Ticks spread a greater variety of diseases than any other blood-feeding creature, including mosquitoes. Now scientists are developing vaccines that prevent ticks from digesting the blood of their animal or human victim, according to research presented today (Monday 08 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.
“A new solution to controlling tick-borne diseases is to develop vaccines against the ticks and not the microbes that cause
Protein packaging may enhance MRI contrast.
Images of body tissues and organs could soon be brighter and sharper thanks to a technique developed by Italian chemists. They have made the chemical contrast agents used in magnetic resonance imaging (MRI) produce a stronger signal by trapping them in protein cages just 12 millionths of a millimetre (nanometres) or so widesup> 1 .
Such improvements increase the contrast of the images, so they should reveal more detailed
Rumour and secrecy hampers response to report of human clone.
A dearth of information surrounding claims that a woman is pregnant with the first cloned baby is stifling informed scientific judgement or debate. Second-hand reports and rumours highlight a factual vacuum under which a controversial cloning project is proceeding.
Last week, fertility doctor Severino Antinori revealed to Gulf News journalist Kavitha Davies that one of his patients is eight weeks pregnant with a c
New VLT Discovery Pushes Back the Beginnings
Using the ESO Very Large Telescope (VLT), a team of astronomers from The Netherlands, Germany and the USA  have discovered the most distant group of galaxies ever seen, about 13.5 billion light-years away. The Photo shows the sky region near the power
A new type of optical material has been developed by physicists that could replace the electronics used to route the light signals through optical fibre telecommunications networks. It could even provide the basis for future `optical computers` working on light pulses instead of electric signals. At the Condensed Matter conference on Monday 8 April, part of the Institute of Physics Congress in Brighton, Dr David Sharp, a member of Dr Andrew Turberfield`s research team from the University of Oxford, w
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, “I felt excited!” says Dr Lidija Siller, a physicist from the University of Newcastle. “I believe that the data I have explains how this water got trapped underneath the surface”. Dr Siller will be presenting the results of her research – which involves studying photochemical reactions in ice – at the Condensed Matter physics conference on Monday 8 April
Physicists at Glasgow University are using the world`s most powerful laser beam as an atom smasher to simulate conditions inside the Sun and to produce radioisotopes vital in medicine. Professor Ken Ledingham from the Department of Physics at Glasgow and his colleagues from Imperial College and the Rutherford Appleton Laboratory (RAL) are using the world`s most intense laser beam, produced by the VULCAN laser at the RAL near Oxford, to initiate nuclear reactions for a variety of exciting application
Archaeologists of the University of Bonn have just begun the first of three series of excavation programmes in Xkipché on the Mexican peninsula of Yucatán. They are investigating the living conditions of the population shortly before the city was finally abandoned towards the end of the 10th century as well as the city?s role as the residence of local princes during the turbulent period of its decline.
The location of the find is in the vicinity of the world famous ruined city of Uxmal (rece
Time is running out for the clocks that make our computers tick. Scientists have developed a new generation of hardware and software based on the simpler designs of the 1950s.
Asynchronous, or clock-free systems, promise extra speed, safety, security and miniaturisation. The new designs work well in the laboratory and are only awaiting the development of software tools so that they can be produced commercially, says Professor Alex Yakovlev and fellow researchers in the Department of Computin
Scots scientists are playing a key role in a major new research effort which could save Britain’s farmers millions of pounds a year through reductions in fertiliser and pesticide use.
Biotechnology experts at the University of Abertay Dundee, in partnership with two organisations in England, have been awarded £471,000 by the BBSRC (Biotechnology and Biological Sciences Research Council) for a three-year study into the relationship between white clover and a tiny insect.
