GOOD MORNING LOVELY UFOCASEBOOKERS
Repeating fast radio bursts recorded for the first time
Deep-space blasts came again and again and again
By Christopher Crockett 1:00pm, March 2, 2016
Fast radio bursts from deep space have never been seen to repeat — until now.
Ten blasts of radio waves recorded last May and June all come from the same direction, researchers report online March 2 in Nature. So did a signal detected in 2012, say Laura Spitler, an astrophysicist at the Max Planck Institute for Radio Astronomy in Bonn, Germany, and colleagues. All 11 signals were detected at the Arecibo Observatory in Puerto Rico.
Fast radio bursts, or FRBs, last a few milliseconds and, except for one, all appear to originate in other galaxies (SN: 8/9/14, p. 22). For the repeater, each of the signals encountered the same amount of intergalactic plasma, meaning they traveled the same distance. That shared feature makes an ironclad case for a common source, says Duncan Lorimer, an astrophysicist at West Virginia University in Morgantown and co-discoverer of the first FRB, reported in 2007. The question now is what fraction of sources repeat, he says. There may be multiple classes of FRBs, with some recurring and some not, each triggered by something different.
Explanations for what causes FRBs include colliding stellar cores, overzealous pulsars and the collapse of obese neutron stars. A repeating signal rules out one-off scenarios such as collisions. More likely sources are radio eruptions from various types of neutron stars, such as pulsars and magnetars. Pulsars emit a steady beat of radio waves, but some young pulsars, such as the nearby Crab pulsar, occasionally blast out vigorous pulses. Radio telescopes could detect such large blasts from another galaxy, Spitler says.
With a known repeater, a facility like the Very Large Array near Socorro, N.M., could stare at the same patch of sky, wait for the next eruption and identify the host galaxy (SN Online: 2/26/16). “It’s a wake-up call that there’s a lot we can do with existing FRBs,” Lorimer says.

Bigfoot Sightings Abound In Early Rim Country History
Things that go ‘snap’ in the night
By Chuck Jacobs March 1, 2016
This is an occasional series about Bigfoot/Sasquatch activity in the Rim Country.
A while ago someone posed a question about why there aren’t any Sasquatch stories from any of the early Rim Country pioneer families. The short answer is… there are. There are not as many as we might think there would be, but there are a few.
Even long before we came along, the Native American tribes all had legends of “the hairy man,” who lived deep in the forests and came out only at night. These beliefs and legends persist to this day among tribal traditionalists. I had the distinct honor and privilege last year of spending some time with some of these folks, who trusted me enough to be completely open in telling me about their Sasquatch-related knowledge and what they believe… stuff that has been handed down over many generations. It was an experience that I will always remember.
One of the earliest stories I have found from the first Rim Country pioneers was a daytime encounter by David Gowan, who is credited with the “discovery” of the Tonto Natural Bridge. Gowan spent his later years living in a remote cabin on a mining claim along upper Deer Creek, in the Mazatzal Mountains west of the present Deer Creek Village community. He actually died up there in 1925, and is buried next to the Deer Creek hiking trail, a few miles up from the trailhead. As the story goes, Gowan was walking the trail down off the mountain, leading a string of pack burros with ore from his mine, when he came upon two very large “mountain apes” blocking the trail. Gowan and the creatures stood facing each other for awhile, and when they appeared unwilling to move Gowan simply led his burros off-trail, making a wide circle around the creatures, and continued on his way. Later, after Gowan died, people using his old cabin reported being screamed at and having the cabin pelted with rocks during the night, which is common Sasquatch territorial behavior. Apparently a family group had settled in the area, and didn’t appreciate the human visitors. Gowan’s old cabin burned in the Willow Fire in 2004, and subsequent flash floods have virtually destroyed the once-idyllic site, leaving only a small part of the stone foundation still visible.
You noticed that in the story above I used the term mountain apes. That’s what they were called in early Arizona. The name Sasquatch was coined by a schoolteacher in British Columbia in 1927, and the now-famous Bigfoot name was made up by a newspaper reporter in northern California in 1958. So they were mountain apes… that was until the famous incident in 1944 or 1945 that introduced the Mogollon Monster name.
The best account that I have found of the Mogollon Monster incident was written by the late author Don Davis, who was actually one of the Boy Scouts who was there and witnessed it all. In a very short synopsis of the incident… a group of Scouts was camping along Tonto Creek, probably in the present-day Bear Flat area, when they were terrorized during the night by a large, foul-smelling, hair-covered creature. The creature stood on two legs, walked like a person, and ransacked their food supply, eating all of their food, including even the pancake flour. None of the Scouts or their adult leaders were harmed, although they were all badly frightened by the encounter. The local folks around here had never heard of the term Sasquatch, and the name Bigfoot hadn’t been invented yet, so they called the creature the Mogollon Monster.
