"Study: Hard times better for female fetuses
Posted by the Asbury Park Press on 01/26/06

HEALTHDAY
Males may be the stronger sex, but more females are born during times of stress, research shows.

Nearly two centuries of Swedish genealogy records suggest that pregnant women are more likely to spontaneously abort male fetuses and embryos during times of stress, such as famine. The resulting generations of children are stronger and actually live longer than those born during good times, the researchers contend.

The findings suggest that being conceived in difficult times doesn't hurt the male fetuses who are actually born, said study co-author Ralph Catalano, a professor of public health at the University of California, Berkeley. They do just fine..."

WASHINGTON, Jan. 26 (Xinhuanet) -- U.S. scientists have found a unique gene carried by the H5N1 bird flu strain may be a key factor in making the virus so deadly, local media reported on Thursday.

Researchers at St. Jude Children's Research Hospital in Memphis,Tenn. discovered the gene after a large analysis of samples of about 11,000 flu viruses that Dr. Robert Webster has gathered from around the world since 1976. The samples include about 7,000 bird flu viruses, from poultry, ducks, gulls and other flocks.

Initial results from the genetic analysis showed that all the bird flu viruses studied had the unique gene and none of the human flu viruses did, researchers reported in the journal Science.

They also said people infected with H5N1 flu virus in Vietnam and Thailand had the "avian" version of the flu virus, and so was the case with the 1918 flu pandemic, which killed tens of millions of people globally.

The researchers have completed the first large genetic analysis of more than 300 bird flu viruses from the virus collection. They identified 2,196 bird flu genes and 160 complete genomes. The information are posted in a public genetic database for any scientist to mine it.

The study suggests that two nonstructural proteins, NS1 and NS2,may be key in helping avian virus latch onto and disrupt certain important cellular processes. They are only made once the avian flu virus has infected a cell. However, more evidence are needed to confirm the finding.

The H5N1 bird flu virus was first found to have spread to people in 1997. It resurfaced in 2003 and has since infected at least 152 people and killed 83, according to the World Health Organization.

Scientists fear the virus would soon mutate to become easily transmissible among people and cause a global pandemic similar to the 1918 outbreak. Enditem

Information on reprocessing from the World Nuclear Association
Union of Concerned Scientists
lnternational Institute for Strategic Studies
Signs that the US could be about to overturn a 30-year ban on nuclear fuel reprocessing have been greeted with alarm by environmentalists worried about the dangers of spreading plutonium around the world.

Reports in US newspapers have suggested that the Bush administration is planning to reverse a policy introduced by Presidents Ford and Carter in 1976 and 1977. They promised that the US would not reprocess the spent fuel from nuclear reactors to extract plutonium because of the risk that it could be made into nuclear bombs.

But now US Department of Energy officials are proposing a $250 million programme to restart reprocessing using a new technology known as UREX and developed by the Argonne National Laboratory in Illinois. This chemical separation process produces a mix of plutonium and uranium, which can be recycled to fuel reactors.

"The implications are devastating," says Damon Moglen, from the Union of Concerned Scientists, an environmental lobby group in Washington DC. "This would legitimise the widespread separation and commercial use of plutonium that could be used in nuclear weapons."

It would send the wrong message to potential proliferators like Iran and North Korea and encourage reprocessing in Russia, Moglen argues. "This is the worst possible thing to do," he told New Scientist. "It is a classic example of the US telling the world to do as we say, not as we do."

Yucca Mountain
Bush officials, however, say that the risk of countries diverting plutonium into bombs would be reduced if foreign spent fuel were reprocessed in the US. And they argue that the type of plutonium produced by the UREX process is harder to make into warheads.

Reprocessing could also, officials claim, cut the amount of waste that would have to be disposed of at the proposed repository under Yucca Mountain in the Nevada desert. Without reprocessing, Yucca could quickly fill up with spent fuel, they say.

Details of the administration's plan, known as the Global Nuclear Energy Partnership, are sketchy. Some reports suggest that it will be announced in President Bush's State of the Union address on 31 January, but others say it will not be finalised by then.

"Quite horrific"
Two senior US officials have recently toured Russia, Japan and other countries briefing governments about the plan, according to The Washington Post. The French reprocessing company, Areva, has also suggested that it might win reprocessing contracts from the US.

