PASADENA, Calif. — Astronomers have found a new cosmic source for the same kind of water that appeared on Earth billions of years ago and created the oceans. The findings may help explain how Earth’s surface ended up covered in water. (more…)
Brian P. Schmidt, who graduated from the UA in 1989 with a double major in astronomy and physics, shares this year’s Nobel Prize in Physics with two colleagues for a discovery that has rocked our understanding of the cosmos: The universe is expanding at an ever-faster pace.
In the last years of the 20th century, two teams of researchers set out to race each other to measure the rate of the universe’s expansion, and by extension, unveil how the universe most likely will end. (more…)
Cell-penetrating peptides, such as the HIV TAT peptide, are able to enter cells using a number of mechanisms, from direct entry to endocytosis, a process by which cells internalize molecules by engulfing them.
Further, these cell-penetrating peptides, or CPPs, can facilitate the cellular transfer of various molecular cargoes, from small chemical molecules to nano-sized particles and large fragments of DNA. Because of this ability, CPPs hold great potential as in vitro and in vivo delivery vehicles for use in research and for the targeted delivery of therapeutics to individual cells. (more…)
Some of the world’s most renowned scholars, in fields as diverse as astrophysics, philosophy, and religious studies, will convene on the Yale campus October 6-9 to ponder the most fundamental existential question of all: “Why Is There Anything in the Universe?” (more…)
EAST LANSING, Mich. — People who think they can learn from their mistakes have a different brain reaction to errors than those who don’t think they can learn from their mistakes, according to a groundbreaking study by Michigan State University researchers. (more…)
BERKELEY, CA — Saul Perlmutter, an astrophysicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and a professor of physics at the University of California at Berkeley, has won the 2011 Nobel Prize in Physics “for the discovery of the accelerating expansion of the universe through observations of distant supernovae.” Perlmutter heads the international Supernova Cosmology Project, which pioneered the methods used to discover the accelerating expansion of the universe, and he has been a leader in studies to determine the nature of dark energy.

ANN ARBOR, Mich.— The solar wind sandblasts the surface of planet Mercury at its poles, according to new data from a University of Michigan instrument on board NASA’s MESSENGER spacecraft.
The sodium and oxygen particles the blistering solar wind kicks up are the primary components of Mercury’s wispy atmosphere, or “exosphere,” the new findings assert. Through interacting with the solar wind, they become charged in a mechanism that’s similar to the one that generates the Aurora Borealis on Earth. (more…)
Small bypass vessels which act as a ‘back-up system’ for the heart’s main arteries play a significant role in reducing the mortality of patients with coronary artery disease, according to new research. (more…)
