In what they believe to be the first survey of its kind in the United States, researchers at NYU Langone Medical Center have found that as many as 6 percent of adult New Yorkers who get "inked" -- in other words, those who get a tattoo -- have experienced some form of tattoo-related rash, severe itching or swelling that lasted longer than four months and, in some cases, for many years.

We are already reaping the rewards of the Montreal Protocol, with the ozone layer in much better shape than it would have been without the UN treaty, according to a new study in Nature Communications. Study lead author Professor Martyn Chipperfield, from the School of Earth & Environment at the University of Leeds, said: “Our research confirms the importance of the Montreal Protocol and shows that we have already had real benefits. We knew that it would save us from large ozone loss 'in the future', but in fact we are already past the point when things would have become noticeably worse.”

Biologists at UC San Diego have discovered that a tiny single-celled parasite may have a greater-than expected impact on honey bee colonies, which have been undergoing mysterious declines worldwide for the past decade. In this week’s issue of the journal PLOS ONE, the scientists report that a microsporidian called Nosema ceranae, which has been known to infect adult Asiatic and European honey bees, can also infect honeybee larvae.
