Greenpeace Announces Campaign to Make Duke Energy the Clean Energy Company the U.S. Deserves

Greenpeace

Greenpeace USA Executive Director Phil Radford announced a campaign on Feb. 14 to make Duke Energy the clean energy company that North Carolina and the U.S. deserve. The announcement follows a protest and demonstration Feb. 13 in which 16 Greenpeace activists were arrested at a Progress Energy coal plant in Asheville, N.C. after unfurling a huge banner atop a smoke stack that read "Duke Energy: the climate needs real Progress." Duke Energy and Progress Energy are seeking a merger which would create the largest utility company in the U.S.

From Phil Radford's announcement: (For the full announcement, click here.)

"Today, I'm officially announcing our campaign to make Duke Energy the clean energy company that North Carolina and the United States deserve.

"We must shine a light on Duke's activities in 2012 because this is a make or break year for the climate, and Duke is at the center of it. The merger alone is enough to warrant an extra level of scrutiny—and has in fact been delayed this far by FERC (The Federal Energy Regulatory Commission) because of concerns about the company holding an energy monopoly in North Carolina. North Carolina ratepayers don't have a choice about where they get their energy. Despite a committed local movement opposing the most recent rate hike, they're seeing a 7.2 percent increase on their electricity bills in March, not to pay for an investment in renewable energy, but to invest more in new coal projects like the Cliffside plant. Enough is enough—Duke ratepayers have said loudly and clearly that they don't want to pay for more investments in dirty energy.

"And Duke Energy also holds a unique position in energy politics right now. It is currently the third largest emitter of CO2 in the U.S.—and that's before it takes on Progress Energy's dirty fleet. CEO Jim Rogers has spoken openly about the threat of climate change and pollution controls for coal plants, and yet Duke holds a membership in the industry group ERCC (Electric Reliability Coordinating Council), a group that was aggressively lobbying against the recently passed Mercury Rule.  It's no secret that Duke's money and influence—$6.5 million in lobbying dollars in 2010—could have a significant impact in U.S. energy policy. To top it all off, this year, Rogers has been the lead fundraiser for the Democratic National Convention, to be held in Charlotte where Duke Energy is based, lending the Democrats $10 million dollars to pay for the convention.

"On 60 Minutes in 2009, Jim Rogers said, "I remember the first time I took a helicopter to look down at a power plant like this, I was 41 years old, and I said, 'Oh my goodness, I'm responsible for that?'" He is. As long as Rogers guides the decisions of Duke Energy, he's responsible for dozens of polluting plants around the country that compromise our children's health and the health of our climate, and the mountains that are blown up to mine the coal he burns in these plants. He's responsible for the 15,714 asthma attacks, 1,447 heart attack, and 951 premature deaths Duke's coal plants cause every year. And Duke is soon to be responsible for Progress's fleet and the pollution that comes with it.

"We're asking Duke Energy to:

  • Not renew a single new contract for mountaintop removal coal
  • Deliver at least a third of Duke's energy from renewable sources by 2020.
  • Quit coal altogether by 2030.

"Our communities and our climate can't wait any longer for real action on the climate."

Just in time for Halloween, scientists at Cornell University have published some frightening research, especially if you're an insect!

The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.

"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."

The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.

They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.

They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.

But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.

"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.

What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.

It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.

To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.

First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.

Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.

University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.

"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."

Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.

Hoy agreed.

"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.

A NASA spacecraft has successfully collected a sample from the Bennu asteroid more than 200 million miles away from Earth. The samples were safely stored and will be preserved for scientists to study after the spacecraft drops them over the Utah desert in 2023, according to the Associated Press (AP).
