“Hurricane Superstar” Had No Use For Global Warming

(p. 24) William M. Gray, whose pioneering research helped him make hurricane predictions for three decades and allowed the East Coast and the Caribbean to gird for their fury, died on Saturday [April 23, 2016] in Fort Collins, Colo. He was 86.
. . .
Dr. Gray issued his first data-driven seasonal forecast in 1984. He eventually aggregated measures of atmospheric conditions, water current and water temperature to predict the number and intensity of tropical storms, rather than their paths or potential landfalls.
. . .
Dr. Gray was skeptical about the causes of climate change, prompting vitriolic exchanges with other scientists. Judith A. Curry, who was chairwoman of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, accused him of “brain fossilization.”
Dr. Gray was less alarmed than many of his colleagues at the rate of climate change and attributed it to natural causes, like the circulation of heat-bearing ocean currents, rather than to the human-made greenhouse effect of heat-trapping gasses from burning fossil fuels like coal and oil.
“After unveiling the first Atlantic seasonal hurricane forecasting system in 1984, he became a hurricane superstar and darling of the media,” Chris Mooney wrote in 2007 in “Storm World: Hurricanes, Politics, and the Battle Over Global Warming.” “But he had absolutely no use for the notion of global warming, much less the idea that it might seriously affect the storms he’d spent a lifetime studying. And he had no problem saying so — loudly and often.”
In an interview with Westword, a Denver online newsletter, in 2006, Dr. Gray said, “When I am pushing up daisies, I am very sure that we will find that humans have warmed the globe slightly, but that it’s nothing like what they’re saying.”

Churchill’s “Natural Curiosity and General Optimism about Life”

(p. A11) In a newly unearthed essay sent to his publisher on Oct. 16, 1939 — just weeks after Britain entered World War II and Churchill became part of the wartime cabinet — and later revised, he was pondering the likelihood of life on other planets.
. . .
The manuscript was passed on to the National Churchill Museum in Fulton, Mo., the site of famed 1946 Iron Curtain speech, in the 1980s by Wendy Reves, the wife of Churchill’s publisher, Emery Reves. It had been overlooked for years until Timothy Riley, who became the museum’s director last year, stumbled upon it recently. Soon after news of the discovery, two other copies were found in a separate archive in Britain.
. . .
Largely self-educated in the sciences, Churchill had boundless curiosity for practically anything, an attitude he once described as “picking up a few things as I went along.”
. . .
He was the first prime minister to hire a science adviser. Frederick Lindemann, a physicist, became Churchill’s “on tap” expert and once described him as a “scientist who had missed his vocation,” said Andrew Nahum, who organized an exhibition on Churchill and science at the Science Museum in London. He found a separate copy of the essay in the Churchill Archives Center at the University of Cambridge.
. . .
In the interwar period, Churchill wrote numerous scientific articles, including one called “Death Rays” and another titled “Are There Men on the Moon?” In 1924, he published a text asking readers “Shall We All Commit Suicide?” in which he speculated that technological advances could lead to the creation of a small bomb that was powerful enough to destroy an entire town.
Churchill’s recently unearthed article on extraterrestrial life was probably written in the same vein and was probably intended to be published as a popular science piece for a newspaper.
Two other scientific essays — one on cell division in the body and another on evolution — are stored in the museum’s archives in Fulton, Mr. Riley, the museum director, said in an interview.
Churchill had a “natural curiosity and general optimism about life,” Mr. Riley said. He had “a willingness to see technical and scientific advances improve not only his immediate world or his country, but the world.”

“Insects Can Solve Problems, They Can Learn”

(p. D6) Never underestimate the power of the bee brain.
In the latest triumph for one of humanity’s favorite insects, bumblebees learned how to push a ball to the center of a platform for a sugary treat.
That may not make them a threat on the chess board, but soccer or even Skee-Ball might be within their intellectual grasp — if it were scaled down in size, of course.
The new research finding is one more reason that scientists who study insects, of all sorts, would like to point out that just because a brain is small, doesn’t mean it is simple.
Clint Perry, one of the bumblebee trainers at Queen Mary University of London, and a confirmed small brain partisan, said, “I’ve actually been asked if bees have brains.”
In fact, a number of recent experiments have shown that “insects can solve problems, they can learn,” he said. And scientists have yet to define the limits of insects’ mental abilities.
. . .
The task of pushing a little ball to the center of a platform was completely arbitrary. Bees don’t do anything like this in nature, where they seek out flowers for nectar and pollen. So it was a brand new behavior demanding some kind of general ability to learn.
The way the bees learned was important, too. They were pre-trained to expect a treat in the center of a platform. But having to push a ball to the center to get the treat was something they hadn’t seen.
Then the researchers tried several ways of teaching the bees what to do. The bees learned best by watching a fellow bee perform the feat. After that kind of observation, 10 of 10 bees solved the problem on the first try. On later tries, they continued to improve, taking less time.

