Human problems rarely occur in a vacuum, but persist as part of ongoing social interaction in which causes and effects are interwoven. One person's behavior can set the stage for what another does. A new study in the journal Family Process reveals that smoking can promote emotional connection for couples when both partners smoke.

Health-compromising behaviors, such as smoking or weight gain, may sometimes persist because they preserve stability in a vital close relationship. 

Humor is a powerful communications tool with potential political implications at various levels of society, as the recent Danish political cartoon representations of Islamic prophet Mohammad and the political repercussions and resulting economic boycotts demonstrated. A new paper by Darren Purcell, Melissa Scott Brown and Mahmut Gokmen looks at humor as an important form of popular culture in the creation of geopolitical worldviews.

A new map combining nearly three months of data from NASA's Fermi Gamma-ray Space Telescope is giving astronomers an unprecedented look at the high-energy cosmos. To Fermi's "eyes", the universe is ablaze with gamma rays from sources within the solar system to galaxies billions of light-years away.

A paper describing the 205 brightest sources the LAT sees has been submitted to The Astrophysical Journal Supplement. "This is the mission's first major science product, and it's a big step toward producing our first source catalog later this year," said David Thompson, a Fermi deputy project scientist at NASA's Goddard Space Flight Center in Greenbelt, Md.

While science is of tremendous societal importance, it is difficult to probe the often hidden world of scientific creativity. Most studies of scientific activity rely on citation data, which takes a while to become available because both the cited publication and the publication of a particular citation can take years to appear. In other words, citation data observes science as it existed years in the past, not the present.

What we need is a Map Of Science.

Enter a group of Los Alamos researchers who created a high-resolution graphic depiction of the virtual trails scientists leave behind when they retrieve information from online services.

The creation of long platinum nanowires at the University of Rochester could soon lead to the development of commercially viable fuel cells.

Described in a paper published today in the journal Nano Letters, the new wires should provide significant increases in both the longevity and efficiency of fuel cells, which have until now been used largely for such exotic purposes as powering spacecraft. Nanowire enhanced fuel cells could power many types of vehicles, helping reduce the use of petroleum fuels for transportation, according to lead author James C. M. Li, professor of mechanical engineering at the University of Rochester.

A 7-year-old girl from Long Island, NY, is on her way home a little more than four weeks after receiving a historic surgery that involved the removal and partial re-implantation of six organs in order to resect an abdominal tumor that otherwise would be inoperable. The 23-hour surgery, which began on Feb. 6, was led by Dr. Tomoaki Kato at NewYork-Presbyterian Morgan Stanley Children's Hospital, and is the first reported pediatric case of its kind.

Most people consume far too much salt, and a University of Iowa researcher has discovered one potential reason we crave it: it might put us in a better mood.

UI psychologist Kim Johnson and colleagues found in their research that when rats are deficient in sodium chloride, common table salt, they shy away from activities they normally enjoy, like drinking a sugary substance or pressing a bar that stimulates a pleasant sensation in their brains.

"Things that normally would be pleasurable for rats didn't elicit the same degree of relish, which leads us to believe that a salt deficit and the craving associated with it can induce one of the key symptoms associated with depression," Johnson said.

- Unique Survey Shows Much Room for Originator Pharmaceutical Companies to Improve Their Understanding of Generic Competition

The Healthcare and Science business of Thomson Reuters today released the white paper, The Five Myths of Generic Competition, highlighting what originator pharmaceutical and biotech companies can do to improve their forecasting of the likely timing, source and intensity of competition from generic drugs.

The findings in this white paper are based on an independent survey of commercial professionals in pharmaceutical and biotech companies. The research was conducted by Thomson Reuters during May and June 2008.

LONDON, March 11 /PRNewswire/ --

New research released to mark No Smoking Day (11 March) shows more than one in three (36%) of the nine million smokers in Great Britain are thinking about or planning to cut down or quit as a direct result of the economic downturn. The poll also shows that one in ten (9%) will be taking the first step and making a quit attempt on No Smoking Day.

No Smoking Day President and Dragons' Den star, Duncan Bannatyne, commented on the findings: Everybody is feeling the pinch during the current recession.

For smokers, who can spend over GBP2000 a year on cigarettes, it's particularly tough, so for those who are ready to quit there has never been a better time.

This statement about natural selection is the last sentence of Adaptation and Natural Selection, George Williams' masterpiece about evolution. George Williams is one of the unsung heroes of 20th century science. An evolutionary biologist I know (who shall remain anonymous to spare him/her public shaming) claimed not to know who was George Williams. I was/still am aghast. This anonymous evolutionary biologist is the inspiration for this post, indeed for my series of citation classics (see also here).
