Air Pollution In Ancient Egypt

This mummy was discovered in Dakhleh Oasis, a remote outpost in southwest Egypt and lived around 1,800 years ago, at a time when the Romans occupied Egypt. Although much of the mummy remains are lost, the area around the lungs, where particulates were found, is well preserved. CREDIT: Photo courtesy Dakhleh Oasis Project.

Egyptian Mummies Hold Clues of Ancient Air Pollution -- Live Science

Ancient Egyptians may have been exposed to air pollution way back when, according to new evidence of particulates in the lungs of 15 mummies, including noblemen and priests.

Particulates, tiny microscopic particles that irritate the lungs, have been linked to a wide array of modern-day illnesses, including heart disease, lung ailments and cancer. The particulates are typically linked to post-industrial activities, such as fossil-fuel burning.

From New Scientist:

SEEMINGLY random acts of violence by bottlenose dolphins on porpoises could be down to sexual frustration among young males.

Cases of the cetaceans killing other creatures for no apparent reason have been reported in UK waters. Now bottlenose dolphins have been seen attacking harbour porpoises in the Pacific Ocean. Crucially, these observations show for the first time that the attackers are young males (Marine Mammal Science, DOI: 10.1111/j.1748-7692.2011.00474.x).

Why We Need A Good Night’s Sleep

A Good Night’s Sleep Isn’t a Luxury; It’s a Necessity -- New York Times

In my younger years, I regarded sleep as a necessary evil, nature’s way of thwarting my desire to cram as many activities into a 24-hour day as possible. I frequently flew the red-eye from California, for instance, sailing (or so I thought) through the next day on less than four hours of uncomfortable sleep.

But my neglect was costing me in ways that I did not fully appreciate. My husband called our nights at the ballet and theater “Jane’s most expensive naps.” Eventually we relinquished our subscriptions. Driving, too, was dicey: twice I fell asleep at the wheel, narrowly avoiding disaster. I realize now that I was living in a state of chronic sleep deprivation.

How the Brain Processes Faces: Neural System Responsible for Face Recognition Discovered -- Science Daily

ScienceDaily (June 1, 2011) — Each time you see a person that you know, your brain rapidly and seemingly effortlessly recognizes that person by his or her face.

Until now, scientists believed that only a couple of brain areas mediate facial recognition. However, Carnegie Mellon University's Marlene Behrmann, David Plaut and Adrian Nestor have discovered that an entire network of cortical areas work together to identify faces. Published in the current issue of the Proceedings of the National Academy of Sciences (PNAS), their findings will change the future of neural visual perception research and allow scientists to use this discovery to develop targeted remedies for disorders such as face blindness.

In Search of Habitable Worlds: The Older the Planet, the Greater Chance There's Life -- Time

To date, the Kepler space telescope has found more than 1,200 likely planets orbiting stars beyond the sun — quite a haul for a satellite that's been flying for just over two years. The true prize Kepler is hunting for, of course, is not just any planet, but one that's a twin of Earth — about the size of our world, orbiting in a zone where the temperature range is like ours. All that would make it a prime place to look for life. Finding such a not-too-hot, not-too-cold world is probably just a matter of time, but even then, there will be one more factor to consider: how old the planet is.

800-Mile-Wide Hot Anomaly Found Under Seafloor Off Hawaii -- National Geographic

Findings contradict long-held theory that a plume directly fuels Hawaii.

Hawaii's traditional birth story—that the volcanic islands were, and are, fueled by a hot-rock plume running directly to Earth's scorching core—could be toast, a new study hints.

Scientists say they've found solid evidence of a giant mass of hot rock under the seafloor in the region. But it's not a plume running straight from the core to the surface—and it's hundreds of miles west of the nearest Hawaiian island.

Is It The End For The Paperback? Kindle E-Book Outsells Print Versions For First Time Ever -- the Daily Mail

Sales of digital e-books have outstripped real books for the first time, according to Amazon.

Four years after the launch of electronic novels, the firm announced it has sold 105 e-books for every 100 printed books over the past six weeks.

My Comment: We predicted this years ago .... but it is still a surprise to now know that this point has been reached.

Robots Learning Their Own Language

The 'Lingodroids' Learning Language via IEEE Spectrum

Robots Learn To CreateTheir Own Spoken Language -- Popular Science

Having a computer for a brain has its perks, but it has its drawbacks as well. Language is a tough concept for robots, as words can convey the abstract as well as the concrete and robots have trouble knowing the difference (and grasping the abstract). That makes human-machine interaction less than intuitive for humans and confusing to ‘bots. But Australian researchers are hoping to change that by teaching robots to communicate verbally in a language of their own creation, the same way humans did.

Beware Of The Coming Zombie Apocalypse

Will Budget Cuts Leave Us Unprepared For Zombie Apocalypse? -- ABC News

If zombies ever start taking over the planet, the U.S. Centers for Disease Control and Prevention (CDC) says we'd better be prepared for it.

If the undead really start roaming the earth looking for fresh brains to eat, we can't rely on our ability to shoot 'em dead the way people do in video games or in horror flicks. Instead, the agency says, we need to treat it like any other disaster.

Working as a Team, Autonomous Swarming 'Bots Quickly Explore and Map Structures -- Popular Science

A swarm of intelligent, autonomous robots from Georgia Tech may soon be leading the charge into dangerous and uncertain situations, providing valuable mapping intel to first responders, military, or police behind them. A team of researchers there have developed a team of small, rolling robots that can autonomously communicate with one another to quickly build a detailed floor plan map of an entire structure and beam it to nearby humans.

Planets More Numerous Than Believed

An artist's depiction illustrates a Jupiter-sized planet wandering free in interstellar space. The new findings appear to confirm the existence of many such planets. (NASA / JPL-Caltech / May 19, 2011)

Planets May Be Vastly More Numerous Than Believed -- L.A. Times

Researchers say that millions of Jupiter-sized planets are wandering in our galaxy far from any star. The findings suggest that there may be twice as many planets as stars in the Milky Way, perhaps several times as many.

The Milky Way galaxy may be filled with millions upon millions of Jupiter-sized planets that have escaped their solar systems and are wandering freely in space, researchers said Wednesday in a finding that seems certain to make astronomers rethink their ideas about planetary formation.

Scientists had previously thought that about 20% of stars had massive planets attached to them, but the new results reported in the journal Nature suggest that there are at least twice as many planets as stars, and perhaps several times as many.

In The Bleak Light Of The Depression: Rare Colour Photographs Of The Era That Defined A Generation -- Daily Mail

It was an era that defined a generation. The Great Depression marked the bitter and abrupt end to the post-World War 1 bubble that left America giddy with promise in the 1920s. Near the end of the 1930s the country was beginning to recover from the crash, but many in small towns and rural areas were still poverty-stricken. These rare photographs are some of the few documenting those iconic years in colour. The photographs and captihttp://www.blogger.com/img/blank.gifons are the property of the Library of Congress and were included in a 2006 exhibit Bound for Glory: America in Color. The images, by photographers of the Farm Security Administration/Office of War Information, shed a bleak new light on a world now gone with the wind.
