Patients who have been newly diagnosed with breast cancer now have access to the experiences of other people living with the disease via the multi-media website DIPEx (Database of Individual Patient Experiences), a resource of patient interviews in written form, audio and video clips. From today [13 Feburary 2002] the DIPEx website includes a new module on breast cancer, in addition to hypertension and prostate cancer.
The aim of the new module is to prepare those diagnosed with breast cancer fo

Reptile history reveals daring escape from Madagascar

Land-lubber chameleons navigated the oceans to spread around the world. Stowed away on tree rafts, the animals were ferried to distant shores, new research suggests 1 .

Chameleons aren’t good swimmers: their mitten-like feet are made to grasp twigs and trees. Yet the intrepid animals charted the seas several times in the past 26 million years, say Chris Raxworthy of the American Museum of Natural History i

The mealybug Phenacoccus herreni feeds on cassava plant sap, inducing shrivelling. It causes extensive damage in cassava growing areas in South America. However, it can be parasitized by two wasps, Acerophagus coccois and Aenasius vexans which act out a ritual to recognize and select the individuals they are going to parasitize. A wasp moves from one side to the other of a potential victim, investigating it by palpation with their antennae. Once this “drumming and turning” procedure completed, the wa

Large scale study spells out links with pregnancy and miscarriage.

Childless women are at a higher risk of developing breast cancer, confirms one of the largest studies on reproductive factors and the disease, but those who suffer miscarriages are not. Researchers are pinning down key risk factors in the hope of working out exactly how they increase susceptibility.

How pregnancy and abortion alter women’s chance of developing breast cancer has been the subject of conflictin

Our skin takes its oxygen straight from the air.

The James Bond movie Goldfinger spawned the urban myth that a person can suffocate if air cannot reach their skin. But the plot contains a grain of truth, new research reveals – our skin gets its oxygen from the atmosphere, not the blood.

Air supplies the top 0.25-0.4 mm of the skin with oxygen, dermatologist Markus Stücker of the Ruhr-University in Bochum, Germany, and his colleagues have found. This is almost 10 times

Average insect brain should help spot defects and their causes.

Two hair’s breadths long and five across – that’s the average capacity of a fly’s brain, German researchers have calculated. They hope to set a benchmark for crania by which oddballs can be judged.

Although it is a creature of little brain, the fruit fly ( Drosophila ) is popular with geneticists. Researchers often study flies that lack a particular gene, looking for flaws that might hint at
