Alien Giant Snakes Threaten To Invade Up To 1/3 of U.S.

Researchers place a radio transmitter inside a 16-foot (5-meter) Burmese python in Florida's Everglades National Park in an undated photo. Native to Asia, the species is already established in the wild in Florida and is taking a toll on Floridian animals. A similar fate could await ecosystems in a wide swath of the U.S. if other non-native giant snake species are allowed to flourish in the country, an October 2009 study says.

From National Geographic:

Nine species of giant snakes—none of them native to North America and all popular pets among reptile lovers—could wreak havoc on U.S. ecosystems if the snakes become established in the wild, according to a new study by the U.S. Geological Survey (USGS) .

Two of the giant snakes are already at home in Florida. One of them, the Burmese python, has the potential to infiltrate the entire lower third of the U.S., the study says.

The Other Peak Oil: Demand From Developed World Falling

OIL HALT: Demand for oil in developed countries could be passed its prime.
WIKIMEDIA COMMONS/FLCELLOGUY

From Scientific American:

Oil demand in industrialized countries peaked in 2005 and will not reach that high again, a new report predicts.

Demand for oil in developed nations peaked in 2005, and changing demographics and improved motor-vehicle efficiency guarantee that it won't hit those heights again, IHS Cambridge Energy Research Associates says in a new report.

Reduced petroleum demand in developed nations could make their economic growth less vulnerable to oil price shocks, the report states.

Natural Gas Changes the Energy Map

Deep drilling: At Range Resources’ site in Washington County, PA, a specially designed rig is used to drill more than a thousand meters down and gradually turn 90° to follow the gas-rich shale deposit. The rig will drill half a dozen wells at the site. Beside it is a pond holding debris and mud from a well. Credit: Roy Ritchie

From Technology Review:

Vast amounts of the clean-burning fossil fuel have been discovered in shale deposits, setting off a gas rush. But how it will affect our energy use is still uncertain.

The first sign that there's something unusual about the flat black rocks strewn across the shore of Lake Erie comes when Gary Lash smashes two of them together. They break easily and fall into shards that give off the faint odor of hydrocarbons, similar to the smell of kerosene. But for Lash, a geologist and professor at nearby SUNY Fredonia, smashing the rocks is a simple trick designed to catch the attention of a visitor. The black outcroppings that protrude from the nearby bluff onto the narrow beach are what really interest him.

Time-Travelling Higgs Sabotages The LHC. No, Really

From New Scientist:

Could the Large Hadron Collider be sabotaging itself from the future? That's the suggestion of a couple of reasonably distinguished theoretical physicists, which has received a fresh airing in the New York Times today.

Actually, it's the Higgs boson that is doing the sabotage. Apparently, among the many singular properties of the Higgs that the LHC is meant to discover could be the ability to turn back time to stop its cover being blown.

Or as the New York Times puts it:

"the hypothesized Higgs boson... might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather."

The Link Between Parkinson Disease And Farming

From Live Science:

Although genetics is very important in Parkinson disease (PD), many researchers believe that environmental exposures also increase a person's risk of developing the disease. There are studies that show that farmers and other agricultural workers have an increased risk of getting PD.

PD was first described in 1817 by Dr. James Parkinson, a British physician. It affects 1 in 100 people over the age of 60. It can also affect younger people. The average age of onset is 60. Research suggests that PD affects at least 500,000 people in the United States.

Gallery: Let the X-Planes Begin


From Autopia:

Few aircraft are as storied as the experimental series known as the X-Planes. These flying laboratories date to the mid-1940s and took us ever higher, further and faster.

The first, the Bell X-1, was developed to explore transonic flight after fighter pilots began experiencing control problems as they approached the speed of sound in dives. Since then, a long list of X-Planes — and other test aircraft lacking the official ‘X’ moniker — have explored the unknown edge of aerodynamics and aviation. From the early days of supersonic flight and speed records to the possibilities of unmanned combat aircraft, X-Planes have, as their pilots say, pushed the edge of the envelope.

Marine Plant Life Holds The Secret To Preventing Global Warming

Mangrove forests, salt marshes and seagrass beds, above, cover less than 1 per cent of the world's seabed, but lock away well over half of all carbon to be buried in the ocean floor

From Times Online:

Life in the ocean has the potential to help to prevent global warming, according to a report published today.

Marine plant life sucks 2 billion tonnes of carbon dioxide from the atmosphere every year, but most of the plankton responsible never reaches the seabed to become a permanent carbon store.

Mangrove forests, salt marshes and seagrass beds are a different matter. Although together they cover less than 1 per cent of the world’s seabed, they lock away well over half of all carbon to be buried in the ocean floor. They are estimated to store 1,650 million tonnes of carbon dioxide every year — nearly half of global transport emissions — making them one of the most intense carbon sinks on Earth.

Bizarre Galaxy Is Result Of Pair Of Spiral Galaxies Smashing Together

Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. NGC 2623 is in the late stages of the merging process, with the centres of the original galaxy pair now merged into one nucleus, but stretching out from the centre are two tidal tails of young stars, a strong indicator that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. (Credit: NASA, ESA and A. Evans (Stony Brook University, New York & National Radio Astronomy Observatory, Charlottesville, USA))

From Science Daily:

Science Daily (Oct. 14, 2009) — A recent NASA/ESA Hubble Space Telescope image captures what appears to be one very bright and bizarre galaxy, but is actually the result of a pair of spiral galaxies that resemble our own Milky Way smashing together at breakneck speeds. The product of this dramatic collision, called NGC 2623, or Arp 243, is about 250 million light-years away in the constellation of Cancer (the Crab).

Runny nose, persistent chill, fever, fatigue — these symptoms are all familiar evidence of influenza. But what about a heart attack, suffered 60 years later?

Researchers suggest that such distant health problems may be linked to early exposure to the flu — as early as in the womb — according to a new study that analyzed federal survey data collected from 1982 to 1996. Researchers found, for instance, that people who were born in the U.S. just after the 1918 flu pandemic (that is, people who were still in utero when the disease was at its peak) had a higher risk of a heart attack in their adulthood than those born before or long after the pandemic.

From Technology Review:

As new influenza strains emerge, researchers struggle to speed vaccine development.

Making a vaccine against seasonal influenza is a constant catch-up game. Scientists must predict which of the constantly mutating virus strains will be most virulent six months in the future, the amount of time it takes to manufacture the vaccine. The system has worked well enough for the regular flu. But when new, virulent strains emerge--including the current, rapidly spreading swine flu (H1N1)--the traditional approach falls short. Even as consumers clamored for a vaccine, it took seven months and around 48,000 confirmed U.S. cases before the first H1N1 vaccines were shipped to hospitals around the country.
