Putting the Future Back in the Room. Putting the Future Back in the Room The future that my parents' generation warned us about forty years ago looks an awful lot like our present.
The ice caps are melting, deserts are spreading, the planet is thick with people, most of the world's primeval forests are gone, the seas are in crisis, and pollution, famine and natural disasters kill millions of people a year. Compared to the world we might have had, had the progress of the early 1970s continued steadily through the following four decades, we live on a half-ruined planet. That half-ruined planet, though, is our home. People old enough to remember the first Earth Day can well grieve for that other, healthier Earth we might have had if only older generations had made different choices. 1970 is the same distance in time away from us now as 2050: that's how close the future is. That void in our future vision, I believe, is not accidental. There is a vicious political fight for the future happening right now.
One Day on Earth - The World's Story is Yours to Tell. Why is Earth Day celebrated on April 22? The first Earth Day – April 22, 1970 – marked the beginning of the modern environmental movement.
Approximately 20 million Americans, especially on college campuses, participated in a national teach-in on environmental issues and protests against environmental deterioration on the first Earth Day. It’s hard to imagine it now, but the first Earth Day was a revelation to many, a way not only of raising consciousness about environmental issues but also of bringing together separate groups that had been fighting separately against issues including oil spills, pollutions from factories and power plants, raw sewage, toxic dumps, pesticides, the loss of wilderness, air pollution and more.

Statistical Basis for Predicting Technological Progress. Forecasting technological progress is of great interest to engineers, policy makers, and private investors.
Several models have been proposed for predicting technological improvement, but how well do these models perform? An early hypothesis made by Theodore Wright in 1936 is that cost decreases as a power law of cumulative production. An alternative hypothesis is Moore's law, which can be generalized to say that technologies improve exponentially with time. Other alternatives were proposed by Goddard, Sinclair et al., and Nordhaus. The "X-ray Eyes" of NASA's Chandra X-ray Observatory. Parsons The New School for Design. Oxford Genomics Centre - Home. Field Guide to X-ray Astronomy. Chemistry and the Universe Chemistry, the study of the intricate dances and bondings of low-energy electrons to form the molecules that make up the world we live in, may seem far removed from the thermonuclear heat in the interiors of stars and the awesome power of supernovas.
Yet, there is a fundamental connection between them. To illustrate this connection, the familiar periodic table of elements—found in virtually every chemistry class—has been adapted to show how astronomers see the chemical Universe. What leaps out of this table is that the simplest elements, hydrogen and helium, are far and away the most abundant. The Universe started out with baryonic matter in its simplest form, hydrogen. Stellar Evolution Activity. FoxP2. El gen y proteína FoxP2, descubierto en los años noventa del siglo XX, está relacionado con el lenguaje humano: su mutación se correlaciona con determinados trastornos específicos del lenguaje. Aunque se ha acuñado la expresión gen del lenguaje o del habla para caracterizarlo, se trata de un factor más entre los responsables de la competencia humana para el lenguaje.

Deformities in North American Amphibians In 1995, a group of Minnesota school children on a biology field trip were shocked by finding dozens of misshapen Northern Leopard frogs, Rana pipiens.
This highly publicized incident led to an international media frenzy! Never has a herpetological phenomenon received such wide-spread publicity with such little scientific writing (or perhaps knowledge) to back it up. Within weeks the Minnesota Pollution Control Agency and the federal Environmental Protection Agency began a statewide survey. Early results exhibited a malformation rate as high as 80% in some ponds and lakes.
The United States Geological Survey in conjunction with several researchers formed the North American Reporting Center for Amphibian Malformations (NARCAM).

Comparison to other radixes Sum of the digits in ternary as opposed to binary The value of a binary number with n bits that are all 1 is 2n − 1.
Similarly, for a number N(b,d) with base b and d digits, all of which are the maximum digit value b − 1, we can write N(b,d) = (b − 1) bd−1 + (b − 1) bd−2 + … + (b − 1) b1 + (b − 1) b0, Untitled. Alexandre Bouchard-CÃ´tÃ© General.

Para experimentar los efectos de la superconductividad es necesario enfriar la muestra a muy bajas temperaturas Demostración del efecto Meissner El efecto Meissner, también denominado efecto Meissner-Ochsenfeld, consiste en la desaparición total del flujo del campo magnético en el interior de un material superconductor por debajo de su temperatura crítica.
Fue descubierto por Walter Meissner y Robert Ochsenfeld en 1933 midiendo la distribución de flujo en el exterior de muestras de plomo y estaño enfriados por debajo de su temperatura crítica en presencia de un campo magnético. Meissner y Ochsenfeld encontraron que el campo magnético se anula completamente en el interior del material superconductor y que las líneas de campo magnético son expulsadas del interior del material, por lo que este se comporta como un material diamagnético perfecto.

Science - News for Your Neurons. RLUK. Robert N. M. Watson: Home Page @ cl.cam.ac.uk. I am a University Lecturer in Systems, Security, and Architecture in the Security Research Group at the University of Cambridge Computer Laboratory. I lead a number of cross-layer research projects spanning computer architecture, compilers, program analysis, program transformation, operating systems, networking, and security. Current projects include CTSRD, a project in collaboration with SRI International looking at clean-slate hardware and software designs for security. This includes the BERI and CHERI processor designs, and SOAAP and TESLA, software analysis and transformation systems based on LLVM. I also have active research projects in network-stack performance, tracing, and switching. Recent completed projects include the Capsicum hybrid capability system, system-call interposition concurrency problems, and the TrustedBSD MAC Framework, a widely deployed OS access-control extensibility framework (now found in FreeBSD, Mac OS X, Apple iOS, Junos, and other products).
