By Hamish Johnston

Who hasn’t wanted to float high above the Earth and gaze down on our planet as sunlight and clouds dapple across its surface. Thanks to the “Glittering Blue” animation, such views are not just for a privileged few astronauts. This stunning animation of one day’s observations from the Japanese weather satellite Himawari-8 has been put together by satellite-imagery analyst Charlie Lloyd. He has also included a nice FAQ page that explains some of the amazing phenomena captured by the satellite, including a huge tropical storm and the daily cloud cycles of a rainforest.

You can read more about Lloyd and the images in The Atlantic article “A New and Stunning Way to See the Whole Earth”. If you want to know what Himawari-8 is seeing right now, it has its own live webcam.

What it’s like collaborating with physicists in China

 

By Matin Durrani

Barry Sanders – director of the Institute for Quantum Science and Technology at the University of Calgary, Canada – last week visited the headquarters of IOP Publishing, which publishes Physics World.

Sanders has just taken over from Eberhard Bodenschatz as editor-in-chief of New Journal of Physics, and it’s a coup to have him in the role, not least because he’s an incredibly busy physicist, making – by his reckoning – at least 150 international flights a year.

The February 2016 issue of Physics World is now out

 

By Matin Durrani

Welcome to the February 2016 issue of Physics World magazine.

As I explain in the video above, this month we have a package of articles looking at some of the issues surrounding peer review, including a news-analysis piece by Physics World news editor Michael Banks, who talks to a range of figures in physics and publishing with views on this subject.

Our cover feature this month is on the new interdisciplinary science of “network physiology”. Elsewhere in the issue, John Campbell from the University of Canterbury in New Zealand looks at Rutherford’s secret work in the First World War using sonar to spot submarines, while science writer Matthew Francis looks at efforts to rewrite the rules of gravity.

Scientists battle celebrities, a quantum ‘unconference’ and space travel, past and future

 

By Tushna Commissariat

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.

More data needed on the STEM ‘shortage’

By Margaret Harris

“Science has always been the Cinderella amongst the subjects taught in schools…not for the first time our educational conscience has been stung by the thought that we are as a nation neglecting science.”

Sounds like something David Cameron or Barack Obama might have said last week, right? Wrong. In fact, it comes from a report by the grandly named Committee to Enquire into the Position of Natural Sciences in the Educational System of Great Britain, which presented its findings clear back in…1918.

I came across this quotation thanks to Emma Smith and Patrick White, a pair of education researchers at the University of Leicester who have spent the past few years studying the long-term career paths of people with degrees in science, technology, engineering and mathematics (STEM). Smith and White presented the preliminary findings of their study at a seminar in Leicester yesterday, and one of the themes of their presentation – reflected in the above quote – was the longevity of concerns about a shortage of STEM-trained people, especially university graduates. As Smith pointed out, worries about the number and quality of STEM graduates are not new and, historically, reports of a “STEM crisis” have been as much about politics as they have economic supply and demand.

Scientists officially ground Spider-Man

By Tushna Commissariat

Don’t tell the kids just yet, but becoming Spider-Man, even after being bitten by a radioactive spider, is looking less and less likely for us humans – we are just too big. The latest work, done by researchers at the University of Cambridge in the UK, has shown that gecko-sized is pretty much the largest you can be if you realistically want to scale up walls with adhesive pads. Any bigger, and most of your surface area would need to be covered in large sticky pads to pull off the gravity-defying walk. Indeed, the team estimates that roughly 40% of an average human being’s total body surface would need to be sticky – this means a whopping 80% of your front would be covered in adhesive pads.

Physicists’ pets, seven stars for Bowie, ping-pong in space and more

By Tushna Commissariat

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!

Is the solar system’s planetary count back up to nine?

 

By Tushna Commissariat

In August 2006 the distant world that is Pluto was “downgraded” from planet to “dwarf planet” by the International Astronomical Union. Now, 10 years on, it seems that a new planet may be joining the ranks of the other more familiar eight, thanks to two researchers from the California Institute of Technology in the US, who have uncovered evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system.

Although it has not been observed directly just yet, Konstantin Batygin and Mike Brown discovered the planet’s existence via mathematical modelling and computer simulations. The newly found “Planet 9” is about 10 times as massive as Earth and its orbit is nearly 20 times farther from the Sun on average than Neptune, placing it firmly within the Kuiper belt. If the duo’s calculations are correct, it means that it takes Planet 9 anywhere between 10,000 and 20,000 years to complete one orbit, making it a long year indeed. The research is presented in The Astronomical Journal (which is published by IOP Publishing, which also publishes Physics World).

Female astronomers through the ages, science-inspired phone cases and the return of the incandescent light bulb

Portraits of 21 leading female astronomers

The first documented female astronomer in Britain was Margaret Flamsteed (1670–1739), who worked with her husband John at the Royal Observatory in Greenwich. That’s according to astronomer Mandy Bailey of the UK’s Royal Astronomical Society, who has written an article entitled “Women and the RAS: 100 years of Fellowship”. As the title suggests, this year is the centenary of the first women becoming fellows of the RAS.

To celebrate the centenary, the RAS commissioned Maria Platt-Evans to photograph 21 leading female fellows. The portraits appear above and are also presented in the slide show “Women of the Royal Astronomical Society”, which includes short biographies.

Has Advanced LIGO found gravitational waves?

Rumours of a discovery at Advanced LIGO have resurfaced. (Courtesy: LIGO)

By Hamish Johnston

For the past few days, rumours have been swirling that the Advanced Laser Interferometer Gravitational-wave Observatory (Advanced LIGO) has detected gravitiational waves. Advanced LIGO comprises two huge (kilometre-sized) interferometers in the US, which began taking data in September 2015. The source of the rumours seems to be the physicist and author Lawrence Krauss, who wrote on Twitter yesterday that “My earlier rumour about LIGO has been confirmed by independent sources. Stay tuned! Gravitational waves may have been discovered!! Exciting.”

And it would be very exciting, except for the fact that LIGO spokesperson Gabriela González of Louisiana State University has since told the Guardian newspaper that “The LIGO instruments are still taking data today, and it takes us time to analyse, interpret and review results, so we don’t have any results to share yet.”
