Safety practices lax in nanomaterials research labs
In this week’s Nature , researchers present a survey of university and public laboratories showing that lab workers are not using adequate safety equipment when working with nanomaterials.

Snowstorm and climate change
Reporting from Washington – As record snowfall buried the nation’s capital this week, the quickest joke around town was, “So much for global warming.” The quip was timely, given the recent controversies over Climategate — the release of e-mails allegedly showing some leading climate scientists trying to suppress criticism — and new questions about the integrity of the United Nations’ Intergovernmental Panel on Climate Change. After 55-plus inches of snow fell in the Washington area, critics are delighting in the irony, and those who warn of climate change are taking pains to say the snow fits the pattern of a warming world. So who’s right
FDA budget draws cries of ‘not enough’
Reporting from Washington – The Food and Drug Administration was sitting pretty last week, winning a significant budget increase while many other federal agencies faced the prospect of cut or frozen funding as the Obama administration confronts a 13-figure deficit. But a coalition of public interest advocates, patient groups and healthcare industry interests regulated by the FDA had a swift response: It’s not enough. “We are disappointed in the president’s budget request and
Photon scattering can create lasers in fiber optic cabling
Most lasers have operated along similar physical principles: a small, precisely dimensioned, closed cavity containing specific materials that will get incoming photons excited enough to band together and form a coherent laser beam. However, this isn’t the only way to get a material to lase, as it’s possible to get the same effect by taking advantage of the scattering of light. Researchers have now demonstrated a scattering-based laser that relies on light pumped into a 50 mile long fiber optic cable
Errors in climate report prompt a push for reform
Washington – A steady drip of unsettling errors is exposing what scientists are calling “the weaker link” in the Nobel Peace Prize-winning series of international reports on global warming.
