100 Things Your Kids May Never Know About
From Geek Dad/Wired Science:
There are some things in this world that will never be forgotten, this week’s 40th anniversary of the moon landing for one. But Moore’s Law and our ever-increasing quest for simpler, smaller, faster and better widgets and thingamabobs will always ensure that some of the technology we grew up with will not be passed down the line to the next generation of geeks.
That is, of course, unless we tell them all about the good old days of modems and typewriters, slide rules and encyclopedias …

CSI Stone Age: Did Humans Kill Neanderthals?
From Time Magazine:
It is one of the world's oldest cold cases. Sometime between 50,000 and 75,000 years ago, a Neanderthal male known to scientists as Shanidar 3 received a wound to his torso, limped back to his cave in what is now Iraq and died several weeks later. When his skeleton was pieced together in the late 1950s and early '60s, scientists were stumped by a rib wound that almost surely killed him, hypothesizing that it could have been caused by a hunting accident or even a fellow Neanderthal. New research suggests that Shanidar 3 may have had a more familiar killer: a human being.

Historic Snow Event In South America
In Bahia Blanca, a coastal city in the Southern part of the Buenos Aires, the snow storm is heavy and local authorities describe it as the worst snow event in 50 years. Roads are already blocked by snow and ice in the regional. TN news channel reports some areas of the Sierra de La Ventana could pick up even 3 feet of snow, unimaginable to the region.
From Watts Up With That:
Early this Wednesday afternoon, satellite pictures were showing a band of clouds advancing to the North and snow precipitation could no be ruled out in the capital Buenos Aires. In July 9th and 10th 2007 it snowed in the city of Buenos Aires for the first time in 89 years and it could snow again just two years later. Snow was also reported in the capital of Chile Santiago. MetSul Weather Center is not ruling out snow also in Uruguay.

New Discovery Suggests Trees Evolved Camouflage Defense Against Long Extinct Predator
Pseudopanax crassifolius, adult foliage and developing fruit, Mangaweka, Central North Island, New Zealand. The Araliaceae tree has several defences which researchers suggest are linked to the historic presence of moa. Seedlings produce small narrow leaves, which appear mottled to the human eye. Saplings meanwhile produce larger, more elongated leaves with thorn-like dentitions. (Credit: Wikimedia Commons, Public Domain Image)
From Science Daily:
ScienceDaily (July 23, 2009) — Many animal species such as snakes, insects and fish have evolved camouflage defences to deter attack from their predators. However research published in New Phytologist has discovered that trees in New Zealand have evolved a similar defence to protect themselves from extinct giant birds, providing the first evidence of this strategy in plant life.

Living, Breeding Mice Grown From Skin Cells
From Wired Science:
Cells from flakes of skin have grown into living, breeding mice, through a bit of biotechnological wizardry.
This feat helps confirm that reprogrammed adult cells, considered a potentially convenient source of stem cell therapies, share the shape-changing powers of embryonic stem cells.
The goal was to create an animal made entirely from reprogrammed cells, and to confirm that reprogrammed cells “are as good as embryonic stem cells,” said Beijing National Stem Cell Bank director Qi Zhou, co-author of the study published Thursday in Nature.

The Cost Of Maintaning The Climate Industry -- A Commentary
The climate industry is costing taxpayers $79 billion and counting.
The Science and Public Policy Institute announces the publication of Climate Money, a study by Joanne Nova revealing that the federal Government has a near-monopsony on climate science funding. This distorts the science towards self-serving alarmism. Key findings:
The US Government has spent more than $79 billion of taxpayers’ money since 1989 on policies related to climate change, including science and technology research, administration, propaganda campaigns, foreign aid, and tax breaks. Most of this spending was unnecessary.

Testing Relativity, Black Holes And Strange Attractors In The Laboratory
Through the optical-mechanical analogy, metamaterials and other advanced optical materials can be used to study such celestial phenomena as black holes, strange attractors and gravitational lenses. Here an air-GaInAsP metamaterial mimics a photon-sphere, one of the key black hole phenomena in its interactions with light. (Credit: Xiang Zhang)
From Science Daily:
ScienceDaily (July 22, 2009) — Even Albert Einstein might have been impressed. His theory of general relativity, which describes how the gravity of a massive object, such as a star, can curve space and time, has been successfully used to predict such astronomical observations as the bending of starlight by the sun, small shifts in the orbit of the planet Mercury and the phenomenon known as gravitational lensing. Now, however, it may soon be possible to study the effects of general relativity in bench-top laboratory experiments.

