Better Wheat Is “Mired in Excessive, Expensive and Unscientific Regulation”

(p. A19) Monsanto recently said that it had made significant progress in the development of herbicide-tolerant wheat. It will enable farmers to use more environmentally benign herbicides and could be ready for commercial use in the next few years. But the federal government must first approve it, a process that has become mired in excessive, expensive and unscientific regulation that discriminates against this kind of genetic engineering.
The scientific consensus is that existing genetically engineered crops are as safe as the non-genetically engineered hybrid plants that are a mainstay of our diet.
. . .
Much of the nation’s wheat crop comes from a section of the central plains that sits atop the Ogallala Aquifer, which is rapidly being depleted.
. . .
New crop varieties that grow under conditions of low moisture or temporary drought could increase yields and lengthen the time farmland is productive. Varieties that grow with lower-quality water have also been developed.
. . .
Given the importance of wheat and the confluence of tightening water supplies, drought, a growing world population and competition from other crops, we need to regain the lost momentum. To do that, we need to acquire more technological ingenuity and to end unscientific, excessive and discriminatory government regulation.

Francis Collins, head of the NIH, discusses a favorite book of 2013:

(p. C6) Taking risks is part of genius, and genius is not immune to bloopers. Mario Livio’s “Brilliant Blunders” leads us through the circumstances that surrounded famous gaffes.   . . .   Mr. Livio helps us see that such spectacular errors are opportunities rather than setbacks. There’s a lesson for young scientists here. Boldly attacking problems of fundamental significance can have more impact than pursuing precise solutions to minor questions–even if there are a few bungles along the way.

Would Science Progress Faster If It Were Less Academic and More Entrepreneurial?

(p. D5) There is Big Science, defined as science that gets the big bucks. There is tried and true science, which, from an adventurous dissident’s point of view, is boldly going where others have gone before but extending the prevailing knowledge by a couple of decimal places (a safe approach for dissertation writers and grant seekers).

Then there is bootstrap science, personified by Gene Shinn, who retired in 2006 after 31 years with the United States Geological Survey and 15 years with a research arm of the Shell Oil Company.
. . .
Without a Ph.D. and often without much financing, Mr. Shinn published more than 120 peer-reviewed papers that helped change many experts’ views on subjects like how coral reefs expand and the underwater formation of limestone. Some of his papers, at odds with established scientific views, were initially rejected, only to be seen later as visionary.
His bootstrap ingredients included boundless curiosity, big ideas — “gee-whiz science,” he calls it — persistence, a sure hand at underwater demolition (dynamite was comparatively easy to come by in those remarkably innocent days) and versatility at improvising core-sampling equipment on tight budgets. The ability to enlist the talents of other scientists, many with doctorates, who shared his love of hands-on field work and his impatience with official rules and permits added to the mix.

Big Island of Hawaii Bans G.M.O.s Despite Papaya Saved from Disease

IlaganGreggorDefenderOfGMOs2014-01-19.jpg “Greggor Ilagan initially thought a ban on genetically modified organisms was a good idea.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. 1) KONA, Hawaii — From the moment the bill to ban genetically engineered crops on the island of Hawaii was introduced in May 2013, it garnered more vocal support than any the County Council here had ever considered, even the perennially popular bids to decriminalize marijuana.

Public hearings were dominated by recitations of the ills often attributed to genetically modified organisms, or G.M.O.s: cancer in rats, a rise in childhood allergies, out-of-control superweeds, genetic contamination, overuse of pesticides, the disappearance of butterflies and bees.
Like some others on the nine-member Council, Greggor Ilagan was not even sure at the outset of the debate exactly what genetically modified organisms were: living things whose DNA has been altered, often with the addition of a gene from a distant species, to produce a desired trait. But he could see why almost all of his colleagues had been persuaded of the virtue of turning the island into what the bill’s proponents called a “G.M.O.-free oasis.”
“You just type ‘G.M.O.’ and everything you see is negative,” he told his staff. Opposing the ban also seemed likely to ruin anyone’s re-election prospects.
Yet doubts nagged at the councilman, who was serving his first two-year term. The island’s papaya farmers said that an engineered variety had saved their fruit from a devastating disease. A study reporting that a diet of G.M.O. corn caused tumors in rats, mentioned often by the ban’s supporters, turned out to have been thoroughly debunked.
And University of Hawaii biologists urged the Council to consider the global scientific consensus, which holds that existing genetically engineered crops are no riskier than others, and have provided some tangible benefits.
“Are we going to just ignore them?” Mr. Ilagan wondered.
Urged on by Margaret Wille, the ban’s sponsor, who spoke passionately of the need to “act before it’s too late,” the Council declined to form a task force to look into such questions before its November vote. But Mr. Ilagan, 27, sought answers on his own. In the process, he found himself, like so many public and business leaders worldwide, wrestling with a subject in which popular beliefs often do not reflect scientific evidence.
. . .
(p. 19) Ms. Wille urged a vote for the ban. “To do otherwise,” she said, “would be to ignore the cries from round the world and on the mainland.”
“Mr. Ilagan?” the Council member leading the meeting asked when it came time for the final vote.
“No,” he replied.
The ban was approved, 6 to 3.
The mayor signed the bill on Dec. 5.

