Your article has a picture of a “deer stone.” On it are engraved designs of reindeer that bear an astonishing resemblance to a tattoo borne by the 2,400-year old mummy discovered in 1993 in central Asia. Was this noticed by the researchers? Michelle BlanchardOlympia, Wash. Absolutely. William Fitzhugh, an expedition leader, says he was struck […]

Like most environmental journalism, the article describes the problem well but not the solution. It would be useful if information about native landscaping were included in this article as an alternative to non-native species. Frank HasslerChampaign, Ill. Your interesting piece on invasive plants touched upon, but otherwise ignored, mycoherbicides for control of noxious weeds. Mycoherbicides, […]

I was dismayed to see you publish an unsubstantiated and highly misleading claim that welfare “reform” is not harming children. The study dealt with the atypical welfare mothers able to find sustainable employment. For them, I don’t doubt that having enough money rather than too little would be an improvement. Unmentioned are the many unskilled […]

A new source of dioxins: Clean hands
Manufacturers have been adding the germ fighter triclosan to soaps, hand washes, and a range of other products for years. But here’s a dirty little secret: Once it washes down the drain, that triclosan can spawn dioxins.

The skinny on indoor ozone
Indoor concentrations of ozone tend to be far lower than those outside, largely because much gets destroyed as molecules of the respiratory irritant collide with surfaces and undergo transformative chemical reactions. New research identifies a hitherto ignored surface that apparently plays a major role in quashing indoor ozone: It’s human skin. And while removing ozone from indoor air should be good, what takes its place may not be, data indicate.

Frogs: Clues to how weed killer may feminize males
Atrazine, a widely used agricultural herbicide, not only can alter hormone levels in the developing frogs, but also perturb their physical development — and lead to an excess number of females, researchers report. Their new findings may help explain observations reported by a number of other research groups that at least in frogs, fairly low concentrations of atrazine can induce a feminization — or demasculinization.

Frogs: Weed killer creates real Mr. Moms
Several months back, a Berkeley undergraduate began witnessing distinctly odd behavior in frogs she was caring for in the lab. At about 18-months old, some frisky guys began regularly mounting tank mates, as if to copulate. Except that their chosen partner was invariably male. He had to be. Because genetically, every animal in the tank was male.

The FY 2011 budget: So much for transparency
Cabinet officials and other administration leaders met with reporters yesterday to outline the President’s Fiscal Year 2011 federal budget. That spending blueprint includes $147-billion-and-change for research and development programs. But in contrast to past years, details tended to be skimpy today — and any chance for followup or verification of apparent trends has proven more difficult than usual.

Obama: Climate’s rock star
A little over a half-hour ago, President Barack Obama wrapped up a stirring pep talk to his fellow world leaders attending the United Nations climate change meeting. He didn’t promise the world. Only that the United States could be depended upon to do its part in helping stem global greenhouse gas emissions and to fund measures that would help fund the world’s poorest and climate-beleaguered nations adapt. But what was especially interesting was to watch how the whole climate conference has waited with baited breath to learn what Obama would say: Could our President make promises that would at last galvanize action in the United States and accord among countries whose views, even yesterday, seemed poles apart?

U.N effectively locks out reporters, others in Copenhagen
For a year, the United Nations and national leaders have stumped around the world, championing the importance of the Copenhagen climate negotiations. It made this international conclave a must-see destination. And the UN responded by granting accreditation to huge numbers of government officials, UN officials, public-interest groups and journalists. In fact, to almost twice as many individuals as the conference center could hold. And that led to pandemonium today as the UN confronted literally thousands of people waiting to pick up their security badges – people this organization couldn’t or wouldn’t accommodate.
