MEMORY HOLE U.S. scientists have developed a memory wipe enzyme that can erase memories

forever

by: Isabelle Z.

Are there any bad memories in your life that you wish you could simply erase?

Researchers might have found a way to do exactly that thanks to the discovery of the enzyme

in the brain that plays a pivotal role in storing long-term memories.

They believe that this enzyme could be targeted in order to essentially wipe distressing memories

out of the minds of people suffering from post-traumatic stress disorder (PTSD).

However, like many things that sound too good to be true, this development is raising red

flags left and right.

Scientists have long known that creating new memories and storing old ones involve the

creation of proteins in the synapse, where two brain cells meet.

For this process to be successful, genes must be expressed in the nucleus of the cell, and

this is where a key enzyme can turn genes on or off as new memories are formed.

It�s also believed that this enzyme, which is known as ACSS2, plays a role in the memory

impairment that is seen in neurodegenerative disorders.

In the study, the researchers found that lowering ACSS2 levels in mice reduced the expression

of memory genes, thereby stopping the formation of long-term memories.

Mice who had reduced enzyme levels showed no interest in a ball they saw the previous

day, whereas those with normal levels of the enzyme were interested in the ball.

Now the researchers are hoping to use this knowledge to stop traumatic memories from

forming in people with PTSD simply by blocking the brain�s ACSS2.

This might sound like a good idea to those of us who are haunted by some sort of trauma,

but there�s also the potential for this to be used for more sinister reasons.

Another convenient form of mind control

For example, what�s to stop an agency like the CIA from erasing highly inconvenient memories

from people�s minds?

The police state could use it as a way to deal with people who it deems to be �anti-establishment.�

A journalist who uncovers damning evidence about something like vaccines or GMOs could

easily be made to forget that information before they are able to report on it.

The possibilities are as endless as they are disturbing.

Of course, there�s also the fact that some of our bad memories likely serve a very good

purpose.

If we erase our memories of mistakes we�ve made, for example, what will stop us from

repeating them later?

If you wiped the memory of being stalked by someone, the next time you encounter that

person, you might even invite them into your house!

This approach is also unnecessary if their stated goal is merely to help the traumatized

and there are no ulterior motives at play here.

PTSD sufferers can be helped with a number of techniques, such as healing touch with

guided imagery and cognitive-behavioral therapy.

Creating false memories

On the flip side of this coin, it�s also possible to give people memories of incidents

that never took place.

It�s hard to say which scenario is more frightening.

Psychologist Julia Shaw has demonstrated the ability to make a person remember committing

a crime they did not have a hand in, even going so far as to provide vivid details about

the imaginary event.

While it�s hard to imagine why a criminal psychologist would want to convince a patient

they did something they hadn�t, it does raise a lot of interesting questions.

If she can do it, it�s hardly a stretch to imagine that others, including law enforcement

and governmental agencies, also possess this capability.

If so, there really is nothing stopping them from using it to convince those who oppose

them or speak out against them that they committed a crime and lock them up.

The Truth About Gladiators and the Thumbs Up - Duration: 8:26.

Hello I'm Daven Hiskey, you're watching the Today I Found Out youtube channel, in the

video today, we're looking at the origin of the thumbs up gesture and whether it really

had anything to do with Roman Gladiators.

There are few hand gestures out there as well known or ubiquitous as the humble thumbs up.

But why is this seemingly innocuous gesture so widespread; how did it come to mean "everything

is okay" in so many cultures and where did it come from?

The commonly told origin is that it came from the Romans and their gladiatorial games: thumbs

up meant live and thumbs down meant die.

This is unequivocally false.

While it is true that in the days of gladiatorial combat in the Colosseum and the earlier (and

significantly larger) Circus Maximus, the audience could decide the fate of a fallen

gladiator with a simple hand gesture, this isn't typically depicted accurately and

has little to do with why thumbs up and thumbs down means what it does today.

The fate of a gladiator, in terms of whether the audience was voting for a kill, was decided

with what is known as "pollice verso", a Latin term which roughly translates to "turned

thumb".

More precisely what this means isn't known and there are no accounts that have survived

to this day that describe it in any real detail.