Knowing what we know now about Sasquatch behavior, we theorize that this could have simply been a territorial display, or it may have been an old outcast individual who was living as a solitary wanderer and was having difficulty finding enough food to eat. Hungry and desperate, it came into the camp and stole the humans’ food. Either way, it is very fortunate that none of the Scouts or their leaders were killed or injured.
While looking to collect stories from the early days of Rim Country, I asked local author and historian Jinx Pyle if he knew of any mountain ape stories that I would be interested in. Although I expected him to not take the question seriously, and maybe even laugh at me, he actually gave me a very straight answer. (Thanks, Jinx, I appreciated that.) He told me that he had actually been asked that question before, and he really had never heard of any stories like that from the early days. I asked him if he thought that maybe the early pioneer folks, if they did have an encounter, would have simply not talked about it, afraid that other people would ridicule them or accuse them of making the story up. He told me that the pioneer mind-set was not that way, and if one of them would have run across such an animal, they would have “shot it, skinned it, nailed the hide to the side of the barn, and told everyone they knew.” That makes sense to me, and the Sasquatches probably figured that out too… and stayed well away from the rifle-toting humans. That probably accounts, at least in part, for the lack of encounter stories from that time period. Even today, Sasquatches stay well away from humans with big guns, which is why we so seldom hear of encounters involving hunters.
If you would like more information on David Gowan, Google “David Gowan Tonto Natural Bridge,” where you will find an excellent June 10, 2008 article from the Payson Roundup, written by Stan Brown.
If you would like to read the late Don Davis’ complete story of the Mogollon Monster incident, Google “Mogollon Monster Don Davis.” You can find it there.

It is fascinating to think about how this technology might evolve over the next 1,000 years.....(If we don't kill ourselves off in the meantime.)
Monkeys drive wheelchairs using only their thoughts
Date: March 3, 2016 Source: Duke Health
Neuroscientists at Duke Health have developed a brain-machine interface (BMI) that allows primates to use only their thoughts to navigate a robotic wheelchair.
The BMI uses signals from hundreds of neurons recorded simultaneously in two regions of the monkeys' brains that are involved in movement and sensation. As the animals think about moving toward their goal -- in this case, a bowl containing fresh grapes -- computers translate their brain activity into real-time operation of the wheelchair.
The interface, described in the March 3 issue of the online journal Scientific Reports, demonstrates the future potential for people with disabilities who have lost most muscle control and mobility due to quadriplegia or ALS, said senior author Miguel Nicolelis, M.D., Ph.D., co-director for the Duke Center for Neuroengineering.
"In some severely disabled people, even blinking is not possible," Nicolelis said. "For them, using a wheelchair or device controlled by noninvasive measures like an EEG (a device that monitors brain waves through electrodes on the scalp) may not be sufficient. We show clearly that if you have intracranial implants, you get better control of a wheelchair than with noninvasive devices."
Scientists began the experiments in 2012, implanting hundreds of hair-thin microfilaments in the premotor and somatosensory regions of the brains of two rhesus macaques. They trained the animals by passively navigating the chair toward their goal, the bowl containing grapes. During this training phase, the scientists recorded the primates' large-scale electrical brain activity. The researchers then programmed a computer system to translate brain signals into digital motor commands that controlled the movements of the wheelchair.
As the monkeys learned to control the wheelchair just by thinking, they became more efficient at navigating toward the grapes and completed the trials faster, Nicolelis said.
In addition to observing brain signals that corresponded to translational and rotational movement, the Duke team also discovered that primates' brain signals showed signs they were contemplating their distance to the bowl of grapes.
"This was not a signal that was present in the beginning of the training, but something that emerged as an effect of the monkeys becoming proficient in this task," Nicolelis said. "This was a surprise. It demonstrates the brain's enormous flexibility to assimilate a device, in this case a wheelchair, and that device's spatial relationships to the surrounding world."
The trials measured the activity of nearly 300 neurons in each of the two monkeys. The Nicolelis lab previously reported the ability to record up to 2,000 neurons using the same technique. The team now hopes to expand the experiment by recording more neuronal signals to continue to increase the accuracy and fidelity of the primate BMI before seeking trials for an implanted device in humans, he said.
In addition to Nicolelis, study authors include Sankaranarayani Rajangam; Po-He Tseng; Allen Yin; Gary Lehew; David Schwarz; and Mikhail A. Lebedev.
The National Institutes of Health (DP1MH099903) funded this study. The Itau Bank of Brazil provided research support to the study as part of the Walk Again Project, an international non-profit consortium aimed at developing new assistive technologies for severely paralyzed patients.
