3D-printer with nano-precision

Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University ...

New microtweezers may build tiny 'MEMS' structures

Researchers have created new "microtweezers" capable of manipulating objects to build tiny structures, print coatings to make advanced sensors, and grab and position live stem cell spheres for research.

Trapping butterfly wings' qualities

Butterflies have inspired humans since the time of ancient Egypt, but now they're also inspiring researchers to look toward nature to help create the next generation of waterproof materials for electronics and sensors.

A faster, cheaper method for making transistors and chips

(PhysOrg.com) -- It may soon be possible manufacture the miniscule structures that make up transistors and silicon chips rapidly and inexpensively. Swiss scientists are currently investigating the use of dynamic stencil lithography, ...

Microspiders: Polymerization reaction drives micromotors

(PhysOrg.com) -- Though it seems like science fiction, microscopic "factories" in which nanomachines produce tiny structures for miniaturized components or nanorobots that destroy tumor cells within the body and scrape blockages ...

A sun protection mechanism helps plants to survive

Just as people can get sunburned, plants can also suffer from too much sunlight. To stay healthy, they use an internal "sun protection mechanism." Pierrick Bru, a Ph.D. student working with Alizée Malnoë at Umeå Plant ...

Mushrooms on Mars? Five unproven claims that alien life exists

A recent study claims to have found evidence for mushroom-like life forms on the surface of Mars. As it happens, these particular features are well known and were discovered by cameras aboard Nasa's Mars Exploration Rover ...
