With the number of beheadings as the Sunni Ex Sadam troops and leaders now IS did during and documented from gassing kurds to putting prisoners in plastic shredders..these kinds of opportunities will multiply and continue to present themselves to any of the many snipers working out there. I wondered about it coming from the Beacon.. but my old friend was a navy seal and told me many a story of the one bullet one brain philosophy..they were good then and likely even better now..so it sounds quite about right at my end.. I am certain they were at the right place at the right time. I will give them a pass..we do have good guys left..and luck was on their side this time. I wont be cheering if they assassinate Assad..anywho well done..RIP the ones they could not save.

Hackers Cut a Corvette’s Brakes Via a Common Car Gadget
Car hacking demos like last month’s over-the-internet hijacking of a Jeep have shown it’s possible for digital attackers to cross the gap between a car’s cellular-connected infotainment system and its steering and brakes. But a new piece of research suggests there may be an even easier way for hackers to wirelessly access those critical driving functions: Through an entire industry of potentially insecure, internet-enabled gadgets plugged directly into cars’ most sensitive guts.
At the Usenix security conference today, a group of researchers from the University of California at San Diego plan to reveal a technique they could have used to wirelessly hack into any of thousands of vehicles through a tiny commercial device: A 2-inch-square gadget that’s designed to be plugged into cars’ and trucks’ dashboards and used by insurance firms and trucking fleets to monitor vehicles’ location, speed and efficiency. By sending carefully crafted SMS messages to one of those cheap dongles connected to the dashboard of a Corvette, the researchers were able to transmit commands to the car’s CAN bus—the internal network that controls its physical driving components—turning on the Corvette’s windshield wipers and even enabling or disabling its brakes.
“We acquired some of these things, reverse engineered them, and along the way found that they had a whole bunch of security deficiencies,” says Stefan Savage, the University of California at San Diego computer security professor who led the project. The result, he says, is that the dongles “provide multiple ways to remotely…control just about anything on the vehicle they were connected to.”
In the video below, the researchers demonstrate their proof-of-concept attacks on a 2013 Corvette, messing with its windshield wipers and both activating and cutting its brakes. Though the researchers say their Corvette brake tricks only worked at low speeds due to limitations in the automated computer functions of the vehicle, they say they could have easily adapted their attack for practically any other modern vehicle and hijacked other critical components like locks, steering or transmission, too.

Astronomers find 'teeny supermassive black hole'
University of Michigan astronomers have found the smallest black hole ever observed in the centre of a galaxy
By Sarah Knapton, Science Editors 9:08AM BST 12 Aug 2015
In a dwarf, disc galaxy 340 million light years away, University of Michigan astronomers have found the smallest black hole ever observed in the centre of a galaxy.
At just 50,000 times the mass of the sun, it's more than two times smaller than any other known object of its kind. It's a full 100,000 times less massive than the largest black holes at the heart of other galaxies.
"In a sense, it's a teeny supermassive black hole," said Elena Gallo, assistant professor of astronomy in the U-M College of Literature, Science, and the Arts.
However despite its diminutive size it appears to be is consuming material at a rate similar to active black holes in much more massive galaxies.
Black holes come in two types. The "stellar mass" variety have the mass of several suns. They form when the largest stars die and collapse. The other "supermassive" kind is typically at least 100,000 times the mass of the sun.
Every large galaxy, including our own Milky Way, is believed to have a supermassive black hole at its core. But the recently discovered object is one of the first to be identified in a dwarf galaxy.
And because the dwarf galaxy, called RGG 118, is so small, it's unlikely that it has ever merged with other galaxies, so it gives researchers a window to a younger universe. Larger galaxies are thought to have grown through mergers.
"These little galaxies can serve as analogs to galaxies in the earlier universe," said Vivienne Baldassare, a U-M doctoral student and first author of a paper on the results published today in the Astrophysical Journal Letters. "For galaxies like our Milky Way, we don't know what it was like in its youth.
"By studying how galaxies like this one are growing and feeding their black holes and how the two are influencing each other, we could gain a better understanding of how galaxies were forming in the early universe."
As is the case in most present-day galaxies, the Milky Way's black hole is dormant. Young or small galaxies like RGG 118 have active nuclei that are still in the process of swallowing stars, dust and gas. During this tumultuous time in galaxies' history, the central black hole helps to shape the galaxy.
To make the observations, the team used NASA's Chandra X-ray Observatory and the 6.5-meter Clay Telescope in Chile. RGG 118 was originally found through the Sloan Digital Sky Survey.
Researchers figured out the mass of the black hole by studying the motion of the gas near the centre of the galaxy using visible light data from the Clay Telescope. They used the Chandra data to figure out the brightness of material around the black hole in the X-ray band.
The X-ray luminosity tells astronomers the rate at which the black hole is taking in matter. RGG 118 is consuming material at 1 percent the maximum rate, which matches the properties of other supermassive black holes.
"This little supermassive black hole behaves very much like its bigger, and in some cases much bigger, cousins," said co-author Amy Reines, a Hubble fellow in the U-M Department of Astronomy. "This tells us black holes grow in a similar way no matter what their size."
Astronomers don't yet understand how supermassive black holes form. Some hypothesize that giant clouds of gas serve as their seeds. Others believe they descend from gargantuan stars about 100 times the mass of the sun.
“It might sound contradictory, but finding such a small, large black hole is very important,” said Vivienne Baldassare of the University of Michigan in Ann Arbor, first author of a paper on these results published in the Astrophysical Journal Letters. “We can use observations of the lightest supermassive black holes to better understand how black holes of different sizes grow.”
Researchers will continue to look for other supermassive black holes that are comparable in size or even smaller than the one in RGG 118 to help decide which of the models is more accurate and refine their understanding of how the objects grow.

