There was an article on the website EarthSky News yesterday that, literally, took me out of this world. It described the role of magnetic rivers in newly forming star clusters.
There’s not a dog in sight but nevertheless I wanted to share this article with you.
Astronomers have learned that the pull of gravity can sometimes overcome the strong magnetic fields found in great star-forming clouds in space. The resulting weakly magnetized gas flow can feed the growth of new stars.
See the lines – called streamlines by scientists – in this composite image of the Serpens South star cluster? They’re from magnetic fields in this great star-forming cloud. Notice the lower left, where magnetic fields have been dragged into alignment with a narrow, dark filament. In that area, astronomers say, material from interstellar space is flowing into the star-forming cloud and fueling star formation. Image via NASA/ SOFIA/ T. Pillai/ JPL-Caltech/ L. Allen/ USRA.
Astronomers have known for decades that stars like our sun form when giant clouds of gas and dust in space – sometimes called molecular clouds – collapse under their own gravity. But how does the material from interstellar space flow into these clouds, and what controls the collapse? The image above helps illustrate an answer to these questions. It’s a composite, made with data from SOFIA – an airborne telescope designed for infrared astronomy – overlaid on an image from the now-retired Spitzer Space Telescope. This composite shows that the pull of gravity can sometimes overcome the strong magnetic fields found in great star-forming clouds in space. And it shows that, when that happens, weakly magnetized gas can flow – as on a conveyor belt – to feed the growth of newly forming star clusters.
A statement from the Max Planck Institute in Bonn, Germany, explained:
A major finding in the last decade has been that extensive networks of filaments permeate every molecular cloud. A picture has emerged that stars like our own sun form preferentially in dense clusters at the intersection of filaments.
Now look back at the image above, which shows the Serpens South star cluster, a star-forming region located some 1,400 light-years from Earth. In that image, you see a dark filament in the lower left. Now notice the “stripes” on the image, which astronomers call streamlines. They represent magnetic structures, discovered by SOFIA. The astronomers said these magnetic structures act like rivers, channeling material into the great star-forming cloud.
As you can see in the image, these magnetic streamlines have been dragged by gravity to align with the narrow, dark filament on the lower left. Astronomers say this configuration helps material from interstellar space flow into the cloud.
This is different from the upper parts of the image, where the magnetic fields are perpendicular to the filaments; in those regions, the magnetic fields in the cloud are opposing gravity.
Astrophysicist Thushara Pillai led the study showing that magnetic rivers feed star birth in the Serpens South star-forming region.
The scientists said in a statement from Universities Space Research Association (USRA) that they are:
… studying the dense cloud to learn how magnetic fields, gravity and turbulent gas motions contribute to the creation of stars. Once thought to slow star birth by counteracting gravity, SOFIA’s data reveals magnetic fields may actually be working together with gravity as it pulls the fields into alignment with the filaments, nourishing the birth of stars.
The results were published in the peer-reviewed journal Nature Astronomy on August 17. The lead author of the new study is Thushara Pillai of Boston University and the Max Planck Institute for Radio Astronomy in Bonn, Germany.
In 1835, the French philosopher Auguste Comte wrote of the unknowable nature of stars:
On the subject of stars, all investigations which are not ultimately reducible to simple visual observations are … necessarily denied to us. While we can conceive of the possibility of determining their shapes, their sizes, and their motions, we shall never be able by any means to study their chemical composition or their mineralogical structure … Our knowledge concerning their gaseous envelopes is necessarily limited to their existence, size … and refractive power, we shall not at all be able to determine their chemical composition or even their density…
He was, famously, wrong.
He couldn’t have envisioned the range of tools available to modern astronomers. It’s a beautiful thing that, nowadays, astronomers can not only learn about the compositions of stars via their studies of their spectra, but also probe the deeper mysteries, going all the way to the births of these colossal, self-luminous balls in space.

Bottom line: Astronomers have learned that the pull of gravity can sometimes overcome the strong magnetic fields found in great star-forming clouds in space. The resulting weakly magnetized gas flow can feed the growth of new stars.
Just read that paragraph just before the end of the article: “He couldn’t have envisioned the range of tools available to modern astronomers. It’s a beautiful thing that, nowadays, astronomers can not only learn about the compositions of stars via their studies of their spectra, but also probe the deeper mysteries, going all the way to the births of these colossal, self-luminous balls in space.”
What a long way we have come from just, say, 50 years ago.
It would be easy to get lost in the article in a scientific manner, and that would be entirely appropriate.
But there’s another beautiful way to get lost in the article; by dreaming of outer space and forgetting just for a moment or two this Earthly planet we all live on!
I was browsing the photographic forum Ugly Hedgehog the other day and saying thank you to some people who had said kind things about a few photographs I had shared. One person who had left a comment put in his signature block that he came from Adelaide, Australia. Part of my thank you was to inquire how things were in Adelaide.
Well blow me down when that person, Ron, came back to me and we then transferred to email and shared our backgrounds.
