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 …

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

Government Monopsony Distorts Climate Science, says SPPI -- Trans World News

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 Stltoday:

WASHINGTON -- The best time to learn a foreign language: Between birth and age 7. Missed that window?

New research is showing just how children's brains can become bilingual so easily, findings that scientists hope eventually could help the rest of us learn a new language a bit easier.

"We think the magic that kids apply to this learning situation, some of the principles, can be imported into learning programs for adults," says Dr. Patricia Kuhl of the University of Washington, who is part of an international team now trying to turn those lessons into more teachable technology.

Gates Puts Feynman Lectures Online


From New York Times:

Microsoft Chairman Bill Gates believes that if he had been able to watch physicist Richard Feynman lecture on physics in 1964 his life might have played out differently.

Mr. Gates, of course, is legendary as a Harvard University dropout who went on to create the world’s most successful software firm. He has told associates that if had watched the lectures earlier in his life he might have become a physicist instead of a software entrepreneur.

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

The same social structures that drive Wikipedia also keep the net healthy

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.
