One of the most important principles of physics, that disorder, or entropy, always increases, has been shown to be untrue. Scientists at the Australian National University (ANU) have carried out an experiment involving lasers and microscopic beads that disobeys the so-called Second Law of Thermodynamics, something many scientists had considered impossible. The finding has implications for nanotechnology - the design and construction of molecular machines. They may not work as expected.

A study, released Thursday by private technology investment group 3i along with the Economist Intelligence Unit and the Institute of Nanotechnology says applications for nanotech are largely misunderstood and investors in the area too shortsighted. The study includes the opinions of scientists, academics, and industry experts from around the world. It asserts that nanotechnology can contribute to improvements in a variety of areas impacting aspects of people's lives such as computing, health care, communications, manufacturing, energy and the environment. Nanotechnology is unique in this way, requiring scientists from many different areas to collaborate.

Max Planck scientists use a new type of microscope to make crystal vibrations in the nanometre range visible.Scientists at the Max Planck Institute for Biochemistry in Martinsried near Munich, Germany, have used their infrared near-field microscope to study crystal lattice vibrations (Nature 418, 159, 11th July 2002). They used infrared laser beam illumination of a nano-sized antenna to obtain resonance with the vibrations, the so-called phonon resonance. The new technique makes it possible to find out a crystal's chemical identity, and even its structural quality, both with nanometric resolution.

Mathematicians have achieved a major step towards answering the question of whether numbers like pi and other mathematical constants are truly random and for the first time linked number theory with chaos theory. It is not just a mathematical curiosity they say. Proving that pi never repeats itself would be a major advance in our theory of numbers.
