China Announces First Panda From Frozen Sperm
From Yahoo News/AP:
BEIJING – China announced the first successful birth of a panda cub from artificial insemination using frozen sperm, giving a new option for the notoriously poor breeders, officials said Friday.
Panda females have only three days a year in which they can conceive — one reason their species is endangered.
Female panda You You (pronounced Yo Yo) gave birth to the new cub Thursday morning at the Wolong Giant Panda Research Center in southwestern Sichuan. It is You You's third baby, and the 10th panda cub born at Wolong this year.

Money Relieves Pain
Money dulls physical pain and eases the sting of rejection, new research shows.From Live Science:
Money dulls physical pain and eases the sting of social rejection, new research shows.
Through six experiments, psychologists and a marketing professor probed the power of money as a proxy for social acceptance. Among their results, they found that merely touching bills or thinking about expenses paid affected the participants both physically and emotionally.
Because it affects pain, money may be a clue to how the brain evolved to process social interactions, the researchers wrote in a paper published in the June edition of the journal Psychological Science.

New NASA Administrator Delays Ares Launch, Decries "Path We Are On"
Bolden Looks Ahead: NASA administrator Charles Bolden testifies at his confirmation hearing before the Senate on July 8, 2009. NASA/Bill Ingalls From Popsci.com:
Charlie Bolden rips off the Spock mask, and the space agency delays its new rocket test until Halloween
Former NASA administrator Mike Griffin once likened himself to Spock in his rational, emotionally-detached approach. Now Griffin's replacement, Charles Bolden, seems ready to inject new passion into a space agency that is struggling to reevaluate both long term goals and its vision for space exploration.
The new administrator choked up five times during a speech to agency employees on Tuesday where he pushed back against criticism that President Obama is uncommitted to space exploration, according to the Washington Post. Part of that emotional upwelling came as Bolden described meeting with the Apollo 11 astronauts on the 40th anniversary of the first moon landing.

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?
A painting imagines the world of Neanderthal menMansell / Time Life Pictures / Getty
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 NewsThe 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.

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.
