Jumping robots may soon find role in military service

London, May 10 (ANI): Robots that can leap 8 metres vertically to clear walls or fences may soon find themselves in the military.

Sandia National Laboratories' prototype Urban Hopper can really do wonders just by hopping.

Now robot maker Boston Dynamics has landed the job of producing a military version with a dash of more self-control.

US Defense Advanced Research Projects Agency (DARPA), which is funding the programme, says it wants the hopper for urban reconnaissance and intelligence gathering - although it admits it could also be fitted with a raft of weapons, reports New Scientist.

Sandia's shoebox-sized prototype, which is driven by an electric motor, rolls along on wheels. It jumps using a gas piston which is powered by methylacetylene and nitrous oxide.

However, its leaps so far are pretty haphazard.

"The existing hoppers do not maintain a stable orientation during hops, but tumble randomly," says DARPA spokesman Mark Peterson. (ANI)

New finding 'challenges current assumptions' about jumping genes

Washington, June 12 (ANI): Challenging standard assumptions about mobile DNA, or the so-called jumping genes, scientists have found that such genes do most of their jumping not during the development of sperm and egg cells, but during the development of the embryo itself.Jumping genes - also called transposons - are sequences of DNA that can move or jump to different areas of the genome within the same cell, and can be a rare cause of certain diseases like hemophilia and Duchenne.....
