The Newscripts blog would like to be closer Internet buddies with our glossy print Newscripts column, so here we highlight what’s going on in the current issue of C&EN.
As the cashier at the fast-food restaurant is finishing our order, she grabs a small plastic doll and tosses it in my kids’ meal.
“Excuse me,” my mom says testily. “You didn’t give my daughter a choice of toys.” Even at age six, I can tell my mom is using tremendous restraint to give this young woman a chance to rectify her unintentional wrongs.
The woman looks at my mom, then at me, and asks, “Well, do you want the girls’ toy or the boys’ toy?”
I don’t remember if I ended up picking the doll or the toy car on that particular occasion. But I do distinctly remember the feeling of trying to weigh the gaps in my own eclectic toy collection with the point my now-fuming mother was trying to teach both me and the young woman at the cash register. Toys are toys, and kids should be able to choose their own interests without feeling undue social, gender-specific pressure.
Twenty years later, I call my mom and tell her about this column, and she’s outraged we’re still having this debate. As I write in Newscripts this week, the gender-specific labeling of toys came under fire in England recently. Specifically, customers and online advocacy group Let Toys Be Toys took issue with science kits and chemistry sets being designated for boys. Since the backlash, toy giant Tesco and pharmacy chain Boots have changed their girls- and boys-specific toy labeling and issued apologetic statements.

When Ernest O. Lawrence lent a cyclotron to the London Science Museum in 1938, he thought it would be back in eight months.
But it took 75 years for the 11-inch cyclotron, one of the first built by the future Nobel Prize winner, to return to the hills of Berkeley, Calif., where it was originally created.
The cyclotron survived a war, a bureaucratic tussle, and a security challenge before it was finally returned to Lawrence Berkeley National Laboratory (LBNL), the research institution founded by the cyclotron’s inventor.
When it arrived last month, the 11-inch cyclotron was an instant celebrity, drawing crowds as though Lawrence himself had walked in for a photo op.
“They were coming down the hallway in a stream,” says Pamela Patterson, who serves as an unofficial historian and manager of the lab’s website. “Everyone was there. The director had his iPhone up taking pictures. It was cute.”
At the time Lawrence loaned the cyclotron to the science museum, he was still a young, ambitious researcher trying to convince others that the device was a major breakthrough. An invitation to display it in such a prestigious spot was likely an important step, Patterson explains.
But when the cyclotron was supposed to be returned in 1939, Lawrence received a letter from the museum saying officials had moved the cyclotron to a rural district for safe keeping because they feared London would be bombed during World War II. Continue reading →
The seven-year relationship of two physicists has moved to the next level, thanks to a marriage proposal Brandon wrote to Christie in the form of a physics paper. The faux academic article, titled “Two Body Interactions: A Longitudinal Study,” is dated March 2012, but hit Reddit‘s cyberspace – and achieved cyber fame — at the end of last month.
The paper discusses how they met: “The study began on the 23rd of March, 05, outside a SciSoc BBQ at the Eastern Avenue Building, when the subject spontaneously appeared in a red coat and a grey ‘Paddington bear’ hat and was similarly spontaneously introduced by a local social node.”
It then goes on to explain the stresses that tested the long-distance relationship between Brandon and Christie: “The locational dependence of the results was tested across two main long term locations as well as a multitude of short term locations local, interstate, and international.”
And finally how they moved in together: “The third phase of the study involved isolating the two body interaction in a new long term location, while continuing the above mentioned tests.”
The paper even includes a graph of happiness over time, with a predicted upward trend in the happier-as-time-goes-on direction.
And for the paper’s conclusion …
In this week’s issue of C&EN, I wrote about how 3-D printing fever has taken hold of some folks in academia. Sure, scientists and engineers COULD keep a 3-D printer in the lab strictly for printing out a molecular model, a prototype, or even an intricate lab logo. But they’re starting to do much more with the machines.
