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

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.

We are ill-prepared for climate-change risks

By Hamish Johnston

Today, the Intergovernmental Panel on Climate Change released its Working Group II (WGII) report entitled “Climate Change 2014: Impacts, Adaptation, and Vulnerability“. Over on our sister website environmentalresearchweb.org, editor Liz Kalaugher has written a news-analysis piece about the report that looks at the major risks facing different regions of the globe; who is most vulnerable to change; and why we must build on early efforts to adapt to climate change.

Kalaugher’s piece includes commentary from leading IPCC members, including Vicente Barros, co-chair of working group II. “In many cases, we are not prepared for the climate-related risks that we already face. Investments in better preparation can pay dividends both for the present and for the future,” says Barros.

Chris Field, WGII co-chair, adds “We definitely face challenges, but understanding those challenges and tackling them creatively can make climate-change adaptation an important way to help build a more vibrant world in the near-term and beyond.”

However, the report also warns that adaptation will be very difficult with high levels of warming. In that case, Field says that “even serious, sustained investments in adaptation will face limits”.

By Tushna Commissariat at the APS March Meeting in Denver

With the amazing variety of interesting talks at the APS meeting yesterday, I couldn’t possibly write up each and every one – I’d have to take today off, and there’s yet more physics to be learned today! In light of that, below is a short round-up of some of yesterday’s speakers and their work.

‘Mile-high’ physics

The Colorado Convention Centre where the APS is being held.

By Tushna Commissariat at the APS March Meeting in Denver

The city of Denver, Colorado has been invaded…or so I am sure the locals will feel over the next few days, as more than 9000 physicists from all over the world have arrived to take part in the APS March Meeting. I have been here in the “Mile-high city” of Denver – so nicknamed thanks to its official elevation that is exactly one mile or 5280 feet above sea level – since Sunday morning, and physics is the talk of the town as everyone descends upon the Colorado Convention Center (pictured above).

As always, there is a wide variety of interesting talks, sessions and press conferences over the next few days and I would have to clone myself multiple times to get around to all of them. Talking about cloning, though – I have just been to my first session, where Stanford researcher Patrick Hayden was taking about quantum information and asking whether or not it could be cloned in space–time. I will be speaking with Hayden later in the day, so watch this space if you would like to know more.

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.

Are ‘sterile neutrinos’ dark-matter particles after all?

Could sterile neutrinos constitute dark matter? (Courtesy: Bubul et al./ arXiv:1402.2301)

 

By Tushna Commissariat

It is always interesting to us at Physics World when a particular topic suddenly attracts the attentions of the physics community, especially when it’s a rather hotly debated subject. The past couple of days, for example, have seen a lot of talk about “sterile neutrinos”, based on two papers – published in quick succession on the arXiv preprint server – that suggest the tentative detection of these hypothetical paricles.

Both papers are based on an unidentified emission line seen in the X-ray spectrum of some galaxy clusters obtained by the European Space Agency’s XMM-Newton observatory. Intriguingly, sterile neutrinos are also considered to be possible dark-matter candidates, meaning that – if discovered – they would be the first fundamental particles to lie beyond the bounds of the Standard Model of particle physics.

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.

Celebrating Louis Essen and the birth of atomic time

By Hamish Johnston

On Friday I braved the torrential rains that have been soaking southern England to make the journey from Bristol to Teddington, which is the birthplace of the atomic clock. Situated in the leafy suburbs west of London on the swollen banks of the River Thames, Teddington is the home of the National Physical Laboratory (NPL), which is the UK’s standards and metrology lab.

Spacecraft duets, suprise supernovae, the dark side of physics and more

By Tushna Commissariat

While you would not actually be able to hear the uplifting notes of the music in the vast emptiness of space, a newly composed string and piano orchestral piece has unexpected ties to the cosmos. That’s because it is based on 36 years’ worth of data from NASA’s Voyager 1 and 2 spacecraft. Domenico Vicinanza, a trained musician with a PhD in physics who works at GÉANT, a European data-network company, says that he “wanted to compose a musical piece celebrating Voyager 1 and 2 together, so I used the same measurements (proton counts from the cosmic-ray detector over the last 37 years) from both spacecrafts, at the exactly same point in time, but at several billions of kilometres of distance [of] one from the other”. The result of this “data sonification” is a rather beautiful piece of music – one of the best examples of physics and the arts coming together that we have heard. Of course, the story garnered considerable interest…you can read more about on the Wired and Guardian websites.
