Can Organic Food Feed the World? New Study Sheds Light On Debate Over Organic Vs. Conventional Agriculture -- Science Daily

ScienceDaily (Apr. 25, 2012) — Can organic agriculture feed the world? Although organic techniques may not be able to do the job alone, they do have an important role to play in feeding a growing global population while minimizing environmental damage, according to researchers at McGill University and the University of Minnesota.

A new study published in Nature concludes that crop yields from organic farming are generally lower than from conventional agriculture. That is particularly true for cereals, which are staples of the human diet -- yet the yield gap is much less significant for certain crops, and under certain growing conditions, according to the researchers.

17 Equations That Changed the World

How 17 Equations Changed The World -- Brain Pickings

What Descartes has to do with C. P. Snow and the second law of thermodynamics.

When legendary theoretical physicist Stephen Hawking was setting out to release A Brief History of Time, one of the most influential science books in modern history, his publishers admonished him that every equation included would halve the book’s sales. Undeterred, he dared include E = mc², even though cutting it out would have allegedly sold another 10 million copies. The anecdote captures the extent of our culture’s distaste for, if not fear of, equations. And yet, argues mathematician Ian Stewart in In Pursuit of the Unknown: 17 Equations That Changed the World, equations have held remarkable power in facilitating humanity’s progress and, as such, call for rudimentary understanding as a form of our most basic literacy.

Unique And Rare Diamond Up For Sale

Rare Royal Diamond Up For Sale -- The Telegraph

An extremely rare, aristocratic Beau Sancy diamond, which has passed through the royal families of France, England, Prussia and the Netherlands' House of Orange, is to go up for auction at Sotheby's.

The stone, a 35-carat modified 'pear double rose cut' diamond belonging to Georg Friedrich, Prince of Prussia and head of the former ruling dynasty of the German empire, is expected to fetch betweem $2m (£1.24m) and $4m (£2.47m).

Chairman of Sotheby's jewellery in Europe and the Middle East, David Bennett, who sold a pink diamond for $46.2m (£28.5m) in 2010 which was a record for any jewel at auction, said estimating the value of a stone like the Beau Sancy was difficult given its rarity.

The Power And Reach Of Apple

Steve Jobs

Latest Record Results Show Apple a Bigger Global Power Than Most Nations -- Daily Beast

The tech behemoth is not just a cool computer/phone/tablet company, but a multibillion-dollar ecosystem and society with more influence and clout than most countries.

Yet again, Apple announced record sales and earnings. Yet again, its “Jobs report” stood in stark contrast to the monthly official jobs report. For the past four years, as the U.S. economy has stumbled, Apple has soared. As millions have lost jobs or stayed underemployed, Apple has sold more phones, iPads, and computers than most thought possible. While its success certainly has come at the expense of competitors such as Research in Motion (maker of the BlackBerry) and Nokia, it has generated tens of billions in revenue and sold tens of millions of devices by reaching new customers and not simply taking market share. And it has seen its most dramatic success during one of the worst economic slumps in the developed world.

What Causes 'Brain Freeze'

Cause Of Brain Freeze Revealed -- Live Science

Most people have likely experienced brain freeze — the debilitating, instantaneous pain in the temples after eating something frozen — but researchers didn't really understand what causes it, until now.

Previous studies have found that migraine sufferers are actually more likely to get brain freeze than people who don't get migraines. Because of this, the researchers thought the two might share some kind of common mechanism or cause, so they decided to use brain freeze to study migraines.

Costs of 'Dirty Bomb' Attack In Los Angeles -- Science Daily

ScienceDaily (Apr. 23, 2012) — A dirty bomb attack centered on downtown Los Angeles' financial district could severely impact the region's economy to the tune of nearly $16 billion, fueled primarily by psychological effects that could persist for a decade.

The study, published by a team of internationally recognized economists and decision scientists in the current issue of Risk Analysis, monetized the effects of fear and risk perception and incorporated them into a state-of-the-art macroeconomic model.

My Comment: My gut tells me that the costs will be greater than $16 billion.

Should Facebook And Twitter Be Monitored For Terrorists?

Monitoring Twitter And Facebook Could Foil Terrorists -- The Telegraph

The security services need to make greater use of social media such as Facebook and Twitter to track criminals and terrorists, the former head of GCHQ has said.

Sir David Omand said there was increasing use of social media to communicate and that the police and MI5 need to make use of the technology to keep suspects under surveillance.

If they failed to do so, there was a danger that such websites could become a “secret space” where criminals, paedophiles and terrorists could communicate unhindered, he said.

However, Sir David said the Government had to make it clear in what circumstances they would hack into an individual’s account.

Mind-Controlled Robot For Paraplegics Unveiled -- The Telegraph

A robot that can be controlled by the brainwaves of a paraplegic person wearing an electrode-fitted cap has been unveiled.

A paralysed man at a hospital in the Swiss town of Sion demonstrated the device, sending a mental command to a computer in his room, which transmitted it to another computer that moved a small robot 37 miles away in Lausanne.

The system was developed by Jose Millan, a professor at the Federal Polytechnic School of Lausanne who specialises in non-invasive interfaces between machines and the brain.

How Bee Navigation May Assist Transportation And Travel

Bee Navigation Aids Robot Aircraft -- Cosmos

A scientist’s passion for bees and their remarkable flying skills is opening up undreamed-of possibilities in human transportation and travel.

Air travel is likely to become a great deal safer, more precise and efficient in future - thanks to the humble honeybee. From take-off to landing, both piloted and pilotless aircraft as well as ground vehicles are now starting to employ the vision and navigation strategies of these remarkable flying insects.

A wide range of aerial tasks that are repetitive or dangerous for humans, such as checking reservoirs, inspecting power transmission lines, bushfire and weather monitoring, mapping and exploring, and crop dusting as well as defence roles may soon be carried out based on what we have learned from bees. One day their abilities may even help us to explore Mars.

Six Traits Of Human Behavior

Human Nature: Six Things We All Do -- New Scientist

WHAT sort of creature is the human? The obvious answer is a smart, talkative, upright ape with a penchant for material possessions.

But what about the more subtle concept of human nature? That is more controversial. Some deny it exists, preferring to believe that we can be anything we want to be. They cannot be right.

Although we exhibit lots of individual and cultural variations, humans are animals, and like all animals we have idiosyncrasies, quirks and characteristics that distinguish us as a species. An invading alien would have no trouble categorising us but, being so close to our subject matter, we struggle to pin down the essence of humanness.

Where Is The Dark Matter?

Dark Matter Is Missing In Sun's Neighborhood? -- National Geographic

Substance isn't "where we needed it" to match theories, researcher says.

Dark matter is mysteriously missing from the sun's neighborhood, according to a new study that could provide ammunition for skeptics who argue that the invisible substance is just an illusion.

"There will be people claiming dark matter doesn't exist because of this result," predicted study leader Christian Moni-Bidin, an astronomer at Chile's University of Concepción.

"These observations alone do not prove that dark matter does not exist. Still, it is not where we expected it and where we needed it."
