Farmers Milk Facebook, Twitter For All It's Worth

From McClatchy News:

With a hand-held video camera, a computer and 800 cows, Barbara Martin of Lemoore is letting the world into her life as a dairy operator.

No, it's not a new reality television show. And Martin isn't craving her 15 minutes of fame.

But she is joining a growing number of farmers and others in agriculture who are using social media tools to communicate with each other, send out information and educate the public about agriculture.

Brain Food: Can Maths Really Let You See Into The Future?

From The Guardian:

Meet the professor who can seemingly predict political events using a laptop.

Let's start with some news from the near future. Iran won't build a nuclear bomb. With extra aid money, Pakistan will become more peaceful. And the Copenhagen summit on climate change this December is doomed to failure.

If Bruce Bueno de Mesquita is right, those are the headlines you'll be reading over the next few months. The author of a new book called Predictioneer, he makes big-picture forecasts employing maths, and a laptop that has been so heavily used its letters have worn away.

Introducing The Most Efficient Solar Power In The World

Image: Randy Montoya

From Discovery Magazine:

It's taken 25 years, but a new solar-thermal plant in New Mexico has finally broken the old efficiency record.

In 1986 solar panels were literally ripped from the White House roof. But political will and financial incentives have reignited the search for efficient, affordable ways to harness the sun’s energy. Two new solar thermal technologies—which focus sunlight to create heat rather than convert it directly to electricity, as photovoltaics do—promise to make solar power practical at vastly different scales.

The Fusion Illusion -- A Commentary

From The New Atlantis:

To hear President Barack Obama tell it, we need to fundamentally overhaul the way we produce, deliver, and consume energy. After the House of Representatives passed the Waxman-Markey cap-and-trade bill in June, the president said it would “spark a clean energy transformation in our economy. It will spur the development of low carbon sources of energy—everything from wind, solar, and geothermal power to safer nuclear energy and cleaner coal. It will spur new energy savings, like the efficient windows and other materials that reduce heating costs in the winter and cooling costs in the summer. And most importantly, it will make possible the creation of millions of new jobs.” He repeated those sentiments before the G-8 in Italy several weeks later when he stated, “One of my highest priorities as president is to drive a clean energy transformation of our economy.”

Robots That Eat Bugs and Plants For Power

Crunch'n'Munch EATR will grab plants with its robotic arm, chop them with a mini chainsaw, and burn them in its onboard steam combustion engine to make power. Francis Govers III

From Popular Science:

Controversial robots devour biomass to gain energy independence.

No matter how intelligent a robot might be, it’s nice knowing you can pull its plug to halt the anti-human insurrection. Whoops, not anymore. A new cohort of ’bots that make energy by gobbling organic matter could be the beginning of truly autonomous machines.

Energy Crisis Is Postponed As New Gas Rescues The World

Oil shale is rock containing deposits of oil and is pictured here burning.

From The L.A. Times

Engineers have performed their magic once again. The world is not going to run short of energy as soon as feared.


America is not going to bleed its wealth importing fuel. Russia's grip on Europe's gas will weaken. Improvident Britain may avoid paralysing blackouts by mid-decade after all.

The World Gas Conference in Buenos Aires last week was one of those events that shatter assumptions. Advances in technology for extracting gas from shale and methane beds have quickened dramatically, altering the global balance of energy faster than almost anybody expected.

Wide Angle: Genetic Science

From Discovery Magazine:

Discovery Tech explores manipulating genes for our own good.

Not only has the human genome been sequenced, but so too have the genomes of many animals and crops. The sequences represent a genetic blue print of how these organisms function and how they might be repaired when they don't function. In this Wide Angle on Genetic Science, we'll look at the myriad ways, whys and hows researchers are modifying the genes of various life-forms in order to treat disease, modify crops, clone animals and repair tissue.

Blood Counts Are Clues To Human Disease

From Science Daily:

Science Daily (Oct. 12, 2009) — A new genome-wide association study published October 11 in Nature Genetics begins to uncover the basis of genetic variations in eight blood measurements and the impact those variants can have on common human diseases. Blood measurements, including the number and volume of cells in the blood, are routinely used to diagnose a wide range of disorders, including anaemia, infection and blood cell cancers.

How Loud Is Your iPod?

Some college students listen to their iPods at volumes that may lead to hearing damage, according to a new study Credit: stockxpert

From Live Science:

A teenager equipped with an iPod and earbuds can have his own personal concert — as loud and as long as he likes. But his parents might wonder if the child is listening at levels that could damage his hearing. It's possible, according to a new study of college-aged students.

In the study of 31 college students, more than half of the participants listened to their portable music players at levels that could, over a prolonged period of time, lead to hearing loss, say researchers from the University of Southern Mississippi.

Computer Program Proves Shakespeare Didn't Work Alone, Researchers Claim

From Times Online:

The 400-year-old mystery of whether William Shakespeare was the author of an unattributed play about Edward III may have been solved by a computer program designed to detect plagiarism.

Sir Brian Vickers, an authority on Shakespeare at the Institute of English Studies at the University of London, believes that a comparison of phrases used in The Reign of King Edward III with Shakespeare’s early works proves conclusively that the Bard wrote the play in collaboration with Thomas Kyd, one of the most popular playwrights of his day.

The professor used software called Pl@giarism, developed by the University of Maastricht to detect cheating students, to compare language used in Edward III — published anonymously in 1596, when Shakespeare was 32 — with other plays of the period.

A Cure For Jet Lag? Scientists Identify Brain Cell Which Keeps Us Awake

Photo: The discovery of the brain cell which determines our sleep patterns could pave the way for the introduction of a pill to beat jetlag

From The Telegraph:

A pill that cures jet lag is a step closer today, after scientists discovered how signals from the brain control our biological clocks.

Tests on mice suggested the human body clock - controlled by a region of the brain called the suprachiasmatic nuclei - does not constantly fire electrical pulses to regulate our sleeping patterns, as was previously thought.

Instead, it fires at dusk and remains inactive during the night, then stirring back to life at daybreak.

Learning To Juggle Grows Brain Networks For Good

Good for the brain (Image: Alex Segre/Rex Features)

From New Scientist:

Juggling boosts the connections between different parts of the brain by tweaking the architecture of the brain's "white matter" – a finding that could lead to new therapies for people with brain injuries.

White matter describes all areas of the brain that contain mostly axons – outgrowths of nerve cells that connect different cells. It might be expected that learning a new, complex task such as juggling should strengthen these connections, but previous work looking for changes in the brains of people who had learned how to juggle had only studied increases in grey matter, which contains the nerve cells' bodies.

Training To Climb An Everest Of Digital Data

From CNET:

MOUNTAIN VIEW, Calif.--It is a rare criticism of elite American university students that they do not think big enough. But that is exactly the complaint from some of the largest technology companies and the federal government.

At the heart of this criticism is data. Researchers and workers in fields as diverse as bio-technology, astronomy and computer science will soon find themselves overwhelmed with information. Better telescopes and genome sequencers are as much to blame for this data glut as are faster computers and bigger hard drives.
