The Secrets Of Ancient Rome

From The Guardian:

The discovery of a major new archaeological site in Italy is a reminder that the world is still stuffed with secrets.

Look down from a height at any landscape in this slanting autumn light, and you'll see that the ground is only a thin blanket thrown over the remains of the past. The faint marks of fields and walls, houses and roads, show up even in the heart of cities – in relics as humble as the outline of a lost Edwardian rose bed, marring the bland green perfection of a suburban lawn.

Video: The Robot That Can Turn Into A Car

From The Daily Mail:

A Japanese inventor has designed a robot that can change from robot to vehicle in seconds - and can even offer 'piggy-backs' on its shoulders.

Looking a bit like Optimus Prime, the lead character of the Transformers films, the robot is even prepared to battle, especially when it takes exception to sharing the stage with a smaller robot.

The three-foot high creation took part in the Robo-One competition, which aims to drive the creation of humanoid-shaped robots.

How Aviation Can Come Clean

From Technology Review:

Advanced technology won't be enough for the industry to meet its own greenhouse-gas targets.

Last week the global aviation industry called on the United Nations to establish a single, worldwide policy for reducing aviation greenhouse-gas emissions, in an attempt to avoid a costly network of regional regulations. The industry proposed two primary goals--that by 2020 it should stop increasing its greenhouse emissions, and that by 2050 it should cut its emissions by 50 percent compared to 2005 levels.

Students Build The Solar Homes Of The Future

From Popular Mechanics:

For the Solar Decathlon, 20 teams of college students strive to build the most technologically savvy sun-powered house. For two weeks in October their homes go head to head in a contest to consume the least energy.

On a hot and bright California day, the red steel frame of a half-built house, its footprint a jagged stamp on the landscape, glints in the sunshine beaming down on Santa Clara University. Crawling around the crescent-shaped structure, workers holler measurements, fasten sheathing and snap chalk lines. They’re wearing hard hats and tool belts, and the noise of steel swatting plywood sounds unmistakably like a job site. But this is hardly a construction crew out of central casting.

With Drone Shortage, Air Force Pilots Train With Cessnas Dressed Up Like Predators

Surrogate Predator: A Cessna 182 wears the sensor ball

From Popular Science:

Converted manned aircraft with mounted sensor balls will imitate Predators and Reapers during military exercises.

A high demand for Predators and Reapers on the front lines has led the U.S. Air Force to take an unusual step: asking human pilots to mimic the drones for training purposes back in the States.

Cessna 182 aircraft have become converted "Surrogate Predators" with the installation of a "Predator ball" that typically serves as the surveillance and tracking eyes for drone operators. Such Predator balls give the manned Cessnas the ability to lock onto targets and track them.

Uncivilisation: The Dark Mountain Manifesto

From New Statesman:

We have, it seems, led the planet into the age of ecocide. Can civilisation survive the unavoidable environmental catastrophe? To stand a chance we will need cool heads, not fiery dreams.

During the past century empires crashed, new states foundered, utopian projects failed and entire civilisations melted down. Revolutionary change was the norm, as it has been throughout modern times. Yet today many of us assume our present way of life will last for ever, and any suggestion that it may be facing intractable difficulties is dismissed as doom-mongering. The result is that the precariousness of modern civilisation is underestimated and the impression that things can go on indefinitely, much as they do now is touted as hard-headed realism.

New Ancient Fungus Finding Suggests World's Forests Were Wiped Out In Global Catastrophe

From Science Daily:

ScienceDaily (Oct. 2, 2009) — Tiny organisms that covered the planet more than 250 million years ago appear to be a species of ancient fungus that thrived in dead wood, according to new research published October 1 in the journal Geology.

The researchers behind the study, from Imperial College London and other universities in the UK, USA and The Netherlands, believe that the organisms were able to thrive during this period because the world's forests had been wiped out. This would explain how the organisms, which are known as Reduviasporonites, were able to proliferate across the planet.

Exploring The Mysteries Of The Ocean Floor

From Live Science:

About three years ago, Emily Beal — a graduate student in geosciences at Penn State —eagerly boarded the deep-diving research submersible called Alvin, bound for the bottom of the ocean.

After squeezing into Alvin’s titanium sphere, Beal began her plunge to the ocean floor with more than a tad of claustrophobia. Alvin was just big enough to hold her, the submersible’s pilot, and Penn State colleague Chris House. Fortunately, as Beal peered out of Alvin’s plate-sized portholes during her descent, her claustrophobia quickly gave way to pure, unalloyed exhilaration.

Elderly Women Sleep Better Than They Think, Men Sleep Worse

From Science Daily:

ScienceDaily (Oct. 1, 2009) — A study in the Oct.1 issue of the journal Sleep shows that elderly women sleep better than elderly men even though women consistently report that their sleep is shorter and poorer.

Women reported less and poorer sleep than men on all of the subjective measures, including a 13.2 minute shorter total sleep time (TST), 10.1 minute longer sleep onset latency (SOL), and a 4.2 percent lower sleep efficiency. When sleep was measured objectively, however, women slept 16 minutes lon¬ger than men, had a 1.2 percent higher sleep efficiency, and had less fragmented sleep.

Apple’s Tablet Could Be Print Industry’s Lifeboat

From Gadget Lab:

The more you think about it, the more obvious it is that an Apple tablet would specialize in reviving dead-tree media (i.e., newspapers, magazines and books). All the rumors suggest the device would be a larger iPod Touch/iPhone with a 10-inch screen. Previously Wired.com argued that redefining print would would be a logical purpose for a gadget this size, and Gizmodo today has even more details to prove that this is Apple’s goal with the tablet.

Gizmodo’s Brian Lam cites two people related to The New York Times, who claim Apple approached them to talk about repurposing the newspaper onto a “new device.” Lam notes that Jobs has called the Times the “best newspaper in the world” in past keynotes. (I recall him saying that when introducing the iPhone’s web browser at Macworld Expo 2007.)

Clock Turned Back On Aging Muscles, Researchers Claim

Young, healthy muscle (left column) appears pink and red. In contrast, the old muscle is marked by scarring and inflammation, as evidenced by the yellow and blue areas. This difference between old and young tissue occurs both in the muscle's normal state and after two weeks of immobilization in a cast. Exercise after cast removal did not significantly improve old muscle regeneration; scarring and inflammation persisted, or worsened in many cases. Credit: Morgan E. Carlson and Irina M. Conboy, UC Berkeley

From Live Science:

Scientists have found and manipulated body chemistry linked to the aging of muscles and were able to turn back the clock on old human muscle, restoring its ability to repair and rebuild itself, they said today.

The study involved a small number of participants, however. And the news is not all rosy.

Importantly, the research also found evidence that aging muscles need to be kept in shape, because long periods of atrophy are more challenging to overcome.
