ScienceOnline 2011 is over and the daze of normality resumes. It’s hard to describe the feeling to people who have never been to the conference. Put it this way: you spend four days in a mental endurance event set in a parallel universe that’s largely similar to this one, except for the fact that all conversations are interesting.
As I said last year, ScienceOnline was a valuable chance to meet friends for the first time. It gave us a chance to take relationships that had begun on a screen and cement them in the flesh. It allowed us to trade ideas with like-minded people, and to gaze deeply into our navels so that we can do better at the things we love. As someone said on Twitter, it’s more like a family reunion than a conference.
The sessions were consistently great and the unconference format works wonders. Even when I wasn’t a panellist, I felt no less involved in the sessions I attended. (I’ll stick some write-ups later after catching up with regular blogging and I’ll collate some links to what others write.)
Some people have criticised Scio11 for selling out so quickly, with the implication that it must cater for a cliquey audience. But many of the delegates were first-timers; at least half of the people I talked to weren’t there last year. The reason why ScienceOnline is so successful is that the people who are there are the ones who really want to be. They regularly engage with the online community, they take part in discussions throughout the year, and they are ready and waiting to sign up. This doesn’t weaken the conference; it makes the conference. It creates a fantastic grassroots, everyone-mucking-in atmosphere. It’s a conference by the community for the community. I wouldn’t want it any other way.
Most inspiring moment: The keynote speech from Robert Krulwich from NPR’s RadioLab, who combines storytelling, sound effects and humility into a singular type of aural poetry. Inspiring and depressing in equal measure, the talk was a great reminder of how far I have yet to go.
Biggest fanboy moment: The aforementioned Robert Krulwich (him again?) came up to me after the Friday night dinner and told me that he reads this blog and really likes it. Outside, I was the epitome of smooth gratitude. Inside: crazy happy skippy dance. <waves at Robert>
Most startling moment: During the visit to the Duke Lemur Center, I can only assume that I antagonised one of the ruffed lemurs in some way because with no warning, it started making an alarm call that sounded like a sonic nuke going off in a narrow echoing corridor. “Show us on the lemur doll where the science writer touched you…”
Best souvenir: An awesome It’s Only Rocket Science mug that Karen James bought for me from the Kennedy Space Center.
Autograph score: Three. I have signed copies of Written in Stone by Brian Switek, Superbug by Maryn McKenna and The Science of Kissing by Sheril Kirshenbaum.
Best opening line to a conversation I walked into: “Why does Chewbacca have a crossbow?”
Worst opening line to a conversation I walked into: “We’re discussing Noam Chomsky.”
Once again, I am utterly indebted to Bora Zivkovic and Anton Zuiker for giving me the chance to take part and for putting their blood, sweat and tears into making such an incredible event.
And finally, it was great to catch up with old friends and colleagues, to put some new faces to familiar names. For their amicable chat and great company, I thank Carl Zimmer, SciCurious, David Dobbs, Alice Bell, Sheril Kirshenbaum, Christie Wilcox, Janet Stemwedel, John Rennie, Kaitlin Thaney, Maryn McKenna, Virginia Hughes, Steve Silberman, David Kroll, Brian Switek, Ivan Oransky, Hillary Rosner, Emily Anthes, Tom Levenson, Amos Zeeberg, Richard Grant, Jenny Rohn, Alok Jha, Liz Neeley, Arikia Millikan, DeLene Beeland, Sophia Collins, Karen James, Clifton Wiens, Kate Clancy, Seth Mnookin, Carmen Drahl, Colin Schultz, Jason Goldman, Christine Russell, Andrea Kuszewski, Olivia Koski, Hannah Waters, Craig McClain, Kevin Zelnio, Miriam Goldstein, Joanne Manaster, Marie-Claire Shanahan, John Timmer, Chris Rowan, Lucas Brouwers, Brian Mossop, Glendon Mellow, , James Hyrnyshyn, Jag Bhalla, Taylor Dobbs, Jamie Vernon, Robert Krulwich, Tyler Dukes, Catherine Anderson, Dan Ferber, Robin Lloyd, Tim de Chant, Paul Raeburn, Mark Hahnel, Scott Rosenberg, Diane Kelly, Matt Soniak, Amanda Moon, Eric Michael Johnson, Dave Mosher, John Logsdon, Nancy Shute, Zuska, Catherine Zivkovic, Chris Mooney, Peter Janiszewski, Emily Finke,Allie Wilkinson, Viv Raper, Dave Munger, Josh Rosneau, Misha Angrist, David Orr, Melody Dye, Greg Gbur, Lisa Jarvis, Holly Bik, Stacy Baker, Carin Bondar, John Hawks, Brian Malow, Mike Lisieski, Jeremy Yoder, Jim Hutchins, Psi Wavefunction, Holly Tucker, Walter Jessen, Steve Mirsky, Emily Willingham, Maia Szalavitz, Lyndell Bade, Robert Mitchum, Karyn Traphagen, Michael Barton, Pascale Lane, Jason Thibeault, Krystal D’Costa, Rhitu Chatterjee, Darlene Cavalier, Lou Woodley, Stephanie Zvan, David Shiffman and the many, many other people who I’ve undoubtedly forgotten because it’s late and I’m jetlagged. If I have forgotten you, you’re probably called Emily or John.

