Researchers have observed the formation of 2D ice on gold surfaces that were thought to be too hydrophilic and too rough to support this type of ice.

Mobile devices use facial recognition technology to help users quickly and securely unlock their phones, make a financial transaction or access medical records. But facial recognition technologies that employ a specific user-detection method are highly vulnerable to deepfake-based attacks that could lead to significant security concerns for users and applications, according to new research involving the Penn State College of Information Sciences and Technology.

Mobile devices use facial recognition technology to help users quickly and securely unlock their phones, make a financial transaction or access medical records. But facial recognition technologies that employ a specific user-detection method are highly vulnerable to deepfake-based attacks that could lead to significant security concerns for users and applications, according to new research involving the Penn State College of Information Sciences and Technology.

The researchers found that most application programming interfaces that use facial liveness verification—a feature of facial recognition technology that uses computer vision to confirm the presence of a live user—don’t always detect digitally altered photos or videos of individuals made to look like a live version of someone else, also known as deepfakes. Applications that do use these detection measures are also significantly less effective at identifying deepfakes than what the app provider has claimed.

“In recent years we have observed significant development of facial authentication and verification technologies, which have been deployed in many security-critical applications,” said Ting Wang, associate professor of information sciences and technology and one principal investigator on the project. “Meanwhile, we have also seen substantial advances in deepfake technologies, making it fairly easy to synthesize live-looking facial images and video at little cost. We thus ask the interesting question: Is it possible for malicious attackers to misuse deepfakes to fool the facial verification systems?”

The 200-megapixel ISOCELL HP1 sensor uses advanced levels of pixel binning technologies to extract details and light in challenging situations.

“Hello, we’ve been trying to reach you about your car’s extended warranty.” After years of seemingly unstoppable scam robocalls, this phrase is embedded into the minds of many of us. Last month the Federal Communications Commission (FCC) announced it was ordering phone providers to block any calls coming from a known car warranty robocall scam, offering hope that U.S. phone users may hear that all-too-familiar automated voice a little less often.

But there is more work required to crack down on these calls. After all, car warranty warnings are only one type of scam. To understand how robocallers reach us, and why it’s so hard to stop them, Scientific American spoke with Adam Doupé, a cybersecurity expert at Arizona State University.

An Israeli startup is using over-the-phone voice analysis to detect atrial fibrillation, a common heart condition that is hard to find on a standard screening ECG.

Possibilities Are Endless — iHLS.

A new type of technology has recently been developed. AI technology that mimics the human eye. Researchers at the University of Central Florida have created a device for AI that replicates the retina of the eye. This new discovery can lead to AI that can immediately identify objects, such as automated descriptions of photos captured with a camera or a phone. This technology can potentially be used in autonomous robots and self-driving cars as well.

Circa 2019 😀 What a fun mind controlled toy drone 😗

How much more fun could drones be if you got fiddly hand controllers out of the way and flew them with your mind? That’s the question EEGSmart poses with its UDrone mini-quad, which responds to brainwaves and head movements instead of thumbsticks. It’s not perfect, but it does give a glimpse of a mind-controlled future.

Smartphone ownership (85%) and home broadband subscriptions (77%) have increased among American adults since 2019 – from 81% and 73% respectively. Though modest, both increases are statistically significant and come at a time when a majority of Americans say the internet has been important to them personally. And 91% of adults report having at least one of these technologies.

A Pew Research Center survey of U.S. adults conducted from Jan. 25 to Feb. 8, 2021, also finds that some Americans have difficulties when trying to go online. Some 30% of adults say they often or sometimes experience problems connecting to the internet at home, including 9% who say such problems happen often. Still, a majority of Americans say these connection troubles occur rarely (41%) or never (21%).

While there has been slight growth in the share who say they subscribe to high-speed internet, about a quarter of the population still does not have a broadband internet connection at home. And broadband non-adopters continue to cite financial constraints as one of the most important reasons why they forgo these services. Among non-broadband users, 45% say a reason why they do not have broadband at home is that the monthly cost of a home broadband subscription is too expensive, while about four-in-ten (37%) say the same about the cost of a computer. Beyond cost barriers, a little fewer than half of non-users cite having other options for internet access or the fact that their smartphone does everything online they need as a reason why they do not have a high-speed internet connection at home.
