By Hamish Johnston at the Lindau Nobel Laureate Meeting in Germany
I arrived in the German town of Lindau yesterday evening expecting it to be a sleepy little burg where I would struggle to find somewhere open to get a bite to eat. Instead I was greeted at the station by a cacophony of car horns and singing as Germany had just beat Slovakia and claimed its place in the next round of the Euro 2016 football tournament.
I’m here in the far south of Germany for the 66th Nobel Laureate Meeting. Tomorrow I will be hosting a “press talk” about how immigration continues to shape the scientific world. Last week’s momentous decision by the UK to leave the European Union is sure to come up in the panel discussion, which will include input from two chemistry Nobel laureates – Martin Karplus and Daniel Shechtman. I will also be joined on the panel by two early-career physicists: Winifred Ayinpogbilla Atiah from Ghana and Ana Isabel Maldonado Cid from Spain.

First-up in this week’s Red Folder is a tale of killer asteroids, hubris and peer review from the Washington Post. The science writer Rachel Feltman has written a nice article about a claim by physicist-turned-entrepreneur Nathan Myhrvold that NASA’s research on asteroids that could potentially collide with Earth is deeply flawed. On Monday, Myhrvold posted a 111-page preprint on arXiv that argues that asteroid radii measured by NASA’s NEOWISE project are far less accurate than stated by NASA scientists. What’s more, Myhrvold seems to suggest that NEOWISE scientists have “copied” some results from previous asteroid studies.
Myhrvold began his career as a theoretical physicist and, after a stint as Microsoft’s chief technology officer, founded an intellectual-property firm. He has never worked in the field of asteroids, yet he has taken great exception to some of the physics and statistical analysis underlying the NEOWISE results. His paper has been submitted to the journal Icarus, but has not yet passed peer review – unlike the NEOWISE results. In her article, Feltman ponders why Myhrvold is actively promoting his controversial work – he was featured in a New York Times article on Monday – before it has passed peer review. She also speaks to several NEOWISE scientists, who are not amused.

“A year here is a really really long time,” says astronaut Scott Kelly in an interview (watch the video above) that he did on board the International Space Station (ISS) just a month before he returned to Earth in March this year. The retired astronaut is talking about the very real effects of spending a long period in space, specifically citing both the physical effects as well as the “psychological stress” involved. “During my time in orbit, I lost bone mass, my muscles atrophied and my blood redistributed itself in my body, which strained my heart. Every day I was exposed to 10 times the radiation of a person on Earth, which will increase my risk of developing a fatal cancer for the rest of my life. Not to mention the psychological stress, which is harder to quantify and is perhaps as damaging,” he says.
The comments were part of the announcement of his upcoming memoir, Endurance: My Year in Space and Our Journey to Mars, which will be published later this year. Despite the damming tone, Kelly is still a staunch supporter of manned spaceflight and missions such as those to Mars, he just has a much clearer view on the realities involved. Read more about his announcement over at the GeekWire website.

I’ve been thinking a lot recently about the make-up of the physics community, particularly as this month saw Physics World publish a special issue, “Physics for all: building a more inclusive discipline”, that examined ways to make physics as welcoming as possible for everyone. It looked, for example, at “microaggressions” in physics, the role of unconscious bias and whether physics is just for people from better socioeconomic backgrounds.
One article that attracted particular attention – based on informal feedback and e-mails I’ve received since the issue came out – was “Where people and particles collide”. Written by my Physics World colleague Louise Mayor, it looks at what life’s like for gender and sexual minorities at the CERN particle-physics lab in Geneva and the challenges people there faced in setting up an official LGBT Cern Club. (There is still no such club, but CERN has set up an LGBT “informal network”.)
The issues facing gender and sexual minorities have also been a theme here at the APS March meeting, with the launch this morning of a new APS report “LGBT Climate in Physics”. The report is based on focus groups, a “climate survey” of more than 320 members of the US LGBT physics community, and follow-up interviews with five survey participants. A further 2596 members of the entire APS community replied to a separate survey, of whom 2.5% identified themselves as LGBT.