This is what Ron said in his first email:
Hi Paul,
You have had an interesting life over the years…
Love the Shepherd, we had one after we first got married..
Broke my heart so badly when he went I could never have another one.
I still think about him after all the years.
I retired at 55 years of age as I was with the government; I was a mechanical engineer with CSIRO designing new welding technologies along with many other projects over the years.
Sadly not the way I wanted to retire as my spinal injuries made it impossible to do the things I wanted to.
One of my biggest disappointments was having to give up my archery.
I’ve been doing photography for many and it has been a god send as it’s something I can still do.
We moved into a Lifestyle Village ( semi retirement) six and a half years ago as I was unable to look after the old house any more so I thought I’d let someone else worry about that..LOL
We try to get over to Sydney and Melbourne every year for a week or so but this year we missed out due to you know what.
Well, off to the shops now,
Cheers,
Ron.
And when I asked about the spinal injury, Ron added:
Hi Paul,
Hopefully you had no damage from your storm…
My spine, mostly my cervical spine, was damaged about 50 years ago in car stupidity.
I refuse to call it an accident.
I was sitting at a red light and a guy ran into my rear doing about 80-90 kilometers an hour without touching his brakes.
He was actually looking out of his side window!!
Over the years, and several operations and ongoing treatments, the pain got worse.
I’m now in pain all day every day.
At least the plates and screws keep things together.
Lorraine (wife) is my carer and when I get really bad, she gives me an injection of morphine mixed with some other “stuff”.
They discovered some years ago that my body doesn’t absorb oral meds very well.
My neurosurgeon then put me onto morphine.
Usually have one jab every two to three weeks.
At least I get one or two days of relief.
The rest of the time I just grin and bare it…LOL
I joined the Hog in 2012, November I think.
Sadly, my good friend, also a Hog, died earlier this year.
He lived in north NSW in a small coastal town called Maclean.
Say Hi to Jeannie for us.
Cheers,
Ron.
This is a photograph of Lorraine.
And this is a photograph of Harry.
And let me treat you with a few more photographs, some from “very old scanned film shots so not the best.”
oooo
oooo
oooo
oooo
But that’s a sharp reminder of the consequences of not paying attention to the road in front of you. All those years ago!
Dogs bring people together from all over the world!
We tend to watch many of the TED Talks that come our way.
But this one had me riveted to my seat. It’s a very powerful, nearly 9 minutes long, talk given by a person who doesn’t have legal citizenship.
Speaking on a personal basis, I was a person who went through the Citizenship test, successfully I might add, in March, 2019. So I watched this video with more than just academic interest.
See if you sense the feelings I had.
At age 16, journalist and filmmaker Jose Antonio Vargas found out he was in the United States illegally. Since then, he’s been thinking deeply about immigration and what it means to be a US citizen — whether it’s by birth, law or otherwise. In this powerful talk, Vargas calls for a shift in how we think about citizenship and encourages us all to reconsider our personal histories by answering three questions: Where did you come from? How did you get here? Who paid?
Jose Antonio Vargas, author of “Dear America: Notes of an Undocumented Citizen,” is the founder of Define American, a nonprofit organization that uses stories to shift the narrative on immigrants.
In the 10th July issue of Science magazine there was an Editorial written by Sudip Parikh, CEO of the American Association for the Advancement of Science (AAAS).
I am taking the liberty of republishing that Editorial here. For I think it needs to be widely shared.
I am a scientist. I am an American. And I am the product of special expert visas and chain migration—among the many types of legal immigration into the United States. On 22 June, President Trump issued a proclamation that temporarily restricts many types of legal immigration into the country, including that of scientists and students. This will make America neither greater nor safer—rather, it could make America less so.
The administration claims that these restrictions are necessitated by the coronavirus disease 2019 (COVID-19) outbreak to prevent threats to American workers. This reasoning is flawed for science and engineering, where immigrants are critical to achieving advances and harnessing the resulting economic opportunity for all Americans.
For decades, the United States has inspired both immigrants and nonimmigrants to make substantial contributions to science and technology that benefit everyone. Preventing highly skilled scientists and postdocs from entering the United States directly threatens this enterprise.
My uncle, a geologist, came to the United States in the 1960s to work at NASA. He then taught at Appalachian State University in North Carolina and later served as lead geochemist for the state of California. He sponsored my father to come to America in 1968. Leaving Mumbai, a city of millions, and arriving in Hickory, a town of thousands in North Carolina, my father came home to a place he had never been before. My parents worked in furniture factories and textile mills to put us though college and ensure we had opportunities. Today, my sister works at the U.S. Centers for Disease Control and Prevention, and I have the privilege of leading the American Association for the Advancement of Science (AAAS, the publisher of Science). We exist because of the Immigration and Nationality Act of 1965 and our parents’ belief in the vision of the United States as a shining city on a hill. My family’s story is repeated by thousands of American scientists.
