Washington, Mar 25 : NASA's Curiosity rover found nitrogen on Mars' surface from release during heating of Martian sediments, by using the Sample Analysis at Mars (SAM) instrument.
The nitrogen was detected in the form of nitric oxide, and could be released from the breakdown of nitrates during heating. Nitrates are a class of molecules that contain nitrogen in a form that can be used by living organisms. The discovery adds to the evidence that ancient Mars was habitable for life.
Nitrogen has been essential for all known forms of life, since it's used in the building blocks of larger molecules like DNA and RNA, whichencode the genetic instructions for life, and proteins, which are used to build structures like hair and nails, and to speed up or regulate chemical reactions.

Washington, March 25 : When we look at a new word, out brain first learns the word and then sees it like a picture, instead of a group of letters.
The finding from Georgetown University Medical Center (GUMC) shows that the brain learns words quickly by tuning neurons to respond to a complete word, not parts of it.
Study's senior author, Maximilian Riesenhuber, PhD said that the neurons respond differently to real words, such as turf, than to nonsense words, such as turt, showing that a small area of the brain is "holistically tuned" to recognize complete words.
Neurons in a small brain area remember how the whole word looks, using what could be called a visual dictionary, he added.

Washington, Mar 24 : A new study has provided a deeper insight into how Maya civilization's mobile, hunter- gatherer lifestyle turned into a sedentary way of life.
Led by University of Arizona archaeologists Takeshi Inomata and Daniela Triadan, the team's excavations of the ancient Maya lowlands site of Ceibal suggest that as the society transitioned from a heavy reliance on foraging to farming, mobile communities and settled groups co-existed and may have come together to collaborate on construction projects and participate in public ceremonies.
A public plaza uncovered at Ceibal dates to about 950 B. C., with surrounding ceremonial buildings growing to monumental sizes by about 800 B. C. Yet, evidence of permanent residential dwellings in the area during that time is scarce.

Washington, Mar 24 : A new study has revealed that Jupiter may have destroyed Solar System's first generation of Earth-like planets.
Long before Mercury, Venus, Earth, and Mars formed, it seemed that the inner solar system may have harbored a number of super-Earths planets larger than Earth but smaller than Neptune. If so, those planets are long gone, broken up and fallen into the sun billions of years ago largely due to a great inward-and-then-outward journey that Jupiter made early in the solar system's history.