As Lee Cronin, a chemist at Scotland’s University of Glasgow, told me, in the early days of 3-D printing, “people thought it was cool but gimmicky.” Now, though, they’re beginning to use the technique to solve problems, he added.
In the story, I describe how some scientists have used 3-D printers to make lab equipment such as centrifuges, funnels, lab jacks, and electrophoresis gel combs. These early adopters claim that the machines, which build solid objects layer by layer from materials like plastics and ceramic powders, can save labs thousands of dollars. And, they say, 3-D printers help foster an open-access scientific community that will speed the progress of research.
One research group I didn’t get to mention in my story is that of Simon J. Leigh, a chemist-turned-engineer at the U.K.’s University of Warwick. Leigh and his team are developing new materials for 3-D printers, with the goal of eventually incorporating them into devices for the lab and beyond.
For instance, late last year, the researchers published a PloS One paper detailing how they concocted “carbomorph,” a material made of the thermoplastic polycaprolactone and 15 wt% carbon black. “The aim of the project was to develop a material that could go into a printer that’s off the shelf,” Leigh says. In addition to being electrically conductive, carbomorph had the added benefit of being extrudable by a standard low-cost 3-D printer (they used a Bits from Bytes 3000).
Leigh’s team demonstrated that the substance could also be incorporated into several devices. One of these instruments was an electronic interface. The researchers added carbomorph buttons to an electrical circuit: When a user pressed one of them, its capacitance increased and triggered an electrical signal. Being able to embed sensors like these anywhere on a device rather than adding them on at defined spots in post-production could be extraordinarily useful, Leigh says.
In one, perhaps gimmicky, example, Leigh and his team printed sensor buttons into a video-game controller. “But there’s no reason why the same process could not be used to make custom interfaces for scientific equipment,” he says.
In 2011, the research team also developed a magnetic material for 3-D printing that it used to manufacture a flow sensor. Specifically, the scientists added magnetite nanoparticles to a resin matrix and printed a tiny rotor (impeller). By monitoring the small piece’s rotational speed via external magnetic field, the researchers were able to determine the speed of liquid across it.
Why go to all the trouble of designing new materials and printing devices you could buy? Leigh says it’s almost a natural “evolutionary step.” First, there were desktop computers, next there will be desktop manufacturing systems. In science, especially, Leigh adds, “you want something that’s more bespoke these days. You don’t want to waste material or time” to get the equipment you need.
It only takes some YouTubers being in the right place at the right time to prove how ridiculously far owls can rotate their heads — up to 270 degrees in either direction, in fact. But it took a team of neurological imaging experts and medical illustrators to figure out both how this flexibility feat is anatomically possible and how to effectively illustrate it.
The Johns Hopkins University team took first place in the poster and graphics portion of the International Science & Engineering Visualization Challenge competition, which was sponsored by Science magazine and the National Science Foundation. Led by medical illustrator Fabian de Kok-Mercado, now at Howard Hughes Medical Institute, the team used angiography, X-ray imaging, and CT scans to study the bone structure and vasculature of the heads and necks of snowy, barred, and great-horned owls.
Their study shows that owls’ transverse foramina–the holes in the vertebrae that allow arteries to line the spine–are much larger than the blood vessels, allowing more wiggle room for twisting and turning. And they found blood-pooling mechanisms and backup arteries that help direct blood to the brain when the main arteries are pinched in the turning process.
The People’s Choice award in the same posters and graphics portion of the competition goes to designers who are likely SimCity fans. Or perhaps it was the voters who are fans of the city-building video game series? We digress. A team from the European Centre for Environment & Human Health at the University of Exeter Medical School and Plymouth University designed an entire town to represent possible routes to sustainable pharmaceutical use: Continue reading →
Most scientists end up having two families. The first is the one they are born or adopted into. But the second, the lab family, can be every bit as important. I’ve been fortunate to connect with “lab family” members who never overlapped with me at the benchtop, but who share a sense of camaraderie because of our shared mentors. In fact, I credit one of my Sorensen lab siblings, Lucy Stark, with helping me make the “alternative career” connections that put me where I am today.