These stories include uncertainty when an immigrant’s status in America is in question. This uncertainty causes stress and the possibility that immigrants will leave and take their skills, talents, and humanity elsewhere. For the successful, these stories culminate with relief, celebration, and the pride of becoming a naturalized citizen. As President Reagan said, the United States is the one place in the world where “anybody from any corner of the world can come…to live and become an American.” Naturalized citizens love the United States deeply because they chose to be American. They and other immigrants make huge contributions to science and engineering.
According to the National Science Foundation, more than 50% of postdocs and 28% of science and engineering faculty in the United States are immigrants. Of the Nobel Prizes in chemistry, medicine, and physics awarded to Americans since 2000, 38% were awarded to immigrants to the United States. I don’t know the number of prizes given to second-generation Americans but Steven Chu—current chair of the AAAS Board of Directors—is among them. The incredible achievements of the American scientific enterprise speak volumes about the vision and forethought of the American people who have worked to create a more perfect union.
Suspending legal immigration is self-defeating and breaks a model that is so successful that other nations are copying it. As Thomas Donohue, chief executive officer of the U.S. Chamber of Commerce, said regarding the administration’s proclamation, “Putting up a ‘not welcome’ sign for engineers, executives, IT experts, doctors, nurses, and other workers won’t help our country, it will hold us back. Restrictive changes to our nation’s immigration system will push investment and economic activity abroad, slow growth, and reduce job creation.”
To develop treatments and vaccines for COVID-19, cure cancers, go to Mars, understand the fundamental laws of the universe and human behavior, develop artificial intelligence, and build a better future, we need the brain power of the descendants of Native Americans, Pilgrims, Founding Mothers and Fathers, Enslaved People, Ellis Island arrivals, and immigrants from everywhere. The United States has thrived as a crossroads where people are joined together by ideas and contribute by choice to the freedom and opportunity provided by this wonderful, inspiring, and flawed country that is always striving to live up to its aspirations.
Scientists, look around your labs and offices. Think about your collaborations and friendships. We must ensure that this “temporary” restriction on legal immigration does not become permanent. Now is the time to speak up for your immigrant colleagues and for America.
Maybe because years ago he gave me blanket permission to republish his essays. Maybe because he and I are more or less the same age. Maybe because in my more quieter, introspective moments I wonder where the hell we are going. And Tom seems to agree.
Have a read of this.
ooOOoo

It Could Have Been Different
My World and (Unfortunately) Welcome to It
By Tom Engelhardt
Let me be blunt. This wasn’t the world I imagined for my denouement. Not faintly. Of course, I can’t claim I ever really imagined such a place. Who, in their youth, considers their death and the world that might accompany it, the one you might leave behind for younger generations? I’m 76 now. True, if I were lucky (or perhaps unlucky), I could live another 20 years and see yet a newer world born. But for the moment at least, it seems logical enough to consider this pandemic nightmare of a place as the country of my old age, the one that I and my generation (including a guy named Donald J. Trump) will pass on to our children and grandchildren.
Back in 2001, after the 9/11 attacks, I knew it was going to be bad. I felt it deep in my gut almost immediately and, because of that, stumbled into creating TomDispatch.com, the website I still run. But did I ever think it would be this bad? Not a chance.
I focused back then on what already looked to me like a nightmarish American imperial adventure to come, the response to the 9/11 attacks that the administration of President George W. Bush quickly launched under the rubric of “the Global War on Terror.” And that name (though the word “global” would soon be dropped for the more anodyne “war on terror”) would prove anything but inaccurate. After all, in those first post-9/11 moments, the top officials of that administration were thinking as globally as possible when it came to war. At the damaged Pentagon, Secretary of Defense Donald Rumsfeld almost immediately turned to an aide and told him, “Go massive — sweep it all up, things related and not.” From then on, the emphasis would always be on the more the merrier.
Bush’s top officials were eager to take out not just Osama bin Laden’s al-Qaeda, whose 19 mostly Saudi hijackers had indeed attacked this country in the most provocative manner possible (at a cost of only $400,000-$500,000), but the Taliban, too, which then controlled much of Afghanistan. And an invasion of that country was seen as but the initial step in a larger, deeply desired project reportedly meant to target more than 60 countries! Above all, George W. Bush and his top officials dreamed of taking down Iraqi autocrat Saddam Hussein, occupying his oil-rich land, and making the United States, already the unipolar power of the twenty-first century, the overseer of the Greater Middle East and, in the end, perhaps even of a global Pax Americana. Such was the oil-fueled imperial dreamscape of George W. Bush, Dick Cheney, Donald Rumsfeld, and crew (including that charmer and now bestselling anti-Trump author John Bolton).
Who Woulda Guessed?
In the years that followed, I would post endless TomDispatch pieces, often by ex-military men, focused on the ongoing nightmare of our country’s soon-to-become forever wars (without a “pax” in sight) and the dangers such spreading conflicts posed to our world and even to us. Still, did I imagine those wars coming home in quite this way? Police forces in American cities and towns thoroughly militarized right down to bayonets, MRAPs, night-vision goggles, and helicopters, thanks to a Pentagon program delivering equipment to police departments nationwide more or less directly off the battlefields of Washington’s never-ending wars? Not for a moment.
