The Stealth Libertarian campaign of Edward Gonzalez for Congress, as a Republican

From Eric Dondero:

The California primaries were yesterday. And Libertarian Republicans were paying close attention to one race in particular.

This from activist Mike "Mish" Shedlock sent out on his blog and in an email blast two days ago:

If you live in California District 16, please write in Edward Gonzalez. He only needs 2,053 Republicans write-in votes. If you are a Libertarian, do not check the Libertarian box, instead wrote-in Edward Gonzalez as a Republican.

Gonzalez is the Libertarian nominee. But he's simultaneously seeking the GOP nomination for Congress in an overwhelmingly Democrat district, near San Jose. His opponent is longtime incumbent, ultra-liberal Rep. Zoe Lofgren. There is no Republican candidate on the ballot for the race.

There is opposition to the efforts of the Gonzalez campaign. Establishment Republicans mounted their own last minute challenge for a write-in nomination to keep Gonzalez from having two ballot spots. Sources have told LR that the challenge came from the "religious right wing" of the local GOP, not from the Tea Party wing, and suprisingly not from the Arnold Schwarzenegger moderates.

The results should be known later today.

Note from the Editor - if you live in California and you find out the results, please contact LR immediately. Thanks

And so it continues for Center-Right parties in Europe… This time it’s Spain

El marcado libre avanza por todas partes del mundo

From Cliff Thies:

Add Spain to the list of countries in the world indicating they are ready to shift from the socialist-left orientation to a center-right orientation. A recent survey gives the center-right Popular Party (better translated as People's Party) a ten point lead over the Socialist Workers' Party. In the last election, the Socialists eked out a thin, four point victory over the Popular Party.

(See chart for survey at electometro.com)

And this from Reuters, "Spain's Socialists pay high price for crisis":

(Reuters) - Spain's economic crisis has seen support for the minority Socialist government nosedive and increased doubts about its ability to remain at the helm of the eurozone's fourth largest economy.

A 15-billion-euro austerity bill scraped through parliament by just one vote on Thursday, narrowly avoiding setting off a vote of no-confidence.

And if there were any doubts about the national mood, opinion polls in the weekend papers put Prime Minister Jose Luis Rodriguez Zapatero's government as much as 10 points behind the conservative opposition Popular Party (PP).

The next Spanish general elections are due in 2012, but an early election is a possibility though not likely in the near-term...

The Popular Party and its leader Mariano Rajoy could muster sufficient support in parliament for a vote of no-confidence on any pretext, which would mean early elections.

"There's a high probability the PP will win the next election, no matter what, considering the current economy, but Spain really doesn't need an election right now," said professor of economics at Grenada University Santiago Carbo Valverde.

In addition to the two main parties, there are a number of smaller parties, including both center-right and socialist-left nationalist parties in the several "national" regions of Spain. Four governments ago, the Popular Party ruled in coalition with the center-right nationalist parties. Three governments ago, obtaining a majority in the Spanish parliament in its own name, the Popular Party ruled alone. Implementation of the kind of reforms that are needed would be helped by securing a large majority in the parliament, so that even if the Popular by itself won a majority, it should consider forging a coalition with the center-right nationalist parties.

babyGas production by feces of infants.

“BACKGROUND: Intestinal gas is thought to be the cause abdominal discomfort in infants. Little is known about the type and amount of gas produced by the infant’s colonic microflora and whether diet influences gas formation. METHODS: Fresh stool specimens were collected from 10 breast-fed infants, 5 infants fed a soy-based formula, and 3 infants fed a milk-based formula at approximately 1, 2, and 3 months of age. Feces were incubated anaerobically for 4 hours at 37 degrees C followed by quantitation of hydrogen (H2), methane (CH4), carbon dioxide (CO2), hydrogen sulfide (H2S), methanethiol (CH3SH), and dimethyl sulfide (CH3SCH3) in the head-space. RESULTS: H2 was produced in greater amounts by breast-fed infants than by infants in either formula group, presumably the consequence of incomplete absorption of breast milk oligosaccharides. CH4 was produced in greater amounts by infants fed soy formula than by infants on other diets. CO2 was produced in similar amounts by infants in all feeding groups. Production of CH3SH was conspicuously low by feces of breast-fed infants and production of H2S was high by soy-formula-fed infants. CH3SCH3 was not detected. Only modest changes with age were observed and there was no relation between gas production and stool consistency, although stools were more likely to be malodorous when concentrations of H2S and/or CH3SH were high. CONCLUSIONS: Gas release by infant feces is strongly influenced by an infant’s diet. Of particular interest are differences in production of the highly toxic sulfur gases, H2S and CH3SH, because of the role that these gases may play in certain intestinal disorders of infants.”

