Wall Street Journal, etc: Designer babies. Some say you can order them now.

Friday, February 13th, 2009

The WSJournal‘s Gautam Naik ran yesterday a provocative story under a lively hed: A Baby, Please. Blond. Freckles — Hold the Colic. The news is that a clinic in Los Angeles is offering to do a deep genetic diagnosis of preimplantation embryos and come up with, in essence, bespoke sons and daughters. The story says that there isn’t much evidence the clinic has actually made good on its promise, but also says that’s beside the point. And the point is that in principle such things seem quite plausible and perfectly legal and hence more such pitches are sure to come.

The graphic is easy to understand. Ethical misgivings get fair play in the piece. So do polls showing that, while still a minority, a significant number of fertility clinic and genetic counseling customers say that, beyond vigilance against disease genes, they’d by happy to check the boxes to prefer genes that might bestow height, athletic ability, etc.

Such news seems to be in the air. A search finds a smattering of similar dispatches:

New Scientist: One last toast to Darwin

Friday, February 13th, 2009

Thought this site was done with Darwin Day, eh? Here’s one more from New Scientist‘s Rowan Harper today. It’s a short piece, worth a look, but its highlight is this limerick provided at a Darwin rally by the operators of an enterprise called Darwin Brewery, which has an aptly named libation:

Charles Darwin was deep in reflection
On the fossils within his collection
When you sit down and think
You need a long drink -
Beer is the Natural Selection!

Orange County Register: End of the Rainbow

Friday, February 13th, 2009

The Register‘s science editor Gary Robbins is getting lots of reaction from his readers to a photo one of them sent him and he ran on line. It shows a rainbow running right into the ground – or, actually, into the asphalt of a rainy day road. Some readers, he says, think it was photoshopped. It is remarkable.

The Tracker thinks Robbins, a keen reporter, may have missed a chance in this case to explain some optics. So I’ll take a stab at it.

So, as we all know don’t we?, rainbows are the refracted backscatter of sunlight off raindrops (the actual optics of that, I recall, is very complex). The refraction angles vary with wavelength which in turn provides the nice colorful arc. And, most important to the immediate topic, the bow’s intensity depends on both the brightness of the sun and the number (and sizes?) of raindrops in the appropriate directions. Okay then. In the general sky it usually takes hundreds of yards or even a mile or so worth of raindrops to generate much brightness. So natch one rarely sees a rainbow going all the way to the ground right in front of one. There is just not enough optical action over such a short distance. But one can see such a thing while standing in the garden sprinkler’s spray on a bright day. There are lots of water drops from a nozzle like that. If it ever rains that hard, stay out of the creekbed. Well! A tire’s spray can accomplish the same thing. So, the rainbow above, visible between the photographer and the sky and mountains, would have faded out as normal at its end except for one thing. It gets a boost from the wheel spray right at its bottom. I think, but am not sure, that a harmonic secondary rainbow is above the Mini and that it too brightens at its terminus.

All that longwindedness can’t change the fact. That’s a cool picture. (…god, I hope I’m right about the off the cuff explanation). And while Robbins’s item ran a week ago or so, today’s a good day for it – to counter the bad mojo of a Friday the 13th.

San Jose Mercury News: Everything you may have just read about Pelosi’s Mouse is wrong

Friday, February 13th, 2009

The Mercury News‘s Paul Rogers indulged in some old-fashioned, grown-up debunking this week. It seems that deep in the attacks and counter-attacks over the economic resuscitation legislation is the allegation of a porky little item assigning $30 million to save a tiny endangered rodent native to San Francisco Bay’s salt marshes.

So Rogers looked into it. He traces it to a CNN assertion, and that in turn to a GOP lawmaker’s press release. He further tracks the various numbers and other such things associated with it. Looks like CNN, or somebody on its staff who might have looked into the facts, whiffed on all counts. In the meantime, he writes, on the internet it has become instant urban legend. Kudos.

