Psychic computer shows your thoughts on screen!

Psychic computer shows your thoughts on screen


Scientists have discovered how to “read” minds by scanning brain activity and reproducing images of what people are seeing — or even remembering.
Researchers have been able to convert into crude video footage the brain activity stimulated by what a person is watching or recalling.
The breakthrough raises the prospect of significant benefits, such as allowing people who are unable to move or speak to communicate via visualisation of their thoughts; recording people’s dreams; or allowing police to identify criminals by recalling the memories of a witness.
However, it could also herald a new Big Brother era, similar to that envisaged in the Hollywood film Minority Report, in which an individual’s private thoughts can be readily accessed by the authorities.
Jack Gallant and Shinji Nishimoto, two neurologists from the University of California, Berkeley, last year managed to correlate activity in the brain’s visual cortex with static images seen by the person. Last week they went one step further by revealing that it is possible to “decode” signals generated in the brain by moving scenes.
In an experiment which has yet to be peer reviewed, Gallant and Nishimoto, using functional magnetic resonance imaging (fMRI) technology, scanned the brains of two patients as they watched videos.
A computer programme was used to search for links between the configuration of shapes, colours and movements in the videos, and patterns of activity in the patients’ visual cortex.
It was later fed more than 200 days’ worth of YouTube internet clips and asked to predict which areas of the brain the clips would stimulate if people were watching them.
Finally, the software was used to monitor the two patients’ brains as they watched a new film and to reproduce what they were seeing based on their neural activity alone.
Remarkably, the computer programme was able to display continuous footage of the films they were watching — albeit with blurred images.
In one scene which featured the actor Steve Martin wearing a white shirt, the software recreated his rough shape and white torso but missed other details, such as his facial features.
Another scene, showing a plane flying towards the camera against a city skyline, was less successfully reproduced. The computer recreated the image of the skyline but omitted the plane altogether.
“Some scenes decode better than others,” said Gallant. “We can decode talking heads really well. But a camera panning quickly across a scene confuses the algorithm.
“You can use a device like this to do some pretty cool things. At the moment when you see something and want to describe it to someone you have to use words or draw it and it doesn’t work very well.
“You could use this technology to transmit the image to someone. It might be useful for artists or to allow you to recover an eyewitness’s memory of a crime.”
Such technology may not be confined to the here and now. Scientists at University College London have conducted separate tests that detect, with an accuracy of about 50%, memories recalled by patients.
The discoveries come amid a flurry of developments in the field of brain science. Researchers have also used scanning technology to measure academic ability, detect early signs of Alzheimer’s and other degenerative conditions, and even predict the decision a person is about to make before they are conscious of making it.
Such developments may have controversial ramifications. In Britain, fMRI scanning technology has been sold to multinational companies, such as Unilever and McDonald’s, enabling them to see how we subconsciously react to brands.
In America, security agencies are researching the use of brain scanners for interrogating prisoners, and Lockheed Martin, the US defence contractor, is reported to have studied the possibility of scanning brains at a distance.
This would allow an individual’s thoughts and anxieties to be examined without their knowledge in sensitive locations such as airports.
Russell Foster, a neuroscientist at Oxford University, said rapid advances in the field were throwing up ethical dilemmas.
“It’s absolutely critical for scientists to inform the public about what we are doing so they can engage in the debate about how this knowledge should be used,” he said.
“It’s the age-old problem: knowledge is power and it can be used for both good and evil.”

Drugs, Rap and Murder..

