Mexican Culture's Endangered Whistle Speech Documented by UA's David Yetman
One of the jewels of the UA's Southwest Center is a documentary on the whistled speech of the Chinantecan people of Oaxaca, Mexico, who rely on the lifts and depressions of whistling to communicate across great distances. UA researcher David Yetman, who has devoted his career to studying and documenting the cultures of the Americas, collaborated to document the whistled speech of the last Chinantec whistlers.
To celebrate its first century, the UA department of electrical and computer engineering has organized a program of events to demonstrate how engineering affects every aspect of our lives. Highlights include an exhibition of planetary exploration rovers, a public lecture series and a gala.
UA archaeologist Vance T. Holliday, writing with a colleague in Current Anthropology, finds no evidence to support the theory that a catastrophic comet impact 13,000 years ago led to the sudden demise of Clovis hunters in North America.
Collections of new small molecules with the potential to become important in the creation of new medications are under development by three UA researchers thanks to a $1.1 million three-year grant from the National Institutes of Health.
All but overlooked until the past decade, marine viruses far outnumber any other biological entity on the planet. Scientists are only beginning to discover the invisible particles that are the cogs of Earth's system, changing dynamics in food webs, fisheries, even climate.
UA physicists have discovered a new way of harvesting waste heat and turning it into electrical power. Taking advantage of quantum effects, the technology holds great promise for making cars, power plants, factories and solar panels more efficient.
