Spinning Silk From Whey

Here’s an interesting article. German and Swedish scientists have found a way to make artificial silk from whey protein. From Medical Design Technology:

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY’s research light source PETRA III, the scientists could watch just how small protein pieces, called nanofibrils, lock together to form a fibre. Surprisingly, the best fibres are not formed by the longest protein pieces. Instead, the strongest “silk” is won from protein nanofibrils with seemingly less quality, as the team around Dr. Christofer Lendel and Dr. Fredrik Lundell from the Royal Institute of Technology (KTH) in Stockholm reports in the Proceedings of the U.S. National Academy of Sciences.

Due to its many remarkable characteristics, silk is a material high in demand in many areas. It is lightweight, yet stronger than some metals, and can be extremely elastic. Currently, silk is harvested from farmed silkworms, which is quite costly. “Across the globe, many research teams are working on methods to artificially produce silk,” says co-author Prof. Stephan Roth from DESY who is an adjunct professor at KTH Stockholm. “Such artificial materials can also be modified to have new, tailor-made characteristics and can serve for applications like novel biosensors or self-dissolving wound dressings, for example.”

[…]

In the new study, the nanofibrils were formed by a protein from cow’s whey under the influence of heat and acid. The fibrils shape and characteristics strongly depend on the protein concentration in the solution. At less than four per cent, long, straight and thick fibrils form. They can be up to 2000 nanometres long and four to seven nanometres thick. But at an only slightly higher protein concentration of six per cent or more in the initial solution, the fibrils remain much shorter and thinner with an average length of just 40 nanometres and a thickness of two to three nanometres. Also, they are curved looking like tiny worms and 15 to 25 times softer than the long, straight fibrils.

It’s a lot cheaper to produce artificial silk from whey protein than by farming silk worms. Present strategies for making artificial silk typically start from oil which is, presumably, not a renewable resource. I don’t know what the relative costs are. Those will influence the feasibility of the approach.

It seems to me this sort of technology will be particularly interesting to countries that have substantial dairy surpluses. Like the United States, for example.

I’m in the News

Or, more precisely, my neighborhood is. From ABC 7 Chicago:

A water main break on flooded at least three blocks in Chicago’s Sauganash neighborhood Wednesday morning. A portion of North Kilpatrick Avenue is under at least a foot of water.

The Department of Water Management was notified of the break in the 5900-block of North Kilpatrick Avenue around 3 a.m. An official said a valve failed and crews are having a hard time shutting it off. The water was still gushing out as of 6:50 a.m. They opened up man holes and trying to unclog sewers to ease the pressure.

Kilpatrick is closed between North Caldwell and West Peterson avenues. Caldwell and North Knox Avenue east of Peterson are also closed.

No water in my basement, thank goodness, but our cars are flooded and all of the streets around us are closed. No idea how much damage the cars incurred. It’s possible they’re totaled.

I didn’t notice anything until I stepped out the door to walk the dogs. I guess this explains why I woke at 4:00am.

It’s a bit cold for treading water.

Update

The city just managed to turn off the water. The good news is that the water is starting to recede; the bad news is that we have no water.

They opened the sewers several hours ago to allow the water to drain more easily which it couldn’t do until they managed to turn off the water. That means that all of that water out there has mixed with sewer water which in turn means that I can’t even walk to the corner without wading through two feet of sewage for 150 yards.

To add to the humor of the situation today was trash pickup day which means there are bags of trash floating all over the neighborhood. Who knows where they’ll end up?

Update 2

We’ve already got people going up and down the street selling flood repair services. Fortunately for us, it’s not something we need. Some of our neighbors are not as fortunate.

Update 3

We’ve already called our insurance company; our cars are covered. After they reopen our street the next step will be having the cars towed to the dealership for checkout and possible repair.

Update 4

There’s water inside the cars. In all likelihood both are totaled.

Update 5

The street has been reopened. We’re just waiting for tow trucks now. Fortunately, we have AAA.

