The first public release of plant gene chip information is being launched at the Society for Experimental Biology conference in Swansea on Friday 12th April. Scientists from the Nottingham Arabidopsis Stock Centre (NASC), part of a multi-million pound resource network, will announce a newly accessible plant gene chip database which is available through the internet.

Unlike in GATTACA, where a drop of Ethan Hawke`s blood or an eyelash could tell you what genes he had, gene chips can tell you

The phrase “king of the jungle” invariably conjures up the image of a majestic, tawny cat with a fluffy mane framing its face. But in fact not all male lions have big hair. In Kenya’s Tsavo National Park–famed for the man-eating lions that reportedly terrorized railroad workers there in the late 1800s–a number of males lack manes altogether. Exactly why this should be the case–or why any lions should have manes, for that matter–has been difficult to explain. To that end, the results of a new

Some men send flowers, others send chocolates. But one species of fish has a rather unusual method of seducing the opposite sex. Researchers at the Centre of Marine Science, University of Algarve, Portugal, have been studying how the peacock blenny fish secretes pheromones – chemical ‘love’ signals – from an anal gland.

Dr Eduardo Barata observed peacock blenny over the breeding season, when males occupy holes and crevices in the bottom of the sea which they use as nesting sites where female

Many animals are able to rapidly extend their tongues to catch prey. In fact, the chameleon extends its tongue at an acceleration rate of 500 metres per second square – generating 5 times the G force experienced by an F-16 fighter during its most demanding maneouvre! New research presented at the Society for Experimental Biology conference in Swansea today has shed light on exactly how these remarkable feats are achieved.

Dr Johan van Leeuwen of Wageningen University, the Netherlands, sugges

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

Scientists have discovered that plant leaves activate defence mechanisms against plant eating insects within twenty seconds of an insect walking across them. Dr Alan Bown will be presenting the results of his footsteps research at the Society for Experimental Biology conference on Tuesday 9 April.

Dr Bown and colleagues studied the effects of insects traipsing across leaves, observing the chemical responses in the leaves over time. Ten seconds after larvae had crawled across the leaves, supe
