The Dumbest Question You Can Ask A Scientist

From and published in “How to Fly a Horse“, the dumbest question you can ask a scientist.

The dumbest question you can ask a scientist — or any other creator, inventor, or discoverer — about his or her work is,

“What’s the economic value?”

One reason: In 1888, after eight years of experiments, Heinrich Hertz created electromagnetic waves in air. He died six years later, believing his work was theoretical and without practical value. (In an often repeated, probably apocryphal story, Hertz tells students the waves have “no use whatsoever.”) Then, after his death, inventors found Hertz’s waves could be used to communicate, renamed them “radio waves,” and started a revolution of immeasurable consequence. First came wireless telegraph, then voice broadcasting, two-way radio, radio telescopes, radar, television, microwave ovens, radio satellites, cellphones, radio-frequency identification, GPS, UAVs, Bluetooth, Wi-Fi and, now, the Internet of Things — Hertz’s children all.

Another reason: In 1924, Gordon Dobson, working in his backyard in England, invented a device for measuring atmospheric ozone. In 1976, after deploying 100 of them globally, he died. His work helped save the world. Scientists discovered that CFCs, chemicals used in refrigerators and aerosols, could destroy ozone, exposing us to deadly radiation. The chemical company DuPont, which made billions of dollars selling CFCs, demanded “reputable evidence.” NASA satellites found nothing, but one of Dobson’s devices, in Antarctica since 1957, detected a massive ozone hole. CFC production stopped. Now the hole, once larger than North America plus China, will be gone by 2050.

Why does this matter? Because the dumbest question holds us back. In 2009, physicist David Kaplan gave a lecture on the Higgs boson. An audience member asked,

“What do we gain? What’s the economic return? How do you justify all this?”

Kaplan’s good-natured response appears in the movie Particle Fever:

“I have no idea.”

(Then he mentioned radio.)

The question must be especially painful for American physicists like Kaplan. Scientists discovered the Higgs boson — or something almost exactly like it — using Europe’s Large Hadron Collider. Members of Congress killed the American equivalent, the Superconducting Super Collider, in favor of what one, Don Ritter, called,

“making things people want to buy.”

Kaplan’s audience member was interested enough to show up at the lecture, and Ritter is an MIT alumnus who branded himself “the scientist-congressman,” yet both make the mistake at the heart of the dumbest question: confusing unknowable value with no value. History shows that basic science brings the greatest economic value of all — Hertz and Dobson are two of many examples.

Why? First, because of what economics is. Science begets technology, which begets goods, which beget value. Science is the principal source of value in modern economies. Second, because economies are chaotic, most of the consequences of any particular technology are unpredictable. An example: The watermill led to the automatic loom, which led to general literacy.

Add in the fact that the point of basic science is to know what’s unknown, and we see that the dumbest question requests the unknowable value of the unknowable consequences of an unknown thing. Note that only two of these are “unknowable.” The third, the “thing,” is only “unknown.” And the unknown, not the unknowable, is what should guide basic science. Kaplan ended his answer by saying,

“Basic science needs to occur at a level where you are not asking what is the economic gain, you are asking what do we not know? And where can we make progress?”

The work of basic scientists like Hertz, Dobson, and Kaplan can only be driven by curiosity, not purpose. What is the value of a particular curiosity? There is no way to know in advance. Discovery is curiosity’s product; everything else, including immeasurable economic value, follows. We cannot know the worth of something we have not yet discovered. The joy is the rainbow, not the hope of gold at the rainbow’s end.

Knocking Out Melanoma: Does This Triple Combo Have What It Takes?


NIH Director's Blog

3-Way Knockout of MelanomaIt would be great if we could knock out cancer with a single punch. But the more we learn about cancer’s molecular complexities and the immune system’s response to tumors, the more it appears that we may need a precise combination of blows to defeat a patient’s cancer permanently, with no need for a later rematch. One cancer that provides us with a ringside seat on the powerful potential—and tough challenges—of targeted combination therapy is melanoma, especially the approximately 50% of advanced tumors with a specific “driver” mutation in the BRAF gene [1].

