New Study Shows Marijuana Users Have Low Blood Flow To the Brain (eurekalert.org) 560

cold fjord writes: State level marijuana legalization efforts across the U.S. have been gaining traction driven by the folk wisdom that marijuana is both a harmless recreational drug and a useful medical treatment for many aliments. However, some cracks have appeared in that story with indications that marijuana use is associated with the development of mental disorders and the long-term blunting of the brain's reward system of dopamine levels. A new study has found that marijuana appears to have a widespread effect on blood flow in the brain. EurekAlert reports: "Published in the Journal of Alzheimer's Disease, researchers using single photon emission computed tomography (SPECT), a sophisticated imaging study that evaluates blood flow and activity patterns, demonstrated abnormally low blood flow in virtually every area of the brain studies in nearly 1,000 marijuana users compared to healthy controls, including areas known to be affected by Alzheimer's pathology such as the hippocampus. According to Daniel Amen, M.D., 'Our research demonstrates that marijuana can have significant negative effects on brain function. The media has given the general impression that marijuana is a safe recreational drug, this research directly challenges that notion. In another new study just released, researchers showed that marijuana use tripled the risk of psychosis. Caution is clearly in order.'"

California must be doing something right if the population has grown so much. People actually want to come here. Unlike the Republican South from where people are leaving in droves for Blue states.

Your assertion is factually incorrect. There is a statistically significant migration from blue states to red states. People are voting with their feet, but not in the direction you imply.

Slashdot Asks: Should The US Abolish The Electoral College? 1081

Last night as votes were still being counted, statistician and editor-in-chief for FiveThirtyEight Nate Silver pointed out that while Donald Trump has been elected president of the United States, "it's possible, perhaps even likely, that [Hillary Clinton] will eventually win the popular vote as more votes come in from California." We now know that she has indeed won the popular vote by a slim margin. American journalist Carl Bialik adds via Silver's blog: Hillary Clinton could still conceivably win the election -- or she could lose the national popular vote. But since both outcomes look unlikely, we should start preparing ourselves for the possibility of the second split between the national popular vote and the electoral vote in the last five presidential elections. A coalition of 11 sates with 165 electoral votes between them has agreed to an interstate compact that, once signed by states with a combined 270 or more electoral votes, would bind their electors to vote for the winner of the national popular vote -- in effect ending the Electoral College. New York just joined this week. It wasn't enough to affect this election, but maybe today's result will spur more states to join. The results of this election echo the 2000 results, where Democrat Al Gore narrowly won the popular vote, but George W. Bush won the White House. It brings into question whether or not the Electoral College should be abolished in favor of the popular vote. As a refresher, the Electoral College is comprised of electors that cast their votes for president. Each state has a set number of electors that is based on the state's population -- the candidate who wins the state's popular vote gets those electors. Technically, on Election Day, the American people are electing the electors who elect the president. The New York Times has a lengthy article describing how the Electoral College works, which you can view here.

I appreciate your sentiment, coward, I really do. I don't know if privacy settings are persisted through OS upgrades, and if it isn't then that is a bug.

That said: It takes fortitude to stand up, use your real name, identify your employer, and then talk about an unpopular feature in your employer's products. I choose to do so. If you are going to personally attack me for it please be so kind as to extend the same courtesies, Coward.

You asked for information, I provided it. Microsoft tells you what is in Telemetry. You want to see for yourself; I told you how. The "other bazillion sites" (your words) are listed in the second link I posted, as well as links for how to opt-in or opt-out.

Internally Microsoft is crushingly strict about privacy and data protection. I didn't realize that until I started working here and saw it for myself.

These are my own opinions, and not those of my employer.

Slashdot Asks: Is It Time To Dump Time Zones In Favor of Coordinated Universal Time? (nytimes.com) 598