Who doesn’t remember those 2014 photos of what looked like an occupying army on the streets of Ferguson, Missouri, after the police killing of a Black teenager and the protests that followed? And keep in mind that, to this day, the Republican Senate and the Trump administration have shown not the slightest desire to rein in that Pentagon program to militarize police departments nationwide. Such equipment (and the mentality that goes with it) showed up strikingly on the streets of American cities and towns during the recent Black Lives Matter protests.
Even in 2014, however, I couldn’t have imagined federal agents by the hundreds, dressed as if for a forever-war battlefield, flooding onto those same streets (at least in cities run by Democratic mayors), ready to treat protesters as if they were indeed al-Qaeda (“VIOLENT ANTIFA ANARCHISTS”), or that it would all be part of an election ploy by a needy president. Not a chance.
Or put another way, a president with his own “goon squad” or “stormtroopers” outfitted to look as if they were shipping out for Afghanistan or Iraq but heading for Portland, Albuquerque, Chicago, Seattle, and other American cities? Give me a break! How un-American could you get? A military surveillance drone overhead in at least one of those cities as if this were someone else’s war zone? Give me a break again. Never in my wildest dreams did I think I’d live to witness anything quite like it or a president — and we’ve had a few doozies — even faintly like the man a minority of deeply disgruntled Americans but a majority of electors put in the White House in 2016 to preside over a failing empire.
How about an American president in the year 2020 as a straightforward, no-punches-pulled racist, the sort of guy a newspaper could compare to former segregationist Alabama governor and presidential candidate George Wallace without even blinking? Admittedly, in itself, presidential racism has hardly been unique to this moment in America, despite Joe Biden’s initial claim to the contrary. That couldn’t be the case in the country in which Woodrow Wilson made D.W. Griffith’s Birth of a Nation, the infamous silent movie in which the Ku Klux Klan rides to the rescue, the first film ever to be shown in the White House; nor the one in which Richard Nixon used his “Southern strategy” — Republican presidential candidate Barry Goldwater had earlier labeled it even more redolently “Operation Dixie” — to appeal to the racist fears of Southern whites and so begin to turn that region from a Democratic stronghold into a Republican bastion; nor in the land where Ronald Reagan launched his election campaign of 1980 with a “states’ rights” speech (then still a code phrase for segregation) near Philadelphia, Mississippi, just miles from the earthen dam where three murdered civil rights workers had been found buried in 1964.
Still, an openly racist president (don’t take that knee!) as an autocrat-in-the-making (or at least in-the-dreaming), one who first descended that Trump Tower escalator in 2015 denouncing Mexican “rapists,” ran for president rabidly on a Muslim ban, and for whom Black lives, including John Lewis’s, have always been immaterial, a president now defending every Confederate monument and military base named after a slave-owning general in sight, while trying to launch a Nixon-style “law and (dis)order” campaign? I mean, who woulda thunk it?
And add to that the once unimaginable: a man without an ounce of empathy in the White House, a figure focused only on himself and his electoral and pecuniary fate (and perhaps those of his billionaire confederates); a man filling his hated “deep state” with congressionally unapproved lackies, flacks, and ass-kissers, many of them previously flacks (aka lobbyists) for major corporations. (Note, by the way, that while The Donald has a distinctly autocratic urge, I don’t describe him as an incipient fascist because, as far as I can see, his sole desire — as in those now-disappeared rallies of his — is to have fans, not lead an actual social movement of any sort. Think of him as Mussolini right down to the look and style with a “base” of cheering MAGA chumps but no urge for an actual fascist movement to lead.)
And who ever imagined that an American president might actually bring up the possibility of delaying an election he fears losing, while denouncing mail-in ballots (“the scandal of our time”) as electoral fraud and doing his damnedest to undermine the Post Office which would deliver them amid an economic downturn that rivals the Great Depression? Who, before this moment, ever imagined that a president might consider refusing to leave the White House even if he did lose his reelection bid? Tell me this doesn’t qualify as something new under the American sun. True, it wasn’t Donald Trump who turned this country’s elections into 1% affairs or made contributions by the staggeringly wealthy and corporations a matter of free speech (thank you, Supreme Court!), but it is Donald Trump who is threatening, in his own unique way, to make elections themselves a thing of the past. And that, believe me, I didn’t count on.
Nor did I conceive of an all-American world of inequality almost beyond imagining. A country in which only the truly wealthy (think tax cuts) and the national security state (think budgets eternally in the stratosphere) are assured of generous funding in the worst of times.
The World to Come?
Oh, and I haven’t even mentioned the pandemic yet, have I? The one that should bring to mind the Black Death of the fourteenth century and the devastating Spanish Flu of a century ago, the one that’s killing Americans in remarkable numbers daily and going wild in this country, aided and abetted in every imaginable way (and some previously unimaginable ones) by the federal government and the president. Who could have dreamed of such a disease running riot, month after month, in the wealthiest, most powerful country on the planet without a national plan for dealing with it? Who could have dreamed of the planet’s most exceptional, indispensable country (as its leaders once loved to call it) being unable to take even the most modest steps to rein in Covid-19, thanks to a president, Republican governors, and Republican congressional representatives who consider science the equivalent of alien DNA? Honestly, who ever imagined such an American world? Think of it not as The Decameron, that fourteenth century tale of 10 people in flight from a pandemic, but the Trumpcameron or perhaps simply Trumpmageddon.
