When you hear the word "shapeshifting" you probably think of a sci-fi or horror film, and not the climate. But that's what scientists say is happening to some animals in response to climate change. Warm-blooded species are evolving to have larger beaks, legs and ears to regulate body temperature as the planet warms up, a new study suggests. The scientists behind the study warn the physiological changes do not mean animals are coping with climate change. "A lot of the time when climate change is discussed, people are asking 'can humans overcome this?' or 'what technology can solve this?'" says...

Bacterial cells treated with a common antibiotic have been spotted changing shape to survive while aboard the International Space Station (ISS). The way bacteria act in near-zero gravity environments could pose a serious problem for treating astronauts with infections. ... An experiment on the common E coli bacteria subjected it to different concentrations of the antibiotic gentamicin sulfate, a drug which kills the bug on Earth. However, in comparison to a control group on Earth, the space bacteria showed a 13-fold increase in cell numbers and a 73% reduction in cell column size. "We knew bacteria behave differently in space...

How phony is Barack Obama? PBS Washington Week host Gwen Ifill reviewed New Yorker editor David Remnick's new Obama book The Bridge in the Washington Post Outlook section Sunday, and she kept finding Obama is a Slick Barry, a "shape shifter." Obama even admitted to rhetoric what should be obvious -- how he changes "dialects" depending on the audience he's talking to: Obama cops to this. "The fact that I conjugate my verbs and speak in a typical Midwestern newscaster's voice -- there's no doubt that this helps ease communication between myself and white audiences," he tells Remnick. "And there's...

A new shapeshifting chemical robot being developed for Defence Advanced Research Projects Agency (DARPA) and the US Army has been unveiled by Pentagon researchers. ChemBot is a small mobile device that looks like a gelatinous blob, it can change shape to navigate through tight spaces and will be used by the army for intelligence gathering, and search and rescue missions. The chemical robot moves from place to place by way of a process called 'jamming' which causes the material to transition between semi-liquid and semi-solid states with only a slight change in volume. Jamming technology allows the scientists to make...

Small robotic spy-planes have been developed that use shape-shifting wings to switch from being stable gliders to ultra-manoeuvrable fliers. The articulated wings – with a span of 60 centimetres – were inspired by the way seagulls alter their wing-shape during flight, says Rick Lind, an aerospace engineer at the University of Florida, in Gainesville, US. The robot plane, or drone, has a joint halfway along the leading edge of both its wings. Actuators at this “elbow” joint and at the “shoulder” joint of each wing, where it connects to the fuselage, allow the wing structure to shift from an...

TINY robots that can turn into any shape - from a replica human to a banana to a mobile phone - are being developed by scientists in the United States. The new science of claytronics, which will use nanotechnology to create tiny robots called catoms, should enable three-dimensional copies of people to be "faxed" around the world for virtual meetings. A doctor could also consult with a patient over the phone, even taking their pulse by holding the wrist of the claytronic replica, reports New Scientist. And the nano "clay" could be carried around, shape-shifting into virtually anything when required....
