  • EPA Spilled, but Didn’t Dump, the Toxics That Ended up in Colorado’s River

    The short-term, expedient result of ignoring environmental impacts may be greater immediate profit for some, but the long-term impact is higher costs and lower profit, and many of those higher costs must be borne by all of us. Many of the companies that made the mess will be long gone before many of the bills…

  • An Algorithm to Investigate Unwelcome Plankton

    An Algorithm to Investigate Unwelcome Plankton

    Computer scientists at Columbia University will work with oceanographers to understand what has caused an unusual plankton-like species to rapidly invade the Arabian Sea food chain, threatening fisheries that sustain more than 100 million people.

  • Paleontologists Are Unzipping Our Genes

    Paleontologists Are Unzipping Our Genes

    Recently, paleontologists have used genomics to delve into the lives of ancient humans. These studies have capitalized on futuristic techniques to reveal the genealogy, travel plans and sex lives of our ancestors.

  • Revising the Toxic Substances Out-of-Control Act

    An unregulated chemical industry is an invitation for disaster. Fortunately, there is at least one place in America where regulation of toxic chemicals is taken seriously—California (of course).

  • The Otherworldly and Elusive Life Beneath Antarctica’s Ice

    The Otherworldly and Elusive Life Beneath Antarctica’s Ice

    While renowned for the penguins, Antarctica is perhaps equally well known for what it doesn’t have: basically, anything else. But scientist Steven Chown says the view that the icy continent lacks life is “simply not true.”

  • Subsurface Discovery Sprouts a New Branch on the Tree of Life

    Subsurface Discovery Sprouts a New Branch on the Tree of Life

    Last week a study published in Nature pulled the veil on a branch of the bacterial tree of life that has evaded detection for nearly a century and a half. The study used cutting edge genome sequencing and savvy bioinformatics techniques to make this remarkable discovery.

  • From the Nile to the Sundarbans: the Undergraduate Capstones

    From the Nile to the Sundarbans: the Undergraduate Capstones

    This spring, students in the Undergraduate Program in Sustainable Development presented innovative solutions to sustainability issues as part of their Capstone Workshop. Their clients ranged from the United States Military Academy at West Point to the Sabin Center for Climate Change Law.

  • The Right Wing’s Endless War on Environmental Regulation

    The right wing attack on environmental regulation is a fundamental political mistake. Conservatives are correct in assuming that Americans mistrust big organizations and powerful institutions, but they should remember that the public counts on these powerful organizations to protect them.

  • Fragile States Use Geospatial Data and Maps to Better Manage Natural Resources

    Fragile States Use Geospatial Data and Maps to Better Manage Natural Resources

    Some of the world’s poorest nations have an abundance of natural resources, but also have suffered under recent conflicts. Learning how to manage these resources strategically and sustainably can help accelerate growth and development. A new web-based mapping tool may be able to help them do that.
