From Mercury News:

Windsurfers, fishing boats and cargo ships aren't the only traffic in San Francisco Bay. Great white sharks are there sometimes too.

In what is believed to be the first scientific confirmation of white sharks in San Francisco Bay, researchers from Stanford University, the University of California-Davis and other organizations put satellite and acoustic tags on 179 white sharks in Northern California waters between 2000 and 2008. They found that most of the sharks migrated thousands of miles every year, from California to as far away as Hawaii, and five swam underneath the Golden Gate Bridge in 2007 and 2008 and into bay waters.

Angry Faces: Facial Structure Linked To Aggressive Tendencies, Study Suggests

New research finds that a quick glance at someone's facial structure may be enough for us to predict their tendency towards aggression. (Credit: iStockphoto/Thomas Perkins)

From Science Daily:

Science Daily (Nov. 2, 2009) — Angry words and gestures are not the only way to get a sense of how temperamental a person is. According to new findings in Psychological Science, a quick glance at someone's facial structure may be enough for us to predict their tendency towards aggression.

Facial width-to-height ratio (WHR) is determined by measuring the distance between the right and left cheeks and the distance from the upper lip to the mid-brow. During childhood, boys and girls have similar facial structures, but during puberty, males develop a greater WHR than females.

Study Gives Clearer Picture Of How Land-Use Changes Affect U.S. Climate

This map shows observation minus reanalysis (OMR) trends in the continental United States from 1979-2003. The trends are associated with land use and land-use changes. Researchers from Purdue and the universities of Colorado and Maryland conducted a study that showed land use can affect surface temperatures locally and regionally. Units are in degrees Celsius per decade. (Image courtesy of Souleymane Fall) - click to enlarge

From Watts Up With That?

Researchers say regional surface temperatures can be affected by land use, suggesting that local and regional strategies, such as creating green spaces and buffer zones in and around urban areas, could be a tool in addressing climate change.

A study by researchers from Purdue University and the universities of Colorado and Maryland concluded that greener land cover contributes to cooler temperatures, and almost any other change leads to warmer temperatures.

Drink Responsibly: Which Is Better For The Planet, Beer Or Wine?

From Slate:

I'm hosting a dinner party next week, and I'll be serving both beer and wine alongside the meal. But it got me wondering: Which has the lower carbon footprint? Beer has to be kept refrigerated, which requires energy, but shipping wine in those heavy bottles can't be good for the planet, either.

It's hard to come up with a simple answer for this one, because so many factors affect the calculation: Where was your beverage made? What's it packaged in, and how did that package get to you? How was it stored at the point of sale? Accounting for all these variables can make your head spin, but the best available research suggests that parsing out the difference might not be worth the headache.

Brave New Climate reviews the work of Mark Z. Jacobson (Professor, Stanford) and Mark A. Delucchi (researcher, UC Davis) entitled “A path to sustainable energy by 2030” (p 58 – 65 Scientific American Nov 2009; they call it WWS: wind, water or sunlight).

Jacobson and Delucchi argue that, by the year 2030:
Wind, water and solar technologies can provide 100 percent of the world’s energy, eliminating all fossil fuels.

Carbon Emissions from Expected Wars Based on Militarization of Technology Similar to Energy Sources

They also state:

Nuclear power results in up to 25 times more carbon emissions than wind energy, when reactor construction and uranium refining and transport are considered.

80 Min Exercise Per Week Prevents Visceral Weight Gain

From Future Pundit:

Fat around your internal organs is thought to be a much bigger risk factor for heart disease than fat near the surface of the skin. Well, if you go on a diet, exercise, get your weight down, and then eventually go off the diet continued exercise will prevent the resulting weight gain from happening where the risk factor is greatest.

BIRMINGHAM, Ala. - A study conducted by exercise physiologists in the University of Alabama at Birmingham (UAB) Department of Human Studies finds that as little as 80 minutes a week of aerobic or resistance training helps not only to prevent weight gain, but also to inhibit a regain of harmful visceral fat one year after weight loss.

The study was published online Oct. 8 and will appear in a future print edition of the journal Obesity.

