Better To Live In Country With Rights-Possessing Robots?

Photo: Female Cylons from Battlestar Galactica

From The Future Pundit:

Robin Hanson doesn't want to live in a country where robots are held back from full sentience and autonomy.

On Tuesday I asked my law & econ undergrads what sort of future robots (AIs computers etc.) they would want, if they could have any sort they wanted. Most seemed to want weak vulnerable robots that would stay lower in status, e.g., short, stupid, short-lived, easily killed, and without independent values. When I asked “what if I chose to become a robot?”, they said I should lose all human privileges, and be treated like the other robots. I winced; seems anti-robot feelings are even stronger than anti-immigrant feelings, which bodes for a stormy robot transition.

New Dinosaur Extinction Theory Causes Debate

An artist rendering of a space rock streaking toward Earth. Most experts think an impact off the Yucatan Peninsula 65 million years ago was the primary cause of the dinosaur demise. Others think volcanism and climate change may have played a role. A new and controversial idea suggests there was another, larger impact in India that was responsible. Stockxpert

From MSNBC:

The extinction of the dinosaurs has often been traced to a giant space rock impact on the Earth 65 million years ago. But now a scientist is saying experts have blamed the wrong impact. The new thinking was met with sharp criticism from other researchers, however.

Paleontologist Sankar Chatterjee of Texas Tech University says a giant basin in India called Shiva could also be an impact crater from the time of the dinosaurs' demise, and the crash that created it may have been the cause of the mass extinction scientists call the KT (Cretaceous–Tertiary) event, which killed off more than half the Earth's species along with the dinos. This argument runs counter to the widely-held wisdom that the Chicxulub impact on the Yucatan Peninsula off Mexico was behind the cataclysm.

From Live Science:

Since Darwin’s time, biologists have tried to understand the advantages of sexual reproduction.
This is not trivial because there are clear disadvantages to sex.

Unlike sexual organisms, asexuals do not need a partner to reproduce, can reproduce clonally, and can produce twice as many female offspring. If there were no advantages to sex, and both sexual and asexual individuals were competing for resources, the asexuals would take over in only a few generations.

From Time Magazine:

The planet is in the middle of an extinction crisis, the sixth great wave in its history. But unlike major extinction events of the past — like the Permian-Triassic event 250 million years ago, in which 70% of all terrestrial species were wiped out, probably because of an asteroid impact or a similar natural disaster — this time human beings are the cause. Hard numbers are difficult to find, but many scientists believe Earth's species are going extinct at a rate that is up to 1,000 times higher than before human beings came on the scene.

See How The Earth Moves

(Click Above Image to Enlarge)
The image above shows an interferogram, a map of ground movements produced with measurements made remotely by Interferometric Synthetic Aperture Radar (InSAR), plotted atop digital topography. United Kingdom geophysicists Richard Walters and John Elliott used measurements acquired by a European Space Agency satellite on February 1 and April 12 to capture ground movements from the April 6 earthquake in central Italy. The color bands (red through blue) represent contours of ground motion toward or away from the satellite, within its line of sight. Moving towards the center of each lobe, each contour represents an additional 2.8 centimeters of ground motion. The image shows that during the earthquake, the region to the northeast of the Paganica fault moved toward the satellite by about 8 centimeters, whereas the region to the southwest moved away by about 25 centimeters. Each pixel in the interferogram represents an area of about 80 meters squared. Walters’ and Elliott’s research is funded by the United Kingdom’s Natural Environmental Research Council. The ESA data is copyrighted.

From The American Scientist:

Interferometric Synthetic Aperture Radar (InSAR) measurements, collected by satellites circling Earth, can provide big insights into major earthquakes. Richard Walters and John Elliott demonstrated this after a 6.3-magnitude quake struck central Italy in April, killing close to 300 people and severely damaging the medieval town of L’Aquila. By comparing measurements taken before and after the earthquake, the geophysicists pinpointed the responsible fault, measured changes aboveground and calculated likely shifts underground. Walters and Elliott are researchers at the University of Oxford and the United Kingdom’s National Centre for Earth Observation. In an e-mail exchange, Walters explained their studies to American Scientist associate editor Catherine Clabby.

Labs-On-A-Chip That You Can Shrink To Fit

Shrinking down to size (Image: Maggie Bartlett, NHGRI)

From New Scientist:

INTEL's latest microchip technology has created transistors 22 nanometres wide - a mere 200 times the width of a hydrogen molecule. Carving such tiny features is devilishly difficult and expensive, but in another realm of microchips altogether, something odd is happening: chips are being made on an outsized scale and then shrunk to the required size, avoiding much fiddly hassle.

The shrinking innovation is happening in the field of the "lab-on-a-chip". Such chips are typically plastic slivers scored with serried ranks of fluid-filled microchannels and recessed pools for chemical reactions to occur in; they are often replete with deposits of chemicals, cells and proteins of interest.

From Popular Science:

They're calling it "magnetricity" -- catchy, eh?

In 1931, physicist Paul Dirac hypothesized that on the quantum level, magnetic charge must exist in discrete packets, or quanta, in the same way that electric energy exists in a photon. This implies the existence of magnetic monopoles: particles that have a single magnetic charge, or polar identity -- north or south.

For 78 years, Dirac's speculation interested only hardcore theorists, because the conjecture failed to find any expression in observed phenomena. All magnets had two poles, one north and one south, inextricably attached to each other.

A World Redrawn When America Showed Up On A Map, It Was The Universe That Got Transformed

From Boston.com:

NEARLY FIVE CENTURIES ago, the Polish astronomer Nicholas Copernicus went public with one of the most important arguments ever made in the history of ideas. The earth did not sit immobile at the center of the universe, he wrote. It revolved around the sun.

It was the mother of all paradigm shifts, dismantling a model of the universe that had been dogma since antiquity. When he published his theory, in “On the Revolutions of the Heavenly Spheres” (1543), Copernicus provided a wealth of data on the movements of celestial bodies in support of his case. But what’s often overlooked is that he began his argument from the ground up, by focusing not on the heavens but the earth. In particular, he began with a geographical revelation, prompted by something he had recently come across on a new map.

Biggest Obstacle To Global Climate Deal May Be How To Pay For It

China’s president, Hu Jintao, seated at center, at a United Nations climate debate last month. Todd Heisler/The New York Times

From The New York Times:

As world leaders struggle to hash out a new global climate deal by December, they face a hurdle perhaps more formidable than getting big polluters like the United States and China to reduce greenhouse gas emissions: how to pay for the new accord.

The price tag for a new climate agreement will be a staggering $100 billion a year by 2020, many economists estimate; some put the cost at closer to $1 trillion. That money is needed to help fast-developing countries like India and Brazil convert to costly but cleaner technologies as they industrialize, as well as to assist the poorest countries in coping with the consequences of climate change, like droughts and rising seas.
