Glowing nanobots map microscopic surfaces.
Unleashing hordes of molecular robots to explore a surface’s terrain can produce maps of microscopic structures and devices with higher resolutions than those produced by conventional microscopes, new research shows.
Each robot has a ’light’ attached to it, allowing its random movements to be tracked around obstacles, through cracks or under overhangs. Adding the paths of hundreds of wandering nanobots together builds up a map of th
The phrase `rain stopped play` is gloomily familiar to fans of Wimbledon, international cricket test matches and other major sporting tournaments.
But cancelling matches because the pitch is waterlogged could be consigned to history, thanks to new technology which could revolutionise the international world of both professional and amateur sport.
Researchers at the University of Newcastle upon Tyne are starting trials involving a completely new concept – Electrokinetic Geosynthetic
It is possible to measure levels of the stress hormone cortisol not only in blood but also in saliva. Linköping physician Elisabeth Aardal-Eriksson has further developed a saliva test to make it reliable and easy to use, not only in hospitals but also in the field. The findings are presented in a dissertation at Linköping University, Sweden. The researcher has also found that the corisol content of saliva is related to the occurrence of so-called posttraumatic symptoms of stress.

Thanks to ion propulsion, the Artemis mission is turning near-defeat into a success story. Nominal operations could start this summer, with ESA’s satellite, manufactured by Alenia Spazio as prime contractor (I), playing a significant role in the pursuit of high technology and advanced telecommunications.
On 12 July 2001, 30 minutes after lift-off from Europe’s spaceport in Kourou, French Guiana, it became apparent that the Ariane 5 launcher had propelled the Artemis satellite into a transf
In the edition of Nature dated Thursday 21 February 2002, an international team of scientists report their analysis of the genome of fission yeast (Schizosaccharomyces pombe). The project, largely funded through a €6.9 million from the European Commission, is likely to have major implications for the future of cancer and other bio-medical research. Fifty of the yeast genes were found to have significant similarity with genes involved in human diseases, including cystic fibrosis, hereditary deafness a
Alternative yeast joins genome party.
First there was budding yeast ( Saccharomyces cerevisiae ). Partly responsible for scientists survival by fermenting their staples beer and bread, they polished off its DNA sequence back in 1997.
Now the minority fungus of lab culture – fission yeast ( Schizosaccharomyces pombe ) – is fighting back. This week S. pombe enters the experimental big leagues, with the announcement of its completed genome 1
