Scientist close in on the cause of Alzheimer

 Epoch Times:

...

Scientists at the University of California—Riverside, in recent findings, said that the key to understanding Alzheimer’s may have to do with “tau” proteins that likely caused neurofibrillary tangles—which are found in the brains of Alzheimer’s patients. Previously, researchers have suggested that amyloid plaques, which are a buildup of amyloid peptides, may also be the cause.

Both amyloid plaques and the neurofibrillary tangles are two critical indicators that doctors look for when trying to diagnose Alzheimer’s.

“Roughly 20 percent of people have the plaques, but no signs of dementia,” said UCR Chemistry Professor Ryan Julian in a release. “This makes it seem as though the plaques themselves are not the cause.”

Researchers focused on the different structures a single molecule can manufacture, known as an isomer.

While they have made some discoveries in this area they do not appear to have a solution to the problem at this point.  There is more work to be done to find a way to straighten out the tangles.

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...

Is the F-35 obsolete?

Headline USA: Pentagon Fires Back after Musk Calls Its Most Expensive Project ‘Obsolete’ 'Yeah, as I'm sure you can appreciate, Mr. Musk is, currently, a private citizen, I'm not going to make any comments about what a private citizen may have to say about the F-35....'   ... ... Drones appear to be replacing jets for many operations.  The Russia-Ukraine war is an example of that.  Drones are often hard to detect and can be used for intelligence operations as well as for attacking enemy targets.  It would not surprise me to see drones engaging other drones in combat.  They also cost much less than manned fighters.
