Equations reveal rebellious rhythms at the heart of nature

Posted: 20 Jun 2014 09:03 AM PDT

Physicists are using equations to reveal the hidden complexities of the human body. From the beating of our hearts to the proper functioning of our brains, many systems in nature depend on collections of 'oscillators'; perfectly-coordinated, rhythmic systems working together in flux, like the cardiac muscle cells in the heart.

Princess and the Pea? Invisibility cloak prevents an object from being felt

Posted: 20 Jun 2014 07:23 AM PDT

In the past years, invisibility cloaks were developed for various senses. Objects can be hidden from light, heat or sound. However, hiding of an object from being touched still remained to be accomplished. Scientists have now succeeded in creating a volume in which an object can be hidden from touching similar to a pea under the mattress of a princess.

Jupiter's moons remain slightly illuminated, even in eclipse

Astronomers have found that Jupiter's Galilean satellites (Io, Europa, Ganymede, and Callisto) remain slightly bright (up to one millionth of their normal state) even when in the Jovian shadow and not directly illuminated by the Sun. The effect is particularly pronounced for Ganymede and Callisto.

Lopwood, brushwood make high-grade charcoal

When the forestry machines have finished extracting timber, what is left are tops and branches – waste which cannot be used. However, according to researchers, it is possible to turn these heaps of lopwood into high-quality charcoal. One researcher proclaims that this could revolutionize the bio-energy production industry.

Better imager for identifying tumors

Posted: 19 Jun 2014 12:41 PM PDT

A new technique that could improve surgeons' ability to identify cancerous tumors and remove them in real-time in the operating room has been developed by researchers. The new imaging system combines two techniques -- near-IR fluorescent imaging and visible light reflectance imaging -- to get a much better picture of the tissue.
