Medical imaging is a multidisciplinary science encompassing a wide range of powerful techniques with applications in both patient care and fundamental biological studies. In this latest Physics World focus issue, we examine how imaging technologies such as X-ray computed tomography (CT), magnetic resonance imaging and other nuclear, ultrasound and optical imaging techniques have evolved in recent years. We also take a look at what improvements can be expected in the future.

This year has been one of change for India. In May, some 800 million eligible voters went to the polls in an election that was won by the Bhartiya Janata Party. Led by Narendra Modi, the party went on to form a coalition government called the National Democratic Alliance.
Our Special Report, which you can read free online, kicks off by looking at how science is faring under Modi’s fledgling administration. Indeed, in September, Modi was personally on hand at the Indian Space Research Organisation (ISRO) to laud engineers who had just carefully manoeuvred the Mars Orbiter Mission into position around the red planet – a feat that announced India as a major player in space exploration.
Modi’s personal interest in ISRO will not only please the organization’s chairman K Radhakrishnan, who we interview for the report, but could also be seen as a sign that the new administration is serious about boosting science in the country.

The cover feature of the August issue of Physics World, which is now out in print and digital formats, looks at the Sun – and in particular, at the consequences here on Earth of a “solar super-storm”. As I point out in the video above, these violent events can disturb the Earth’s magnetic field – potentially inducing damaging electrical currents in power lines, knocking out satellites and disrupting telecommunications.
One particularly strong solar super-storm occured back in 1859 in what is known as the “Carrington event”, so named after the English astronomer who spotted a solar flare that accompanied it. The world in the mid-19th century was technologically a relatively unsophisticated place and the consequences were pretty benign. But should a storm of similiar strength occur today, the impact could be devastating to our way of life.

It’s time to tuck into the latest focus issue of Physics World, which explores some of the latest research into optics and lasers.
The focus issue, which can be read here free of charge, kicks off with a report from the Centre for Quantum Photonics at the University of Bristol in the UK, which is driving a new approach to quantum computing based on integrated photonic circuits.
Elsewhere in the issue, you can find out from Joel England, a physicist at Stanford University in the US, about the new photonic research that could see particle accelerators shrunk to the scale of microchips.
Meanwhile, the huge potential of the photonics sector in general is underlined in our keynote interview with the chief executive of Jenoptik, Michael Mertin, who is also president of the European Union’s Photonics21 consortium, which seeks to unify the European photonics community and advises the European Commission on photonics research, development and innovation needs.

With this year’s FIFA World Cup drawing ever closer, Physics World turns its attention to Brazil – the nation hosting the planet’s biggest sporting event.
We’re not, of course, looking at the country’s footballing prowess or examining the controversial – and staggering – sums being spent on staging the World Cup.
Instead, the latest Physics World Special Report examines the challenges and opportunities for physicists in Brazil – the fifth biggest nation by size and the world’s seventh-largest economy.
Physics in the country is thriving, with the Brazilian government having more than quadrupled the amount of money invested in research and development since the turn of the century.

If you’ve been keeping an eye on this blog, you’ll remember that I spent a week in Brazil last November gathering material for an upcoming Physics World Special Report, which will examine the challenges and opportunities facing physicists in the world’s fifth largest country. I travelled to São Paulo, São José dos Campos and Rio de Janeiro, visiting everywhere from the first overseas offshoot of the International Centre for Theoretical Physics to the Brazilian National Observatory, where Brazilian research pretty much began.
I’ve just been putting the finishing touches to that report, which includes news, features and an exclusive interview with the Brazilian science minister Marco Antonio Raupp, who is a physicist by training. Brazil’s investment in science has more than quadrupled over the last decade and in the interview Raupp outlines his priorities for the Brazilian research community. Stay tuned for the Physics World Special Report, which we’ll make available via this website from next month. (One rather flippant question we asked Raupp is who he thinks will win this year’s FIFA World Cup taking place across Brazil this summer – we didn’t have room to fit his answer into the report, but I can exclusively reveal on this blog that the Brazilian science minister has got his money on the home nation. Well, he would say that, wouldn’t he?)
