Hubble Reveals Weird New Waterworld

Would Kevin Costner’s character in the movie “Waterworld” be at home on this exoplanet? The planet GJ 1214b was discovered in 2009 and was one of the first planets where an atmosphere was detected. In 2010, scientists were able to measure the atmosphere, finding it was likely composed mainly of water. Now, with infrared spectra taken during transit observations by the Hubble Space Telescope, scientists say this world is even more unique, and that it represents a new class of … Continue reading

Brian Cox answers his critics – Video

On Sunday the 18th of December 2011 Deskarati watched Prof. Brian Cox present a program on the BBC entitled ‘A Night with the Stars’. This was an excellent introduction to the world of science and we enjoyed it immensely. But a particular part of the program, shown in the clip above, caused some consternation from the viewers and indeed surprised us somewhat. In the program he inferred that all electrons in the universe are in constant communication  and no two of them are ever in the same state. He demonstrated … Continue reading

Time crystals could behave almost like perpetual motion machines

As every young science student knows, moving objects have kinetic energy. But just how much energy does something need to move? In a new study, a pair of physicists has shown that it’s theoretically possible for a system in its lowest energy state, or ground state, to exhibit periodic motion. This periodically moving system can be thought of as the temporal equivalent of a crystal, which is defined by its spatial periodicity. What’s even more intriguing about these “time crystals” … Continue reading

Tuberculosis researchers find answer to 30-year-old puzzle

After three decades of searching, the random screening of a group of compounds against the bacterium that causes tuberculosis has led scientists to a eureka discovery that breaks through the fortress that protects the bacterium and allows it to survive and persist against treatments. The two findings, which occurred at Colorado State University, are published today in Nature Chemical Biology. The article describes the discovery of an important cell function in the bacterium that causes tuberculosis which allows the bacterium … Continue reading
