The Earth's atmosphere is protected by a magnetosphere, but Mars lacks this protective shield and lost its atmosphere to space long ago through interactions with the solar wind. In a new paper, scientists report that they have directly observed this process of "atmospheric sputtering," watching how incoming ions from the solar wind directly cause neutral atmospheric particles to escape. They found the process is stronger than anticipated, especially in solar storms.
The Sun's surface has unveiled a new secret: ultra fine magnetic "curtains" that create striking patterns of bright and dark stripes across the solar photosphere. Thanks to groundbreaking observations from the NSF Daniel K. Inouye Solar Telescope in Hawaii, scientists have captured the sharpest ever images of these previously unseen structures, revealing magnetic field variations at scales as small as 20 kilometres.
Well, you might disagree with the quote, taken from the video below, but you have to admit that this bird is something speciesl. It’s the tropical royal flycatcher (Onychorhynchus coronatus) that I’ve never seen in my perambulations in the tropical forests of Guatemala, Costa Rica, Peru or Ecuador, though it lives there and, according to Wikipedia, lives “in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay” Here’s its range map from eBird. where you can also hear its squeaky call:
The taxonomy is confusing, with some bird systematists recognizing five subspecies. However, what you want to look at is this amazing crest, which is normally hidden. Again from Wikipedia:
The tropical royal flycatcher is approximately 12.5 to 18 cm (4.9 to 7.1 in) long and weighs 9.7 to 21 g (0.34 to 0.74 oz). It has an erectile fan-shaped crest. In the nominate subspecies O. c. coronatus it is red with blue tips in the male and yellow or orange in the female. The sexes’ plumages are otherwise alike.
The male takes up the first minute of this video; the rest of the video, well worth watching, shows other amazing birds. I have seen the potoo, but it had to be pointed out to me because it looks exactly like a tree branch. (We’ll have a “readers’ wildlife post on the potoo soon.)
Imagine being the first explorer to come across one of these birds!
It's quite the journey from "RCT or STFU" to "we will always have a place for controlled clinical studies."
The post Dr. Vinay Prasad is Repeatedly Undermining RCTs. Why? first appeared on Science-Based Medicine.As I’ve mentioned, one could describe the situation in Los Angeles a “shitshow” or a “dumpster fire”. My take about what happened is that ICE (or other law enforcement officials) went to arrest undocumented immigrants in L.A., but were blocked or impeded by huge protests by American civilians. Both protestors and law enforcement officials were masked: the former, along with the vandalism and violence, shows that the protestors were not committing classical civil disobedience, but didn’t want to be identified; the latter seems unconscionable because law enforcement should not be masked, and should be identifiable. Yes, many demonstrators remained peaceful, but there’s no doubt that there was violence along with attempts to kill or injure law enforcement.
The violence involved protestors setting cars on fire, looting, and worse, firing serious fireworks (Roman candles and M80s) at law enforcement. I don’t think law enforcement provoked these protests, but they did respond with tear gas and flashbangs. At this point, despite the objections of California governor Gavin Newsom, Trump deputized the California National Guard to intervene and protect law enforcement. 4,000 National Guard people were involved, though it’s not clear what, exactly they did. Nevertheless, Newsom has filed a lawsuit against Trump for calling in the Guard.
Then, apparently on Trump’s orders, 700 U.S. Marines were also sent to L.A. to further control the situation. Newsom has also threatened to sue for this as well.
The use of both National Guard and Marines has been widely condemned by the media, especially the progressive or left-wing media. For example, the NYT’s Michelle Goldberg has an op-ed today, “This is what autocracy looks like.” A few quotes:
Since Donald Trump was elected again, I’ve feared one scenario above all others: that he’d call out the military against people protesting his mass deportations, putting America on the road to martial law. Even in my more outlandish imaginings, however, I thought that he’d need more of a pretext to put troops on the streets of an American city — against the wishes of its mayor and governor — than the relatively small protests that broke out in Los Angeles last week.
In a post-reality environment, it turns out, the president didn’t need to wait for a crisis to launch an authoritarian crackdown. Instead, he can simply invent one.
It’s true that some of those protesting Immigration and Customs Enforcement raids in Los Angeles have been violent; on Sunday one man was arrested for allegedly tossing a Molotov cocktail at a police officer, and another was accused of driving a motorcycle into a line of cops. Such violence should be condemned both because it’s immoral and because it’s wildly counterproductive; each burning Waymo or smashed storefront is an in-kind gift to the administration.