Big Autism Study Reveals New Genetic Clues, but Also Baffling Complexity | 80beats

DNAResearchers have published the largest-existing study on the genetic causes of autism, comparing 996 autistic individuals to 1,287 people without the condition. Their results, which appear today in Nature, may provide unexplored avenues for treatment research, but also show in new detail the disorder’s sheer genetic complexity. For example, they have found “private mutations” not shared between people with autism and not inherited from their parents.

According to The Centers for Disease Control and Prevention, one in 110 children in the United States has autism spectrum disorder, and that the prevalence of autism among eight-year-olds has increased 57 percent from 2002 to 2006. There is no known cure, although intensive behavioral therapy helps some kids.

Hilary Coon, Ph.D., a lead author on the study and research professor of psychiatry at the University of Utah School of Medicine, said while research shows scientists are making progress in understanding the causes of autism, it is increasingly clear that autism is a multifaceted disorder with both genetic and environmental causes. “We are whittling away at it,” Coon said. “But a brain-related disorder, such as autism, is amazingly complex. It’s not really one entity.” [University of Utah press release]

For this study, researchers at the international Autism Genome Project wanted a closer, more detailed picture of the over 100 genes commonly linked to autism. They looked for rare variants–small deletions or additions to the DNA sequences that make up these genes. They found that people with autism had a higher number of these variants than those without the disorder, and that some of these DNA differences were not inherited. That means these DNA changes occurred either in the egg cell, sperm, or in the developing embryo.

“Most individuals that [sic] have autism will have their own rare form,” genetically speaking, concludes senior author Stephen Scherer, a geneticist at the Hospital for Sick Children in Toronto, Canada. That said, the team found that genes deleted in autistic patients tended to perform similar tasks. Many were involved in aspects of cell proliferation, such as organ formation. A number participated in development of the central nervous system and others in maintaining the cytoskeleton, which protects the cell and helps it move. “These are not random hits in the genome” and clearly have some connection to autism, says Jonathan Sebat, a geneticist at Cold Spring Harbor Laboratory in New York state. [Science Now]

Some believe that looking more closely at these variants may eventually lead to novel treatments.

Two categories of genes were affected more frequently than others: those coding for the neural cell development, and those involved in the signalling or “communication” between cells. Many of these same genes are thought to play a role in other neuro-development disorders. There may even be some overlap with conditions such as epilepsy and schizophrenia, the researchers said. “These and other recent findings have very real potential to lead to the development of novel interventions and treatments for these disorder,” said Louse Gallagher, a professor at Trinity College Dublin, one of the universities in the consortium. [AFP]

So what’s the next step towards such treatments? For now, it’s more big genetics studies. The Autism Genome Project has enrolled another 1,500 families and hopes for their next testing phase to look at people’s complete genomes and exomes (the part of the genome that codes for RNA or protein), reports Nature’s blog The Great Beyond.

The study has been hailed as a positive step by researchers, though one can imagine the parents of autistic children still feeling frustrated by the slow pace of progress. Perhaps to avoid giving false hopes, Dr Gina Gomez de la Cuesta of The National Autistic Society was cautious in her assessment of the study, saying:

“This study furthers our understanding of genetic variation in autism, however there is a great deal more research to be done. Research into autism is constantly evolving but the exact causes are as yet still unknown. The difficulty of establishing gene involvement is compounded by the interaction of genes with the environment. Genetic testing for autism is still a long way off, given that autism is so complex.” [BBC]

Saturn’s Rings May Have Birthed Its Small Moons—and More Could Be Coming | 80beats

SaturnBlueThey’re new, they’re small, and they didn’t make sense.

