ANN ARBOR— A dollop of hair gel might not look like much, but Michigan Engineering researchers have found that it’s a labyrinth of chambers and domes, constructed by the particles inside. These structures allow the gel to hold its shape and determine how much pressure it can withstand before it starts to flow.
While manufacturers currently use trial and error to develop gels with a particular degree of solidity, this discovery could provide a way to design gels for particular applications. (more…)
UD alumnus one of Popular Science magazine’s ‘Brilliant 10’ Young Scientists
University of Delaware alumnus Deva Ramanan has been named one of Popular Science magazine’s “Brilliant 10” Young Scientists.
The designation places Ramanan on the magazine’s annual “honor roll” of the 10 most promising scientist for 2012.
Ramanan, who earned his bachelor’s degree in computer engineering at UD in 2000, is an associate professor of computer science at the University of California Irvine (UCI). There he is working to improve a computer’s image recognition capability, or in simpler terms, a computer’s ability to “see people.” (more…)
EAST LANSING, Mich. — Research by Michigan State University astronomers has scientists re-thinking the fates of black holes, particularly in groups of stars known as globular clusters.(more…)
Workshop helps to define the human right to benefit from science
Conscience. Expression. Property. Fair trial. Peaceful assembly. And science?
Yes, says the University of Delaware’s Tom Powers, the international community has declared that there is an inalienable human right to science.
In 1948, the United Nations adopted the Universal Declaration of Human Rights, which guarantees in Article 27 “the right freely to participate in the cultural life of the community, to enjoy the arts and to share in scientific advancement and its benefits.”
The same right was reaffirmed by the U.N. General Assembly in Article 15 of the International Covenant on Economic, Social and Cultural Rights in 1966. (more…)
A dying star is refusing to go quietly into the night, as seen in this combined infrared and ultraviolet view from NASA’s Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX), which NASA has lent to the California Institute of Technology in Pasadena. In death, the star’s dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by the hot stellar core.
This object, called the Helix nebula, lies 650 light-years away in the constellation of Aquarius. Also known by the catalog number NGC 7293, it is a typical example of a class of objects called planetary nebulae. Discovered in the 18th century, these cosmic works of art were erroneously named for their resemblance to gas-giant planets. (more…)
Discovery crucial to revealing fabric of space and time around black hole
UCLA astronomers report the discovery of a remarkable star that orbits the enormous black hole at the center of our Milky Way galaxy in a blistering 11-and-a-half years — the shortest known orbit of any star near this black hole.(more…)
A new species of plant-eating dinosaur with tiny, 1-inch-long jaws has come to light in South African rocks dating to the early dinosaur era, some 200 million years ago.
This “punk-sized” herbivore is one of a menagerie of bizarre, tiny, fanged plant-eaters called heterodontosaurs, or “different toothed reptiles,” which were among the first dinosaurs to spread across the planet. (more…)
A current focus in global health research is to make medical tests that are not just cheap, but virtually free. One such strategy is to start with paper – one of humanity’s oldest technologies – and build a device like a home-based pregnancy test that might work for malaria, diabetes or other diseases.
A University of Washington bioengineer recently developed a way to make regular paper stick to medically interesting molecules. The work produced a chemical trick to make paper-based diagnostics using plain paper, the kind found at office supply stores around the world. (more…)