And keep in mind, when assessing this world I’m going to leave behind to those I hold near and dear, that Covid-19 is hardly the worst of it. Behind that pandemic, possibly even linked to it in complex ways, is something so much worse. Yes, the coronavirus and the president’s response to it may seem like the worst of all news as American deaths crest 160,000 with no end in sight, but it isn’t. Not faintly on a planet that’s being heated to the boiling point and whose most powerful country is now run by a crew of pyromaniacs.
It’s hard even to fully conceptualize climate change since it operates on a time scale that’s anything but human. Still, one way to think of it is as a slow-burn planetary version of the atomic bombings of Hiroshima and Nagasaki. And by the way, if you’ll excuse a brief digression, in these years, our president and his men have been intent on ripping up every Cold War nuclear pact in sight, while the tensions between two nuclear-armed powers, the U.S. and China, only intensify and Washington invests staggering sums in “modernizing” its nuclear arsenal. (I mean, how exactly do you “modernize” the already-achieved ability to put an almost instant end to the world as we’ve known it?)
But to return to climate change, remember that 2020 is already threatening to be the warmest year in recorded history, while the five hottest years so far occurred from 2015 to 2019. That should tell you something, no?
The never-ending release of greenhouse gases into the atmosphere has been transforming this planet in ways that have now become obvious. My own hometown, New York City, for instance, has officially become part of the humid subtropical climate zone and that’s only a beginning. Everywhere temperatures are rising. They hit 100 degrees this June in, of all places, Siberia. (The Arctic is warming at twice the rate of much of the rest of the planet.) Sea ice is melting fast, while floods and mega-droughts intensify and forests burn in a previously unknown fashion.
And as a recent heat wave across the Middle East — Baghdad hit a record 125 degrees — showed, it’s only going to get hotter. Much hotter and, given how humanity has handled the latest pandemic, how will it handle the chaos that goes with rising sea levels drowning coastlines but also affecting inland populations, ever fiercer storms, and flooding (in recent weeks, the summer monsoon has, for instance, put one third of Bangladesh underwater), not to speak of the migration of refugees from the hardest-hit areas? The answer is likely to be: not well.
And I could go on, but you get the point. This is not the world I either imagined or would ever have dreamed of leaving to those far younger than me. That the men (and they are largely men) who are essentially promoting the pandemicizing and over-heating of this planet will be the greatest criminals in history matters little.
Let’s just hope that, when it comes to creating a better world out of such a god-awful mess, the generations that follow us prove better at it than mine did. If I were a religious man, those would be my prayers.
And here’s my odd hope. As should be obvious from this piece, the recent past, when still the future, was surprisingly unimaginable. There’s no reason to believe that the future — the coming decades — will prove any easier to imagine. No matter the bad news of this moment, who knows what our world might really look like 20 years from now? I only hope, for the sake of my children and grandchildren, that it surprises us all.
This is such a powerful essay written from the heart of a good man.
I, too, wonder and worry about the next twenty years. Indeed, there are the stirrings of a book in my head. How that younger generation are reacting to the present and, more importantly, how they will react and respond to the next few years?
I’m 75 and really hope to live for quite a few more years. Jean is just a few years younger.
But much more importantly I have a son, Alex, who is 49, and a daughter, Maija, who is 48, and a grandson, Morten, of my daughter and her husband, who is 9.
With thanks to Monika for the title of today’s post!
My father was born in 1901. He had two wives. Me and my sister, Elizabeth, are the result of the relationship between our father and his second wife; Betty. Our father died in 1956; December 20th.
My father first was married to Maud and they had two daughters, Rhona and Corinne. Rhona died in 2003 and Corinne died in 2014. Although Rhona and Corinne were half-sisters I prefer to think of them as sisters!
Both had children. But I want to concentrate on Rhona. She and Reider, Norwegian by birth, had four children: Rolv; Greta; Rikard; Marit.
As is the way in this modern world, Rikky who lives near Torquay in South Devon, recently called in to see my brother-in-law, John, and John remarked to me that Rikky’s new wife, Jazz, was gorgeous. I asked Greta for a telephone number and, hey presto, Rikky and I were in contact with each other.
This is a little bit from Rik’s bio.
So you may remember I was with Amanda at the time of Mother’s passing, seems a long time ago now. Well that ultimately came to nothing and I ended up living alone with a couple of huskies in a small flat in Torquay. I had invested a large chunk of Mother’s inheritance into a PA system and set up and ran a sound engineering business for years as well as running quite a successful tribute band to ‘The Doors’. The PA company eventually ended after going into a partnership with a friend who also invested a chunk of cash allowing major upgrades to the kit.