The Fourth Part Of The World: The Epic Story Of History’s Greatest Map By Toby Lester

From Times Online:

In 2003, the US Library of Congress spent $10m on a beautiful world map, created in 1507. The price was justified by a single, magical name, inscribed in capitals on a strange tract of blank space in the far west: “AMERICA”. As Toby Lester tells in this boundlessly engaging book, this map was not just the first to give America a name, it was the very first to show it as a continent, separated from Asia by a new ocean.

Advertising its purchase, Congress called the map “America’s birth certificate”; Lester rates its importance much less narrowly. It charts an astonishing shift in world-view, he argues, from the Europe-centred, God-driven world of the Middle Ages to the brave new imperial vision of the early modern age.

America's Natural Gas Revolution -- A Commentary

From Wall Street Journal:

A 'shale gale' of unconventional and abundant U.S. gas is transforming the energy market.

The biggest energy innovation of the decade is natural gas—more specifically what is called "unconventional" natural gas. Some call it a revolution.

Yet the natural gas revolution has unfolded with no great fanfare, no grand opening ceremony, no ribbon cutting. It just crept up. In 1990, unconventional gas—from shales, coal-bed methane and so-called "tight" formations—was about 10% of total U.S. production. Today it is around 40%, and growing fast, with shale gas by far the biggest part.

Researchers hope to create a better way to diagnose swine flu and other ailments.

Crude methods of detecting swine flu have so far provoked hand-wringing and no small amount of ridicule. Planeloads of travelers to China have had laser beams aimed at their foreheads, landing some under quarantine (and spurring a YouTube minifest of airport videos). This summer, Slate reported on a camp that tried to prescreen kids for flu by checking campers for fevers—and failed to detect a sick child whose physician parent brought his temperature down with Tylenol, fueling an outbreak. Meanwhile, people infected with the virus can pass it on before they develop symptoms; others never develop fever at all.

Clever Fools: Why A High IQ Doesn't Mean You're Smart

There's more to intelligence than just IQ. (Image: David C Ellis/Getty)

From New Scientist:

IS GEORGE W. BUSH stupid? It's a question that occupied a good many minds of all political persuasions during his turbulent eight-year presidency. The strict answer is no. Bush's IQ score is estimated to be above 120, which suggests an intelligence in the top 10 per cent of the population. But this, surely, does not tell the whole story. Even those sympathetic to the former president have acknowledged that as a thinker and decision-maker he is not all there. Even his loyal speechwriter David Frum called him glib, incurious and "as a result ill-informed". The political pundit and former Republican congressman Joe Scarborough accused him of lacking intellectual depth, claiming that compared with other US presidents whose intellect had been questioned, Bush junior was "in a league by himself". Bush himself has described his thinking style as "not very analytical".

How The Ancient Nazca Civilisation Sealed Its Own Fate By Cutting Down Forests C

An ancient geoglyph of a hummingbird (colibri in Spanish) on the edge to the Nazca plains was probably inscribed here as an offering for water/fertility in the fields that lie below

From The Daily Mail:

The mysterious people who etched the strange network of 'Nazca Lines' across deserts in Peru hastened their own demise by clearing forests 1,500 years ago, according to British scientists.

The Nazca people, famed for giant animal drawings most clearly visible from the air, became unable to grow enough food in nearby valleys because the lack of trees made the climate too dry.

Archaeologists examining the remains of the Nazca, who once flourished in the valleys of south coastal Peru, discovered a sequence of human-induced events which led to their 'catastrophic' collapse around 500 AD.

From Technology Review:

Transportation defines our civilization. Where we live and work, the structure of our cities, the flow of global commerce--all have been shaped by transportation technologies. But modern transportation's reliance on fossil fuels cannot be sustained. Passenger planes, trains, and automobiles were responsible for nearly four billion tons of carbon dioxide emissions in 2005--about 14 percent of the carbon dioxide emitted globally that year. If we continue to rely almost exclusively on petroleum to power these vehicles, they will be responsible for 11 billion to 18 billion tons of carbon dioxide emissions in 2050. That's because developing nations--which are home to 82 percent of the world's population and will be responsible for 98 percent of population growth in coming years--are on the verge of mass motorization. Auto ownership in the developing world is growing at a rate of 30 percent per year (see "Cleaner Vehicles by the Million").
