Researchers confirm universal principles of phase transitions

November 04, 2016

New research conducted at the University of Chicago has confirmed a decades-old theory describing the dynamics of continuous phase transitions.

The findings, published in the Nov. 4 issue of Science, provide the first clear demonstration of the Kibble-Zurek mechanism for a quantum phase transition in both space and time. Prof. Cheng Chin and his team of UChicago physicists observed the transition in gaseous cesium atoms at temperatures near absolute zero.

Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface.
Warmer temperatures cause decline in key runoff measure
Since the mid-1980s, the percentage of precipitation that becomes streamflow in the Upper Rio Grande watershed has fallen more steeply than at any point in at least 445 years, according to a new study led by NCAR.
Materials bend as they 'breathe' under high temperatures
Researchers develop high-temperature systems based on metal oxides that 'breathe' oxygen in and out, that could be used to control devices inside nuclear reactors or jet engines.

The World Meteorological Organization announced today new verified record high- temperatures in Antarctica, ranging from the high 60s (in Fahrenheit) to the high teens, depending on the location they were recorded in Antarctica.
Northeast US temperatures are decades ahead of global average
Results of a new study by researchers at the Northeast Climate Science Center at the University of Massachusetts Amherst suggest that temperatures across the northeastern United States will increase much faster than the global average, so that the 2 degrees Celsius warming target adopted in the recent Paris Agreement on climate change will be reached about 20 years earlier for this part of the US compared to the world as a whole.

Now Playing: TED Radio Hour

Anthropomorphic
Do animals grieve? Do they have language or consciousness? For a long time, scientists resisted the urge to look for human qualities in animals. This hour, TED speakers explore how that is changing. Guests include biological anthropologist Barbara King, dolphin researcher Denise Herzing, primatologist Frans de Waal, and ecologist Carl Safina.

#SB2 2019 Science Birthday Minisode: Mary Golda Ross
Our second annual Science Birthday is here, and this year we celebrate the wonderful Mary Golda Ross, born 9 August 1908. She died in 2008 at age 99, but left a lasting mark on the science of rocketry and space exploration as an early woman in engineering, and one of the first Native Americans in engineering. Join Rachelle and Bethany for this very special birthday minisode celebrating Mary and her achievements. Thanks to our Patreons who make this show possible! Read more about Mary G.