Drugs that target cells carrying BRAF mutations initially provided great hope for melanoma, with many reports of dramatic shrinkage of tumors in patients with advanced disease.  But almost invariably, the disease recurred and was no longer responsive to those same drugs.  A few years ago, researchers thought they’d come up with a solid combination to fight BRAF-

BMC Mass Retractions #Scandal #WTF

We’ve talked about retractions and fraud in the past (and the role that peer review has in these cases), but this is extreme.  From The Scientist:

Fake peer review has claimed more victims from the scientific literature, with open-access publisher BioMed Central (BMC) retracting dozens of papers that it began investigating after editors had noticed inconsistencies regarding reviewers. BMC retracted 43 papers in total yesterday (March 26), according to Retraction Watch.

The retracted papers were all originally published this year and were spread over at least 13 BMC journals, with 15 studies having been published in the European Journal of Medical Research. Theretraction notices published by BMC all read similarly. The papers were retracted “because the peer-review process was inappropriately influenced and compromised,” according to the notices.  “As a result, the scientific integrity of the article cannot be guaranteed. A systematic and detailed investigation suggests that a third party was involved in supplying fabricated details of potential peer reviewers for a large number of manuscripts submitted to different journals.”

BMC launched an investigation of around 50 papers published in its titles last November when journal editors noticed suspicious errors, such as incorrect e-mail addresses or misspelled names for reviewers, during final checks on the manuscripts.

Such third-party peer review outfits have sunk other manuscripts recently, with publishing giant Elsevier retracting 16 studies for fake peer review last December and dozens more retractions at a variety of journals.

Specifics are spare as yet on the third-party organization that triggered this latest slew of BMC retractions, but yesterday (March 26) on the publisher’s blog, senior editor of research integrity Elizabeth Moylan wrote: “Some of the manipulations appear to have been conducted by third-party agencies offering language-editing and submission assistance to authors. It is unclear whether the authors of the manuscripts involved were aware that the agencies were proposing fabricated reviewers on their behalf or whether authors proposed fabricated names directly themselves.”

An unnamed BMC representative told Retraction Watch that the publisher did know more about the shadowy third party, but that it wasn’t yet making some details public. “We’ve been told some things in confidence that we’re not reporting on our blog, and the reason we’re not is we don’t have enough evidence to point fingers,” the representative said. “What we’ve done all along is point out the patterns that we have noticed, and we’ve talked to other publishers and we’ve talked to [the Committee on Publishing Ethics] to make sure that people know how we’re stopping them.”

Explainer: CRISPR technology brings precise genetic editing – and raises ethical questions

Shouguang Jin, University of Florida

A group of leading biologists earlier this month called for a halt to the use of a powerful new gene editing technique on humans. Known by the acronym CRISPR, the method allows precise editing of genes for targeted traits, which can be passed down to future generations.

With this explainer, we’ll look at where this technique came from, its potential and some of the issues it raises.

Surgical precision

CRISPR stands for clustered regularly interspaced short palindromic repeats, which is the name for a natural defense system that bacteria use to fend off harmful infections.

Bacteria are infected by other microorganisms, called bacteriophages, or phages. The intricate details of the mechanism were elucidated around 2010 by two research groups led by Dr Doudna of the University of California Berkeley and Dr Charpentier of Umeå University in Sweden.

The CRISPR system recognizes specific patterns of DNA from the foreign invaders and decapacitates them by cutting the invader’s DNA into pieces. The way that the bacteria target specific DNA and cleave it gave scientists a hint of its potential in other applications.

In 2013, two research groups, one lead by Dr Zhang of Massachusetts of Institute of Technology and the other by Dr Church of Harvard University, successfully modified this basic mechanism and turned it into a powerful tool that can now cut human genomic DNA at any desired location.

The ability to cut DNA or genes at specific locations is the basic requirement to modify the genome structure. Changes can be made in the DNA around the cleavage site which alter the biological features of the resulting cells or organisms. It is the equivalent of a surgical laser knife, which allows a surgeon to cut out precisely defective body parts and replace them with new or repaired ones.

Tool for gene discovery

Scientists have long sought after this sort of genome editing tools for living cells. Two other technologies, called zinc-finger nucleases and TALEN (transcription activator-like effector nuclease) are available to achieve the same result. However, the CRISPR technology is much easier to generate and manipulate. This means that most biological research laboratories can carry out the CRISPR experiments.