Robert J. Lefkowitz, who took home half of the 2012 Nobel Prize in Chemistry, has both kinds of family in spades. At a Duke press conference, colleagues extolled his talents as a teacher and mentor to hundreds of scientists, including his fellow laureate Brian Kobilka. Intrepid Terra Sig blogger, David Kroll, who had an excellent post about the chemistry Nobel on Wednesday morning, ventured to Duke to capture the celebrations with Lefkowitz’ lab family. (Thank you, David, for sharing your photos!)
And via Twitter, I learned about the reaction to the prize from a member of Lefkowitz’ outside-the-lab family: his daughter, Cheryl Renée Herbsman (née Lefkowitz), an author.
Wow, just found out my dad won the Nobel Prize in chemistry! cnn.com/2012/10/10/wor…
— Cheryl Herbsman (@cherylherbsman) October 10, 2012
I emailed Herbsman a few questions, which she was gracious enough to answer. I’ve lightly edited this exchange for grammar and content.
CD: Growing up, what kinds of things did you hear from your father about what he worked on?
CRH: Growing up, I don’t think my siblings and I necessarily understood what our father was researching. We knew it had to do with receptors, but that might have been the full extent of our understanding. Sometimes he would talk at dinner about whether the research was going well or not. Occasionally he would take us to the lab with him on a Saturday morning, where we would have wheeled desk-chair races and explore the walk-in refrigerators. Often, we would hear him dictate papers into his Dictaphone. The words didn’t mean much to us. But I remember my younger sister writing up “scientific papers” of her own with a lot of important-sounding made-up words. My dad always ended the dictation by saying, “RJL etc.” So my sister ended hers with her initials, etc., as well.
How much did you and your siblings realize how well-known your dad’s work was? Did you have any idea he might win a Nobel Prize someday?
When we were kids we didn’t realize how important his research would become. But as we got older, and he began winning more recognition for his work, it became more and more clear how much his work mattered. All of us, and my children as well, were lucky enough to attend the ceremony at the White House when he received the National Medal of Science.
Did your dad’s science career have any effect on your relationship with science in school and in life? How so?
I don’t know if it affected my relationship with science. He never pressured any of us to follow in his footsteps. But I think his dedication to his work taught me to work hard, to hang in there when things weren’t going the way I wanted them to, and to never give up.
In the acknowledgements for your novel, “Breathing”, you mentioned your father’s support. That’s interesting to me because others have been talking today about your father’s skills as a mentor. What about your dad do you think makes him a good advice-giver or giver of support?
He has always been someone who can think things through rationally, so he made a great sounding board. He was able to keep his own opinions out of the equation, so he could help us figure out what it was we really wanted to do. He has a way of being reassuring in stressful times, staying calm, trusting that things will work out. In addition, he always encouraged me to go after my dreams. He made me believe that with enough determination I could make them reality.
Is it true you babysat for Brian Kobilka’s kids?
I did babysit for Brian Kobilka’s kids for a week one summer when they needed childcare. I remember watching Nickelodeon with them and making Rice Krispie Treats.
What do you most want the world to know about your dad?
He is a dedicated and passionate man who truly loves what he does. He has often told me that he feels very fortunate that work to him is like play, and some days he can’t believe they pay him to do it. He said he thought this was one of life’s great secrets – that is, to find work one truly loves.

The American Chemical Society meeting in Philly is now fading into our long-term memories. Chemists accomplished a lot in the City of Brotherly Love: They shared ideas, reported their chemical discoveries, and made new connections. Be sure to check out Monday’s issue of C&EN for stories from the meeting as well as photo highlights. In the meantime, here’s a look back on our time in Philly, told in pictures.
And as we say goodbye to Philly, we look toward next spring’s gathering in New Orleans. The beleaguered region and its residents once again have a cleanup ahead of them, after facing Hurricane Isaac. Our hearts go out to everyone there who is dealing with the consequences of this natural disaster–it reminds us just how fragile life can be.