From Live Science:
Futurists have proposed that extinct animals could be resurrected some day via cloning of their DNA extracted from bone or frozen tissue.
There is little agreement on this, but a new project to store tiny samples of tissue from endangered animals at New York's natural history museum again prompts questions on whether this approach might be insurance against extinction, not just a valuable data repository for biologists.

From Science Daily:
ScienceDaily (July 22, 2009) — New developments in a substance which emits brilliant light could lead to a revolution in lighting for the home and office in five years, claims a leading UK materials scientist, Professor Colin Humphreys of Cambridge University. The source of the huge potential he foresees, gallium nitride (GaN), is already used for some lighting applications such as camera flashes, bicycle lights, mobile phones and interior lighting for buses, trains and planes.
But making it possible to use GaN for home and office lighting is the Holy Grail. If achieved, it could reduce the typical electricity consumption for lighting of a developed country by around 75% while delivering major cuts in carbon dioxide emissions from power stations, and preserving fossil fuel reserves.

Massive New Zealand Quake Moves Country West
From Yahoo News/AP:
WELLINGTON, New Zealand – Southern New Zealand has moved slightly closer to the east coast of neighboring Australia as a result of a massive earthquake last week off the country's South Island, a scientist said Wednesday.
The magnitude 7.8 quake, centered in the ocean near Resolution Island in the country's Fiordland region, twisted South Island out of shape and moved its southern tip 12 inches (30 centimeters) closer to Australia, seismologist Ken Gledhill said.
Gledhill, director of government-owned GNS Science's "GeoNet" national earthquake monitoring project, said the island's geographic shift showed the immensity of the forces involved.

John S. Barry, Main Force Behind WD-40, Dies at 84
From CNBC:
John S. Barry, an executive who masterminded the spread of WD-40, the petroleum-based lubricant and protectant created for the space program, into millions of American households, died on July 3 in the La Jolla neighborhood of San Diego. He was 84.
The cause was pulmonary fibrosis, a lung disease, said Garry Ridge, president and chief executive of the WD-40 Company.
The company says surveys show that WD-40, the slippery stuff in the blue and yellow aerosol can, can be found in as many as 80 percent of American homes and that it has at least 2,000 uses, most discovered by users themselves. These include silencing squeaky hinges, removing road tar from automobiles and protecting tools from rust.

Unsung Heroes Save Net From Chaos
From BBC:
Crack teams of volunteers keep the net online and functioning, according to leading internet lawyer Jonathan Zittrain of Harvard University.
The way data is divided up and sent around the internet in many jumps makes it "delicate and vulnerable" to attacks or mistakes, he said.
However, he added, the "random acts of kindness" of these unsung heroes quietly keep the net in working order.
Professor Zittrain's comments came at the TED Global conference in Oxford.
Incidents such as when the Pakistan government took YouTube offline in 2008 exposed the web's underlying fragility, he explained.

For Scientists, Moon Rocks Tell Story Of A Young Earth
From Philadelphia Inquirer:
For 40 years, the rocks hauled back from the moon have been changing the history of the Earth as we knew it.
The lunar rocks suggest that a smaller planet slammed into ours 4.5 billion years ago, creating the moon and enlarging the Earth. They tell the tale of a storm of space debris violently pounding both the Earth and moon, perhaps triggered by a dramatic reshuffling of the entire solar system.
Scientists today are still studying those rocks, hoping to decipher whether life had already emerged before the near-apocalyptic pummeling 3.9 billion years ago - and, incredibly, survived.