Mystery Deepens: Matter and Antimatter Are Mirror Images
by Charles Q. Choi, Live Science Contributor August 12, 2015

Matter and antimatter appear to be perfect mirror images of each other as far as anyone can see, scientists have discovered with unprecedented precision, foiling hope of solving the mystery as to why there is far more matter than antimatter in the universe.
Everyday matter is made up of protons, neutrons or electrons. These particles have counterparts known as antiparticles — antiprotons, antineutrons and positrons, respectively — that have the same mass but the opposite electric charge. (Although neutrons and antineutrons are both neutrally charged, they are each made of particles known as quarks that possess fractional electrical charges, and the charges of these quarks are equal and opposite to one another in neutrons and antineutrons.)
The known universe is composed of everyday matter. The profound mystery is, why the universe is not made up of equal parts antimatter, since the Big Bang that is thought to have created the universe 13.7 billion years ago produced equal amounts of both. And if matter and antimatter appear to be mirror images of each other in every respect save their electrical charge, there might not be much any of either type of matter left — matter and antimatter annihilate when they encounter each other.
Checking charge parity Theoretical physicists suspect that the extraordinary contrast between the amounts of matter and antimatter in the universe, technically known as baryon asymmetry, may be due to some difference between the properties of matter and antimatter, formally known as a charge-parity, or CP symmetry violation. However, all the known effects that lead to violations of CP symmetry fail to explain the vast preponderance of matter over antimatter.
Potential explanations behind this mystery could lie in differences in the properties of matter and antimatter — for instance, perhaps antiprotons decay faster than protons. If any such difference is found, however slight, "this will of course lead to dramatic consequences for our contemporary understanding of the fundamental laws of physics," study lead author Stefan Ulmer, a particle physicist at Japan's Institute of Physical and Chemical Research (RIKEN), told Live Science.
In the most stringent test yet of differences between protons and antiprotons, scientists investigated the ratio of electric charge to mass in about 6,500 pairs of these particles over a 35-day period. To keep antimatter and matter from coming into contact, the researchers trapped protons and antiprotons in magnetic fields. Then they measured how these particles moved in a cyclical manner in those fields, a characteristic known as their cyclotron frequency, which is proportional to both the charge-to-mass ratio of those particles and the strength of the magnetic field. Perfect mirror images The scientists found the charge-to-mass ratio of protons and antiprotons "is identical to within just 69 parts per trillion," Ulmer said in a statement. This measurement is four times better than previous measurements of this ratio.
In addition, the researchers also discovered that the charge-to-mass ratios they measured do not vary by more than 720 parts per trillion per day, as Earth rotates on its axis and travels around the sun. This suggests that protons and antiprotons behave the same way over time as they zip through space at the same velocity, meaning they do not violate what is known as charge-parity-time, or CPT symmetry.
CPT symmetry is a key component of the Standard Model of particle physics, the best description to date of how the elementary particles making up the universe behave. No known violations of CPT symmetry exist. "Any detected CPT violation will have huge impact on our understanding of nature," Ulmer said.
Furthermore, these charge-to-mass ratios did not differ by more than 870 parts per billion in Earth's gravitational field. This means the weak equivalence principle, which holds that all matter falls at the same rate in the same gravitational field, also holds at this level of accuracy. The weak equivalence principle is a keystone of Einstein's theory of general relativity, which among other things is the best explanation so far of how gravity works. No known violations of the weak equivalence principle exist, and any detected violations of it could lead to a revolution in science's understanding of gravity and space-time, and how both relate to matter and energy.
The scientists detailed their latest findings online Aug. 13 in the journal Nature.

