The Innovative 787 Carries Boeing, And Aviation, Ahead


From Autopia:

Boeing’s 787 Dreamliner looks like any other airliner, so it might be hard for anyone but an airplane geek to get so excited about its inaugural flight. But the energy-efficient airliner is a bold step forward for Boeing, and for aviation.

As much as the 787 Dreamliner looks like the jet that carried you on that cramped, uncomfortable flight last month, almost everything about it is new. From the extensive use of composite materials and advanced aerodynamics to its fuel-efficient Rolls Royce engines and all-electric systems, Boeing is betting the 787 will be the plane to usher in a cleaner, greener future for the airline business.

Surfing A Wave Of Californian Sunshine As America Looks For Renewable Future

The eSolar plant in the Mojave Desert generates enough electricity to power 4,000 homes

From Times Online:

On a dry, scrubby plain on the edge of the Mojave Desert north of Los Angeles, 24,000 mirrors track the Sun’s progress across a clear, blue sky. The neat ranks of heliostats and the computer algorithm that moves them make the Sierra SunTower plant a focal point for a novel type of power generation and a new wave of energy companies looking to turn the search for renewables into successful businesses.

Solar tower technology uses mirrors to reflect sunlight on to a thermal receiver atop a tower. The reflected sunlight boils water inside the receiver to create superheated steam at 440C (824F), which drives a turbine and generates electricity.

The Year In Biomedicine

From Technology Review:

Advances in antiaging drugs, acoustic brain surgery, flu vaccines--and the secret to IQ.

We may look back on 2009 as the year human genome sequencing finally became routine enough to generate useful medical information ("A Turning Point for Personal Genomes"). The number of sequenced and published genomes shot up from two or three to approximately nine, with another 40 or so genomes sequenced but not yet published. In a few cases, scientists have already found the genetic cause of a disorder by sequencing an affected person's genome.

Revenge Of The Chilli: Why Pepper Seeds Are Designed To Burn Your Mouth

Professor Sue Hartley (right) supports volunteer Adam after he eats a Naga chilli

From The Daily Telegraph:

Ever wondered why chilli peppers are so mind-blowingly hot? It's all down to their ultra-effective defense system developed in the ongoing war between plants and animals.

When humans bite down on chillis they crush the seeds the plants want to spread with their molar teeth. The peppers extract their revenge by releasing a mouth-burning mix of chemicals called capsinoids.

Can We Find A Living Planet By 2020?


From Discovery News:

There was a lot of excitement last week about the discovery of a “waterworld” planet called GJ 1214b, as reported on Discovery News by my colleague Ian O’Neill.

This world belongs to an emerging class of planets dubbed “super-Earths.” It is 6.5 times Earth’s mass and nearly three times our diameter. Its mass, diameter and density suggest the planet is largely a ball of water with and icy/rocky core.

From The New York Times:

ROCHESTER — The ceremonial pipe organ of the 18th century was the Formula One racer of its time, a masterpiece of human ingenuity so elegant in its outward appearance that a casual observer could only guess at the complexity that lay within.

Each organ was designed to fit its intended space, ranging in size from local churches where townspeople could worship to vast cathedrals fit for royalty. The builders were precision craftsmen celebrated for their skill in hand-making thousands of moving parts and in shaping and tuning metal and wooden pipes to mimic the sounds of each instrument in an orchestra.
