The new super-coyotes of eastern North America

November 25, 2015

coywolves20151031_STP001_0

Eastern North America is home to millions of a new breed of coyote, or maybe new species — the coy wolf, which typically has 25 percent wolf DNA and 10 percent dog DNA.

The eastern coyote, or coy wolf, has the cunning of a coyote and the ferocity of a wolf.  Like the western coyote and unlike the eastern timber wolf, it is at home on the open prairie.  Like the timber wolf and unlike the western coyote, it is at home in the deep woods.  Unlike both, it is at home in cities.

An estimated 20 coy wolves inhabit New York City, living on garbage, rodents and small pets.  They have been seen in Boston and Washington, D.C.  Evolution never stops.

What it means to be truly pro-life

August 16, 2015

In 2010, a woman named Sarah Gray gave birth to identical twin boys.  One of them had birth defects and died after a few days.  She and her husband Ross donated the Thomas’s eyes and liver, along with cord blood from Thomas and his twin brother Callum, for scientific research.

A few years later Sarah and Ross Gray learned what use had been made of their child’s remains.

The Schlepens Eye Research Institute in Boston used Ross’s eyes in a study that one day might contribute to a cure for corneal blindness.

Thomas’s retinas were given to the University of Pennsylvania, where they were used in a study that one day might contribute to a cure for retinoblastoma, the most common form of eye cancer in children.   The retina tissue is so valuable that some of it is being saved for future research.

Researchers at the Duke University Center for Human Genetics found subtle genetic differences in the cord blood that might help explain anencephaly, the genetic defect that killed Thomas.  The liver went to a biotech company named Cytonet, which used it to study the best way to freeze liver tissue.

Sarah Gray, who already had worked in public relations for non-profit organizations, became director of marketing for the American Association of Tissue Banks.

The Grays’ decision to donate their baby’s remains for scientific research shows what it means to be truly pro-life.

Coyotes in New York and Chicago by Lance Richardson for Slate.

150731_WILD_CoyoteLIC.jpg.CROP.promo-xlarge2Coyotes now inhabit New York, Chicago and other big American cities.  Lance Richardson thinks they may well fit the urban and suburban environment better than the rural environment.

Coyotes eat rats and mice.  They eat feral cats, which prey on songbirds.  In suburbs, where hunters are forbidden to discharge firearms, they keep the deer population down.

Farmers and ranchers kill coyotes because coyotes destroy poultry and livestock.  But in cities and suburbs, most pets and other domestic animals are locked up, and coyotes survive by eating vermin.

Meet the electric life forms that live on pure energy by Catherine Brahic for New Scientist.

Scientists have discovered bacteria that eat and breathe electrons, and they can be found nearly everywhere.  All life and all chemical reactions are based on a flow of electrons, but these bacteria survive on electricity in its purest form.

Scientists under siege by climate change deniers

July 12, 2015

Climate scientists have spent the past several decades warning humanity about a dire threat to civilization—a threat they think is much worse than the public realizes.  But their reward for this warning has been to be villified and harassed.  Some of them suffer burnout under the stress of being relentlessly attacked.

As John H. Richardson pointed out in Esquire, the scientists have been right so far—

The physical evidence becomes more dramatic every year: forests retreating, animals moving north, glaciers melting, wildfire seasons getting longer, higher rates of droughts, floods, and storms—five times as many in the 2000s as in the 1970s.

hottestyearIn the blunt words of the 2014 National Climate Assessment, conducted by three hundred of America’s most distinguished experts at the request of the U. S. government, human-induced climate change is real—U. S. temperatures have gone up between 1.3 and 1.9 degrees, mostly since 1970—and the change is already affecting “agriculture, water, human health, energy, transportation, forests, and ecosystems.”

But that’s not the worst of it. Arctic air temperatures are increasing at twice the rate of the rest of the world—a study by the U. S. Navy says that the Arctic could lose its summer sea ice by next year, eighty-four years ahead of the models—and evidence little more than a year old suggests the West Antarctic Ice Sheet is doomed, which will add between twenty and twenty-five feet to ocean levels.

