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.

FYI: Why Are Escalators So Dangerous?

Crikey! Hazardous Crocs Getty Images/Washington Post

From Popular Science:

The escalator was patented in 1892, and the design hasn’t changed much since then. The landing platforms make entry and exit dicey endeavors—particularly when the moving stairs disappear beneath them, and all manner of clothing and body parts can get stuck. In recent years, escalators have torn the big toe from a Croc-wearing child in Singapore, bucked dozens of riders in Washington, D.C., and strangled a tipsy sushi chef when the hood of his sweatshirt got caught in the gap between the stairs and the landing platform.

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.

Tornadoes Caused by Military?: Recent Events Fuel Conspiracy Theories -- ABC News

It's an astonishing claim: The tornado that ravaged Joplin, Mo., last Sunday, killing at least 125 people, was not a random act of nature but the result of an obscure military-backed research program in Alaska that shoots radio waves into the upper atmosphere.

Here's another one: The shooting rampage in Tucson last January that killed six people and wounded 13, including Rep. Gabrielle Giffords, was an elaborate government hoax that used actors to portray the victims.

NASA's Mars Rover Spirit To Be Shut Down

NASA's Mars rover Spirit, shown in an artist's rendering, was expected to serve a three-month mission, but it provided scientists with a trove of information over more than six years of operation. (Reuters)

NASA Rover Spirit 'Revolutionized' How We See Mars -- L.A. Times

As the Martian rover falls silent for good, JPL scientists mourn Spirit's loss and celebrate its remarkable achievements that continued for years beyond its expected lifetime.

It was supposed to roam the surface of Mars for only three months and cover a distance of just a few hundred yards. Instead, NASA's Spirit rover traveled nearly five miles over five years, finding geological evidence that the Red Planet had once been warm and wet enough to have harbored life. Even after it got hopelessly stuck in the powdery soil of Gusev crater, the rover continued to make discoveries and beamed them to scientists millions of miles away.

Smallpox-Destruction Deadline Delayed For 3 Years -- Wall Street Journal

Global health officials delayed setting a deadline Tuesday for destroying the last known stocks of smallpox for at least three years, a compromise that will enable the U.S. and Russia to continue researching medications to counter a bioterror attack.

The consensus at the World Health Assembly, the decision-making body of the World Health Organization, came after a contentious debate stretching over two days. It represents a compromise for the U.S., Russia and more than two dozen other countries that wanted to keep the virus stocks for at least another five years. Iran, China, Thailand and other countries objected to that timetable and some of its provisions.

Surprise Find In Kepler Planet Hunt: Lots Of Multi-Planet Systems -- Christian Science Monitor

NASA's Kepler spacecraft, which is searching for Earth-mass planets orbiting sun-like stars, is finding hundreds of candidate planets, and many more multi-planet systems than expected.

Two years into a 3-1/2-year mission, NASA’s Kepler spacecraft, hunting for planets orbiting some 165,000 stars in the constellation Cygnus, is uncovering planet candidates by the hundreds.

Many of these inhabit multi-planet systems that are unexpectedly flat – the inclination of the planets’ orbits within each of these systems are essentially the same, a feature that may hold clues about how these systems formed and evolved.

Controversial Three Gorges Dam Has Problems, Admits China -- Christian Science Monitor

The world's largest hydroelectric project was designed to tame the flood-prone Yangtze River and to generate clean energy. But the water is becoming polluted, and regular landslides are making life near the dam dangerous.

The Chinese government made a rare admission Thursday of something that millions of people living around the Three Gorges dam know only too well: There is a dark side to the country’s proudest engineering achievement.

My Comment: Critics have been saying the same thing for years .... I guess are now listening.

The Coming Population Explosion

Graph From The Economist

Can The World Feed 10 Billion People? -- Raj Patel, Foreign Policy

With an exploding global population -- and Africa's numbers set to triple -- the world's experts are falling over themselves arguing how to feed the masses. Why do they have it so wrong?

The world's demographers this week increased their estimates of the world's population through the coming century. We are now on track to hit 10 billion people by 2100. Today, humanity produces enough food to feed everyone but, because of the way we distribute it, there are still a billion hungry. One doesn't need to be a frothing Malthusian to worry about how we'll all get to eat tomorrow. Current predictions place most of the world's people in Asia, the highest levels of consumption in Europe and North America, and the highest population growth rates in Africa -- where the population could triple over the next 90 years.

