In recent years, nutrition has become the focus of renewed attention in medical education. Advocates argue that physicians receive too little formal training about diet and that more comprehensive nutrition education is needed to address chronic diseases such as obesity, diabetes, cardiovascular disease, and certain cancers. A greater focus on the “root causes of chronic diseases” is a mantra of the Make […]

Scientists may have found a powerful new way to hunt for alien life — not by searching for specific molecules, but by looking for hidden patterns in how those molecules are organized. Researchers discovered that living systems leave behind a kind of chemical “fingerprint” in the statistical distribution of amino acids and fatty acids, one that consistently differs from nonliving chemistry.

Gases collected from boiling mineral springs in Zambia contain the chemical signature of having come directly from the Earth’s mantle, a sign of a rupture in the tectonic plates and the possible beginning of a new continental boundary

Hubble has revealed a giant planet-forming disk unlike anything astronomers have seen before. Nicknamed “Dracula’s Chivito,” the enormous structure appears turbulent and oddly lopsided, with towering filaments visible on only one side. The disk contains enough material to potentially create multiple giant planets, making it a fascinating new laboratory for studying how planetary systems are born.

Astronomers using NASA’s James Webb Space Telescope have created the clearest map yet of the universe’s “cosmic web” — the enormous hidden structure that connects galaxies across space. By analyzing more than 164,000 galaxies through the massive COSMOS-Web survey, researchers were able to trace this vast network back to when the universe was just a billion years old.

A new study by planetary scientists at Harvard offers an explanation for one of Earth’s great climate puzzles: how the Sturtian glaciation, an ancient ice age when the planet was nearly entirely frozen, could have lasted 56 million years. A large igneous province in Canada helped them figure it out.

A new international scientific study by the Hellenic Space Center (HSC) has identified some of the most promising candidate cryovolcanic regions on Ganymede, Jupiter’s largest moon. These regions represent important targets for future observations by the European Space Agency’s Jupiter Icy Moons Explorer (JUICE).

Life on Earth depends on a critical dance of elements throughout the biosphere. One of these elements is Molybdenum, a transition metal that speeds up important biochemical reactions in cells. New research shows that despite its ancient scarcity, and despite the greater availability of other, similar metals, life "chose" Molybdenum earlier than thought.

By the 1960s, two major contributions were made to the field of SETI, both of which considered how more advanced civilizations could be found based on the types of structures they might build and the levels of energy they could harness.

Here’s a live Falcon Cam in New Jersey showing a breeding pair of peregrine falcons (Falco peregrinus).  The FB post about it says that one egg has already started to hatch.  The YouTube notes say this:

Conserve Wildlife Foundation of NJ is happy to partner with Union County to live stream the view of this peregrine falcon nest, which is located on the roof of the County Courthouse in Elizabeth, New Jersey. This view is from within the nestbox and captures more intimate moments between the breeding pair of falcons.

Tune in from time to time to see the babies.

Reader Jeremy “Jez” Grove went to Saturday’s Rally Against Antisemitism in London (he’s not Jewish, but a friend of the Jews), and sent me a nice report, along with photographs. Although all of us know that England is full of antisemitism these days, what with Jews getting stabbed and having their ambulances and schools set on fire or vandalized, I myself know little about the complex world of British politics, encompassing multiple parties. I was thus able to learn some things about the major parties and their attitude towards Jews.

I’ve indented Jez’s commentary, and the photos are his.

I’m on my way home from the rally against anti-Semitism, which was held outside the gates of Downing Street. Unsurprisingly, our prime minister didn’t manage to make the short walk to address the crowd and stand up against the rampant Jew hatred in the UK. (Instead, the Labour Party was represented by the Secretary of State for Work and Pensions, Pat McFadden, whose empty platitudes were barely audible over the shouts of “Where’s Keir?” and general booing.)

By contrast, Kemi Badenoch, the leader of the Conservative  Party, was met with rapturous applause and gave a barnstorming speech. I’d never vote Conservative, but Kemi has been outstanding on this issue and the fight for women’s rights.

Here’s part of Badenoch’s speech (you can see the full seven-minute version here):

I stand against antisemitism.

I stand against those people who want Jews to be afraid to go about their lives, and will never allow them to win.

The Liberal Democrats also sent their party leader, Ed Davey. He made the right sounds, but the response from the crowd was pretty lukewarm. That’s probably a reflection of his irrelevancy in British politics and his party’s invisibility on the issue. He’s best known for his ridiculous attention-grabbing stunts – the only surprise was that he didn’t arrive on the stage on a skateboard! (I’m barely joking, btw.)

