Fraud, Errors And Misconceptions In Medical Research
Three years after being charged for fraud, misusing state funds and violating bioethics laws, disgraced South Korean stem cell researcher Hwang Woo-suk was convicted today on fraud charges, according to Reuters (The Washington Post said he was cleared of fraud but convicted on other charges).
Whichever, the court determined he has repented and so handed down a 2-year suspended sentence, according to media reports.

Ten Years After Napster, Music Industry Still Faces the (Free) Music
A full decade after Napster taught the world to share, the music industry’s resistance to new business models continues to obstruct some of the very services that could preserve it, albeit in a smaller, more efficient form.
The future of music over the next ten years depends on finding the right mix between “free” and “paid,” luring fans away from file sharing networks by offering them services that are faster, easier, and more convenient without asking them to subsidize the industry’s return to CD era profits.

Does Economics Violate The Laws Of Physics?
From Scientific American:
SYRACUSE, N.Y. -- The financial crisis and subsequent global recession have led to much soul-searching among economists, the vast majority of whom never saw it coming. But were their assumptions and models wrong only because of minor errors or because today's dominant economic thinking violates the laws of physics?

Comets Didn't Wipe Out Sabertooths, Early Americans?
From National Geographic:
A comet impact didn't set off a 1,300-year cold snap that wiped out most life in North America about 12,900 years ago, scientists say.
Though no one disputes the frigid period, more and more researchers have been unable to confirm a 2007 finding that says a collision triggered the change, known as the Younger Dryas.

Who Killed All Those Honeybees? We Did
From Discovery:
The great bee die-off is not such a mystery after all: Industrial agriculture has stressed our pollinators to the breaking point.
It was mid-July, and Sam Comfort was teetering at the top of a 20-foot ladder, desperately trying to extract a cluster of furious honeybees from a squirrel house in rural Dutchess County, New York. Four stingers had already landed on his face, leaving welts along the fringe of his thick brown beard. That morning, the owner of the squirrel house had read an article in the local paper about Comfort’s interest in collecting feral honeybees, so he called and invited him over. Commercial bee colonies, faced with massive mortality rates, are not faring so well these days, and unmanaged hives like this one could be their salvation. Comfort hurried over, eager to capture the hive’s queen and bring her home for monitoring and, if she fares well, breeding.

For the First Time, Geneticists Diagnose Disease Through Whole-Genome Analysis
From Popular Science:
For the first time, researchers have made a clinical diagnosis by sequencing the entire protein-coding parts of a person's genome.
"We have shown that one can use whole genome sequencing to make clinically meaningful diagnoses- it is technically feasible . . . and can provide new clinical insight that directs treatment," Richard Lifton, a geneticist at Yale who spearheaded the research, told Popsci.com.

How Galileo And His Spyglass Turned The World On Its Head
From The Telegraph:
Today it would hardly pass muster as a child's plaything, but the telescope Galileo used 400 years ago this week to peer into the heavens overturned the foundations of knowledge, changing our perception of the universe and our place in it.
Galileo's "optick tube" had a meagre 9x magnification and was not even conceived for astronomy.
Indeed, when the gadget was first demonstrated, Venetian senators were so smitten with its military potential that they doubled Galileo's salary and awarded him a life tenure in the city-state's most prestigious university.

Time-Keeping Brain Neurons Discovered
From Science Daily:
Science Daily (Oct. 23, 2009) — Keeping track of time is one of the brain's most important tasks. As the brain processes the flood of sights and sounds it encounters, it must also remember when each event occurred. But how does that happen? How does your brain recall that you brushed your teeth before you took a shower, and not the other way around?

Cleanliness May Foster Morality
A simple spritz of a fresh-smelling window cleaner made people more fair and generous in a new study.
The researchers figure cleanliness fosters morality.
They conducted fairness tests, with subjects completing tasks in a room that was either unscented or one that was sprayed with a common citrus-scented window cleaner.

Mum's the Word for NASA's Secret Space Plane X-37B
re-entering Earth's atmosphere. NASA
From FOX News:
You would think that an unpiloted space plane built to rocket spaceward from Florida atop an Atlas booster, circle the planet for an extended time, then land on autopilot on a California runway would be big news. But for the U.S. Air Force X-37B project — seemingly, mum's the word.
There is an air of vagueness regarding next year's Atlas Evolved Expendable launch of the unpiloted, reusable military space plane. The X-37B will be cocooned within the Atlas rocket's launch shroud — a ride that's far from cheap.

Where Will The Next Five Big Earthquakes Be?
From Time Magazine:
Earthquakes have always been part of Los Angeles' past — and its future. In 1994 a 6.7-magnitude quake hit the Northridge area of the city, badly damaging freeways, killing more than 70 people and causing $20 billion in damages. But those numbers could be dwarfed by a major quake in the future. The geologic record indicates that huge quakes occur roughly every 150 years in the region — Los Angeles lies along the southern end of the San Andreas Fault — and the last big quake, which registered a magnitude 7.9, happened in 1857. Los Angeles has done a lot to beef up its building codes and emergency response in the 15 years since the Northridge quake and may be better prepared than any other major American city, but the city's sheer size ensures the next Big One will be bloody.

From The Telegraph:
The first road atlas of its kind in western Europe, a 17th century book showing a highway network in England and Wales of just 73 roads, is to be sold at auction for up to £9,000.
The route atlas, published in 1675, includes 100 double pages of black and white maps laid out in continuous strips depicting the major roads and crossroads across England and Wales.
The work by John Ogilby – Britannia Volume the First, or an Illustration of the Kingdom of England and Dominion of Wales – also marks the first time in England that an atlas was prepared on a uniform scale, at one inch to a mile.

Carefully Cleaning Up The Garbage At Los Alamos
From The New York Times:
LOS ALAMOS, N.M. — No one knows for sure what is buried in the Manhattan Project-era dump here. At the very least, there is probably a truck down there that was contaminated in 1945 at the Trinity test site, where the world’s first nuclear explosion seared the sky and melted the desert sand 200 miles south of here during World War II.

Spencer: AGW Has Most Of The Characteristics Of An “Urban Legend”
From Watts Up With That?
About.com describes an “urban legend” as an apocryphal (of questionable authenticity), secondhand story, told as true and just plausible enough to be believed, about some horrific…series of events….it’s likely to be framed as a cautionary tale. Whether factual or not, an urban legend is meant to be believed. In lieu of evidence, however, the teller of an urban legend is apt to rely on skillful storytelling and reference to putatively trustworthy sources.
I contend that the belief in human-caused global warming as a dangerous event, either now or in the future, has most of the characteristics of an urban legend. Like other urban legends, it is based upon an element of truth. Carbon dioxide is a greenhouse gas whose concentration in the atmosphere is increasing, and since greenhouse gases warm the lower atmosphere, more CO2 can be expected, at least theoretically, to result in some level of warming.

NASA Ares Rocket Development To Take Too Long
An article in New Scientist about the NASA Ares rocket program reports that a White House advisory panel chaired by former Lockheed Martin CEO Norman Augustine recommends against further development of the Ares rocket because it will take too long to develop.
Read more ....The rocket is set to make its first test flight on 27 October. But the committee believes the rocket will not be ready to loft crew to orbit until 2017, two years after the ISS is scheduled to be abandoned and hurled into the Pacific Ocean, Augustine said. Extending use of the space station to 2020 would not make much difference, since this would eat up funds available for Ares I and delay its first flight to 2018 or 2019, added committee member Edward Crawley of MIT.
