The following article has not undergone any scientific peer review, since that is not normal procedure for American Physical Society newsletters. The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007: "Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate."
By Christopher Monckton of Brenchley
Abstract
The Intergovernmental Panel on Climate Change (IPCC, 2007) concluded that anthropogenic CO2 emissions probably caused more than half of the “global warming” of the past 50 years and would cause further rapid warming. However, global mean surface temperature has not risen since 1998 and may have fallen since late 2001. The present analysis suggests that the failure of the IPCC’s models to predict this and many other climatic phenomena arises from defects in its evaluation of the three factors whose product is climate sensitivity:
Some reasons why the IPCC’s estimates may be excessive and unsafe are explained. More importantly, the conclusion is that, perhaps, there is no “climate crisis”, and that currently-fashionable efforts by governments to reduce anthropogenic CO2 emissions are pointless, may be ill-conceived, and could even be harmful.

with low cost fusion. Anyone with a little ambition and some technical expertise can build and test a demonstration "fuser" that achieves some fantastic effects without achieving actual fusion (which would require shielding from the neutrons produced). Once a demo machine is perfected one can introduce a little deuterium and achieve actual fusion (while using the proper safety procedures to contain the neutrons of course).

The lead scientist on the study – Giora Proskurowski of the School of Oceanography at the University of Washington in Seattle – says the hydrogen-rich fluids venting at the bottom of the Atlantic Ocean in the Lost City Hydrothermal Field were produced by the abiotic synthesis of hydrocarbons in the mantle of the earth.
The abiotic theory of the origin of oil directly challenges the conventional scientific theory that hydrocarbons are organic in nature, created by the deterioration of biological material deposited millions of years ago in sedimentary rock and converted to hydrocarbons under intense heat and pressure.
While organic theorists have posited that the material required to produce hydrocarbons in sedimentary rock came from dinosaurs and ancient forests, more recent argument have suggested living organisms as small as plankton may have been the origin.

Richard Branson and aircraft designer Burt Rutan unveiled two new aircrafts Wednesday in New York.
Burt Rutan took the cloak off of his new spacecraft on Wednesday.
Mr. Rutan, the creator of SpaceShipOne, the first privately financed craft to carry a human into space, traveled to New York to show detailed models of the bigger SpaceShipTwo and its carrier airplane, WhiteKnightTwo.

A loosely packed "carpet" of carbon nanotubes is the darkest material ever made, according to researchers from Rice University and Rensselaer Polytechnic Institute.
The carpet consists of nanotubes--hollow, honeycombed tubes made from carbon atoms-- standing vertically. Instead of being tightly packed together, the researchers went for a low density arrangement, complete with spaces and gaps, sort of like a box of dried spaghetti. Light striking the nanotubes as well as the gaps gets absorbed. When light gets absorbed, black (the absence of light) results. The nanotubes were also specially manufactured to have a more random arrangement of atoms, further reducing reflectivity. (Again, think of trying to look into a box of spaghetti. Not easy.)
This resulted in a material that reflects only 0.045 percent of the light that strikes it. (Put another way, 99.955 percent of the light that hits it gets absorbed.)
Conventional black paint reflects 100 times more light. The previous record holder for darkness, a nickel-phophorus alloy pitted with light-trapping craters, reflected four times as much light.

When Steve Fambro got bored building robots at a San Diego genetics company, he figured he could help keep his brain busy by building a kit airplane in his spare time. But his wife deemed the hobby too dangerous, so Fambro decided to build a car instead, one with low emissions and absurdly high mileage. Called the Aptera (Greek for "wingless"), the machine now exists as a working prototype. It has 2.5 seats, three wheels, weighs a feathery 1,500 pounds, and Fambro says his company will put the Aptera into production next October.
Specs may change between now and autumn 2008, but the current numbers look like this: 300 mpg, a price tag below $30,000, and 0-60 acceleration of 11 seconds (about a second slower than the Toyota Prius gas-electric hybrid).Labels: science
