Liquid metal nano printing set to revolutionize electronics

February 17, 2017

A new technique using liquid metals to create integrated circuits that are just atoms thick could lead to the next big advance for electronics.

The process opens the way for the production of large wafers around 1.5 nanometres in depth (a sheet of paper, by comparison, is 100,000nm thick).

Other techniques have proven unreliable in terms of quality, difficult to scale up and function only at very high temperatures — 550 degrees or more.

Scientists create a 3-D bioprinter to print human skin

January 24, 2017

In research that has recently been published in the electronic version of the scientific journal Biofabrication, a team of researchers has demonstrated, for the first time, that, using the new 3D printing technology, it is possible to produce proper human skin. One of the authors, Josa Luis Jorcano, professor in UC3M’s department of Bioengineering and Aerospace Engineering and head of the Mixed Unit CIEMAT/UC3M in Biomedical Engineering, points out that this skin “can be transplanted to patients or used in business settings to test chemical products, cosmetics or pharmaceutical products in quantities and with timetables and prices that are compatible with these uses.”

Coming Soon: Turn the flat-screen TV in your living room into a wireless charging station

January 4, 2017

The flat-screen TV on your living room wall could soon be remotely charging any device within its line of sight. Well, not your actual TV, but a device that is similar in size and shape.

In a paper posted October 23, 2016 on the arXiv pre-print repository, engineers at Duke University, the University of Washington and Intellectual Ventures’ Invention Science Fund (ISF) show that the technology already exists to build such a system –it’s only a matter of taking the time to design it.

Chemistry research breakthrough that could improve nuclear waste recycling technologies

December 21, 2016

Researchers from The University of Manchester have taken a major step forward by describing the quantitative modelling of the electronic structure of a family of uranium nitride compounds – a process that could in the future help with nuclear waste recycling technologies.

This research has been published in the leading multi-disciplinary journal Nature Communications.

Learn how it takes just 6 seconds to hack a credit card

December 2, 2016

  • New research reveals the ease with which criminals can hack an account without ANY of the card details
  • Dubbed the Distributed Guessing Attack, the team from Newcastle University, UK, say it can take just six seconds to find the card number, the expiry date and the CVV using nothing more than a laptop and an internet connection
  • Circumventing all the security features put in place to protect online payments from fraud, investigators on the recent Tesco cyberattack believe that hackers used a ‘guessing attack’ method to defraud Tesco customers of £2.5m

Working out the card number, expiry date and security code of any Visa credit or debit card can take as little as six seconds and uses nothing more than guesswork, new research has shown.

New software continuously scrambles code to foil cyber attacks

November 17, 2016

As long as humans are writing software, there will be coding mistakes for malicious hackers to exploit. A single bug can open the door to attackers deleting files, copying credit card numbers or carrying out political mischief.

A new program called Shuffler tries to preempt such attacks by allowing programs to continuously scramble their code as they run, effectively closing the window of opportunity for an attack. The technique is described in a study presented this month at the USENIX Symposium on Operating Systems and Design (OSDI) in Savannah, Ga. Read more

Simulation brings global 100 percent renewable electricity system to life for the first time

November 9, 2016

A new model developed by Lappeenranta University of Technology (LUT) shows how an electricity system mainly based on solar and wind works in all regions of the world. It shows the functioning of an electricity system that fulfils the targets set by the Paris agreement by using only renewable energy sources.

The global Internet of Energy Model visualizes a 100 percent renewable energy system (100%RE) for the electricity sector for 2030. It can do this for the entire world which, in the model, has been structured into 145 regions, which are all visualised, and aggregated to 9 major world regions. Read more

Hybrid 3-D Virtual Reality Environment Comes to the Cinema

November 4, 2016

Paris’s first virtual reality (VR) theatre opened its doors. It promises viewers an unparalleled experience using VR headsets and headphones that propel them into a virtual world for 40-minute shows. Yet the designer Tomás Dorta, a professor at the University of Montreal, does not believe in it. “Viewers wearing individual headsets are isolated from others, which is contrary to the collective experience we are looking for when we go to the movies,” he explained.

MIT study reveals new technique for machine-learning systems’ decisions

October 31, 2016

In recent years, the best-performing systems in artificial-intelligence research have come courtesy of neural networks, which look for patterns in training data that yield useful predictions or classifications. A neural net might, for instance, be trained to recognize certain objects in digital images or to infer the topics of texts.

But neural nets are black boxes. After training, a network may be very good at classifying data, but even its creators will have no idea why. With visual data, it’s sometimes possible to automate experiments that determine which visual features a neural net is responding to. But text-processing systems tend to be more opaque. Read more
