When praying mantises, dragonflies, ants and other insects peer out at the world, their bulging, compound eyes allow them to see an incredibly wide field of view with an almost infinite depth of field.
Imitating the functionality of an insect eye — which is really a collection of many tinier eyes, known as ommatidia — in a camera has been a long sought-after goal for engineers. Now, camera lenses with wide fields of view, such as fisheye lenses, create distortion around the edges of the image.
To find the answer, he went about building experiments. He tried to test the impact of the fields on E. coli, on cancer cells, on fruit flies and even on mice. But he quickly ran into a problem: The magnetic fields in the biological incubators he was using weren’t consistent. In fact, they weren’t even close.
It took at least 1,000 hours of work but the result is stunning.
During the 2011-12 academic year, engineering students in Andrews Hall started an extracurricular project to build a “grand orrery,” a mechanical planetary system that illustrates the relative positions and motions of both the inner and outer planets.
A frigid brine, isolated from the outside world for about three millennia underneath a thick layer of ice in an Antarctic lake, harbors life, according to a research team that includes scientists from the University of Colorado Boulder.
The finding, published in the Proceedings of the National Academy of Sciences, offers a hint to how life might be able to thrive in extreme, icy conditions elsewhere in our solar system, such as those found on Saturn’s moon Enceladus, Jupiter’s moon Europa or on Mars.
The wild and dramatic cascade of ice into the ocean from Alaska’s Columbia Glacier, an iconic glacier featured in the documentary “Chasing Ice” and one of the fastest moving glaciers in the world, will cease around 2020, according to a study by the University of Colorado Boulder.
STEM education at CU-Boulder is having a ripple effect, transforming undergraduate and graduate-level classrooms; boosting the number of STEM majors pursuing teaching careers; and fanning out to improve STEM learning at K-12 levels. CU gathers to celebrate STEM scholarship and education projects this Oct. 1 at the 4th Annual Symposium on STEM Education.
One CU-Boulder professor’s idea of how to help students learn more grew into such a successful program that it is now a model for schools throughout the nation.
Through the Colorado Learning Assistant Program, more than 1,500 learning assistant positions have been filled at CU-Boulder, helping to improve introductory courses in 10 departments and to positively impact more than 10,000 CU students each year.
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.