Populist Economics

You might want to read the piece at Project Syndicate by Nobel memorial award-winning economist Michael Spence. Here’s his conclusion:

In the next few months, we will learn more about whether the recent uptick in economic optimism is robust; whether Trump’s efforts to fight offshoring and boost growth and employment have a long-term impact; and whether protectionism prevails. Only then can we determine whether Trump really was the right economic choice for America’s disaffected workers.

The “certainties” he notes are:

  • Expectations matter
  • Nominal growth in the U. S. will rise
  • Pressure on U. S. companies to maintain their reputations
  • Continued development in digital technology

Beyond there lie dragons.

El-Erian’s Detective Work

At Bloomberg View Mohammed El-Erian sees a pattern emerging in Donald Trump’s approach to the economy. The features he identifies are:

  • t is targeting higher growth and greater job creation using what can be called an “import- substitution-plus” approach to policy making, together with elements of an industrial policy
  • It operates both at the micro and macro levels
  • It actively uses signals and narratives as economic policy tools
  • It is underpinned by a carrot and stick philosophy
  • When it comes to cross-border relationships, the administration isn’t shy about upending multidecade constants in U.S. economic policy making

He concludes:

If sustained, the impact of Trump’s approach would extend well beyond changes to the internal workings and orientations of the U.S. economy, including how it picks and chooses the way it interacts with the global economy. Given that the U.S. is at the core of the international monetary system, what happens here would not stay here. It would most likely trigger reactions from other countries while potentially also shaking the conventional functioning of a rule-based global system.

We’ll see. I’d bet that it will be a lot more transactional than that.

Ah, well. It’s the nature of human beings to attempt identify patterns even where none exist. Maybe there will actually be a pattern, maybe there won’t.

Not So Silent

The most famous statement of Calvin Coolidge, president of the United States from 1923 to 1929, is usually misquoted as “the business of America is business”. The original version of that was from President Coolidge’s address to the American Society of Newspaper Editors, quoted here in full, given almost a century ago on January 17, 1925:

The relationship between governments and the press has always been recognized as a matter of large importance. Wherever despotism abounds, the sources of public information are the first to be brought under its control. Where ever the cause of liberty is making its way, one of its highest accomplishments is the guarantee of the freedom of the press. It has always been realized, sometimes instinctively, oftentimes expressly, that truth and freedom are inseparable. An absolutism could never rest upon any thing save a perverted and distorted view of human relationships and upon false standards set up and maintained by force. It has always found it necessary to attempt to dominate the entire field of education and instruction. It has thrived on ignorance. While it has sought to train the minds of a few, it has been largely with the purpose of attempting to give them a superior facility for misleading the many. Men have been educated under absolutism, not that they might bear witness to the truth, but that they might be the more ingenious advocates and defenders of false standards and hollow pretenses. This has always been the method of privilege, the method of class and caste, the method of master and slave.

When a community has sufficiently advanced so that its government begins to take on that of the nature of a republic, the processes of education become even more important, but the method is necessarily reversed. It is all the more necessary under a system of free government that the people should be enlightened, that they should be correctly informed, than it is under an absolute government that they should be ignorant. Under a republic the institutions of learning, while bound by the constitution and laws, are in no way subservient to the government. The principles which they enunciate do not depend for their authority upon whether they square with the wish of the ruling dynasty, but whether they square with the everlasting truth. Under these conditions the press, which had before been made an instrument for concealing or perverting the facts, must be made an instrument for their true representation and their sound and logical interpretation. From the position of a mere organ, constantly bound to servitude, public prints rise to a dignity, not only of independence, but of a great educational and enlightening factor. They attain new powers, which it is almost impossible to measure, and become charged with commensurate responsibilities.

The public press under an autocracy is necessarily a true agency of propaganda. Under a free government it must be the very reverse. Propaganda seeks to present a part of the facts, to distort their relations, and to force conclusions which could not be drawn from a complete and candid survey of all the facts. It has been observed that propaganda seeks to close the mind, while education seeks to open it. This has become one of the dangers of the present day.

