This is a nice vid but there are two things to note.
1. he does not mention Callisto in place of Europa. Europa gets enough radiation to kill you in a day where on Callisto you would not even get the radiation you get here on Earth.

I said over a year ago that if the US will not do it China will. Whilst there was talk about a moratorium on CRISPR in the US the Chinese were forging ahead and taking steps to become a world leader in biotech. Well here we are, they have deployed CRISPR in humans for cancer and this is only the start. As George Church advocates, we should have appropriate engineering safety measures in place but we should push ahead and do these things.
The move by Chinese scientists could spark a biomedical duel between China and the United States.
With bots the size of a single blood cell, this could spur a huge leap in the field of non-invasive surgeries.
Scientists have developed the world’s first light-seeking synthetic nanorobot which may help surgeons remove tumours and enable more precise engineering of targeted medications.
It has been a dream in science fiction for decades that tiny robots can fundamentally change our daily life. The famous science fiction movie “Fantastic Voyage” is a very good example, with a group of scientists driving their miniaturised Nano-submarine inside human body to repair a damaged brain.

Tokamak Energy.
The world needs abundant, clean energy. Nuclear fusion — with no CO2 emissions, no risk of meltdown and no long-lived radioactive waste — is the obvious solution, but it is very hard to achieve.
The challenge is that fusion only happens in stars, where the huge gravitational force creates pressures and temperatures so intense that usually repulsive particles will collide and fuse; hence “fusion”. On Earth we need to create similar conditions, holding a hot, electrically-charged plasma at high enough pressure for long enough for fusion reactions to occur. The scientific and engineering challenges behind putting a star in a box are large, to say the least. Without proper confinement of the plasma, the reaction would stop. The plasma must be isolated from the walls of the reactor — a feat that can be performed most effectively by magnets. The most advanced machine for this purpose is the ‘tokamak’.
For most people, icy conditions mean a slippery pavement or trying to chip the car out of a freezing glaze, but icing can also bring down aircraft, snap power lines, and cause a surprising amount of structural damage. Now scientists at the University of Houston (UH) have come up with a surprising solution – and it involves magnets.
The problem with icing is that when droplets of freezing or supercooled water strike a surface, they wet or adhere to it, so more and more droplets can join the party. To de-ice a surface, you need to either melt the ice, break it off, dissolve it, or alter the surface so the ice can’t stick to it in the first place.
According to Hadi Ghasemi from the UH Department of Mechanical Engineering, “icephobic” surfaces that are non-wetting or liquid infused have shown promise in the past, but suffer from high freezing temperatures, high ice adhesion strength, and high cost.
Researchers have developed the world’s first light-seeking synthetic nanorobot that can help surgeons remove tumors and enable more precise engineering of targeted medications.

With size comparable to a blood cell, these tiny robots have the potential to be injected into a patient’s body, the study said.

Burnaby, BC, November 4, 2016—(T-Net)—D-Wave Systems Inc., the world’s first quantum computing company, announced the promotion of Jeremy Hilton to senior vice president, systems, with responsibility for driving the company’s quantum processor and systems research and engineering functions.
Computronium is defined by some as a substance which approaches the theoretical limit of computational power that we can achieve through engineering of the matter around us. It would mean that every atom of a piece of matter would be put to useful work doing computation. Such a system would reside at the ultimate limits of efficiency, and the smallest amount of energy possible would be wasted through the generation of heat. Computronium crops up in science fiction a lot, usually as something that advanced civilizations have created, occasionally causing conflicts due to intensive harvesting of matter from their galaxy to further their processing power. The idea is also also linked with advanced machine intelligence: A block of matter which does nothing other than compute could presumably would be incredibly sought after by any artificial intelligence looking to get the most compact and powerful brain for its money!
Engineers from Yale University have developed a new technique to control the frequency of single photons.
The ability to control the frequency of single photons is crucial to realize the potential of quantum communications and quantum computing. The current methods for changing photon frequency, however, bring with them significant drawbacks.
Researchers in the lab of Hong Tang, the Llewellyn West Jones, Jr. Professor of Electrical Engineering & Physics, have developed a technique that avoids these obstacles. The results of their work are published today in Nature Photonics. Linran Fan, a Ph.D. student in Tang’s lab, is the lead author.
