It’s 99.99 per cent sound absorbent and holds the Guinness World Record for the world’s quietest place, but stay there too long and you may start hallucinating. Earth's quietest place: The 'anechoic chamber' at Orfield Laboratories, which is 99.99 per cent sound absorbent and capable of giving you hallucinations The Anechoic Test Chamber at Orfield Laboratories was deemed the quietest place on Earth in 2004 - a record it still holds to this day It achieves its ultra-quietness by virtue of 3.3-foot-thick fiberglass acoustic wedges, double walls of insulated steel and foot-thick concrete. The company’s founder and president, Steven Orfield, told MailOnline: ‘We challenge people to sit in the chamber in the dark - one reporter stayed in there for 45 minutes. ‘When it’s quiet, ears will adapt.

BBC News - Meteorites delivered gold to Earth
A burst of meteorite impacts around 3.9 billion years ago delivered precious metals to Earth A study from the University of Bristol looked at some of the oldest rocks on Earth, demonstrating that gold was delivered by meteorites long after their formation. Any precious metals in the planetary mix would have gone with this iron and concentrated in the core, leaving the mantle devoid of elements such as gold, platinum, and osmium.

Government Study Proves THC from Cannabis Destroys Cancer Cells

(PhysOrg.com) -- The flickering flame of a candle has generated comparisons with the twinkling sparkle of diamonds for centuries, but new research has discovered the likeness owes more to science than the dreams of poets. Since the first candle was invented in ancient China more than 2,000 years ago, many have longed to know what hidden secrets its flames contained. Using a new sampling technique, assisted by his student Mr Zixue Su, he invented himself, he was able to remove particles from the centre of the flame – something never successfully achieved before – and found to his surprise that a candle flame contains all four known forms of carbon. Dr Zhou said: "This was a surprise because each form is usually created under different conditions." At the bottom of the flame, it was already known that hydro-carbon molecules existed which were converted into carbon dioxide by the top of the flame. But the process in between remained a mystery.

Starting from a raster image that is made of large squares, we arrive at a clearer picture, as if one could a posteriori change the definition of the screen on which it was drawn ... Wisely by removing the "noise", ie the image defects such as dots and stripes, and it needs to know to interpret that, the algorithm gives life to a cliche damaged or washed out.

Seven hundred and fifty light-years from Earth, a young, sunlike star has been found with jets that blast epic quantities of water into interstellar space, shooting out droplets that move faster than a speeding bullet. The discovery suggests that protostars may be seeding the universe with water. These stellar embryos shoot jets of material from their north and south poles as their growth is fed by infalling dust that circles the bodies in vast disks.