The great difficulty in combating unfair propaganda, or even in recognizing it, arises from the fact that at the present time we confront so many new and technical problems that it is an enormous task to keep ourselves accurately informed concerning them. In this respect, you gentlemen of the press face the same perplexities that are encountered by legislators and government administrators. Whoever deals with current public questions is compelled to rely greatly upon the information and judgments of experts and specialists. Unfortunately, not all experts are to be trusted as entirely disinterested. Not all specialists are completely without guile. In our increasing dependence on specialized authority, we tend to become easier victims for the propagandists, and need to cultivate sedulously the habit of the open mind. No doubt every generation feels that its problems are the most intricate and baffling that have ever been presented for solution. But with all recognition of the disposition to exaggerate in this respect, I think we can fairly say that our times in all their social and economic aspects are more complex than any past period. We need to keep our minds free from prejudice and bias. Of education, and of real information we cannot get too much. But of propaganda, which is tainted or perverted information, we cannot have too little.

Newspaper men, therefore, endlessly discuss the question of what is news. I judge that they will go on discussing it as long as there are newspapers. It has seemed to me that quite obviously the news giving function of a newspaper cannot possibly require that it give a photographic presentation of everything that happens in the community. That is an obvious impossibility. It seems fair to say that the proper presentation of the news bears about the same relation to the whole field of happenings that a painting does to a photograph. The photograph might give the more accurate presentation of details, but in doing so it might sacrifice the opportunity the more clearly to delineate character. My college professor was wont to tell us a good many years ago that if a painting of a tree was only the exact representation of the original, so that it looked just like the tree, there would be no reason for making it; we might as well look at the tree itself. But the painting, if it is of the right sort, gives something that neither a photograph nor a view of the tree conveys. It emphasizes something of character, quality, individuality. We are not lost in looking at thorns and defects; we catch a vision of the grandeur and beauty of a king of the forest.

And so I have conceived that the news, properly presented, should be a sort of cross section of the character of current human experience. It should delineate character, quality, tendencies and implications. In this way the reporter exercises his genius. Out of the current events he does not make a drab and sordid story, but rather an in forming and enlightened epic. His work becomes no longer imitative, but rises to an original art.

Our American newspapers serve a double purpose. They bring knowledge and information to their readers, and at the same time they play a most important part in connection with the business interests of the community, both through their news and advertising departments. Probably there is no rule of your profession to which you gentlemen are more devoted than that which prescribes that the editorial and the business policies of the paper are to be conducted by strictly separate departments. Editorial policy and news policy must not be influenced by business consideration; business policies must not be affected by editorial programs. Such a dictum strikes the outsider as involving a good deal of difficulty in the practical adjustments of every day management. Yet, in fact, I doubt if those adjustments are any more difficult than have to be made in every other department of human effort. Life is a long succession of compromises and adjustments, and it may be doubted whether the press is compelled to make them more frequently than others do.

When I have contemplated these adjustments of business and editorial policy, it has always seemed to me that American newspapers are peculiarly representative of the practical idealism of our country. Quite recently the construction of a revenue statute resulted in giving publicity to some highly interesting facts about incomes. It must have been observed that nearly all the newspapers published these interesting facts in their news columns, while very many of them protested in their editorial columns that such publicity was a bad policy. Yet this was not inconsistent. I am referring to the incident by way of illustrating what I just said about the newspapers representing the practical idealism of America. As practical newsmen they printed the facts. As editorial idealists they protested that there ought to be no such facts available.

Some people feel concerned about the commercialism of the press. They note that great newspapers are great business enterprises earning large profits and controlled by men of wealth. So they fear that in such control the press may tend to support the private interests of those who own the papers, rather than the general interest of the whole people. It seems to me, however, that the real test is not whether the newspapers are controlled by men of wealth, but whether they are sincerely trying to serve the public interests. There will be little occasion for worry about who owns a newspaper, so long as its attitudes on public questions are such as to promote the general welfare. A press which is actuated by the purpose of genuine usefulness to the public interest can never be too strong financially, so long as its strength is used for the support of popular government.

