In evolutionary biology, there is a deeply rooted supposition that you can't go home again: Once an organism has evolved specialized traits, it can't return to the lifestyle of its ancestors.
Some of the world’s most threatened sharks and rays—ancient, cartilaginous fish species under severe pressure globally from over-fishing – need protection by CITES, which is meeting this week in Bangkok
A team of scientists led by the Wildlife Conservation Society (WCS) and the National University of Singapore (NUS), revealed in a new study, for the first time, the presence of the pathogenic chytrid fungus (Batrachochytrium dendrobatidis) in amphibians sampled in Singapore. And the American bullfrog may be a central player in the spread of the disease.

Chuanbing Tang at the University of South Carolina is developing new plastics that are “green” from the cradle to the grave. Given that the new polymers he’s working on often come from pine trees, firs and other conifers, he’s giving the word “evergreen” added resonance.
University of Utah researchers ran computer simulations to show that the snow-producing “lake effect” isn’t always enough to cause heavy snowfall, but that mountains or other surrounding topography sometimes are necessary too.
When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn’t matter that much. And that’s good news for reducing the uncertainty of climate model predictions.

A research team led by Arizona State University (ASU) senior sustainability scientist Ann Kinzig argues for an novel approach to climate change alleviation: target public values and behavior.
Newswise invites press release submissions from new and current members for inclusion in our Theme Wires on a variety of topics, including; Cancer Research, Environment and Climate Change, Nutrition, and Mental Health. Each wire is also open for sponsorships to promote your organization’s campaign, product, service, or news.
A team of researchers in Boston University’s Department of Earth and Environment have developed a new, bottom-up model for measuring on-road vehicle emissions. The model will be used to more accurately assess the effects of vehicle travel and traffic congestion on Massachusetts’ greenhouse gas emissions.
In a new study, Boston University researchers and collaborators have found that butterflies show signs of being affected by climate change in a way similar to plants and bees, but not birds, in the Northeast United States. The researchers focused on Massachusetts butterfly flight periods, comparing current flight periods with patterns going back more than 100 years using museum collections and the records of dedicated citizen scientists. Their findings indicate that butterflies are flying earlier in warmer years.
Using underwater video cameras to record fish feeding on South Pacific coral reefs, scientists have found that herbivorous fish can be picky eaters – a trait that could spell trouble for endangered reef systems.
A shift away from traditional coffee-growing techniques may be increasing the severity of an outbreak of 'coffee rust' fungus that has swept through plantations in Central America and Mexico, according to a University of Michigan ecologist who studies the disease.
Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into the atmosphere much faster than previously thought.
Samantha Borisoff, climatologist with the NOAA Northeast Regional Climate Center at Cornell University, reviews the origins and impact of the powerful snowstorm – dubbed “Nemo” by the national media – that struck the Northeast this past weekend.

Columbia Engineering and Georgia Institute of Technology researchers have published a study in the Proceedings of the National Academy of Sciences showing that certain volatile organic gases can promote cloud formation in a way never considered before by atmospheric scientists. They say this is the first time gases have been shown to affect cloud formation in this way and will “improve our ability to model cloud formation, an important component of climate.”
EarthViewer, a free, interactive app designed for the iPad, lets users explore the Earth’s history with the touch of a finger by scrolling through 4.5 billion years of geological evolution.
