It’s not often that you come across a museum exhibit based on a Physics World article. But I did on Saturday at the Mind Museum – an extraordinarily beautiful and original science museum in Taguig, on the outskirts of Manila in the Philippines.
Not only that, the exhibit is right at the entrance. You may recall that I once asked Physics World readers for their thoughts on the 10 most beautiful experiments and wrote up the results in an article in September 2002. The project turned into a book, The Prism and the Pendulum: The Ten Most Beautiful Experiments in Science, which came out the following year and which Physics World reviewed.
Maria Isabel Garcia, who was planning exhibits for the then-future Mind Museum, saw the article and book, and created an exhibit based on it, consisting of videos and explanations of each of the 10 experiments, along with a sculpture designed by the Philippine artist Daniel de la Cruz.

High-temperature (high-Tc) superconductivity has given hope and heartbreak in equal measure to physicists since the phenomenon was first discovered in 1986.
The hope is two-fold: that we will soon understand why superconductivity arises in this complex group of materials; and that this knowledge will lead us to a material that is a superconductor at room temperature. The former would be a triumph of the physics of highly correlated systems and the latter would spark a technological revolution.

I am a condensed-matter physicist by training and sometimes I struggle to get excited by the latest breakthrough in particle physics – usually because most don’t seem much like breakthroughs to me. The latest hot paper from physicists working on the Large Hadron Collider (LHC) at CERN is a perfect example of what I am talking about.
Writing in Nature this week, physicists working on the CMS and LHCb experiments at CERN announced the discovery of a rare decay of the strange B-meson, as well as further information regarding an even rarer decay of the B0-meson. In both cases the decays produce two oppositely charged muons. An animation of how the strange B-meson decay is detected by the CMS appears in the video above.

Has D-Wave Systems built the world’s first commercial quantum computer? The Canada-based company says it has but some physicists in the quantum-information community beg to differ. Putting aside heady questions like “Does it work?”, I think everyone agrees that the Tardis-sized black boxes that house D-Wave’s processors look great. But what exactly is inside?

The telescope marked the 400th anniversary of Galileo’s first telescope, which he presented to policy-makers from the Venetian Republic on 25 August 1609.

“One well-lit place” is the best way to describe the exhibition hall at Javits Center in New York when it opened on Tuesday morning. I fully expected to be bedazzled at every turn because the venue is hosting LIGHTFAIR, the world’s largest lighting technology trade fair, and so the hall is packed with more than 600 booths designed to highlight, so to speak, the world’s lighting revolution.

A couple of years back, I had the pleasure of travelling 1100 metres below ground to visit a dark-matter laboratory at the bottom of the Boulby Mine on the north-east coast of England. The journey was certainly memorable – it involved plunging down in a rattling lift cage for several minutes with a group of miners setting off on their morning shift. Once in the lab – housed inside a souped-up set of trailers – I interviewed physicist Sean Paling about the experimental projects going on there.
Setting up an underground lab, like that at Boulby, certainly doesn’t come cheap and in recent years, many have started to diversify into new areas. In the May issue of Physics World, which is now out in print and digital formats, Paling and his colleague Stephen Sadler – who is director at DURRIDGE UK Radon Instrumentation – describe the renaissance in the science taking place far beneath our feet. Studies in underground labs now range from Mars rovers to muon tomography and from radioactive dating to astrobiology.

It’s been a great week for birds – or at least those flying over the state of New York – after state governor Andrew Cuomo pledged to create safer migration routes for our feathered friends. All state buildings will now have to comply with a national US initiative that seeks to curb levels of light pollution, which can disorient birds and lead to huge numbers of avian deaths by “fatal light attraction”.
Many species of bird rely on the light from star constellations to help them navigate during spring and autumn migrations. Unfortunately, artificial light sources can throw the animals off course, and light reflected from glass can cause the birds to smack into windows, walls, floodlights and other hard surfaces. It is estimated that as many as a billion birds succumb to this cruel end each year in the US alone, according to the US Department of Agriculture.

One of the big aims of the International Year of Light (IYL 2015) is to take scientific ideas out of the lab to show the world just how inspiring and useful they can be. In the process, it can forge relationships between different communities, including scientists, engineers, artists, journalists, architects, politicians, aid workers…the list goes on.
Here in Bristol, where Physics World is produced, we’ve seen a fantastic local example of this by way of an art project at the University of the West of England (UWE). Second-year graphic-design students were set the brief of creating posters themed on IYL 2015. Last night we hosted an evening at IOP Publishing headquarters to showcase the students’ work and to let them find out more about science publishing.

With a smartphone in every pocket and remotely operated cameras on every street corner, digital cameras are a ubiquitous part of life. Last year alone an estimated two billion cameras of various sorts were sold worldwide – with such sales likely to increase. While personal cameras are easily recharged, many new remote applications require smaller and longer-lasting power supplies.
But what if your camera could self-power while you take selfies? This is the idea put forward by Shree Nayar and his colleagues at Columbia University in New York City, who have created the first ever completely self-powered video camera.
