Tribute to the Space Shuttle — video of every mission

July 29, 2011

From the good folks at Nature:

Nature said:

NASA’s 30-year Space Transportation System (STS) program came to an end on 21st July 2011. The Space Shuttle fleet delivered the Hubble Space Telescope, the International Space Station, and dozens of satellites, space probes, crew and supplies. Two Shuttles were lost: Challenger in 1986 and Columbia in 2003. The touchdown of Atlantis at Kennedy Space Center marked the end of an era, after 135 missions. This video shows all of them in chronological order. http://www.nature.com/spaceshuttle

Soundtrack: ‘PX3’ and ‘Retreat! Retreat!’ by 65daysofstatic.

Frank Swain at Sciencepunk added:

No sooner than the smell of low Earth orbit had worn off the space shuttle Atlantis, Nature editor Adam Rutherford was stitching together footage of its final mission into this wonderful tribute to the golden age of manned spaceflight.

So long, Space Shuttle.  We miss you already.

Poisoning the children: Study shows mothers give DDT to their children from breastmilk

July 29, 2011

Too many in the U.S. bury their heads in the sands about the issues, but researchers in Spain and Mozambique wondered whether indoor residual spraying (IRS) with DDT, to fight malaria-carrying mosquitoes, might produce harms to children in those homes.  They studied the issue in homes sprayed with DDT in Mozambique.

It turns out that young mothers ingest DDT and pass a significant amount of it to their children when the children breast feed.

The study itself is behind Elsevier’s mighty paywall, but the abstract from Chemosphere is available at no cost:

Concentration of DDT compounds in breast milk from African women (Manhiça, Mozambique) at the early stages of domestic indoor spraying with this insecticide

Abstract

Breast milk concentrations of 4,4′-DDT and its related compounds were studied in samples collected in 2002 and 2006 from two populations of mothers in Manhiça, Mozambique. The 2006 samples were obtained several months after implementation of indoor residual spraying (IRS) with DDT for malaria vector control in dwellings and those from 2002 were taken as reference prior to DDT use. A significant increase in 4,4′-DDT and its main metabolite, 4,4′-DDE, was observed between the 2002 (median values 2.4 and 0.9 ng/ml, respectively) and the 2006 samples (7.3 and 2.6 ng/ml, respectively, p < 0.001 and 0.019, respectively). This observation identifies higher body burden intakes of these compounds in pregnant women already in these initial stages of the IRS program. The increase in both 4,4′-DDT and 4,4′-DDE suggest a rapid transformation of DDT into DDE after incorporation of the insecticide residues. The median baseline concentrations in breast milk in 2002 were low, and the median concentrations in 2006 (280 ng/g lipid) were still lower than in other world populations. However, the observed increases were not uniform and in some individuals high values (5100 ng/g lipid) were determined. Significant differences were found between the concentrations of DDT and related compounds in breast milk according to parity, with higher concentrations in primiparae than multiparae women. These differences overcome the age effect in DDT accumulation between the two groups and evidence that women transfer a significant proportion of their body burden of DDT and its metabolites to their infants.

Highlights

► DDT increases in pregnant women at the start of indoor spraying with this compound. ► Rapid transformation of DDT into DDE occurs in women after intake of this insecticide. ► The DDT increases in breast milk of women due to indoor spraying are not uniform. ► Breast milk DDT content in primiparae women is higher than in multiparae women. ► Women transfer a high proportion of their DDT and DDE body burden to their infants.

“Primiparae” women are those with one child, their first; “multiparae” women are those who have delivered more than one child.

Without having read the study, I suggest there are a few key points this research makes:

  1. Claims that DDT has been “banned” from Africa and is not in use, are patently false.
  2. Spraying poisons in homes cannot be considered to have no consequences; poisons in in very small concentrations get into the bodies of the people who live in those homes.
  3. We should not cavalierly dismiss fears of harms to humans from DDT, because it appears that use of even tiny amounts of the stuff exposes our youngest and most vulnerable children.
  4. Beating malaria has no easy, simple formula.

