Winners of $20M contest make concrete to trap carbon dioxide

Organizers of a $20 million contest to develop products from greenhouse gas that flows from power plants announced two winners Monday ahead of launching a similar but much bigger competition backed by Elon Musk.

Using sound waves to make patterns that never repeat

Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in materials ...

Nonlinear wave mixing facilitates subwavelength imaging

The diffraction limit, also known as the Abbe diffraction limit in optics, poses a great challenge in many systems that involve wave dynamics, such as imaging, astronomy, and photolithography. For example, the best optical ...

At the crossroads of cell survival and death

National University of Singapore researchers discovered that a protein, known as MOAP-1, plays a crucial role in facilitating autophagy, a cellular "self-eating" process that recycles non-essential components during starvation.

Effective Field Theories and the nature of the universe

What is the world made of? This question, which goes back millennia, was revisited by theoretical physicist Steven Weinberg from the University of Texas in Austin, TX, USA in the first of an international seminar series, ...

Modification of graphene using laser light

Graphene is an exciting new material, which has been characterized as a 'wonder material' because of its excellent properties. Graphene gained widespread attention in 2010 when the Nobel Prize in physics was awarded to researchers ...
