Can you tell AI-generated people from real ones?
Can you tell AI-generated people from real ones?
Research shows survey participants duped by AI-generated images nearly 40 per cent of the time If you recently had trouble figuring out if an image of a person is real or generated through artificial intelligence (AI), you're not alone. A new study from University of Waterloo researchers found that people had more difficulty than was expected distinguishing who is a real person and who is artificially generated.

When CEOs admit they have failed, stock analysts value their companies more highly: UBC study
In business, leaders rarely want to take accountability for unfavourable company performance - but a new study from the UBC Sauder School of Business shows that when they do, they might actually boost the value of their companies. In the study titled " The role of CEO accounts and perceived integrity in analysts' forecasts ," researchers electronically combed through more than 35,000 CEO conference calls to investors that spanned 12 years (2002-2013), and looked at whether the companies performed favourably or unfavourably.

Researchers make a significant step towards reliably processing quantum information
Using laser light, researchers have developed the most robust method currently known to control individual qubits made of the chemical element barium. The ability to reliably control a qubit is an important achievement for realizing future functional quantum computers. This new method, developed at the University of Waterloo's Institute for Quantum Computing (IQC), uses a small glass waveguide to separate laser beams and focus them four microns apart, about four-hundredths of the width of a single human hair.

In your face
Pierrich Plusquellec and his team at UdeM's School of Psychoeducation publish the results of a facial-expression study measuring 'emotional contagion' and the risk of depression. Repeatedly exposed to negative emotions, relationship professionals such as social workers, psychologists and psychoeducators are at high risk of experiencing "emotional contagion," an unconscious, automatic transmission of an emotion from one individual to another.

How secure are voice authentication systems really?
Attackers can break voice authentication with up to 99 per cent success within six tries Computer scientists at the University of Waterloo have discovered a method of attack that can successfully bypass voice authentication security systems with up to a 99% success rate after only six tries. Voice authentication - which allows companies to verify the identity of their clients via a supposedly unique "voiceprint" - has increasingly been used in remote banking, call centers and other security-critical scenarios.

Can’t find your phone? There’s a robot for that
May 15, 2023 Robots can help find objects you've lost, thanks to new 'artificial memory' Engineers at the University of Waterloo have discovered a new way to program robots to help people with dementia locate medicine, glasses, phones and other objects they need but have lost. And while the initial focus is on assisting a specific group of people, the technology could someday be used by anyone who has searched high and low for something they've misplaced.