Women, even poor women in malaria-endemic areas, should not have to worry about passing poisonous DDT or its breakdown products to their children, through breastfeeding.  The national Academy of Sciences was right in 1970:  DDT use should be stopped, and work should be hurried to find alternatives to DDT.

How to make a dinosaur: Start with a chicken . . .

July 25, 2011

Dinosaur hunter extraordinaire Jack Horner explained to an audience at TEDS that he always wanted a pet dinosaur . . .

(From a talk recorded March 4 2011.)

Jack Horner may look familiar to you.  Or you may not recognize him without the cowboy hat.  Horner is famous enough in dinosaurphile circles that a character who looked like Horner, down to the red shirt and cowboy hat, was included in the Jurassic Park movies.

This is, in loose form, real science.  It’s the sort of stuff that somehow gets squeezed out of science curricula in middle schools and high schools.  What student will not find it interesting to talk about why we can’t clone dinosaurs from mosquitoes trapped in amber, but how we can regress a chicken to bring out atavistic traits?

Such material may cause apoplexy among some cliques at the Texas State Board of Education — because this reinforces evolution ideas.  Horner says, “We can fix the chicken — because evolution works.”

Science teachers:  Can you find some way to shoehorn this stuff back into your classes?


Still no fireworks at Texas SBOE . . . yet

July 21, 2011

July 21, Austin — The board reconvened at 5:35.  An amendment to the approval of Tech System’s chemistry supplement was quickly passed.  Without any discussion, physics and IPC (“integrated physics and chemistry” — science for kids who will not be interested in science, and for teachers who can’t make them interested — but I digress), approved on raise-of-hand, quick votes — both in under three minutes total.

Biology! Staff notes there are some noted errors contested by publishers; the board again discusses what constitutes an error.  Craig begs for delay to tomorrow, since no one on TEA staff appears to have any biology expertise to rule on whether an error is an error.

Publisher in question is Holt McDougall — the #1 biology textbook publisher, for textbooks in high schools and junior colleges.  Holt asked for a hearing on the errors.  If I understand the discussion, the board is saying they’ll stick with the panel recommendations, since they are doing that for all other publishers. In short, the process is unclear to those who invented the process and those who are ruling on the product.  This would be a good essay from Richard Feynman, wouldn’t it?

Dollars to doughnuts, those members who now claim not to be able to figure out whether errors of biology are errors of biology, will be saying soon that they are competent to rule on key theories of science (evolution).

[Remember to see the immediately previous post, for links to Texas Freedom Network and Texas Observer blogs also covering this process live.]

Oy.  Twenty minutes of discussion on whether to ask a representative from Holt to explain why Holt thinks designated errors are not errors.  Board doesn’t know their own process — are errors noted by a vote of the review panel, or by a simple designation from any panelist without discussion.

Motion to hear from the publisher.  Mavis Knight wants to know why a motion is required, if the SBOE rules say the board can call a publisher any time.  (“And, Texas doesn’t execute innocent people, either.”) Garza discusses issue before the vote.  Debatable motion?  Yes.  “I don’t think we’re going to learn anything new from the publisher.”  (Who said that?)

Knight speaks in favor of hearing, to learn how the publisher got to their conclusion that the designated error is not an error.  Soto agrees.  Ratliff favors the motion, too — “to make sure that what we’re about to approve for the next decade is the best possible material” — and because the board doesn’t know whether the question from the panel represents a consensus or a wild hare.  Clayton — “is [the publisher] also a biologist, and can he address the issue?”  “I wonder if we’re wasting our time listening to a publisher instead of a biologist.”

[Lost some text — sorry]

6:06, motion to listen to publisher fails, 7-7.