Mark Fitzpatrick, a former US Department of State expert now with the International Institute for Strategic Studies in London, UK, accepts US assertions that the plan may make plutonium less available to terrorists. But it will also make it more difficult to persuade countries like Iran to forgo enrichment and reprocessing, he argues.

Shaun Burnie from Greenpeace International is less diplomatic. "The emerging plan is quite horrific," he claims. "It will overturn a decades-old US policy and give the green light for global nuclear proliferation."

CocinaCOCINAVanguard Spanish chefs use science to infuse emotion....................Maricel E. Presilla
[email protected]

The top talents of Spain's vanguard experimental cuisine had a mano a mano with some of the most progressive chefs from the United States, Italy, Holland, Japan and Peru last week at Madrid Fusion, an international culinary conference now in its fourth year.
For three days at the Palacio Municipal de Congresos, a sleek conference center on the outskirts of Madrid, the chefs dazzled an eager audience (mainly food professionals and media) with scintillating demonstrations of their latest kitchen exploits -- liofilization, microfiltration and laser technology, among other mind-bending techniques.
The inclusion of stellar American chefs among the honorees (Norman Van Aken) and presenters (Thomas Keller, Charlie Trotter, Wyllie Dufresne, Homaro Cantu) reflects Spain's newly found realization that the United States is also home to a vibrant modern cuisine worth exploring.
Yet in the mano a mano with the top practitioners of Spain's new cuisine, the Basque Juan Mari Arzak and the Catalan Ferran Adri, it was evident that the Spaniards have the upper hand, not necessarily in their full-hearted embrace of science and technology in cooking but in a kind of philosophical maturity with regard to what they want to achieve by this alliance.
''Debemos de dejarnos de puñetas -- lo importante es la emoción'' (``We should stop talking nonsense -- what is important is to create emotion''), Adri said with visible conviction, after showing a video of a rapturous Italian couple having dinner at his El Bulli.
``There will be science, there will be investigation, there will be a quest, but to help cooks infuse emotion into dining. In the end what is important is to have a good time.''
These statements clarified my understanding of a cuisine I had always considered too cerebral, too remote from the pleasure principle, too in love with gadgets at the expense of great flavor. As in past vanguard movements in art and literature, chefs like Adri and Arzak see science as a force for progress, not an end in itself.
For Adri, industrial techniques like sous vide (cooking foods in vacuum-sealed pouches at low temperature to preserve and intensify natural flavors and enhance texture), liofilization (a kind of freeze-drying), or the use of super-cold liquid nitrogen for stunning tableside presentations allow the chef to create visual tricks, sounds and contrasting textures, forms and colors that engage the senses, eliciting emotion.
The new Spanish cuisine is not about putting extraneous elements on a plate just for the sake of the shock effect.
As Arzak put it, ''No se pone nada en el plato por tontería'' (``You should not put anything on the plate out of a silly impulse''). Everything must have a higher purpose. And if you eat his amazing food, as grounded in the soil of his native Basque region as in the rarefied world of science, you will become a believer.
My three-day immersion in food's brave new world convinced me that the new Spanish cuisine exemplified by Adri, Arzak, Martín Berasategui, Joan and Jordi Roca and many others is no fad but a serious movement that is bound to affect the way we cook and eat in ways that might not be readily apparent.
Already in Spain, young chefs are paying close attention to preserving the moist texture of fish by cooking it at lower temperatures for longer periods. Suckling pig cooked slowly in oil or lard to make a confit, its skin later crisped by oven roasting, is now a familiar item in upscale restaurants. New gadgets like the Thermomix, popularized by Adri, that whips and blends while simultaneously cooling or heating, is fast becoming the new Cuisinart. Foams and savory ice creams are part of the Spanish gastronomic vocabulary.
What to call this mold-breaking cuisine? Adri posed this question after enumerating its basic canon, a set of 23 defining principles that range from the definition of cooking as a ''language that can express harmony, creativity, happiness, beauty, poetry, complexity, magic, humor, provocation,'' to the breakdown of the classic order of dishes to the blurring of the rigid barriers between sweets and savories to the need to create a team to execute this complex cuisine.
Three principles in particular caught my attention:
• The new cuisine assumes the use of high-quality ingredients, but every product has the same culinary value regardless of its price. In this scheme, a fresh, organic egg is as noble and valuable as the finest caviar.
• Adri also sees as a sine qua non of the new cuisine the preservation of the original flavor of ingredients regardless of the transformation in their shape, temperature and texture.
• Finally, he posits that the new Spanish cuisine has an emotional link with its surroundings that should not be understood as a direct link with tradition -- ``Lo autóctono como estilo es un sentimiento de vinculación con el entorno.''
``Siento como un tío de Barcelona'' (``I first feel like a guy from Barcelona'').
In all, Adri tries to make sense of a movement that is emotionally Spanish and regional, mindful of its place in history. As for the name he seeks, I would call it Cocina Experimental de Vanguardia Española. The terms ''experimental'' and ''avant-garde'' both point to its groundbreaking, mold-shattering spirit and the pivotal place that science and continuous experimentation play in its development.
As an experimental cuisine, practiced by people who, like Arzak and Adri are inherently curious and fun-loving, it will be changing, flexible, humorous and open as it continues its exciting dialogue with the worlds of science, industry and the arts.
Attending the event was an eye-opening experience that will make me take stock and rethink the way I look at food. I don't see myself rushing to buy a Thermomix, but I realize that Spain's new science-driven cuisine is a movement of far-reaching consequences.

