How do you apply for college during a pandemic? What happens now that the ACT and SAT are canceled? Is it safe to go to college next year? Should I just take a gap year? There are so many unanswered questions creating unease for students and parents. Steven Mercer, EdD helps us all take a deep breath by sharing insight into how colleges will be approaching admissions for the next academic year as well as practical advice for high school juniors and seniors.

Without a classroom, where should students learn? Shelli Kurth and Nicole Assisi share tips for creating an effective space in your home with materials you have on hand. Series: "STEAM: Adding Arts to STEM Education" [Education] [Show ID: 35841]

New state-of-the-art chronologic measurements of rocks brought to Earth by Apollo astronauts reveal that many of the historical age determinations are erroneous. The new measurements presented by cosmochemist Lars Borg demonstrate that the Moon's mantle and crust formed contemporaneously between 4.33 and 4.38 billion years ago.

Limited medical equipment on space craft makes medical care in space a real challenge. Ordinary problems must be dealt with, as well as problems related to the unique environment of space. As NASA plans for new crewed exploration missions, beyond low earth orbit, telemedicine support will be limited, and medical evacuation to earth will no longer be possible. To address this problem, LLNL and NASA Ames Research Center are developing a novel diagnostic instrument to help provide medical care on deep space missions. The technology consists of a blood analysis system, based on microfluidics, together with a breath analysis system that uses carbon nanotube sensors. The technology is designed to support future missions to the moon and Mars, and it is expected to be used for terrestrial medicine as well, in a variety of arenas where medical resources are limited.

Our planet has been continually bombarded by asteroids since its formation, 4.5 billion years ago. While the frequency of large impacts has decreased, many potential Near-Earth Object threats remain undiscovered, so if or when they will impact Earth remains unknown. Fortunately, if an Earth-threatening asteroid is discovered in time, there are ways to mitigate or even prevent a disaster. Scientists at LLNL provide computer simulations in preparation these scenarios so if the time comes where an asteroid is headed our way, we will be prepared.

Exploring the undersea world has always presented challenges in terms of cost and accessibility. However, recent advances in ocean observing technology are allowing researchers to explore heretofore unexplored worlds at reasonable cost. Join oceanographer Jules Jaffe as he describes his career as an ocean explorer and technology innovator. Learn how new, cost effective instruments and platforms present unprecedented opportunities for students of all ages to engage in designing, building and experimenting with ocean observing technologies with examples from underwater robots and underwater microscopes.

An internationally celebrated American novelist, short story writer, poet, and activist, Walker's work has been translated into more than two dozen languages, and her books have sold more than fifteen million copies. She wrote The Color Purple, for which she won the National Book Award for hardcover fiction, and the Pulitzer Prize for Fiction. Walker's collected work includes poetry, novels, short fiction, essays, critical essays, and children's stories. She was the recipient of a Rosenthal Foundation award and an American Academy and Institute of Arts and Letters award for In Love and Trouble.

Social media and big data can have important practical applications in public health, disaster management, transportation, and urban planning. Data scientists are using machine learning algorithms, computer vision, and natural language processing to collect and analyze social media data (such as Facebook and YouTube) and environmental sensor/camera data to study human communications and movements. These big data technologies can be powerful tools to predict short-term future events, such as flu outbreaks, severe air pollution, traffic congestion, the weather, and patterns of disaster evacuation. At the same time, these technologies monitor users’ digital footprints, opinions and geolocations. Ming-Hsiang Tsou, PhD discusses the challenges in social media analytics, including data noise and biases, fake news, and data privacy.