Nice article ..makes you wonder if the universe wasnt full of something already that interfered with the perfect balance and let normal matter as we know it prevail.
a few grams of the two meeting together is supposed to result in something like this like that explosion in Chinas major industrial port its supposed to be TNT and 1st blast 3megaton and the second 21 megatons. These explosions look strange..note how one seems to fizzle brighter then super bright..just like a minii nuke. Timing seems peculiar after the devaluation which is putting us up against the ropes..Nahh.we wouldnt do that

Syfy Prepping Alien Drama 'Gateway' From 'Battlestar Galactica' Alum
The potential series is based on the award-winning best-seller from Frederik Pohl.
Syfy is continuing to bring some of the most beloved science fiction properties to television.
The NBCUniversal-owned cable network announced Thursday at the Television Critics Association's summer press tour that it is developing Frederik Pohl's award-winning best-seller Gateway as a series.
Josh Pate (ABC's Blood and Oil, USA's Good vs. Evil) and Battlestar Galactica alum David Eick will adapt the source material. Eick will revise Pate's pilot script and serve as showrunner, with both attached to exec produce the Universal Cable Productions entry alongside the De Laurentiis Co.'s Martha De Laurentiis, former Entertainment One Television executive Michael Rosenberg and Lorenzo De Maio. eOne senior vp U.S. scripted development Gerard Bocaccio will oversee the project for the company.
Gateway, which won the prized Hugo and Nebula awards, takes place in a world in which humanity has discovered an asteroid teeming with the long abandoned spaceships of an advanced alien race — the Heechee — setting in motion a gold rush for alien artifacts and technology. The ships are preprogrammed, transporting their voyagers to distant worlds of riches — or certain death. Undaunted by the peril or the odds, prospector Robinette Broadhead gambles everything on a journey to Gateway. After one nightmare mission, he returns to extraordinary wealth and luxury, but is haunted by the loss of his crewmates, including the love of his life.
The Syfy deal comes more than a year after eOne and the De Laurentiis Co. (Hannibal) teamed to develop the late Pohl's beloved book. The companies both acquired rights to the 1977 title following a bidding war. Gateway, also known as the Heechee saga, previously was in the works as a film. The book saga also included 1980's Beyond the Blue Event Horizon, Heechee Rendezvous (1984), The Annals of the Heechee (1987) and The Boy Who Would Live Forever: A Novel of Gateway (2004).
"We’re delighted to develop this fascinating First Contact story with long-time partners UCP and Entertainment One. Gateway is thought-provoking and unsettling, raising profound questions about mankind’s possible relationship with alien life,” said Syfy original content exec vp Bill McGoldrick.
Gateway reunites Eick with Syfy following his run on Battlestar Galactica and spinoff Caprica.
For Syfy, Gateway comes as the cabler has put a renewed focus on science fiction fare with series including Childhood's End and The Expanse, both of which bow Dec. 14, as well as The Magicians, Hunters, 12 Monkeys and more. The cabler is also adapting classic novels Brave New World, Hyperion, 3001 and more.