But the idea that Trump needed to put soldiers on the streets of the city because riots were spinning out of control is pure fantasy. “Today, demonstrations across the city of Los Angeles remained peaceful, and we commend all those who exercised their First Amendment rights responsibly,” said a statement issued by the Los Angeles Police Department on Saturday evening. That was the same day Trump overrode Gov. Gavin Newsom and federalized California’s National Guard, under a rarely used law meant to deal with “rebellion or danger of a rebellion against the authority of the government of the United States.”
Then, on Monday, with thousands of National Guard troops already deployed to the city, the administration said it was also sending 700 Marines. The Los Angeles police don’t seem to want the Marines there; in a statement, the police chief, Jim McDonnell, said, “The arrival of federal military forces in Los Angeles — absent clear coordination — presents a significant logistical and operational challenge for those of us charged with safeguarding this city.” But for Trump, safeguarding the city was never the point.
It’s important to understand that for this administration, protests needn’t be violent to be considered an illegitimate uprising. The presidential memorandum calling out the National Guard refers to both violent acts and any protests that “inhibit” law enforcement. That definition would seem to include peaceful demonstrations around the site of ICE raids. In May, for example, armed federal agents stormed two popular Italian restaurants in San Diego looking for undocumented workers; they handcuffed staff members and took four people into custody. As they did so, an outraged crowd gathered outside, chanting “shame” and for a time blocking the agents from leaving. Under Trump’s order, the military could target these people as insurrectionists.
Clearly Goldberg sees calling out both the National Guard and the Marines as a odious step towards an imposition of autocracy in America. I won’t comment on the above but ask readers to respond to the situation. Here are some questions:
1.) Should ICE (or whoever started arrested immigrants) have even gone after the people, even if they were undocumented immigrants who entered the country illegally?
2.) Should law enforcement wear masks?
3.) Is this an example of civil disobedience, violent protest, or both?
4.) Given the violence, was it still necessary (or even useful) to call out the National Guard?
5.) Should the Marines have been called out?
finally
6.) What would you do in this situation if you were President (or governor)?
Since psychic abilities do not exist outside the delusions of true believers, involving psychics in searches for missing persons is worse than useless.

JULY 15, 1979
I promised you a president who is not isolated from the people, who feels your pain, and who shares your dreams and who draws his strength and his wisdom from you.
During the past three years I’ve spoken to you on many occasions about national concerns, the energy crisis, reorganizing the government, our nation’s economy, and issues of war and especially peace. But over those years the subjects of the speeches, the talks, and the press conferences have become increasingly narrow, focused more and more on what the isolated world of Washington thinks is important. Gradually, you’ve heard more and more about what the government thinks or what the government should be doing and less and less about our nation’s hopes, our dreams, and our vision of the future.
It’s clear that the true problems of our Nation are much deeper—deeper than gasoline lines or energy shortages.Ten days ago, I had planned to speak to you again about a very important subject—energy. But as I was preparing to speak, I began to ask myself the same question that I now know has been troubling many of you. Why have we not been able to get together as a nation to resolve our serious energy problem?
It’s clear that the true problems of our Nation are much deeper—deeper than gasoline lines or energy shortages, deeper even than inflation or recession. And I realize more than ever that as president I need your help. So I decided to reach out and listen to the voices of America.
I invited to Camp David people from almost every segment of our society—business and labor, teachers and preachers, governors, mayors, and private citizens. And then I left Camp David to listen to other Americans, men and women like you.
It has been an extraordinary ten days, and I want to share with you what I’ve heard.
“Some of your Cabinet members don’t seem loyal. There is not enough discipline among your disciples.”
“Don’t talk to us about politics or the mechanics of government, but about an understanding of our common good.”
“Mr. President, we’re in trouble. Talk to us about blood and sweat and tears.”
Many people talked about themselves and about the condition of our nation.
This from a young woman in Pennsylvania: “I feel so far from government. I feel like ordinary people are excluded from political power.”
And this from a young Chicano: “Some of us have suffered from recession all our lives.”
This kind of summarized a lot of other statements: “Mr. President, we are confronted with a moral and a spiritual crisis.”
Several of our discussions were on energy, and I have a notebook full of comments and advice. I’ll read just a few.
“We can’t go on consuming 40 percent more energy than we produce. When we import oil we are also importing inflation plus unemployment.”
“We’ve got to use what we have. The Middle East has only five percent of the world’s energy, but the United States has 24 percent.”
And this is one of the most vivid statements: “Our neck is stretched over the fence and OPEC has a knife.”
“There will be other cartels and other shortages. American wisdom and courage right now can set a path to follow in the future.”
