Lord Rees said he believed that astro-physicists could be able to view images of distant planets outside the solar system as soon as 2025. This could potentially lead to the discovery of some form of life on them.

FILLING a cup from this tap would take 40,000 years, but luckily its raison d'être has nothing to do with quenching thirst. The trickle in question flows along a silicon chip and is the slowest ever recorded. Its detection should speed up the creation of the first fully electronic lab-on-a-chip.

The Curiosity rover is making good progress towards its first major science destination on Mars.The vehicle has now driven 289m (950ft) since its landing on the Red Planet some six weeks ago.
Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have discovered a way to use sound waves to levitate individual droplets of solutions containing different pharmaceuticals. While the connection between levitation and drug development may not be immediately apparent, a special relationship emerges at the molecular level.

Sharing more leads to tighter bonds – even in the world of molecules. The most detailed images yet made of the chemical bonds in a molecule vividly show what large-scale models had long assumed: the more electrons two atoms share, the shorter the bond. Bonds that are more electron-dense also appear brighter in the new images.
Sand Sifter This image shows the open inlet where powered rock and soil samples will be funneled down into the Mars rover Curiosity for analysis. It was taken by the Mars Hand Lens Imager (MAHLI) on Curiosity's 36th Martian day, or sol, on Mars (Sept. 11 on Earth). MAHLI was about 8 inches away from the mouth of the Chemistry and Mineralogy (CheMin) instrument when it took this picture. The entrance of the funnel is about 1.4 inches in diameter and the mesh screen is about 2.3 inches deep. Once the samples have gone down the 0.4-inch holes in the funnel, CheMin will be shooting X-rays at the samples to identify and quantify the minerals. Read more about what CheMin can do here.

This image shows the entrance to the CheMin instrument (for Chemistry and Mineralogy), which will sift Martian dirt so it can be X-rayed. CheMin will identify minerals by examining the diffraction patterns of X-rays that pass through the spaces between atoms.
Named NU-109 and NU-110, the materials belong to a class of crystalline nanostructure known as metal-organic frameworks (MOFs) that are promising vessels for natural gas storage for vehicles, catalysts, and other sustainable materials chemistry.
|The experiment requires preparing pairs of "entangled" photons, the particles from which light is made|
University of Bristol’s Centre for Quantum Photonics have developed a silicon chip that will pave the way to the mass-manufacture of miniature quantum chips. The announcement was made at the launch of the 2012 British Science Festival [4 to 9 September].
This video shows a simple kinesthetic activity that models the life cycle of a star with a mass similar to our sun.
reported this week in the journal Physical Review Letters, MIT physicists have imposed a stringent set of traffic rules on atomic particles in a gas: Those spinning clockwise can move in only one direction, while those spinning counterclockwise can move only in the other direction.
Here's a frankfurter that won't fit on a bun. Hot dust-obscured galaxies, or hot DOGs, are a new type of cosmic object that could help answer a decades-old problem: which came first, the galaxy or the black hole?
The newly discovered galaxies are among the brightest in the universe, 1000 times brighter than the Milky Way, but they are so heavily clouded by dust that they had gone entirely unnoticed until now – hence the description "hot, dust-obscured".
