Clarksville, TN – Dr. Bob Shelton,associate professor of chemistry, has an idea for an extremely efficient automobile. He’d like to see a vehicle powered by water and sunlight rather than gasoline.
“In some ways, that’s the way plants work,” he said. “That’s what we’re going to try to mimic with our photocatalytic hydrogen producers that mimic the reaction of the oxygen-evolving center in plants.”

Pasadena, CA – A new study tracks the “rain” of charged water particles into the atmosphere of Saturn and finds there is more of it and it falls across larger areas of the planet than previously thought.
The study, whose observations were funded by NASA and whose analysis was led by the University of Leicester, England, reveals that the rain influences the composition and temperature structure of parts of Saturn’s upper atmosphere. The paper appears in this week’s issue of the journal Nature.

Pasadena, CA – A laboratory experiment at NASA’s Jet Propulsion Laboratory, Pasadena, CA, simulating the atmosphere of Saturn’s moon Titan suggests complex organic chemistry that could eventually lead to the building blocks of life extends lower in the atmosphere than previously thought.
The results now point out another region on the moon that could brew up prebiotic materials. The paper was published in Nature Communications this week.
NASA’s Mars rover Curiosity sees evidence that conditions favorable for Microbial Life extends beyond current location
Written by Guy Webster
The Woodlands, TX – NASA’s Mars rover Curiosity has seen evidence of water-bearing minerals in rocks near where it had already found clay minerals inside a drilled rock.
Last week, the rover’s science team announced that analysis of powder from a drilled mudstone rock on Mars indicates past environmental conditions that were favorable for microbial life. Additional findings presented March 18th at a news briefing at the Lunar and Planetary Science Conference in The Woodlands, Texas, suggest those conditions extended beyond the site of the drilling.

Washington, D.C. – An analysis of a rock sample recently collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes.
“A fundamental question for this mission is whether Mars could have supported a habitable environment,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program at the agency’s headquarters in Washington. “From what we know now, the answer is yes.”

Washington, D.C. – Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the sun for a closer look.
The discovery was made by a group of astronomers trying to solve a decades-old mystery: What heats and accelerates the solar wind?
APSU Provost Lecture Series to have Biology professor Dr. Sergei Markov to discuss algae for practical purposes
Clarksville, TN – Anbiology professor, who has gained international recognition with his research in the last few years, will be the next presenter of the Provost Lecture Series at APSU.
Dr. Sergei Markov, associate professor of biology, will present at 3:00pm, Thursday, March 7th in the Morgan University Center, Room 303. All sessions of the Provost Lecture Series are free and open to the public.
The title of his presentation is “Growing algae in photobioreactors for practical purposes.” «Read the rest of this article»

Pasadena, CA – A star thought to have passed the age at which it can form planets may, in fact, be creating new worlds. The disk of material surrounding the surprising star called TW Hydrae may be massive enough to make even more planets than we have in our own solar system.
The findings were made using the European Space Agency’s Herschel Space Telescope, a mission in which NASA is a participant.
At roughly 10 million years old and 176 light years away, TW Hydrae is relatively close to Earth by astronomical standards. Its planet-forming disk has been well studied. TW Hydrae is relatively young but, in theory, it is past the age at which giant planets already may have formed.

Greenbelt, MD – Nearly 200,000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy.
Vast clouds of gas within it slowly collapse to form new stars. In turn, these light up the gas clouds in a riot of colors, visible in this image from the NASA/ESA Hubble Space Telescope.

Pasadena, CA – Titan’s siblings must be jealous. While most of Saturn’s moons display their ancient faces pockmarked by thousands of craters, Titan – Saturn’s largest moon – may look much younger than it really is because its craters are getting erased.
Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters, according to new research using observations from NASA’s Cassini spacecraft.
