Kennedy Space Center, FL – The six astronauts currently living on the International Space Station (ISS) have become the first people to eat food grown in space. The fresh red romaine lettuce that accompanied the crew’s usual freeze-dried fare, however, is far from the first crop grown on a space station.
For decades, NASA and other agencies have experimented with plants in space, but the results were always sent to Earth for examination, rather than eaten.
A number of technologies NASA has explored for these space-farming experiments also have returned to Earth over the years and found their way onto the market.

Pasadena, CA – Science is full of serendipity — moments when discoveries happen by chance or accident while researchers are looking for something else. For example, penicillin was identified when a blue-green mold grew on a Petri dish that had been left open by mistake.
Now, satellite instruments have given climate researchers at NASA and other research institutions an unexpected global view from space of a nearly invisible fluorescent glow that sheds new light on the productivity of vegetation on land.

Pasadena, CA – Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet’s living kingdoms. How did it all begin?
A new study from researchers at NASA’s Jet Propulsion Laboratory in Pasadena, CA, and the Icy Worlds team at NASA’s Astrobiology Institute, based at NASA’s Ames Research Center in Moffett Field, CA, describes how electrical energy naturally produced at the sea floor might have given rise to life.
Tennessee Department of Health says managing exposure to Asthma “Triggers” can prevent or reduce Attacks
Nashville, TN – Asthma: if you don’t have it, you probably know someone who does. In Tennessee, approximately six percent of adults and nine percent of children have asthma. The chronic disease that narrows and inflames airways of the lungs can quickly cause breathing to become difficult.
While many people find relief with small inhaler devices, the Tennessee Department of Health recommends increased awareness about “triggers” to reduce onset of attacks. «Read the rest of this article»

Removal of mold reduces health risks and property damage
The flood waters in Tennessee are receding, but another problem may be rising. After natural disasters such as floods and tornadoes, excess moisture and standing water contribute to the growth of mold in homes and other buildings.
In just 24-48 hours of water exposure, surfaces and materials can become contaminated with mold. Saturated walls, soggy furniture and soppy carpet are the perfect environment for the development of mold and mildew, which can lead to health hazards. «Read the rest of this article»