Lots of Genomic Ink: Genome(s) of common cold virus ; and of Neanderthal (one, partial)

Friday, February 13th, 2009

The Tracker rather likes the headline over the LATimes story by Mary Engel today: “Rhinovirus strains’ genome decoded: cold cure-all is unlikely.” No false hopes there for an exit from the most common sniffles. And if the hygiene theory of immune system toughness is right, we’re probably better off. The fully charted genomes have, as one suspects every serious viral contagion specialist could have told you they would, such diversity among their 15 types that they offer few common avenues to treatment. Or, as Engel advises, don’t toss out the chicken soup yet. It’s rather difficult however to avoid another cliche (which Engel does, but the Tracker won’t): the achievement is nothing to sneeze at. Can’t hurt, new research avenues will open, etc. Researchers at the Univ. of Maryland School of Medicine and with the J. Craig Venter Institute led the study and have it this week in the AAAS’s Science magazine.

A second and more broadly intellectually satisfying – if practically near-useless – genome is in the news so we’ll run two lists of stories a bit farther below. It belongs to our distant yet close kin, the Neanderthal. The McClatchy Newspaper chain’s Robert S. Boyd tempts readers in with a little vignette starting “It was an unfortunate accident, but a lucky break for modern science. About 38,000 years ago , a Neanderthal man living in what’s now Croatia broke his left arm…..” At least one other story says it was a woman. Either way, the compensating overgrowth of bone in his/her right arm created enough tissue mass to preserve a smidgen of DNA, it appears. That, combined with smaller samples from other specimens, made the work possible.

The news is that Svante Pääbo of the Max Planck Inst. for Evolutionary Anthropology in Leipzig and a multinational team presented their draft genome at the AAAS meeting in Chicago, an event accompanied by a AAAS press release issued also in Croation, German, Russian, and Spanish. Plus, press conferences in Chicago and Leipzig. In truth, this is lots of ink for a progress report on a project given heavy, previous coverage. But the two genomes do have an odd resonance. These Homo Neanderthalensis folks could as appropriately be called Homo rhinohumongous. They had big noses. And no Kleenex. Maybe human rhinoviruses evolved some of their biodiversity in their magnificent ice-age schnozzes? Nobody covers that obvious angle!   Below are further samplings of coverage.

(UPDATED*) Lots of Ink: Traffic accident in space: A derelict Russian comsat and a working US one in smash up. Smithereens spreading fast.

Thursday, February 12th, 2009

It happened over Siberia, so maybe the Russians will clean it up? Probably not. This is too big a mess to clean up. Yesterday Iridium Satellite LLC, the operator of the big fleet of relay stations for satellite telephones, said it had lost one of its birds. It ran into a non-operating Russian Cosmos-2251 military satellite, a big one launched back in 1993. Iridium’s release says it wasn’t its fault. Well, who’s then? Hmmm. Maybe the whole space age’s.

It surely is a bigger debris cloud, and hazard, than that feckless bit of space show-offmanship a few years ago when China deliberately smashed one of its own satellites to bits. The two satellites are in fairly low orbit, about 500 miles, not way up there at geosynchronous altitude. The bad news is that the junk offers some, very slight risk to the International Space Station. The good is that, at such low level, at least the bits ought to reenter the atmosphere before too many years have passed. In the meantime, mankind’s pollution is reaching a new high.

For a look at pretty good breaking news TV reporting, the RussiaToday network, with a rather Brit-sounding anchor and a correspondent, Anastasia Churkina, describe it in great detail. Nice job (One wonders how much CNN misses its erstwhile, laid-off space whiz Miles O’Brien about now).

*UPDATE: Popular Mechanics turned out a passel of good analysis and accounts in a hurry, led by Glenn H. Reynolds on the status of space law regarding space junk, and it links to stunning, archived modeling of what happened to the debris after China bonked its own satellite just to show that it could.

As days go by, more deeply reported stories on the difficulties of crafting and executing a sensible policy against such things will, presumably, emerge.

Not much attention: A high pressure super balloon over Antarctica gathers some data, sets a record

Thursday, February 12th, 2009

Correction: For several hours this post attributed one of the stories below to the wrong pub, Pop. Science rather than the actual Pop. Mechanics. 

________________

Only a couple of specialty outlets are carrying what seems to be entertaining and engaging and stimulating news of scientific and engineering adventurism. A gigantic NASA test balloon on Feb. 7  set a record for heavy load-carrying endurance in the stratosphere, floating high over Antarctica for 42 days (and counting). Slung beneath it is a 1,500 pound test payload.

