Ancient Cave Women 'Left Home' -- BBC

Analysis of early human-like populations in southern Africa suggests females left their childhood homes, while males stayed at home.

An international team examined tooth samples for metallic traces which can be linked to the geological areas in which individuals grew up.

The conclusion was that while most the males lived and died around the same river valley, the females moved on.

Similar patterns have been observed in chimpanzees, bonobos and modern humans.

Details of the study are published in a letter in Nature.

Electrons Are Almost Perfectly Round, Scientists Discover -- The Telegraph

Electrons may be the most round natural objects in the universe, a study has discovered.

Researchers at Imperial College London have made the most accurate measurement yet of the shape of an electron, finding that it is almost a perfect sphere.

Experts found that the subatomic particles differ from being perfectly round by less than 0.000000000000000000000000001cm.

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.

My Comment: So much for all of that schooling that I received on how the Hawaiian islands were formed.

Cosmic Explosion Is New Candidate For Most Distant Object In The Universe -- Science Daily

ScienceDaily (May 25, 2011) — A gamma-ray burst detected by NASA's Swift satellite in April 2009 has been newly unveiled as a candidate for the most distant object in the universe. At an estimated distance of 13.14 billion light years, the burst lies far beyond any known quasar and could be more distant than any previously known galaxy or gamma-ray burst. Multiple lines of evidence in favor of a record-breaking distance for this burst, known as GRB 090429B for the 29 April 2009 date when it was discovered, are presented in a paper by an international team of astronomers led by former Penn State University graduate student Antonino Cucchiara, now at the University of California, Berkeley.

Did The Military Cause The Tornadoes That Devastated Joplin, Mo.?

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.

Scientists Detect Earth-Equivalent Amount of Water Within the Moon -- Science Daily

ScienceDaily (May 26, 2011) — There is water inside the moon -- so much, in fact, that in some places it rivals the amount of water found within Earth.

The finding from a scientific team including Brown University comes from the first-ever measurements of water in lunar melt inclusions. Those measurements show that some parts of the lunar mantle have as much water as Earth's upper mantle.

Babies Are Capable of Complex Reasoning -- Live Science

Babies are sophisticated mini-statisticians, a new study finds, capable of making judgments about the probability of an event they've never seen before.

Using a computer model, researchers were able to accurately predict what a baby would know about a particular event if given certain information. The model may be useful in engineering artificial intelligence that reacts appropriately to the world, said study researcher Josh Tenenbaum, a cognitive scientist at the Massachusetts Institute of Technology. The study also demonstrates just how savvy baby brains are, Tenenbaum told LiveScience.

U.S. Congress Getting Ready To Tax The Internet

How Will States Tax Internet Downloads? Congress May Decide -- Epicenter

Here’s an interesting conundrum, posed by Representative Dennis Ross (R-Florida), at a House Judiciary subcommittee hearing held on Monday:

“Imagine you are sitting in Dulles airport in Virginia, waiting for a flight back to Florida,” Ross began in his opening remarks. “You download a music file from Apple, which is headquartered in California. The music is sent to you via a server in Oklahoma.”

Which of these states should be allowed to tax the sale?

Without a “clear national rule,” he warned at the hearing, “all four states may attempt to tax the transaction.”

My Comment: Another tax grab .... get ready for it.

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 Eradication Decision Is Deferred Again

The viral disease was eradicated over 30 years ago. BBC

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.

Bronze Age relic: Archaeologists have found the remains of around 100 bodies in the Tollense Valley in northern Germany, including this fractured skull

'Earliest' Bronze Age Battle Site Containing 100 Bodies Found On German River Bank -- The Daily Mail

Fractured skulls and broken bones found on a German river bank could point to the earliest site of a Bronze Age battle ever discovered.

Archaeologists uncovered the remains of around 100 bodies in the Tollense Valley in northern Germany, suggesting brutal hand-to-hand combat between warring tribes.

Bones had been battered, skulls were fractured and one body has an arrowhead buried more than 2cm inside it.