The one hundred million people in Bangladesh will need another place to live and coastal cities globally will be forced to relocate, a task complicated by economic crisis and famine—with continental interiors drying out, the chief scientist at the U. S. State Department in 2009 predicted a billion people will suffer famine within twenty or thirty years.

And what has been the scientists’ reward for alerting us to this peril?

The scientists … … have been the targets of an unrelenting and well-organized attack that includes death threats, summonses from a hostile Congress, attempts to get them fired, legal harassment, and intrusive discovery demands so severe they had to start their own legal-defense fund, all amplified by a relentless propaganda campaign nakedly financed by the fossil-fuel companies.  [snip]

which-makes-more-sense-smlNo one has experienced that hostility more vividly than Michael Mann, who was a young Ph.D. researcher when he helped come up with the historical data that came to be known as the hockey stick—the most incendiary display graph in human history, with its temperature and emissions lines going straight up at the end like the blade of a hockey stick.

He was investigated, was denounced in Congress, got death threats, was accused of fraud, received white powder in the mail, and got thousands of e-mails with suggestions like, You should be “shot, quartered, and fed to the pigs along with your whole damn families.”  Conservative legal foundations pressured his university, a British journalist suggested the electric chair.

In 2003, Senator James Inhofe’s committee called him to testify, flanking him with two professional climate-change deniers, and in 2011 the committee threatened him with federal prosecution, along with sixteen other scientists.

Technology primarily benefits those who own it

June 29, 2015

jobs.5x650I can remember 50 and 60 years ago when people worried about what Americans would do with all the affluence and leisure time that would result from automation.   Today that seems like a cruel joke.

Technology primarily benefits those who own it.  Applied science primarily benefits those who fund it, or at least reflects what the funders are interested in.  There can be spillover effects that benefit everyone, but these don’t necessarily happen of their own accord.

I came across a good article on this topic in Technology Review.  The lesson I draw from it is (1) technology is not a substitute for social and economic reform and (2) there is a need for scientific and technological research outside the domains of for-profit corporations and the military.

Whom do you believe about climate change?

June 3, 2015

global-warming-planetPaul Craig Roberts, who was Assistant Secretary of the Treasury during the Reagan administration, has this to say about climate change.

Climate change is a controversy.  What appear to be independent scientists say that the climate is warming due to greenhouse gases produced by human activity. This warming, apparently measurable, has many impacts on sea levels, and on plant, animal, sea, and bird life, as well as food supply for a heavily populated earth.  [snip]

As far as I can tell the polluting corporations have sufficient think tanks and research institutes to neutralize the independent scientists.  If one is not a climate expert, which I am not, one doesn’t really know.  However, I have learned in my many years that an independent voice is far more reliable than a paid voice. 

Possibly climate change is occurring because of solar activity or because of activity inside the earth itself.  The attention should not be on the cause but on the fact.  First establish the fact, then look for the cause.

My view of this is that life depends on climate, and it doesn’t take a lot of change in one direction or the other to create problems for life.  This fact makes climate change an important issue, and corporations should stop paying people to lie about it.  [snip]

Climate change, if real, is clearly a much greater threat than Muslim terrorists or alleged Chinese and Russian hegemonic aspirations.  Therefore, Washington should spend some of the one trillion dollars Washington blows on the military/security complex on arriving at the best conclusion about climate change and its remedies, if any.

The United States is a strange country.  The population accepts the destruction of privacy and civil liberty out of fear of essentially non-existent terrorists created by propaganda, but ignores the threat of climate change presented by independent scientists, a threat amplified by the ongoing multi-year drought in California and the western US.

via Climate Change – The Unz Review.

Those who accept the reality of human-caused climate change are the U.S. Department of Defense, Pope Francis and Saudi Arabia’s oil minister, Ali al-Naimi, who has announced his country’s intention convert to solar energy for its needs by 2040-2050.

Pro-science religion and anti-science religion

What this chart indicates is that the big religious split in the United States is not between Protestants and Catholics, or among Christians, Jews and Muslims, but between pro-science religion and anti-science religion.

