Hair-sized lens helps look in blood vessels

A tiny measurement system that incorporates a lens as thick as two human hairs has been developed by researchers to investigate the force exerted on the wall of an artery as blood whooshes past. In a research paper published today in the Institute of Physics publication Journal of Micromechanics and Microengineering, Dr Rob Keynton and colleagues at the University of Louisville, Kentucky and Michigan Technological University, USA describe how they have designed and made an integrated miniature acous

Non-collapsing knots could reveal secrets of the Universe

A computational trick that stops imaginary knots collapsing could help us understand how to unravel a loop of DNA or reveal the true nature of elementary particles, research published today suggests.

In the New Journal of Physics, published jointly by the Institute of Physics and the German Physical Society, Phoebe Hoidn and Andrzej Stasiak of the University of Lausanne, Switzerland, and Robert Kusner of the University of Massachusetts, USA, explore the mathematical complexities of particula

Maths cracks egg flip

Friction pushes a spinning egg from horizontal to vertical.

Mathematicians have cracked the conundrum of the spinning egg. A hard-boiled egg spun on its side flips upright because of friction between the egg and the table, they calculate 1 .

The egg’s elevation appears paradoxical. Its centre of gravity moves up – making the system seem to be gaining energy.

In fact, spinning energy, translated into a horizontal force, pushes the egg upright, sa

A new project to test a pioneering method to advance technology

Technological advances take place all the time – driven by need. But can these advances be speeded up in quantum leaps? The European Space Agency thinks they can, and is launching a pioneering project to test this.

The European Space Agency has launched a project to test whether technological advances can be speeded up in quantum leaps. The Star Tiger project will gather together a small team of enthusiastic scientists and engineers with a range of expertise from around Europe, put them toge

New environmental research lab helps get more out of waste

A new London research laboratory developing fresh solutions to the perpetual problems of how best to get rid of our waste has reopened its doors today after a UKP1.5 million facelift.

Researchers based in the new Roger Perry Environmental Engineering laboratory at Imperial College are behind a number of innovative new waste reclaim and reuse projects.

Over 60 London households are helping in one project to evaluate how effective home composting is at managing domestic solid waste, t

Diverse Viruses Show Signs of Common Ancestry

The viruses that cause diseases as varied as AIDS, hepatitis and West Nile Virus may actually have more in common than was previously thought, new research reveals. According to a study that will appear in the March issue of the journal Molecular Cell, three major groups of viruses use similar mechanisms to replicate their genetic information after they have infiltrated the cells of a host.

There are six broad classes of viruses, each thought to represent a major evolutionary lineage. M
