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.

Richard F. Lyon

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.

Insights into the Origins of Human Brain Tumors
on: Caltech
Houman Hemmati, a graduate student in biology at Caltech, discussed the recent advances in leukemia research that have identified bone marrow-derived stem cells as a source for brain-tumor cancers. Based on this work, scientists have taken a novel approach to identifying the origins of brain tumors. Their findings suggest that targeting tumor-derived stem cells is a promising approach to treating brain tumors.

Diffusion-Mediated Regulation In Endocrine Cell Networks
on: Caltech
Donald S. Cohen, Charles Lee Powell Professor of Applied Mathematics, Emeritus, Caltech; Danny Petrasek, Senior Research Fellow, Applied and Computational Mathematics, Caltech; and William Goodman, Professor of Medicine, UCLA, presented this lecture as part of the 0.1 Seminar series. They discuss a computational model that demonstrates diffusion-mediated regulation and that shows qualitative agreement with published experimental results. Such a signaling mechanism may regulate other networks with similar biochemical and geometric properties.

Maximum Likelihood Estimation for a Gene Regulatory Network Defined by Differential Equations
on:
Gene regulation may be described by a set of deterministic differential equations describing the time rate evolution of the gene product concentrations, and containing parameters accounting for the regulatory relationships occurring in the gene network. We will present maximum likelihood based estimators of the parameters arising in this formalism and we will prove that they have desirable properties. Our results may be applied to a gene regulation model yielding the early Drosophila segments formation relying on a statistical modelling of gene expression data obtained by confocal laser scanning microscopy. The proposed statistical model accounts for the uncertainty in the measurement of gene expression and the uncertainty in the time at which the measurements are performed.

Robert Walsh

Living with a Star-an encounter with Robert Walsh
on: sciencelive
Currently Robert is a Senior Lecturer in Astrophysics and Mathematics at the University of Central Lancashire, Preston, UK. His area of research is Solar Physics, where he uses space-based solar observatories (solar observing satellites) to monitor our closest star and then set-up sophisticated super-computer simulations to try and reproduce what we observe. He is married to Heather and has two children, Matthew (aged three) and Emma (aged 6 weeks).

Harlan Anderson

The Mouse That Roared: PDP-1 Celebration Event
on:
Introduced in 1959, the DEC PDP-1 computer is truly the mouse that roared, a powerful, easy-to-operate computer with a host of new abilities that allowed its users to interact with a computer all to themselves. This was a novelty in the early 1960s when mainframe-based batch processing was the norm and the idea of a computer dedicated to a single-user was heretical, akin to having a personal aircraft carrier.

Besides being a lot of fun to play, video games are also a major driver of innovation in computer graphics. Join us for a fascinating evening with three famous game designers -- Jordan Mechner (Prince of Persia), Rand Miller (Myst), and Will Wright (SimCity) . who will discuss how their games have pushed the boundaries of graphics development over the years. Moderated by Vince Broady of CNET GameSpot, the panelists will show and tell how their games have helped move us from simple pixel painting to lavish 3-D simulation.

Gustav Born

Interview
on: The Vega Science Trust
Gustav Born jokes that all his life he has been the son of a famous scientist (Max Born) and then later he became uncle to a famous film star (Olivia Newton John), he is also directly related to Martin Luther, Ben Elton and numerous other notable people but this programme is dedicated to Gustav Born's life and work as a Pathophysiologist. Here Gustav talks about his experience as medical student, he explains his work on platelet aggregation and the effect of aspirin, he talks about his relationship with his father, the development of lung machines, his science - past and his present, his present day family, his views on rationality and society and last but not least his love of music.

The Pleasure of Finding Things Out

Speaker: Richard Feynman
Time: 50 minutes

Fifty minutes of PURE Feynman! This is the original Horizon Nova interview - essential for any Feynman fan... and for everyone else too!
THE PLEASURE OF FINDING THINGS OUT was filmed in 1981 and will delight and inspire anyone who would like to share something of the joys of scientific discovery. Feynman is a master storyteller, and his tales -- about childhood, Los Alamos, or how he won a Nobel Prize -- are a vivid and entertaining insight into the mind of a great scientist at work and play.
'The 1981 Feynman Horizon is the best science program I have ever seen. This is not just my opinion - it is also the opinion of many of the best scientists that I know who have seen the program... It should be mandatory viewing for all students whether they be science or arts students.' - Professor Sir Harry Kroto, Nobel Prize for Chemistry