As such, we're unable to say for sure which way the thumb was supposed to be pointed if

the audience wanted a given gladiator to be killed or if they could just wave their thumbs

around at random, which it seems may well have been the case.

So that's voting for death, what about life?

The gesture to spare a given gladiator's life seems to have been neither a thumbs up

nor a thumbs down.

Instead, you had to hide your thumb inside your fist, forming a gesture known as pollice

compresso, "compressed thumb".

The reasons for this has been speculated to be twofold: first, it made the decision of

the crowd easier to discern, since it's easier to tell the difference between a thumbs

turned and a closed fist than a thumbs up and a thumbs down from a long ways away.

And two, the gestures themselves are thought to be largely symbolic of what they represented-

a pointed thumb represented the audience's desire for the victorious gladiator to deliver

his coup de grâce (stab the fallen foe), while a hidden thumb symbolised that they

wished for the gladiator to stay his blade, sheathing it much in the way they'd hidden

their thumbs.

Hence why it's thought "turned thumb" may well have been simply waving your thumb

around in the air, perhaps in a stabbing motion.

However, this fact is largely absent from pop culture representations, most notably

in the otherwise enjoyable 2000 movie, Gladiator, in which Joaquin Phoenix is shown giving a

defeated gladiator a thumbs down to signify that he wishes for him to be killed.

According to director Ridley Scott, that scene was inspired by a painting from 1872 called

"Pollice Verso".

The painting depicts a victorious gladiator standing over the lifeless body of his opponent

while a baying crowd jeers and delivers a tsunami of down-turned thumbs.

Scott stated of the painting, "That image spoke to me of the Roman Empire in all its

glory and wickedness.

I knew right then and there I was hooked."

That particular painting has been noted by historians as the catalyst for why the concept

of pollice verso is so poorly understood today by the masses.

What makes this fact so surprising is that the painter behind the piece, Jean-Léon Gérôme,

was a hugely respected historical artist who was internationally renowned for his "archaeologically

correct history paintings".

Gérôme has been described as a "learned classicist" and was famous for extensively

researching his pieces before putting brush to canvas.

For example, with "Pollice Verso" Gérôme studied actual pieces of armor from the ruins

of Pompeii so that the gladiators in his paintings looked authentic.

Gérôme's legendary attention to detail is probably the reason that his interpretation

of pollice verso was so widely accepted by academics and why it was so widely disseminated,

even after it was proven false.

As for what historians of his era thought, interpretations varied greatly from thumbs

up meaning kill and thumbs down meaning live (and vice versa), to hidden thumb in fist

meaning live and thumbs down meaning kill, and pretty much every variation therein.

Why Gérôme chose thumbs down isn't known, or even whether he meant it as is often interpreted-

"kill".

People predominantly interpreted the painting this way (and still do), but in truth there

is no evidence that this was what Gérôme was going for.

So, if the Romans aren't generally thought today to be the origin of the thumbs up gesture,

who was?

That isn't known precisely and we're left mostly with just guesses.

But it might surprise you that the mass-popularity of thumbs up / thumbs down, meaning as it

does today, is a fairly recent phenomenon, though gesturing with one's thumb is prevalent

in many cultures throughout much of history with varied meanings.

So what about some educated guesses as to the origin of the thumb gestures?

If you ask linguist anthropologist Joel Sherzer of the University of Texas, the gesture (meaning

something) likely pre-dates the Romans.

He went on to say of Europeans, "The dichotomy of up meaning 'positive' and down meaning

'negative' pervades the language and gesture systems of Europe…

The thumbs-up gesture probably originates from this contrast."

We can see evidence of this gesture in such images as the 1617 painting by Spanish artist

Diego Velázquez titled, The Lunch, though what the gesture meant precisely in this case

is open to interpretation.

As for a speculative theory that is a little more concrete, one of the more convincing

theories of the origin of the modern meaning of thumbs up comes from Desmond Morris'

1979 work, Gestures: Their Origins and Distribution.

He states that it derives from a custom prevalent in medieval times where people making a deal

would lick their thumbs and press them up against one another, rather like shaking hands

today.

It's theorised that over time this diluted to the act of simply sticking one's non-licked

thumb into the air to symbolise approval.

