Stressed intestine can give rise to food allergy

The intestines of mice which have been subjected to stress, overreact to certain nutritional substances. PhD biologist Annette van Kalkeren from the University of Amsterdam has investigated the relationship between stress and the occurrence of food allergies and various intestinal disorders.

The biologist investigated the reaction of pieces of mouse intestine to egg albumin, a substance found in eggs. Just like humans, mice can become allergic to the substance. However, mice only become alle

Discovery of method to combat toxic algal blooms and description of a new group of organisms

In the fall of 1997 a then unknown species of plankton, Parvilucifera infectans , was discovered in the Gullmar Fjord, on the west coast of Sweden. The organism is a parasite that infects and kills several species of toxic algae. Some of these toxic algae can generate extremely potent blooms at great cost to fisheries and the tourism industry around the world. Other species cause mussel toxins that cause major problems for mussel farmers in Sweden and elsewhere.

Molecules take electronics for a spin

Researchers eager to use individual molecules as the components of ultra-small electronic circuits and computers have put a new spin on their ambitious goal.

They take advantage of a hitherto unexploited property of electric currents, called spin, to make molecular devices that operate under new rules. This fledgling form of electronics, called spintronics, could lead to computers that don’t forget anything when their

Cells reprogram in 24 hours

Erasing molecular memory of parents could shed light on clones.

Cells naturally wipe out the mark of their parents in 24 hours, say cloning experts. Exactly how may begin to explain the way that animal clones and stem cells are reprogrammed. Not all genes are born equal. In mammals, some genes are imprinted – cells switch on only the copy inherited from mum or dad, not both. This sex stamp must be erased and rewritten in sperm and egg cells, however, so they are correctly labelled as

Giant vesicles, minibeads, and molecular motors : An original system to emulate intracellular transport

Communication, clearly essential to humans, is also essential to cells, their elemental building blocks. In order to preserve organic cohesion, cells need to communicate with their environment, but they also need to ensure adequate communication between their various compartments.

These forms of intracellular exchange are essential and require the setting up of actual networks. Membrane transport tubes were evidenced some years ago, but their formation has up till now remained a mystery.

Death rates during hot weather start rising at relatively low temperatures

The impact of heat on death rates begins at relatively low temperatures during hot weather, finds research in the Journal of Epidemiology and Community Health.

Researchers analysed temperature readings from the Meteorological Office and death rates from the Office of National Statistics for London between 1976 and 1996.

They found that death rates associated with heat started rising at about 19 degrees Centigrade (66 degrees Farenheit), and once above 21.5 degrees Centigrade (abou
