A chemical reaction between iron-containing minerals and water may produce enough hydrogen “food” to sustain microbial communities living in pores and cracks within the enormous volume of rock below the ocean floor and parts of the continents, according to a new study led by the University of Colorado Boulder.
University of Colorado Boulder Assistant Professor Nikolaus Correll likes to think in multiples. If one robot can accomplish a singular task, think how much more could be accomplished if you had hundreds of them.
Correll and his computer science research team recently created a swarm of 20 robots, each the size of a pingpong ball, which they call “droplets.” When the droplets swarm together, Correll said, they form a “liquid that thinks.”
In 1977, Jimmy Carter was sworn in as president, Elvis died, Virginia park ranger Roy Sullivan was hit by lightning a record seventh time and two NASA space probes destined to turn planetary science on its head launched from Florida.
When the space shuttle Atlantis lifted off for its journey to the International Space Station in 2009, it had on board two butterfly habitats, which were part of an experiment conducted by CU-Boulder and K–12 students across the country.
Corn and potato crops may soon provide information to farmers about when the plants need water and how much should be delivered, due to a CU-Boulder invention. A tiny sensor clipped to plant leaves charts their moisture content, a key measure of water deficiency and accompanying stress. Data from the leaves is sent wirelessly over the Internet to computers linked to irrigation equipment, ensuring timely watering, reducing excessive water and energy use, and potentially saving farmers millions of dollars a year.
