Science Untarnished By 'Climategate,' U.N. Says
From CNET News:LONDON--The head of the U.N.'s panel of climate experts rejected accusations of bias on Thursday, saying a "Climategate" row in no way undermined evidence that humans are to blame for global warming.
Climate change skeptics have seized on a series of e-mails written by specialists in the field, accusing them of colluding to suppress data which might have undermined their arguments.
The e-mails, some written as long as 13 years ago, were stolen from a British university by unknown hackers and spread rapidly across the Internet.

Is Cataract Surgery Scary?
From Live Science:
This Week’s Question: I have to have cataract surgery and I’m a little frightened. Should I be?
I don’t know anyone who isn’t a little frightened by surgery of any kind, but cataract removal is one of the safest and most effective types of surgery. It’s also one of the most common operations performed in the United States. About 9 out of 10 people who have the surgery have improved vision.
A cataract is a clouding of the lens, the clear part of the eye that helps focus images like the lens in a camera. Cataracts can blur images and discolor them.

FUTURE HUMANS: Four Ways We May, Or May Not, Evolve
Looking backward, evolutionary theory—popularized by Charles Darwin's On the Origin of Species, published in 1859—has traced humanity's roots to fossil apes. Now, 150 years later, scientists are looking forward and seeing a range of evolutionary futures for humans. Will our descendants be muscle-bound cyborgs? Electronic immortals? Or is human evolution dead? Photograph by Rebecca Hale, NGSFrom National Geographic:
But where is evolution taking us? Will our descendants hurtle through space as relatively unchanged as the humans on the starship Enterprise? Will they be muscle-bound cyborgs? Or will they chose to digitize their consciousnesses—becoming electronic immortals?
And as odd as the possibilities may seem, it's worth remembering that, 150 years ago, the ape-to-human scenario in On the Origin of Species struck many as nothing so much as monkey business.

Solar Power Costs 50% Lower Than Last Year
From Scientific American:
New research by leading alternative energy research firm New Energy Finance finds that solar power will cost less by about 50% at the end of 2009 compared to the end of 2008.
The costs are pre-subsidy, so they could be much lower if you take better government subsidies into account.
But it isn’t only solar that’s down in cost. It’s other renewable energy sources, too.
The research company found that equipment costs (in solar, wind, and other sectors) decreased throughout the year but these were offset by increasing financing costs. However, equipment prices are expected to continue falling whereas the financing market is expected to get better.

Pacific Northwest Earthquakes Could Strike Closer To Home
From Wired Science:
Major earthquakes occurring along the Cascadia subduction zone off the coast of Washington state could strike closer to the state’s urban areas than some models have suggested, a new study notes.
GPS data gathered at dozens of sites throughout western Washington hint that slippage along the interface between the North American and Juan de Fuca tectonic plates could occur as deep as 25 kilometers below the Earth’s surface, says Timothy I. Melbourne, a geodesist at Central Washington University in Ellensburg. That depth, in turn, would place the epicenters of quakes triggered along that portion of the subduction zone — some of which could exceed magnitude 9 —more than 60 kilometers inland, he and CWU colleague James Chapman report online and in the November 28 Geophysical Research Letters.

If planet Earth becomes too crowded, where else in the solar system could humankind live? Space expert Steven Cutts considers our options.
For decades, the most popular destination for migrants the world over has been the United States. It was in America that the downtrodden and the footloose of this world saw their destiny. But America's ability to accommodate such people has always been finite. Billions of poverty-stricken people today crave the comfort and the affluence of a better world and almost none of them can have it. The increase in global population now exceeds the entire population of the US every five years; if migration is the solution to the problems of mankind then we're going to have to find a different planet.

2011 Ferrari 458 Italia Supercar Test Drive
From Popular Mechanics:
MARANELLO, Italy—Ferarri's new lust-worthy 562-hp supercar hits 60 mph in 3.4 seconds. It's indisputably attractive, but it is also derivative, as though it had been concocted from the best parts of previous great Ferrari designs. Let's see what it can do on real roads.
The Specs:
Ferrari's early cars were dominated by V12 engines. But the Italian sports car maker inherited its first V8 from Lancia in 1955, and its mid-engined V8 sport coupes have been the backbone of the company's model range for the last 35 years. Strictly speaking, the first road-going production-V8 Ferrari was the wedge-shaped, Bertone-designed Dino GT4 of 1973. The most recognizable was of course the Pininfarina-designed 308 launched at the 1975 Paris Motor Salon—a car that starred quite prominently in the hit TV series Magnum PI.

Science Daily (Nov. 26, 2009) — Are ladybugs being overtaken by wasps? A Université de Montréal entomologist is investigating a type of wasp (Dinocampus coccinellae) present in Quebec that forces ladybugs (Coccinella maculata) to carry their larvae. These wasps lay their eggs on the ladybug's body, a common practice in the insect world, yet they don't kill their host.

PARIS: Slowing population growth would help battle global warming, says an unprecedented U.N. report that links demographic pressure and climate change.
"Slower population growth... would help build social resilience to climate change's impacts and would contribute to a reduction of greenhouse-gas emissions in the future," the U.N. Population Fund (UNFPA) says.
Its 104-page document emphasises that population policies be driven by support for women, access to family planning, reproductive health and other voluntary measures.
