Dr. Aubrey de Grey is a biomedical gerontologist based Mountain View, California, USA, and is the Chief Science Officer of SENS Research Foundation, a California-based 501©(3) biomedical research charity that performs and funds laboratory research dedicated to combating the aging process. He is also Editor-in-Chief of Rejuvenation Research, the world’s highest-impact peer-reviewed journal focused on intervention in aging. He received his BA in computer science and Ph.D. in biology from the University of Cambridge. His research interests encompass the characterisation of all the accumulating and eventually pathogenic molecular and cellular side-effects of metabolism (“damage”) that constitute mammalian aging and the design of interventions to repair and/or obviate that damage.

Hmmmm.

Computers based on quantum mechanics have been in the realm of science fiction for years, but recently companies like Google (Nasdaq: GOOGL), and even the National Security Agency, have started to think practically about what their existence would mean.

These super-powerful computers would be exciting in many respects, but they would also be able to break the methods of data encryption that currently make it safe to browse the internet or pay for things online.

A blueprint for QC larger servers mass production. The question is; is it the right blueprint for everyone? Not sure.

An international team, led by a scientist from the University of Sussex, have today unveiled the first practical blueprint for how to build a quantum computer, the most powerful computer on Earth.

This huge leap forward towards creating a universal quantum computer is published today (1 February 2017) in the influential journal Science Advances. It has long been known that such a computer would revolutionise industry, science and commerce on a similar scale as the invention of ordinary computers. But this new work features the actual industrial blueprint to construct such a large-scale machine, more powerful in solving certain problems than any computer ever constructed before.

Once built, the computer’s capabilities mean it would have the potential to answer many questions in science; create new, lifesaving medicines; solve the most mind-boggling scientific problems; unravel the yet unknown mysteries of the furthest reaches of deepest space; and solve some problems that an ordinary computer would take billions of years to compute.

More detailed write up on QC Blueprint introduced this week. It does seem to try to address scalability; however, the real test is when we test a smart device and a small server with the blueprint.

The availability of a universal quantum computer may have a fundamental impact on a vast number of research fields and on society as a whole. An increasingly large scientific and industrial community is working toward the realization of such a device. An arbitrarily large quantum computer may best be constructed using a modular approach. We present a blueprint for a trapped ion–based scalable quantum computer module, making it possible to create a scalable quantum computer architecture based on long-wavelength radiation quantum gates. The modules control all operations as stand-alone units, are constructed using silicon microfabrication techniques, and are within reach of current technology. To perform the required quantum computations, the modules make use of long-wavelength radiation–based quantum gate technology. To scale this microwave quantum computer architecture to a large size, we present a fully scalable design that makes use of ion transport between different modules, thereby allowing arbitrarily many modules to be connected to construct a large-scale device. A high error–threshold surface error correction code can be implemented in the proposed architecture to execute fault-tolerant operations. With appropriate adjustments, the proposed modules are also suitable for alternative trapped ion quantum computer architectures, such as schemes using photonic interconnects.

Watch out for the black holes in those QC chips.

Eindhoven professor Rembert Duine has proposed a way to simulate black holes on an electronic chip. This makes it possible to study fundamental aspects of black holes in a laboratory on earth. Additionally, the underlying research may be useful for quantum technologies. Duine (also working at Utrecht University) and colleagues from Chile published their results today in Physical Review Letters.

“Right now, it’s purely theoretical,” says Duine, “but all the ingredients already exist. This could be happening in a lab one or two years from now.” One possibility is in the group of Physics of Nanostructures in the Department of Applied Physics. According to Duine, in these labs experiments are being done that are necessary to create this type of black holes.

Event horizon

Black holes in space are so dense that nothing can escape their gravitational pull once it passes a point of no return called the event horizon. The researchers have now found a way to make such points of no return for spin waves, fluctuations that propagate in magnetic materials. When an electric current runs through the material, the electrons drag these waves along.

In Brief

  • Czech scientists have developed a 3D printed model of a functioning lung that can simulate real-life conditions like asthma and other chronic breathing problems.
  • Their model could lead to new treatment options for those suffering from chronic obstructive pulmonary diseases, which claim more than 3 million lives every year.

3D printing is opening so many new doors in the medical field. The technology allows researchers and doctors to manipulate the finest design nuances of models as well as the properties of the materials used to build them. These 3D printed models of organs, bones, and other organic subjects are valuable tools for both students learning the basics and medical experts testing new treatments and conducting experimental research.

Now, Czech scientists from the Brno University of Technology have developed a 3D printed model of a functioning lung that can simulate real-life conditions like asthma and other chronic breathing problems. They believe that their 3D printed mechanical model and its computer-based counterpart can be used to devise new, more precise treatment methods. It would be particularly useful in creating a reference standard for inhaled drugs. “This model will show whether an inhaled drug will settle in the concrete areas where we need it to,” Miroslav Jicha, the head of the research team, told Reuters.

What do the Oral-B CrossAction toothbrush, about a thousand musical compositions and even a few recent food recipes all have in common?

They were invented by computers, but you won’t find a nonhuman credited with any of these creations on U.S. patents. One patent attorney would like to see that changed.

Ryan Abbott is petitioning to address what he sees as more than a quirk in current laws but a fundamental flaw in policy that could have wide-ranging implications in areas of patent jurisprudence, economics and beyond if his proposals are adopted.

Most of us probably don’t think too much about the foodstuffs we buy in the supermarket. But behind the scenes, today’s food production system relies on a centralized, industrial-scale supply chain that’s still dependent upon soil-based agriculture for the majority of our food crops.

In many instances, that means that food has to travel long distances from farm to table, meaning that food has lost much of its freshness and nutritional value by the time it reaches your table. There’s also a growing awareness that this model isn’t sustainable: the pressures of increasing urbanization and loss of arable land, rising populations and the increased frequency of extreme weather events like droughts and floods — brought on by climate change — means that slowly but surely, we are going to have to change the way we grow our food.

There are some indications of this shift: the appearance of urban rooftop farms, an explosion of interest in automated hydroponic systems. The problem with all these systems is that their platforms are proprietary, and the lack of a common platform between them means these won’t necessarily scale up.