This chart is based on a 2007 survey by Pew Research.  It will be interesting to see if the 2014 survey is significantly different.

Strong opposition to Darwinism in Israel

March 30, 2015

evolution-views

The United States is exceptional among economically-advanced nations in the large percentage of the population who reject Darwin’s theory of evolution.

But the USA has a partner in this respect.  A large percentage of the population of Israel also reject evolution.

us_il_evo3

Religious fundamentalists—that is, those who believe that Scripture should be taken as literal fact as well as teaching a lesson—are strong in both countries, and are politically allied to right-wing nationalists.

Right-wing nationalism is not inherent in religious fundamentalism.  The Old Order Amish are fundamentalists.  But when fundamentalism and nationalism are allied, they make a powerful and dangerous force, because the nation and its military are treated as if they are sacred.

The Likud Party in Israel is close to the Republican Party in the United States, in spite of the fact that most Jewish citizens in the United States support the Democrats.

I believe that is because the Likud supporters and Republicans have an affinity in their leaders’ assertive nationalism and in their appeal to religious fundamentalist voters.   The majority of Jewish people in the United States, on the other hand, are liberal humanitarians who accept the conclusions of modern science.

There’s no proof human sex pheronomes exist

March 14, 2015

There’s no scientific evidence that human sex pheronomes exist.  Belief in human sex pheronomes derives from a an inconclusive paper at a scientific conference sponsored by a perfume company.

A fragrance company named Erox supplied two scientists with molecules called androstadiene and estratetraenol, which it identified as “putative human pheronomes”.   The scientists determined that these substances, when injected into the human nose, caused a response in the human nasal passages, and published a paper in 1991 saying they could indeed be pheronomes.

Erox was founded by David Berliner, a former professor at the University of Utah.   The university and Luis Monti-Bloch, one of the two psychiatrists who did the study, owned stock in Erox.   The scientific paper was published at a 1994 scientific conference on mammalian pheronomes sponsored by Erox.   Monti-Bloch later went to work for Erox, which patented androstadiene and estratetraenol and incorporated them into its new perfumes and advertising campaigns.

In 2000, a respected scientist named Martha McClintock did a study indicating that androstadiene improved the mood of women and that estratraenol improved the mood of men, but neither her study nor the earlier study made the claim that they were human sex pheronomes nor cited any evidence they produced human sexual arousal.

Human pheronomes might exist.  It’s possible.  But at the present time, the scientific evidence is lacking.

Darwin’s theory and American exceptionalism

As this chart shows, we Americans are less likely to believe in Darwin’s theory of evolution than the people of any European nation.

Oddly, though, we are more likely to believe in social Darwinism (although we don’t call it that)—the idea the law of life is survival of the fittest, and society does not exist so that people can cooperate for mutually beneficial ends, but so that the population can be sorted into winners and losers.

Populist Former Senator Jim Webb Could Give Hillary Clinton Major Headaches in 2016 by Lynn Stuart Parramore for Alternet.

I’ve long admired Senator James Webb, the former Senator from Virginia.  A Vietnam veteran and Secretary of the Navy in the Reagan administration, he switched from the Republican to the Democratic party out of disgust for the Bush administration’s subservience to Wall Street.  He has criticized the Obama administration on the same grounds.

Webb is an opponent of reckless military intervention abroad, a critic of the “war on drugs” and mass incarceration and a friend of working people.

I admire Senator Elizabeth Warren of Massachusetts for the way she stands up to Wall Street, but I agree with Webb on a broader range of issues than I do with her (for example, she goes along with the administration’s war policies).

David Graeber on funding scientific research

September 22, 2014

Common sense suggests that if you want to maximize scientific creativity, you find some bright people, give them the resources they need to pursue whatever idea comes into their heads, and then leave them alone. Most will turn up nothing, but one or two may well discover something.

But if you want to minimize the possibility of unexpected breakthroughs, tell those same people they will receive no resources at all unless they spend the bulk of their time competing against each other to convince you they know in advance what they are going to discover.