Scientists Capitalize On Extended Solar Eclipse
On Wednesday, 2009 July 22, a total eclipse of the Sun is visible from within a narrow corridor that traverses half of Earth. The path of the Moon's umbral shadow begins in India and crosses through Nepal, Bangladesh, Bhutan, Myanmar and China. After leaving mainland Asia, the path crosses Japan's Ryukyu Islands and curves southeast through the Pacific Ocean where the maximum duration of totality reaches 6 min 39 s. A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and the Pacific Ocean. (Credit: F. Espenak / NASA's Goddard Space Flight Center)
From Science Daily:
ScienceDaily (July 22, 2009) — Scientists at an observatory outside Hangzhou joined residents and tourists across China and India in observing the longest total solar eclipse in a century and probably the most-viewed ever.
The moon's shadow traced a path across the world's two most populous countries before racing across the Pacific, providing a view of totality for five minutes and 36 seconds for scientists gathered here from around the world as part of the Williams College Eclipse Expedition.

Human Stabbed A Neanderthal, Evidence Suggests
Steven Churchill of Duke University is holding a replica of a Neanderthal-type spear (left hand) and a spear thrower and dart (right hand) that would have been similar to weapons used by early modern humans tens of thousands of years ago. Credit: Duke Photo by Les Todd.
From Live Science:
Newly analyzed remains suggest that a modern human killed a Neanderthal man in what is now Iraq between 50,000 and 75,000 years ago. The finding is scant but tantalizing evidence for a theory that modern humans helped to kill off the Neanderthals.
The probable weapon of choice: A thrown spear.
The evidence: A lethal wound on the remains of a Neanderthal skeleton.
The victim: A 40- to 50-year-old male, now called Shanidar 3, with signs of arthritis and a sharp, deep slice in his left ninth rib.

Made In China: The Monster Dust Cloud That Completed A Full Circle Of The Globe In Just Thirteen Days
From The Daily Mail:
It was a natural phenomenon that would have tested the limits of even Mr Muscle.
Scientists in Japan have found that clouds generated by a massive dust storm in China's Taklimakan desert in 2007 completed more than one full circle around the planet in just 13 days.
And measuring around 1.9 miles vertically and up to 1,242 miles horizontally, the dust cloud - which formed in the northwestern region of Xinjiang - stayed in that formation the whole way.

How To Use Your iMac As A Second Screen
From Popular Mechanics:
Can you use your iMac's built-in monitor as a second screen for another computer? The answer is yes. Here's how.
Q:
My iMac has a built-in monitor. Is there a way of using this as a second screen for another computer?
A:
When it comes to screen space, you can never go overboard. Large monitor and multiscreen set-ups make it easy to multitask, and have been shown by a number of studies to boost productivity. It’s a shame, then, that Apple doesn’t build video input jacks into its iMacs—these all-in-one computers have a built-in monitor, and it’d be nice to be able to use it with other systems. This would be particularly useful for laptop users looking for a way to expand screen space when they aren’t on the road.
But even without an input jack, you can still put an iMac to work as an external monitor for another computer. You’ll need a program called ScreenRecycler, which employs what is called the VNC, or Virtual Network Computing, protocol. VNC is usually used as a way to allow one computer to remotely access and control another, but ScreenRecycler uses it to turn the second computer into an adjunct monitor. Note, though, that while the second screen can come from any type of computer (even a laptop), the computer you’re working on has to be a Mac.

A Reprogrammable Space Probe Design For Mission Multitasking in Orbit
From Popsci.com:
Multi-purpose hardware lets Japanese satellite change its mission on the fly.
Right now, thousands of satellites are circling the Earth. They're a diverse bunch. Some relay telephone calls, some spy on North Korea, some monitor the weather. But they all have one thing in common: each can only do one thing. A spy satellite can't suddenly start forecasting storms, and a communications satellite can't study asteroids.
Well, that's all about to change.
Researchers at the Institute of Space Systems at the University of Stuttgart, Germany, have designed a variable-function satellite that can alter its mission on the fly.

Evolutionary Origins of Your Right and Left Brain
In the human brain the left hemisphere controls language, the dexterity of the right hand, the ability to classify, and routine behavior in general. The right hemisphere specializes in reacting to emergencies, organizing items spatially, recognizing faces and processing emotions.

