Way back in 1811 and 1812, a series of over 1,000 earthquakes rocked the Mississippi River between St. Louis and Memphis. One was so powerful that it caused the river to run backwards for a few hours. The infamous New Madrid earthquakes of 1811–1812 rang church bells in Boston, which is 1,200 miles from St. Louis. Today, scientists say that the 150-mile-long New Madrid Seismic Zone has a terrifying 40% chance to blast in the next few decades, impacting 7 states – Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee and Mississippi – with 715,000 buildings damaged and 2.6m people left without power.

Unlike California, which has been super-prepared since the last major earthquake hit hard enough to delay the World Series, the New Madrid fault area has been sitting blissfully by. In case the “40 percent” statistic didn’t bother you, this should: The New Madrid fault has an impact zone ten times as big as its more famous San Andreas cousin.

Not good!

Workers took the Keystone oil pipeline offline on Thursday after it spilled 5,000 barrels of oil in rural South Dakota, officials said.

A TransCanada crew shut down the pipeline at 6 a.m. Thursday morning after detecting an oil leak along the line, the company said. The leak was detected along a stretch of the pipeline about 35 miles south of a pumping station in Marshall County, South Dakota.

TransCanada estimates the pipeline leaked 5,000 barrels of oil, or about 210,000 gallons, before going offline. The company said it’s working with state regulators and the Pipelines and Hazardous Materials Safety Administration to assess the situation.

On Saturday, a record 24.6% of total electricity came from wind power sources in the 28 countries of the European Union. The majority of this wind electricity was generated offshore (91.3%) vs onshore (8.7%).

With Europe moving into the high wind production winter period, we expect a new season of records being broken. And with massive scale construction continuing for offshore wind farms, these records of 2017 will soon look quaint.

The amounts of electricity generated were enough to power 197 million European households or 68% of all industrial electricity needs. Europe has about 500 million total people, with a land mass very close to that of the USA.

Physicists have proposed a way to test quantum gravity that, in principle, could be performed by a laser-based, table-top experiment using currently available technology. Although a theory of quantum gravity would overcome one of the biggest challenges in modern physics by unifying general relativity and quantum mechanics, currently physicists have no way of testing any proposed theories of quantum gravity.

Now a team of seven physicists from various countries, S. Dey, A. Bhat, D. Momeni, M. Faizal, A. F. Ali, T. K. Dey, and A. Rehman, have come up with a novel way to experimentally test gravity using a laser-based experiment. They have published a paper on their proposed test in a recent issue of Nuclear Physics B.

One reason why testing quantum gravity is so challenging is that its effects appear only at very high-energy scales and their corresponding tiny length scales. These extreme scales, which are very near the Planck scale, are roughly 15 orders of magnitude beyond those accessible by the Large Hadron Collider (LHC), by far the world’s highest-energy experiment.

Struggling to steer its economy away from oil dependence, Saudi Arabia announced an audacious plan to build a $500 billion super-city that is intended to become a world-class business hub.

Saudi Arabia is moving toward a “new generation of cities,” said Mohammed bin Salman, crown prince of the Middle Eastern kingdom, during one of his rare appearances before the press on October 24. The first of its kind, the city, to be named Neom, would be powered by green energy and have no room for “anything traditional,” he said.

Last week saw the launch of the world’s first floating offshore wind farm. Located in the North Sea off the coast of Peterhead, Scotland, the wind farm consists of five enormous horizontal-axis turbines that together can generate 30 megawatts of electricity. That’s enough to power about 20,000 homes.

The wind farm is called Hywind, and it’s been in the making for over 15 years, spearheaded by Norwegian energy firm Statoil. Key facts about the turbines and their location include:
