Artificial intelligence seems to be making enormous advances. It has become the key technology behind self-driving cars, automatic translation systems, speech and textual analysis, image processing and all kinds of diagnosis and recognition systems. In many cases, AI can surpass the best human performance levels at specific tasks. We are witnessing the emergence of a new commercial industry with intense activity, massive financial investment, and tremendous potential. It would seem that there are no areas that are beyond improvement by AI – no tasks that cannot be automated, no problems that can’t at least be helped by an AI application. But is this strictly true? Theoretical studies…

The big idea For the first time, my colleagues and I have built a single electronic device that is capable of copying the functions of neuron cells in a brain. We then connected 20 of them together to perform a complicated calculation. This work shows that it is scientifically possible to make an advanced computer that does not rely on transistors to calculate and that uses much less electrical power than today’s data centers. Our research, which I began in 2004, was motivated by two questions. Can we build a single electronic element – the equivalent of a transistor or switch – that performs…

This year has brought many changes into our everyday routine. The COVID-19 pandemic has forced us to physically distance ourselves as much as possible, while masks and other public health measures remain in place in the outside world. The number of COVID-19 cases are rising in Canada and remain high in the United States. Schools have reopened, with much debate as to whether or not they should to reduce the risk of transmission. As the days get shorter and the weather gets colder, and we anticipate the arrival of a second wave, we’ll all be looking for activities to stay inside. Gaming activities As…

Facebook Messenger and Instagram’s direct messaging services will be integrated into one system, Facebook has announced. The merge will allow shared messaging across both platforms, as well as video calls and the use of a range of tools drawn from both platforms. It’s currently being rolled out across countries on an opt-in basis, but hasn’t yet reached some locations. Facebook CEO Mark Zuckerberg announced plans in March last year to integrate Messenger, Instagram Direct and WhatsApp into a unified messaging experience. At the crux of this was the goal to administer end-to-end encryption across the whole messaging “ecosystem”. Ostensibly, this was part of…

The advent of mass working from home has made many people more aware of the security risks of sending sensitive information via the internet. The best we can do at the moment is make it difficult to intercept and hack your messages – but we can’t make it impossible. What we need is a new type of internet: the quantum internet. In this version of the global network, data is secure, connections are private and your worries about information being intercepted are a thing of the past. My colleagues and I have just made a breakthrough, published in Science Advances, that will…

The source code of the Windows XP operating system is now circulating online as a huge 43GB mega-dump. Although the software is nearly two decades old, it’s still used by people, businesses and organisations around the world. This source code leak leaves it open to being scoured for bugs and weaknesses hackers can exploit. The leaked torrent files, published on the bulletin board website 4chan, include the source code for Windows XP Service Pack 1, Windows Server 2003, MS DOS 3.30, MS DOS 6.0, Windows 2000, Windows CE 3, Windows CE 4, Windows CE 5, Windows Embedded 7, Windows Embedded CE,…

Amid the horrific public health and economic fallout from a fast-moving pandemic, a more positive phenomenon is playing out: COVID-19 has provided opportunities to businesses, universities and communities to become hothouses of innovation. Around the world, digital technologies are driving high-impact interventions. Community and public health leaders are handling time-sensitive tasks and meeting pressing needs with technologies that are affordable and inclusive, and don’t require much technical knowledge. Our research reveals the outsized impact of inexpensive, readily available digital technologies. In the midst of a maelstrom, these technologies — among them social media, mobile apps, analytics and cloud computing — help communities cope…

In the sci-fi novel “The Diamond Age” by Neal Stephenson, body art has evolved into “constantly shifting mediatronic tattoos” – in-skin displays powered by nanotech robopigments. In the 25 years since the novel was published, nanotechnology has had time to catch up, and the sci-fi vision of dynamic tattoos is starting to become a reality. The first examples of color-changing nanotech tattoos have been developed over the past few years, and they’re not just for body art. They have a biomedical purpose. Imagine a tattoo that alerts you to a health problem signaled by a change in your biochemistry, or to radiation…

The commodification of the internet in the early 1990s brought western societies into the digital age and has changed the way consumers interact with commercial enterprises. The digital industry companies have one thing in common: the use of the user’s personal data through technology to gain competitive advantage. Spotify, Amazon, eBay, Apple, Google Play: these corporations have reached a level of product and service customization never seen before. Spotify’s algorithm, for example, offers you artists and playlists based on your age, gender, location and listening history. Management researchers are interested in these new forms of commerce for two main reasons: they mark a break with…

Valentine’s Day was sweet, spring break was fun, then… boom! COVID-19. Stay-at-home orders, workplace shutdowns, school closures and social distancing requirements changed lives almost overnight. Forty-two percent of the U.S. workforce now works from home full-time. In the six months since the “new normal” began, Americans have gained a fair amount of experience with working, studying and socializing online. With schools resuming and cooler weather curtailing outdoor activities, videoconferencing will be as front and center as it was in the spring. As someone who researches and teaches instructional technology, I can offer recommendations for how to make the best of the situation…