From Scientific American:
The division of labor by the two cerebral hemispheres—once thought to be uniquely human—predates us by half a billion years. Speech, right-handedness, facial recognition and the processing of spatial relations can be traced to brain asymmetries in early vertebrates
The left hemisphere of the human brain controls language, arguably our greatest mental attribute. It also controls the remarkable dexterity of the human right hand. The right hemisphere is dominant in the control of, among other things, our sense of how objects interrelate in space. Forty years ago the broad scientific consensus held that, in addition to language, right-handedness and the specialization of just one side of the brain for processing spatial relations occur in humans alone. Other animals, it was thought, have no hemispheric specializations of any kind.

ScienceDaily (July 20, 2009) — The potential for a huge Pacific Ocean tsunami on the West Coast of America may be greater than previously thought, according to a new study of geological evidence along the Gulf of Alaska coast.
The new research suggests that future tsunamis could reach a scale far beyond that suffered in the tsunami generated by the great 1964 Alaskan earthquake. Official figures put the number of deaths caused by the earthquake at around 130: 114 in Alaska and 16 in Oregon and California. The tsunami killed 35 people directly and caused extensive damage in Alaska, British Columbia, and the US Pacific region*.

Five Human Achievements That Could Top Walking on the Moon
From Popsci.com:
Forty years after Apollo 11, a look forward at the world-changing discoveries that could match--or even top--humankind's first steps on the moon.
Possibly the single most influential event in the public's interest in science and technology (not to mention one of humankind’s greatest adventures), the Apollo 11 mission touched the collective dreams of millions, while pushing science and technology swiftly forward at an unprecedented pace.
But in the decades since man first walked on the moon, science has advanced so rapidly that technology which even a few years ago might have been considered magic has become commonplace. Even so, it would be naïve to assume that Apollo 11 ever represented science and technology’s pinnacle, and that nothing forthcoming will similarly explode the world’s collective dreams and perceptions of what it means to be human.

"This has all the hallmarks of an impact event, very similar to Shoemaker-Levy 9," said Leigh Fletcher, an astronomer at NASA's Jet Propulsion Lab in Pasadena, California. "We're all extremely excited."

Photo Of Space Shuttle's Belly Shows Dings
From Scientific American:
Before docking with the International Space Station (ISS) on Friday, space shuttle Endeavour performed a backflip maneuver so that crew members on the station could check the shuttle's heat shield for damage. Earlier in the week, as the shuttle lifted off from Kennedy Space Center in Florida, pieces of foam insulation fell off the orbiter's external fuel tank, striking the shuttle and carving small nicks [white specks on right edge] into several of the tiles that make up the thermal shield.

From AP:
BANGKOK — Millions of people across Asia will witness the longest total solar eclipse that will happen this century, as vast swaths of India and China, the entire city of Shanghai and southern Japanese islands are plunged into darkness Wednesday for about five minutes.
Streams of amateur stargazers and scientists are traveling long distances to witness the once-in-a-lifetime event.
Astronomers hope the eclipse will unlock clues about the sun, while an astrologer in Myanmar predicts it could usher in chaos. Some in India are advising pregnant relatives to stay indoors to follow a centuries-old tradition of avoiding the sun's invisible rays.

From Reuters:
CAPE CANAVERAL, Florida (Reuters) - The U.S. investment in the Apollo space program, which landed men on the moon, paid off handsomely, unlike the $100 billion plowed into the International Space Station, Apollo's pioneering astronauts said on Monday.
""We opened the door to future of exploration by touching down on another body," Apollo 11 astronaut Buzz Aldrin, the second man to set foot on the moon, said at a press conference commemorating the 40th anniversary of the first moon landing.
The United States staged six successful missions to the moon between 1969 and 1972, then developed the space shuttles and later, the space station.

From ABC News:
For Some, Going to the Moon Became a Spiritual, Philosophical Event.
In the history of humanity, only 24 men have shared the experience.
Forty years ago today, the first of the two dozen astronauts to fly to or around the moon rocketed away from Earth to make history. Twelve had the chance to walk on the moon's surface, though only nine of those are still alive today.
When they returned to Earth, they were scientists and explorers with no peers, at the pinnacles of their careers.
But for some the adventure was so epic it changed the course of their lives. Inspired and transformed by seeing Earth shrink to the size of their thumbs, many let new philosophical and spiritual sensibilities guide them. Others chose entirely new career paths.