Amateur Inventors Are Crowdsourced to Solve Scientific Problems

(p. A3) At his laboratory console, Rhiju Das is making a game of a pressing public-health problem. He is recruiting thousands of videogamers to develop a better test for tuberculosis, which infects about one-third of the world’s population.
All they have to do is design a single molecule that can diagnose the disease in a patient’s bloodstream quickly, easily and cheaply–a task that so far has eluded public-health experts. To muster a crowd of amateurs to attempt it, Dr. Das, a biochemist at the Stanford University School of Medicine, and his colleagues this week launched the OpenTB challenge on a Web-based videogame called Eterna.
“The players themselves are going to be the inventors,” said Dr. Das. “Any molecule that a top player can make in the game, we will test it in the laboratory.”
. . .
In a game called Phylo, developed at McGill University, 300,000 players have been cross-indexing disease-related DNA sequences from dozens of species. And in Quantum Moves, conceived at Aarhus University in Denmark, 10,000 players are applying the bizarre laws of quantum mechanics to improve computer design.
“The number of projects has exploded,” said McGill computer scientist Jerome Waldispuhl, who co-founded the Phylo project.
Despite initial misgivings about the accuracy of crowdsourced research, players have produced reliable results and a dozen or so peer-reviewed research papers.
Typically, the players drawn to the science games have no special scientific expertise. They usually are intrigued by the chance to make a useful contribution to research in their spare time.
. . .
By harnessing human intuition and visual perception, these crowdsourcing games highlight differences between human and machine intelligence, several game designers said. “All of these citizen-science projects are like a snapshot of what is uniquely human at the moment,” said physicist Jacob Sherson at Aarhus University who helped to design Quantum Moves.

Best Sleep When Temperature Is 64-68 Degrees Fahrenheit

(p. 2) A poor night’s sleep is an all too common problem when you’re staying at a hotel, says Alistair Hughes, the managing director of Savoir Beds, a London-based company that sells beds and handmade mattresses to more than 50 hotels globally.
. . .
A quiet, dark, cool room is the ideal environment for sleeping well, Mr. Hughes said. Create this ambience by having ear plugs to block noise, using the blackout blinds your room likely has and setting the temperature to between 64 and 66 degrees Fahrenheit.

“Many of Our Worst Behaviors Are in Retreat”

(p. A19) Mr. Sapolsky is one of those very few eminent scientists who are also eminent–or even coherent–when writing for the general public.
. . .
The author’s comprehensive approach integrates controlled laboratory investigation with naturalistic observations and study. To his immense credit, he doesn’t omit cultural norms, social learning, the role of peer pressure or historical tradition. He also has a delightfully self-deprecating sense of humor. Introducing a chapter titled “War and Peace,” he summarizes the chapter’s goals as: (a) to demonstrate that “many of our worst behaviors are in retreat, our best ones ascendant”; (b) to examine “ways to improve this further”; (c) to derive “emotional support for this venture” (d) and, “finally, to see if I can actually get away with calling this chapter ‘War and Peace.’ ” Earlier, after an especially abstruse sentence, he adds a footnote: “I have no idea what it is that I just wrote.”
. . .
It’s no exaggeration to say that “Behave” is one of the best nonfiction books I’ve ever read. .

Gene Editing of Embryos Promises to Cure Inherited Diseases

(p. A13) For the first time in the United States, scientists have edited the genes of human embryos, a controversial step toward someday helping babies avoid inherited diseases.
. . .
The Oregon scientists reportedly used a technique called CRISPR, which allows specific sections of DNA to be altered or replaced. It’s like using a molecular scissors to cut and paste DNA, and is much more precise than some types of gene therapy that cannot ensure that desired changes will take place exactly where and as intended. With gene editing, these so-called “germline” changes are permanent and would be passed down to any offspring.
The approach holds great potential to avoid many genetic diseases, . . .
. . .
One prominent genetics expert, Dr. Eric Topol, director of the Scripps Translational Science Institute in La Jolla, California, said gene editing of embryos is “an unstoppable, inevitable science, and this is more proof it can be done.”
Experiments are in the works now in the U.S. using gene-edited cells to try to treat people with various diseases, but “in order to really have a cure, you want to get this at the embryo stage,” he said.

