Military develops device that can disappear after use

Phys.org:
A polymer that self-destructs? While once a fictional idea, new polymers now exist that are rugged enough to ferry packages or sensors into hostile territory and vaporize immediately upon a military mission's completion. The material has been made into a rigid-winged glider and a nylon-like parachute fabric for airborne delivery across distances of a hundred miles or more. It could also be used someday in building materials or environmental sensors.

The researchers will present their results today at the American Chemical Society (ACS) Fall 2019 National Meeting & Exposition.

"This is not the kind of thing that slowly degrades over a year, like the biodegradable plastics that consumers might be familiar with," says Paul Kohl, Ph.D., whose team developed the material. "This polymer disappears in an instant when you push a button to trigger an internal mechanism or the sun hits it." The disappearing polymers were developed for the Department of Defense, which is interested in deploying electronic sensors and delivery vehicles that leave no trace of their existence after use, thus avoiding discovery and alleviating the need for device recovery.

There is more.

They could make spying undetected much easier.  I am not sure what use the material would have in building material unless it was used to sabotage a building.

Should Republicans go ahead and add Supreme Court Justices to head off Democrats

Washington Post: Some Democrats eye adding more justices to the Supreme Court to change its ideological bent The once-remote idea has gained the attention of liberals angered by the GOP push to remake the federal courts. Probably the easy way to defeat this court-packing scheme is for Trump to propose doing the same thing now.  It would lead to Democrat denunciations and claims that it would be wrong, thereby blowing up any attempt by them in the unfortunate event of Democrats winning a presidential election.

29 % of companies say they are unlikely to keep insurance after Obamacare

Conn Carroll: A new survey of 368 midsize to large companies found that 29% of them are considering terminating their active employee health care plans when Obamacare is full implemented in 2014. Only 71% of employers surveyed said they did not expect to drop their health coverage, while 20% said they did not know and 9% said they were planning to exit. The latest survey, conducted by Towers Watson, echoes an ealier survey by McKinsey & Co. finding that 30% of private-sector employers were planning to drop their employee health insurance coverage by 2014. When the Congressional Budget Office crunched Obamacare's spending numbers, they estimated that only 7% of employees currently covered by employer-sponsored plans would lose their plans. ... This means the cost of the health care fiasco will be hundreds of billions more than estimated by the CBO and Congressional Democrat. It is also clear that Obama's pledge that you could keep your health care plan if you wanted t

Bin Laden's concern about Zarqawi's remains

James Robbins: ... Bin Laden suggests that President Bush should allow Zarqawi’s body to be returned to his family in Jordan, but this is a matter that is up to the Jordanian government, which so far has not shown much interest in facilitating a homecoming. Bin Laden mocks King Abdullah II, calling him a Coalition minion, and asking “w hat scares you about Abu Musab after he’s dead? You know that his funeral, if allowed to happen, would be a huge funeral showing the extent of sympathy with the mujahedin.” A large crowd would definitely turn out, though most people would be on hand to demonstrate their anger and disgust. Last November’s hotel bombings in Amman , masterminded by Zarqawi, are still fresh in people’s memory, and mentioning them to Jordanians has the same visceral impact as memory of the 9/11 attacks does here. Jordan has adopted a zero-tolerance policy towards those who choose to mourn the country’s least favorite son, and four opposition members of parliament who paid con
