From The Daily Mail Online:

It can usually only be seen as a faint fuzzy spot through the average telescope, but these stunning images show just how magnificent the spiral galaxy NGC 7331 can be.

The galaxy is around 50million light years away in the northern constellation, Pegasus, and is similar in size to our own 'Milky Way' galaxy.

The long-exposure photographs were taken with a LAICA camera (Large Area Imager) by the Calar Alto Observatory, based in southern Spain, who attached a camera to a 3.5m telescope to capture the impressive shots.

The outstanding spiral structure of NGC 7331 is seen shining behind a number of stars belonging to our galaxy the Milky Way, and in front of a rich background populated by an overwhelming variety of distant galaxies.

A thin haze of the ghostly, fuzzy and dusty nebulae known as galactic cirrus is visible. The diffuse clouds are made up from dust, complex organic molecules and gas.

NGC 7331 was discovered by the astronomer Wilhelm Herschel in 1784. The sharpness of the images are believed to represent the deepest view of the region to date.

Chinese Angry Over Microsoft Anti-Piracy Tool

From MSNBC/Reuters:

Program turns computer screen black if installed software fails validation

BEIJING - Chinese Internet users have expressed fury at Microsoft's launch of an anti-piracy tool targeting Chinese computer users to ensure they buy genuine software.

The "Windows Genuine Advantage" program, which turns the user's screen black if the installed software fails a validation test, is Microsoft's latest weapon in its war on piracy in China, where the vast majority of 200 million computer users are believed to be using counterfeit software, unwittingly or not.

"Why is Microsoft automatically connected with my computer? The computer is mine!" one angry blogger wrote on popular Chinese web portal Sina.com. "Microsoft has no right to control my hardware without my agreement."

Another blogger railed over the cost of authorized versions.

"If the price of genuine software was lower than the fake one, who would buy the fake one?" he wrote.

McGill Physicists Find A New State Of Matter In A 'Transistor'

From E! Science News:

McGill University researchers have discovered a new state of matter, a quasi-three- dimensional electron crystal, in a material very much like those used in the fabrication of modern transistors. This discovery could have momentous implications for the development of new electronic devices. Currently, the number of transistors that can be inexpensively crammed onto a single computer chip increases exponentially, doubling approximately every two years, a trend known as Moore's Law. But there are limits, experts say. As chips get smaller and smaller, scientists expect that the bizarre laws and behaviours of quantum physics will take over, making ever-smaller chips impossible.

This discovery, and other similar efforts, could help the electronics industry once traditional manufacturing techniques approach these quantum limits over the next decade or so, the researchers said. Working with one of the purest semiconductor materials ever made, they discovered the quasi-three-dimensional electron crystal in a device cooled at ultra-low temperatures roughly 100 times colder than intergalactic space. The material was then exposed to the most powerful continuous magnetic fields generated on Earth. Their results were published in the October issue of the journal Nature Physics.

Space Programs Poised for Major Expansion in Asia

From National Defense Magazine:

SAPPORO, Japan — Japan’s government is about to kick off a major expansion of the nation’s space programs. The goal is to broaden the scope of space research from traditional areas such as exploration into new military and commercial applications.

The intent is to boost the country’s space industry and, over time, become less dependent on foreign suppliers such as the United States.

“There was a huge inferiority complex for the Japanese industry, that we needed to catch up with the top-level, state-of-the-art technology,” says Hokkaido University associate professor Kazuto Suzuki.

These goals would have been unrealistic until Japan’s legislature passed a law that for the first time creates a dedicated space bureau — run by a controversial politician, Seiko Noda.

“They knew they had to change their space law and their space organization because they were not structured and organized in order to compete in the 21st century,” says Vincent Sabathier, senior fellow and director of space initiatives at the Center for Strategic and International Studies in Washington.

The Japanese government beginning in the 1970s invested 4 trillion yen into research and development projects, including satellites, rockets, launchers, exploration spacecraft, and most recently, Kibo, the experimental module that was installed aboard the International Space Station this summer.

