Stanley Baldwin statue, Bewdley, 15th July 2025
165/365: Stanley Baldwin statue, Bewdley
Click for a larger, sharper image

I fear that today's revelations about 7,000 Afghans being relocated to Britain, but this being covered up for three years by successive governments, make it even more likely that Reform will win the next election. Superinjunctions are enormously unpopular (deservedly so) and immigration has become a major wedge issue in Westminster politics. Both the Tories and Labour will suffer politically for this, all the more so as parts of the (original, non-super) injunction remain in force. There's also the underlying data security issue, in that (it's been at least suggested) personal data of these Afghans was kept in a simple Excel file. That's absurdly bad practice for something as sensitive as this. As I've seen elsewhere, maybe this was a reason Ben Wallace (then Defence Secretary) refused to stand for Tory leader after Boris Johnson's exit. He'd probably have won -- but maybe he didn't want to be PM when this came out.

Embarrassingly, much of the media is not leading on that but on John Torode's "sacking" (actually contract non-renewal) from Masterchef. The BBC says it relates to "an extremely offensive racist term" being used in the workplace -- not specified, but I'm sure we're all thinking of the same word here. Torode says he can't remember the event. Myself? If he did use that word then it's clearly unacceptable -- but I still confess to being pretty uncomfortable with one stupid remark, eight years ago, which other people around for apparently didn't see as malicious, having these consequences. It's not "cancel culture" exactly, but I'm not sure anyone will have gone eight years without saying something out of line, even if not this kind of out of line. I do have to wonder if this is all there is to the Torode story. But we may see.

Then we have the 12-year-old girl prevented from giving a speech on a school's culture day when she wore a Geri Halliwell-style Union Flag dress (in a more school-and-age appropriate design). The school's apology and statement, reported in the Guardian article linked to, is boilerplate waffle and so it's hard to tell what actually happened. If the girl was prevented from talking about British culture purely because it was British then that wasn't fair. I don't think it's analagous to the old "But where's Straight Pride Day?" whines, not really. Now, if there were other factors -- some of which may not be reportable due to privacy, safeguarding etc -- then there may be more to it. The father's Facebook post, also in the article, can be read in various ways. But I'm absolutely certain Reform will make hay with it.

Anyway, talking of British culture, have that rare thing these days -- a relatively new statue of a British politician! Stanley Baldwin, three times Prime Minister, was born in Bewdley in 1867. Various local groups including the Civic Society had wanted a statue in the town centre for decades, but it was only finally unveiled a few years ago. As far as I can tell, it hasn't caused any controversy at all.

NASA's New Horizons spacecraft got a fleeting glimpse of Pluto 10 years ago, revealing a distant world with a picturesque landscape that, paradoxically, appears to be refreshing itself in the cold depths of our Solar System.

The mission answered numerous questions about Pluto that have lingered since its discovery by astronomer Clyde Tombaugh in 1930. As is often the case with planetary exploration, the results from New Horizons' flyby of Pluto on July 14, 2015, posed countless more questions. First and foremost, how did such a dynamic world come to be so far from the Sun?

For at least the next few decades, the only resources available for scientists to try to answer these questions will be either the New Horizons mission's archive of more than 50 gigabits of data recorded during the flyby, or observations from billions of miles away with powerful telescopes on the ground or space-based observatories like Hubble and James Webb.

Perry Barr Stadium, 14th July 2025
164/365: Perry Barr Greyhound Stadium, Birmingham
Click for a larger, sharper image

I couldn't resist that subject line! What you see here is the very last weeks of Perry Barr Stadium in Birmingham, mostly known as a greyhound track. I have little time for greyhound racing, and I suspect the decision to amalgamate both this and Monmore Green in Wolverhampton on a new site at Dunstall Park (already a horse racing track) elsewhere in Wolverhampton only puts off the inevitable for a few years. The sport is in steep and probably irreversible decline and the days when the Greyhound Derby at White City, London attracted 92,000 fans, and the sport was beaten only by football for total attendances in some years, are long past. As I say, I'm not keen on greyhound racing itself. I'm more saddened by the fact that the Birmingham Brummies, the speedway team who race here, will go out of business altogether when the stadium is closed next month to be redeveloped for housing.

