Semiconductor devices capable of responding with high precision to touch and finger movement are a step towards creating surgical gloves for use in medical procedures such as local ablations and ultrasound scans.
Researchers from the University of Illinois at Urbana-Champaign, Northwestern University and Dalian University of Technology used ultrathin, stretchable, silicon-based electronics and soft sensors mounted onto an artificial “skin” and fitted to fingertips.
The team hopes to incorporate the devices into a smart glove with the flexibility of skin that creates virtual sensations of everything from texture to temperature.
“Imagine the ability to sense the electrical properties of tissue, and then remove that tissue, precisely by local ablation, all via the fingertips using smart surgical gloves,” said co-author of the study Professor John Rogers.
Scientists Discover a New Species of Caecilian That Looks Like…
by Eddie Wrenn
The unique creature, an Caecilian ( a type of amphibian), Atretochoana eiselti, was found after engineers drained a hydroelectric dam which spans a river connected to the Amazon. Biologists discovered six of the unusual-looking creatures - each about a metre long - at the bottom of the river-bed on the Madeira river in Rondonia, in Brazil.
Biologist Julian Tupan, who works for Santo Antonio Energy - the company which constructed the dam - said: ‘Of the six we collected, one died, three were released back into the wild and another two were kept for studies.
Mr Tupan added: ‘We think the animal breathes through its skin, and probably feeds on small fish and worms, but there is still nothing proven. ‘The Amazon is a box of surprises when it comes to reptiles and amphibians. There are still much more to be discovered’

That’s not a photograph, that’s a painting of an old five-dollar bill. In fact, it is so close to life, it got the painter arrested! The artist, Irish-American painter William Harnett (1848-1892), was taken in for counterfeiting. The judge declared that “the development and exercise of a talent so capable of mischief should not be encouraged.”

Alexander Reid (1854-1928) was an influential Glasgow art dealer who was a flatmate of Van Gogh and his brother Theo at the time this work was painted.
