It turns out to be fairly complicated to figure out how electricity will flow through materials – a crucial question for designing new electronics and semiconductor materials.
The green blob is metal-rich molten sulfide in an ore from the Norilsk area in Siberia, the most valuable accumulation of metals of any kind on the planet.
Liquid minerals containing sulfur behave like a hot knife through butter – they're so corrosive they can melt their way through solid rock.
Finger mounted flexible detector.
An X-ray sensitive ink means future detectors could be printable, portable and flexible.
Medical imaging such as MRI can seem daunting, and perhaps even a little sci-fi.
There are many different types of medical imaging and they all pick up different things.
Teeth and bones can tell something about age – but not someone’s birthday.
Journal of Forensic Dental Sciences
If an undocumented migrant is a minor or an adult can have far-reaching implications. A forensic anthropologist explains why relying solely on dental X-rays to determine age doesn't work.

New research uses pathology in dinosaur bones to look at predator-prey interactions in the fossil record.
The Small Magellanic Cloud galaxy here seen in infrared light, but it looks different when viewed at other wavelengths.
The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.
Marie Curie in one of her mobile X-ray units in October 1917.
During World War I, Marie Curie left her lab behind, inventing a mobile X-ray unit that could travel to the battlefront and training 150 women to operate these 'Little Curies.'
Studying mysterious neutron stars could uncover the secrets of exotic physics – and a way to navigate the stars.

Modern sabre-tooth mammals have their canines constantly on display. This allows them to seduce mates. But was sexual selection also an important phenomenon among our pre-mammalian ancestors?
The X-rays of the Australian Synchrotron reveal a remarkably clear picture of the woman’s face.
It took cutting edge technology and a collaboration between the Australian Synchrotron and the CSIRO to reveal the mysterious hidden lady in Degas's famous painting.
The computer does more of the work than you might think.

Pairing more powerful computers with increasingly sensitive scanners can yield many benefits in medicine and other fields.
The relentless pursuit of showy flowers for garden display – as seen at Chelsea Flower Show – has seen some odd uses of radiation and chemicals .
An artist’s impression of the ASTRO-H telescope.
The universe looks very different with X-ray vision, revealing some of the most energetic interactions in our galaxy. Japan's new Hitomi telescope will help us see these wonders.
The dispute between Philipp Lenard and Albert Einstein sheds considerable light on the power of nonscientific concerns to sway scientists.

Scientists are not always as scientific as many suppose. Recent well-publicized cases of scientific fraud prove that scientists can be as susceptible to the allures of wealth, power and fame as politicians…
While doctors still use their senses for diagnoses, they have technologies to back them up.
“Diabetic urine”, the surgeon Herbert Mayo wrote in 1832, “is almost always of a pale straw or greenish colour. Its smell is commonly faint and peculiar, sometimes resembling sweet whey or milk.” The use…
Not your standard protein.
For more than 100 years, scientists have “peered” at atoms in a crystal by analysing the way they scatter X-rays. This process, known as crystallography, reveals the chemical structure of compounds in…