The deal with this one is that it doesn’t change its volume (and hence altitude) from day to night as sunlight cyclically heats its helium floatant. (Actually floatant is goop one puts on fluffy lures for dry fly fishing so they’ll sit high on the water’s surface but it fits here, sort of.) Its material is not stretchy and its helium is at sufficiently high pressure to keep it fully plumped even when very, very cold. It also is relatively impervious to leakage by the tiny atoms of helium. The previous record was set by a balloon that the same program launched. One reason so few outlets paid attention to this record-breaker is here posited: No sign of a press release to mark the record-setting itself, although in Grist is a release on the launch, from the team at New Mexico State University that conducts most of NASA’s high altitude ballooning.

As this is an existing and well-traveled balloon design, the real news will come with launch of a new iteration that will be bigger and should stay in the air for 100 days at a stretch or, more properly given the engineering principle, the non-stretch.

The flood crests: Happy Birthday Mr. Darwin

Thursday, February 12th, 2009

If one shouts and orates until hoarse to herald the approaching great day, there may be nothing left to say upon its arrival. No such luck with the Darwin200th celebration today. Even Google put up on its search page a new bicentennial logo featuring finches and Post Office Bay on Isla Floreana where the man went ashore.

One must say something about some of the many accounts discovered mainly by that very Google device – a winner of another kind of survival of the fittest. In those stories many writers, even some scientists, credit Mr. Darwin rather over broadly with, in effect, discovering evolution and forever therefore changing biology and much of science. He did the latter, not so much the former. The Tracker’s no expert, but does know that Darwin’s own grandfather Erasmus was among several naturalists of that general time who felt that some means of common descent best explains nature’s living diversity. Rather, Darwin’s more towering achievement was to provide an explanation for speciation’s instigation, via natural selection, and to back it up with voluminous observation. Alfred Lord Wallace was hot on his trail but Darwin had much bigger caliber artillery. He turned an attractive hypothesis into a robust, testable, and data-rich theory that is today so well documented as to be roughly on par in the fact department as are the atomic weights of hydrogen isotopes. It’s fine to see such attention to the man in any case. Thank goodness too.

Here’s a sampling, with emphasis on sampling, of the pieces out today, with a little catch-up on some of the handsomer packages.

Newspaper Editorials, Op-Eds :

  • St. Louis Dispatch: The man who changed the world ;
  • Wash. Post – Rick Weiss : Something Darwin Didn’t Know ; He says Darwin actually “punted” on religious questions. One quibble with this: it was likely the reading of Charles Lyell’s Principles of Geology, more than his own shell and rock collecting, that opened Darwin’s eyes to the immensity of geological time.
  • Wash. Post – Susan JacobyDarwin the Disturber ;
  • Philadelphia Inquirer – Steven Conn : The twin revolutions of Lincoln and Darwin ; which among other things points out, as has many, that Darwin’s revulsion at slavery equalled and perhaps even surpassed that of the great emancipator. He should have thrown in St. Valentine’s Day in two days and the real revolution that drives evolution: sex, romantic and otherwise. Wotta weekend.
  • NYTimes – Verlyn Klinkenborg: The Ongoing Force of His Unconventional Idea ;

Big Packages :

Broadcasts:

  • Scientific American podcast site: Readings, and bits by Richard Milner from his one-man Darwin state reincarnation, and more.
  • BBC – David Shukman (print and video clips) : A visit to the Galapagos and the damage they face from tourism.
  • KQED Quest (San Francisco) Chasing Beetles, Finding Darwin : excellent local production. Lots of Darwin talk interspersed with traipsing along with one local scientist as he hunts a specific beetle species that facts peculiar to the region, plus overarching evolutionary theory, imply must exist. Producer Gabriela Quirós.
  • Nature podcast – Actor Paul Bettany describes playing Darwin for a new movie, “Creation.”

Anchorage Daily News: The killer whales of Prince William Sound. 20 years after the big oil spill, one group looks doomed.

Wednesday, February 11th, 2009

The remnant AT1 population of orcas is, it appears, living a quiet and unproductive life, dwindling toward oblivion long after the Exxon Valdez oil spill hit some of its members hard. The Daily News‘s Kyle Hopkins has a finely balanced story on these oversized dolphins and on the insights they offer into the ecological damage that might still be apparent from the accident. The Tracker is a skeptic by nature that one-time and infrequent blows such as oil spills, or volcanic eruptions or landslides for that matter, are any great shakes in the larger world of environmental degradation. But this story makes one think. Here is a somewhat genetically distinct group that, while in trouble in the first place, may be finally going over a brink. And the oil spill is a plausible, proximate cause.

