Ecstasy damages your brain

A new study, to be published in the journal Human Psychopharmacology: Clinical and Experimental [Authors Keith Laws and Joy Kokkalis from the University of Hertfordshire] shows that the drug ecstasy [MDMA] moderate to markedly damages both short and long-term memory.

The study was a meta-analysis.

Verbal memory appeared to be disproportionately affected compared to visual memory.

Another brand new study, published in the Archives of General Psychiatry, shows that even a first low cumulative dose of Ecstasy is associated with damaged verbal memory ability. [Ref. 1]

According to another recent meta-analysis, Ecstasy use is associated with multiple neurocognitive deficits: [Ref 2]

  • attention/concentration
  • verbal and nonverbal learning and memory
  • psychomotor speed and executive systems

Mini-Mystery by Stan Smith

June 20th, 2007

Thanks to Stan Smith for the following mini-mystery story, Murder in a London Flat. Stan Smith has written three books of Stanwick mini-mysteries that have been published in nine languages. He also produces a free Monthly MysteryGram with an original mini-mystery in each issue. To learn more about mini-mysteries, or to subscribe to the Monthly MysteryGram, you can visit www.stanwick-mini-mysteries.com.

MURDER IN A LONDON FLAT

Lord Calinore was gunned down in his London flat by a burglar, who
then ransacked the flat. The case was placed in the capable hands of Inspector Gilbert Bodwin of Scotland Yard. Bodwin’s investigation revealed that one man had planned the crime, another had carried it out, and a third had acted as lookout.

Bodwin discussed the case at length one evening over dinner at his club with an old friend, Thomas P. Stanwick, the amateur logician visiting from America.

“It’s quite a case,” Stanwick remarked. “Any suspects?”

Bodwin sliced his roast beef. “Yes indeed. Four. We have conclusive

evidence that three of those four were responsible for the crime.”

“Really! That’s remarkable progress. What about the fourth?”

“He had no prior knowledge of the crime and is completely innocent. The problem is that we’re not sure which of the four are the planner, the gunman, the lookout, and the innocent bystander.”

“I see.” Stanwick took more Yorkshire pudding. “What do you know about them at this point?”

“Well, the names of the four are Merrick, Cross, Llewellyn, and
Halifax. Halifax and Cross play golf together every Saturday. They’re an odd pair! Halifax can’t drive, and Cross has been out of Dartmoor Prison for only a year.”

“What was he in for?”

“Forgery. We know that Merrick and Halifax kept the flat under the surveillance for several days just before the day the crime was committed, the 17th. Llewellyn and Merrick, with their wives, had dinner together on the Strand on the 12th.”

“An interested compilation,” said Stanwick, “but hardly conclusive. Is that all of it?”

“Not quite. We know that the gunman spent the week before the crime in Edinburgh, and that the innocent bystander was acquainted with the planner and the gunman, but not with the lookout.”

“That’s very helpful,” said Stanwick with a smile. “Bodwin, your case
is complete!”

WHO WERE THE PLANNER, THE GUNMAN, AND THE LOOKOUT?

 

Will unmask submitted answers in a day. Thanks.

Here is a mask of Charlie Chaplin that rotates. Notice that, no matter how hard you try, the hollow and concave rear of the mask eventually becomes a convex golden face that spins counterclockwise. Pretty cool, give it a try:

Here’s another great optical illusion that will play major tricks on your mind. And if you haven’t seen some of Felice Varini’s work yet, check out this brain art.