Do Five Simple Things A Day To Stay Sane, Say Scientists

From Times Online:

Simple activities such as gardening or mending a bicycle can protect mental health and help people to lead more fulfilled and productive lives, a panel of scientists has found.

A “five-a-day” programme of social and personal activities can improve mental wellbeing, much as eating fruit and vegetables enhances physical health, according to Foresight, the government think-tank. Its Mental Capital and Wellbeing report, which was compiled by more than 400 scientists, proposes a campaign modelled on the nutrition initiative, to encourage behaviour that will make people feel better about themselves.

People should try to connect with others, to be active, to take notice of their surroundings, to keep learning and to give to their neighbours and communities, the document says.

Its advice to “take notice” includes suggestions such as “catch sight of the beautiful” and “savour the moment, whether walking to work, eating lunch or talking to friends”. Examples of learning include mending a bike or trying to play a musical instrument.

From Wired Science:

When the next big earthquake hits the San Francisco Bay Area, it will be a catastrophe of Hurricane Katrina proportions. Hundreds, perhaps thousands of people will die, and hundreds of thousands will become homeless. Economic losses will be on the order of $200 billion, the vast majority of it uninsured. Outside help will be desperately needed, but difficult to coordinate and execute.

And just as before Hurricane Katrina, scientists have been sounding the alarm, warning that the disaster is inevitable. It's not a matter of if, but when the "Big One" will strike.

"The reality is that we could have a large earthquake at any time," said geologist David Schwartz of the U.S. Geological Survey.

The Bay Area is lined with faults capable of delivering a knock-out blow. But one in particular is poised to rupture sooner than later. Geologists have determined that the average time between major earthquakes on the Hayward fault is 140 years. The last big one was October 21, 140 years ago.

Invention: Hurricane Pacifier

Releasing smoke particles into the lower reaches of a hurricane can shift energy to its periphery and reduce the severity of the storm, say the authors of a new patent application (Image: WIPO)

From New Scientist Tech:

Interest in hurricane mitigation has peaked since Hurricane Katrina devastated New Orleans in 2005, and any means of limiting the damage wrought by these huge storms would be welcomed by governments and vulnerable populations alike.

Now an Israeli team says it has developed a way to take the sting out of the storms. Their new patent application says seeding hurricanes with smoke particles could lower wind speeds enough to mitigate their destructive potential.

A hurricane's destructive potential is proportionally related to the strongest winds inside it, and only a small reduction in wind speed is needed to dramatically reduce the damage it causes.

Hurricanes derive their immense power from warm waters on the surface of the sea. As the water evaporates, it rises into the hurricane and eventually condenses and falls as rain, releasing its latent heat energy as it does so – a process known as "heat cycling".

Daniel Rosenfeld and colleagues at the Hebrew University of Jerusalem say injecting smoke into the lower parts of a hurricane causes water vapour to condense at a lower altitude than usual, and form droplets that are too small to fall as rain.

Sizing Up The Earth

"Earth" is the largest atlas ever produced and weighs over 30 kilos. (Image from CNN)

From CNN:


LONDON, England (CNN) -- It is being billed as the ultimate book about the world and it is something of a landmark in its own right. "Earth" -- the biggest atlas ever to be published -- promises to be a luxurious benchmark in cartography.

Created by Millennium House, "Earth" -- complete with a clam shell case -- measures 610 x 469 millimeters and weighs in at over 30 kilos.

The price is pretty hefty too. The leather bound, gilt-edged book will set you back around $3500.

Its existence owns much, if not all, to the perseverance of Australian businessman Gordon Cheers who has been dreaming of creating such a book for over 20 years.

Cheers, who has spent much of his working life at some of the world's major publishing houses, couldn't convince his various employers to take the project on. Penguin said no. So did Random House.

Undeterred, Cheers decided to start his own company, Millennium House, which produces a wide range of high quality reference books.

Less Ice In Arctic Ocean 6000-7000 Years Ago
-- Science Daily


ScienceDaily (Oct. 20, 2008) — Recent mapping of a number of raised beach ridges on the north coast of Greenland suggests that the ice cover in the Arctic Ocean was greatly reduced some 6000-7000 years ago. The Arctic Ocean may have been periodically ice free.