Wa Hoo!! gotta go back an read this stuff.

sumac, The simple answer to yours' above re the female being born during times of stress = my assessment of that = the strongest urge is to reproduce the species in any animal - the strongest link within any species is the female - therefore they are in charge of reproduction.

"Three weeks ago, Secretary of Interior Gale Norton handed over wolf management to the state of Idaho -- the same state that just a few years ago passed a resolution calling for the elimination of wolves "by any means necessary."

And just one week later, Idaho officials announced a draft plan to kill up to 50 wolves to improve elk hunting in the upper Clearwater Basin. That's 75% of the wolf population in one National Forest."

Wow!! I am thinking of naming the Bush Administration the "Bush Gang" - there is just something very wrong with this type action.

Dan,
My understanding of the female offspring being more numerous in times of stress involves a number of posts.

First, I really don't think that the female of the species is in charge of reproduction. In too many cases it amounts to rape or coercion.

But we do know that the male genetic material determines the sex of the offspring. We also know that to become a male, the division and specialization of those initial small number of cells must be changed in important ways. Without those instructions to change direction (coming from genetic coding from the biological father), all offspring will develop as females by default.

We also know that female fetuses and very young infants are more viable (go to full term) and survive early development without deaths or significant problems, as compared to male fetuses and very young infants.

This later point seems to be particularly accentuated during times of stress. The only other hypotheses are that a) the genetic coding from the male to have embryo become male is weaker or defective, or b) the intrauterine environment necessary for that genetic coding to be carried through successfully on a physiological level is less hospitable during times of high stress.

Does chaos reflect the "beyondness" of present understanding - the galactic out there? The human perception that signals laws or order not yet understood in its wholeness, or complexity of interaction with all other systems?

Quote from the fascinating article above re: Feigenbaum's worlk at Los Alamos:

"Chaos breaks across the lines that separate scientific disciplines. Because it is a science of the global nature of systems, it has brought together thinkers from fields that had been widely separated. Chaos poses problems that defy accepted ways of working in science. It makes strong claims about the universal behavior of complexity. The first chaos theorists, the scientists who set the discipline in motion, shared certain sensibilities. They had an eye for pattern, especially pattern that appeared on different scales at the same time. They had a taste for randomness and complexity, for jagged edges and sudden leaps. Believers in chaos--and they sometimes call themselves believers, or converts, or evangelists--speculate about determinism and free will, about evolution, about the nature of conscious intelligence. They feel that they are turning back a trend in science toward reductionism, the analysis of systems in terms of their constituent parts: quarks, chromosomes, or neurons. They believe that they are looking for the whole."

I readily admit to being more than a little confused as to all of the distinctions between the processing of ore to become fuel for either nuclear reactors, or the manufacture of weaponry. By this, I am referring to what Iran supposedly wants to do, what Russia says it will do for Iran (in Russia), and what Iran now appears to be saying that it will do jointly with Russia (where?).