That’s what could be said for five of the littlest members of Saturn’s expansive satellite family. The largest of this group, Janus, measures barely more than 100 miles in diameter, but it’s the age of these little moons that’s the odd bit. Their clean, crater-free surfaces help reveal that they’re only 10 million years old, meaning they didn’t form the way the planet’s other moons did—from the accretion disk that formed mighty Saturn itself billions of years ago. This week in Nature, astronomers published evidence to support an explanation for that oddity: Those moons formed from Saturn’s rings.

Like so much new knowledge about the sixth planet and its moons, including Titan and Enceladus, the research team’s findings come from the Cassini mission:

Sailing past Saturn’s outer rings, it found lumps of ice up to 100 metres across, ten times bigger than the rings’ other icy particles. For some researchers, the discovery called to mind another intriguing fact: that the moons and the rings share a composition of the purest ice in the Solar System. “When you put all this together, you had the strange feeling that something is going on in the rings’ outer edge,” says Sébastien Charnoz at Paris Diderot University, who was involved in the latest research [Nature].

Some scientists had suspected this explanation, but they lacked the computer power to model how it could happen (even the most powerful machine would struggle to model the trillions of orbits in the solar system’s history). So the team created a simplified model with the ring as a single dimension, tested it out on our own planet and moon’s history, and then applied it to Saturn and its rings. At the out edge of the rings, it works: material can clump together.

“Disks in astrophysics are like pancakes—they spread,” [Charnoz] says, adding that collisions within the disk or ring drive the spreading detritus outward. Once the icy ring particles venture beyond about 140,000 kilometers from Saturn’s center, they become unstable, clumping into tiny protomoons and then moonlets [Scientific American].

As the clumps get bigger, Saturn’s gravity pushes them further out (our own moon is slowly receding from us). While it’s nice to have a workable answer to the puzzle, the bigger implication is that the solar system is alive. Says Charnoz:

“There are still new objects forming in the solar system today. We used to think everything was formed four, five billion years ago, but no! New objects are still forming today” [MSNBC].

A good week for UK science journalism (despite one big fail) | Not Exactly Rocket Science

It’s been an interesting week for UK science journalism. On the one hand, we had a veteran science journalist laying out a manifesto for failure, by suggesting that reporters are messengers with no remit for analysis or fact-checking.

I’m still staring wide-eyed in disbelief over that, but a couple of noteworthy events today have lifted my spirits about the state of the country’s science journalism. For a start, we have Mark Henderson at the Times continuing to understand that the Internet offers interesting possibilities denied to print publication. His interview with our new science minister David Willetts was published in the Times, but also posted in a much fuller form on its blog.

At the Genetic Future blog, Daniel Macarthur broke a brilliant story about a screw-up at personal genomics company 23andme, which ended up with up to 96 people receiving the wrong data. It was a great example of excellent journalism emanating from the blogosphere and both New Scientist and Nature deserve credit for credting Daniel appropriately.

Nature once again shows why it produces some of the best science coverage out there by dissecting two reports that cast suspicion on the WHO’s pandemic response, suspicion that now seems unsubstantiated.

And most excitingly of all, the Guardian have launched the first of their Story Trackers – a new way of telling science stories that Alok Jha described to me as a “slow live-blog”. The idea is that they pick specific big stories and continuously update their coverage for a few days with reactions, comments and links, sourced from other coverage, blog posts, tweets and more. It’s an idea that stems from Alan Rusbridger’s “mutualisation of news” idea that he expounded in his Hugh Cudlipp lecture.

That is, the Guardian realises that there are plenty of other conversations going on about the stories it covers, often by people with more knowledge and expertise, and it is silly to ignore that. It’s the same idea that drove the unconference format so enjoyed by attendees at the ScienceOnline’10 conference. Quoting Rusbridger:

“We feel as if we are edging towards a new world in which we bring important things to the table – editing; reporting; areas of expertise; access; a title, or brand, that people trust; ethical professional standards and an extremely large community of readers. The members of that community could not hope to aspire to anything like that audience or reach on their own; they bring us a rich diversity, specialist expertise and on the ground reporting that we couldn’t possibly hope to achieve without including them in what we do.”

