Walden Pond’s Enduring Lessons

Kevin Hooyman

When a professor does years of research and teaching on a topic related to this particular pond, and then takes the additional effort to share his observations in cogent form as an op-ed, we believe it is worth at least 5-10 minutes of reading time:

What the Muck of Walden Pond Tells Us About Our Planet

By

In 1845, Henry David Thoreau repaired to a cabin in the woods beside Walden Pond “to front only the essential facts of life, and see if I could not learn what it had to teach.” During the last two years, my students and I have come to that same pond to see what we could learn from the sediments beneath it.

Keeping The Science Moving Forward, Rather Than Sideways or Backwards

It is a bit of a mystery story, worthy of the time if you care about bees (a minor character here) and especially if you care about the moral character of scientists while under pressure:

Scientists Loved and Loathed by an Agrochemical Giant

With corporate funding of research, “There’s no scientist who comes out of this unscathed.”

The State Of Great

This article, by Adam Nagourney and science writer Henry Fountain, gives climate-concerned citizens everywhere hope that recent tectonic shifts on the political landscape in the USA will not result in complete abandonment of reason within all the states of that union:

LOS ANGELES — Foreign governments concerned about climate change may soon be spending more time dealing with Sacramento than Washington.” Continue reading

For the Birds: a Message to North American Policymakers

 

The State of North America’s Birds 2016

The State of North America’s Birds 2016

We continue to laud the importance of eBird on this site, gaining special importance as it becomes more and more clear that wildlife doesn’t acknowledge political borders. The data gleaned from tens of thousands of Canadian, Mexican and U.S. citizen scientists who contribute to eBird indicate that more than 350 species in North America migrate up and down Canada, the U.S.A, and Mexico over the course of a calendar year.

And according to the recently released State of North America’s Birds 2016 report, those three countries—their governments, and their societies—need to step up and do more to preserve our continent’s spectacular and shared natural heritage of birdlife. This report is the first-ever scientific conservation assessment of all 1,154 bird species in North America, and it was only possible because of the tremendous scale and big-data capabilities of citizen-science….

Among the many takeaways from eBird maps and models includes one of relevance to our property, Chan Chich Lodge, located on 30,000 acres of Belizean forest in the Yucatan peninsula.

The Yucatan Peninsula is one of North America’s most vital bird habitat regions

The Yucatan Peninsula is one of North America’s most vital bird habitat regions

Not only is the Yucatan rich with endemic birdlife, it’s a critical wintering area for more than 120 birds species that migrate from Canada and the U.S.A. In winter, the entire population of Magnolia Warblers relies on an area of tropical forest in Mexico only 1/10 the size of its boreal forest breeding range, with the Yucatan as the bull’s-eye of their wintering range.

Top Shelf Infographics For 128 Years

Thanks to the fancy-fine publisher, Taschen, for collecting this particularly powerful informative art form into one book:

A History of Knowledge

The best infographics from the National Geographic archives

Back in the days when the information age was a distant dream and the world a more mysterious place, National Geographic began its mission to reveal the wonders of history, popular science, and culture to eager audiences around the globe. Since that 1888 launch, the world has changed; empires have risen and crumbled and a galaxy of information is today only a click away. But National Geographic endures; its calm, authoritative voice is as respected as ever amid the surfeit of data in our daily lives. Continue reading

Better Nets, Better Fishing

Fishermen Team Up With Scientists To Make A More Selective Net

FRED BEVER

Some New England fishermen are pinning their hopes on a new kind of trawl net being used in the Gulf of Maine, one that scoops up abundant flatfish such as flounder and sole while avoiding species such as cod, which are in severe decline.

For centuries, cod were plentiful and a prime target for the Gulf of Maine fleet. But in recent years, catch quotas have been drastically reduced as the number of cod of reproductive age have dropped perilously low. Continue reading

In the fall of 1969, behind the closed door of an otherwise empty seminar room at Hebrew University, two psychologists began a collaboration that would upend the understanding of human behavior. Those first conversations were filled with uproarious laughter and occasional shouting, in a jumble of Hebrew and English, which could sometimes be heard from the hallway. Continue reading

Sound-Recognition Software Advances

MIT-SoundRec-1_0.jpg

The researchers’ neural network was fed video from 26 terabytes of video data downloaded from the photo-sharing site Flickr. Researchers found the network can interpret natural sounds in terms of image categories. For instance, the network might determine that the sound of birdsong tends to be associated with forest scenes and pictures of trees, birds, birdhouses, and bird feeders. Image: Jose-Luis Olivares/MIT

From Larry Hardesty at the news office of the Massachusetts Institute of Technology an interesting article on machine-learning, which we thought was going to be about a new app for birders but it is a much broader finding:

Computer learns to recognize sounds by watching video

Machine-learning system doesn’t require costly hand-annotated data.

Watch Video

In recent years, computers have gotten remarkably good at recognizing speech and images: Think of the dictation software on most cellphones, or the algorithms that automatically identify people in photos posted to Facebook. Continue reading

Be The Bee

Science, as a section of the daily newspaper of old, was geek-out territory. In the modernizing news organization, it has every bit of that old intensity, magnified by the wonders of technology. This little item demonstrates the point:

You’re a Bee. This Is What It Feels Like.

We’re taking you on a journey to help you understand how bees, while hunting for pollen, use all of their senses — taste, touch, smell and more — to decide what to pick up and bring home.

Set your meetings, phone calls and emails aside, at least for the next several minutes. That’s because today you’re a bee.
