PASADENA, Calif. – NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole.
In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph(150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.

New Microsoft-commissioned study also highlights dangers for those that use counterfeit software.
REDMOND, Wash. — Although some computer users may actively seek pirated software in hopes of saving money, the chances of infection by unexpected malware are one in three for consumers and three in 10 for businesses, according to a new study commissioned by Microsoft Corp. and conducted by IDC. As a result of these infections, the research shows that consumers will spend 1.5 billion hours and US$22 billion identifying, repairing and recovering from the impact of malware, while global enterprises will spend US$114 billion to deal with the impact of a malware-induced cyberattack.
The global study analyzed 270 websites and peer-to-peer networks, 108 software downloads, and 155 CDs or DVDs, and it interviewed 2,077 consumers and 258 IT managers or chief information officers in Brazil, China, Germany, India, Mexico, Poland, Russia, Thailand, the United Kingdom and the United States. Researchers found that of counterfeit software that does not come with the computer, 45 percent comes from the Internet, and 78 percent of this software downloaded from websites or peer-to-peer networks included some type of spyware, while 36 percent contained Trojans and adware.

U alum Lesa Nord talks about her Fulbright Scholar experience
Lesa Nord was one of two U students on the Twin Cities campus to receive a highly competitive Fulbright Scholarship this year to the United Kingdom, where she is completing an interdisciplinary degree in humanitarianism and conflict response at the University of Manchester.
Nord began her college education at North Hennepin Community College before transferring to the U and receiving a bachelor of individualized studies with high distinction from the College of Liberal Arts. Along the way she has become a certified Emergency Medical Technician, and she’s already served as a volunteer interpreter and technician on medical mission trips in developing countries.(more…)
Elizabeth Bradley started her career on the faculty at Yale in 1996 and currently serves in a variety of roles at the University, including professor of public health, faculty director for the Global Health Initiative and the Global Health Leadership Institute, and master of Branford College.
Her research focuses on strengthening health systems and has contributed important findings about organizational change and quality of care within the hospital, nursing home, and hospice settings. She has been involved with several international projects including research in China, Ethiopia, Liberia, South Africa, and the United Kingdom.
Bradley spoke recently about her work on campus and around the world, and the many other items on her “to-do” list. (more…)
Microbe-eating flies from at least three different locations around the world recently have evolved into herbivores, feeding on some of the most toxic plants on Earth. Fly detectives and UA evolutionary biologists Noah Whiteman and Richard Lapoint are trying to find out what genetic pathways led the flies to such a major change of lifestyle.
For millennia, they buzzed through the woods, contentedly munching yeasts off the surfaces of leaves, bracken and rotting duff on the forest floor. But now, flies in the family Drosophilidae, whose disparate members dwell in areas all across the planet, have evolved into all-out vegetarians with a wicked diet of plants that are deadly to most other organisms.
What, University of Arizona scientists would like to know, has caused these flies, yeast-feeders for nearly 80 million years, to independently go cold turkey with respect to their formerly meaty diets? (more…)
The International North Greenland Eemian Ice Drilling (NEEM) project results indicate that melting of Antarctic ice sheet may have contributed more to sea level rise than melting of the Greeland ice sheet some 100,000 years ago
A new study that provides surprising details on changes in Earth’s climate from more than 100,000 years ago indicates that the last interglacial–the period between “ice ages”–was warmer than previously thought and may be a good analog for future climate, as greenhouse gases increase in the atmosphere and global temperatures rise.
The research findings also indicate that melting of the massive West Antarctic ice sheet may have contributed more to sea-level rise at that time than melting of the Greenland ice sheet. (more…)
PASADENA, Calif. – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study. These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.
An international research team led by Sassan Saatchi of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., analyzed more than a decade of satellite microwave radar data collected between 2000 and 2009 over Amazonia. The observations included measurements of rainfall from NASA’s Tropical Rainfall Measuring Mission and measurements of the moisture content and structure of the forest canopy (top layer) from the Seawinds scatterometer on NASA’s QuikScat spacecraft.