Unfortunately I soon found out he was more interested in holidays to Spain than actual PA work, the problem being I had now sold vital parts of my rig which was replaced by his. We went separate ways and he took his gear with him leaving me without a full system, BIG lesson learnt.
At that point I went back to employment as an engineer for a company servicing and repairing lifting hoists to the health care industry. Four years in and the company went into administration.
Later Rikky says:
Back to work again this time to DPD as a delivery driver for a couple of years following in Rolv’s (Ed: brother) tyre tracks. This was when I also met Jazz on a random night out with friends. We immediately realised that we had many mutual friends and had actually met before many years ago when I was playing in her Dad’s Jazz band! This was around 19 years ago when I was 30 and Jazz was only 16. I only have a vague memory of her then sitting in a corner of the rehearsal room furiously scribbling in a sketch book.
Not much has changed there except she now holds a degree in Art and Design. She is also a Holistic Therapist and has trained in many holistic therapies including Reilki, Reflexology and Massage and is a very talented and beautiful woman. I feel incredibly blessed. She has two daughters Sanije and Latoja (nine and eleven) who I consider as mine; their father left the country last year and went back to Albania which actually has been a blessing for the girls as he is a difficult man to say the least.
So the driving job became another engineering position this time with a company specialising in fire alarms, a couple of years in and the contract I was working on was TUPED over to LiveWest which is one of the largest social housing companies in the South West. Two years after that and the company merged with another housing company, the role changed slightly so I was offered voluntary redundancy which I took giving me the financial opportunity to retrain as a commercial drone pilot and so here we are today.
We can accommodate all your aerial requirements from photography to cinematography, inspections to 3d mapping.
The name of Rik’s website is Ahead4Heights which strikes me as apt. And from the About page of that website, one reads:
Here at Ahead4Heights we have a passion for flying drones and creating visually stunning aerial films and photography. We are PfCO certified by the Civil Aviation Authority and hold full public liability insurance giving you complete confidence in us to provide the service you require.
With our post production studio facility we are able to add voice overs and original music written to your brief if required as we have our own in house composer and audio recording engineer.
Our UAV fleet consists of a variety of drones from the market leading DJI Inspire 2, capable of filming in incredible 5.2k resolution and producing the RAW file format standard for the film industry to our Pixhawk based quadcopter (equipt with a 4k camera) which we use for autonomous flight taking photos used to generate 3d mapping of locations useful for the construction industry.
Finally we have a heavy lift Tarot 680 hexacopter which is used as a backup drone and also for specialised payloads such as thermal cameras and high power lighting.
If you simply want aerial photos for property sales, photos and footage for weddings and events we will be happy to offer our services to you.
We can also carry out inspection work on roofs, tower masts and bridges etc where specialised safety equipment and scaffolding would otherwise be required. Utilizing both the high resolution and thermal imaging cameras we are able to identify problems with the insulation of properties, stress points in structures and damage to roofs and guttering.
Ahead4Heights also holds certificates in the building and setting up of drones so if you require a drone built to your special requirements we would be happy to discuss. We would also offer a full maintenance package with any build projects.
A couple more photographs.
oooo
And, of course, one more of the dogs! That is Storm and Tia.
A fascinating journey about our Sun (and welcome Bruce).
The sun gives us everything. It is life!
I don’t know about you but there is something beautiful, something therapeutic, about thinking about stuff outside the day-to-day run of things. I came across this video recently, luckily on YouTube so I can share it with you. It is about the sun.
Here’s the introduction to the video:
The Copernican Principle has been with us for centuries. It broadly states that “we are typical” but increasingly we are beginning to question this doctrine. One famous push back is the Rare Earth hypothesis, but testing this idea will take generations. What about our Sun? Surely here we should have a better understanding as to whether our star is typical or not.
Join us as we discuss why the Sun might be more special than Copernicus ever imagined. Written and presented by Prof Kipping, this video is based on research conducted at the Cool Worlds Lab at Columbia University, New York.
The video starts immediately with some outstanding statements and one is drawn straightaway into Professor Kipping’s voice. The voyage is fantastic and truly out of this world.
Here it is:
It makes for a most intriguing thought about our planet and how we are, or are not, caring for it.
I wrote in my post of the 23rd: “In fact tomorrow I shall republish a post I wrote in 2015 about the origins of the dog!”
Well tomorrow wasn’t possible with the sad news of the loss of our cat.
But it is today! It was originally published on the 13th July, 2015 – my how 5 years have sped by!
So here it is again. I suspect many of you have not read it!

The Origins of the Dog.
Dogs and humans go back even further than previously thought.
Humans and dogs were constant companions well before our ancestors settled in villages and started growing crops 10,000 years ago …
I have no doubt that thousands of dog owners all around the world must be enthralled by the way that dogs relate to us and, in turn, how we humans relate to dogs. More than once a day, one of our dogs will do something that has me and Jean marvelling at their way of living so close to us.
