Journal of Personality{DISSERTATION} Stories we tell about national trauma reflect our psychological well-being A new study by psychologists at the University at Buffalo and the F. W. Olin College of Engineering finds that in the aftermath of national trauma, the ability to make sense out of what happened has implications for individual well-being and that the kinds of stories people tell about the incident predict very different psychological outcomes for them.

Proceedings of the Royal Society B{DISSERTATION} Sex in the Caribbean: Environmental change drives evolutionary change -- eventually Hungry, sexual organisms replaced well-fed, clonal organisms in the Caribbean Sea as the Isthmus of Panama arose, separating the Caribbean from the Pacific, report researchers from the Smithsonian Tropical Research Institute and Scripps Institution of Oceanography. The fossil record shows that if a species could shift from clonal to sexual reproduction it survived. Otherwise it was destined for extinction, millions of years later.

Genome Biology and Evolution{DISSERTATION} After dinosaurs, mammals rise but their genomes get smaller Evidence buried in the chromosomes of animals and plants strongly suggests only one group -- mammals -- have seen their genomes shrink after the dinosaurs' extinction. What's more, that trend continues today, say Indiana University Bloomington scientists in the first issue of a new journal, Genome Biology and Evolution.

Psychological Science{DISSERTATION} Researchers develop 'brain-reading' methods It is widely known that the brain perceives information before it reaches a person's awareness. But until now, there was little way to determine what specific mental tasks were taking place prior to the point of conscious awareness. That has changed with the findings of scientists at Rutgers University in Newark and the University of California, Los Angeles.

Nature Nanotechnology{DISSERTATION} UCR scientists manipulate ripples in graphene, enabling strain-based graphene electronics Scientists at the University of California, Riverside, report the first direct observation and controlled creation via simple thermal manipulation of one- and two-dimensional ripples in graphene sheets. The result has important implications for controlling thermally induced stress in graphene electronics and represents the first step towards strain-based graphene engineering. The thermal contraction of graphene had been predicted theoretically, but the UC Riverside lab is the first to demonstrate and quantify the phenomenon experimentally.

Journal of Archaeological Science{DISSERTATION} UC scientists determine that ancient Maya practiced forest conservation -- 3,000 years ago An interdisciplinary team led by paleoethnobotanist David Lentz of the University of Cincinnati has concluded that not only did the Maya people practice forest management, but when they abandoned their forest conservation practices it was to the detriment of the entire Maya culture. This visit, the first allowed by the Guatemalan government by a North American university in more than 40 years, is the first of two that the UC team will be conducting. The team plans to return in February 2010.
