During evaporation of natural and synthetic K–Mg–Cl brines, the formation of almost square plate-like crystals of potassium carnallite (potassium chloride magnesium dichloride hexa­hydrate) was observed. A single-crystal structure analysis revealed a monoclinic cell [a = 9.251 (2), b = 9.516 (2), c = 13.217 (4) Å, β = 90.06 (2)° and space group C2/c]. The structure is isomorphous with other carnallite-type com­pounds, such as NH4Cl·MgCl2·6H2O. Until now, natural and synthetic carnallite, KCl·MgCl2·6H2O, was only known in its ortho­rhom­bic form [a = 16.0780 (3), b = 22.3850 (5), c = 9.5422 (2) Å and space group Pnna].

While every mode of transportation in the U.S. will be affected as the climate changes, potentially the greatest impact on transportation systems will be flooding of roads, railways, transit systems, and airport runways in coastal areas because of rising sea levels and surges brought on by more intense storms, says a new report from the National Research Council.

Rates of physical and sexual abuse of children have declined over the last 20 years, but for reasons not fully understood, says a new report from the Institute of Medicine.

A commentary published in Nature calls for a moratorium on clinical uses of heritable human genome editing and the establishment of an international governance framework.

An international commission has been convened by the U.S. National Academy of Medicine, the U.S. National Academy of Sciences, and the Royal Society of the U.K., with the participation of science and medical academies around the world, to develop a framework for scientists, clinicians, and regulatory authorities to consider when assessing potential clinical applications of human germline genome editing.

California State Senator Kevin de Leon says he’ll introduce legislation next month to get the state’s public employees retirement system off of coal.

Just back from ho-hum international talks in Lima, where he was a member of California's delegation, de Leon spoke at a conference in Oakland. It was sponsored by NextGen Climate, a nonpartisan group founded by billionaire philanthropist Tom Steyer to raise the profile of climate change among issues in the U.S. political debate.

“With coal power in retreat, and the value of coal dropping, it’s time for us to lead again in moving our massive state portfolios to lower carbon investments,” De Leon said. “Divestment is about matching your values with your investment strategy — and still seeing positive financial returns… California has prohibited its energy companies from buying or importing coal power, and state funds should match that.”

De Leon proposes to divest the nation’s two largest public pension funds from coal. The California Public Employees Retirement System, or CALPERS, is the nation’s largest, controlling about $295 billion as of the end of September.  The California School Teachers Retirement System is a sister fund for pensions of nearly 850,000 California teachers. CALSTRS controls another $187.1 billion dollars in potential investments.

Burning coal for energy is a major source of greenhouse gases that are warming the planet. The move would lend momentum to a divestment movement already underway, largely targeted at investment funds belonging to colleges and universities nationwide.

Stanford and Pitzer College in Claremont are among a dozen universities that have pulled investments out of the coal industry. But others, including the University of California have refused.

House Speaker Nancy Pelosi and Senate Majority Leader Mitch McConnell, in a rare joint statement on Saturday, declined an offer from the White House to make rapid COVID-19 tests available for Congress.

"Congress is grateful for the Administration's generous offer to deploy rapid COVID-19 testing capabilities to Capitol Hill, but we respectfully decline the offer at this time," Pelosi and McConnell said. "Our country's testing capacities are continuing to scale up nationwide and Congress wants to keep directing resources to the front-line facilities where they can do the most good the most quickly."

McConnell, R-Ky., plans to bring the Senate back into session on Monday, while Pelosi, D-Calif., and House Majority Leader Steny Hoyer, D-Md., said this week the House would not bring representatives back over coronavirus fears.

On Friday, Health and Human Services Secretary Alex Azar said on Twitter that the Trump administration would send three Abbott "point of care testing machines and 1,000 tests for their use" to Capitol Hill.

President Trump on Saturday tweeted: " No reason to turn it down, except politics. We have plenty of testing. Maybe you need a new Doctor over there. Crazy Nancy will use it as an excuse not to show up to work!"

Pelosi and Hoyer said they made the decision based on advice from the Capitol's attending physician, Brian Monahan. "The House physician's view was that there was a risk to members that was one he would not recommend taking," Hoyer said Tuesday.

So far, Rand Paul of Kentucky is the only senator to have tested positive for the coronavirus. In the House, seven members have tested positive or presumed to be positive for the coronavirus.

On Friday, McConnell shared guidelines from Monahan urging lawmakers and staff to maintain six feet of distance, limit the number of people in offices and to wear masks when possible.

Monahan has told Republican leaders that his office does not have the capacity to proactively test all 100 senators and can only test those who are ill, Politico reported.

We’ve all done it. Gone to the beach. Hunkered up against the cliffs to get out of the sun. And not thought about what’s right above us.

“Even though you’re sitting amongst store fronts, large communities, private residences, it still is a wild place,” said Brian Ketterer, Coastal Division Chief for California State parks. 

It’s normal for cliffs to erode as water, wind and human contact all work to break them down.

“If you’re going to be that close that you can see cracks and fissures in the soil content itself, that probably means that you’re sitting or standing too close to that bluff area,” said Ketterer 

Look out for posted signs and ask life guards if it’s safe, but know that this isn’t going to get better over time. Sea level rise – part of our climate crisis –could mean more erosion, which could mean even more cliff collapses.
