Bad Boy of Science” Sam Gregson and colleagues are organizing an evening of physics-related comedy at CERN in Geneva on Friday 13 June. “LHComedy: No Cause for ConCERN” will kick off in the CERN Globe at 19:30 and is billed as “a fantastic and innovative new way of presenting the work going on at CERN and engaging with the public”. The line-up from CERN includes Canadian PhD student Nazim “License to Thrill” Hussain, quantum diarist Aidan “The Mole” Randle-Conde and Cat “Schrödinger” Demetriades. You can watch last year’s comedy extravaganza from CERN here. Others involved in the project are Clara Nellis, Alex Brown, Hugo Day, Claire Lee and Rob Knoops.

A day in the life of an astronaut, Hawking’s football conclusions, politics and science and more

For most of us, the life of an astronaut is one of excitement and adventure. Indeed, the mere thought of being a “real live astronaut” brings out the gleeful inner child in many, and photographer Tim Dodd is much the same. After purchasing a Russian high-altitude space suit from an online auction website, Dodd put together a series of photographs titled “A day in the life of Everyday Astronaut”, my favourite of which you can see above. Do take a look at the rest of the excellent series on Dodd’s website and follow him on Instagram for even more of the same.

A new Longitude Prize, global cooling in the 1970s, inspirational creatures and more

A bird of prey swoops out of the sky, grabs its victim from the ground and flies off into the distance. It’s what a bird does instinctively, but how could we get a drone aircraft to do the same thing? That’s the subject of one of the papers in a special issue of the journal Bioinspiration & Biomimetics that focuses on “Bioinspired flight control”.

The above sequence of images is from a paper entitled “Toward autonomous avian-inspired grasping for micro aerial vehicles” by Vijay Kumar and colleagues at the University of Pennsylvania. The special issue also includes work on aircraft inspired by flying snakes, flocking birds and incredibly stable moths.

Microwave pockets, space station strife and dreaming of Mars

By Hamish Johnston

The physics of how the contents of a microwaved pastry can become “hotter than the Sun” is the subject of an entertaining and informative blog entry by Ethan Siegel. He looks at the physics of heating “microwave pockets”, those roof-of-your-mouth-scalding savoury treats that appeared on shelves in the 1980s. He explains why the outer portion of a pocket can be extremely hot, while the interior remains frozen – and why pockets often explode when heated through.

Siegel’s been a bit cheeky and republished this entry from 2009, but I suppose it’s timeless and I’m sure you can still buy microwave pockets somewhere! His blog is called Starts With a Bang and the entry is entitled “Throwback Thursday: The physics of hot pockets”.

As the crisis in the Ukraine drags on, scientists are beginning to worry about the effect it could have on scientific collaborations involving Russia and the West. Several websites are reporting that Russia is threatening to ban US astronauts from the shuttles that travel to the International Space Station (ISS). Indeed, the Independent quotes Russia’s deputy prime minister Dmitry Rogozin as saying that it would be possible for Russia to independently operate its portion of the ISS, while the US would not be able to do so. Indeed both toilets on the ISS are Russian, so it could get very messy up there!

The biophysics of Godzilla, skipping stones, Schrödinger in the morning and more

 

By Hamish Johnston

I’m a bit of a connoisseur of the art of stone skipping. That’s because I grew up a stone’s throw from the western end of Lake Ontario, which thanks to its shale shoreline has the best skipping stones in the world. As a result, I was fascinated to read a piece on the Figure One blog about entitled “Frisbee meets fluid: Skipping stones takes spin and skill”.

Winning rock-paper-scissors, meeting a future Nobel laureate, hot new batteries and more

By Hamish Johnston

When I was a PhD student, there was a group of retired professors that shared a tiny office in the physics department. It was whispered that one of them was extremely wealthy thanks to a successful commercial spin-out and we marvelled at the fact that he came in to work every day rather than enjoying the fruits of his labours. However, it wasn’t the wealthy professor who was destined for international fame. In 1994 his officemate Bertram Brockhouse shared the Nobel Prize for Physics, and Brockhouse’s quiet life changed dramatically. Indeed, he got his own office!

I was reminded of this little group when I read ZapperZ’s blog entry about his encounter with Ray Davis before Davis bagged the 2002 Nobel for his work on neutrinos. Sitting next to Davis on a two-hour flight, ZapperZ had an inkling that he was beside an interesting character after their brief chat about physics. But it wasn’t until the Nobel was announced several years later that he realized the opportunity he had missed.

Earth’s cousin, alien intelligence, Galileo’s game and more

Early last week, astronomers announced that they had found the first Earth-sized exoplanet that is comfortably within the habitable zone of its parent star, using NASA’s Kepler telescope. The new planet, dubbed Kepler-186f, is a close cousin of the Earth as it has a radius that is only 10% larger than that of the Earth, meaning that it could have liquid water on its surface, allowing for the tantalizing possibility of some form of life to exist upon it. At last count, Kepler has now discovered and confirmed 1706 exoplanets.

So it was rather interesting to come across two stories that looked at the implications of life beyond our planetary neighbourhood. Paul Gilster, who writes the Centauri Dreams blog had a rather interesting post on how artists and illustrators need to work with scientists to depict each new exoplanet, to make the images look visually stunning, while still being scientifically accurate. Gilster also talks specifically about the image (see above) that illustrates the newly found Kepler-186f.

3D printing food, ‘Top 10′ lists, teenage nuclear physicists and more

 

By Tushna Commissariat

Over the past few years, 3D printing has captured the imagination and interest of scientists and the public alike. Now, a €3 million EU-funded project known as “PERFORMANCE – PERsonalised FOod using Rapid MAnufacturing for the Nutrition of elderly ConsumErs” is adapting 3D printing technology to food in order to create easily digestible sustenance that is not only nutritious but also looks and tastes like the real thing. The proposed printer would work like its conventional inkjet counterpart – except the cartridges would be filled with liquefied food instead of ink! While that may not sound like the most appetising way of eating your five-a-day, it might come as a relief for those who suffer from a condition known as “dysphagia” that makes swallowing food difficult. You can read more about the proposed scheme on the EU’s Horizon magazine website and take a look at the video above.

Why electricity grids fail, what to do if your PhD is stolen, and what is a ‘Suris tetron’?

 

By Hamish Johnston

It’s the nightmare scenario for any PhD student: losing all those research results that you carefully squirreled away for when you finally sit down to write your thesis. That’s just what happened to biologist Billy Hinchen, who lost four years’ worth of 3D time-lapse videos of developing crustacean embryos when his laptop and back-up drives were stolen. Find out what happened next in “What would happen if you lost all of your research data?” by Julia Giddings at the scientific software firm Digital Science. Hinchen also tells his tale of woe in the video above.

Cakes that are out of this world, what’s on Andre Geim’s iPod and who’s the April fool?

The joke’s on me: click on the image for a larger version where you can see the instruction for users

The joke’s on me: click on the image for a larger version where you can see the instruction for users

By Hamish Johnston

On Tuesday I was feeling particularly pleased with myself over the April Fool’s piece that I penned. It was about a fictitious microwave-oven ban organized by radio astronomers at the UK’s Jodrell Bank Observatory. But now it looks like I might have a bit of microwaved egg on my face because two of my colleagues visited Jodrell Bank this week and guess what? Astronomers there have built a Faraday cage around the microwave in their tearoom to stop it from interfering with their equipment. Louise Mayor took the above photos: click on the image to read the reminder to microwave users.
