How to Make Electric Cars Cheaper? Something as Thin as Hair May Hold the Secret.

Scientists are rushing to make electric cars more accessible to people of all financial brackets. What can this new manipulation of nanomaterials do to help that? Also, geoengineering to cool down our planet sounds like an attractive idea due to global warming, but what are the benefits and pitfalls of geoengineering Earth’s climate? And how can a 3-D printer create scaffolding fit for biological cultures? That and more in this week’s Tech News 4 Kids newsletter! Join our classes to learn more about the latest technologies — coding, artificial intelligence, and more.

Electric cars just might be the future of transportation, but most on the market right now are pricey. Luckily, scientists are working hard to change that! In fact, it was just discovered that using nanomaterials as thin as hair just might be the key to creating much cheaper electric cars. But how does that work? Learn all about these small, flexible materials here!

Earth has been steadily warming, and evidence shows that humans are largely to blame. In order to combat this steady rise in temperature, scientists have been exploring different methods that might help cool down our planet. One of these methods includes geoengineering, but it’s unclear whether it is a good thing. Learn all about the fascinating technologies that scientists have been looking into here!

3-D Printers Create Scaffolding Fit for Biological Cultures

A new printing system has been created, and it looks like biological cultures are at the center. A new 3-D printer can create mesh-like scaffolding with threads thinner than a strand of hair. As it turns out, this type of structure is perfect for growing certain cultures in a very uniform way. It’s still very new, but it has a lot of scientists excited. Check out this unique new printer here!
