Microscopes are not the only tools available to study disease. A new ESA project employs satellites to predict and help combat epidemic outbreaks, as well as join the hunt for the origin of the deadly Ebola virus.

Ebola haemorrhagic fever kills many people in Central Africa each year. It can cause runaway internal and external bleeding in humans and also apes. What remains unidentified is the jungle-based organism serving as the virus’s host.

Researchers at Purdue University are creating interactive software that artists could use to make realistic animations of cloud formations, explosions, smoke, steam, fog and other gaseous phenomena for movies and video games.

The same software might also be used by meteorologists to create accurate representations of quickly developing weather conditions. Because the software is interactive, it shows results immediately, whereas conventional programs might take hours to complete such anim

Oxford scientists have found the first sign that many patients with type 2 diabetes have something wrong with their hearts which has previously been undetected.

More than 90 per cent of all diabetics have type 2 diabetes, and researchers studying a group of type 2 diabetics with no apparent heart problems discovered that their hearts were actually working significantly less efficiently than non-diabetic individuals.

Professor Kieran Clarke led the study at Oxford. “We used

ESA PR 44-2003. A unique view of our home planet and its natural satellite – the Moon – is one of the first data sets coming from ESA’’s Mars Express.

“It is very good news for the mission,” says ESA’’s Mars Express Project Scientist, Agustin Chicarro. These and other data, such as those recording the major constituents of Earth as seen from space, are the actual proof that the instruments on board Mars Express, launched 2 June 2003, are working perfectly.

Using the powerful trick of gravitational lensing, a European and American team of astronomers have constructed an extensive ‘mass map’ of one of the most massive structures in our Universe. They believe that it will lead to a better understanding of how such systems assembled and the key role of dark matter.

Clusters of galaxies are the largest stable systems in the Universe. They are like laboratories for studying the relationship between the distributions of dark and visible matter. In 1

Using a tool kit of lasers, tiny beads and a Lego set, Howard Hughes Medical Institute researchers have made the first measurement of the torsional, or twisting, elasticity of a single molecule of DNA.

The measurements reveal that DNA is significantly stiffer than previously thought and, when wound, may in fact provide enough power to be used as a sort of molecular, rubberband motor to propel nanomachines. Although that type of application may be well in the future, the studies are si
