A NUCLEAR fusion laboratory designed to re-create the temperatures and pressures of an exploding star could be built in England under plans being drawn up by British scientists.
A supernovae / supernovas is a stellar explosion. They are extremely luminous and cause a burst of radiation that may briefly outshine an entire galaxy before fading from view over several weeks or months. Now scientists plan supernova blasts in lab to tap energy.
The aim is to build some of the world’s most powerful lasers and use them to blast tiny pellets of hydrogen fuel to create energy.
The process is similar to the supernova explosion that heralds the death of a star.
Researchers say the process could offer a partial solution to the world’s energy crisis, offering a source of carbon-free power with only a minimum of radioactive waste.
Since the introduction of mobile phones, concerns have been raised about the potential health impacts from regular use. Now, new research suggests that if you need to make a phone call in the evening it is much better to use a land line instead of a mobile phone. Continue reading “Mobile Phones Can Disturb Your Sleep”
This is an interesting discovery which may lead to provide us more information about life and other factors.
The first evidence of a volcanic eruption from beneath Antarctica’s most rapidly changing ice sheet has been reported. The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth’s southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle.

A dwarf star with a surprisingly magnetic personality and a huge hot spot covering half its surface area is showing astronomers that life as a cool dwarf is not necessarily as simple and quiet as they once assumed.
Using four of the worldâ€™s most powerful telescopes, astronomers have found a bizarrely magnetic star with some very strange features. The M-type dwarf has a massive â€œhot spotâ€, which covers half of its surface area, and an unusually active magnetic field. The star lies about 35 light-years away in the constellation BoÃ¶tes. If these strange â€œanomaliesâ€ turn out to be common for M-type stars, astronomers will have a radically altered view of the ultracool dwarfs.
According to Dr. Edo Berger, Princeton University:
We find a hot spot that covers half of the surface of the star like a giant lighthouse that rotates in and out of our field of view. We still do not know why only half of the star is lit up in hydrogen and if this situation remains unchanged over days, weeks, years, or centuries.
