The scientists cultivated coccolithophores, which create the greatest amounts of new calcium carbonate on the planet, and do so more quickly than coral reefs, using only sunlight, seawater, and dissolved carbon dioxide.How scientists hope to use algae-grown limestone to build citiesThe burning of limestone from quarries contributes significantly to the 7% of the yearly greenhouse gas emissions from the manufacturing of cement worldwide. A research team headed by the University of Colorado in Boulder has discovered a…

When cartilage in joints such as the knees gets damaged, it is very slow to heal – if it ever does at all. An experimental new biohybrid material could one day replace it, however, and may even promote the growth of new natural cartilage.One of the challenges in designing artificial cartilage lies in the fact that like its natural counterpart, the material must be malleable enough to bend with the joint, yet also tough enough to withstand the loads constantly placed upon it.In the past, substances made of natural polymers…

South Korea's SK Hynix has started using a high-tech material from a Korean supplier in its chipmaking process, a company official said on Wednesday, shifting away from a Japanese product for the first time.A SK Hynix official said it had selected an unnamed Korean company to supply high-purity hydrogen fluoride (HF), which is used in etching silicon materials and cleaning chips.South Korean chipmakers have been looking for ways to cut their reliance on Japanese materials since Japan imposed curbs on exports of key input…

One of the most mysterious astronomical objects, black holes are said to have an extreme gravitational pull which helps them suck in nearly everything that gets close to them, even light. While this has been known for long, scientists have recently made more fascinating observations while studying a star's encounter with a black hole. Besides the spaghettification process, where the black hole rips apart the star and stretches its material, the event also witnessed some intense wind flowing outward, sending the star's…

Researchers at the University of Cambridge have invented a soft, jelly-like material that can endure the equivalent of an elephant standing on it and not explode like a water balloon — even though it's 80 percent water. When the weight is removed, the material returns to its former shape completely without being permanently deformed. The material, described as “super jelly”, is as strong as a shatterproof glass. It could be employed in a variety of applications, including soft robotics, bioelectronics, and biological…

Last updated: July 12th, 2022 at 07:00 UTC+02:00 Google recently made a few changes to the Play Store’s UI elements, bringing Material You design to Chromebooks and tablets. Now, the company is bringing some more Material You elements to the Play Store for Android devices. When the Material You redesign first arrived on the Play Store in October, it updated the homescreen, search field, and bottom menu bar, and applied dynamic color to key elements. Now, as per 9To5Google, the latest Material You makeover of the Play…

For the first time, physicists have witnessed something incredibly exciting: electrons forming whirlpools just like a fluid.This behavior is one that scientists have long predicted, but never observed before. And it could be the key to developing more efficient and faster next-generation electronics.  "Electron vortices are expected in theory, but there's been no direct proof, and seeing is believing," says one of the researchers behind the new study, physicist Leonid Levitov from MIT. "Now we've seen it, and it's a…

Ever since last year, Google has been applying the Material You paint job to its apps and services. While the process is pretty much complete, there’s still a little bit more work to do. Now, according to 9To5Google, the Google Play Store for tablets and Chromebooks is getting Material You.Google introduced Material You last year. The company took its design and pulled a complete 180, giving us the more bubbly and rounded UI. It was even able to receive an iF Gold Design Award.Now, Material You is coming to the Play…

Nature is capable of producing materials of incredible strength, with spider silk one of the most celebrated examples. In 2015, a group of scientists made a game-changing discovery in this area, demonstrating that the teeth of clingy molluscs called limpets actually have the strongest tensile strength of any biological material. Drawing inspiration from these flinty fangs, the team has produced a composite biomaterial with extreme strength, which could provide a more sustainable alternative to high-performance materials…

The Anthropocene is the name some scientists are giving to the current geological epoch, marked by the point in time when human activity started having a significant impact on the geology and ecosystems of Earth – not least through climate change.  Now scientists think they have precisely determined the beginning of the Anthropocene through particular biomarkers – radioactive material discovered in marine sediments and corals in the northwest Pacific Ocean, off the coast of Japan.That material comes from atomic tests…