Spot on, and enter the story trackers. By pulling in material from all across the internet, they tap into this rich vein of expertise while providing the people who they’re quoting and linking to with extra traffic. It’s a win-win.

The trackers are also based on the idea of living stories. News stories don’t finish at the point of publication or the lifting of the embargo. There’s a huge amount of reaction and commentary that goes on long after the first words appear in print or pixels. That’s all part of the experience of reading modern news and, again, it’s silly to ignore it and wise to capitalise on it.

For all of the above, I’m feel really quite optimistic about the future of mainstream science journalism in the UK. There are good people doing good things and while my joy will almost inevitably be dashed tomorrow morning, I think it’s wise to highlight the best examples when we see them.

23andMe to Customers: Oh Wait, Those Are Somebody Else’s Genes | Discoblog

23andmeHad her baby been switched at birth in a hospital mishap? That’s what one mother thought after getting her child’s results from the personal genetics testing company 23andMe and finding that his genetic profile was inconsistent with the rest of the family’s. After she finished screaming and crying, she contacted the company. Sorry for the inconvenience, she was told–we just mixed up his sample.

The company that asks clients to spit in vials is now putting its foot in its mouth: it gave up to 96 customers a look at the wrong genes. 23andMe posted an apology, viewable only to clients, on their website.

The Los Angeles Times also published the statement, which blamed the snafu on a processing error at a contractor lab:

“Up to 96 customers may have received and viewed data that was not their own. Upon learning of the mix-ups, we immediately identified all customers potentially affected, notified them of the problem and removed the data from their accounts. The lab is now concurrently conducting an investigation and re-processing the samples of the affected customers and their accurate results will be posted early next week.”

23andme2The statement also says that, pending the results of their investigation, they will “adopt corrective action as warranted,” but states that “23andMe’s personal genetics service remains proven and sound.”

23andMe says the tests can show customers whether they’re at risk for certain diseases, and can reveal their ties to ancestors. While lab mix-ups happen, we’re thankful these tests were not used on impressionable college freshman, suspected cheating spouses, or for sentencing criminals.

World Science Festival: Untangling String Theory | Discoblog

string-theoryOn stage at the World Science Festival on Saturday night, festival co-founder Brian Greene recalled the early days of string theory–the theory that brings together competing ideas in physics by postulating that there exist six or seven extra dimensions beyond space and time.

Greene was a graduate student in physics when string theory got its start, and remembers waking up early each morning to run to the mailbox in search of news of harmony and peace; that is, for signs that the long, obdurate conflict between general relativity and quantum mechanics was resolving itself into a beautiful universe of tiny vibrating strings.

That was in the 1980s. Now, almost thirty years later, the conflict continues, and the strings—though beautifully imagined by artists and scientists—still haven’t made themselves apparent in the form of a testable prediction. This is a big problem for skeptics like Lawrence Krauss, who insist that untestable scientific theories are—well, not really science.

But Krauss, presumably out of deference to his host, didn’t say that on stage on Saturday. Instead, he took a soft approach, presenting the audience with a picture of an anthropological find, a 33,000-year-old wood carving of a half-man, half-lion creature. “Who knows what the artist was thinking when he—or she—created this?” he mused. Perhaps the artist had seen a lion before, and had also seen people, and had imagined the existence of a combination-type-creature.

“Maybe that’s what string theory will look like in another 33,000 years,” Krauss suggested.

Greene said he thought string theory was “a touch more well-motivated than the lion-human,” but agreed that human understanding is a pitiful thing (especially when limited by the senses).

The most effusive string theorist on the panel was Shamit Kachru, who described himself as “still excited”–more like the young, mailbox-happy version of Brian Greene, ever optimistic for the arrival of proof.

John Hockenberry, the panel’s moderator, asked Greene if he thought experimental evidence would come during his lifetime.

“I’d be surprised,” said Greene.

“And in your lifetime?” Hockenberry asked Kachru.

“…I’d be surprised,” conceded the young physicist reluctantly.

“I’d be surprised if we weren’t surprised,” concluded Krauss, before the lights went down.

Dueling Videos: Is Iranian Nuclear Scientist a Defector or Kidnap Victim? | 80beats

AmiriHave you seen this man? If so, please ask him to make up his mind.

Shahram Amiri, a 32-year-old Iranian nuclear scientist, is at the center of an episode of United States-Iran intrigue that just got weirder, thanks to YouTube. Amiri disappeared during his pilgrimage to Saudi Arabia last year, and anonymous U.S. officials confirmed that he defected, presumably bringing information about Iran’s nuclear program. Now he—or someone purporting to be him—appears in two contradictory videos that claim he was either abducted and tortured by the United States or is living happily here and going about his studies.

The first video:

The dark-haired man, appearing unshaven and disheveled, said he was being held against his will in Tucson. “I was kidnapped in a joint operation by the American intelligence, CIA terror and kidnap teams, and Saudi Arabia’s Istikhbarat” spy service, the man said in a grainy video aired in Iran on Monday night. He said he had been drugged before being smuggled out of Saudi Arabia, adding that he had been subjected to “severe torture” and “psychological pressures” [Washington Post].

A very different Amiri showed up in a second video today. He, or someone like him, appears in a professionally shot video sitting in front of some parlor with a globe and a chess board, as if he wants to have a few minutes of our time to talk about life insurance.

In it, the man claiming to be Amiri contradicts many of the claims made in the earlier video, noting he is safely and happily residing in the U.S., though experts say it appears he is reading from a script. “I am free here, and I assure everyone I am safe,” he says in Farsi [Huffington Post].

So is it really him? Iran, of course, has the political motive to make it look like Amiri was a kidnapping victim and not a defector. And it makes no sense at all to think someone held against his will would be handed a Webcam and Internet access to beam his plight back to Iran. So maybe it’s an Iranian fake.

But there are more intriguing possibilities:

“Assuming there is some truth to the fact that he cooperated with CIA, he is either having mental issues or he is just trying to make the Iranians go easier on friends and family of his still inside by pushing the story he left against his will,” said Charles “Sam” Faddis, a retired CIA officer and author of several books on intelligence. He added: “Nobody kidnaps Iranian scientists and drags them against their will to the United States” [Washington Post].

Frankly, the bent and diction of both talks sound like they were written by government propagandists from one side or the other. The weird jockeying and doubletalk will probably continue because political tensions between Iran and the U.S. seem to be escalating: The U.S. just pushed through more diplomatic sanctions against Iran for its nuclear activities, and Iran quashed rumors that it would trade the three American hikers still held there for Amiri. Pressing the case that Amiri was kidnapped, Iran filed a formal complaint with the Swiss. (Switzerland’s envoys handle our business there since official relations with Iran were cut off long ago.)

Living in Bat City: Millions of Mothers, Millions of Pups | Visual Science

These are mother Mexican free-tailed bats emerging from a limestone cave in Texas. They fly as far as 60 miles from the cave, and sometimes a mile or two high, to catch insects. Several million pups (one per mother) are left behind in the cave, where they are packed at densities up to several thousand per square yard. Remarkably, mothers are able to find their pups to nurse them in these dark, noisy caverns. They do so by learning a mental map of the cave geometry, and using a combination of vocal and scent recognition to locate and identify their own pups. As the pups get older they participate more actively in these reunions.

Author of Second Nature: The Inner Lives of Animals, Jonathan Balcombe, on his recent book: “We need a complete overhaul in our relationship with (other) animals. The core reason for this is that they are, like us, highly sentient—intelligent, aware, emotional, perceptive, etc. I studied this species of bat for my PhD. Their excellent memories, individual recognition skills, and their capacity to make fine sensory discriminations (spatial, acoustic and olfactory) to identify their babies are a good illustration of the inner lives of animals.”

Pocket science – bursting bubbles make more bubbles, and snakes on the wane | Not Exactly Rocket Science

Not Exactly Pocket Science is a set of shorter write-ups on new stories with links to more detailed takes by the world’s best journalists and bloggers. It is meant to complement the usual fare of detailed pieces that are typical for this blog.

Bursting bubbles create rings of daughter bubbles

Popping a bubble on a body of water seems like an unspectacular event, but there’s real beauty in what happens if you look at it carefully. For James Bird at Harvard University, that meant filming the exploding bubbles with a high-speed camera. His beautiful videos reveal that contrary to popular belief, a popped bubble doesn’t just vanish. Instead, it gives birth to a ring of smaller daughter bubbles, each of which can produce an even smaller ring when it bursts.

