Chelsey Juarez UC Santa Cruz Forensic Identification on: KQED-Quest QUEST visits the lab of Chelsey Juarez, a UC Santa Cruz doctoral candidate in forensic anthropology, who has developed a novel technique using chemical isotopes to help identify the remains of migrants who die crossing the U.S.-Mexico border. Use this educator guide to incorporate this story into your chemistry class and find resources for additional lessons on forensic science.
Robots battle it out on soccer field on: Yahoonews The Australian football team may have found a little wanting when playing in last year's World Cup, but when it comes to the robotic version of the event, they're the champions.
Flying Over Spirit's Work Site on: Jet Propulsion Laboratory Images of the 'Columbia Hills' region inside Mars' Gusev Crater, taken by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter, provided detailed, three-dimensional information that was used to create this animation of a hypothetical flyover. NASA's Mars Exploration Rover Spirit has been exploring this range of hills since 2004.
Walter Kohn University of California Interview on: The Vega Science Trust Walter Kohn is a condensed matter theorist who has made seminal contributions to the understanding of the electronic structure of materials. He played the leading role in the development of density functional theory, which has revolutionized scientists' approach to the electronic structure of atoms, molecules and solid materials in physics, chemistry and materials science. He received the Nobel prize for chemistry for this work in 1998.
David Deutsch Oxford University The Fabric of Reality and parallel worlds on: TEDtalks Legendary physicist David Deutsch is author of The Fabric of Reality, and the leading proponent of multiverse theory, the astounding idea that our universe is constantly spawning parallel worlds. (Recorded July 2005 in Oxford, UK. Duration: 19:45)
An Ecologist in Space: The Earth from 240 Miles Up on: UC Berkeley Webcasts Dr. Piers Sellers, trained as an Earth scientist, was an astronaut on the STS-112 mission to the International Space Station in October 2002 and did three space walks. He will show video and photos of the Earth from space. He will also reflect on his personal experience as an astronaut and an earth scientist.
Kathleen Dudzinski Dolphin Communication Project Eavesdropping on Dolphins on: WGBH Forum Following a screening of the IMAX Film Dolphins, Dr. Kathleen Dudzinski, Director of the Dolphin Communication Project at Mystic Aquarium & Institute for Exploration, presents details from her 14 years of studying dolphin communication in the Bahamas, Japan and Honduras.
Jane Goodall Jane Goodall Institute for Wildlife Research Jane Goodall speaks at Google on: Google Video In the summer of 1960, 26-year-old Jane Goodall arrived on the shore of Lake Tanganyika in East Africa to study the area's chimpanzee population. The trip meant the fulfillment of Jane Goodall's childhood dream. In 1977, Jane founded the Jane Goodall Institute for Wildlife Research, Education and Conservation to provide ongoing support for field research on wild chimpanzees. Today, the mission of the Jane Goodall Institute is to advance the power of individuals to take informed and compassionate action to improve the environment for all living things. The Institute is a leader in the effort to protect chimpanzees and their habitats and is widely recognized for establishing innovative community-centered conservation and development programs in Africa and the Roots & Shoots education program in more than 70 countries.
Paul Davies Imperial College Black Holes, Wormholes and Time Travel on: The Vega Science Trust The idea of time travel makes great science fiction, but can it really be achieved? Paul Davies, visiting Professor in Physics at Imperial College, describes wormholes in space and other ways that might allow travel into the past or future.
Neal Weiner New York University Neutrino Mass and Dark Energy on: Fermilab Colloquium Lectures Two of the most exciting discoveries of recent years are the evidence for the accelerated expansion of the universe, and the existence of nonzero neutrino mass. The similarity of energy scales involved prompts us to question what relationships might exist between these two discoveries. We will explore how such a connection might arise, and how such a theory might be tested, both terrestrially, with future neutrino oscillation experiments, and with cosmology.
Pixels and Me on: Computers have revolutionized image media. Richard Lyon, one of the current pioneers of digital cameras, has found that several generations of pioneers in this field have been entangled with the terms picture element and pixel and that studying the history of the terminology is a fruitful approach to the history of the people and technology. Vladimir Zworykin's television research group at RCA popularized the term picture element in the 1930s, while the TV researchers at Bell Labs ignored that term, preferring image element. Fred Billingsley and others at the Jet Propulsion Laboratory developed computerized image processing and propagated the term pixel in the 1960s, while image processing researchers at Bell Labs ignored that term, preferring pel. In the early 1970s, pixel was spread through computer image processing publications from NASA, USC, IBM, Stanford, University of Missouri, and other places, eventually coming to be applied to elements of image sensor hardware, such as Lyon's optical mouse in 1980 and digital camera sensors more recently. Many of the people involved in this complex history have provided their personal recollections and documents to help piece the story together, and more such inputs will be solicited from the Computer History Museum audience.
