A brain sensor made of hydrogel is small enough to inject with a needle Hanchuan Tang and Jianfeng Zang A tiny sensor can be injected through the skull with a needle to help monitor brain health before dissolving within weeks. These sensors have been tested in animals, and could one day enable minimally invasive human implants to monitor traumatic brain injuries or neurological conditions such as
Molecular model of messenger RNA (pink) complexed with an RNA binding protein (light blue) LAGUNA DESIGN/SCIENCE PHOTO LIBRARY A cancer treatment that uses messenger RNA to launch an immune attack on cancer cells can completely shrink tumours in mice and is now being tested in people. Messenger RNAs – or mRNAs – are molecules that instruct cells to make proteins. They have risen to fame with the r

Anxiety disorders have been linked to depression and increased substance abuse, particularly of alcohol. A recent study found that men who have anxiety disorders are twice as likely to die from cancer as men who d
Michael Atiyah claims to have found a proof of the Riemann hypothesis James Glossop/The Times/News Syndication One of the most important unsolved problems in mathematics may have been solved, retired mathematician Michael Atiyah is set to claim on Monday. In a talk at the Heidelberg Laureate Forum in Germany, Atiyah will present what he refers to as a “simple proof” of the Riemann hypothesis, a pr
Electric busses were poised to take the world by storm 100 years ago, if only their fate hadn’t been sealed by a bunch of crooks. Green vehicles are finally making a comeback, but there were plenty of other modes of transport that became buried in the annals of history. The first subway in the US was the brainchild of inventor and publisher Alfred Beach, and it was literally a blast. Tunnelling fo
Zombie beetles Dr. Don Steinkraus/Professor of Entomology/University of Arkansas Species: Goldenrod soldier beetles (Chauliognathus pensylvanicus) Habitat: Meadows and fields in North America Dying on a bed of flowers might seem like a good way to go. Except it’s not when you’re a beetle suffering a gruesome fungal infection. Goldenrod soldier beetles (Chauliognathus pensylvanicus) feed and mate o
The controversial technique, which allows parents with rare genetic mutations to have healthy babies, has only been legally approved in the UK. But the birth of the child, whose Jordanian parents were treated by a US-based team in Mexico, should fast-forward progress around the world, say embryologists. The boy’s mother carries genes for Leigh syndrome, a fatal disorder that affects the developing
Sorry, you can no longer patent 3D-printed soap to kill the pests on your strawberries Ivan Mikhaylov/Alamy Stock Photo Alex Reben came up with 2.5 million ideas in just three days. Nearly all of them are terrible – but he doesn’t mind. He thinks he has found a way to thwart patent trolls by putting their speculative ideas in the public domain before they can make a claim. In his project, called A
Job opportunities for pigeons have been few and far between since electronic communication made their skills as messengers obsolete. But now it seems they could be put to work analysing medical images. So says the team who trained pigeons to distinguish between healthy and cancerous breast tissue. Richard Levenson at the University of California, Davis, and his colleagues showed pigeons microscope
This article relates to our “How much of a caveman are you?” quiz, which is currently offline Where does the information in the quiz come from? From this study: Nature, DOI: 10.1038/nature14317. It’s part of an on-going attempt to understand how prehistoric Europe was populated. To do this, geneticists start by pulling bits of DNA out of bones from archaeological sites across the continent. The si
Astrocyte nerve cells make a wealth of connections (Image: Riccardi Cassiani Ingoni/SPL) What would Stuart Little make of it? Mice have been created whose brains are half human. As a result, the animals are smarter than their siblings. The idea is not to mimic fiction, but to advance our understanding of human brain diseases by studying them in whole mouse brains rather than in dishes. The altered
It was named the language gene before we really understood what it did. Now mice given the human version of the FOXP2 gene are shedding light on how speech evolved in early humans. Mice with the gene seem to be better at learning to do a task automatically or unconsciously – something we do when we learn a new route to work, for example. The researchers claim that this, in conjunction with other w