Update, after adjournment:  Board voted to approve Holt-McDougall’s supplement on the condition that the publisher change things identified as errors by the review panel.  Board, by voting not to hear the publisher, failed to note that the “errors” are contested.  View of  biologists present is that the board is ordering Holt-McDougall to introduce errors.  Before final approval, can we get the board to come down on accurate science’s side?  This is the quiet erosion of good science I feared.

Board then pulled out three products for discussion, approving the others (biology, remember) on a hand vote.  Products pulled out are Adaptive Curriculum, Learning.com’s Adaptive Curriculum on their platform, and Technical Laboratory Systems’ SciTEX Biology.

Gail Lowe says the objection is the addition of Haeckel’s embryo drawings.  This is an old issue with Texas creationists.  They jumped on the Discovery Institute’s claim that Haeckel’s drawings show evolution, but where evolution doesn’t occur.  (Haeckel fudged drawings, biologists have known for years — but his fudged drawings haven’t been used to make his erroneous point in 50 years . . .).

Publisher steps up and shows photographs that they have agreed to substitute.

Somehow, the creationists fail to notice that what has happened is they are insisting on photographs that show evolution in stead of a drawing.  (Turns out the drawings are not Haeckel’s after all — just line drawings of embryoes).  Creationist Gail Lowe excitedly makes the motion to accept the product with photos instead of line drawings.  (Somewhere a Discovery Institute wizard is having a heart attack.)

Board proceeds to make similar motion for Learning.com’s version of Adaptive Curriculum’s stuff.

6:25 p.m.

Lowe complains of spelling, punctuation and subject-verb agreement issues on the slides for SciTEX Biology.  Motion to insist they be corrected before they make it to classroom.  Discussion . . . (discussion?  discussion?)

The science is right, but the spelling is wrong.  [To this old copy editor, this strikes me as bizarre.]  “In the future we need to appoint at least one member to each panel who is an expert in the English language.”  (missed which guy said that)

Motion to approve, with errors to be fixed, passes.

Item 8, biology supplements, as amended, is approved.

No fight.

Counsel says there must be a formal motion to reject the materials from the ID/Creationist guys.  Motion passes.

I’m a fireworks fan, but missing fireworks in this room is a good deal.

Board adjourned for the evening.  Votes on other issues, and final approval, tomorrow.


No fireworks at Texas SBOE – quiet erosion of science? (Live blogging)

July 21, 2011

July 21, 2011, Austin — Far fewer people than usual signed up to testify on the electronic science book supplements the Texas State Board of Education is considering in lieu of new textbooks (no money for texts from the legislature, you recall).

So, in keeping with Chairman Barbara Cargill’s wishes, testimony concluded at 4:06 p.m. CDT, just six minutes later than scheduled.

Good deal.  The air conditioning in the first floor hearing room still doesn’t work well.

Since 2003, the most visible difference in these hearings is the back wall.  That’s where the electrical outlets are, and so those seats get taken up by publishers, lawyers, lobbyists, and a few bloggers.

These events are being live-blogged by Steven Schafersman from Texas Citizens for Science (at the Texas Observer site), and by the Texas Freedom Network’s blog, Insider.  I’ll add notes below as we progress.

When the board reconvenes at 4:30, the board will take up consideration of the supplemental materials.  If they follow the testimony, there will be a quick vote to approve all of the supplements still standing.

But this may be where the fireworks get lighted.

Most witnesses asked the board to simply approve the supplemental material favored by staff at the Texas Education Agency and by the panels of teachers and experts the board appointed earlier.  Those recommendations excluded the only pro-creationism materials by a small, first-time publishing company.

Andrew Ellington, the biology whiz from the University of Texas, gave another great presentation — limited to two minutes under the new rules.  Most pro-evolution witnesses got no questions.

Josh Rosenau, the out-of-state champion for evolution (from the National Center for Science Education – NCSE, and Sciblogs blogger at Thoughts from Kansas) made the case for hard science.  Walter Bradley, the champion for creationism, didn’t show up.  He sent a substitute to read his testimony, in which he urged rejection of all the proposed materials because they don’t savage Darwin.  He also gave thanks to God for the Texas SBOE.

