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

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

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

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

The absence of a key signaling protein in the brain during infancy could lead to anxiety disorders later in life, scientists say. According to findings published today in the journal Nature, mice lacking the receptor protein for the chemical messenger serotonin just after birth exhibit abnormal anxiety as adults.

Researchers have known for some time that mice genetically engineered to lack the receptor for serotonin, a neurotransmitter, show anxiety-like behavior. But the new results go one

In recent years, new food packaging concepts have been developed to respond on consumption trends towards mildly preserved, fresh convenient food products. Fresh-cut vegetables are an example of fresh-like, healthy convenience foods, developed in the ‘80s in the UK. Their market is yearly increasing with 25% in West Europe.

Packaging fresh-cut vegetables under an Equilibrium Modified Atmosphere (EMA) is one of the new applied food packaging technologies offering a prolonged shelf-life of re
