Antarctica's Hidden Plumbing Revealed

From The New Scientist:

THE first complete map of the lakes beneath Antarctica's ice sheets reveals the continent's secret water network is far more dynamic than we thought. This could be acting as a powerful lubricant beneath glaciers, contributing to sea level rise.

Unlike previous lake maps, which are confined to small regions, Ian Joughin at the University of Washington in Seattle and colleagues mapped 124 subglacial lakes across Antarctica using lasers on NASA's ICESat satellite (see map).

Scale Of Gorilla Poaching Exposed

From The BBC:

An undercover investigation has found that up to two gorillas are killed and sold as bushmeat each week in Kouilou, a region of the Republic of Congo.

The apes' body parts are then taken downriver and passed on to traders who sell them in big-city markets.

Conducted by the conservation group Endangered Species International, the investigation helps expose the extent of gorilla poaching in the country.

It fears hundreds more gorillas may be taken each year outside the region.

Information-Rich And Attention-Poor

From The Globe And Mail:

Coping with the troubling tradeoff between depth of what we know and how fast we retrieve it may require something like peripheral intellectual vision.

Twenty-eight years ago, psychologist and computer scientist Herbert Simon observed that the most fundamental consequence of the superabundance of information created by the digital revolution was a corresponding scarcity of attention. In becoming information-rich, we have become attention-poor.

Thunderstorm On Saturn Is A Record-Buster

The moons of Saturn passing in front of their parent planet.

From AFP:

PARIS — A tempest that erupted on Saturn in January has become the Solar System's longest continuously observed lightning storm, astronomers reported on Tuesday.

The storm broke out in "Storm Alley," a region 35 degrees south of the ringed giant's equator, researchers told the European Planetary Science Congress in Potsdam, near Berlin.

Thunderstorms there can be as big as 3,000 kilometers (nearly 2,000 miles) across.

New Virus From Rats Can Kill 80 Per Cent Of Human Victims

From Sydney Morning Herald:

A PREVIOUSLY unknown virus that killed four of the five people it struck in an outbreak in South Africa last year has been identified as part of a family of viruses humans can catch from rats.

The virus, named Lujo, is an arenavirus that over nine days caused rash, fever, muscle pain, diarrhoea, severe bleeding, vomiting, organ failure and death, said Nivesh Sewlall, who treated the first patient at Johannesburg's Morningside MediClinic Hospital. He reported the findings at an infectious disease conference in San Francisco yesterday.

From Science Daily:

ScienceDaily (Sep. 14, 2009) — Wine tastes different to those who are given information on the product before a wine tasting, tests where the test people received information on the wine before and after the tasting have shown.

Many a wine grower trembles at the prospect of a visit from Robert Parker, one of the most famous wine critics in the world. His “Parker Points” have a similar impact to the Roman Emperor’s thumb, deciding the success of a winery instead of life and death. The extent to which product information like Parker’s ratings influence the consumer is revealed in a study by Michael Siegrist, Professor of Consumer Behavior at the Institute for Environmental Decisions, and his post-doc Marie-Eve Cousin from ETH Zurich, which was published in the journal Appetite.

Do Brains Shrink As We Age?

From Live Science:

As we get older, our brains get smaller, or at least that's what many scientists believe. But a new study contradicts this assumption, concluding that when older brains are "healthy" there is little brain deterioration, and that only when people experience cognitive decline do their brains show significant signs of shrinking.

The results suggest that many previous studies may have overestimated how much our brains shrink as we age, possibly because they failed to exclude people who were starting to develop brain diseases, such as dementia, that would lead to brain decay, or atrophy.

Google Book Search: Why It Matters

From Times Online:

European publishers and copyright holders gathered in Brussels on Monday to submit their opinions to a European Commission hearing on the American Google Book Search settlement.

In a nutshell, the situation is this: Google has embarked on a project to digitise hundreds of thousands of out-of-print and out-of-copyright books in the United States.

Some of these works are still technically in copyright, and the Authors Guild and the Association of American Publishers took Google to court. A proposed settlement was reached last year, under which Google will essentially agree to pay royalties to anyone whose book they inadvertently put on line.

The settlement will be ratified in a Manhattan court on October 7 this year, by which time any European reservations will need to be registered.

From Technology Review:

Forecasters see no need for new coal and nuclear power plants.

China has doubled its installed wind power capacity every year for the past five, and is on pace this year to supplant the United States as the world's largest market for new installations. But researchers from Harvard University and Beijing's Tsinghua University suggest that the Chinese wind power industry has hardly begun to tap its potential. According to their meteorological and financial modeling, reported in the journal Science last week, there is enough strong wind in China to profitably satisfy all of the country's electricity demand until at least 2030.

From New Scientist:

SOMETHING is moving. Two robots sitting motionless in the dust have spotted it. One, a six-wheeled rover, radios the other perched high on a rocky slope. Should they take a photo and beam it back to mission control? Time is short, they have a list of other tasks to complete, and the juice in their batteries is running low. The robots have seconds to decide. What should they do?

Jupiter Turned Comet Into "Moon" For 12 Years

Jupiter (shown in a 2006 Hubble Space Telescope picture) captured a comet in 1949, and the "temporary moon" orbited the giant planet for 12 years before being cast aside, astronomers announced in September 2009.Image courtesy NASA via AP

From National Geographic:

Sixty years ago, Jupiter carried on a 12-year fling with an extra "moon" then casually cast it aside—and the gas giant will likely do it again within decades, scientists announced today.

In 1949 the massive planet's gravity pulled in comet 147P/Kushida-Muramatsu and held it in orbit until 1961, according to an international team led by Katsuhito Ohtsuka of the Tokyo Meteor Network.

Key Found to Muscle Loss After Age 65

From Live Science:

It’s a sad fact that muscles shrink as adults age. But new studies are starting to unravel how this happens — and what to do about it.

Past research has shown that the bodies of older people build muscle from food less efficiently than young people. Now researchers at the University of Nottingham in England have also found that a mechanism that prevents muscle breakdown works less effectively in people over the age of 65, resulting in a “double whammy” effect.

How Does the Brain Use So Much Energy? Not in Electrical Signals

From Discover Magazine:

Experiments conducted on squid brains in the early days of neuroscience created misunderstandings about the workings of the human brain that have persisted for 70 years, according to a new study. While the squid experiments did shed light on how messages are transmitted between brain cells with electrochemical signals (and led to a Nobel Prize for the experimenters), researchers are just now realizing that the results gave scientists a confused idea about the efficiency of neurons.

Cache And Carry: A Review Of The Kindle

From Scientific American:

The best answer yet to what's black and white and read all over.

I’m not your classic “early adopter” when it comes to new electronic gizardry (a word I just made up that means a combination of gizmo and wizardry, with a secondary definition of bird digestion). I’m not even what one ersatz electronics guru referred to as an “early adapter,” although I do sometimes wonder if my purpose in life has been reduced to making sure my various devices are all plugged in correctly.
