life on Mars

Writing about web page http://www.liebertpub.com/prdetails.aspx?pr_id=693

how cool would that be if we came from one of the hot springs on Mars????
spiders are said to travel through inter-stellar space and a few years ago virii were supposedly traveling towards Earth from … Mars. Is there (however tiny) chance of a hot spring sending a couple of cells over to Earth?
it may all be just a theory, but scientists in charge of Mars Reconnaissance Orbiter (MRO) are saying that some life forms might have evolved around these hot springs just as it does on Earth. next missions to Mars are likely to look for and study such places of interest.

for those who like to discuss climate change, here is something to think about: blogspot

EDITED:
ha, here is another one :)

UCD galaxies

Writing about web page http://www.ras.org.uk/index.php?option=com_content&task=view&id=1556&Itemid=2

astrophysicists from Germany have concluded that in the early universe stars which made up UCDs (Ultra Compact Dwarf galaxies) were 1000 times closer to each other than the relative distances to nearest stars from our solar system.
it does not come as a surprise though that the UCDs have greater mass than spectroscopy might suggest, i.e. massive black holes might be the key to this problem. it is quite an accurate suggestion as the stars were packed so close that they would form more massive stars that would burn out of hydrogen much quicker, ending their lives as supernovae. the remnants of these great explosions are the neutron stars or black holes yet closely packed inside of the space which is 1/1000th of the size of our Milky Way.

space crash

Writing about web page http://news.bbc.co.uk/1/hi/sci/tech/7885051.stm

quick release:- two communication satellites that of US and Russia have recently collided and completely destroyed each other. it is said to be the first incident of this kind in the history of mankind.
the impact created space-debris and is yet to be fully evaluated by scientists in the US. why are the Russians not bothered? – simply because their spacecraft had gone past its life-cycle limit and was out of operation on the day of collision.

1,000 movies on my USB pen–drive????

Writing about web page http://live.psu.edu/story/37562

Plasmonics is set to give superhigh speeds and comparatively small-sized circuits that will drive our computers 1000’s times faster than today. it is an optimistic call following spintronics’ recent achievements creating faster and more reliable drives.
will it be under-funded spintronics of the UK or an over-enthusiastic plasmonics of the US that will pave the way to a new world of high-end computing?
