Hubble Space Telescope Sees Evidence of Water Vapor Venting off Jupiter Moon


NASA's Hubble Space Telescope has observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface. Previous scientific findings from other sources already point to the existence of an ocean located under Europa's icy crust. Researchers are not yet certain whether the detected water vapor is generated by water plumes erupting on the surface, but they are confident this is the most likely explanation.

Should further observations support the finding, it would make Europa the second moon in the solar system known to have water vapor plumes. The findings were published in the Thursday, Dec. 12, online issue of Science Express, and reported at the meeting of the American Geophysical Union in San Francisco.
This is an artist's concept of a plume of water vapor thought to be ejected off the frigid, icy surface of the Jovian moon Europa, located about 500 million miles (800 million kilometers) from the sun.

An Artificial Hand with Sense of Touch

There have been excellent advances in prosthetic limbs in some previous years. But with all such advancements it is still not possible for prosthetic limbs to send information back to the wearer and its making it harder for them to do a pick up object task without crushing them and losing their grip.

Now researchers have developed  a new interface that can convey a sense of touch from 20 spots on prosthetic hand by directly stimulating nerve bundles also known as peripheral nerves in the arms of patients. So this interface can let user feel what they are picking up.

There is a video shown below of a 48 year old man who lost his right hand in a accident but now using a prosthetic hand to pick up and remove stems from cherries without crushing and squeezing them.

inFORM- a Dynamic Shape Display by MIT scientists...

Two MIT Phd students Daniel Leithinger and Sean Follmer, have created inFORM a Dynamic Shape Display in early November this year that can reproduce digital content physically in 3D, which allows you to interact with it or this could be the future of PC interaction.

inForm allows someone on one side of video screen to physically interact with objects sitting on other side.

inFORM, a futuristic shapeshifting display that allows you to not only physically interact with digital content, but hold hands with another person from hundreds of miles away.The inFORM can be used for everything from physically rendering bar graphs and 3D models which you can touch like you would any other object. And forget Skype calls; the inFORM can create a physical version of someone who, for example, rings into a conference call from afar. 

Watch this video and feel the future...

"Blue Marble" The First Photograph of Earth..



On this date in history, Dec. 7, 1972, the Apollo 17 crew snap this iconic "blue marble" photograph of the Earth. This is the original caption: View of the Earth as seen by the Apollo 17 crew traveling toward the moon. This translunar coast photograph extends from the Mediterranean Sea area to the Antarctica south polar ice cap. This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the Southern Hemisphere. Almost the entire coastline of Africa is clearly visible. The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is the Malagasy Republic. The Asian mainland is on the horizon toward the northeast.


The mission was the final in a series of three J-type missions planned for the Apollo Program. These J-type missions can be distinguished from previous G- and H-series missions by extended hardware capability, larger scientific payload capacity and by the use of the battery-powered Lunar Roving Vehicle, or LRV.

The Meaning of the "IMPACT FACTOR" of an academic journal...

Journal Impact Factor is a product of Thomson ISI (Institute for Scientific Information) from Journal Citation Report (JCR)

Journal Citation Report:

JCR provides different quantitative tools to evaluate academic journals and Impact factor is one of those tools. Impact factors are calculated yearly starting from 1975 for those journals that are indexed in the JCR.

"IMPACT FACTOR is a measure of the frequency with which the "average article" in a journal has been cited in a given period of time."

"In a given year, the impact factor of a journal is the average number of citations received per paper published in that journal during the two preceding years."

Example:

The impact factor 2014 for a journal would be calculated as follows: 

A = the number of times articles published in 2012-2013 were cited in indexed journals during 2013

B = the number of articles, reviews, proceedings or notes published in 2012-2013

impact factor 2014 = A/B

(note that the impact factor 2013 will be published in 2014, because it could not be calculated until all of the 2013 publications had been received. Impact factor 2014 will be published in 2015)
