Dear Friends,

I hope you enjoy this inaugural newsletter from the School of Physical Sciences at UC Irvine! I am honored to have been appointed to serve asDean of this dynamic and diverse group of scientists, educators, students, and staff.   As a Professor of Chemistry at UC Irvine since 1992, I have had many opportunities to observe the great work going on in our School and watch the national and international recognition of our work increase every year.

 

Since it was established in 1965, the School of Physical Sciences has advanced to the top echelon ofacademia in a remarkably short time.   In a recent assessment of research-doctorate programs conducted by the National Research Council, each of our four departments was ranked at or above the 15th percentile - rare across-the-board excellence.  

 

If you'll take a moment to explore this newsletter, you'll see examples of the remarkable accomplishments of our researchers, who also embrace the teaching mission of a publicuniversity.   Our faculty are not only leading the world in addressing today's problems - we're simultaneously teaching the scientists who will be solving tomorrow's problems. Perhaps more than in any other School, teaching and research are closely linked in the School of Physical Sciences, at both the graduate and undergraduate levels. With few exceptions, each of our faculty members teaches a freshman or sophomore level class each year, as well as welcoming students into his or her research group.

 

Teaching the science curriculum is always a challenge, especially laboratory classes that require specialized equipment. During this time of financial difficulty, I am directing all contributions from alumni toward either undergraduate laboratory renovation or summer research fellowships for undergraduate and graduate research students. If you are kind enough to make a contribution, please feel free to specify which category and/or to which Department your gift should bedirected.

 

I hope you will take advantage of upcoming opportunities to get involved with our School - especially next week's presentation in our quarterly Breakfast Lecture Series , and experience firsthand the global impact of our scientists.

 

I thank you for your continued interest in our School, and we look forward to seeing you on campus soon.      

      

Sincerely,

 

Kenneth C. Janda

Our world orbits a sun located on one of the arms of

Milky Way

the Milky Way, a galaxy of some 200 billion stars with spiral limbs that whirl around a thin disk.   But how did the galaxy develop those famous arms?

A new theory says they formed after the Milky Way waswhacked by a dwarf galaxy, sending cascades of stars flying to the galactic rim.  And the collision has happened not just once, but twice in the last twobillion years -- and a third smashup is in the cards within the next 10 million years, a blink of an eye in cosmic terms, say a team of astronomers.  The intruder is named the Sagittarius Dwarf Elliptical Galaxy...   Read more .

Q & A: The Quest of the Earth System Scientist   By Felicity Barringer, The New York Times

Ralph Cicerone

Ralph J. Cicerone , president of the National Academy of Sciences, wasback in his old haunt in September, celebrating the 20th anniversary of the University of California, Irvine's Department of Earth System Science , which he founded. He later served as the university's chancellor. Dr. Cicerone spoke with The New York Times about scientific research on the campus, the national attitude toward science today and the scientific questions he would most like to see answered. Following are excerpts, edited for brevity and clarity.

Q.
You're back here to celebrate the Department of Earth System Science's 20th anniversary; what has the department accomplished over those two decades?

A.
Both on the side of research as well as classroom instruction, I think they are doing very well. The quality of graduates who are coming here, the places they are turning down in order to come to Irvine, reflects on that.

Tracking the Movement of Ice Across Antarctica

By Sindya N. Bhanoo,  The New York Times

 

Antartica

A new map of Antarctica illustrates for the first time how ice moves across the continent. The map's creators believe it may be a crucial tool in helping researchers understand how a warming climate is changing the continent. The creation of the digital map was supported by NASA and combines data gathered from 2007 to 2009 by satellites belonging to the Canadian Space Agency, the European Space Agency and the Japan Aerospace Exploration Agency. "It's a unique collaboration with each satellite contributing different skillsand mapping different parts of the continent," said Eric Rignot, an Earth system scientist at the University of California, Irvine, and the study's lead author.  Read more .

Bacteria Responsible for Missing 'Atmospheric Brooms' That Sweep the SkyClean?   By James Mitchell Crow, RSC: Advancing the Chemical Sciences 

Atmospheric Brooms
Soil bacteria produce chemicals that help to cleanse the atmosphere  

Hydroxyl radicals play a central role in cleaning pollutants from our atmosphere - but the ultimate source of Earth's 'atmospheric brooms' has provendifficult to track down. An international team of researchers have now found that the answer could lie not in the air above us, but in the ground beneath our feet. Previous research has established that up to one third of the hydroxyl radicals formed in the lower atmosphere come from the photochemical breakdown of nitrous acid (HONO). But here the trail ran cold, the source of much of this HONO unknown.Read more .

New Theories Over Methane Puzzle   

By Matt McGrath, BBC News

Methane Theories

have come up with two widely differing theories as to thecause. One suggests the decline was caused by greater commercial use of natural gas, the other that increased use in Asia of artificial fertilizer was responsible. Both studies agree that human activities are the key element. And there are suggestions that methane levels are now on the rise again. Methane is regarded as one of the most potent greenhouse gases, trappingover 20 times more atmospheric heat than carbon dioxide... Read more.

Fire and ice don't mix. Neither do oil and water - or so the sayings go. But if you're an ace UC Irvine undergraduate like Joel Rivera working with Kenneth C. Janda, dean ofthe School of Physical Sciences, barriers are broken in more ways than one. Janda, a lifelong chemist with a laboratory two floors up from his Rowland Hall dean's office, says Rivera came to his attention nearly four yearsago. Kika Friend, director of UCI's California Alliance for Minority Participation program - which supports students in science, technology, engineering and math - told him about the talented freshman. "We hit it off as soon as we met," Janda recalls. "We both do chemistry for fun; it's our hobby as well as our job." Translation: Both thought it would be a great idea tofigure out how to load as much propane as fast as possible into ice and then burn it. In scientific terms, they're studying the kinetics of the formation of gas clathrate hydrates - compounds made when water molecules bond to form cages around gaseous molecules. The work has huge potential. There are a trillion tons of methane stored in deposits under the world's oceans,... Read more .
