Scientists develop world’s first light-seeking synthetic nanorobot

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.

Engineering Fusion Energy By 2025

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’.

Magnetic material lets ice slide right off

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.

D-Wave Names Jeremy Hilton as Senior Vice President, Systems, Founder Geordie Rose Now Special Advisor

Congrats geordie rose and jeremy hilton ; d-wave ROCKS!

News posting on T-Net)

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.

Hilton, who was previously the vice president of processor development, joined D-Wave in 2000, and has been instrumental in developing the world’s first scalable quantum processors. Hilton also led the development of D-Wave’s superconducting integrated circuit foundry. He is a named inventor on 34 granted U.S. patents.

“Jeremy has almost two decades of experience developing the most advanced scalable quantum computing systems in the world. We’re lucky to have him on the team,” said CEO Vern Brownell.

Why “Computronium” is really “Unobtanium”

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!

Yale Engineers Advance Quantum Technology With Photon Control

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.

A Tiny Machine: UCSB electrical and computer engineers design an infinitesimal computing device

Abstract: In 1959 renowned physicist Richard Feynman, in his talk “Plenty of Room at the Bottom,” spoke of a future in which tiny machines could perform huge feats. Like many forward-looking concepts, his molecule and atom-sized world remained for years in the realm of science fiction.

And then, scientists and other creative thinkers began to realize Feynman’s nanotechnological visions.

In the spirit of Feynman’s insight, and in response to the challenges he issued as a way to inspire scientific and engineering creativity, electrical and computer engineers at UC Santa Barbara have developed a design for a functional nanoscale computing device. The concept involves a dense, three-dimensional circuit operating on an unconventional type of logic that could, theoretically, be packed into a block no bigger than 50 nanometers on any side.

Mars Medical Challenge Asks Students to Design 3D Printable Items to Keep Astronauts Healthy on Mars

The team of NASA, the American Society of Mechanical Engineering (ASME), and online educational platform Future Engineers has been a lot of fun to follow over the last year. Their collaborative 3D Printing in Space Challenges have resulted in some amazing, ingenious inventions from children as young as five years old, all aimed at improving the daily lives of astronauts now and in the future, on the International Space Station and, one day, on Mars.

The winners of the last challenge, the Think Outside the Box Challenge, were announced a few weeks ago, and now the three organizations have announced the fifth challenge in the series. This time, it’s geared directly towards a future Mars mission. The Mars Medical Challenge asks participants to create a digital 3D model of a medical or dental item that an astronaut could use on a three-year mission to Mars.
