tethered moths in flight using X-ray diffraction at the Argonne National Laboratory. However, George's career choice is not quite as conventional as it might at first seem. George says, 'I have always enjoyed science and I want to continue working in science but I have always been interested in how to enact change on a global level and how science can be used to do that'. This led her to take the summer out from research and accept an internship at the Paul G. Allen Family Foundation, a philanthropic organisation supporting a wide range of community and environmental projects in the Pacific Northwest. However, since returning to the lab, George has maintained contact with the foundation, where she is continuing to advise their scientific program. 'I am looking at the field of ocean health, analysing opportunities for success. It's very fun and I get to learn a lot of new things', George smiles.

Chemical biology: DNA's new alphabet

Posted on by

When Steven Benner set out to re-engineer genetic molecules, he didn't think much of DNA. The first thing you realize is that it is a stupid design, says Benner, a biological chemist at the Foundation for Applied Molecular Evolution in Gainesville, Florida.

Take DNA's backbone, which contains repeating, negatively charged phosphate groups. Because negative charges repel each other, this feature should make it harder for two DNA strands to stick together in a double helix. Then there are the two types of base-pairing: adenine (A) to thymine (T) and cytosine (C) to guanine (G). Both pairs are held together by hydrogen bonds, but those bonds are weak and easily broken up by water, something that the cell is full of. You're trusting your valuable genetic inheritance that you're sending on to your children to hydrogen bonds in water? says Benner. If you were a chemist setting out to design this thing, you wouldn't do it this way at all.

Life may have had good reasons for settling on this structure, but that hasn't stopped Benner and others from trying to change it. Over the past few decades, they have tinkered with DNA's basic building blocks and developed a menagerie of exotic letters beyond A, T, C and G that can partner up and be copied in similar ways. But the work has presented one goddamn problem after another, says Benner. So far, only a few of these unnatural base pairs can be inserted into DNA consecutively, and cells are still not able to fully adopt the foreign biochemistry.

The re-engineering of DNA, and its cousin RNA, has practical goals. Artificial base pairs are already used to detect viruses and may find other uses in medicine. But scientists are also driven by the sheer novelty of it all. Eventually, they hope to develop organisms with an expanded genetic alphabet that can store more information, or perhaps ones driven by a genome with no natural letters at all. In creating these life forms, researchers could learn more about the fundamental constraints on the structure of genetic molecules and determine whether the natural bases are necessary for life or simply one solution of many. Earth has done it a certain way in its biology, says Gerald Joyce, a nucleic-acid biochemist at the Scripps Research Institute in La Jolla, California. But in principle there are other ways to achieve those ends.

Benner first became interested in those other ways as a graduate student in the 1970s. Chemists had synthesized everything from peptides to poisons, and some were trying to build molecules that could accomplish the same functions as natural enzymes or antibodies with different chemical structures. But DNA was largely ignored, he recalls. Chemists were looking at every other class of molecule from a design perspective except the one at the centre of biology, says Benner.

In 1986, Benner started a lab at the Swiss Federal Institute of Technology in Zurich and began to rebuild DNA's backbone. He quickly realized that what seemed like a flaw might be a feature. When he and his team replaced the backbone's negatively charged phosphates with neutral chemical groups1, they found that any strand longer than about a dozen units folded up on itself probably because repelling charges were needed to keep the molecule stretched out.

The bases proved more amenable to tinkering. Benner set out to create base pairs that are similar to nature's, but with rearranged hydrogen bonding units.

His team tested two new pairs: iso-C and iso-G (ref. 2) and and xanthosine3. It showed that polymerase enzymes which copy DNA or transcribe it into RNA could read DNA containing the unnatural bases and insert the complementary partners into a growing DNA or RNA strand. Ribosomes, the cellular machines that 'translate' RNA into protein, could also read an RNA snippet containing iso-C and use it to add an unnatural amino acid to a growing protein4. The base pairing, which is at the centre of genetics, turned out to be for us the most malleable part of the molecule, says Benner. The researchers did encounter a problem, however. Because its hydrogen atoms tend to move around, iso-G often morphed into a different form and paired with T instead of iso-C.

Eric Kool, a chemist now at Stanford University in California, wondered whether his team could develop unnatural bases with fixed hydrogen-bonding arrangements. He and his colleagues made a base similar to the natural base T, but with fluorine in place of the oxygen atoms (see 'Designer DNA'), among other differences5. The structure of the new base, called difluorotoluene (designated F), mimicked T's shape almost exactly but discouraged hydrogen from jumping.

The team soon discovered that F was actually terrible at hydrogen bonding5, but polymerases still treated it like a T: during DNA copying, they faithfully inserted A opposite F (ref. 6) and vice versa7. The work suggested that as long as the base had the right shape, a polymerase could slot it in correctly. If the key fits, it works, says Kool.