There does not seem to be cause for alarm in the dual relationship of the press to the public, whereby it is on one side a purveyor of information and opinion and on the other side a purely business enterprise. Rather, it is probable that a press which maintains an intimate touch with the business currents of the nation, is likely to be more reliable than it would be if it were a stranger to these influences. After all, the chief business of the American people is business. They are profoundly concerned with producing, buying, selling, investing and prospering in the world. I am strongly of opinion that the great majority of people will always find these are moving impulses of our life. The opposite view was oracularly and poetically set forth in those lines of Goldsmith which everybody repeats, but few really believe:

Ill fares the land, to hastening ills a prey,
Where wealth accumulates, and men decay.

Excellent poetry, but not a good working philosophy. Goldsmith would have been right, if, in fact, the accumulation of wealth meant the decay of men. It is rare indeed that the men who are accumulating wealth decay. It is only when they cease production, when accumulation stops, that an irreparable decay begins. Wealth is the product of industry, ambition, character and untiring effort. In all experience, the accumulation of wealth means the multiplication of schools, the increase of knowledge, the dissemination of intelligence, the encouragement of science, the broadening of outlook, the expansion of liberties, the widening of culture. Of course, the accumulation of wealth can not be justified as the chief end of existence. But we are compelled to recognize it as a means to well nigh every desirable achievement. So long as wealth is made the means and not the end, we need not greatly fear it. And there never was a time when wealth was so generally regarded as a means, or so little regarded as an end, as today. Just a little time ago we read in your newspapers that two leaders of American business, whose efforts at accumulation had been most astonishingly successful, had given fifty or sixty million dollars as endowments to educational works. That was real news. It was characteristic of our American experience with men of large resources. They use their power to serve, not themselves and their own families, but the public. I feel sure that the coming generations, which will benefit by those endowments, will not be easily convinced that they have suffered greatly because of these particular accumulations of wealth.

So there is little cause for the fear that our journalism, merely because it is prosperous, is likely to betray us. But it calls for additional effort to avoid even the appearance of the evil of selfishness. In every worthy profession, of course, there will always be a minority who will appeal to the baser instinct. There always have been, and probably always will be some who will feel that their own temporary interest may be furthered by betraying the interest of others. But these are becoming constantly a less numerous and less potential element in the community. Their influence, whatever it may seem at a particular moment, is always ephemeral. They will not long interfere with the progress of the race which is determined to go its own for ward and upward way. They may at times somewhat retard and delay its progress, but in the end their opposition will be overcome. They have no permanent effect. They accomplish no permanent result. The race is not traveling in that direction. The power of the spirit always prevails over the power of the flesh. These furnish us no justification for interfering with the freedom of the press, because all freedom, though it may sometime tend toward excesses, bears within it those remedies which will finally effect a cure for its own disorders.

American newspapers have seemed to me to be particularly representative of this practical idealism of our people. Therefore, I feel secure in saying that they are the best newspapers in the world. I believe that they print more real news and more reliable and characteristic news than any other newspaper. I believe their editorial opinions are less colored in influence by mere partisanship or selfish interest, than are those of any other country. Moreover, I believe that our American press is more independent, more reliable and less partisan today than at any other time in its history. I believe this of our press, precisely as I believe it of those who manage our public affairs. Both are cleaner, finer, less influenced by improper considerations, than ever before. Whoever disagrees with this judgment must take the chance of marking himself as ignorant of conditions which notoriously affected our public life, thoughts and methods, even within the memory of many men who are still among us.

It can safely be assumed that self interest will always place sufficient emphasis on the business side of newspapers, so that they do not need any outside encouragement for that part of their activities. Important, however, as this factor is, it is not the main element which appeals to the American people. It is only those who do not understand our people, who believe that our national life is entirely absorbed by material motives. We make no concealment of the fact that we want wealth, but there are many other things that we want very much more. We want peace and honor, and that charity which is so strong an element of all civilization. The chief ideal of the American people is idealism. I cannot repeat too often that America is a nation of idealists. That is the only motive to which they ever give any strong and lasting reaction. No newspaper can be a success which fails to appeal to that element of our national life. It is in this direction that the public press can lend its strongest support to our Government. I could not truly criticize the vast importance of the counting room, but my ultimate faith I would place in the high idealism of the editorial room of the American newspaper.