Schafersman wrote, and you may wish to note:

My friends at Texas Freedom Network (TFN), Ryan Valentine and Dan Quinn, are also live blogging this meeting at TFN Insider. Josh Rosenau of the National Center for Science Education is also here live tweeting at at @JoshRosenau and @NCSE (using hashtag #txtxt). TFN informs me they are also live tweeting at #SBOE. Abby Rapoport of the Texas Observer will also be tweeting about this meeting using #SBOE.

______________

The Board reconvened promptly at 4:30.  After a typical, SBOE-style confused discussion of the process, submissions for science supplements for grades 4, 5, 6 and 7 were quickly approved on a show-of-hands vote.  The room has an electronic voting system which could offer quicker results.  A show-of-hands is folksy and friendly, but leaves a poor record for tracking.  Is this an intentional stab against transparency?

Discussion stalled at 8th grade materials.  Question raised about whether striking a publisher’s materials requires just one objection or a majority vote (should be majority vote — the chair’s description sorta said that).

One publisher disputed two of 132 found errors — staff agreed with the publisher that there was no error.  Chemistry.  Chair Cargill announces that chemistry, physics and IPC curricula for high schools will be considered first — biology last.  (Fireworks then?).

[Much of this discussion carries little significance.  Among the errors officially tallied:  “Judgment” is misspelled.  Gail Lowe makes it clear that she has what she thinks are significant errors identified for one publisher, in the biology materials- Pearson,Technical Laboratory Systems, Chemistry I think.  Fines can be levied for publishers who fail to correct errors.]

This discussion is so much inside baseball that the board takes a recess to figure it out.

It looks like — correct me if I’m wrong — the board is working to take potshots at some publisher’s biology stuff, and kill it.


War on science, war on education: Evolution under fire at Texas education board

July 21, 2011

Ryan at the Texas Freedom Network laid out the stakes:

Just a reminder about what new chairwoman Barbara Cargill — and her five “conservative Christian” allies on the State Board of Education — have in mind for the meeting this week:

I am a little bit concerned in looking at some of these science online supplementary materials. I looked at one of the links and there was a picture of a — a graphic of a human fetus next to a gorilla fetus talking about how they only differ by one amino acid. Therefore, universal common decent. So that is of some concern. And I am not quite sure if we are going to have the votes to overturn that. We will work diligently to rectify and correct some of that. But remember we lost a conservative seat, so we’re down to six.

In this unguarded moment, Cargill drops the double-speak and is honest about her plan for the first meeting over which she will preside as chair  — pressure publishers to censor scientific information from their materials and to insert bogus information questioning evolution. And she knows exactly what her task is: to get the extra votes necessary to accomplish this.

Stay tuned to TFN Insider on Thursday and Friday as we give you a front-row seat at the contentious hearing and board vote.

Live blogging the meeting starting at about 10:00 a.m today at TFN Insider at at Steve Schafersman’s blog, from the Texas Citizens for Science.

“Eat your peas, Gregor”

July 20, 2011

Gregor Mendel was born July 20 in 1822.

Google’s doodle honors the man now generally regarded as the “father of modern genetics.”  The Washington Post blogs note, “Rare is the monk who gets to be celebrated for passing down his genes.”

Oblivious to Mendel’s work and significance, and to much else in the world of knowledge, the Texas State Board of Education debates how to frustrate the teaching of evolution with hearings in Austin tomorrow, and a vote on supplementary materials to texts in biology on Friday, July 22.

Mendel would urge, pray for Texas and the children who will be saddled with the decision of the Texas SBOE.

Look up something about Mendel.  Maybe we could all learn something from him.

Friends of science and evolution: Testify next week in the Texas textbook process?

July 14, 2011

I get important e-mail from the Texas Freedom Network; they’re asking for help next week to fight creationism and other forms of buncombe popular in Texas:

Science and the SBOE: One Week to Go

Next week, the Texas State Board of Education will take a critical vote on science in our public schools. We need people like you to make sure the vote is in favor of sound, well-established science.