This was a good one: “Be bold, Mr. President. We may make mistakes, but we are ready to experiment.”
These ten days confirmed my belief in the decency and the strength and the wisdom of the American people, but it also bore out some of my long-standing concerns about our nation’s underlying problems.
Woman in graffiti-marked subway car, New York, May 1973 (Photo by Erik Calonius, U.S. National Archives and Records Administration)I know, of course, being president, that government actions and legislation can be very important. That’s why I’ve worked hard to put my campaign promises into law—and I have to admit, with just mixed success. But after listening to the American people I have been reminded again that all the legislation in the world can’t fix what’s wrong with America. So, I want to speak to you first tonight about a subject even more serious than energy or inflation. I want to talk to you right now about a fundamental threat to American democracy.
The erosion of our confidence in the future is threatening to destroy the social and the political fabric of America.I do not mean our political and civil liberties. They will endure. And I do not refer to the outward strength of America, a nation that is at peace tonight everywhere in the world, with unmatched economic power and military might.
The threat is nearly invisible in ordinary ways. It is a crisis of confidence. It is a crisis that strikes at the very heart and soul and spirit of our national will. We can see this crisis in the growing doubt about the meaning of our own lives and in the loss of a unity of purpose for our nation.
The erosion of our confidence in the future is threatening to destroy the social and the political fabric of America.
The confidence that we have always had as a people is not simply some romantic dream or a proverb in a dusty book that we read just on the Fourth of July.
It is the idea which founded our nation and has guided our development as a people. Confidence in the future has supported everything else—public institutions and private enterprise, our own families, and the very Constitution of the United States. Confidence has defined our course and has served as a link between generations. We’ve always believed in something called progress. We’ve always had a faith that the days of our children would be better than our own.
Human identity is no longer defined by what one does, but by what one owns.Our people are losing that faith, not only in government itself but in the ability as citizens to serve as the ultimate rulers and shapers of our democracy. As a people we know our past and we are proud of it. Our progress has been part of the living history of America, even the world. We always believed that we were part of a great movement of humanity itself called democracy, involved in the search for freedom, and that belief has always strengthened us in our purpose. But just as we are losing our confidence in the future, we are also beginning to close the door on our past.
In a nation that was proud of hard work, strong families, close-knit communities, and our faith in God, too many of us now tend to worship self-indulgence and consumption. Human identity is no longer defined by what one does, but by what one owns. But we’ve discovered that owning things and consuming things does not satisfy our longing for meaning. We’ve learned that piling up material goods cannot fill the emptiness of lives which have no confidence or purpose.
The symptoms of this crisis of the American spirit are all around us. For the first time in the history of our country a majority of our people believe that the next five years will be worse than the past five years. Two-thirds of our people do not even vote. The productivity of American workers is actually dropping, and the willingness of Americans to save for the future has fallen below that of all other people in the Western world.

Part of a propaganda campaign by the Council for Public Safety, a labor union representing police officers.As you know, there is a growing disrespect for government and for churches and for schools, the news media, and other institutions. This is not a message of happiness or reassurance, but it is the truth and it is a warning.
These changes did not happen overnight. They’ve come upon us gradually over the last generation, years that were filled with shocks and tragedy.
Washington, D.C., has become an island. The gap between our citizens and our government has never been so wide.We were sure that ours was a nation of the ballot, not the bullet, until the murders of John Kennedy and Robert Kennedy and Martin Luther King Jr. We were taught that our armies were always invincible and our causes were always just, only to suffer the agony of Vietnam. We respected the presidency as a place of honor until the shock of Watergate. We remember when the phrase “sound as a dollar” was an expression of absolute dependability, until ten years of inflation began to shrink our dollar and our savings. We believed that our nation’s resources were limitless until 1973, when we had to face a growing dependence on foreign oil.
These wounds are still very deep. They have never been healed. Looking for a way out of this crisis, our people have turned to the Federal government and found it isolated from the mainstream of our nation’s life. Washington, D.C., has become an island. The gap between our citizens and our government has never been so wide. The people are looking for honest answers, not easy answers; clear leadership, not false claims and evasiveness and politics as usual.
We simply must have faith in each other, faith in our ability to govern ourselves, and faith in the future of this nation.What you see too often in Washington and elsewhere around the country is a system of government that seems incapable of action. You see a Congress twisted and pulled in every direction by hundreds of well-financed and powerful special interests. You see every extreme position defended to the last vote, almost to the last breath by one unyielding group or another. You often see a balanced and a fair approach that demands sacrifice, a little sacrifice from everyone, abandoned like an orphan without support and without friends.