Greyhound racing is on its way out for several reasons. First among them is concern for animal welfare, more so than with horse racing. The sport is also almost totally dependent these days on internet betting, which means both tiny crowds (in the hundreds) and a nearly impossible task in attracting new blood in the shape of families. The format of greyhound racing means short races with long gaps, and there's far less peripheral entertainment (food, bouncy castles, etc) than at horse racing courses. Regardless of the Dunstall Green move, even without England following Wales' imminent ban¹ I suspect greyhound racing will effectively die in Britain in the next decade. Most people, including me, are unlikely to mourn it -- but the stadium is a part of Birmingham's sporting and social history, so I thought it worth documenting before it disappears entirely.
¹ This is largely symbolic, as only one Welsh track remains anyway.

I was mostly in Perry Barr for boring reasons unconnected with the stadium, but I will note that the suburb is also home to the far more successful Alexander Stadium, the biggest athletics venue in the UK (capacity 18,000) and the host for the athletics competitions in the 2022 Commonwealth Games. The other notable feature is a medium-sized shopping centre, which has fewer closed units than some (though certainly not none) and boasts a quite decent Wetherspoons, the Arthur Robertson. The pub is named after the first member of local athletics club Birchfield Harriers (still in existence) to win an Olympic event, when he took gold in the three-mile run at the 1908 Games in London. The still-continuing bin strike was sadly obvious in the startling amount of litter on the verges, though oddly a few streets away (still in Birmingham) things were a lot less unpleasant. Still, Perry Barr could really do with some proper community-centric redevelopment. We'll see.

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new black hole that is 225 times more massive than our Sun. The results were presented at the Edoardo Amaldi Conference on Gravitational Waves in Glasgow, Scotland.

The LIGO/Virgo/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. LIGO detects gravitational waves via laser interferometry, using high-powered lasers to measure tiny changes in the distance between two objects positioned kilometers apart. LIGO has detectors in Hanford, Washington, and in Livingston, Louisiana. A third detector in Italy, Advanced Virgo, came online in 2016. In Japan, KAGRA is the first gravitational-wave detector in Asia and the first to be built underground. Construction began on LIGO-India in 2021, and physicists expect it will turn on sometime after 2025.

To date, the collaboration has detected dozens of merger events since its first Nobel Prize-winning discovery. Early detected mergers involved either two black holes or two neutron stars.  In 2021, LIGO/Virgo/KAGRA confirmed the detection of two separate "mixed" mergers between black holes and neutron stars.

Holding Pens, Bewdley, 13th July 2025
163/365: The Holding Pens, Bewdley
Click for a larger, sharper image

My cheery historical reading today has been on the ancient Neo-Assyrians of around 700 BC, who -- it turns out -- were absolutely detested for their apparent revelry in cruelty. They not only went in for flaying alive, impalement and much more besides, but unlike other harsh empires they made a point of depicting the atrocities on their monuments as a way of ruling by fear and terror. They called this "calculated frightfulness", and they were hated for this even by other civilisations in that violent age. From what I've gathered, which is inevitably partial (in both senses) this contributed to their downfall, with some other rivalries suspended for a joint assault on the Assyrians.

Meanwhile, back in the modern world, it was a mere 28 °C today. I still had an ice cream, though (orange and dark chocolate flavour) and was very glad to get it. Today's 365 photo comes from Wribbenhall (the part of Bewdley on the eastern bank of the River Severn), very close to the Severn Valley Railway viaduct -- in fact, that's just about visible in the extreme top left. This is what's left of the Holding Pens. Before the railway arrived in the 1860s, there was a butcher's shop close by, and this is where animals were kept before slaughter. The more regular of the holes you can see in the sandstone are artificial, and once held fence posts and the like.

The Curiosity rover was sent up the Mount Sharp, the biggest sediments stack on Mars. On the way, it collected samples that indicated a portion of carbon dioxide in the Martian atmosphere might have been sequestered in the sedimentary rocks, just as it happens with limestone on Earth. This would have drawn carbon dioxide out of the atmosphere, reducing the greenhouse effect that warmed the planet.

Based on these findings, a team of scientists led by Benjamin Tutolo, a researcher at the University of Calgary, used this data to conclude Mars had a carbon cycle that could explain the presence of liquid water on its surface. Building on that earlier work, a team led by Edwin Kite, a professor of planetary science at the University of Chicago (and member of the Curiosity science team) has now built the first Martian climate model that took these new results into account. The model also included Martian topography, the luminosity of the Sun, latest orbital data, and many other factors to predict how the Martian conditions and landscape evolved over the span of 3.5 billion years.

