In the first nationally representative study to examine the relationship between survey measures of household firearm ownership and state level rates of suicide in the U.S., researchers at the Harvard School of Public Health (HSPH) found that suicide rates among children, women and men of all ages are higher in states where more households have guns. The study appears in the April 2007 issue of The Journal of Trauma.

"We found that where there are more guns, there are more suicides," said Matthew Miller, Assistant Professor of Health Policy and Management at HSPH and lead author of the study.

People watching the Super Bowl who saw how much they had already eaten -- in this case, leftover chicken-wing bones -- ate 27 percent less than people who had no such environmental cues, finds a new Cornell study.

The difference between the two groups -- those eating at a table where leftover bones accumulated compared with those whose leftovers were removed -- was greater for men than for women.

"The results suggest that people restrict their consumption when evidence of food consumed is available to signal how much food they have eaten," said Brian Wansink, the John S.

Society’s disapproval of alcohol, tobacco and gambling means that some investors -- mostly public institutions -- lose out while other investors gain on these undervalued “sin stocks,” according to a study conducted by the Sauder School of Business at the University of British Columbia.

Sauder Prof. Marcin Kacperczyk and co-author Prof. Harrison Hong of Princeton University analyzed stock markets and the impact they feel from society’s framework of morals, traditions and laws.

University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.

The findings, published online this week by the Proceedings of the National Academy of Sciences, likely are applicable to most photoswitchable fluorescent proteins, said S. James Remington, professor of physics and member of the UO Institute of Molecular Biology.

The blogosphere is all lit up with views and commentary on the "Framing Science" article by Matthew Nisbet and Chris Mooney. Interesting discussion can be found at Sandwalk, A Blog Aroung The Clock (and links within), Pharyngula, as well as Matthew Nisbet's site. Essentially, the article argues that scientists are losing the battle of popular opinion because they don't frame science in a way that normal folk can relate to. People glaze over when someone start to talk science. Unless scientists and science writers get better at communicating with the public, so the argument goes, we will lose valuable mind-space to interests that are better "framers", such as Conservative politicians and the Intelligent Design movement. If only scientists could choose better words, use friendlier concepts, and be more inclusive, surely everyone would see things our way, and society would be ruled by the concepts of pure science and reason.

As far as I can tell (and I'm not the first to say it), "framing" is little more than a neo-term for rhetoric, a.k.a. "spin". Nisbet and Mooney have framed rhetoric in a new way to make it new and exciting for scientists again.

Escape!

Last night, while Tony and Bobby were beating the bejesus out of each other over a game of Monopoly gone very bad, we faced a situation also fraught with violence, or at least potential violence: the escape of a mouse from Mousefarm.

I say "potential violence" because, if we study man's relationship to mouse so far, it always ends in...bummersville for the mouse. Especially when man is surprised, or startled by mus's rapid, darting shots along the wallboard--the movements that so often evoke the sound known as "eek!" In fact, I will proposed here that the basic relationship between mouse and man can be summed up in three words: Dart, eek!, WHAM!

Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere. But a new study suggests that, as a way to fight global warming, the effectiveness of this strategy depends heavily on where these trees are planted. In particular, tropical forests are very efficient at keeping the Earth at a happy, healthy temperature.

The researchers, including Ken Caldeira of Carnegie’s Department of Global Ecology and Govindasamy Bala at Lawrence Livermore National Laboratory, found that because tropical forests store large amounts of carbon and produce reflective clouds, they are especially good at cooling the planet.

The aphid Acyrthosiphon pisum depends on a bacterial symbiont, Buchnera aphidicola, for amino acids it can't get from plants. The aphid, in turn, provides the bacterium with energy and carbon as well as shelter inside specialized cells.

Such interdependent relationships are not unusual in the natural world.

Female stem cells derived from muscle have a greater ability to regenerate skeletal muscle tissue than male cells, according to a study at Children’s Hospital of Pittsburgh of UPMC.

The study, which is being published in the April 9 issue of the Journal of Cell Biology, is the first ever to report a difference in regenerative capabilities of muscle stem cells based on sex.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators at Stony Brook University have received U.S. Patent Number 7,179,448 for developing chimeric, or "combination," proteins that may advance the development of vaccines and diagnostic tests for Lyme disease.
