Cream may ward off jellyfish stings, Stanford study suggests

Two dozen volunteers bravely exposed their arms to jellyfish tentacles as part of a new Stanford University School of Medicine study to test a topical, over-the-counter cream designed to protect against stinging nettles. Fortunately for the volunteers, the cream appeared to be relatively effective.

“It didn’t completely inhibit the stings, but it came pretty darn close,” reported Alexa Kimball, MD, MPH, an assistant professor of dermatology who directed the study. The study appears in

‘The Day After Tomorrow’ – fact or fiction?

The Day After Tomorrow – the latest Hollywood blockbuster movie released yesterday – depicts an extreme rapid climate change event following the sudden shutdown of the North Atlantic overturning circulation due to global warming. The film by Roland Emmerich, maker of ‘Independence Day’, is a dramatic portrayal of possible consequences of climate change.

Could this really happen?

The UK is taking the lead in rapid climate change research to try to answer that question. A

Thick marine beds of siderite suggest early high carbon dioxide in atmosphere

Carbon dioxide and oxygen, not methane, were prevalent in the Earth’s atmosphere more than 1.8 billion years ago as shown by the absence of siderite in ancient soils but the abundance of the mineral in ocean sediments from that time, according to a Penn State geochemist.

“The absence of siderite in some ancient soils has been linked to low carbon dioxide levels in the atmosphere, levels that would be too low to compensate for the cooler sun 2.2 billion years ago,” says Dr. Hiroshi Ohmot

Hollywood 10-day ice age highly unlikely

Hollywood’s latest disaster movie, The Day After Tomorrow, is about to be released. It is a fictional account of the havoc wreaked by out-of-control climate as North America is beset by the chilling beginnings of a new Ice Age in the course of 10 days. The movie features numerous catastrophic weather events including hurricanes, tornadoes, floods, and tidal waves striking New York.

“It’s a good yarn,” said Dr Tony Haymet, Chief of CSIRO Marine Research. “Like many of the catastroph

Global warming could lead to fast freeze, warns University of Ulster scientist

Dramatic climate change as a result of global warming could happen in a single lifetime – instead of being a slow process evolving over centuries, according to a University of Ulster academic.

Professor Marshall McCabe of the School of Environmental Sciences said that given the right set of circumstances, “a climate can flip in a lifetime”. And the result could be the return of Arctic conditions last seen in the British Isles thousands of years ago.

He said that the North Atlantic

Study helps satellites measure Great Lakes’ water quality

Ohio State University engineers are helping satellites form a clearer picture of water quality in the Great Lakes.

The study — the first ever to rate the effectiveness of various computer models for monitoring the Great Lakes — might also aid studies of global climate change.

As algae flourishes in the five freshwater lakes every summer, satellite images show the water changing color from blue to green, explained Carolyn Merry, professor of civil and environmental engineeri