Up for board consideration are science instructional materials submitted by a number of publishers and vendors who want their product used in Texas classrooms. Even before the board meets, far-right groups have been hard at work trying to ensure materials approved by the board attack and diminish evolutionary science and include the junk science of “intelligent design”/creationism.

The attacks include one from a little-know firm out of New Mexico, International Databases, which submitted instructional materials rife with creationist propaganda.

It gets worse. Far-right SBOE members last month appointed creationists with questionable scientific credentials to teams tasked with reviewing the materials and making recommendations to the board.

And new board chair Barbara Cargill upped the stakes when in a speech just last week she framed the debate over science as a “spiritual battle.”

The board will hold just ONE public hearing on the science materials. Your participation is crucial.

It is critical that you act now by clicking here to express your interest in testifying before the board on July 21.

Please note: The deadline to sign up to testify is 5 p.m. Monday.

We must insist that the SBOE keep junk science – including “intelligent design”/creationism – out of our children’s classrooms. The board must approve only instructional materials that are accurate, that are in line with sound and well-established science, and that will prepare Texas children to succeed in college and the jobs of the 21st century.

Trying to carve out time here.  Can you help?

Hearings will be most interesting.  Support for the Texas State Board of Education actually comes, often, from the Texas Education Agency (TEA).  TEA this week laid off just under 200 workers, to deal with the 36% budget chopping done to the agency by the Texas Lege.  Word comes this week that curriculum directors at TEA were let go, including the director of science curriculum.

It’s rather like the first 20 weeks of World War II in the Pacific, with the aggressors advancing on almost all fronts against science.  When is our Battle of Midway?

Are you ready to deal with effects of global warming?

July 12, 2011

Why not?  These guys argue that the most rational solution is to get ready to deal with the problems, and stop worrying about the science behind “whether.”

If a global warming debate about certainty and cause only deepens doubt and defensiveness, what kind of debate would create support for action? We saw Hurricane Katrina as an opportunity to shift from the tired debate over cause and prevention to a new discussion about preparedness, thus reframing global warming from certainty to uncertainty and from limits on human activity to greater activity. Regardless of the cause, global warming is here and we need to prepare for it in the same way we prepare for any other imaginable natural disaster, not knowing exactly when or where it will strike. Global Warming Preparedness was created to test the possibility that action on global warming could be taken, not in spite of uncertainty, but because of it. (Breakthrough Institute, Plan for Global Warming Preparedness)

Are they right?

Troops who fought in two wars now protect public against Missouri River flood and nuclear accident

July 10, 2011

Hoax claims died down a bit across the blogosphere, but the Missouri River still floods, and the two Nebraska nuclear power plants on the Missouri still face threats from the flood.

Comes news via the Omaha World-Herald that members of Nebraska’s and Iowa’s Air National Guard — many of them veterans of Iraq or Afghanistan — patrol the levees, helping protect against floods.  Among points of special concern are the nuclear power plants at Fort Calhoun and Cooper.

The military helicopter’s black shadow dances on an engorged Missouri River as the aircraft slowly loops the flood-encircled Fort Calhoun Nuclear Station — the same left-leaning turns the pilot navigated two days prior.

Warrant Officer Boe Searight, 32, with the Nebraska Air National Guard wants the infrared camera mounted under the chopper to record similar flood scenes for levee experts on the ground to compare.

He and his colleague Chief Warrant Officer 2 Eric Schriner also are looking for new signs of trouble for the flooded plant.

“Keep daily eyes on it and see if anything changes,” says Schriner, 31.

Far below, on mosquito-infested riverbanks, two-person crews with the Nebraska National Guard and Iowa National Guard patrol the Omaha and Council Bluffs levees in mud-caked boots.

Members of the Guard are the front-line levee watchers in an operation that clearly has high stakes: Levees protect about 40,000 people from homelessness in the neighboring river cities — as well as the region’s key airport.