Then when one starts to reflect on how long dogs and humans have been together, perhaps it could be seen as the direct result of that length of relationship.
Now there’s nothing new in me writing this, after all the home page of Learning from Dogs states:
Yet they have been part of man’s world for an unimaginable time, at least 30,000 years. That makes the domesticated dog the longest animal companion to man, by far!
Back in May the website Livescience published an article that revealed more about the length of our relationship with dogs. This is how it opened:
Ancient Wolf DNA Could Solve Dog Origin Mystery
by Becky Oskin, Senior Writer
Humans and dogs were constant companions well before our ancestors settled in villages and started growing crops 10,000 years ago, a new study suggests.
Genetic evidence from an ancient wolf bone discovered lying on the tundra in Siberia’s Taimyr Peninsula reveals that wolves and dogs split from their common ancestor at least 27,000 years ago. “Although separation isn’t the same as domestication, this opens up the possibility that domestication occurred much earlier than we thought before,” said lead study author Pontus Skoglund, who studies ancient DNA at Harvard Medical School and the Broad Institute in Massachusetts. Previously, scientists had pegged the wolf-dog split at no earlier than 16,000 years ago.
The Livescience article referred to results that were published in the journal Current Biology on May 21st this year. One needs a subscription to read the full report but here is their summary:
The origin of domestic dogs is poorly understood [ 1–15 ], with suggested evidence of dog-like features in fossils that predate the Last Glacial Maximum [ 6, 9, 10, 14, 16 ] conflicting with genetic estimates of a more recent divergence between dogs and worldwide wolf populations [ 13, 15, 17–19 ]. Here, we present a draft genome sequence from a 35,000-year-old wolf from the Taimyr Peninsula in northern Siberia. We find that this individual belonged to a population that diverged from the common ancestor of present-day wolves and dogs very close in time to the appearance of the domestic dog lineage. We use the directly dated ancient wolf genome to recalibrate the molecular timescale of wolves and dogs and find that the mutation rate is substantially slower than assumed by most previous studies, suggesting that the ancestors of dogs were separated from present-day wolves before the Last Glacial Maximum. We also find evidence of introgression from the archaic Taimyr wolf lineage into present-day dog breeds from northeast Siberia and Greenland, contributing between 1.4% and 27.3% of their ancestry. This demonstrates that the ancestry of present-day dogs is derived from multiple regional wolf populations.
That summary page also includes the following Graphical Abstract:
I don’t have permission to republish the Livescience article in full but would like to offer the closing paragraphs of this fascinating report.
“It is a very well-done paper,” Perry [George Perry, an expert in ancient DNA at Pennsylvania State University] told Live Science. “This topic is a critical one for our understanding of human evolution and human-environment interactions in the Paleolithic. Partnership with early dogs may have facilitated more efficient hunting strategies.”
If dogs first befriended hunter-gatherers, rather than farmers, then perhaps the animals helped with hunting or keeping other carnivores away. For instance, an author of a new book claims humans and dogs teamed up to drive Neanderthals to extinction. Skoglund also suggested the Siberian husky followed nomads across the Bering Land Bridge, picking up wolf DNA along the way.
“It might have been beneficial for them to absorb genes that were adapted to this high Arctic environment,” Skoglund said.
This is the first wolf genome from the Pleistocene, and more ancient DNA from prehistoric fossils could provide further insights into the relationship between wolves, dogs and humans, the researchers said.
Yes, our dogs have been part of man’s world for an unimaginable time – and Jean and I, as with tens of thousands of others, can’t imagine a world without dogs.
ooOOoo
They are our supreme companions. They don’t judge. They don’t lie. They are …. well let me repeat what I wrote right at the beginning of the blog.
Dogs are part of the Canidae, a family including wolves, coyotes and foxes, thought to have evolved 60 million years ago. There is no hard evidence about when dogs and man came together but dogs were certainly around when man developed speech and set out from Africa, about 50,000 years ago. See an interesting article by Dr. George Johnson.
Because of this closeness between dogs and man, we (as in man!) have the ability to observe the way they live. Now I’m sure that scientists would cringe with the idea that the way that a dog lives his life sets an example for us humans, well cringe in the scientific sense. But man seems to be at one of those defining stages in mankind’s evolution where the forces bearing down on the species homo sapiens have the potential to cause very great harm. If the example of dogs can provide a beacon of hope, an incentive to change at a deep cultural level, then the quicker we ‘get the message’, the better it will be.
A very interesting article in Scientific American magazine!
A single page article in this month’s Scientific American magazine is fascinating. The sub-heading is: “An amicable disposition also governed the course of evolution for an animal that turned into a favorite pet.”
A little later on in the article one reads:
When our research group began its work almost 20 years ago, we discovered that dogs also have extraordinary intelligence: they can read our gestures better that any other species, even bonobos and chimpanzees. Wolves, in contrast, are mysterious and unpredictable. Their home is the wilderness, and that wilderness is shrinking.
The article was written by Prof. Brian Hare and Vanessa Woods and is part of a much longer piece on Homo sapiens.
