U.S. pilot was ordered to shoot down UFO
By Peter Griffiths
LONDON (Reuters) – Two U.S. fighter planes were scrambled and ordered to shoot down an unidentified flying object (UFO) over the English countryside during the Cold War, according to secret files made public on Monday.
One pilot said he was seconds away from firing 24 rockets at the object, which moved erratically and gave a radar reading like "a flying aircraft carrier."
The pilot, Milton Torres, now 77 and living in Miami, said it spent periods motionless in the sky before reaching estimated speeds of more than 7,600 mph.
After the alert, a shadowy figure told Torres he must never talk about the incident and he duly kept silent for more than 30 years.
His story was among dozens of UFO sightings in defense ministry files released at the National Archives in London.
"He threatened me with a national security breach if I breathed a word about it to anyone," he said.

And here's another interesting article recently published by CBC news about scientists finding how to erase select memories in mice:
Scientists find way to erase select memories in mice
In a finding worthy of a science fiction novel, U.S. scientists reported they could selectively erase specific memories in mice without affecting recall of other events.
Research published in the journal Neuron found that the manipulation of a type of protein in the brain can wipe out certain memories in the brains of mice.
The study elicited memory loss by manipulating the activity of a protein called alpha-CaM kinase II, which is involved in learning and memory.
The study said it may be possible in the future to develop a pill that wipes out traumatic memories, like war-related ones, but lead researcher Joe Tsien of the Medical College of Georgia cautioned against the wisdom of the benefits of erasing a person's bad memories.