I think there’s a lot to like in that speech. It was a different day, of course. Nowadays the path to wealth lies through rent-seeking. And President Coolidge’s depiction of newspaper editors is barely recognizeable today.

The Greatest Female Television Star

Among the accolades being heaped on Mary Tyler Moore following her death, she is being called the “greatest female television star ever”. That is untrue, illustrating only how ignorant of history Americans are.

In three consecutive decades, in 1951 through 1956, 1962 through 1969, and 1970 through 1972, among the top 10 television programs there was always one starring Lucille Ball: I Love Lucy, Here’s Lucy, or The Lucy Show. In many of those years her show was the top-rated show. No other television performer, male or female, has accomplished anything to equal that.

Additionally, the production company that she co-founded, Desilu, produced dozens of the most highly rated and significant programs in television history including, in addition to her own programs, The Jack Benny Program, The Danny Thomas Show, The Andy Griffith Show, The Dick Van Dyke Show, I Spy, and Mission: Impossible, just to name a few. As the creative force behind Desilu Lucy was directly responsible for That Girl, the immediate antecedent of The Mary Tyler Moore Show in depicting a single woman trying to “make it on her own”, and Star Trek, cultivating them and promoting them. Practically every program featuring a single, independent woman with a career prior to The Mary Tyler Moore Show was produced by Desilu.

Desilu was the first production company to use film (rather than live production), the first to use a multi-camera setup, and the first production company to cast a black man as the star of a major television program. In a very real sense Desilu created modern television.

To say that Ms. Moore followed in Lucille Ball’s footsteps is no exaggeration. It is directly and specifically the truth.

So, hat’s off to Lucy. Personally, I never cared much for any of the incarnations of her own program (I loved her in the movies) but there’s no doubt in my mind that she was the greatest, the champ.

Mary Tyler Moore, 1936-2017

I first became aware of Mary Tyler Moore nearly 60 years ago. More precisely, I became aware of her legs, occasionally her lips, and her low, sultry voice when she portrayed Richard Diamond’s telephone answering service on the TV program Richard Diamond, Private Investigator, known only as “Legs”. What can I say? It was the 1950s, a different world.

Then she was Laura Petrie, formerly a talented dancer and then the long-suffering wife of comedy writer Rob Petrie on The Dick Van Dyke Show. A wife and mother. And then she was Mary Richards, a young woman struggling to “make it after all” with a career in television news production. There’s a statue of Mary Richards in downtown Minneapolis.

For twenty years her personae documented the changes in American society from the 1950s to the 1970s, each of the roles iconic. Now Mary Tyler Moore has died. From her obituary in the New York Times:

Mary Tyler Moore, whose witty and graceful performances on two top-rated television shows in the 1960s and ’70s helped define a new vision of American womanhood, died on Wednesday in Greenwich, Conn. She was 80.

Her family said her death, at Greenwich Hospital, was caused by cardiopulmonary arrest after she had contracted pneumonia.

Ms. Moore faced more than her share of private sorrow, and she went on to more serious fare, including an Oscar-nominated role in the 1980 film “Ordinary People” as a frosty, resentful mother whose son has died. But she was most indelibly known as the incomparably spunky Mary Richards on the CBS hit sitcom “The Mary Tyler Moore Show.” Broadcast from 1970 to 1977, it was produced by both Ms. Moore and her second husband, the CBS executive Grant Tinker, who died on Nov. 28.

She had a few prominent movie roles and her own television production company but she will be remembered for her television stardom and the always-endearing characters she played there.

Second Sourcing the iPhone

I’ve been waiting for this. CNN reports that Apple is considering beginning to manufacture the iPhone in India:

Apple executives met with Indian government officials on Wednesday to discuss a plan to make iPhones in the southern city of Bangalore, a person familiar with the talks told CNNMoney.

India’s commerce ministry confirmed that the meeting took place but declined to comment on what was discussed. In a statement, Apple (AAPL, Tech30) said it appreciated the “constructive and open dialogue we’ve had with government about further expanding our local operations.” But it would not go into detail.

