Astronomers discover mysterious black hole as massive as 12 billion suns

posted by Laura Domela

In a galaxy far, far away—12.8 billion light-years away to be more exact—is a newly-discovered supermassive black hole that weighs as much as 12 billion of our suns. The most surprising thing about the black hole, though, is not its size but its age.

Black holes grow as they age, gobbling up gas and stars that foolishly venture too close. Astronomers have found more massive black holes before, but this one is surprisingly young. Because it is so far away, we "see" the black hole as it was 12.8 billion light-years ago, or only about 875 million years after the Big Bang. Astronomers are puzzled how this black hole grew so huge in so short a time.

Working with colleagues from Deakin University and CSIRO (Commonwealth Scientific and Industrial Research Organisation), researchers from Australia's Monash University have created the world's first 3D-printed jet engine. While they were at it, they created the world'ssecond one, too. One of them is currently on display at the International Air Show in Avalon, Australia, while the other can be seen at the headquarters of French aerospace company Microturbo, in Toulouse.

Among the artifacts at the British Museum in London is this ancient Babylonian customer service complaint which was inscribed on a clay tablet sometime around 1750 BC. The complaint is regarding problems with two shipments of copper ore, as the museum notes in their description:

Clay tablet; letter from Nanni to Ea-nasir complaining that the wrong grade of copper ore has been delivered after a gulf voyage and about misdirection and delay of a further delivery; slightly damaged.

3D engineered bone marrow-like material produces functioning human platelets

Researchers at Tufts University School of Engineering and the University of Pavia (Italy) have developed a three-dimensional tissue made from porous silk, that’s capable of producing platelets for clinical use. The development is expected to have a significant impact on treatment of blood diseases.

Platelets are cell fragments containing no nucleus, produced by megakaryocytes found in bone marrow. They’re an essential component in the blood clotting process, but can also play a role in strokes and heart attacks, making an increased understanding of their production an important area of investigation. In the study, researchers aimed to create an artificial bioreactor that mimics the microenvironment present in bone marrow, facilitating the artificial formation of platelets.

Google’s AI wins Space Invaders, proves “human-level control”

posted by Laura Domela

A new study has been published this week which suggests that artificial intelligence can now learn "human-level control." The team of researchers come from Google's DeepMind, where they're using Space Invaders - the video game - to show how the search for truly human artificial intelligence isn't too far off. The machine learns to play the video game, learns to win at the video game, and dominates all humans at the game they've created to help us defend our planet against the alien hordes. 

It's like The Last Starfighter - only this time, Google has created a computer that can defeat the invaders. Researchers at DeepMind suggest that Reinforcement Learning is one key to optimizing artificial intelligence.

Meet Grasp, a wearable that helps instructors micromanage you

posted by Larra Morris

Can you imagine having an instructor who peers over your shoulder all the time while you practice, say, cooking or coding? Awkwaaard. But if that's the only way you can force yourself to learn something, then this device called Grasp was made for you. It was designed to perch on your shoulder like a parrot, so an instructor can monitor and guide your every move from anywhere in the world. It has a mic, a camera and a laser pointer, all powered by an Arduino Yún board, to make real-time remote teaching more hands-on.
