    How Digital DNA Could Help You Make Better Health Choices

    How Digital DNA Could Help You Make Better Health Choices

    What if you could know exactly how food or medication would impact your health -- before you put it in your body? Genomics researcher Jun Wang is working to develop digital doppelgangers for real people; they start with genetic code, but they'll also factor in other kinds of data as well, from food intake to sleep to data collected by a "smart toilet." With all of this valuable information, Wang hopes to create an engine that will change the way we think about health, both on an individual level and as a collective.

    How Do Sinkholes Form?

    How Do Sinkholes Form?

    Sinkholes form through both natural and human-made processes. Most of us think about erosion on the surface of the earth, but erosion can occur in the subsurface as well. In fact, scientist and engineers have a very creative name for just such a process: internal erosion. If just the right factors come together in the subsurface, some very interesting things can occur, including sinkholes.

    How Does a Spectrometer Work?

    How Does a Spectrometer Work?

    Take a look inside the optical bench of an Ocean Optics miniature spectrometer. In spectroscopy, photons encounter many components and undergo a variety of processes before registering as a spectrum. Let's see what happens to these photons once they enter the spectrometer!

    How Math Can Prepare New Generations for The Future

    How Math Can Prepare New Generations for The Future

    During the Cold War, Soviet educators were tasked with raising citizens who could out-innovate and out-build their American counterparts. One of their primary tools for doing so? Math. Educator Masha Gershman describes how the adaptive, highly social Soviet approach to teaching math can be deployed to prep new generations for an ever-shifting future.

    How Quantum Physics Can Make Encryption Stronger

    How Quantum Physics Can Make Encryption Stronger

    As quantum computing matures, it's going to bring unimaginable increases in computational power along with it -- and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there's still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he's fighting quantum with quantum: designing security devices and programs that use the power of quantum physics to defend against the most sophisticated attacks.

    How Quicksand Causes Dam Failures

    How Quicksand Causes Dam Failures

    In civil engineering, quicksand is more than just a puddle of mud! The "quick condition" occurs when seepage reduces the effective stress of a soil. This can lead to some dangerous conditions, especially if the seepage causes piping erosion to occur at a dam.

    How Soil Destroys Buildings

    How Soil Destroys Buildings

    Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.

    How Technology Can Reconnect Parents And Kids

    How Technology Can Reconnect Parents And Kids

    When children are separated from their parents -- whether due to migration, custody changes, incarceration or any number of other factors -- how can families maintain connection? Computer scientist Lana Yarosh showcases why it's important to design technology that empowers people to share meaningful interactions beyond a video chat or phone call, granting them the chance to reconnect despite life's big disruptions.

    How does land surveying work?

    How does land surveying work?

    This video explores a primer on one of the most important companions to civil engineering: land surveyors. Conventional measurement tools like a tape measure and protractor don't work for large civil structures and public works projects. Surveying is essentially the science of measuring big stuff. In this video I give a quick explanation of how surveying works and show a few ways you can do your own leveling survey at home. No sines, cosines, or tangents required!
