+ - Virtual Telescope Readies to Image Black Hole's 'Ring of Fire'->

Submitted by astroengine
astroengine writes: With the addition of a telescope at the southern-most point of Earth, the Event Horizon Telescope (EHT) now spans the diameter of our planet and, when the vast project goes online, astronomers will get their first glimpse of the bright ring surrounding a supermassive black hole. Using a method known as Very Long Baseline Interferometry, or VLBI, astronomers can combine the observing power of many telescopes situated at distant locations around the planet. The distance between those observatories, known as the “baseline,” then mimics a virtual telescope of that diameter. Now, in an attempt to make direct observations of the supermassive black hole in the center of our galaxy, located at a powerful radio emission source called Sagittarius A*, the South Pole Telescope (SPT) at the National Science Foundation’s Amundsen-Scott South Pole Station has been linked to the EHT and the stage is set for a historic new era of exploring the most extreme objects in the known universe. “Now that we’ve done VLBI with the SPT, the Event Horizon Telescope really does span the whole Earth, from the Submillimeter Telescope on Mount Graham in Arizona, to California, Hawaii, Chile, Mexico, Spain and the South Pole,” said Dan Marrone of the University of Arizona. “The baselines to SPT give us two to three times more resolution than our past arrays, which is absolutely crucial to the goals of the EHT. To verify the existence of an event horizon, the ‘edge’ of a black hole, and more generally to test Einstein’s theory of general relativity, we need a very detailed picture of a black hole. With the full EHT, we should be able to do this.”

+ - iOS WiFi Bug Allows Remote Reboot Of All Devices In Area 2

Submitted by BronsCon
BronsCon writes: A recently disclosed flaw in iOS 8 dubbed "No iOS Zone" allows an attacker to create a WiFi hot spot that will cause iOS devices to become unstable, crash, and reboot, even when in offline mode. Adi Sharabani and Yair Amit of Skycure are working with Apple for a fix; but, for now, the only workaround is to simply not be in range of such a malicious network.

Morally speaking, testing on lawyers and politicians would be preferable to using rats. However, scientific consensus is that the lack of a high-functioning nervous system in most politicians and lobbyists, et al, means that any results would not likely work on real humans.

Probably not. Any hacker with two brain cells to rub together would quietly infiltrate systems in company A, from there infiltrate Company B, C & D, rinse/repeat until sufficient layers of abstraction sit between them & their target, and then use them to attack the real target. If the response of victim X is to nuke the IPs from which the attack came, they are a) hitting the wrong entity, b) potentially destroying evidence left by the real perps, and c) probably initiating a re-retaliation from the victim of their attack.

The theory behind the Bill of Rights says that our rights exist whether or not the Bill of Rights says we do, or because it is convenient, or because it is logical to your mind. We have them because they are part of our nature as human beings, and the rights in the Bill of Rights confirm that there are certain aspects of our nature as people in which the government has no authority to intervene.

The ability to freely think, speak, associate with others, and move about, or the ability to worship as we please, or not worship at all, involve our sovereignty over our own minds and persons. The government cannot compel moon-landing doubters and conspiracy theorists to disavow their crackpot ideas. Not because the crackpots are necessarily right (sometimes paranoid bastards ARE right, after all), but because our government has no sovereign right to rule our minds. An earlier commenter related the 5th amendment protections as analogous to the 4th interms of search and seizure. I view the 5th amendment's right to not self-incriminate as more like an intersection of the 1st and 4th amendments, because it involves not just our things, but our thoughts. I see it as self-evident that our thoughts are more closely bound to our being, and more deserving of impenetrable legal protection than our effects.

At their root, "Rights" as the Constitution lays them out are an explicit restriction on governmental power. Not the other way around.

+ - College student creates gel to stop bleeding, star healing->

Submitted by NotBornYesterday
NotBornYesterday writes: A 20-year-old New York University student has invented a gel which, according to him, can stop heavy bleeding instantly. With the introduction of the latest invention by Joe Landolina,routine bandages could soon become a thing of the past. According to Landolina the Veti-Gel produced by him, can not only stop bleeding but also instantly start the healing process even on major wounds and wounds on internal organs and key arteries.

The gel, according to the report, is an artificial version of extracellular matrix, which is a substance present in the connective tissue which holds up an animal body together.

In a video with the article, the experimenter can be seen cutting a deep slice into the pork flesh while real pigs blood is being injected into the flesh at the same time. Soon after the flesh is cut, the blood starts flowing freely. However, as soon as the gel is applied on the cut and second liquid sprayed over it, the bleeding suddenly stops.

I mean, a guy arrested at the scene of a mass shooting, covered in blood and holding an assault rifle, screaming about how the aliens in his head told him to murder all of mankind... still gets a trial. Timothy McVeigh (the second biggest terrorist to attack US soil) got a trial. People who systematically abduct and rape hundreds of little girls and hide their bodies in barrels get a trial.

I'm certain the US would have loved to put him on trial. If he had wanted one, all he had to do was surrender. The loonies you mention, both hypothetical and real, seem to have been willing to be taken alive. Whether he really believed in his 72 virgins or not, he obviously preferred death to arrest.

Factorials were someone's attempt to make math LOOK exciting.