Global Warming Might Help Mangrove Forests Thrive in Florida

MangroveForest2014-01-19.jpg “Mangrove forests, like in the Everglades, serve as spawning grounds and nurseries for fish and as habitat for a wide array of organisms. But salt marshes are also ecologically valuable.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A14) Much of the Florida shoreline was once too cold for the tropical trees called mangroves, but the plants are now spreading northward at a rapid clip, scientists reported Monday [December 30, 2013]. That finding is the latest indication that global warming, though still in its early stages, is already leading to ecological changes so large they can be seen from space.
. . .
The mangrove forests that fringe shorelines in the tropics are among the earth’s environmental treasures, serving as spawning grounds and nurseries for fish and as habitat for a wide array of organisms. Yet in many places, mangroves are critically endangered by shoreline development and other human activities.
So a climatic change that allows mangroves to thrive in new areas might well be seen as a happy development.
. . .
For years, scientists working in Florida had been noticing that mangroves seemed to be creeping northward along the coast. The new study is the first to offer a precise quantification of the change, using imagery from a satellite called Landsat, and to link it to shifts in the climate.
Patrick Gillespie, a spokesman for Florida’s Department of Environmental Protection, offered no specific comment on the new paper. By email, he said the agency had indeed “seen an increase in mangrove habitats to the north and inward along the Atlantic coast. It’s difficult to determine whether this is good or bad for the ecosystem because it’s happened over a relatively short period (p. A16) of time and may be a result of many factors.”

Organic and Kosher Chicken Have as Much Antibiotic-Resistant Bacteria as Regular Chicken

(p. D3) . . . after a trip to Israel for his sister’s bat mitzvah, Jack Millman came back to New York wondering whether the higher costs of kosher foods were justified.
“Most consumers perceive of kosher foods as being healthier or cleaner or somehow more valuable than conventional foods, and I was interested in whether they were in fact getting what they were paying for,” said Mr. Millman, 18 and a senior at the Horace Mann School in New York City.
That question started him on a yearlong research project to compare the prevalence of antibiotic-resistant E. coli bacteria on four types of chickens: those raised conventionally; organically; without antibiotics, and those slaughtered under kosher rules. “Every other week for 10 weeks, I would go and spend the entire Saturday buying chicken,” he said. “We had it specifically mapped out, and we would buy it and put it on ice in industrial-strength coolers given to us by the lab, and ship it out.”
All told, Mr. Millman and his mother, Ann Marks, gathered 213 samples of chicken drumsticks from supermarkets, butcher shops and specialty stores in the New York area.
Now they and several scientists have published a study based on the project in the journal F1000 Research. The results were surprising.
Kosher chicken samples that tested positive for antibiotic-resistant E. coli had nearly twice as much of the bacteria as the samples from conventionally raised birds did. And even the samples from organically raised chickens and those raised without antibiotics did not significantly differ from the conventional ones.

“Pretty Cool” Cochlear Implant: “It Helps Me Hear”

CochlearImplant2013-11-15.jpg “The cochlear implant.” Source of caption and photo: online version of the WSJ commentary quoted and cited below.

(p. A15) . . . , three pioneering researchers– Graeme Clark, Ingeborg Hochmair and Blake Wilson –shared the prestigious Lasker-DeBakey Award for Clinical Medical Research for their work in developing the [cochlear] implant. . . . The award citation says the devices have “for the first time, substantially restored a human sense with medical intervention” and directly transformed the lives of hundreds of thousands.
I’ve seen this up close. My 10-year-old son, Alex, is one of the 320,000 people with a cochlear implant.
, , ,
“What’s that thing on your head?” I heard a new friend ask Alex recently.
“It helps me hear,” he replied, then added: “I think it’s pretty cool.”
“If you took it off, would you hear me?” she asked.
“Nope,” he said. “I’m deaf.”
“Cool,” she agreed. Then they talked about something else.
Moments like that make me deeply grateful for the technology that allows Alex to have such a conversation, but also for the hard-won aplomb that lets him do it so matter-of-factly.

