Emerging Consensus Shows Climate Change Already Having Major Effects on Ecosystems and Species

Plant and animal species are shifting their geographic ranges and the timing of their life events – such as flowering, laying eggs or migrating – at faster rates than researchers documented just a few years ago, according to a technical report on biodiversity and ecosystems used as scientific input for the 2013 Third National Climate Assessment.

The report, Impacts of Climate Change on Biodiversity, Ecosystems, and Ecosystem Services, synthesizes the scientific understanding of the way climate change is affecting ecosystems, ecosystem services and the diversity of species, as well as what strategies might be used by natural resource practitioners to decrease current and future risks. More than 60 federal, academic and other scientists, including the lead authors from the U.S. Geological Survey, the National Wildlife Federation and Arizona State University in Tempe, authored the assessment.

Commentary: Lyle Goldstein: Sunshine Returns to the Korean Peninsula?

Politics

On Wednesday, Dec. 19, 2012, Park Geun-hye was elected South Korea’s new president, making her the first woman to hold the title. It’s a victory some say signals the beginning of a new era for the tension-riddled region. Lyle Goldstein, International Relations program visiting faculty and associate professor in the China Maritime Studies Institute of the U.S. Naval War College, comments on what Park’s election means for the future of South Korea and the country’s relationship with the United States and China.

Park Geun-hye’s election will come as a major relief to many strategists in Washington, given her pro-American credentials. Her opponent was inclined to fully reinstate the “sunshine policy” of a decade ago, a disposition that would have no doubt entailed a more discriminating look at the newly invigorated U.S.-Republic of Korea alliance. Irrespective of which candidate came to occupy the Blue House, South Koreans seemed to be looking for more sunshine and less inter-Korean tension. (more…)

UCLA Engineers Develop New Energy-Efficient Computer Memory Using Magnetic Materials

Technology

MeRAM is up to 1,000 times more energy-efficient than current technologies

By using electric voltage instead of a flowing electric current, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have made major improvements to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM. (more…)

Researchers Use Liquid Metal to Create Wires That Stretch Eight Times Their Original Length

Science

Researchers from North Carolina State University have created conductive wires that can be stretched up to eight times their original length while still functioning. The wires can be used for everything from headphones to phone chargers, and hold potential for use in electronic textiles. (more…)

Fossil of Ancient Marine Animal Reveals Softer Side

Science

A Yale scientist and colleagues in Britain have found a highly unusual ancient marine fossil that retains soft body parts as well as its shell, including limbs, eyes, gills and alimentary system. The fossil represents a new species of ostracod, a tiny crustacean related to crabs, lobsters and shrimps.

“Fossil ostracods often provide evidence of the relative ages of the rocks in which they occur, but it is very difficult to determine their relationship to living forms because only the shell is normally preserved,” said Derek E. G. Briggs, director of Yale’s Peabody Museum of Natural History and a co-author of the research. “This 425-million-year-old new form is remarkable in preserving the limbs and other anatomical features as well.” (more…)
