Where did we humans come from? When did we become the dominant species on the planet?

Experts take you on an exploration of the last half-decade of new evidence from ancient DNA, fossils, archaeology and population studies that has updated our knowledge about The Origins of Today's Humans.

UC San Diego professor of biology Justin Meyer, who specializes in infectious disease research presents his course The Evolution of Infectious Diseases with special attention to the SARS-CoV-2 virus, the COVID-19 disease and its pandemic spread throughout the world. In this second lecture he addresses ten questions about coronaviruses. Series: "The Evolution of Infectious Diseases with Justin Meyer" [Science] [Show ID: 35817]

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.

In times of stress, anxiety, and isolation finding effective strategies to understand our emotions and how we relate to the world at large often brings comfort. Mindfulness, meditation, and compassion have long been championed as helpful strategies but how do they impact our well being, if at all? Fadel Zeidan joins William Mobley to discuss his work applying scientific methods to these practices to quantify and discover how and why they work.