”The climate in the northern regions has never been milder since the last Ice Age than it was about 6000-7000 years ago. We still don’t know whether the Arctic Ocean was completely ice free, but there was more open water in the area north of Greenland than there is today,” says Astrid LysÃ¥, a geologist and researcher at the Geological Survey of Norway (NGU).

Form Cosmic Log/MSNBC:

The current round of financial uncertainty is coming at just the wrong time for America's largest and smallest fusion research programs.

In its simplest form, nuclear fusion involves combining the nuclei of hydrogen atoms to produce helium atoms, plus a smidgen of energy. It's the energy reaction that powers the sun as well as hydrogen bombs. For decades, scientists have been trying to tame the process to produce what could be an abundant, high-yield power source that is less environmentally problematic than nuclear fission.

Federal funding currently backs three strategies for fusion power:

Lethal Build-Up Of Ozone Poses Threat To UK

From The Guardian:

Scientists call for global measures amid warnings that the gas damages health and the environment

Britain is ignoring the dangers posed by one of the world's worst air pollutants: ozone. Researchers say that levels of the gas - a powerful contributor to global warming and the cause of hundreds of deaths a year from respiratory illnesses - are rising at an alarming rate.

They have also warned that measures to curtail the gas are failing. As a result, ozone-related deaths, of which there are about 1,500 a year in the UK, could rise by 50 per cent over the next decade. Stronger international treaties need to be set up to counter the threat, they insist.

'A lot more interest needs to be taken in ozone - not only as a cause of global warming but as an immediate threat to human health and to the environment,' said Professor Piers Foster of Leeds University, an author of the most recent report from the Intergovernmental Panel on Climate Change. 'It could have a significant impact on the planet.'

Offshore Wind May Power the Future

From Scientific American:

The waters of the Jersey Shore may soon become home to the nation's first deepwater wind turbines. New Jersey officials recently announced the state would help fund an initiative by Garden State Offshore Energy to build a 350-megawatt wind farm 16 miles (26 kilometers) offshore. The state wants by 2020 many more of these parks, at least 3,000 megawatts worth, or about 13 percent of the state's total electricity needs.

"This is probably the first of many ambitious goals to be set by states," says Greg Watson, a senior advisor on clean energy technology to the governor of Massachusetts. "Three thousand megawatts is significant. With that you're able to offset or even prevent fossil fuel plants from being built."

The federal government is about to open up to wind energy development vast swaths of deep ocean waters, and states and wind park developers are vying to be the first to seize the new frontier. Wind parks in these waters can generate more energy than nearshore and onshore sites, they don't ruin seascape views, and they don't interfere as much with other ocean activities.

'Western' Diet Increases Heart Attack Risk Globally

From E! Science News:

The typical Western diet — fried foods, salty snacks and meat — accounts for about 30 percent of heart attack risk across the world, according to a study of dietary patterns in 52 countries reported in Circulation: Journal of the American Heart Association. Researchers identified three dietary patterns in the world:

* Oriental: higher intake of tofu, soy and other sauces;
* Prudent: higher intake of fruits and vegetables; and
* Western: higher intake of fried foods, salty snacks, eggs and meat.

The Prudent diet was associated with a lower heart attack risk than the Oriental, researchers said.

"The objective of this study was to understand the modifiable risk factors of heart attacks at a global level," said Salim Yusuf, D.Phil., the study's senior author.

Previous studies have reached similar conclusions about the Prudent and Western diet in the United States and Europe. This study broadens those findings and identifies a unique dietary pattern that researchers labeled "Oriental" (because of a higher content of food items typical of an Oriental diet.) The dietary pattern recommended by the American Heart Association is similar to the Prudent diet described in this study.

