AI Is Starting To Understand Us, But How Well Do We Understand AI?


Artificial intelligence (AI) still often overpromises and underdelivers, but we are seeing AI begin to understand us and adoption has accelerated rapidly. Are we prepared for what is coming?

New 3D printable phase-changing composites can regulate temperatures inside buildings


Changing climate patterns have left millions of people vulnerable to weather extremes. As temperature fluctuations become more commonplace around the world, conventional power-guzzling cooling and heating systems need a more innovative, energy-efficient alternative, and in turn, lessen the burden on already struggling power grids.

 

In a new study, researchers at Texas A&M University have created novel 3D printable phase-change material (PCM) composites that can regulate ambient temperatures inside buildings using a simpler and cost-effective manufacturing process. Furthermore, these composites can be added to building materials, like paint, or 3D printed as decorative home accents to seamlessly integrate into different indoor environments.

 

“The ability to integrate phase-change materials into building materials using a scalable method opens opportunities to produce more passive temperature regulation in both new builds and already existing structures,” said Dr. Emily Pentzer, associate professor in the Department of Materials Science and Engineering and the Department of Chemistry. Dr. Emily Pentzer and her team have created novel 3D printable phase-change material composites that can regulate ambient temperatures inside buildings using a simpler and cost-effective manufacturing process.

 

This study was published in the June issue of the journal Matter. Heating, ventilation and air conditioning (HVAC) systems are the most commonly used methods to regulate temperatures in residential and commercial establishments. However, these systems guzzle a lot of energy. Furthermore, they use greenhouse materials, called refrigerants, for generating cool, dry air. These ongoing issues with HVAC systems have triggered research into alternative materials and technologies that require less energy to function and can regulate temperature commensurate to HVAC systems.

 

One of the materials that have gained a lot of interest for temperature regulation is phase-change materials. As the name suggests, these compounds change their physical state depending on the temperature in the environment. So, when phase-change materials store heat, they convert from solid to liquid upon absorbing heat and vice versa when they release heat. Thus, unlike HVAC systems that rely solely on external power to heat and cool, these materials are passive components, requiring no external electricity to regulate temperature.

Surface of Jupiter’s Moon Europa Churned by Small Impacts


Jupiter’s moon Europa and its global ocean may currently have conditions suitable for life. Scientists are studying processes on the icy surface as they prepare to explore.

 

Jupiter’s icy moon Europa and its global ocean may currently have conditions suitable for life. Scientists are studying processes on the icy surface as they prepare to explore. It’s easy to see the impact of space debris on our Moon, where the ancient, battered surface is covered with craters and scars. Jupiter’s icy moon Europa withstands a similar trouncing – along with a punch of super-intense radiation. As the uppermost surface of the icy moon churns, material brought to the surface is zapped by high-energy electron radiation accelerated by Jupiter.

 

NASA-funded scientists are studying the cumulative effects of small impacts on Europa’s surface as they prepare to explore the distant moon with the Europa Clipper mission and study the possibilities for a future lander mission. Europa is of particular scientific interest because its salty ocean, which lies beneath a thick layer of ice, may currently have conditions suitable for existing life. That water may even make its way into the icy crust and onto the moon’s surface.

 

The new study, which was published July 12, 2021 in the journal Nature Astronomy, is a bit more pessimistic. In it, researchers modeled how Europa’s surface is disturbed by small but frequent impacts — a real issue for a world without a substantial atmosphere to burn up incoming hunks of rock and ice.
 

They found that such “impact gardening” likely churns the top 12 inches (30 cm) or so of Europan ice significantly, bringing previously buried bits up to the surface, where radiation can zap any interesting molecules into unrecognizable goo. “If we hope to find pristine, chemical biosignatures, we will have to look below the zone where impacts have been gardening,” study lead author Emily Costello, a planetary research scientist at the University of Hawaii at Manoa, said in a statement. “Chemical biosignatures in areas shallower than that zone may have been exposed to destructive radiation.”

 

Previous work has suggested that just 8 inches (20 centimeters) of ice could likely shield any biomolecules that might exist on Europa from that punishing radiation environment, even in the hardest-hit regions of the moon.
