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, an €3 million EU funded project known “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 may 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.

In praise of rocket scientists, ironworkers, superheroes and more

Dark Matter and Big Data are just two of the superheroes inspired by physics.

Q: What do you call physicists studying the electrical properties of salad greens?
A: Rocket scientists!

But that’s old news, so lettuce move on to this week’s highlights from the Red Folder…

The rocket scientists referred to in the headline are econophysicists, who got a bad rap from Warren Buffet and others during the financial crisis of 2008. Now that the great depression is nearly over, physicist and author Mark Buchanan has a much more upbeat assessment of those who have made the transition from physics to economics in his blog entry “What’s the use of ‘econo-physics’?”.

BICEP2 surprise visit, a bizarre rant, credible science fiction and more

 

By Hamish Johnston

The big story this week is that astronomers working on the BICEP2 telescope may have spotted the first direct evidence for cosmic inflation.  This is very good news for the physicist Andrei Linde, who along with Alan Guth and others did much of the early work on inflation. In the above YouTube video Linde, who is certainly in the running for a Nobel prize, receives a surprise visit from BICEP2 team member Chao-Lin Kuo. Kuo is the first to tell Linde and his wife, the physicist Renata Kallosh, the news that the theory that Linde developed more than 30 years earlier had finally been backed up by direct observational evidence. Not surprisingly, champagne glasses are clinking!

Here at physicsworld.com we have tried to tell both sides of the story: the thrill of seeing the first hints of cosmic inflation, tempered with calls for caution that more data are needed before inflation is victorious over other theories describing the early universe.

Web bill-of-rights, cosmic popular culture, origami microscopes and more

 

By Tushna Commissariat

This week, the Web celebrated its silver anniversary. In March 1989 CERN scientist Tim Berners-Lee proposed a rather contemporary way of linking and sharing information and so the Web was born. There have been numerous stories on the subject this week, but most interesting of all was a Guardian article where Berners-Lee called for the development of an “online Magna Carta” – a bill of rights to enshrine and protect the independence of the Web. “We need a global constitution – a bill of rights,” he said. You can read more about the 25th anniversary at the “World Wide Web Consortium”.

Bananaman, fusion boy, an astronaut and more

By James Dacey

The Red Folder is bulging this week with some weird and wonderful physics stories from around the Web. Here is a round-up of some of the best we have stumbled across.

One of the more eye-catching articles this week included the surreal image of Stephen Hawking posing for a picture with a bunch of men all dressed as Bananaman. In case you’re not familiar with this brilliant character, Bananaman is a comedy super hero created in the 1980s by British cartoonists who valued the importance of nutrition. When Eric Wimp – an ordinary British schoolboy – eats a banana he turns into our hero, a fully grown man in a blue and yellow suit with special powers to rival both Batman and Superman. Anyway, I digress. According to the Telegraph, the 10 besuited chaps in question were on a stag do in Cambridge. They were lost (perhaps a few too many banana liqueurs?) when they turned a corner and spotted the world-famous cosmologist getting out of a car. The result was a group shot with far more a-peel than any of those self-indulgent Oscars selfies that have been doing the rounds this week. Please accept my apologies for that bad pun.

Homework help from NASA, rescue missions, top technologies and more

By Tushna Commissariat

Who doesn’t like a bit of help with their homework – not 4-year-old Lucas Whiteley from West Yorkshire in the UK.  When faced with some tough and rather complex scientific questions, the enterprising child filmed a video of himself asking the US space agency NASA for some help. And much to his delight, he got a video response courtesy of NASA engineer Ted Garbeff of the Ames Research Center in California. In the 10-minute video, Garbeff answers Whiteley’s questions including “How many stars are there?” and “Did any animals go to the Moon?” Of course, the story garnered nation-wide interest and was covered by the Huffington Post, the Telegraph and others. Take a look at Garbeff’s response video above.

Golden-anniversary physics, flaming challenges, smart lists and more

How do you explain the science behind a rainbow to a child?

By Tushna Commissariat

It never rains but it pours, they say, and 1964  experienced quite a downpour of amazing “physics firsts” as the first papers about quarks, the Higgs mechanism and the EPR paradox or Belle’s inequality were all published. Also, Arno Penzias and Robert Woodrow Wilson made their first measurement of the cosmic microwave background on 20 May 1964, detecting the whisper of the Big Bang. To celebrate 50 years since these world-changing discoveries were made, the Harvard-Smithsonian Centre for Astrophysics has produced a webcast (you can watch the video on their YouTube page in a week’s time) featuring leading cosmologists Alan Guth, Robert Woodrow Wilson, Robert Kirshner and Avi Loeb. You can read more about it in this fascinating article by David Kaiser on the Huffington Post website, as he take a deeper look at the eventful year of 1964.

Cruise-ship physics, the many ways to tie a tie, shaken-up carbon dating and more

By Tushna Commissariat

If you like piña coladas and quantum mechanics, then we hope you are currently on the two-week “Bright Horizons 19” Southeast Asia cruise, as on board is physicist and writer Sean Carroll. He will be giving multiple lectures over the next 15 days on everything from the Higgs boson to dark matter and other fundamentals of quantum mechanics. Also floating along with Carroll are other lecturers who will cover topics from natural history to genetics to military strategy. If, like us, you are stuck at home, you can take a look at Carroll’s slides on his blog, maybe have a cocktail while you are at it.