As a result, CRISPR technology has been quickly adopted by scientists all over the world and put it into various tests. It has been demonstrated to be effective in genome editing of most experimental organisms, including cells derived from insects, plants, fish, mice, monkeys and humans.

Such broad successes in a short period of time imply we’ve arrived at a new genome editing era, promising fast-paced development in biomedical research that will bring about new therapeutic treatments for various human diseases.

The CRISPR technology offers a novel tool for scientists to address some of the most fundamental questions that were difficult, if not impossible, to address before.

For instance, the whole human genomic DNA sequence had been deciphered many years ago, but the majority of information embedded on the DNA fragments are largely unknown. Now, the CRISPR technology is enabling scientists to study those gene functions. By eliminating or replacing specific DNA fragments and observing the consequences in the resulting cells, we can now link particular DNA fragments to their biological functions.

Recently, cells and even whole animals with desired genome alterations have successfully been generated using the CRISPR technology. This has proven highly valuable in various biomedical research studies, such as understanding the cause and effect relationship between specific DNA changes and human diseases. Studying DNA in this way also sheds light on the mechanisms underlying how diseases develop and provides insights for developing new drugs that eliminate specific disease symptoms.

With such profound implications in medical sciences, many biotech and pharmaceutical companies have now licensed the CRISPR technology to develop commercial products.

For example, a biotech company, Editas Medicine, was founded in 2013 with the specific goal of creating treatments for hereditary human diseases employing the CRISPR technology.

However, products derived from the use of CRISPR technology are yet to hit the market with FDA approval.

Call for ethical guidelines

With the CRISPR technology, scientists can now alter the genome composition of whole organisms, including humans, through manipulating reproductive cells and fertilized eggs or embryos. Those particular genetic traits are then passed down through generations. This brings hope to cure genetic defects that cause various hereditary human diseases, such as cystic fibrosis, haemophilia, sickle-cell anemia, Down syndrome and so on.

Unlike the current approaches of gene therapy which temporarily fix defective cells or organs through the introduction of corrected or functional genes, the CRISPR technology promises to correct the defect in the reproductive cells, producing progenies that are free of the defective gene. In other words, it can eliminate the root causes of hereditary human diseases.

In theory,then, hereditary features that people consider advantageous, such as higher intelligence, better body appearance and longevity, can be introduced into an individual’s genome through CRISPR mediated reproductive cell modifications as well.

However, scientists do not yet fully understand all the possible side effects of editing human genomes. It is also the case, that there is no clear law to regulate such attempts.

That’s why groups of prominent scientists in the field have recently initiated calls for ethical guidelines for doing such modifications of reproductive cells. The fear being that uncontrolled practice might bring about unforeseen disastrous outcomes in long run.

The guidelines call for a strong discouragement of any attempts at genome modification of reproductive cells for clinical application in humans, until the social, environmental, and ethical implications of such operations are broadly discussed among scientific and governmental organizations.

There is no doubt that the exciting and revolutionary CRISPR technology, under the guidance of carefully drafted and broadly accepted rules, will serve well for the well-being of human kind.

Anti-Science Quotable: Ted Cruz – climate change deniers are heretics like Galileo…. WTF? #science

I’m a big believer that we should follow the science and follow the evidence. If you look at global warming alarmists, they don’t like to look at the actual facts and the data. The satellite data demonstrate that there has been no significant warming whatsoever for 17 years.

I am the child of two mathematicians and scientists. I believe in following evidence and data. On the global warming alarmists, anyone who actually points to the evidence that disproves their apocalyptical claims, they don’t engage in reasoned debate. What do they do? They scream, ‘You’re a denier!’ They brand you a heretic.

Today the global warming alarmists are the equivalent of the flat-earthers. You know it used to be: ‘It is accepted scientific wisdom the Earth is flat.’ And this heretic named Galileo was branded a denier.

Potential Presidential candidate Ted Cruz

While I also believe in following evidence and data, we probably disagree on its interpretation. Cruz doesn’t seem to notice that the logic of comparing himself to Galileo is back-asswards, not unlike his views on most issues.