Apple’s plans to set up an iPhone production plant in India’s main tech hub were first reported by the Times of India. The factory would be built in partnership with Taiwan-based manufacturer Wistron, the newspaper reported.

I think there are multiple reasons for Apple to want to do this. For one thing it should give them greater access to the Indian market.

But, importantly, it would give them a second source for iPhones if China becomes difficult or too expensive. It’s just prudent management.

If this actually comes to pass I don’t believe it means the company will cease production in China or that it will abandon the announced plan to start manufacturing iPhones in the United States. I also wouldn’t be surprised if the locations build different models.

Who Do You Trust?

This might be an interesting story to follow. CNNMoney remarks on President Trump’s distrust of the Bureau of Labor Statistics’s unemployment figures:

White House press secretary Sean Spicer sidestepped a simple question about the national unemployment rate. Trump’s nominee to run the Labor Department has written that the government should ditch the figure because it’s “misleading.”

And Trump himself has said the unemployment rate is a hoax, even claiming once that he had “heard” it could be as high as 42%. It was a hair over 5% at the time.

Economists find this pattern concerning. For decades, the unemployment rate has been one of the basic barometers by which America’s economy is judged. While no single metric is infallible, economists say, the unemployment rate does a pretty good job.

And they say trying to delegitimize it would be bad news.

“I think it’s very, very dangerous. The Bureau of Labor Statistics does an excellent job,” said Bill Rodgers, a professor at Rutgers’ Center for Workforce Development and chief economist for the Labor Department from 2000 to 2001.

Bob Murphy, a White House economist under former President Bill Clinton who teaches at Boston College, said the process and statistical analysis that go into producing the unemployment rate are “rock solid.”

It might be good economics or good politics but I’d need to be convinced that it’s good science. The headline unemployment rate number reported by the BLS incorporates a number of adjustments, not the least of which is what’s referred to as the “birth/death adjustment”, a fudge factor that’s applied to the actual number of jobs divined from surveys based on the historical experience with businesses that open or close. It has been known for some time that the model the BLS for that needs recalibrating and they appear to have been doing that over time.

The problem that I see is that the adjustment is just too large. I’m suspicious whenever the fudge factors exceed the size of actual measured changes.

Another problem is that the BLS’s numbers just don’t feel right. Based on the BLS’s unemployment calculations we’re at full employment but it doesn’t feel like we’re at full employment. That’s hard to quantify but it’s real just the same.

And, of course, you need to distinguish between the actual issue and the turf war over the issue.

As I say, it will be interesting to follow this story.

The Political Divide

Some evidence is emerging that the great political divide in the United States isn’t between Donald Trump and the citizenry but between elites and the citizenry. Politico reports that a lot more voters liked Donald Trump’s speech following his inauguration than disliked it:

A new POLITICO/Morning Consult poll shows that the new president’s message is resonating with voters, refuting the idea that Trump bungled his first speech as commander in chief.

Trump got relatively high marks on his Friday address, with 49 percent of those who watched or heard about the speech saying it was excellent or good, and just 39 percent rating it as only fair or poor. Sixty-five percent of those surveyed reacted positively to the “America First” message, the cornerstone of the Trump campaign and governing posture.

Americans are looking for Trump to put his slogan into action: 61 percent said they agreed with Trump’s plan that the federal government should “buy American and hire American.”

“President Trump knows what his voters like to hear, and you see that resonating once again in our latest poll,” said Kyle Dropp, Morning Consult’s chief research officer and co-founder.

There are all sorts of possible explanation for the seeming contradiction between those results and what we’ve been hearing from the media for the last week. It may just be that Americans want to like their presidents.

It could be that pundits see things very differently than most voters. We have a larger percentage of non-citizens in the United States that at any time in living memory and the largest absolute number ever. Limiting the poll to voters would not include those non-citizens. It could be that things look very different in the place where our journalists and pundits live. The poll could be wrong.

It could be that 69% of Americans are deplorable.
