Image via Wikipedia Inspired by the social interactions of ants and slime molds, University of Pittsburgh engineers have designed artificial cells capable of self-organizing into independent groups that can communicate and cooperate. Recently reported in the Proceedings of the National Academy of Sciences (PNAS), the research is a significant step toward producing synthetic cells that

Users are said to have reported “high satisfaction” with the device If a woman wishes to avoid pregnancy for the time being, but thinks she might want to get pregnant at some point in the future, then using an intrauterine device (IUD) is often a good course of action – the simple devices are now the world’s most

A reimagining of today’s computer chips by UNSW engineers shows how a quantum computer can be manufactured – using mostly standard silicon technology. A reimagining of today’s computer chips by Australian and Dutch engineers shows how a quantum computer can be manufactured – using mostly standard silicon technology. Research teams all over the world are

Free speech advocates and Internet users are protesting new Indian regulations restricting Web content that, among other things, can be considered “disparaging,” “harassing,” “blasphemous” or “hateful.” The new rules, quietly issued by the country’s Department of Information Technology earlier this month and only now attracting attention, allow officials and private citizens to demand that Internet sites

The precise cellular signalling responsible for kidney regeneration and exposing the multi-layered nature of kidney growth has been pinpointed in a new study. The research paves the way for novel cellular and molecular therapeutics to achieve human kidney regeneration and alleviate the shortage of kidney organs for transplantation. Doctors and scientists have for years been

Salk team finds molecule that slows the clock on key aspects of aging in animals Salk Institute researchers have found that an experimental drug candidate aimed at combating Alzheimer’s disease has a host of unexpected anti-aging effects in animals. The Salk team expanded upon their previous development of a drug candidate, called J147, which takes

As an ecologist of ice age giants, I long ago came to terms with the fact that I will never look my study organisms in the eye. I will never observe black-bear-sized beavers through binoculars in their natural habitats, build experimental exclosures to test the effects of mastodons on plants, or even observe a giant

Skylon is expected to slash the cost of launching satellites into orbit more than 10 times. Critical tests have been completed on a revolutionary rocket engine that could send astronauts into orbit and accelerate aircraft to five times the speed of sound. The British company heading the Sabre project said it was ‘the biggest breakthrough

Our bodies are extremely efficient at storing fat from food into our fat tissue. In a new study, researchers from the University of Copenhagen have managed to completely block the development of obesity. The researchers deleted an enzyme and made it impossible for mice to increase their amount of fat tissue, despite the mice eating