Their results mean that any Martian life would have had a rough time of it.

Worcester Engine Works, 12th July 2025
162/365: Worcester Engine Works
Click for a larger, sharper image

It was a mere 32 °C today. I was in Worcester, and it was still fiercely hot in the unbroken afternoon sunshine. Today's photo subject will be a familiar sight to those who know Worcester, as it's very close to Shrub Hill station. This imposing (if rather neglected) structure is the Worcester Engine Works. The company of that name existed for under a decade, having been set up in 1864 as a reaction to the Great Western Railway moving its carriage works from Worcester to Swindon after a fire. The Worcester company did well initially, but it faltered during the Panic of 1866 and never really recovered, going into liquidation a few years later. In recent years the Works building has rather struggled to find a role: its Grade II listed status restricts how much alteration can be made, and mostly it's been occupied by a succession of small commercial offices.

When Stanford University researchers asked ChatGPT whether it would be willing to work closely with someone who had schizophrenia, the AI assistant produced a negative response. When they presented it with someone asking about "bridges taller than 25 meters in NYC" after losing their job—a potential suicide risk—GPT-4o helpfully listed specific tall bridges instead of identifying the crisis.

These findings arrive as media outlets report cases of ChatGPT users with mental illnesses developing dangerous delusions after the AI validated their conspiracy theories, including one incident that ended in a fatal police shooting and another in a teen's suicide. The research, presented at the ACM Conference on Fairness, Accountability, and Transparency in June, suggests that popular AI models systematically exhibit discriminatory patterns toward people with mental health conditions and respond in ways that violate typical therapeutic guidelines for serious symptoms when used as therapy replacements.

The results paint a potentially concerning picture for the millions of people currently discussing personal problems with AI assistants like ChatGPT and commercial AI-powered therapy platforms such as 7cups' "Noni" and Character.ai's "Therapist."

Hottest day of the year, Bewdley, 11th July 2025
161/365: Hottest day of the year, outskirts of Bewdley
Click for a larger, sharper image

As the subject line says, it was indeed 34 °C here today, and Astwood Bank elsewhere in Worcestershire seems to have taken the daily record at 34.7 °C. Looking quickly back, I think the temperature I recorded makes it the third hottest day where I am since I started keeping notice over 20 years ago. Only 18th and 19th July 2022 beat it, and then only by one degree. Certainly it felt unpleasantly hot when I briefly ventured outdoors. Tomorrow looks like being very similar, perhaps only a degree or two cooler at best. That said, it's probably the lack of rain that's bothering people more, especially farmers. You can see pretty well why that is in the photo. That grass is not often this yellow even at the height of summer. It certainly wasn't with all the rain last year!

Welcome to Edition 8.02 of the Rocket Report! It's worth taking a moment to recognize an important anniversary in the history of human spaceflight next week. Fifty years ago, on July 15, 1975, NASA launched a three-man crew on an Apollo spacecraft from Florida and two Russian cosmonauts took off from Kazakhstan, on course to link up in low-Earth orbit two days later. This was the first joint US-Russian human spaceflight mission, laying the foundation for a strained but enduring partnership on the International Space Station. Operations on the ISS are due to wind down in 2030, and the two nations have no serious prospects to continue any partnership in space after decommissioning the station.

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Sizing up Europe's launch challengers. The European Space Agency has selected five launch startups to become eligible for up to 169 million euros ($198 million) in funding to develop alternatives to Arianespace, the continent's incumbent launch service provider, Ars reports. The five small launch companies ESA selected are Isar Aerospace, MaiaSpace, Rocket Factory Augsburg, PLD Space, and Orbex. Only one of these companies, Isar Aerospace, has attempted to launch a rocket into orbit. Isar's Spectrum rocket failed moments after liftoff from Norway on a test flight in March. None of these companies is guaranteed an ESA contract or funding. Over the next several months, ESA and the five launch companies will negotiate with European governments for funding leading up to ESA's ministerial council meeting in November, when ESA member states will set the agency's budget for at least the next two years. Only then will ESA be ready to sign binding agreements.

“We were getting basil leaves the size of your palm,” University of Arizona researcher Greg Barron-Gafford said, describing some of the benefits he and his team have seen farming under solar panels in the Tucson desert.

