London, September 10 : Scientists at the University of Chicago have developed magnetic sensors that can work in high temperatures, and thus be used in the ceramic engines of future cars and aircraft.

The researchers have revealed that such sensors can be created by using slightly degrading samples of a well-known semiconductor material, called indium antimonide, which is valued for its purity.

Most magnetic sensors operate by detecting how a magnetic field alters the path of an electron, and they lose this capability when subjected to temperatures reaching hundreds of degrees.

London, September 10 : The UK is giving 133 million dollars to ‘climate-proof’ Bangladesh, i. e., it would help the country prepare for the impacts of climate change.

According to a report by BBC, the money will go on measures such as protecting houses, schools and farms against flooding, and introducing new crop strains.

Aid agencies have welcomed the move, but say poorer countries will need much more money to adapt to climate change.

UN resources for climate adaptation are badly under-funded, they say. The resources currently available for adaptation are grossly inadequate.

London, September 10 : Archaeologists are creating a permanent digital record of shipwrecks around European coasts, in the form of a ''virtual submarine'' that would allow researchers to explore the wrecks from the comfort of their own desks.

According to a report in The Guardian, by recording the precise 3D arrangement of timbers and cargo from the wrecks, the researchers aim to preserve the information they contain about past civilizations even if the wrecks are damaged or destroyed.

Scientists and members of the general public would in future be able to float over the wrecks in a virtual submarine from the comfort of their own desks.

London, September 10 : Scientists at the University of Washington in Seattle have come up with a new scheme that can solve the problem low connection speeds during peer-to-peer (P2P) downloading.

Such problems usually occur when Internet users download P2P content that is stored a long way from their homes, and the online links over thousands of kilometres get tied up delivering it.

The researchers say that their scheme called Proactive Provider Participation for P2P (P4P) can help ease the load.

Their idea is to take the help of Internet service providers (ISPs) in supplying P2P sites with data on the shortest routes between peers.

London, Sept 10 : Thanks to a “naïve mistake” by a junior Labour Party official, British Prime Minister Gordon Brown has landed in a soup for apparently “backing” Democratic candidate Barack Obama ahead of the US presidential elections in November.

In an article written by the Labour official in Brown’s name, heaps of praise have been showered on Obama, and the Democrats’ policy of “generating the ideas to help people through more difficult times” has been hailed.

The article, however, doesn’t mention anything about McCain or his proposed policies.

London, September 10 : Astrophysicists are debating whether the mysterious dark matter is a WIMP (Weakly interacting massive particle), or a CHAMP (Charged massive particle).

According to a report in New Scientist, the mysterious dark matter that makes up most of the material in the universe may actually have an electric charge, a new study suggested. If so, it might help explain why astronomers see so few dwarf galaxies in orbit around larger ones.
