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 MontoyaFrom 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.”

Energy Crisis Is Postponed As New Gas Rescues The World
Oil shale is rock containing deposits of oil and is pictured here burning.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.

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 jetlagFrom 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.

A Third of Dinosaur Species Never Existed?
Many fossils of young dinosaurs, including T. rex relatives (above, a computer-generated image of a young T. rex), have been misidentified as unique species, paleontologists said in October 2009. That means up to a third of all dinosaur species may have never existed, experts say. Photograph © NGC From National Geographic:
Many dinosaurs may be facing a new kind of extinction—a controversial theory suggests as many as a third of all known dinosaur species never existed in the first place.
That's because young dinosaurs didn't look like Mini-Me versions of their parents, according to new analyses by paleontologists Mark Goodwin, University of California, Berkeley, and Jack Horner, of Montana State University.
Instead, like birds and some other living animals, the juveniles went through dramatic physical changes during adulthood.

Science Daily (Oct. 12, 2009) — Physicists at Yale University have made the first definitive measurements of “persistent current,” a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an external power source.
The team used nanoscale cantilevers, an entirely novel approach, to indirectly measure the current through changes in the magnetic force it produces as it flows through the ring. “They’re essentially little floppy diving boards with the rings sitting on top,” said team leader Jack Harris, associate professor of physics and applied physics at Yale. The findings appear in the October 9 issue of Science.

Solar Power Outshining Colorado's Gas Industry
From Time Magazine:(DURANGO, Colo.) — The sun had just crested the distant ridge of the Rocky Mountains, but already it was producing enough power for the electric meter on the side of the Smiley Building to spin backward.
For the Shaw brothers, who converted the downtown arts building and community center into a miniature solar power plant two years ago, each reverse rotation subtracts from their monthly electric bill. It also means the building at that moment is producing more electricity from the sun than it needs.
"Backward is good," said John Shaw, who now runs Shaw Solar and Energy Conservation, a local solar installation company.

Montreal Underground -- A Look Back In History
The Pointe-à -Callière Museum From Archaeology Magazine:
This past August I traveled to Montreal for Archaeo (Archaeology) Month, which is celebrated throughout the province of Quebec. On my first day in Montreal, I met with Louise Pothier, project manager for the Montreal Museum of Archaeology and History. The museum, better known as Pointe-à -Callière and affectionately referred to as the PAC Musée, is located in Old Montreal on the very spot of the city's birthplace on May 17, 1642, and opened exactly 350 years later on May 17, 1992.
PAC Musée is situated on a point of land where the Little Saint Pierre River once ran into the St. Lawrence River. Chevalier Louis Hector de Callière, the third governor of Montreal, built a home on the site in 1688. The museum is situated atop remains of the first French settlement here, Fort Ville Marie (1642-1674), and its permanent exhibition is titled, "Where Montreal was Born."

Birth Rates Rise in Wealthiest Nations
From Live Science:
For decades, demographers have reported that the more developed a country is in terms of wealth, health, and living standards, the lower its citizens' fertility rate — so much so that most rich European and North American nations cannot sustain their populations without immigration. (The United States is a notable exception.) Eco-activists tend to welcome such news, foreseeing an end to overpopulation. But many economists and sociologists worry, because low fertility rates entail population aging, which often brings on socio-economic problems.

From Discover Magazine:
Tiny drug-carrying balls of sugar are delivering medicine in novel—and very useful—ways.
Over a thousand years ago, Mesopotamian artisans stumbled on a new way to add a special sheen to their ceramics: using microscopic pieces of metal. This "luster" was the first known use of nanoparticles—tiny objects that are less than 100 nanometers long in all three dimensions. In modern times, nanoparticles have emerged as a useful tool in medicine, with uses from providing the active ingredient in sunscreen (nano-scale particles of titanium dioxide), to stimulating blood vessel growth as an aid to healing, to delivering the key ingredients in artificial hearts (nanocrystalline zirconium oxide) and brain imaging (magnetic nanoparticles).

Timing the Singularity
From The Futurist:
The Singularity. The event when the rate of technological change becomes human-surpassing, just as the advent of human civilization a few millenia ago surpassed the comprehension of non-human creatures. So when will this event happen?
There is a great deal of speculation on the 'what' of the Singularity, whether it will create a utopia for humans, cause the extinction of humans, or some outcome in between. Versions of optimism (Star Trek) and pessimism (The Matrix, Terminator) all become fashionable at some point. No one can predict this reliably, because the very definition of the singularity itself precludes such prediction. Given the accelerating nature of technological change, it is just as hard to predict the world of 2050 from 2009, as it would have been to predict 2009 from, say, 1200 AD. So our topic today is not going to be about the 'what', but rather the 'when' of the Singularity.

How To Get More Bicyclists On The Road
CYCLE TRACK, here along New York City's Ninth Avenue, keeps bicyclists physically separated from motor vehicle traffic. Such designs make riding safer and could boost the number of women cyclists. Monica BradleyFrom Scientific American:
To boost urban bicycling, figure out what women want.
Getting people out of cars and onto bicycles, a much more sustainable form of transportation, has long vexed environmentally conscious city planners. Although bike lanes painted on streets and automobile-free “greenways” have increased ridership over the past few years, the share of people relying on bikes for transportation is still less than 2 percent, based on various studies. An emerging body of research suggests that a superior strategy to increase pedal pushing could be had by asking the perennial question: What do women want?

One of my schoolmasters was fond of saying that there are only two worthwhile forms of worldly immortality: to get a poem in the Oxford Book of English Verse, or to have a mathematical theorem named after you. The British scholar Joseph Needham (1900–1995) was no better than a passable amateur poet, judging by the handful of verses in Simon Winchester’s biography of him. He did have a scientific training, but it was in biochemistry, not math, so there is no Needham’s Theorem, nor even a Needham Conjecture. He does, though, enjoy the rare distinction of having a Question named for him. Not a mere question, but a Question, one that has generated endless discussion and many theories.