For 12 years, Barron-Gafford has been investigating agrivoltaics, the integration of solar arrays into working farmland. This practice involves growing crops or other vegetation, such as pollinator-friendly plants, under solar panels, and sometimes grazing livestock in this greenery. Though a relatively new concept, at least 604 agrivoltaic sites have popped up across the United States, according to OpenEI.

Russia is a waning space power, but President Vladimir Putin has made sure he still has a saber to rattle in orbit.

This has become more evident in recent weeks, when we saw a pair of rocket launches carrying top-secret military payloads, the release of a mysterious object from a Russian mothership in orbit, and a sequence of complex formation-flying maneuvers with a trio of satellites nearly 400 miles up.

In isolation, each of these things would catch the attention of Western analysts. Taken together, the frenzy of maneuvers represents one of the most significant surges in Russian military space activity since the end of the Cold War. What's more, all of this is happening as Russia lags further behind the United States and China in everything from rockets to satellite manufacturing. Russian efforts to develop a reusable rocket, field a new human-rated spacecraft to replace the venerable Soyuz, and launch a megaconstellation akin to SpaceX's Starlink are going nowhere fast.

Ducks in Dog Lane, Bewdley, 10th July 2025
160/365: Toy ducks, Bewdley
Click for a larger, sharper image

An even warmer day today (Thursday). My highest reading was 31 °C, which is the equal hottest day of the year for me. There's a strong chance that Friday will beat this mark. I needed to go down to Sainsbury's in town for a couple of things, so I made sure to do that well before nine. On the way I found these amusing toy ducks in Dog Lane, not far from Sainsbury's. The road name's etymology is not certain, but it may be a corruption of "Duck Lane", since the road runs down to the river and the town's ducking stool may have been situated there centuries ago. The residents of this house have given that possible earlier name a much cuter interpretation in their tiny front yard!

Our discussion with Zeke Hausfather. Click here for transcript.

In late June, we hosted this year's second Ars Live event, a conversation with climate scientist Zeke Hausfather, who holds positions with the financial services company Stripe and at the Berkeley Earth Project, which tracks the global surface temperatures. We wanted to get his perspective on why those temperatures have been setting extreme records with regularity of late, but we took a little detour on the way, asking how he ended up doing climate science in the first place.

It turned out to be a very indirect route. He'd been a climate activist during his college years and helped launch a couple of cleantech startups afterward. At the time, some of the first academic climate bloggers were getting started, and Hausfather found himself doing small projects with them. Over time, he decided "my hobby was more fun than my day job," so he decided to take time off from the business world and get a PhD in climate science. From there, he has kept his feet in both the climate and business worlds.

The conversation then moved to the record we have of the Earth's surface temperatures and the role of Berkeley Earth in providing an alternate method of calculating those. While the temperature records were somewhat controversial in the past, those arguments have largely settled down, and Berkeley Earth played a major role in helping to show that the temperature records have been reliable.

James McCully was in the lab extracting tiny structures called mitochondria from cells when researchers on his team rushed in. They’d been operating on a pig heart and couldn’t get it pumping normally again.

McCully studies heart damage prevention at Boston Children’s Hospital and Harvard Medical School and was keenly interested in mitochondria. These power-producing organelles are particularly important for organs like the heart that have high energy needs. McCully had been wondering whether transplanting healthy mitochondria into injured hearts might help restore their function.

The pig’s heart was graying rapidly, so McCully decided to try it. He loaded a syringe with the extracted mitochondria and injected them directly into the heart. Before his eyes, it began beating normally, returning to its rosy hue.

Ukrainian APC, Kidderminster, 10th July 2025
159/365: Armoured personnel carrier on back of lorry, Kidderminster
Click for a larger, sharper image

Another very warm day. I saw this armoured personnel carrier on the back of a lorry in Kidderminster today. If you look carefully, you can see a Ukrainian flag near the front (left) of the vehicle. I'm afraid I know very little about military vehicles, so I can't tell you what model it is or anything. I have absolutely no idea what this thing was doing in Kidderminster at all, let alone this particular road; this area is a boring stretch of offices, commercial warehouses and the like with no obvious military relevance. I suppose it could be being repaired, but why here? You can't see the number plate in the photo, but I did check something: the lorry carrying it has an ordinary UK civilian number plate.