Last Sunday, those of us in North America, Europe and some areas of the Middle East rolled back the clock an hour in accordance with Daylight Savings Time (DST). The tradition -- first imposed in Germany 100 years ago -- has been around for so long that many of us fail to question its significance. What is the importance of Daylight Savings Time? Is it still relevant in today's world? Is it time to dump time zones in general? James Gleick makes the case via the New York Times for switching to Coordinated Universal Time, or U.T.C.: When it's noon in Greenwich, Britain, let it be 12 everywhere. No more resetting the clocks. No more wondering what time it is in Peoria or Petropavlovsk. Our biological clocks can stay with the sun, as they have from the dawn of history. Only the numerals will change, and they have always been arbitrary. Some mental adjustment will be necessary at first. Every place will learn a new relationship with the hours. New York (with its longitudinal companions) will be the place where people breakfast at noon, where the sun reaches its zenith around 4 p.m., and where people start dinner close to midnight. ("Midnight" will come to seem a quaint word for the zero hour, where the sun still shines.) In Sydney, the sun will set around 7 a.m., but the Australians can handle it; after all, their winter comes in June. The question has been posed before, but given the timeliness of Daylight Savings Time, we think the question may evoke some new, heartfelt attitudes and beliefs: Is it time to dump time zones in favor of Coordinated Universal Time?

Submission + - SPAM: Nuclear weapon missing since 1950 'may have been found' 1

schwit1 writes: A commercial diver may have discovered a lost decommissioned US nuclear bomb off the coast of Canada.

Sean Smyrichinsky was diving for sea cucumbers near British Columbia when he discovered a large metal device that looked a bit like a flying saucer.

The Canadian Department of National Defence (DND) believes it could be a "lost nuke" from a US B-36 bomber that crashed in the area in 1950.

The government does not believe the bomb contains active nuclear material.

Submission + - 'Here Be Dragons': The 7 Most Vexing Problems in Programming

snydeq writes: 'It’s been said that the uncharted territories of the old maps were often marked with the ominous warning: “Here be dragons.” Perhaps apocryphal, the idea was that no one wandering into these unknown corners of the world should do so without being ready to battle a terrifying foe,' writes InfoWorld's Peter Wayner in a roundup of seven gnarly corners of the coding world worthy of large markers reading, 'Here be dragons.' 'Programmers may be a bit more civilized than medieval knights, but that doesn’t mean the modern technical world doesn’t have its share of technical dragons waiting for us in unforeseen places: Difficult problems that wait until the deadline is minutes away; complications that have read the manual and know what isn’t well-specified; evil dragons that know how to sneak in inchoate bugs and untimely glitches, often right after the code is committed.'

Submission + - Defense Distributed Requests Hearing on 3D Firearm Plans Over Freedom Of Speech (reason.com)

SonicSpike writes: In September, a three-judge panel of the 5th Circuit Court of Appeals denied a motion to enjoin the State Department from censoring the American organization Defense Distributed. The Department back in 2013 threatened them with prosecution for hosting computer files that instruct 3D printers to make a plastic pistol, one the company calls "The Liberator." Defense Distributed have since then complied with the department's demand.

Provocateur and author Cody Wilson, who runs the organization and built and fired the first 3D-printed plastic pistol, believes that State Department threats to treat hosting such files as the equivalent of exporting illegal munitions amount to a prior restraint violation of their First and Second Amendment rights. (The Second Amendment Foundation is also a plaintiff in the suit.)

Defense Distributed's legal team, including Alan Gura (who has won two substantial victories for the Second Amendment at the Supreme Court), filed on Friday a petition to the Fifth Circuit for an en banc rehearing (before the entire Court, not just a three-judge panel) of the injunction request.

The new filing's arguments, quoted and summarized:

"Never before has a federal appellate court declined to enjoin a content-based prior restraint on speech while refusing to consider the merits of a First Amendment challenge...The panel majority's novel decision contradicts a long line of established Supreme Court and circuit precedents governing constitutional claims and injunctive relief—including decisions of this and all other regional federal circuit courts of appeal."

Submission + - Clinton Had Uncleared Filipino Maid Print Emails, Handle Sensitive Documents (nypost.com) 13

An anonymous reader writes: The New York Post reveals that Hillary Clinton routinely had her emails forwarded so her immigrant Filipino maid who lacked a security clearance could print her emails from an iMac in Clinton's home, including ones that contained classified information. The maid also had access to the SCIF (sensitive compartmented information facility) built at Clinton's home so she could "securely" receive Top Secret information such as the presidential daily brief she received at times. The maid was expected to retrieve faxed information from the SCIF for Secretary Clinton. It appears that the maid was never interviewed by the FBI, nor was the computer seized or searched. One is left wondering, "Was email that hard to print in 2009?" Will the reinvigorated FBI investigation cover untrodden ground like this, or just serve as another white wash?