Often you see paralysis and stagnation and drift. You don’t like it, and neither do I. What can we do?
First of all, we must face the truth, and then we can change our course. We simply must have faith in each other, faith in our ability to govern ourselves, and faith in the future of this nation. Restoring that faith and that confidence to America is now the most important task we face. It is a true challenge of this generation of Americans.
Passengers ride spray-painted car in New York City, May 1973 (Photo by Erik Calonius, U.S. National Archives and Records Administration)We know the strength of America. We are strong. We can regain our unity. We can regain our confidence. We are the heirs of generations who survived threats much more powerful and awesome than those that challenge us now. Our fathers and mothers were strong men and women who shaped a new society during the Great Depression, who fought world wars, and who carved out a new charter of peace for the world.
We are at a turning point in our history. There are two paths to choose.We ourselves are the same Americans who just ten years ago put a man on the Moon. We are the generation that dedicated our society to the pursuit of human rights and equality. And we are the generation that will win the war on the energy problem and in that process rebuild the unity and confidence of America.
We are at a turning point in our history. There are two paths to choose. One is a path I’ve warned about tonight, the path that leads to fragmentation and self-interest. Down that road lies a mistaken idea of freedom, the right to grasp for ourselves some advantage over others. That path would be one of constant conflict between narrow interests ending in chaos and immobility. It is a certain route to failure.
All the traditions of our past, all the lessons of our heritage, all the promises of our future point to another path, the path of common purpose and the restoration of American values. That path leads to true freedom for our nation and ourselves. We can take the first steps down that path as we begin to solve our energy problem.
You see a Congress twisted and pulled in every direction by hundreds of well-financed and powerful special interests.Energy will be the immediate test of our ability to unite this nation, and it can also be the standard around which we rally. On the battlefield of energy we can win for our nation a new confidence, and we can seize control again of our common destiny.
In little more than two decades we’ve gone from a position of energy independence to one in which almost half the oil we use comes from foreign countries, at prices that are going through the roof. Our excessive dependence on OPEC has already taken a tremendous toll on our economy and our people. This is the direct cause of the long lines which have made millions of you spend aggravating hours waiting for gasoline. It’s a cause of the increased inflation and unemployment that we now face. This intolerable dependence on foreign oil threatens our economic independence and the very security of our nation. The energy crisis is real. It is worldwide. It is a clear and present danger to our nation. These are facts and we simply must face them.
You know we can do it. We have the natural resources. We have more oil in our shale alone than several Saudi Arabias. We have more coal than any nation on Earth. We have the world’s highest level of technology. We have the most skilled work force, with innovative genius, and I firmly believe that we have the national will to win this war.
I do not promise you that this struggle for freedom will be easy. I do not promise a quick way out of our nation’s problems, when the truth is that the only way out is an all-out effort. What I do promise you is that I will lead our fight, and I will enforce fairness in our struggle, and I will ensure honesty. And above all, I will act. We can manage the short-term shortages more effectively and we will, but there are no short-term solutions to our long-range problems. There is simply no way to avoid sacrifice.
The energy crisis is real. It is worldwide. It is a clear and present danger to our nation.Little by little we can and we must rebuild our confidence. We can spend until we empty our treasuries, and we may summon all the wonders of science. But we can succeed only if we tap our greatest resources—America’s people, America’s values, and America’s confidence.
I have seen the strength of America in the inexhaustible resources of our people. In the days to come, let us renew that strength in the struggle for an energy secure nation.
In closing, let me say this: I will do my best, but I will not do it alone. Let your voice be heard. Whenever you have a chance, say something good about our country. With God’s help and for the sake of our nation, it is time for us to join hands in America. Let us commit ourselves together to a rebirth of the American spirit. Working together with our common faith we cannot fail.
Thank you and good night.

Reader Kevin sent me this 4.5-minute video about two species of insects, earwigs and rove beetles, and how they fold their wings. It’s amazing, and I knew nothing about this. To quote Kevin:
Yesterday I saw this remarkable video on wing complexity in beetles and it really astonished me. Perhaps you’ve already seen it, but wanted to share it in case you haven’t. They guy has loads more great videos on his channel, too.
I sent the video to reader Robert Lang, among the very best origami experts in the world, thinking that he’d be interested in the folding. But of course he knew all about this (and more), for his folding knowledge and interests are wide, including designing a lens for a space telescope that can be folded up inside a rocket.
This all demonstrates Orgel’s Second Rule: “Evolution is cleverer than you are.” Natural selection sculpted these folds, presumably to allow a flying insect to scuttle through the leaf litter.
