But the alleged signal is what got the attention of Maccone and his Russian colleagues. Shostak characterized it as 2.7 cm in wavelength and 11 GHz in frequency, which makes it an ultra high-frequency signal that’s not too different from a digital TV signal. Assuming the signal is real, Shostak says it’d have to be incredibly powerful for Earth to have detected it coming from HD 164595. “If they’re aiming it straight at Earth, it’d require about 50 trillion watts,” Shostak said, or 50 followed by 12 zeros. “That’s a little more than all of humanity uses at any moment, more than all the energy being used by all of our power plants, cars, buses, planes, trains, and so on.” And if the signal is being broadcast in all directions? no dataThe power requirement gets even steeper, he said. “The amount of power you’d need is something like 100 billion billion watts,” Shostak says, or 100 followed by 20 zeroes. That’s roughly 100 million times more energy required compared to a focused, beam-type signal pointed at Earth. Either amount is “pretty impressive,” Shostak said, and unlikely to be alien in origin. ‘Probably not E.T.’ ratan 600 radio telescope russia More Read More (The RATAN-600 radio telescope in Russia.

Highest death risk comes weeks after low level trauma: Study By Stephen Feller | Aug. 29, 2016 at 3:30 PM Comments BOSTON, Aug. 29 (UPI) — After 50 years of trying, researchers may have found an effective way to use contact lenses to deliver drugs for conditions treated with eye drops. Glaucoma patients may soon be able to treat the condition using a lens that slowly releases medication to the eye, with some tests with monkeys suggesting the treatment method could be more effective than the standard eye drops, researchers at Harvard Medical School report in a new study. The leading cause of irreversible blindness, glaucoma has no cure but doctors attempt to slow its development by prescribing drops for patients. The drops, however, often cause stinging and burning, and may be difficult for some patients to use, if they try to use them at all. “If we can address the problem of compliance, we may help patients adhere to the therapy necessary to maintain vision in diseases like glaucoma, saving millions from preventable blindness,” Dr. Joseph Ciolino, an ophthalmologist at Massachusetts Eye and Ear and an assistant professor at Harvard, said in a press release . “This study also raises the possibility that we may have an option for glaucoma that’s more effective than what we have today.” Using a novel design, researchers created a contact lens with a thin film of drug-encapsulated polymers around its edges. The polymer film slows release of the drug — previous attempts at a drug-eluting lens released medications far too fast — while remaining on the side of the lens so its center remains clear for vision.
