6:50 PM | Weekend Reads: Scientific Serendipity, Brain-Busting Toxins, Greenland Ice is Going, Going...
By Jason Bittel The Toxins That Threaten Our BrainsAs Florence Williams first told you in last year’s OnEarth cover story “Generation ToXic,” the brain development of U.S. children is at risk from an array of neurotoxins found in pesticides, industrial chemicals, and everyday household products. James Hamblin mirrors Williams’ reporting with an in-depth and similarly scary piece, which begins with a focus on how many IQ points a […]

4:31 PM | U.S. Biomass Energy Consumption Grows 60% from 2002 to 2013
U.S. biomass energy consumption grew more than 60% from 2002 to 2013. This growth is almost entirely due to increased consumption of biomass to produce biofuels, mainly ethanol but also a smaller amount of biodiesel and other biomass-based diesel fuels. In 2013, biomass accounted for about half of all renewable energy consumed and 5% of total U.S. energy consumed. Read more »

2:22 PM | Thirsty Rivers, Whaling in the Office, the Keeling Curve Budget Crisis
By Jason Bittel When the funding runs out: Earlier this week, scientists warned that carbon dioxide in the earth’s atmosphere had already topped the crucial 400 parts per million threshold for the year—two months earlier than it hit the same historically high measurement last year. Well, here’s some more bad news: the lab that takes those all-important measurements is about to run out of money. With government funding hard to come by and […]

1:15 PM | New Processing Method Makes LEDs Brighter, More Stable
Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gallium nitride (GaN) with a layer of phosphonic acid derivatives. Read more »

7:27 PM | Share the Bounty
By Ted Genoways Though it’s certainly easier to find local, sustainably grown meat and produce in America than it was 20 years ago, the deck nevertheless remains stacked against small farmers and sellers who would feed the steadily increasing demand for such fare. Many of our food-production system’s most dangerous and unsustainable practices—from pumping factory-farmed livestock full of antibiotics to depleting and polluting groundwater […]

3:25 PM | Richard Branson: “We Rely Too Heavily on Russia for Energy Supplies”
Richard Branson, an English business magnate and investor best known as the founder of Virgin Group, says in a recent blog post that the U.S. and EU must treat the situation in Crimea with a real sense of urgency, as Russia continues to intervene in Ukraine. Read more »

2:34 PM | The Rootworms Are Winning, Ohio Oil Spill, I, For One, Welcome Our New Snake Overlords
By Jason Bittel Anybody sensing a pattern?: A pipeline primarily owned by Sunoco leaked around 240 barrels of crude oil into an Ohio nature preserve earlier this week. Officials so far say there’s no threat to the public water supply and that the only effect to forest and wetland wildlife has been a single dead crayfish. (Ok, 10,000 gallons of crude dumped into a nature preserve and there’s only one dead crustacean? Color me skeptical.) Crews […]

1:17 PM | Calibrate your seismic intuition
On Tuesday we announced our new web app, modelr.io. Why are we so excited about it?  We love the idea that subsurface software can cost dollars, not 1000's of dollars.  We love the idea of subsurface software being online, not on the desktop. We love the idea that subsurface software can be open source. Here's our code! We love the idea of subsurface software that doesn't need a manual to master. We love the idea of subsurface software that runs on a tablet or a phone. We see software […]