In the wild, you may occasionally see a penguin wearing a metal band around the base of one of its flippers. These bands aren’t the latest in penguin bling – they’re tools used by scientists to track the lives and movements of individuals. The bands are controversial – some say that they are innocuous, while others argue that they slow and hurt the very birds that scientist are trying to conserve. Now, Claire Saraux from the University of Strasbourg has evidence that might swing the debate – a ten-year study showing that banded birds die sooner and raise fewer chicks.
It’s winter on a British meadow, and a red fox is on the prowl. The snow-covered ground masks the sight of its prey but the fox can still hear the telltale rustle of a mouse. It creeps forward slowly, listening intently with erect ears. Once it pinpoints the mouse’s location, it leaps into the air to surprise its prey with a strike from above. This pounce, known as ‘mousing’, is a common sight but there’s more to it than meets the eye. Jaroslav Červený has found that when red foxes pounce, they mostly jump in a north-easterly direction. He thinks that they’re using the Earth’s magnetic field to hunt.
Červený spent over two years studying wild red foxes in the Czech Republic, with the help of a 23-strong team of wildlife biologists and experienced hunters. The team recorded almost 600 mousing jumps, performed by 84 foxes at a wide variety of locations and times.
They found that foxes strongly prefer to jump in a north-easterly direction, around 20 degrees off from magnetic north. This fixed heading was important for their success as hunters. They were more likely to make a kill if they jumped along their preferred axis, particularly if their prey was hidden by high cover or snow. If they pounced to the north-east, they killed on 73% of their attacks; if they jumped in the opposite direction, they success rate stayed at 60%. In all other directions, only 18% of their pounces were successful.
On Thursday, weather permitting, I’ll be flying over to North Carolina for ScienceOnline 2011, undoubtedly my conference highlight of the year. It’s a chance to catch up with some good and far-off friends and to meet some others for the first time. It will also be a busy trip. At last year’s conference, I chaired one session and this year, I appear to be inflicting myself on the other delegates no less than four times. Poor, poor people.
In the wet sands of Italy’s beaches, an epic battle of the sexes is playing out. The combatants are flatworms and though their bodies are simple, their sexual habits are anything but. Take the common species Macrostomum lignano. After sex, if a female has been filled with unwanted sperm from an undesirable partner, it can double over, put its mouth over its genital opening, and suck the sperm back out. It’s an easy fix that gives the female control over who fertilises her eggs.
But the sperm can put up a fight. It has a very different shape to the tadpole-like figure of human sperm. At its front, it has a sinuous ‘feeler’ that is uses to anchor itself into the walls of the female genitals. Further down, two large backwards-pointing bristles also help to hold the sperm in place. These barbed sperm can’t be sucked out easily. Even after the worm tries, you can often see several sperm sticking out of the genital opening.
There is another twist to this tale. For this flatworm, every individual is both male and female – they are hermaphrodites. When two of them mate, their male organs (the stylets) penetrate each other’s female organs (the antrums) at the same time. They form a little sexual ring, often spinning as they mate. Watch them go at it here.
