One of Leonardo da Vinci's masterpieces, a self-portrait, was drawn in red chalk on paper during the early 1500s. As you can imagine, a chalk drawing on paper from the Renaissance is in extremely…

A team of researchers has developed sperm-inspired microrobots which can be controlled by oscillating weak magnetic fields.  The 322 micron-long robots consist solely of a head coated in a thick…

Researchers of the Universitat Politècnica de València at the Campus de Gandia have designed and experimentally evaluated a new structure that permit the complete absorption of sound at a wide range…

What makes the perfect beer foam? Is it nucleation in the glass? Beer is well-traveled ground on Science 2.0 and that means beer foam has been covered as well. The biggest advice. Be careful with the…

In light of recent results from the "world's longest experiment", spanning more than 90 years, at the University of Queensland, a group of researchers from Trinity College Dublin explain the…

In a previous article I wanted to know if I could use the recording medium from old floppy disk as an infrared (IR) filter to shoot infrared photography on an iPod. I built a simple IR detector using…

SensaBubble is a chrono-sensory mid-air display system that generates scented bubbles to deliver information to people using different senses. The bubble-based technology creates bubbles with a…

While creating new springs to support a cephalopod-inspired imaging project, a group of Harvard researchers stumbled upon a surprising discovery: the hemihelix, a shape rarely seen in nature. Helices…

In Tom Wolfe's "The Right Stuff" and in 1940s engineering, there was a demon in the air at 750 miles per hour, a line some said could not be crossed. It was called the Sound Barrier for that reason.…

The Science Play and Research Kit (SPARK) competition winners were announced today. The SPARK competition was a challenge to “reimagine the chemistry set for the 21st Century,” according to the…
