    Return to Apollo: Geologic Evolution of a Young Moon

    Return to Apollo: Geologic Evolution of a Young Moon

    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 Moons mantle and crust formed contemporaneously between 4.33 and 4.38 billion years ago.

    Health in Space: Developing New Tools for the Trip to Mars

    Health in Space: Developing New Tools for the Trip to Mars

    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.

    Planetary Defense: Avoiding a Cosmic Catastrophe

    Planetary Defense: Avoiding a Cosmic Catastrophe

    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.

    Crossing the Blood Brain Barrier: One Byte at a Time

    Crossing the Blood Brain Barrier: One Byte at a Time

    The blood-brain-barrier (BBB) is a special structure in the body that helps to protect the brain from unwanted toxins and germs. Unfortunately, this barrier can also make it extremely difficult for therapeutics to reach their intended target within brain. Lawrence Livermore Lab scientists describe how combining experimental techniques with computational methods, making use of some of the fastest supercomputers in the world, can speed up the process of optimizing therapeutics to cross the BBB.

    3D Bioprinted Model for Metastatic Brain Tumors

    3D Bioprinted Model for Metastatic Brain Tumors

    Cancer becomes highly dangerous when it spreads from its original site to a different vital organ. These secondary tumors called metastases are what kill most patients. Despite hundreds of years of research, it is not understood why, where, and how cancer spreads to organs like the brain. Lawrence Livermore Lab scientist describes how they bring together cancer biology, 3D printing and material science, to understand and hopefully prevent metastases in the future.

    In the Mood: Deciphering Complex Brain Signals

    In the Mood: Deciphering Complex Brain Signals

    The human brain contains approximately 86 billion neurons, and 100 trillion connections between those neurons. Despite our inability to image each neuron and determine their exact connective patterns, several approaches for noninvasive imaging of the living brain have been developed and utilized to great benefit. LLNL scientist Alan Kaplan explores the immense landscape of the human brain and quantifies the brain in terms of data flow. Then describes engineering applications of recorded electrophysiological data and explores methods for analyzing such data to determine the pattern of signals that arise during various activities and mood states.