Whatever the case, at the least, we do know how the meaning was so widely popularised.

For this one, we need to fast-forward to much more recently in history- WWII.

During WWII, the thumbs up gesture was used extensively by American pilots as a shorthand

way of indicating to their ground crews that they were ready to fly.

It has been speculated that they got this from the Chinese, with specifically the Flying

Tiger brigade of American pilots based in China seemingly being the first (or among

the first) to popularly use the gesture, at least as far as photographic evidence from

the era seems to indicate.

To the Chinese at this time, the thumbs up gesture meant "number one" or "nice

job" depending on context.

(Why this is the case is up for debate.)

Whether it truly was adopted from the Chinese or some other source, the American pilot version

initially meant "I'm ready" or "good to go".

From here, things become much more clear.

This "ready" meaning soon evolved into a simple, all-encompassing way to indicate

that everything was okay in situations where verbal cues weren't possible or advisable.

It was also picked up by the rest of the American military who proceeded to make extensive use

of the gesture during their many campaigns across Europe; in the process, it was picked

up by the locals and soldiers from other militaries.

From there, the thumbs up symbol temporarily declined somewhat in popularity by the 1960s,

but made a huge comeback thanks to Hollywood, and particularly Fonzie and his two thumbs

up "aaaaaaaaay" gesture in Happy Days which debuted in 1974.

Today, thanks to the widespread use of thumbs up meaning "like" or "good" and thumbs

down meaning the opposite on numerous popular websites and apps, this meaning of the hand

gesture is likely not going anywhere for the foreseeable future.

Bonus Fact:

As we alluded to previously, there are several places on Earth where a thumbs up is considered

a grave insult.

For example, in places like Iraq and Greece, sticking up your thumb is akin to saying "shove

it up your a**".

It also meant this in Australia before WWII, but afterward switched to the modern meaning

thanks to the dissemination of the gesture throughout the Allied military.

The exact reasoning behind this meaning, as with many gestures, isn't clear, but it's

believed to be representative of the action that would be required for you to act out

the insult itself.

In fact, in some of these cultures that interpret it this way, an up and down movement often

accompanies the gesture to make the meaning perfectly clear.

On that note, when American troops first started being stationed in Iraq, some reported being

greeted by civilians offering a thumbs up, with the soldiers (and many in the media)

interpreting it as most Westerners would, all the while not realising the obscene connotations

it has in that country.

The Truth About Gladiators and the Thumbs Up - Duration: 8:26.

Hello I'm Daven Hiskey, you're watching the Today I Found Out youtube channel, in the

video today, we're looking at the origin of the thumbs up gesture and whether it really

had anything to do with Roman Gladiators.

There are few hand gestures out there as well known or ubiquitous as the humble thumbs up.

But why is this seemingly innocuous gesture so widespread; how did it come to mean "everything

is okay" in so many cultures and where did it come from?

The commonly told origin is that it came from the Romans and their gladiatorial games: thumbs

up meant live and thumbs down meant die.

This is unequivocally false.

While it is true that in the days of gladiatorial combat in the Colosseum and the earlier (and

significantly larger) Circus Maximus, the audience could decide the fate of a fallen

gladiator with a simple hand gesture, this isn't typically depicted accurately and

has little to do with why thumbs up and thumbs down means what it does today.

The fate of a gladiator, in terms of whether the audience was voting for a kill, was decided

with what is known as "pollice verso", a Latin term which roughly translates to "turned

thumb".

More precisely what this means isn't known and there are no accounts that have survived

to this day that describe it in any real detail.

As such, we're unable to say for sure which way the thumb was supposed to be pointed if

the audience wanted a given gladiator to be killed or if they could just wave their thumbs

around at random, which it seems may well have been the case.

So that's voting for death, what about life?

The gesture to spare a given gladiator's life seems to have been neither a thumbs up

nor a thumbs down.

Instead, you had to hide your thumb inside your fist, forming a gesture known as pollice

compresso, "compressed thumb".

The reasons for this has been speculated to be twofold: first, it made the decision of

"kill".

People predominantly interpreted the painting this way (and still do), but in truth there
