Scientists In Switzerland Use Sound Waves To Levitate, Manipulate Matter. Http://bit.ly/15z86Ro As Anyone
Scientists in Switzerland use sound waves to levitate, manipulate matter. http://bit.ly/15z86Ro As anyone with a subwoofer and a teenager knows, sound waves exert pressure. When those waves are bounced between carefully aligned surfaces, they can create what is known as a standing wave, in which the total pressure from the original wave and its reflection cancel each other out. Objects placed at spots along the wave with the lowest amplitude, known as node points, tend to stay put. Being able to manipulated matter without touching it promises a wealth of applications, from material sciences to biology. For instance nucleic acids can be introduced into cells – a process known as DNA transfection – without fear of contamination."You can basically play with cells in a droplet," says Foresti While commuting via acoustically levitated skateboards may be far off in the future, Foresti says that he hopes that other researchers will soon find novel uses for his method.

Reptiles and things...this is the Titanoboa! They are calling this one of the greatest discoveries since the T-Rex! Discovered in a Colombian coal mine, its believed to have lived 59 million years ago, was 49 feet long, two feet wide, and weighed 2,500 lbs! Check out this awesome site from the Smithsonian Channel and learn more about the Titanoboa (there's even a cool Monster Snake Game there too!) Have FUN!: http://bit.ly/19sXMjB (p.s. I had my feet up while I was typing that...does anyone else get the HEEBIE-JEEBIES when it comes to snakes?)
Presented in partnership with @PopularMechanics magazine, this month's groovy box "What's The Matter?" is all about ice and the #StatesOfMatter. Sign up for May's monthly subscription to ensure you get this groovy box for the #STEMist in your life. Pull a wire through a block of ice? This trick works thanks to a groovy phenomenon called 'regelation', in which ice melts from the pressure applied by a wire and freezes again when the pressure is reduced. #regelation What's Happening? The balloon ice weights pull the copper wire through the block of ice. The pressure applied by the weights forms a liquid directly under the copper wire. As the wire travels downward the liquid refreezes above the wire and forms back into a solid. This is similar to ice skating where the blades of a skater melt the ice directly underneath, allowing the skater to move smoothly on a thin layer of water. #STEMists do the "E" in STEM!

Academics in a Box Inc. was founded to inspire in students a desire to learn more about the sciences and humanities. Our products aim to allow students a new way to experience the beauty, poetry, and wonder of our universe through hands-on experience. Our foundation is based on the ideas that by “doing” and “experiencing,” students are more motivated to become inquisitive about the world around them. It’s this curiosity and creative thinking that are at the heart of developing a love of learning. The Next Generation Science Standards (NGSS) is used as a guide to ensure that our products supplement the learning that takes place in the classroom. We aim to take students beyond simple memorization of facts and figures by helping them gain a better understanding of significant science, technology, engineering, and mathematics (STEM) practice and application, as well as gain a deeper appreciation of the materials they are presented with.