The levee watchers are out there right now — three shifts a day, all week, searching for gopher holes, chasing away sightseers who could fall from the levees, and checking for signs of water seepage.

More than 130 men and women with the Nebraska Army and Air National Guard work each day for flood duty, along with 120 from the Iowa Army and Air National Guard.

The idea is to spot trouble early. Levees don’t always give notice before they rupture, but more often than not they do.

If trouble is spotted, steps can be taken to shore up or boost a weakened levee.

Good to know.  Still no nuclear incident along the lines of the hoax report from the Pakistani outlet alleged to be based on a report from a Russian agency — which is also good news — but no cause for abatement of overall concern.

Sometimes safety preparations work.  Kudos to the Air National Guards, to the Nuclear Regulatory Agency, and to the companies who own  the power plants.  May their work continue to pay off in no nuclear incidents.

Idaho Samizdat noted earlier that the bizarre conspiracy theories haven’t borne out as accurate or true in the least:

The flooding situation in Nebraska has been the subject of bizarre conspiracy theories originating in Russia and Pakistan alleging that a meltdown has occurred at Ft. Calhoun and that the government is covering it up.

One U.S. web site, Business Insider, ran with the story as legitimate and set off a huge round of copy cat reports on the Internet.

Reports of a U.S. news blackout are also part of the conspiracy theory even though Nebraska papers such as the Omaha World-Herald and the New York Times have run major stories on measures by the two reactor sites to prevent the flood waters from reaching important infrastructure such as switch yards


Coach the beauty pageant contestants in critical thinking, please

July 10, 2011

Everybody else has to know it, or suffer without it.

Can you tell which of these is the parody?

Is it this one?

Or is it this one?

Stephen Law reports the science geek won the competition — maybe that will be enough to spur other beauty pageant contestants to get hip to reality?

Susana Speier explained what’s going on at Scientific American’s online site:

Last week, self proclaimed “geek,” Miss California, Alyssa Campanella made beauty pageant history…by default. When the interviewer posed a Theory of Evolution question, she was one of only two delegates to use the scientific definition of the word “theory” in her response.

The honey-drenched, colloquial definition that the majority of her competitors clung to was, yes, diplomatic. Miss California, now Miss USA, however, did not aim to please or to appease the 60% of Americans that a 2009 Gallup Poll concluded do not believe in Evolution. Rather than aiming to please or appease an ignorant majority, The future Miss USA delivered a response that supported an empirical evidence based definition of specified phenomena: the scientific definition of the word, “theory.”

Brains is beauty, it seems to me.  We should certainly run our schools as if intelligence and learning are great virtues in themselves.

 

 


Watching the drought roll in at Colorado Bend State Park

July 6, 2011

It took me a couple of tries to figure it out — last week when I told people Kathryn and I were off to Colorado Bend State Park to spend time on the river, several people commented about how much cooler it would be there.

What?  West of Killeen about an hour, ten miles of dusty road outside of Bend, Texas (population 1,637), Colorado Bend is not cooler than Dallas.  It was over 100° F every day we were there, stayed well above 90° most  of the nights.

Kathryn Knowles checking wildflowers, Colorado River, Texas

Kathryn studied wildflowers at a spring at the side of the Colorado River during a break from kayaking; this spring's flow was reduced, but still moist enough to create a near-oasis.

Our well-wishers were geographically confused.  They thought we were headed to the Colorado River in Colorado, not the Colorado River in Texas, which is not the same river at all.  I didn’t bother to check the temperatures in Colorado, but one might be assured that it was cooler along the Colorado River in Colorado than it was along the Colorado River in Texas.

It was a return trip.  We stumbled into the park 16 years ago with the kids, for just an afternoon visit.  The dipping pools  in the canyon fed by Spicewood Springs captivated us.  It took a while to get back, and then the kids were off doing their own thing.

