CU study provides new evidence ancient asteroid caused global firestorm on Earth

A new look at conditions after a Manhattan-sized asteroid slammed into a region of Mexico in the dinosaur days indicates the event could have triggered a global firestorm that would have burned every twig, bush and tree on Earth and led to the extinction of 80 percent of all Earth’s species, says a new University of Colorado Boulder study.

Led by Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences, or CIRES, the team used models that show the collision would have vaporized huge amounts of rock that were then blown high above Earth’s atmosphere. The re-entering ejected material would have heated the upper atmosphere enough to glow red for several hours at roughly 2,700 degrees Fahrenheit — about the temperature of an oven broiler element — killing every living thing not sheltered underground or underwater.

Under California: An ancient tectonic plate

The Isabella anomaly — indications of a large mass of cool, dehydrated material about 100 kilometers beneath central California — is in fact a surviving slab of the Farallon oceanic plate. Most of the Farallon plate was driven deep into the Earth’s mantle as the Pacific and North American plates began converging about 100 million years ago, eventually coming together to form the San Andreas fault.

PROVIDENCE, R.I. [Brown University] — Large chunks of an ancient tectonic plate that slid under North America millions of years ago are still present under parts of central California and Mexico, according to new research led by Brown University geophysicists. (more…)

Software Piracy Costs Billions in Time, Money for Consumers and Businesses

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.

New study challenges theory of upward mobility in developing nations

Although immigration to the United States from Latin American countries, particularly Mexico, has captured much public attention, immigrants who move between countries in Latin America have more difficulty than those moving to the United States.

Donald Bogue, professor emeritus in sociology and a distinguished scholar of demography, has found that unlike immigrants to the United States, immigrants between nations in Latin America frequently do not improve their lives by moving. (more…)

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…)

Automated trail cameras set up by a UA research team have snapped pictures of a male jaguar and a male ocelot roaming the rugged Southern Arizona landscape.

An adult male jaguar and an adult male ocelot have been photographed in two separate Southern Arizona mountain ranges by automated wildlife monitoring cameras. The images were collected as part of the Jaguar Survey and Monitoring Project led by the University of Arizona. Both animals appear to be in good health.

In late November, the UA project team downloaded photos from wildlife cameras set up as part of the research project and found new pictures of a jaguar in the Santa Rita Mountains. A total of 10 jaguar photos were taken by three UA cameras and one Arizona Game and Fish Department camera. The cat’s unique spot pattern matched that of a male jaguar photographed by a hunter in the Whetstone Mountains in the fall of 2011, providing clear evidence that the big cats travel between Southern Arizona’s “sky island” mountain ranges.

Lecturer explores the imperatives of environmental ethics

Speaking to University of Delaware faculty and students and community members in Brown Lab on Monday night, Oct. 15, environmental philosopher Kathleen Dean Moore discussed how important it is for humans to realize their ethical responsibility to save the world from a climate crisis.

In a lecture titled “Why It’s Wrong to Wreck the World: Climate Change and the Moral Obligation to the Future,” Moore reflected on the relationship humans have with the environment and argued that once humans realize the impact of their actions, they will naturally feel a moral obligation to care for the planet.
