Just when they thought they had something...but...no alien signal...
The team of scientists manning a huge radio telescope high in the Caucasus region have said that the signal they believed at first to have originated from distant star HD164595 was most likely the result of ?terrestrial interference?.
The Ratan-600, a telescope located in Zelenchukskaya in the Caucasus mountains straddling Europe and Asia, surveys as much of the sky as possible for signals of possible interest. Last year, the team told a group of fellow astronomers in Moscow it believed the telescope intercepted a ?candidate signal? worthy of further monitoring.
Unfortunately, though the information took a year to reach the Search for Extraterrestrial Intelligence (Seti) community in the rest of the world, the astronomers from Moscow State University and the Russian Academy of Sciences (RAS), further scrutiny turned out to be necessary: ?Subsequent processing and analysis of the signal revealed its most probable terrestrial origin,? wrote Yulia Sotnikova of the RAS.

Cyborg calling! Memory Prosthetic Implantation:
...what in god's good earth is a memory prosthetic?...this is a first of its kind device, potentially as revolutionary as the Xerox machine. And the comparison goes one step further, because like a Xerox machine, the purpose of the memory prosthetic is to create a facsimile of the impressions fed into it, albeit one stored in long term memory rather than on paper. How it goes about this complicated task is where the story gets interesting.
A basic understanding of how the brain goes about storing information in long term memory will prove helpful at this point. While certain details of this process remain sketchy even unto neuroscientists, the basic working of this has been discovered to the degree that we can now intervene at important junctures with a purpose of aiding or inhibiting the final outcome. In this case, the brain component involved in the conversion of short term declarative memories such as names and faces, into long term memories, is the hippocampus. When the hippocampus is injured, or in some other way degraded, the neuronal signals it receives from the short term memory fail to get converted into long term memories.
Enter the brain prosthetic. Using a computer generated model, Ted Berger and the fellow researchers at UCLA who went on to launch Kernel, were able to map patterns of neuronal firing that the hippocampus uses to convert short term memories into long term ones. Having worked out the equations that could approximate the output given by the hippocampus, it was only a small leap to load these models onto a computer chip which could be embedded in the human brain and take the place of an injured or missing hippocampus. This is off course a gross exaggeration, since anytime an artificial, electronic device is squeezed into the delicate tissue of the human brain, numerous complications arise. However, these have all been sorted out to the degree that the FDA has cleared the device for clinical trials in humans - a not insignificant accomplishment in itself given the rigorous and stringent guidelines involved in human trials.

"Negative Differential Resistance" or NDR. What it is and how a group of Canadian physicists & scientists finally solved the puzzle:
A team of University of Alberta physicists has deciphered a scientific mystery that evaded computer whizzes for decades, resulting in a discovery potentially worth billions of dollars to the technology industry.
His study sought to control a seemingly uncontrollable electrical phenomenon known as negative differential resistance (NDR).
?The simplest way to think about it is ? electricity behaving backwards,? Wolkow said, likening the process to water being pushed through a hose whereby increasing the pressure forces the water to move faster. Electricity acts in a similar way, he said, but instead of pressure, it?s voltage that increases the flow of the current.
?The really weird thing is in some rare cases ? you push harder, and the current goes slower instead of faster.?
Wolkow?s team was able to determine the exact atomic structure that creates NDR. He said the potential monetary value of a hybrid transistor or NDR circuit has been well-established for decades, but no one understood how to control the effect.
The discovery could lead to building smaller, cheaper and faster computers...

Albert Einstein's Theory of Relativity came to light when two neutron stars collided emitting gravitational waves as detected by ALIGO -- Advanced Laser Interferometer Gravitational Observatory -- located in the US & Italy.
Data culled from more than 70 observatories worldwide, and the involvement of over 3000 researchers, yielded the missing link to Einstein's prediction answered a century later. While the ALIGOs were able to detect the gravitational waves and black holes up to now, the lack of observing the collision of the two neutron stars left the question unanswered -- basically the how part. The latter came to fruition leaving space observers in a state of awe and elation:
Simply put, a cataclysmic event in the world of astrophysics. Albert Einstein would be proud.

Brilliant scientist Stephen Hawking, who was British, was afflicted with ALS (Amyotrophic Lateral Sclerosis) or also known as Lou Gehrig disease, a neuromuscular disorder, defied the medical odds and outlived the disease until his death today at 76.
Considered by many to be the world's greatest living scientist, Hawking was also a cosmologist, astronomer, mathematician and author of numerous books including the landmark "A Brief History of Time," which has sold more than 10 million copies.
With fellow physicist Roger Penrose, Hawking merged Einstein's theory of relativity with quantum theory to suggest that space and time would begin with the Big Bang and end in black holes. Hawking also discovered that black holes were not completely black but emit radiation and would likely eventually evaporate and disappear.

Black hole captured by planet-wide telescopes. It is considered by many to be the gateway to another dimension. In accordance with Einstein?s Theory of Relativity of space, time, and energy, a Black hole is where nothing can escape or return from it.
One of the greatest mysteries of the universe, now uncovered but still so little understood. Thanks to MIT physicist Katie Bouman, whose algorithm helped piece the data of the EHT ? Event Horizon Telescope ? the eight telescopes that were placed all around the planet.
An achievement more than ten years in the making.
Quite the discovery.