In fact tomorrow I shall republish a post I wrote in 2015 about the origins of the dog!
The Moon is an astronomical body orbitingEarth and is the planet’s only natural satellite. It is the fifth-largest satellite in the Solar System, and by far[13] the largest among planetary satellites relative to the size of the planet that it orbits (its primary). The Moon is, after Jupiter‘s satellite Io, the second-densest satellite in the Solar System among those whose densities are known.
The Moon is thought to have formed about 4.51 billion years ago, not long after Earth. The most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a hypothetical Mars-sized body called Theia. New research of Moon rocks, although not rejecting the Theia hypothesis, suggests that the Moon may be older than previously thought.[14]
The Moon is in synchronous rotation with Earth, and thus always shows the same side to Earth, the near side. Because of libration, slightly more than half (about 59%) of the total lunar surface can be viewed from Earth.[15] The near side is marked by dark volcanic maria that fill the spaces between the bright ancient crustal highlands and the prominent impact craters. After the Sun, the Moon is the second-brightest celestial object regularly visible in Earth’s sky. Its surface is actually dark, although compared to the night sky it appears very bright, with a reflectance just slightly higher than that of worn asphalt. Its gravitational influence produces the ocean tides, body tides, and the slight lengthening of the day.
The Moon’s average orbital distance is 384,402 km (238,856 mi),[16][17] or 1.28 light-seconds. This is about thirty times the diameter of Earth. The Moon’s apparent size in the sky is almost the same as that of the Sun, since the star is about 400 times the lunar distance and diameter. Therefore, the Moon covers the Sun nearly precisely during a total solar eclipse. This matching of apparent visual size will not continue in the far future because the Moon’s distance from Earth is gradually increasing.
Venus is the second planet from the Sun. It is named after the Roman goddess of love and beauty. As the second-brightest natural object in the night sky after the Moon, Venus can cast shadows and can be, on rare occasion, visible to the naked eye in broad daylight.[15][16] Venus lies within Earth’s orbit, and so never appears to venture far from the Sun, either setting in the west just after dusk or rising in the east a bit before dawn. Venus orbits the Sun every 224.7 Earth days.[17] With a rotation period of 243 Earth days, it takes longer to rotate about its axis than any other planet in the Solar System and does so in the opposite direction to all but Uranus (meaning the Sun rises in the west and sets in the east).[18] Venus does not have any moons, a distinction it shares only with Mercury among planets in the Solar System.[19]
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet’s surface is 92 times that of Earth, or roughly the pressure found 900 m (3,000 ft) underwater on Earth. Venus is by far the hottest planet in the Solar System, with a mean surface temperature of 737 K (464 °C; 867 °F), even though Mercury is closer to the Sun. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had water oceans in the past,[20][21] but these would have vaporized as the temperature rose due to a runaway greenhouse effect.[22] The water has probably photodissociated, and the free hydrogen has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.[23] Venus’s surface is a dry desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
As one of the brightest objects in the sky, Venus has been a major fixture in human culture for as long as records have existed. It has been made sacred to gods of many cultures, and has been a prime inspiration for writers and poets as the morning star and evening star. Venus was the first planet to have its motions plotted across the sky, as early as the second millennium BC.[24]
I included these excerpts from WikiPedia because many will find them of interest and quite a few, including yours truly, actually learnt something!
I can’t remember how long ago it was that I came across Alexandra Horowitz but the name stuck. For Alexandra is an author of many titles although many of them are about dogs.
But here’s a quote from someone who reviewed her book, On Looking: A Walker’s Guide to the Art of Observation.
“Horowitz writes like a poet, thinks like a scientist, and ventures like an explorer. Her book will have you looking in a new way at the world around you, and make you glad you did.” – Susan Orlean, author of Rin Tin Tin
If you haven’t already read some of her books then don’t delay!
Now I want to introduce a different side of Alexandra. That of her being a broadcaster, for want of a better description.
This is not a short video, it is 49 minutes long. But that’s a reason to sit down and thoroughly immerse oneself in her talk.
It is introduced thus:
To a dog, there is no such thing as “fresh air.” Every breath is full of information—in fact, what every dog knows about the world comes mostly through their nose. Dogs, when trained, can identify drugs of every type, underwater cadavers, cancer, illicit cell phones in prison, bed bugs, smuggled shark fins, dry rot, land-mines, termites, invasive knapweed, underground truffles, and dairy cows in estrous. But they also know about the upcoming weather, earthquakes before they happen, how “afternoon” smells, what you had for breakfast, and whether a cat touched your leg yesterday. And of course, they sniff their way home and know the distinctive odor of each spot of sidewalk as you travel there.
Alexandra Horowitz is a research scientist in the field of dog cognition and the New York Times bestselling author of “Inside of a Dog”. Her new book “BEING A DOG: Following the Dog into a World of Smell” explores in even greater depth what dogs know, delving into all of these remarkable abilities and revealing a whole world of experiences we miss every day. Alexandra visited Google Seattle to share her research and open eyes (and noses!) of pet parents everywhere.
