The Rio Grande Rift, a thinning and stretching of Earth’s surface that extends from Colorado’s central Rocky Mountains to Mexico, is not dead but geologically alive and active, according to a new study involving scientists from the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences.

“We don’t expect to see a lot of earthquakes, or big ones, but we will have some earthquakes,” said CU-Boulder geological sciences Professor Anne Sheehan, also a fellow at CIRES. The study also involved collaborators from the University of New Mexico, New Mexico Tech, Utah State University and the Boulder-headquartered UNAVCO. The Rio Grande Rift follows the path of the Rio Grande River from central Colorado roughly to El Paso before turning southeast toward the Gulf of Mexico. (more…)

Yale’s acquisition of a powerful new transmission electron microscope (TEM) is expected to transform researchers’ ability to examine and manipulate atom-scale materials and devices on campus.

The approximately $2 million, state-of-the-art microscope offers atomic resolution for both physical structure and chemical composition, as well as significantly faster processing times than other devices on campus. It is the first unit of this specific TEM model acquired for university laboratory use. (more…)

NASA’s Kepler Mission Finds Three Smallest Exoplanets

PASADENA, Calif. – Astronomers using data from NASA’s Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars.

All three planets are thought to be rocky like Earth but orbit close to their star, making them too hot to be in the habitable zone, which is the region where liquid water could exist. Of the more than 700 planets confirmed to orbit other stars, called exoplanets, only a handful are known to be rocky. (more…)

Berkeley Researchers Provide Detailed Look at Proteasome’s Regulatory Particle

Important new information on one of the most critical protein machines in living cells has been reported by a team of researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. The researchers have provided the most detailed look ever at the “regulatory particle” used by the protein machines known as proteasomes to identify and degrade proteins that have been marked for destruction. The activities controlled by this regulatory particle are critical to the quality control of cellular proteins, as well as a broad range of vital biochemical processes, including transcription, DNA repair and the immune defense system.

Timely Ends: Telomere Length in Early Life Predicts Lifespan

New research by a team from the Universities of Glasgow and Exeter shows that a good indicator of how long individuals will live can be obtained from early in life using the length of specialised pieces of DNA called telomeres.

Telomeres occur at the ends of the chromosomes, which contain our genetic code.

They function a bit like the plastic caps at the end of shoelaces by marking the chromosome ends and protecting them from various process that gradually cause the ends to be worn away. This method of DNA protection is the same for most animals and plants, including humans, and the eventual loss of the telomere cap is known to cause cells to malfunction. This study is the first in which telomere length has been measured repeatedly from early in life of an individual and then for the rest of their natural lives. The results show that telomere length in early life is strongly predictive of lifespan. (more…)
