Long-lost continent found submerged deep under Indian Ocean

An ancient continent that was once sandwiched between India and Madagascar now lies scattered on the bottom of the Indian Ocean.

The first clues to the continent’s existence came when some parts of the Indian Ocean were found to have stronger gravitational fields than others, indicating thicker crusts. One theory was that chunks of land had sunk and become attached to the ocean crust below.  Continue reading

Thanks to Wired for this (click the image above to go to the video) informative brief on the next wave of scientifically improved coffee:

Get Ready for a Coffee Renaissance. Thanks, Genetics!

Scientists have sequenced the genome of the coffee plant and made the data public. That means we’re about to see a coffee renaissance.

Model Mad, Canada

Canadian scientists offer support to muzzled US counterparts

For nine years under Canada’s previous government, science suffered harsh restrictions. Now US scientists may be facing a similar fate

by Ashifa Kassam in Toronto

Canadian scientists – who were muzzled for nearly a decade by the country’s previous Conservative government – have been making contact with their counterparts in the US to offer their support and solidarity amid mounting fears that Donald Trump’s presidency will seek to suppress climate science.

For nine years, scientists with Canada’s federal government grappled with what many described as an all out assault on science. Continue reading

Thanks to Anthropocene for a great title to this summary of important recent research finding:

From the swamps of the Potomac, new hope for green electronics

Protein filaments just 3 nanometers wide that are produced by certain species of bacteria could be a key to environmentally friendly electronics manufacturing, according to microbiologists at the University of Massachusetts at Amherst.

Scientists discovered the filaments, dubbed “nanowires,” about 5 years ago. Bacteria use them to make electrical connections with other bacterial cells or to generate reactions with metals in the environment. Continue reading

Prioritizing The Key Variable In Tomato Breeding

28tomato-blog427We always wondered why, with the selective breeding of tomatoes, experts favored appearance over flavor. We have an answer in “A Genetic Fix to Put the Taste Back in Tomatoes” by Kenneth Chang:

Over the decades, taste has drained out of supermarket tomatoes.

Harry J. Klee, a professor of horticultural sciences at the University of Florida, thinks he can put it back in within a couple of years. Continue reading

Any story with Metamorphosis in it is bound to get our attention, but a long-forgotten scientist getting her due is the intrigue that makes this story by JoAnna Klein–A Pioneering Woman of Science Re‑Emerges After 300 Years–coinciding with the republication of this book below, worthy of the read:metamorph

Maria Sibylla Merian, like many European women of the 17th century, stayed busy managing a household and rearing children. But on top of that, Merian, a German-born woman who lived in the Netherlands, also managed a successful career as an artist, botanist, naturalist and entomologist.:

“She was a scientist on the level with a lot of people we spend a lot of time talking about,” said Kay Etheridge, a biologist at Gettysburg College in Pennsylvania who has been studying the scientific history of Merian’s work. “She didn’t do as much to change biology as Darwin, but she was significant.” Continue reading

Tomatillo Fossils, 52 Million Years Old, Are Discovered in Patagonia

By Nicholas St. Fleur

The nightshades have an ominous reputation, but this large plant family is more than just its most poisonous members, like belladonna. It contains more than 2,400 different species, including some of the most widely consumed fruits and vegetables in the world, such as potatoes, tomatoes and peppers. Continue reading

Walden Pond’s Enduring Lessons

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.”

This article, by Adam Nagourney and Henry Fountaindec, 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:

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.

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