On April 10, 2002, 25-year-old Singleton murdered Tynisha Ysais in her Los Angeles, California apartment.[3] Her boyfriend Thomas Moore testified that he and Singleton spent the evening prior to the murder smoking PCP, also known as "angel dust."
The victim was found in her apartment by her friend Alisa Allen. Her chest had been torn open and a three-inch blade was found broken off in her shoulder blade. Tooth marks were found on her face and on her lungs, which had been torn from her chest. Eyewitnesses reported that when Singleton was picked up by police, he was naked, covered in blood, standing in the middle of the street and staring at the sky. A medical examination performed shortly after his capture found human flesh in his stomach which was not his own.[1]
On November 7, 2003, Singleton was sentenced to life in prison.[3] He had been convicted of murder and aggravated mayhem the previous June after pleading not guilty by reason of insanity at the time of the murder. The court ruled that his intoxication and plea of insanity were not satisfactory reasons for committing the crime.
In 2004, Stress Free Ent. and Black Market Activities released a solo LP on behalf of Singleton, It's All Bad. Features included Killa Tay, C-Bo, Lil Keke, Roger Troutman II and Too $hort.
Ysais' mother, Carolyn Stinson, filed a wrongful death lawsuit against Black Market Activities, Singleton's record label. The label, in similar fashion, has put out albums for X-Raided while he was awaiting trial and eventually convicted of murder (Xorcist, Unforgiven, Vol. 1, etc.). The suit charged that the label had provided Singleton with drugs "to encourage [him] to act out in an extreme violent manner so as to make him more marketable as a 'gangsta rap' artist."[1]
"Part of what makes a Gangsta Rap artist marketable is the fact that the artist is a current ongoing participant in violent gang activities," the lawsuit said.[1]
He is currently serving his life sentence at California State Prison, Los Angeles County in Lancaster, California.

Earthquakes in Divers Places..

CNN-- Four tropical cyclones, two major earthquakes with accompanying tsunamis, all occurring around the Western Pacific and Southern Asia within one day.

The goal for scientists is to provide warnings ahead of these deadly earthquakes.


So much activity in the same portion of the world, how unusual is something like this, and could they be related?
According to CNN meteorologist and weather producer Brandon Miller, this is certainly not unprecedented as far as tropical systems go. "September represents the peak of tropical activity around the world, and the Western Pacific sees more tropical cyclones each year than anywhere on the globe, so even having four systems active at the same time is not incredibly unusual," he said.
Perhaps the more intriguing events are the two major earthquakes; the 8.0 magnitude near Samoa Tuesday followed by the 7.6 magnitude in western Indonesia.
The epicenters of the two tremors are about 4,700 miles (7,600 km) apart, but the U.S. Geological Survey has declined to say whether the two quakes were linked.
Miller said: "We only see between five and 10 earthquakes of this magnitude on average around the globe each year, so to see them in the same general region within 18 hours seems to be quite a coincidence."
The earth is covered with a relatively thin set of tectonic plates that make up the outer shell of the planet -- known as the lithosphere. The plates are all connected and constantly moving, creating pressure and tension along their boundaries. Earthquakes occur when this tension reaches a critical maximum, and similar to a rubber band that has been stretched to its limits, it will snap.
Don't Miss
"It seems to reason that a large earthquake in one location could provide the extra force needed in another nearby location, to stretch that rubber band to the breaking point, thus triggering another earthquake," Miller said.
Another piece to the puzzle: Both of these earthquakes occurred along opposite ends of the same tectonic plate, the Australian plate. The Australian plate borders the Pacific plate to the East (the Samoan quake occurred along this boundary), while on the Western side, it borders the Eurasian plate (where the Indonesia quake occurred).
Several of these plates surround the Pacific Ocean basin forming an arc of quake sites and active volcanoes known as the "Ring of Fire." This ring is actually a 40,000 km horseshoe shape, where most of the Earth's active volcanoes above sea level and most of the world's earthquakes are located.
So did the Samoan quake help to trigger the Indonesian quake?
"While we cannot say for sure, it does seem plausible," said Miller. "Scientists will certainly study these events and try to find any connection that could tie them together, with the ultimate goal of some day being able to provide warnings ahead of these deadly earthquakes."
The biggest earthquake ever measured -- magnitude 9.5 -- occurred within the ring along the coast of Chile. It created a tsunami that killed around 2,000 people before it radiated outwards, killing 61 people in Hawaii and 122 in Japan.
In December 2004, an earthquake measuring at least 9.0 struck off the coast of the northern tip of Indonesia's Sumatra island, triggering a major tsunami in the Indian Ocean that killed more than 200,000 people in 11 countries. The impact on Indonesia, Thailand and Sri Lanka was particularly devastating.
The most famous volcanic eruption in recent history was Krakatoa, Indonesia in August 1883. It generated 40-meter tsunamis that smashed into islands nearby, destroying hundreds of villages and killing tens of thousands of people.

Jesus said that there would be dramatic increases weather related and earth related catastrophies before His return to Judge the Earth, we see this evidenced everyday in the local media. Please when you see or read about disasters, pray for those suffering in them, pray for the children, pray for His return to be speedy.
