Efficient electrocatalysts, which are needed for the production of green hydrogen, for example, are hidden in materials composed of five or more elements. A team from Ruhr-Universität Bochum (RUB) and the University of Copenhagen has developed an efficient method for identifying promising candidates in the myriad of possible materials. To this end, the researchers combined experiments and simulation.

They published their report in the journal Advanced Energy Materials (“Unravelling Composition–Activity–Stability Trends in High Entropy Alloy Electrocatalysts by Using a Data-Guided Combinatorial Synthesis Strategy and Computational Modeling”).

The Firefox browser has stopped working due to a technical issue, with sites failing to load and no status information being provided to users.

The issue appears to be due to a HTTP3 problem. It appears that a recent update to the browser triggers an infinite loop in the network thread that prevents any pages from loading, leaving the browser useless.

However, this is an issue that can be temporarily overcome.

What are epinutrients, you ask? Allow us to explain.

In a 2021 study, naturopathic doctor and functional medicine expert Kara Fitzgerald, N.D., author of Younger You, was able to improve participants’ biological age by three years. Sounds like a tall order, but the intervention was actually pretty simple: With a very doable diet and exercise plan, it only took eight weeks to see these results. “A big reason we actually made a difference in eight weeks’ time is because we very intentionally bathed the body in a high amount of epinutrients,” she says on this episode of the mindbodygreen podcast.

What are epinutrients, you ask? Allow Fitzgerald to explain below, along with a few of her favorites.

Last year, Germany spent $53 billion on defense. This year, TSMC is spending $44 billion on chip factories. (In 2019, TSMC only spent $14.9 billion, so they are spending insane amounts of money trying to fix the chip shortage.) Pretty much everyone in the chip business is also dramatically increasing their spending as well.

TSMC investment will “put a ceiling” on Samsung, Intel’s foundry plans.

A new smart type of food packaging promises to eliminate food poisoning by killing harmful bacteria.

According to scientists, the packaging destroys hazardous bacteria like E.coli, Salmonella, and Listeria, allowing meat, fish, fruit, and vegetables to last longer.

“Food safety and waste have become a major societal challenge of our times with immense public health and economic impact which compromises food security. One of the most efficient ways to enhance food safety and reduce spoilage and waste is to develop efficient, biodegradable non-toxic food packaging materials,” Philip Demokritou of Harvard Chan School, who co-led the work, said in a statement.

Italian design outfit Lazzarini Design Studio is known for its larger-than-life concepts that give us a deep dive of transportation in the future. Their new concept design breaks all the confined barriers of propulsion on water and in the air, taking things to the next level with the Air Yacht.

This compressed helium-powered flying yacht (yes, an airborne yacht!) is targeted towards private owners who will stop at nothing, and push the envelope of adventure – laden in luxury and style. The mega yacht (or should I say a big catamaran) measuring 492 feet will be a revolution in the aviation industry with its twin airships filled with helium. These gigantic airships will be connected via a central carbon deck measuring 33 feet wide consisting of a master cabin, living area, and a large dining section. The outer edges of the airship have five en suite staterooms each, so taking along best buddies for the adventure of their lifetime is certain.

What is concept drift?

Concept drift occurs when there are changes in the distribution of the training set examples.

At the most basic level, concept drift causes data points that were once considered an example of one concept to be seen as another concept entirely over time.

For instance, fraud detection models are at risk for concept drift when the concept of fraud is constantly changing.

This can cause model performance to degrade, especially over extended periods where concept drift continues to occur without being detected by your monitoring systems.
