The breeding population of chinstrap penguins has declined significantly as temperatures have rapidly warmed on the Antarctic Peninsula, according to researchers funded in part by the National Science Foundation (NSF).
The study indicates that changing climatic conditions, rather than the impact of tourism, have had the greatest effect on the chinstrap population.
Ron Naveen, founder of a nonprofit science and conservation organization, Oceanites, Inc., of Chevy Chase, Md., documented the decline in a paper published in the journal Polar Biology. Naveen and coauthor Heather Lynch, of Stony Brook University, are researchers with the Antarctic Site Inventory (ASI). (more…)
Doctoral student studies energy poverty in Ghana, Africa
In the United States, electricity is a creature comfort many citizens take for granted. Yet for more than a billion people across the globe, particularly in developing regions, electrification is the exception, not the norm.
Sub-Saharan Africa, for example, is the least electrified region in the world. It has the lowest generation capacity behind eastern South Asia and few programs that provide access to modern forms of energy. (more…)
The gut bacteria of honey bees have acquired several genes that confer resistance to tetracycline, a direct result of more than five decades of use of antibiotics by American beekeepers and a potential health hazard for bee colonies, a new study by Yale University researchers show.
The genetic analysis of the gut bacteria, which are believed to help in bees’ digestion and ability to ward off parasites, suggests changing antibiotic use by beekeepers might be one factor in the mysterious colony collapse disorder afflicting bee populations. (more…)
Jack Turner, UW assistant professor of political science, is the author of “Awakening to Race: Individualism and Social Consciousness in America,” published this month by University of Chicago Press. He answered a few questions about his book for UW Today.
What’s the central concept behind “Awakening to Race”?
The book addresses the challenge of racial justice by asking, “What does it mean to be a self-aware human being? What does it mean to be awake to reality?”
In part, it means confronting the worst aspects of ourselves and our lives. Being awake to reality in the United States means confronting the ways America’s history of slavery, Jim Crow and white supremacy still shapes the present — the opportunities we have or we lack, the confidence we have in ourselves or fail to have in others, the ways our chances for success are still color coded.

UCLA scholar, culinary historian champions foraged foods in new book
Today, delicacies like capers, arugula and fennel are at home at Dean & Deluca, Whole Foods and fancy restaurants, but they haven’t always lived the high life.
These and other darlings of the foodie set started out as peasants’ fodder, foraged from rocky outcroppings, empty fields and roadsides, according to a new book by a UCLA professor.
Luigi Ballerini revisits this distant past in “A Feast of Weeds: A Literary Guide to Foraging and Cooking Wild Edible Plants” (University of California Press), which celebrates the foraged foods that are currently enjoying a renaissance in Italy and elsewhere. (more…)
President Obama designated October as National Cyber Security Awareness Month. We asked John E. Savage, the An Wang Professor of Computer Science, to share his views on what can and should be done to ensure cybersecurity at the national level. Savage is active in cybersecurity from both a policy and technology point of view, having spent the 2009-10 academic year in the U.S. Department of State as a Jefferson Science Fellow.
In a major policy speech delivered last week, Secretary of Defense Leon Panetta sparked a new discussion of cyberwarfare threats, warning that cyberattacks “could virtually paralyze the nation.” The three-part response Panetta outlined emphasizes new cyberwarfare capabilities in the Department of Defense, new policies and organizations across the federal government, and stronger partnerships between the government and international partners and domestic industry.

Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.
These higher-quality images could allow breast tumors to be detected earlier and with much greater accuracy. One in eight women in the United States will be diagnosed with breast cancer during her lifetime.
The research is published the week of Oct. 22 in the early edition of the journal Proceedings of the National Academy of Sciences. (more…)
There’s an old adage (with several variations) that California has four seasons: earthquake, fire, flood and drought. While Californians happily cede the title of Hurricane Capital of America to U.S. East and Gulf coasters, every once in a while, Mother Nature sends a reminder to Southern Californians that they are not completely immune to the whims of tropical cyclones. Typically, this takes the form of rainfall from the remnants of a tropical cyclone in the eastern Pacific, as happened recently when the remnants of Hurricane John brought rain and thunderstorms to parts of Southern California. But could a hurricane ever make landfall in Southern California?
The answer, as it turns out, is yes, and no. While there has never been a documented case of a hurricane making landfall in California, the Golden State has had its share of run-ins and close calls with tropical cyclones. In fact, California has been affected by at least a few tropical cyclones in every decade since 1900. Over that timeframe, three of those storms brought gale-force winds to California: an unnamed California tropical storm in 1939, Kathleen in 1976 and Nora in 1997. But the primary threat from California tropical cyclones isn’t winds or storm surge. It’s rainfall — sometimes torrential — which has led to flooding, damage and, occasionally, casualties. (more…)