The bubble’s curved nature means that the air inside it is at a higher pressure than air outside it. When a hole forms in the bubble, this pressure difference disappears and the film starts to recedes away. The film experiences an inward force along its surface, but an outward force at its rim – as a result, it folds outwards back onto itself, trapping a donut of air. The donut, however, is unstable and it soon breaks up into several smaller bubbles. The whole process takes place in a few thousandths of a second and it can only happen twice before the daughter bubbles get too small.

This process is surprisingly common. It applies to liquids from water to oil, regardless of their viscosity, and it happens in soapy sinks and foamy oceans alike. Bird also found that the bursting of each daughter bubble released tiny liquid droplets into the atmosphere. These aerosols may be miniscule but they have a few important repercussions. They’ve been implicated in the spread of infectious diseases in swimming pools and hot tubs and they contribute to the cycling of chemicals from the oceans into the atmosphere.

Snakes on the wane (credit to Sciencepunk for the headline)

Snakes

A depressing number of important animal groups are facing massive population crashes, including amphibians, corals and most recently lizards. Now snakes are the latest faction to join this pessimistic list. An international team of scientists led by CJ Reading did a survey of 17 snake populations, covering 8 species from the European grass snake to the African gaboon viper. They found that 11 of the populations have declined at an alarming rate since the mid 1990s, while 5 have remained relatively stable. The crashing populations all showed a “tipping point” trend, where their numbers suddenly and steeply fell over four years, after a lengthy period of stability. They’ve all levelled off since but one decade on, their numbers show no sign of recovering.

The trends are worrying especially because we still have no idea what’s behind them. It’s telling that all of the five stable populations lived in protected areas, while the crashing species hailed from regions troubled by human activity. Their fates could be driven by falling habitat quality and a lack of prey. It’s also notable that all but one of the stable five are wide-ranging and active foragers, while the declining species are typically ambush predators that stay in the same restricted range. These “sit-and-wait” hunters are more vulnerable to human activity that disrupts the habitats they need to hide in, and they usually grow and breed slowly.

Whatever the cause, it seems to be universal. Reading’s team found that tropical species like Nigeria’s rhinoceros viper are experiencing similar population crashes as temperate ones like the British smooth snake, and all within the same period of time. To Reading, this suggests that the declines share a common and widespread cause – climate change would be an obvious candidate but that needs to be tested.

Lady Humpback Whales Make Friends & Meet up for Summer Reunions | 80beats

humpbackScientists have long thought humpbacks loners. New research shows this isn’t so: Researchers have observed some female whale form friendships that last for years. The behavior has only been observed in lady humpbacks of similar age, with the whales going their separate ways during the breeding season, but reuniting in the open ocean each summer. These bonds can be quite strong: the longest association endured for six years.

The study appears in the journal Behavioral Ecology and Sociobiology, and it also found that the whales with the longest-lasting associations gave birth to the most calves–another animal kingdom example that friendship is beneficial. The whales are probably improving their feeding efficiency, suggests lead author Christian Ramp.

“Staying together for a prolonged period of time requires a constant effort. That means that they feed together, but likely also rest together…. So an individual is adapting its behaviour to another one.” [BBC]

When categorizing fraternal sea animals, scientists used to make a dental distinction: tooth-sporting sperm whales, dolphins, and orcas make friends, but baleen whales like the humpback–those whales that use stringy baleen to strain their food out of the water–were thought less social. Says Ramp:

“I was very surprised by the prolonged duration…. I was expecting stable associations within one season, not beyond. I was particularly surprised by the fact that only females form these bonds, especially females of similar age.” [LiveScience]

Snapping pictures of yearly whale visits to the Gulf of St. Lawrence off Canada’s coast since 1997, scientists including Ramp recorded the familiar groupings. As for where the summering whales meet up and how they recognize their old friends, those things are still mysterious.

Ramp wonders whether whaling has made humpbacks’ social pairings increasingly rare since traveling together might make them easier targets, though he says he would need more research to make this conclusion.
