A bizarre-looking network of Martian mineral ridges has been spotted by NASA's Curiosity rover. According to team of scientists, the two-tone veins have indicated that there were separate stretches of time during the wet situations in the area that Curiosity is studying at present.

The researchers said the ridges rise as high as 2.5 inches above the level of the bedrock at a site nicknamed Garland City. Rock samples that drilled from three targets lower on the mountain in the past seven months have been examined by Curiosity. A different mineral composition has been found involving a silica mineral named cristobalite in the latest sample.

The European Space Agency's spacecraft Rosetta recently went 8.6 miles (14 km) of comet 67P's surface. During its close flyby, the probe was managed to capture a stunning four image montage showing the two lobes of the icy comet in incredible detail.

The top right frame offers a stunning view onto Hapi, the comet's 'neck' region that is littered with boulders.

The view also gave a detailed look at the numerous, curved markings visible on the smooth surface. In the similar frame, details in the cliff of Hathor were clearly visible, leading up to the head of the comet's small lobe.

The area towards the right of the frame showed the transition between the smooth, presumably dust-covered portion, and the layered, exposed the cliffs below.

NASA has selected Morehead State University (MSU) as one of the 12 Next Space Technologies for Exploration Partnerships (NextSTEP).

The partnership aims to advance concept studies and technology development projects in the areas of advanced propulsion, habitation and small satellites.

NASA's contract with MSU at $7.9 million is one of the biggest in the history of the university, said sources.

Dr. Ben Malphrus, MSU's Department of Earth and Space Sciences chair and Space Science Center director, said in a statement that they are very happy as well as excited about the opportunity.

Researchers believe that the world's smallest gyroscope could be created with the help of light waves. The smallest gyroscope could be developed with a pair of light waves wherein one zips clockwise and the other counterclockwise around a microscopic track.

A team of applied physicists is confident that this essential technology will pave the way for creation of a new generation of phenomenally compact gyroscope-based navigation systems.

"We have found a new detection scheme that may lead to the world's smallest gyroscope. Though these so-called optical gyroscopes are not new, our approach is remarkable both in its super-small size and potential sensitivity", said Li Ge, a physicist at the Graduate Center and Staten Island College, City Univ. of New York.

Colorado became the first state to allow recreational marijuana sales last year. And now, millions of tax dollars are rolling in for funding school construction, marijuana education campaigns and armies of marijuana inspectors and regulators.

But under a legal snarl, the state may be forced to return that money to marijuana consumers, growers and the public, which the lawmakers do not want to do.

A strict anti-spending provision in the state Constitution, touching every corner of public life, like school funding, state health care, local libraries and road repairs, is the main problem.

Springfield city employees participated in National Walking Day. The event began with a rally where an official announcement for 'National Walking Day' was made by Mayor Pro-Tem Jerry Compton. The event was finished with a brief walk near government plaza.

Americans are being invited by the American Heart Association to take a brisk walk. According to Stephen Hall from the American Heart Association, "What we know is that for every hour of regular vigorous exercise, you can gain two hours to your life expectancy. That's a huge rate of return. Walking has the lowest dropout rate. It's free. It's accessible to people".