Current Mass Extinction Spurs Major Study Of Which Plants To Save

From E! Science News:

The Earth is in the midst of the sixth mass extinction of both plants and animals, with nearly 50 percent of all species disappearing, scientists say. Because of the current crisis, biologists at UC Santa Barbara are working day and night to determine which species must be saved. Their international study of grassland ecosystems, with flowering plants, is published this week in the Proceedings of the National Academy of Sciences.

"The current extinction event is due to human activity, paving the planet, creating pollution, many of the things that we are doing today," said co-author Bradley J. Cardinale, assistant professor of ecology, evolution and marine biology (EEMB) at UC Santa Barbara. "The Earth might well lose half of its species in our lifetime. We want to know which ones deserve the highest priority for conservation."

He explained that the last mass extinction near the current level was 65 million years ago, called the Cretaceous Tertiary extinction event, and was probably the result of a meteor hitting the Earth. It is best known for the extinction of non-avian dinosaurs, but massive amounts of plant species became extinct at that time as well.

'Junk' DNA May Have Important Role In Gene Regulation

From Science Daily:

ScienceDaily (Oct. 20, 2008) — For about 15 years, scientists have known that certain "junk" DNA -- repetitive DNA segments previously thought to have no function -- could evolve into exons, which are the building blocks for protein-coding genes in higher organisms like animals and plants. Now, a University of Iowa study has found evidence that a significant number of exons created from junk DNA seem to play a role in gene regulation.

The findings, which increase understanding of how humans differ from other animals, including non-human primates, appear Oct. 17 in the open-access journal PLoS Genetics.

Nearly half of human DNA consists of repetitive DNA, including transposons, which can "transpose" or move around to different positions within the genome. A type of transposon called retrotransposons are transcribed into RNA and then reintegrated into the genomic DNA. The most common form of retrotransposons in the human genome are Alu elements, which have more than one million copies and occupy approximately 10 percent of the human genome.

Thirsty World: Desperate Quest For Water -- CNN

The following is an excerpt from "What Matters," the latest book by "Day in the Life" series creator David Elliot Cohen. For more information, see whatmattersonline.com

Water is the key to life. It is fundamental to all human activities. Water grows the food we eat, generates the energy that supports our modern economies and maintains the ecological services on which we all depend. Yet billions of people worldwide still lack access to the most basic human right: safe, clean, adequate water.

As you would expect, the vast majority of these people are among the poorest in the world, living in sub-Saharan Africa and southern Asia.

Brent Stirton's images tell many stories if you know how to read them -- from the tragedy brought by lack of safe water or too much water, to the joy and life-changing effects that a new water system can offer.

Africa Needs Disease Warning Systems

From Cosmos Magazine:

BARCELONA: Africa needs early warning systems to deal with the increased threat of disease spreading from wild animals to humans caused by climate change, health experts say.

Speaking at the International Union for Conservation of Nature congress in Barcelona, Spain, the scientists said that many wildlife pathogens, such as Ebola, may spread as a result of changing temperatures and precipitation caused by climate change

Monitoring patterns

"Building warning systems and undertaking disease surveillance in places like the Congo Basin would be cheaper than building expensive machines to control an outbreak," said William Karesh, head of the Field Veterinary Program at the Wildlife Conservation Society (WCS).

The early warning systems he suggested include monitoring disease patterns in wild animals, and monitoring environmental changes and how these affect the behaviour of wild animals and pathogens.

According to Karesh, these offer both fertile ground for building early warning systems and areas for future research. "Wild animals are more susceptible to new diseases than domesticated animals, and are good indicators of an impending outbreak," he said.

Hi-Tech Brings Families Together

From the BBC:

Technology is helping families stay in touch like never before, says a report.

Instead of driving people apart, mobile phones and the net are helping them maintain social ties, says the Pew Internet report.

Families are also among the keenest users of technology, the survey of 2,252 Americans revealed.

It found that using the net was often a social activity within families, with 51% of parents saying they browsed the web with their children.

"Some analysts have worried that new technologies hurt family togetherness, but we see that technology allows for new kinds of connectedness built around cell phones and the internet," said Tracy Kennedy of the University of Toronto who helped to write the Networked Families report.
