Geomedia: Books: Rediscovering the science behind Thoreau's 'Walden'

Last summer, I had the opportunity to enjoy a personal tour around the world’s most famous kettle pond, Walden Pond in Concord, Mass., led by geologist Robert Thorson, who recently authored the book “Walden’s Shore: Henry David Thoreau and Nineteenth-Century Science.” The rainy, gray day did not diminish our hike or Thorson’s delight in sharing what he had learned from his research into Henry David Thoreau’s lifelong fascination with Walden Pond and the science behind his iconic book, “Walden.”

Geomedia: Books: To Tiktaalik and beyond

In 2008, Neil Shubin penned the terrific, “Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body,” in which he explored the stories of deep time as they are written in the details of our bodily architecture. As both a professor of anatomy and the paleontologist who discovered Tiktaalik, a transitional fossil between fish and amphibians, Shubin was ideally positioned to tell this tale.

Geomedia: Books: A brief history of our cosmic origins

In the 1980 television show “Cosmos,” astronomer Carl Sagan famously noted: “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” This scientifically and philosophically profound concept — that we are starstuff through and through — has been known for less than 50 years, and the history of its discovery was fraught with naysayers.

Geomedia: Books: Are we causing a sixth extinction?

Last year, Elizabeth Kolbert released her latest excellent book. Her previous volume, “Field Notes from a Catastrophe,” set a high bar for accessible, accurate science writing about environmental issues, but in my opinion, “The Sixth Extinction” surpasses it in several regards. Readers of this magazine will appreciate its solid geologic grounding and perspective, with entire chapters devoted to the end-Ordovician and end-Cretaceous extinctions, as well as sections on the principles of evolution and Earth history. Climate change, the focus of her earlier book, looms large here too, though it is just one of the many threats to the survival of our biosphere that Kolbert covers.

On the Web: Personalizing drought data with digital tools

One of the hardest parts of hazard mitigation is communicating risk to the public. With drought, people feel the heat while it’s happening but understanding how the current drought fits into past trends — and their implications for the future — is harder to grasp. Now, several online tools are available to help the public and decision-makers look at drought data.

Geomedia: 'Dinosaur 13' chisels away at the story behind discovery of Sue

The famous Tyrannosaurus rex "Sue" made headlines in the early 1990s, not only for being the most complete T. rex skeleton ever found, but also for the human drama that unfolded after the discovery. The story is the focus of a new documentary, "Dinosaur 13."

On the Web: Ka-pow! Superhero short films get kids thinking about climate change

The Green Ninja may sound like a spin-off of the “Power Rangers,” the live-action children’s television series featuring color-coded superheroes. But there’s a little less punch and a lot more thought going into this YouTube science show for kids.

Geomedia: Books: Science in fiction

As a science magazine, EARTH usually reviews nonfiction. This month, however, we are bringing you reviews of three recent novels with scientific themes that might make nice additions to your summer reading list. The three novels fall neatly into classic genres — the murder mystery, the high-stakes thriller and the science-infused fantasy — so hopefully there is a little something for everyone. Warning: spoilers follow.

Geomedia: Books: The earth system symphony

The planet is a symphony played by the orchestral sections of the atmosphere, hydrosphere, geosphere and biosphere, each of which includes many instruments. However, teasing out the myriad relationships in the concerto that is the earth system is daunting. Not only do the scales involved range from planetary to microscopic, but our observational records are also relatively short, and some features are inherently chaotic. Just understanding the basics of any one of the major components can take a lifetime.