So, just a quick weekend of hiking/camping/kayaking/soaking/stargazing/bird watching/botanical and geological study.   Park officials closed the bat caves to human traffic in hope of keeping White Nose Syndrome from the bats; we didn’t bother to sign up for the crawling cave tour through another.

Ed Darrell at Colorado Bend State Park, Texas

The author, still working to master that Go-Pro camera on the hat -- some spectacular shots, but I don't have the movie software to use it all; you know it's hot when SPF 75 sunscreen is not enough.

What did we see?  Drought has a firm grip on Texas, especially in the Hill Country, especially outside of Dallas.  The Colorado River  is mostly spring fed; many of the springs are dry.  No water significant water flowed through the park while we  were there — kayak put-ins have been reduced to the downriver-most ramp, and the bottom of the boat launch ramp is three feet above water.  Gorman Falls attracts visitors and scientists, but the springs feeding it are about spent this year — just a few trickles came over the cliff usually completely inundated with mineral-laden waters.

Drought produces odd things.  The forest canopy around the park — and through most of the Hill Country we saw — is splattered with the gray wood of dead trees, many of which at least leafed out earlier this spring.  The loss to forests is astonishing.  Deer don’t breed well in droughts; deer around the campsites boldly challenge campers for access to grasses they’d ignore in other seasons.  One ranger said he hadn’t seen more than about three fawns from this past spring, a 75% to 90% reduction in deer young (Eastern White Tail, the little guys).  Raccoons are aggressively seeking food from humans, tearing into tents and challenging campers for food they can smell (lock your food in the car!).  Colorado Bend is famous for songbirds, including the endangered Golden Cheeked Warbler, and the elusive, spectacular painted bunting.  But the most commonly-sighted birds this year are turkey vultures, dining on the young that didn’t make it healthy into the summer and won’t survive until fall.

Warming denialists’ claims of “not so bad a drought” ring out as dangerous, wild delusion.  (By actual measurement, Texas average rainfall the past nine months was 8.5 inches, the driest ever recorded in Texas, shattering the old record drought of 1917).

Great trip.  Kathryn’s menu planning was spectacular.  The old Coleman stove  — a quarter century old, now, with fuel almost that old — performed like a champ even without the maintenance it needs (later this week).  Other than the hot nights, it was stellar.

Stellar.  Yeah.  Stars were grand.  It was New Moon, a happy accident.  A topic for another post, later.  Think, “Iridium.”

So posting was slow over the weekend.  How far out in the Hill Country were we?  Neither one of us could get a bar on our phones.  We were so far out the Verizon Wireless guy was using smoke signals.

Thoreau was right, you know.


PestAway: Exterminator deals with DDT, honestly

June 29, 2011

Here’s a cool breeze:  Pest Away Exterminators in New York explains, patiently, that DDT no longer works against bedbugs, and is otherwise ill-advised in most applications.

Try to find an error in this short post:

DDT

The truth about DDT…

  • It was highly effective when it was first introduced.
  • It nearly wiped out bed bugs in America.
  • It is NO LONGER effective in treating bed bugs.
  • It is more dangerous than people realized.

In 1939, DDT (Dichloro-Diphenyl-Trichloroethane) was introduced as the “miracle pesticide.” It was effectively used in military and civilian arenas to control lice, malaria, mosquitoes and bed bugs. It nearly wiped out all bed bugs in an allegedly “safe” method, but by the 1960’s, bed bugs had built up a resistance and potential immunity to DDT.

In 1962, Rachel Carson wrote Silent Spring, which essentially demonized DDT and helped launch the environmental movement. By 1972, DDT was banned in the USA, but DDT is still used very effectively in other countries to control Malaria. Although there is a public outcry to bring DDT back, it’s very unlikely that it would have any meaningful effect on controlling bed bugs.

Jeff Eisenberg founded the company in 1991, after a career with a large accounting firm.  It appears his training on the importance of accuracy in numbers, and honesty in facing tough situations, carried over to his new business.  Good on him.