Now we have reprocessing of spent nuclear fuel from reactors, a kind of recycling of these waste products which can then be used to make more fuel for reactors, make weaponry, etc. Coincidentally, or maybe as justification only for the proposed action, are the notions that it would reduce the need for huge amounts of space for its disposal, and that it would somehow keep it out of the hands of the bad guys. Who would presumably grab vaste quantities of it and reprocess it for their own desires to make bombs?

Did I get that about right?

New avant garde approach in some quarters of Spanish cooking seems to ge beyond the Oriental desire to have presentation rise to heights, to something more akin to an encompassing, cross- disciplinary art form.

Is that too much to expect from fuel?

Test to check spray field's impact
Some scientists say site is source of springs pollution

By Bruce Ritchie
DEMOCRAT STAFF WRITER


"What one scientist joked was a "witches' brew" of fluorescent dye was released into the Floridan Aquifer on Thursday to help determine whether wastewater from the city's spray field is reaching Wakulla Springs.

The spray field, where up to 20 million gallons of nutrient-rich wastewater from two city sewage-treatment plants is sprayed on crops, has been identified by scientists as a possible source of nitrogen at Wakulla Springs. The nitrogen has fed the growth of aquatic weeds that have choked the springs' swimming area and the Wakulla River."

ECOLOGY/EVOLUTION: Taking In the Welcome Mat
---------------------------------------------------------------------------Andrew
M. Sugden

Ants are ubiquitous in tropical forests, and they exhibit a wide
variety of
nesting and foraging behaviors that have fascinated naturalists and
ecologists ever since the pioneering of scientific exploration in the
tropics. Despite many decades of intense study and the high visibility
of
ants, Longino has managed to unearth previously unreported nesting
habits
in two endemic Costa Rican ant species in the genus Stenamma. These
ants
build nests in the vertical clay banks of streams, and the entrance to
the
nest is formed by a tunnel through the center of a shallow dish sitting
atop a pedestal of clay or through a similarly shaped disk of soil
lying on
a mound of small stones. In both types of dwelling, a spherical pebble
near
the entrance can be retrieved and used to plug the doorway in times of
danger. Each ant colony maintains several such nests, but occupies only
one
at a time. Because of their colonial habit, ants attract predators, and
much of their nesting repertoire revolves around defense. Hence, it
appears
that the elaborate constructions of Stenamma may minimize the chances
of
attack by marauding hordes of army ants, which are one of the dominant
forces shaping tropical forest ecosystems. --

Nuclear Energy Plan Would Use Spent Fuel

By Peter Baker and Dafna Linzer
Washington Post Staff Writers
Thursday, January 26, 2006; A01



"The Bush administration is preparing a plan to expand civilian nuclear energy at home and abroad while taking spent fuel from foreign countries and reprocessing it, in a break with decades of U.S. policy, according to U.S. and foreign officials briefed on the initiative.

The United States has adamantly opposed reprocessing spent fuel from civilian reactors since the 1970s because it would produce material that could be used in nuclear weapons. But the Bush program, envisioned as a multi-decade effort dubbed the Global Nuclear Energy Partnership, would invest research money to develop technologies intended to avoid any such risk, the officials said.

The program has been the subject of intense debate within the administration, and although a consensus has been reached about the direction, a senior official said it will not be ready for Bush to announce in his State of the Union address Tuesday. Even the discussion has stirred concerns among nuclear specialists and some members of Congress who consider it an expensive venture that relies on unproven concepts and could increase the danger of proliferation.

The notion of accepting other countries' spent fuel at a time when the United States has had trouble disposing of its own nuclear waste could also prove highly controversial."

Dan, with federal protections removed - the state will do as it will with the abundant forests and wildllife. The eco-system works to well for the bush administration. Predator animals CONSERVE - the bushco administration can't fathom the concept. Nor can irresponsible hunters.

Gale Norton works for industry, not for the enviornment.

Norton remains silent after the courts granted a reprieve from aerial "hunting" of wolves in Alaska. Seems the hunts are ILLEGAL!

For all the bush supporters monitoring the thread...
