Forget invisibility cloaks. Researchers at Imperial College London have demonstrated – on paper, anyhow – a metamaterial “space-time cloak” that can conceal entire events from view, making a viewer see one thing while something entirely different takes place behind the cloak. Paging DARPA.
Raul Rabadan hunts deadly viruses, but he has no need for biohazard suits. His work does not bring him to far-flung jungles. He's neither medical doctor nor epidemiologist. He's a theoretical physicist with expertise in string theory and black holes, and he cracks microbial mysteries in much the same way he once tried to decode the secrets of the universe: He follows the numbers.
Future stitches could be made out of your own muscle cells, ensuring proper re-growth of injured muscle tissues.
Researchers in Massachusetts are implanting injured mice with microthreads coated with human muscle cells, reports Technology Review. The threads are made of the same proteins the human body uses to heal wounds, and when seeded with muscle cells, they act as a scaffold for the construction of healthy tissue.
Sterilization is hands down one of the most important technologies ever developed by mankind, but though we've known how to do battle with bacterial pathogens in places like the operating room for decades, superbugs like MRSA and Clostridium difficile persist in hospital environments, often causing serious medical complications.
Scientists just can't leave animals well enough alone. In some cases, it's for our benefit, whether we want to create new medicine, create better drug-sniffing dogs, or just breed giant delicious salmon. But sometimes it's for the animals themselves, shown with groundbreaking prostheses or embedded GPS to protect endangered animals from poachers. Check out our gallery of twelve of the craziest ways scientists are messing with animals.
Subjects are screaming in Katherine Kuchenbecker’s lab; they feel as if they’ve been shot. Kuchenbecker is testing a vest that she and her students designed to make videogames and military training more immersive. To simulate a bullet impact, the vest launches an actuator-controlled plunger called a solenoid into the unlucky gamer’s skin where a bullet would have penetrated. “People jump out of their chairs,” she says. “Crossing that barrier from the screen to your body makes the experience so much more real.”
Our resident artist Baarbarian has provided us with yet another vision of This Week in the Future. This week's roundup includes five stories from the last five Popular Science days, starring one doleful sailorbot.
Astronomers using the Hubble Space Telescope have made one of the most detailed dark matter maps ever, taking advantage of the dark matter’s own gravitational effects to bring it into the light.
The map suggests massive galaxy clusters may have formed earlier than expected, before dark energy stunted their growth, according to the Space Telescope Science Institute.
Huge cost overruns caused by mismanagement of the James Webb Space Telescope are delaying NASA’s keystone science project yet again, and could wreak havoc on the agency’s remaining astrophysics budget, a congressional panel found this week.
An Oxford-based research firm has announced the results of a release of genetically modified male mosquitoes in the Cayman Islands, the first experiment with GM mosquitoes to take place in the wild.
From May to October of this year, Oxitec released male mosquitoes three times a week in a 40-acre area. The mosquitoes had been genetically modified to be sterile, so that when they mated with the indigenous female mosquitoes there would be no offspring, and the population would shrink.
