Could ‘hot carrier’ solar cells break the theoretical efficiency limit?

Posted by in categories: solar power, sustainability

Up to 50% of the energy absorbed by a solar cell is lost as heat. Scientists are now developing a third generation of “hot carrier” solar cells that take advantage of this heat, potentially breaking the Shockley-Queisser limit of silicon-based PV.

Second FAA BVLOS drone operations waiver for Iris Automation

Posted by in categories: drones, robotics/AI

The FAA has granted Iris Automation a second waiver for Beyond Visual Line of Sight (BVLOS) autonomous drone operations on behalf of the City of Reno. But while the previous waiver required the use of Iris Automation’s advanced detect and avoid solution Casia X, this one utilizes the company’s Casia G ground-based solution (pictured above).

The fresh waiver allows an operator to fly without the need for visual observers or the Remote Pilot in Command to maintain visual contact with the drone. Casia G uses Iris Automation’s patented detect and avoid technology to create a stationary perimeter of sanitized, monitored airspace, enabling drones to complete missions safely. The system also provides awareness of intruder-piloted aircraft to maneuver drones to safe zones.

Nanoengineered bacteria provide light-activated cancer therapy

Posted by in categories: bioengineering, biotech/medical

Cancer cells thrive by competing with normal cells for survival. Now, researchers are employing living bacteria to fight back against the cancer. This so-called bacteriotherapy – the deployment of bacteria to fight cancer – has sparked interest in the fields of immunotherapy and bioengineering.

The AI Supremacy: Who Will Take the Lead in this Global Race?

Posted by in categories: economics, robotics/AI

Artificial intelligence is a target for every existing industry Or is it just another hyped innovation? It comes with no surprise how AI today becomes a catchall term that is said out loud in the job market. The US and China are in nip and tuck in the AI race for supremacy. Although China aims to be the technology leader by 2030, the economy is still at a struggle phase with a slowdown and trade war with the US. Emerging trends in artificial intelligence (AI) significantly points toward having a geopolitical disruption in the foreseeable future. As much as the fourth industrial revolution augmented the rise of advanced economies, so will machine learning and artificial intelligence transform the world.

New method compares machine-learning model’s reasoning to that of a human

Posted by in categories: biotech/medical, robotics/AI

In machine learning, understanding why a model makes certain decisions is often just as important as whether those decisions are correct. For instance, a machine-learning model might correctly predict that a skin lesion is cancerous, but it could have done so using an unrelated blip on a clinical photo.

While tools exist to help experts make sense of a model’s reasoning, often these methods only provide insights on one decision at a time, and each must be manually evaluated. Models are commonly trained using millions of data inputs, making it almost impossible for a human to evaluate enough decisions to identify patterns.

Now, researchers at MIT and IBM Research have created a method that enables a user to aggregate, sort, and rank these individual explanations to rapidly analyze a ’s behavior. Their technique, called Shared Interest, incorporates quantifiable metrics that compare how well a model’s reasoning matches that of a human.
