End Of An Era For Early Websites
A service that gave many people their first taste of building and owning a web page is set to close.
Yahoo-owned GeoCities once boasted millions of users and was the third most popular destination on the web.
The free site has since fallen out of fashion with users, who have switched to social networks.
Yahoo, which acquired the site for $3.57bn (£2.17bn) in 1999 at the height of the dotcom boom, said sites would no longer be accessible from 26th October.

LHC Reawakens, Sending Proton Beams Running At The Speed of Light
From Popular Science:
Over the weekend, Cern ran particle beams through the Large Hadron Collider for the first time since it was shut down last September. After a helium leak caused magnets to overheat, operations at the LHC were suspended for cleanup and repairs. After tests on October 23 and 25, scientists hope to have the LHC running again in full by November.

What Dangers Lurk in WWII-Era Nuclear Dumps?
From Discover Magazine:
Here’s one direct and obvious effect of the economic stimulus package passed in February: The toxic sites where scientists ushered in the nuclear age are getting cleaned up. In Los Alamos, New Mexico, a dump that contains refuse of the Manhattan Project and that was sealed up decades ago is finally being explored, thanks to $212 million from the American Recovery and Reinvestment Act.
But experts aren’t sure what they’ll find inside the dump. 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 [The New York Times]. It may also contain explosive chemicals that could have become more dangerous over the years of burial.
My Comment: Long after the war has ended, it's left overs are still affecting us.
A Few Coffees A Day Keeps Liver Disease At Bay
From Cosmos Magazine/AFP:
WASHINGTON DC: Researchers at the U.S. National Cancer Institute have found another good reason to go to the local espresso bar: several cups of coffee a day could halt the progression of liver disease.
Sufferers of chronic hepatitis C and advanced liver disease, who drank three or more cups of coffee per day, slashed their risk of the disease progressing by 53% compared to patients who drank no coffee, the study led by medical scientist Neal Freedman showed.

Controversial Study Suggests Vast Magma Pool Under Washington State
WASHINGTON -- A vast pool of molten rock in the continental crust that underlies southwestern Washington state could supply magma to three active volcanoes in the Cascade Mountains -- Mount St. Helens, Mount Rainier and Mount Adams -- according to a new study that's causing a stir among scientists.
The study, published Sunday in the magazine Nature Geoscience, concluded that the magma pool among the three mountains could be the "most widespread magma-bearing area of continental crust discovered so far."
Other scientists dismiss the existence of an underground vat of magma covering potentially hundreds of square miles as "farfetched" and "highly unlikely." Rather than magma heated to 1,300 to 1,400 degrees, some think it could be water.

Biofuel Displacing Food Crops May Have Bigger Carbon Impact Than Thought
From Science Daily:
Science Daily (Oct. 25, 2009) — A report examining the impact of a global biofuels program on greenhouse gas emissions during the 21st century has found that carbon loss stemming from the displacement of food crops and pastures for biofuels crops may be twice as much as the CO2 emissions from land dedicated to biofuels production. The study, led by Marine Biological Laboratory (MBL) senior scientist Jerry Melillo, also predicts that increased fertilizer use for biofuels production will cause nitrous oxide emissions (N2O) to become more important than carbon losses, in terms of warming potential, by the end of the century.

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.

Yahoo Mail Outages Plague Some Users
Yahoo Mail users reported some problems Monday morning, with the service inaccessible for some and spotty for others.
Techcrunch noticed a Twitter spike in reports of problems with Yahoo Mail, and another company called Downrightnow also reported problems accessing the service over the last several hours. Several CNET employees reported that they were able to access their in-boxes, but mine is unavailable. Yahoo Messenger and Yahoo's home page appeared to be working fine.
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.

S Korea Clone Scientist Convicted
From BBC:
A South Korean court has convicted the disgraced cloning scientist Hwang Woo-suk of embezzlement over his stem cell research.
He was given a two-year sentence suspended for three years.
The 56-year-old scientist's work had raised hopes of finding cures for diseases such as Alzheimer's.
But his research was declared bogus in 2005, and he was put on trial the following year for embezzlement and accepting money under false pretences.
Hwang's research made him a South Korean hero until revelations that it was false shocked the nation.

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.
