A landmark day for Einstein and our understanding of the universe: the detection of gravitational waves. World Science Festival’s own Brian Greene explains the discovery.
More advancement in Quantum Computing — researchers in Finland have found a way to keep the processor chip cooled without causing disrupting computer operations which has been a big challenge for Quantum Chips.
AALTO, Finland, Feb. 11, 2016 — A thermal-transport method that uses photons as carriers has been demonstrated over 1-m distances. The fundamental advance in heat conduction could drive the development of quantum computers.

The late Supreme Court Justice Potter Stewart once said, “Ethics is knowing the difference between what you have a right to do and what is right to do.”
As artificial intelligence (AI) systems become more and more advanced, can the same statement apply to computers?
According to many technology moguls and policymakers, the answer is this: We’re not quite there yet.
“That in general is good advice for people creating companies,” Musk said to students. “Start with the minimally useful system.”

Scientists Have Confirmed the Existence of Gravitational Waves.
We just found gravitational waves!! Scientists at LIGO have confirmed!
“The finding: There’s little correlation between a group’s collective intelligence and the IQs of its individual members. But if a group includes more women, its collective intelligence rises.”
Interesting. What do you think of this?
A mammal brain has been defrosted from cryogenic storage in an almost perfect state for the first time. This breakthrough, accomplished using a rabbit brain, brings us one – albeit tiny – step closer to the prospect of reanimating a human brain that has been cryogenically preserved.
After death, organs begin to decay, but we can delay this by cooling these tissues, just like freezing food. But in the same way that a frozen strawberry becomes soggy when defrosted, it is difficult to perfectly preserve mammals at cold temperatures. We, and strawberries, contain large amounts of water, which freezes into ice crystals that damage cells.
Cryoprotectants can prevent this ice damage, working like medical-grade antifreezes and preventing organs from freezing. This works in small worms and rabbit kidneys, but it needs to be administered quickly, which usually causes brains to dehydrate and shrink.
A team of researchers has achieved the fastest ever transmission rate for digital information between a single transmitter and receiver, sending data optically at a frankly ridiculous 1.125 terabits per second.
The result, achieved by scientists at University College London, uses a series of signal processing techniques to achieve the speed. But first, the lead researcher, Dr Robert Maher, puts the rate into context in a press release:
For comparison this is almost 50,000 times greater than the average speed of a UK broadband connection of 24 megabits per second… To give an example, the data rate we have achieved would allow the entire HD Game of Thrones series to be downloaded within one second.