You may think that a simple occurrence such as a tree shedding its leaves or an everyday activity such as knitting or ribbon-curling does not involve a great deal of physics, but you would be wrong. In a press session here at the APS March meeting entitled “The physics of everyday life”, three different groups of researches talked about the unexpectedly complex physical principles that govern all of the above mentioned instances.
Sunny Jung of the Bio-Inspired Fluid Lab at Virginia Tech in the US studies the shapes of different leaves and the thickness of their “petioles” or stalks – both of which determine the stresses a leaf can withstand on a windy day and what happens when it ultimately falls. Jung’s team studies this because leaves are actually very good at withstanding all kinds of stress and strain without buckling – something that could be applied to large man-made industrial objects such as suspended road-signs.
The researchers found that slender leaves are more likely to bend under high winds, whereas a flat leaf is more likely to twist at the stem before falling. They also discovered that the length of the stalk is determined by the size of the leaf, with larger leaves needing longer stems so that sunlight can cover more of their surface area.

So here we are in Baltimore to attend the 2016 March meeting of the American Physical Society (APS). We’re writing this at the window seats in a burrito bar on Pratt Street while staring at the hulk that is the Baltimore Convention Center, where nigh-on 10,000 physicists will be congregating all week.
We’ve been playing a game of “spot the APS attendee” while tucking into our burritos. Without wishing to stereotype physicists (okay, go on then, we will) they’re the ones with the backpacks stuffed with poster tubes, pulling little trolley suitcases, looking lost before veering towards the convention centre.
There are also some physicists inside Chipotle Mexican Grill – you can tell because they’re huddled around laptops looking at PowerPoint presentations showing graphs of Fermi surfaces and topological insultators. Probably not the usual subject of discussion in here.

Its been a strange week for scientists and celebrities popping up together on the world stage – what with rapper B.o.B and Neil deGrasse Tyson’s very public face-off about the former’s conspiracy theory claims of the Earth being flat – but it didn’t end there. In a celebrity trio that is even more surprising, physicist Stephen Hawking has come together with Hollywood actor Paul Rudd, (most recently starring in the film Ant-Man) in a video narrated by Keanu Reeves. Earlier this week, Caltech’s Institute for Quantum Information and Matter hosted the event One Entangled Evening: a Celebration of Richard Feynman’s Legacy. As a promo of sorts for the event – which had special appearances by Rudd, Reeves, Hawking, Bill Gates and even Yuri Milner, apart from actual quantum physicists such as John Preskill and Dave Wineland – they filmed the above video with Rudd and Hawking battling each other at a game of quantum chess. You will have to watch the video to see who wins.

Sparks of inspiration come from many sources, but for some of the 20th century’s most well known scientists, their four-legged pets played a key role. From Tesla’s cat “Macak” – his interest in electricity was lit as a child when he noticed sparks generated while he stroked Macak – to Schrödinger’s (real live) dog “Burshie”, these intellectual giants sought the company of pets just as we do and over at the Perimeter Institute’s website, you can learn all about “Great physicists and the pets who inspired them”. My favourite “pet” is of course Tycho Brahe’s infamous elk (you can read about it in the image above). With all of these pets about, its a miracle that a paper wasn’t eaten by a naughty dog or cat!

So much has been said about Einstein and his general theory of relativity (GR) that one would assume there isn’t two entire days worth of talks and lectures that could shed new light on both the man and his work. But that is precisely what happened last weekend at Queen Mary University London’s “Einstein’s Legacy: Celebrating 100 years of General Relativity” conference, where a mix of scientists, writers and journalists talked about everything from the “physiology of GR” to light cones and black holes, to M-theory and even GR’s “sociological spin-offs”.
The opening talk, “Not so sudden genius”, was given by journalist and author of “Einstein: A hundred years of relativity“, Andrew Robinson. The talk was very fascinating and early on Robinson outlined that Einstein stood on the shoulders of many scientists and not just “giants” such as Newton and Mach. But he also acknowledged that the scientist was always a bit of a loner and he preferred it this way. Robinson rightly pointed out that until 1907, Einstein was “working in brilliant obscurity” and later, even once fame found him, rootlessness really suited Einstein’s personality – he described himself as “a vagabond and a wanderer”.

Last month, China’s president Xi Jinping’s was on a state visit in the UK and while here, he toured a few academic institutions, including the UK’s new National Graphene Institute (NGI) in Manchester and Imperial College London. As we reported in an earlier blog, Nobel-prize-winning Manchester physicist Kostya Novoselov presented President Xi “with a gift of traditional Chinese-style artwork, which Kostya himself had painted using graphene paint”. This week we found out that the Imperial scientists also presented him with a “tiny gift” in the form of a 50 µm scale version of a section of the Great Wall of China, imaged above, created with a Nanoscribe 3D printer. Prince Andrew, who was also on the visit, was given an image of a panda leaping over a bamboo cane, which was printed on the tip of a needle.