Equal Opportunity Gene Innovation

(p. R4) Kian Sadeghi has postponed homework assignments, sports practice and all the other demands of being a 17-year-old high-school junior for today. On a Saturday afternoon, he is in a lab learning how to use Crispr-Cas9, a gene-editing technique that has electrified scientists around the world–. . .
. . .
Crispr-Cas9 is easier, faster and cheaper than previous gene-editing techniques.
. . .
A do-it-yourself Crispr kit with enough material to perform five experiments gene-editing the bacteria included in the package is available online for $150. Genspace, the Brooklyn, N.Y., community lab where Mr. Sadeghi is learning how to use Crispr to edit a gene in brewer’s yeast, charges $400 for four intensive sessions. More than 80 people have taken the classes since the lab started offering them last year.
. . .
In the workshop, if the participants correctly edit the gene in brewer’s yeast, the cells will turn red. In between the prep work, the classmates swap stories on why they are there. Many have personal Crispr projects in mind and want to learn the technique.
Kevin Wallenstein, a chemical engineer, takes a two-hour train ride to the lab from his home in Princeton, N.J. Crispr is a hobby for him, he says. He wants to eventually use it to edit a gene in an edible fruit that he prefers not to name, to restore it to its historical color. “I always wondered what it would look like,” he says.
At the workshop, Mr. Wallenstein shares his Crispr goal with Will Shindel, Genspace’s lab director. Mr. Shindel is enthusiastic; he has started his own Crispr project, a longtime dream to make a spicy tomato. Both men say they aren’t looking to commercialize their ideas–but they would like to eat what they create someday, if they get permission from the lab. “I’m doing it for fun,” Mr. Shindel says.
When Mr. Sadeghi first wanted to try Crispr, the teenager emailed 20 scientists asking if they would be willing to let him learn Crispr in their labs. Most didn’t respond; those that did turned him down. So he did a Google search and stumbled upon Genspace. When he shared the lead with his science teacher at the Berkeley Carroll School in Brooklyn, Essy Levy Sefchovich, she agreed to take the course with him.
When Mr. Shindel describes the steps of the experiment, Ms. Sefchovich takes notes. She is hoping to create a modified version of the yeast experiment so all her students can try Crispr in class.
Later, Mr. Sadeghi recounts that the hardest part of the day was handling the micropipette, the lab tool he used to mix small amounts of liquid. He says he still feels clumsy. Ms. Sefchovich reassures him he’ll get the hang of it; he just needs to practice.
“It’s like driving,” she tells him. “You learn the right feel.” Mr. Sadeghi doesn’t have his driver’s license yet. He figures he’ll do Crispr first.

“Unfettered Science, If We Have the Courage to Let It Unfold”

(p. 26) “How to Tame a Fox” sets out to answer a simple-seeming question: What makes a dog a dog? Put another way, how did an animal that started out as a bloodthirsty predator become one that now wants nothing more than a nice belly rub and the chance to gaze adoringly at a member of another species? In the late 1950s, a Russian scientist named Dmitri Belyaev decided to address this puzzle by taking the unheard-of tack of replicating the domestication process in real time. He and his colleagues took silver foxes, widely bred in vast Siberian farms for their luxurious pelts, and made them into friendly house pets. It was a deceptively simple process: Take the puppies from only the friendliest foxes, breed them and repeat. Lyudmila Trut, the current lead researcher of the silver fox experiment, who began work as Belyaev’s intern, along with Lee Alan Dugatkin, an American scientist and writer at the University of Louisville, documents their monumental effort in this sparkling new book.
Belyaev died in 1985, but the experiment is still ongoing, with 56 generations of foxes bred to date — a far cry from the snarling creatures that used to snap at the hands of their caretakers when the research began. The new foxes run toward people, jump on the bed and nuzzle one another as well as their human caretakers. Such a behavioral transformation was to some degree expected, since they were bred from the tamest members of their groups. Perhaps more intriguing, they also look more doglike, with floppy ears, wagging tails and piebald fur.
. . .
The book, . . . , is not only about dogs, or foxes, or even science under siege from political interests. . . . It may serve — particularly now — as a parable of the lessons that can emerge from unfettered science, if we have the courage to let it unfold.

“The Data Run Counter to Your Anecdotes”

(p. A13) “Shattered,” by campaign reporters Jonathan Allen and Amie Parnes, narrates the petty bickering, foolish reasoning and sheer arrogance of a campaign that was never the sure thing that its leader and top staffers assumed. The authors, in a mostly successful attempt to get their sources to talk candidly, promised them that they wouldn’t be identified.
. . .
The juicy quotes would mean more if they were on the record, but mostly it works: You can’t pinpoint the identity of any one “top aide” or “close Hillary ally,” but the authors’ language leads you to believe they include the most senior Clinton advisers–Mr. Podesta, longtime Clinton confidante Huma Abedin, campaign manager Robby Mook, speechwriter Dan Schwerin, policy adviser Jake Sullivan –and probably the candidate herself.
. . .
Successful politicians must have a tacit sense of what voters want to hear and how they might be persuaded. Mrs. Clinton–in stark contrast to her husband–was never interested in that component of campaigning. You got the feeling she didn’t like people all that much.
Mr. Mook’s scientific “model” of how the campaign should run emphasized demographics, constituents’ voting histories, regional electoral patterns, and so on. When staffers objected to his directives, the authors record, the response was always the same: “The data,” as Mr. Mook at one point put it to former President Bill Clinton, “run counter to your anecdotes.”

Since 1880 North America Is Warmer by One and a Half Degrees Fahrenheit

(p. A23) Anyone who has read the 2014 report of the Intergovernmental Panel on Climate Change knows that, while the modest (0.85 degrees Celsius, or about 1.5 degrees Fahrenheit) warming of the earth since 1880 is indisputable, as is the human influence on that warming, much else that passes as accepted fact is really a matter of probabilities. That’s especially true of the sophisticated but fallible models and simulations by which scientists attempt to peer into the climate future. To say this isn’t to deny science. It’s to acknowledge it honestly.