Australia's Honeybees To Be Devastated By The Asian Bee

Asian Bee Will Devastate Australia's Honeybees -- Cosmos

SYDNEY: Scientists have predicted the spread of a wild and highly invasive species of bee across Australia, and being a natural carrier of the deadly varroa mite, will likely devastate current populations of farmed honeybees.

The Asian honeybee (Apis cerana) was first identified in the north-eastern city of Cairns in 2007, after having spread from Papua New Guinea to the Solomon Islands. According to experts at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), these bees are impossible to farm and are prone to robbing farmed honeybees of their hoards and building nests in houses and letterboxes.

Lung Cancer Rates Double In Women Over 60 Since The 1970s

Lung Cancer Rates Double In Women Over 60 Since 1970s -- The Telegraph

Lung cancer rates for retired women have more than doubled since the mid-1970s because of an increase in the number of female smokers, new figures have shown.

Rates for British women aged 60 and over rose from 88 per 100,000 in 1975 to 190 per 100,000 in the latest figures from 2008.

Almost 5,700 women over 60 were diagnosed with lung cancer in 1975. This jumped to more than 15,100 in 2008.

The rise, revealed by Cancer Research UK, can almost all be attributed to increase in smoking among women in the latter half of the last century.

Men on the other hand have seen a dramatic decrease in rates as millions have stopped smoking over the same period.

My Comment: More proof that smoking increases the chances of getting cancer.

Could 'Supermoon' Next Week's 'Supermoon' Disrupt Earth's Weather?

Earth will be at its closest point - some 221,567 miles away - to the moon in 19 years on March 19. Some fear the 'lunar perigee' will affect our climate pattern

Could 'Supermoon' Next Week Disrupt Earth's Weather? -- The Daily Mail

Moon comes at its closest approach for 19 years

It promises a unique photo opportunity for amateur astronomers.

Earth will next week be at its closest point to the moon since 1992.

The March 19 event - known as a 'lunar perigee' - will see the moon pass just 221,567miles away from our planet.

Using Google Earth To Find Ancient Tombs In The Saudi Desert

Google Earth maps showed 1,977 structures built of basalt stone from the surrounding lava field in Jeddah, including various pendants, or circular mounds similar to collapsed tombs with processions of small stone piles branching out from them (A, B, C and D).

Thousands of Tombs in Saudi Desert Spotted From Space -- Live Science

Little is known about the archaeology of Saudi Arabia, as the government has historically forbid aerial photographs of the landscape and religious sensitivities have made access tricky. But Google Earth is changing that. Satellite images available via the Web-based 3-D map program show that large portions of the country hold a wealth of archaeological remains that predate Islam and may be several thousand years old.

We Should Learn To Speak To Dolphins Before Talking To Aliens

To Talk With Aliens, Learn to Speak With Dolphins -- Wired Science

The Kepler Space Telescope announced a new bonanza of distant planets this month, reconfirming that solar systems, some possibly hosting life, are common in the universe.

So if humanity someday arrives at an extraterrestrial cocktail party, will we be ready to mingle? At the Wild Dolphin Project in Jupiter, Florida, researchers train for contact by trying to talk with dolphins.

Behavioral biologist Denise Herzing started studying free-ranging spotted dolphins in the Bahamas more than two decades ago. Over the years, she noticed some dolphins seeking human company, seemingly out of curiosity.

My Comment: This is a novel idea .... but I am more hopeful that the aliens will be better at communicating to 'us' than 'us' communicating to dolphins.

Reverse Engineering The Brain -- Cosmos

SYDNEY: Can we really create a computer which can discern complex patterns, recognise facial expressions, decode meaning from speech and even understand our emotions? It's only a matter of time, says a leading researcher.

That’s the vision that drives Terrence Sejnowski, a leading authority on computational neuroscience who is trying to understand the inner-workings of the human brain – how we learn, form memories and interact with our environment – in order to develop computer devices that can emulate these processes.

From Popular Science:

With more nations seeking nuclear weapons and nuclear power at home poised for resurgence, America's bases and labs are bustling with activity. In the post-9/11 world, many, but not all, facilities have restricted access. Justin Nobel visited several sites to see where we stand on nuclear deterrence, detection and the latest reactor technologies. He also uncovered several below-the-radar nuclear tours open to the general public.
