A scientist who studies the phsyics of sperm “as a hobby” is challenging the current understanding of how sperm swim towards an egg. At the Society for Experimental Biology conference today Dr Christopher Lowe will present the results of his modelling of a sperm`s tail, suggesting we may need to re-think our assumptions of how sperm move through fluid.

Experimental studies of sperm have generated a fairly well established database of parameters on sperm movement. The frequency and wavelength

Broccoli is one of western Europe`s most popular and widely consumed vegetables. However, its shelf life is restricted to about 5 days at room temperature, making distribution and storage of the product difficult. Recent research presented today at the Society for Experimental Biology conference in Swansea could help us understand the genetics of this situation and may even lead to `supervarieties` of broccoli.

The popularity of broccoli is on the increase and it is used increasingly in valu

Positioning systems will become an essential tool for the carrying out of many different tasks in the future. Whether the problem consists of a tree falling on a power line or a car standing in the road with a motor failure, aid services will find a route straight to the right location by using this system.

It has previously been difficult for a person in need of aid to convey exact information about his location in an unfamiliar area. In future, the person can find his exact location with t

Every night 2.1 million newspapers are delivered to mailboxes in Finland. In order to make the delivery even more effortless, wireless data transfer will be harnessed to aid newspaper carriers.

In the three-year TLX technology programme recently completed by Tekes, the Technical Research Centre of Finland (VTT) has investigated methods of wireless control and monitoring of the newspaper delivery chain.

“In addition to various portable devices like mobile phones and PDA computers, i

Asymmetric bodies fuel arguments over ecological risk.

Birds with one foot bigger than the other are showing signs of stress, say Belgian ecologists. The study backs the controversial idea that measuring body asymmetries could signal that a species is at risk.

Researchers at the University of Antwerp measured the feet of taita thrushes from three remaining pockets of their native forest in Kenya. Those from the most disturbed area showed eight times more difference between t

The effectiveness of many potentially powerful treatments including drug therapy, gene therapy and cancer chemotherapy is often reduced because it can be difficult to target the treatment exactly where it will be most effective. One of the problems is that it is frequently difficult for drugs, as well as DNA and other biological molecules, to pass through the membranes of the targeted cells. Electroporation (EP), which involves the application of electrical pulses directly to the tissue to be treated
