To address the growing threat of cyberattacks on industrial control systems, a KAUST team including Fouzi Harrou, Wu Wang and led by Ying Sun has developed an improved method for detecting malicious intrusions.

Internet-based industrial control systems are widely used to monitor and operate factories and critical infrastructure. In the past, these systems relied on expensive dedicated networks; however, moving them online has made them cheaper and easier to access. But it has also made them more vulnerable to attack, a danger that is growing alongside the increasing adoption of internet of things (IoT) technology.

Conventional security solutions such as firewalls and antivirus software are not appropriate for protecting industrial control systems because of their distinct specifications. Their sheer complexity also makes it hard for even the best algorithms to pick out abnormal occurrences that might spell invasion.

Artificial intelligence has reached a point where it can compose text that sounds so human that it dupes most people into thinking it was written by another person. These AI programs—based on what are called autoregressive models—are being successfully used to create and deliberately spread everything from fake political news to AI-written blog posts that seem authentic to the average person and are published under human-sounding byline.

However, though autoregressive models can successfully fool most humans, their capabilities are always going to be limited, according to research by Chu-Cheng Lin, a Ph.D. candidate in the Whiting School of Engineering’s Department of Computer Science.

“Our work reveals that some desired qualities of intelligence—for example, the ability to form consistent arguments without errors—will never emerge with any reasonably sized, reasonably fast autoregressive model,” said Lin, a member of the Center for Language and Speech Processing.

Walmart has launched an instant drone delivery system for customers living within a 50-mile radius of its headquarters in northern Arkansas.

The retail giant has partnered with drone company Zipline to launch the new system that will offer on-demand delivery for health and wellness and consumable items within 50 miles of the Walmart Neighborhood Market in Pea Ridge, according to a press release.

“It’s unbelievably exciting, we’ve been working towards this day for many many years,” Zipline’s CEO Liam O’Connor told CBS News.

Astronauts on the International Space Station plan a “turkey trot” and some special food in honor of U.S. Thanksgiving on Thursday (Nov. 25).

Five astronauts of the seven-person Expedition 66 crew gathered to film a YouTube video released Monday (Nov. 22) by NASA’s Johnson Space Center about how they will celebrate the holiday while in orbit.

Blue Origin has announced its next suborbital space flight for December and it includes two special guests among the crew of six.

Keisha S., a health and energy coach from the Caribbean nation of Antigua and Barbuda, just won a free trip to suborbital space with Virgin Galactic.

Just as a voltage difference can generate electric current, a temperature difference can generate a current flow in thermoelectric materials governed by its “Peltier conductivity” ℗. Now, researchers from Japan demonstrate an unprecedented large P in a single crystal of Ta₂PdSe₆ that is 200 times larger than the maximum P commercially available, opening doors to new research avenues and revolutionizing modern electronics.

We know that current flows inside a metallic conductor in presence of a voltage difference across its ends. However, this is not the only way to generate current. In fact, a temperature difference could work as well. This phenomenon, called “Seebeck effect,” laid the foundation of the field of thermoelectrics, which deals with materials producing electricity under the application of a temperature difference.

Similar to the concept of an electrical conductivity, thermoelectricity is governed by the Peltier conductivity, P, which relates the thermoelectric current to the temperature gradient. However, unlike its electrical counterpart, P is less explored and understood. For instance, is there a theoretical upper limit to how large P can be? Far from being a mere curiosity, the possibility of a large P could be a game changer for modern-day electronics.

With feature updates galore, paradigm-changing DDR5 memory, and much more, the technology backing Intel’s 12th Generation Core CPUs is just as interesting as the chips themselves. We’ve got a breakdown.
