It has often been claimed that psychological stress is an important cause of heart disease, but a study in this week’s BMJ shows that previous research may have been misleading.

Researchers measured self-assessed stress amongst middle-aged Scottish men working in and around Glasgow in the early 1970s. These men were then followed for more than twenty years to see whether or not they developed heart disease. Several different measures of heart disease were used.

Men who thought they

In a joint project with the STW Technology Foundation, medical information technologists from Leiden have developed a virtual robot which meticulously scans the heart muscle using images of the heart. The contours detector reduces the work of specialists and does not affect the patients. The research group will present the results in the middle of May at a congress in Honolulu.

To map the condition of a patient’s heart, physicians have until now used a series of MRI images (magnetic resonanc

An international team of scientists from Cambridge, Manchester and Tenerife has released the first results of new high-precision observations of the relic radiation from the Big Bang, often called the cosmic microwave background or CMB.

These observations have been made with a novel radio telescope called the Very Small Array (VSA) situated on Mount Teide in Tenerife. The images show the beginnings of the formation of structure in the early Universe.

From the properties of the image

A signature of arts and crafts sessions, the Möbius strip–a seemingly endless ribbon with only one side and one edge that can be made from construction paper and sticky tape–has been given a new look. According to a report published today in the journal Nature, scientists have succeeded in growing crystals in the form of Möbius structures.

A piece of ribbon or paper can be twisted and turned easily, so a regular Möbius strip itself is no great feat of engineering. Crystals, in contrast,

Activity Generates New Nerve Cells For Old Mice – Study Supports Link Between Active Life And Lower Risk Of Neurodegenerative Disease

Active older people seem to have a lower risk of certain neurological disorders such as Alzheimer`s disease. A study published May 22 in the on-line edition of the Annals of Neurology, the research publication of the American Neurological Association, demonstrates how this increased activity might protect the brain.

Breastfeeding might protect against cot death, suggests research in the Archives of Disease in Childhood.

The researchers surveyed the parents of 244 babies who had died of sudden infant death syndrome (SIDS) and 869 babies still alive and well to find out how they had been fed. The study was conducted between 1992 and 1995. Over 80 per cent of the SIDS baby parents and almost three quarters of the comparison group responded.

During the study period breast feeding among the c
