Man-made underwater sound may have wider ecosystem effects than previously thought
February 5, 2016 07:21 AM -

Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton.

The study, reported in the journal Scientific Reports published by Nature, found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

Obama Rejects Keystone XL Pipeline
November 9, 2015 06:41 AM - Center for Biological Diversity

In a crucial victory for the climate, wildlife and the millions who spoke against it, President Obama rejected the Keystone XL project today, saying that building the tar sands oil pipeline is not in the national interest.

Over the past four years, scientists, environmentalists, tribes, farmers, celebrities and business people joined forces to fight the pipeline, with more than 2 million comments submitted to the U.S. State Department, tens of thousands participating in rallies against Keystone in all 50 states, and thousands of citizens arrested in peaceful civil disobedience.

“This is a historic moment, not just for what it means about avoiding the impacts of this disastrous pipeline but for all of those who spoke out for a healthy, livable climate and energy policies that put people and wildlife ahead of pollution and profits,” said Valerie Love with the Center for Biological Diversity. “President Obama did the right thing, but he didn’t do it alone: Millions of Americans made their voices heard on this issue, and will continue pressing Obama and other political leaders to do what’s necessary to avoid climate catastrophe.”

Bioart: An Introduction

Cell Press via EurekAlert!

Joe Davis is an artist who works not only with paints or pastels, but also with genes and bacteria. In 1986, he collaborated with geneticist Dan Boyd to encode a symbol for life and femininity into an E. coli bacterium. The piece, called Microvenus, was the first artwork to use the tools and techniques of molecular biology. Since then, bioart has become one of several contemporary art forms (including reclamation art and nanoart) that apply scientific methods and technology to explore living systems as artistic subjects. A review of the field, published November 23, can be found in Trends in Biotechnology.

Bioart ranges from bacterial manipulation to glowing rabbits, cellular sculptures, and--in the case of Australian-British artist Nina Sellars--documentation of an ear prosthetic that was implanted onto fellow artist Stelarc's arm. In the pursuit of creating art, practitioners have generated tools and techniques that have aided researchers, while sometimes crossing into controversy, such as by releasing invasive species into the environment, blurring the lines between art and modern biology, raising philosophical, societal, and environmental issues that challenge scientific thinking.
