Is A Coincidence Ever JUST A Coincidence? The New Science Of Synchronicity

One thing we’re always doing as a species is expanding our knowledge of the heavens. We send out probes, robots, satellites, spacecraft, all to map out and add to our ever-expanding picture of what the Universe looks like.

But what if that picture suddenly became smaller? That is exactly what happened when new data from the Planck satellite tightened our previous notions of the observable universe, shrinking its area by 0.7%.

If you’ve never realized, we don’t actually see all of the stars in the Universe. If we did, night time sky would be a whole lot brighter. Instead, we see everything within a particular radius, the particle horizon. Any particle of light emitted outside that particle horizon is too far to have reached us.

So if we want to know just how large the observable universe is, we just have to figure out the distance between us and that particle horizon, right?

As it turns out, not quite.

The universe, specifically spacetime, is continuously expanding, with points in the universe moving further apart. This not only changes the distance between objects but also how fast light is moving in the universe. 

The movement of spacetime has an effect on which photons reach us and can be observed.

So how do you calculate the radius? Back in 2003, scientists came up with an equation that took an event called “the recombination” as a reference point in the universe’s history. They combined that with the rate of the expansion of the universe and several other factors, in the end coming up with a number.

Back in 2003, that number was a radius of 45.66 billion light-years. Now, new data revealed a far more accurate number: 45.34 billion light-years.

“A difference of 320 million light-years might be peanuts on the cosmic scale, but it does make our knowable universe a little bit cozier,” Nick Tomasello from the University of the Sciences in Philadelphia writes over at Medium.

The study has been accepted for publication in an upcoming edition of Advances in Astrophysics.

Brain, Bone and Blood Vessels Coming Hot Off the Press

Could the days of custom clavicles and bespoke bladders produced just in the knick of time for suffering patients be around the corner?

While keeping an eye on tissue engineering studies, we’ve been seeing some significant wins in the lab that are bringing the sci-fi future of on-demand 3-D printed organs, bone and blood vessels closer. 

Harvard and Brown bioengineers are taking their own routes to build complex tissues in customized 3-D printers. And just the other week, we reported on newly unveiled work at the University of Florida to print complex soft structures in baths that could one day birth replacement human parts along with soft robots.

Now, Carnegie Mellon engineers reported on Friday that they had successfully printed simplified proof-of-concept anatomical structures like mini femurs, blood vessels and brains suspended in soft gelatin. Learn more and see a video below.

Artificial Intelligence Program Passes Entrance Exam, Can Be Accepted Into University

The National Institute of Informatics has developed an Artificial Intelligence (AI) program that was able to achieve an above-average score on a college entrance exam for the first time ever. The test covered five subjects including Math, Physics, and English.

Ultimately, the Institute is attempting to develop an AI that could perform well enough on Japan’s standardized college entrance exam to be accepted into the University of Tokyo, Japan’s highest-ranked university. And they hope to complete their task by 2021.

To date, the AI received a top score of 511 points out of 950, which is above the national average of 416 points.

According to the institute, the AI has at least an 80% chance of being accepted to 441 private universities and 33 national universities with that score, odds that would make any aspiring student quite happy.

Using copper to prevent the spread of respiratory viruses

New research from the University of Southampton has found that copper can effectively help to prevent the spread of respiratory viruses, which are linked to severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

The Force Awakens: China Readies for Space Warfare

Moscow (Sputnik) Jan 01, 2016 The Chinese military is undergoing a gradual shift to cyber and space warfare, and the move is more visible now as a new command structure has been created. After testing an anti-satellite weapon last fall, China moved one step forward in its preparations for future warfare, with the emergence of a brand-new Space Force, as reported by Washington Times. In the event of an armed confl Full article

A lot of people live in fear because they haven’t figured out how you’re going to react when faced with a certain set of circumstances. I’ve come to terms with this by looking deeply into whatever makes me fearful - what are the key elements that get the hairs up on the back of my neck - and then figuring out what I can do about it.
