Progressive localization of deformation is a basic mechanical process that produces simultaneously reduced strength and increasing strain in a deforming rock volume. The localization framework describes the progressive evolution of deformation from distributed failures in a rock volume to localized shear zones, culminating in generation of primary slip zones and ...

Imaging quantum spin liquid behavior in single-layer 1T-TaSe2 - LivestreamQuantum spin liquids (QSLs) are a novel state of matter predicted to arise in quantum antiferromagnets where magnetic frustration or quantum fluctuations are strong enough to prevent magnetically ordered states even down to the lowest temperatures. QSLs are believed to exist in strongly correlated Mott insulators, and are thus related ...
Why do falling cats always land on their feet? The question has long intrigued humans. In this talk, we explore how the solution stumped brilliant minds and how it helped solve other seemingly impossible puzzles. With numerous photos and videos, physicist and cat parent Greg Gbur explores how attempts to ...

Programmable light-matter interactions: DNA as a tool for nanophotonics - LivestreamLight can be created, scattered, and confined by nanoparticles whose dimensions are smaller than the wavelength of light. A nanoparticle's interaction with light is often strongly tuned by its size and shape, providing an exciting opportunity to control the fate of photons with extraordinary precision. However, harnessing this potential is ...
Recent years have seen unprecedented motivation for the emergence of new energy technologies. Global dependence on fossil fuels, however, will persist until alternate technologies can compete economically. We must develop means to produce energy (or energy carriers) from renewable sources and then convert them to work as efficiently and cleanly ...
Financial interests distort the truths of evidence-based medicine, says Dr. Leemon B. McHenry. By revealing previously confidential documents released in litigation, Dr. McHenry exposes the role that pharmaceutical marketing has in the construction of medical literature, conference presentations and continuing medical education. The marketing spin is designed to be indistinguishable ...
For nearly four decades, satellites showed Antarctic sea ice had been slowly expanding in horizontal extent. Over the same period Arctic sea ice extent decreased rapidly, by nearly half the extent seen in the first images from modern satellite sensors. The decline in Arctic sea ice extent is roughly proportional ...
“Life is a process, not a substance, and it is necessarily temporary. We are not the reason for the existence of the universe, but our ability for self-awareness and reflection makes us special within it.†― Sean CarrollSean Carroll is a Research Professor of theoretical physics at the California Institute ...
How do scientists go from OMG to PhD? How do they turn their passion for science into their profession? What advice do they have for future scientists?If you are a 5th-12th grade student, undergraduate, teacher or parent, join us to ask these questions and more in a Q&A session with ...
A New Force of Nature at the Large Hadron Colider - LivestreamAt the end of March 2021, scientists working on the LHCb experiment at CERN in Geneva reported an unusual discrepancy in their data that caused huge excitement in the physics community and beyond. They looked at a decade of information about how unstable particles called B mesons decayed into electrons ...

A New Theory of Adversarial Examples in Machine Learning - LivestreamThe extreme fragility of deep neural networks when presented with tiny perturbations in their inputs was independently discovered by several research groups in 2013. Due to their mysterious properties and major security implications, these adversarial examples had been studied extensively over the last eight years, but in spite of enormous ...
Molecular Dynamics Simulations of Clathrate Hydrates - LivestreamClathrate hydrates are ice-like inclusion compounds in which space-filling water cages encapsulate different molecular substances. Dr. Saman Alavi studies clathrate hydrate materials using molecular dynamics simulations. In this talk, an introduction to these substances will be given with examples of how molecular dynamics simulations can give insights into details of ...
  The Frank Drake Award of the non-profit SETI Institute celebrates outstanding contributions to the scientific study of the origin, nature, and prevalence of life in the universe, and for work on techniques for the discovery of the existence of such life. (Past winners have included Nobel Laureate Charles Townes, and ...