Hubel and Wiesel Are an Example that ‘Luck Favors the Prepared Mind’

“Dr. David Hubel, right, celebrating with his longtime collaborator, Dr. Torsten Wiesel, after they won the Nobel Prize in 1981.” Source of caption and photo: online version of the NYT obituary quoted and cited below.

(p. A25) Dr. Hubel and Dr. Wiesel liked to recall that their initial discovery about how vision works resulted from luck. Working in a tiny basement laboratory at Johns Hopkins, the pair struggled for days to coax brain cells in cats to respond to images of dark and light spots. Becoming increasingly frustrated, they waved their arms, jumped around, and, in a moment of levity, displayed images of glamorous women from magazines.

Then, as they shifted a slide in the opthalmoscope, a cell in the cat’s visual cortex suddenly started to fire. The edge of the slide had cast a straight, dark line on the animal’s retina. “It was what the cell wanted, and it wanted it, moreover, in just one narrow range of orientations,” Dr. Hubel said in his Nobel lecture.
They studied the cell for nine hours, and then, Dr. Wiesel recalled, ran down the hall screaming with joy.

Gene-Altered Mice Live 20% Longer

MouseGeneAltertedLivesLonger2013-09-27.jpg “NIH researchers found that lowering the expression of a single gene helped extend the life of mice by about 20%. A mouse with a manipulated gene on the right and an unchanged mouse on the left.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. A3) By reducing the activity of one type of gene, scientists said they increased the average life span of mice by about 20%, a feat that in human terms is akin to extending life by about 15 years.

Moreover, the researchers at the National Institutes of Health found that memory, cognition and some other important traits were better preserved in the mice as they aged, compared with a control group of mice that had normal levels of a protein put out by the gene.
The findings, published Thursday [August 29, 2013] in the journal Cell Reports, strengthen the case that the gene, called mTOR, is a major regulator of the aging process.
. . .
The results . . . build on a growing body of research challenging the belief that aging is an intractable biological process, prompting scientists to think of slowing aging as a possible way to prevent disease.
“What we need right now is for scientists and the public to wake up to the concept that you can slow aging,” said Brian Kennedy, president of the Buck Institute for Aging Research in Novato, Calif., who wasn’t involved in the new study. “If you do, you prevent many of the diseases that we’re so scared of and that are associated with aging.” They include cardiovascular disease, cancer and Alzheimer’s disease.

How to Win the Nobel Prize with Dyslexia

GreiderCarolDyslexicNobelPrizeWinner2013-08-10.jpg “HER TURN; Dr. Carol W. Greider is a researcher at Johns Hopkins.” Source of caption and photo: online version of the NYT interview quoted and cited below.

(p. D1) Q. Did you always want to be a biologist?

A. My parents were scientists. But I wasn’t the sort of child who did science fairs. One of the things I was thinking about today is that as a kid I had dyslexia. I had a lot of trouble in school and was put into remedial classes. I thought that I was stupid.
Q. That must have hurt.
A. Sure. Yes. It was hard to overcome (p. D3) that. I kept thinking of ways to compensate. I learned to memorize things very well because I just couldn’t spell words. So later when I got to take classes like chemistry and anatomy where I had to memorize things, it turned out I was very good at that.
I never planned a career. I had these blinders on that got me through a lot of things that might have been obstacles. I just went forward. It’s a skill that I had early on that must have been adaptive. I enjoyed biology in high school and that brought me to a research lab at U.C. Santa Barbara. I loved doing experiments and I had fun with them. I realized this kind of problem-solving fit my intellectual style. So in order to continue having fun, I decided to go to graduate school at Berkeley. It was there that I went to Liz Blackburn’s lab, where telomeres were being studied.

(p. D3) The number of lizard species in the world — by most counts, around 4,000 — has just increased by one, with the announcement of a new species found on Luzon island in the Philippines.

But this is not a reptile you’d want in a home terrarium. It’s a 6-foot monitor lizard, gray with a spectacular pattern of colorful dots and other markings on its scales.
How did a species of lizard the size of a human remain undetected all these centuries? The answer is it didn’t. “It’s only new to science,” said Rafe M. Brown, an assistant professor at the University of Kansas and senior author of a paper describing the new species, Varanus bitatawa, in Biology Letters.