From Science Daily:
ScienceDaily (July 20, 2009) — A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy's Pacific Northwest National Laboratory will determine if their innovative approach can safely and economically extract and convert heat from vast untapped geothermal resources.
The goal is to enable power generation from low-temperature geothermal resources at an economical cost. In addition to being a clean energy source without any greenhouse gas emissions, geothermal is also a steady and dependable source of power.

Apollo 11 Moon Landing: Top Quotes From The Mission That Put Man On The Moon
From The Telegraph:
Apollo 11 reached the moon's surface 40 years ago today with Neil Armstrong and his fellow astronauts Buzz Aldrin and Michael Collins on board. Here are some key quotes from the mission that put the first men on the moon.
"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." President John F. Kennedy announces his intention to put a man on the Moon before a joint session of Congress on May 25 1961
"No nation which expects to be the leader of other nations can expect to stay behind in this race for space...We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard." John F. Kennedy explains his lunar ambitions in a speech at Rice University on September 12, 1962

From Science Daily:
ScienceDaily (July 20, 2009) — AFOSR-funded researchers at the University of Rochester are using laser light technology that will help the military create new forms of metal that may guide, attract and repel liquids and cool small electronic devices.
Dr. Chunlei Guo and his team of researchers for the project discovered a way to transform a shiny piece of metal into one that is pitch black, not by paint, but by using incredibly intense bursts of laser light. The black metal created, absorbs all radiation that shines upon it.

From Live Science:
My main research interest is physiology in extreme environments, particularly those with low levels of oxygen.
Animals that thrive in such "hypoxic" environments are ideal species to investigate for how their physiology responds. In addition, studying adaptations to hypoxia in animals at high altitude, during hibernation, or in diving environments may provide insight for understanding and treating human medical issues, such as heart attack and stroke.

2010: A New Space Odyssey Beckons
From The Independent:
The world is on the verge of new manned exploration of the solar system – and, this time, environmentalists are backing it.
This weekend, 40 years after man first landed on the Moon, more human beings than ever before are orbiting on a single spacecraft. In 1969, three men squeezed into Apollo 11's command module, a craft little bigger than a Mini.
Yesterday, the International Space Station, now as large as a four-storey house, yet speeding at 17,239mph, took on board the crew of the shuttle Endeavour: 12 men, one woman – seven Americans, two Russians, two Canadians, one Japanese and a Belgian. During a two-man space-walk, the crew added a four-ton porch – an outdoor shelf for experiments – to the station.

From Yahoo News/AP:
WASHINGTON – The measure of what humanity can accomplish is a size 9 1/2 bootprint. It belongs to Neil Armstrong, the first man on the moon. It will stay on the moon for millions of years with nothing to wipe it away, serving as an almost eternal testament to a can-do mankind.
Apollo 11 is the glimmering success that failures of society are contrasted against: "If we can send a man to the moon, why can't we ..."
What put man on the moon 40 years ago was an audacious and public effort that the world hasn't seen before or since. It required rocketry that hadn't been built, or even designed, in 1961 when President John F. Kennedy declared the challenge. It needed an advance in computerization that had not happened yet. NASA would have to learn how to dock separate spaceships, how to teach astronauts to walk in space, even how to keep them alive in space — all tasks so difficult experts weren't sure they were possible.

July Eclipse Is Best Chance To Look For Gravity Anomaly
From New Scientist:
From remote observatories on the Tibetan plateau to a cave in a Shanghai suburb, Chinese researchers are poised to conduct an audacious once-in-a-century experiment. The plan is to test a controversial theory: the possibility that gravity drops slightly during a total eclipse.
Geophysicists from the Chinese Academy of Sciences are preparing an unprecedented array of highly sensitive instruments at six sites across the country to take gravity readings during the total eclipse due to pass over southern China on 22 July. The results, which will be analysed in the coming months, could confirm once and for all that anomalous fluctuations observed during past eclipses are real.