Hopkins got the story at a conference in Alaska. He does it long, and with many sources. He, like many Alaskans, is not inclined to be friendly to Exxon. He introduces its take on things with a somewhat snarky clause: “If you ask Exxon, local animals are all on the road to recovery.” But he also includes data suggesting that most of the wildlife is doing pretty well now. The killer whales are described in great detail, along with reasons that while they weren’t thriving beforehand, things got much worse with the spill. The story notes that another, larger population of orcas in the sound did take a hit but seems to have largely recovered.

The pic is part of a much larger graphic accompanying the story.  A second graphic looks at the lingering impact, or vanished impacts, on selected other species.

NPR: How money to study neurons is part of a jobs stimulus package

Wednesday, February 11th, 2009

Yesterday the Tracker watched a television biz pundit, eyes wide and nostrils flared, asking loudly how in the world a provision for honeybee research in the stimulus package now in conference committee can possibly be anything but pork. Well, no earmarks is the answer, but that wasn’t the raver’s point. I thought immediately that if we don’t solve our pollinator problem and quick, California’s job-generating almond industry is in trouble. Mostly however it just illustrated how goofy-sounding titles on scientific research is easy pickins for cheap shot artists among our elected officials and various editorialists looking for examples of wasted tax dollars.

All this as preamble to a salute to NPR‘s Richard Harris for connecting the dots between jobs and science grants. Its hed is “Scientists Hope Stimulus Will Give Jolt To Research.”  The story hasn’t yet broadcast, so only his prose is to be found (he’s good at that too. He was a newspaperman before he was a radio newsman). Harris went and found a few professors and lab leaders who explain that when they get money, it goes immediately into payroll for doing the research. He gets the stats on research proposals that have plenty of merit, but outnumber the grants available. And, one might add, grad students and post-docs – being peons – work crazy long hours for not much dough, so the productivity and employee-per-dollar via research grants is high. More important, such reporting as Harris’s might, just a tad, relax that instinct on The Hill to lambaste academic work as somehow not real work (and not to say that some scientific research is pretty hard to connect to anything economically immediately useful).

Reuters, Otago Daily Times: A New Zealand woman’s bull kelp study and climate change’s deeper history

Wednesday, February 11th, 2009

A Reuters story today leads to a tidy bit of science writing in a small newspaper in New Zealand. The Reuters piece is just out, and it has a clear news hook. The agency’s climate change correspondent in Asia, David Fogarty, reports from Singapore that a University of  Otago (NZ) study of bull kelp sea weed finds a sudden plunge in its genetic diversity as one nears Antarctica. The conclusion from the latitude of the shift is that, in the last ice age, winter sea ice extended much farther north than now and scoured away any incipient kelp forests around islands that today are full of them. The study is in the Proceedings of the Nat’l Academy of Sciences. The Reuters account is a satisfying story of some new data and their impacts on conventional thinking. It is therefore intellectually stimulating. But as it’s reported by telephone and press release, etc., it also is a bit short on color.

But nosing around for anybody else who covered it turns up a charming little profile, with no news hook at all except that a grad. student in her wetsuit has a yen for bull kelp and for climate studies, plus has a willingness to get into some very rough water to sample it. She’s the prime author cited in the Reuters story. Between the two one gets the news, and the young researcher behind the news. The Otago Times‘s Bruce Munro had this one last July as part of what appears to be a “Your town” regular feature for the newspaper.

Lots of Ink: For the birds, bad news on the rise.

Wednesday, February 11th, 2009

An Audubon study showing a northward movement of the ranges of North American birds, accompanied by evidence some may not survive their effort to follow their suddenly migratory habitats, triggered a wave of stories yesterday and today. Birds are a singularly noticeable impact of climate change on wild and urban areas alike and thus a topic tempting to reporters. Hence, many references to robin redbreast. The bird society’s annual Christmas Bird Count, say Audubon analysts, reveals a pattern of movement with “an undeniable link to the changing climate.”
The general observation is not new. What Audubon provides is a pile of numbers and names of numerous specific species.

Somewhat confusing the Audubon news effort, its California chapter chose the same day to release a more narrowly targeted report (in Grist below) on climate change’s projected impacts on that state’s birds. But many reporters, on their own, dug into the big report to find out what it means for their own readership. This one gets a lot of localization by the unusual number of smaller papers that jumped on the story.
