Spear Phishing: Researchers Work to Counter Email Attacks that Gain Recipients’ Trust

The email resembled the organization’s own employee e-newsletter and asked recipients to visit a website to confirm that they wanted to continue receiving the newsletter. Another email carried an attachment that said it contained the marketing plan the recipient had requested at a recent conference. A third email bearing a colleague’s name suggested a useful website to visit.

None of these emails were what they pretended to be. The first directed victims to a website that asked for personal information, including the user’s password. The second included a virus that launched when the “marketing plan” was opened. The third directed users to a website that attempted to install a malicious program. (more…)

Monitoring Hurricanes: Georgia Tech Engineers Assist NASA with Instrument for Remotely Measuring Storm Intensity

A device designed by engineers at the Georgia Tech Research Institute (GTRI) is part of the Hurricane Imaging Radiometer (HIRAD), an experimental airborne system developed by the Earth Science Office at the NASA Marshall Space Flight Center in Alabama.

Known as an analog beam-former, the GTRI device is part of the radiometer, which is being tested by NASA on a Global Hawk unmanned aerial vehicle. The radiometer measures microwave radiation emitted by the sea foam that is produced when high winds blow across ocean waves. By measuring the electromagnetic radiation, scientists can remotely assess surface wind speeds at multiple locations within the hurricanes. (more…)

Teaching Autistic Teens to Cope

Unique UCLA program that teaches social skills proves effective over long term

Teenagers with autism spectrum disorder are in a bind. The disorder is characterized by impairments in communication and social interaction, but it’s a continuum, so some teens diagnosed with ASD are considered high functioning and healthy enough to be “mainstreamed” in school.

But without the proper social skills, even mainstreamed teens don’t quite fit into the general social milieu of middle school or high school. As a result, they suffer from all the slings and arrows of that world.

Since 2006, however, the UCLA PEERS (Program for the Education and Enrichment of Relational Skills) clinic has assisted high-functioning teens with ASD by literally teaching them the strategies they need to fit in better with their peers. And while previous research demonstrated that the program was effective, it wasn’t known whether the new skills “stuck” with these teens after they completed the PEERS classes. (more…)

A New Way of Looking at Photosystem II

Berkeley Lab and SLAC Researchers Study Key Protein Complex Crucial to Photosynthesis

Future prospects for clean, green, renewable energy may hinge upon our ability to mimic and improve upon photosynthesis – the process by which green plants, algae and some bacteria convert solar energy into electrochemical energy. An artificial version of photosynthesis, for example, could use sunlight to produce liquid fuels from nothing more than carbon dioxide and water. First, however, scientists need a better understanding of how a large complex of proteins, called photosystem II, is able to split water molecules into oxygen, electrons and hydrogen ions (protons). A new road to reaching this understanding has now been opened by an international team of researchers, led by scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and SLAC National Accelerator Laboratory.

Using ultrafast, intensely bright pulses of X-rays from SLAC’s Linac Coherent Light Source (LCLS), the research team produced the first ever images at room temperature of microcrystals of the photosystem II complex. Previous imaging studies, using X-rays generated via synchrotron radiation sources, required cryogenic freezing, which alters the samples. Also, to catalyze its reactions, photosystem II relies upon an enzyme that contains a manganese-calcium cluster that is highly sensitive to radiation. With the high-intensity femtosecond X-ray pulses of the LCLS, the research team was able to record intact images of these clusters before the radiation destroyed them. (more…)

Playing the Odds to Your Favor

UA student Jason Xu has been recognized by the College of Science for his undergraduate research.

Wuhan, China and Tucson, Ariz.: These cities are thousands of miles apart, but they have one commonality – University of Arizona student Jason Xu.

A Chinese native and mathematics senior in the Honors College, Xu was selected as the recipient of this year’s Excellence in Undergraduate Research award by the UA College of Science at its Galileo Circle reception event.

The award “is a huge honor and means a lot to me. I feel really good to be representing the math department,” Xu said. (more…)

Global Health: Students Build Wiki of Medical Devices Designed for Low-Income Countries

ANN ARBOR, Mich.— In parts of the world without reliable electricity, a pedal-powered nebulizer could provide life-saving asthma treatments. Small wax-filled sleeping bags could keep premature infants warm. A salad spinner centrifuge for blood samples could help clinicians diagnose anemia.

University of Michigan researchers have cataloged more than 100 such technologies in a new wiki of medical devices designed for resource-limited settings. The Global Health Medical Device Compendium, an open-source inventory, is hosted by the popular appropriate technology wiki Appropedia. It is expected to serve as an important communication vehicle for end users, non-governmental organizations, researchers and others to help advance such technologies. (more…)

Countries That Best Prepare Math Teachers Share Similarities

EAST LANSING, Mich. — Countries that best prepare math teachers meet several key conditions generally lacking in the United States, according to the first international study of what teacher preparation programs are able to accomplish.

The study, led by Michigan State University, suggests that in countries such as Taiwan and Singapore, future math teachers are better prepared because the students get rigorous math instruction in high school; university teacher-preparation programs are highly selective and demanding; and the teaching profession is attractive, with excellent pay, benefits and job security.

Science Outreach : Getting Started is Easy!

Sharing scientific knowledge is a fundamental part of university life. Regardless of whether you’re an undergraduate or a tenured professor, everyone has the responsibility of spreading their knowledge as widely as possible.

Why would you want to, though? “For a variety of reasons,” answers William Raillant-Clark, Press attaché at Université de Montréal’s Office of Communications and Public Relations. “The media is an excellent vehicle for communicating your ideas or your discoveries to the general public, and it can also draw the attention of your research peers to your work. This is one of the reasons why funding partners and potential research directors take into consideration science outreach work.” (more…)
