The next time you want to convince someone to vote for your favored political candidate, or to buy a certain product, use abstract language, say the authors of a new study published in the The Journal of Consumer Research. The study found that consumers respond  better to product descriptions when they are framed in abstract as opposed to concrete terms.

"Our finding that abstract messages have a stronger impact on buying intentions can be translated straightforwardly into the recommendation to use abstract language if you try to convince someone of the (positive or negative) consequences of buying a product, or of following your advice," the authors explain.

Results from a study recently published in the Lancet Oncology found that testing for high-risk types of the human papillomavirus (HPV) DNA is significantly more effective in preventing invasive cervical cancer than cytology (Pap testing) alone.

Two rounds of screening were performed in more than 90,000 women age 25-60. In phase one, women were randomly assigned to a control group with conventional cytology (Pap) only or to an intervention group where women had HPV DNA testing plus liquid-based cytology. In phase two, which was conducted two years later, with three to five years of follow-up, the control group received conventional cytology and the women in the intervention group received HPV testing alone.

Thanks to capitalism and a cultural heritage of individual freedom, Americans enjoy just about ever modern convenience imaginable and do almost anything they want. But, according to psychologists from Standford University and Swarthmore College, the amount of choice that results from such a decadent lifestyle may be unhealthy. The researchers say that too many choices cause Americans to ignore how the rest of the world feels about choice and may even make us selfish and depressed.

A new paper published in Zoologica Scripta argues that the distributions of the major primate groups are correlated with Mesozoic tectonic features and that their respective ranges are congruent with each evolving locally from a widespread ancestor on Pangea about 185 million years ago.

The new theory incorporates spatial patterns of primate diversity and distribution as historical evidence for primate evolution, while previous models of primate evolution had been limited to interpretations of the fossil record and molecular clocks, says author Michael Heads, a Research Associate of the Buffalo Museum of Science.

University of California, San Diego researchers say they have shown one way deadly brain tumors called gliomas evade drugs aimed at blocking the epidermal growth factor receptor (EGFR), a cell signaling protein that is crucial for tumor growth. They also say that a particular EGFR mutation is important not only to initiate the tumor, but for its continued growth as well. The findings appear this week in PNAS.

Not a whole lot of squid news this week, although the cephalopod mailing list continues to host a lively discussion, spurred by that coconut octopus story, of concepts like "tool use" and "intelligence". Everyone's got a different perspective! One of my favorite questions: is an archerfish that spits a jet of water to knock an insect off a branch a "tool user"? Is "using" a jet of water different from "using" a rock or a coconut shell?

2010 has just started with the best auspices to bring us exciting new science, and there comes a pledge to forecast what will happen in 2020. Oh, well - rest is not what I became a scientist for.

Making non-trivial predictions today for how will basic research be in subnuclear physics ten years down the line is highly non-trivial. For exactly the opposite reason that it is equally hard in several other fields of research.