The Reform UK party (generally seen as right of the Conservatives, but who just won big victories in Labour Party heartlands in our elections on Thursday) sent their deputy leader.

To no-one’s surprise, there was no representative from the (hugely anti-Semitic) Green Party, despite the boasts from their party leader, Zack Polanski, that he’s the only Jewish leader of a British political party.

It’s worth mentioning that there was a decent number of Iranian and Kurdish supporters of Israel present, who got the hearty applause that they deserved.

When I told Jez that it was ironic that the best speech of the day came from a Tory, he answered, “I guess the Tories aren’t much further to the right than your Dems. Maybe they’re even to the left of them – most Tories wouldn’t dare openly saying that they want to dismantle our (socialised) NHS. .”

I’ve attached a photo of the October Declaration flag. It was good to be amongst so many like-minded people standing up against anti-Semitism. Hopefully, the full event will be available to watch at some point soon.

Here’s the Campaign Against Antisemitism’s report on today’s rally. It contains a list of the speakers and some extracts from their speeches

Here are some of my (not very good) photos:

The airport-style security arches (I don’t believe that these have been required for pro-Palestine marches – because there has been no security threat posed to them): Note that the Jewish Community Security Trust (CST) felt it necessary to be present behind the London Metropolitan Police’s own barrier:

The  view looking from Trafalgar Square towards the stage outside Downing Street. One of the speakers claimed that the crowd was 20,000 strong. That seemed high to me, but given the security arrangements may have been a more accurate figure than is usual for protests of this type:

Support from the Iranians. The group were applauded as they left at the end of the event chanting “Long live Iran! Long live Israel”. They were also thanked for their presence from the stage as were those flying Kurdish flags:

I can’t remember who today’s speaker was who said he’d recently met the prime minister. And the PM audibly gasped when he was told that one synogogue alone was spending £20,000 a month on security. And the PM assured him that the “full weight of the law” would be used against those who had tried to burn down another synagogue. The speaker told him, “The 17-year-old suspect has just been released on bail and the only condition is that he doesn’t enter any synogogue”. The prime minister gasped again. But he didn’t have the guts to show up today. And nor did the deputy prime minister, or the chancellor, or any of the big names from the government’s cabinet. Instead, the Labour Party sent Pat McFadden (Secretary of State for the department of Work and Pensions). Only a political geek (guilty as charged) would know who he is. (My politically engaged wife recognised his name but couldn’t name his post.)

Shame on Labour – but even more shame on the anti-Semitic Green Party of England and Wales, who had two electoral candidates arrested for horrendous social media posts. [From the Guardian link below, the posts came from Saiqa Ali, a Lambeth Green candidate for Streatham St Leonard’s ward, and Sabine Mairey, who was standing in Lambeth’s Clapham Town.]

And according to the BBC, arrests were made of people trying to get knives into the rally.

When I asked Jez what those odious Green Party social media posts said, he responded:

The Guardian (!) reported (I can’t seem to do indented quotes, but what follows is all from The Guardian article archived here.

‘Ali’s Instagram account is set to private but screenshots indicated she had posted an image of an armed man wearing a headband of the banned Islamist group Hamas along with the slogan: “Resistance is freedom”.

Another screenshot indicated that Mairey had shared a post which included the text: “Ramming a synagogue isn’t antisemitism. It’s revenge.” ‘

Mark Sturtevant is back with some arthropod photos for us. His captions and IDs are indented, and you can enlarge his photos by clicking on them.

Today we have another set of pictures of arthropods from my area in eastern Michigan. Some of these were taken in the field and others were in a staged setting on the faithful dining room table.

During recent summers, I have been using cheap black lights on the front and back porch to attract more insects, and many new species have arrived as a result. One was this floofy moth that is clearly in the tiger moth (Arctiidae) family, but it was new to me. I believe this to be Spilosoma latipennis. If so, it should have hot pink legs, as shown in the link, but I did not know at the time to check for that:

Another arrival was this species of chafer beetle. This is an Oriental Beetle (Anomala orientalis). It is an invasive species from Asia that is becoming a minor pest here on turf grasses and other plants:

Moving on to spiders, here is a new species of spider called the Western Lynx Spider (Oxyopes scalaris). Lynx spiders can be easily recognized by their form, and especially by those prominent leg spines. They are sit-and-wait predators on plants. This male was missing one of its pedipalps, so I used editing tricks to replace it:

Next up is a lovely Orchard Orbweaver (Leucauge venusta), which had built its web across a seldom-used path in the woods. I had to stand on tippy-toes to get several partial focus stacks, and this final picture was grafted together by hand, piece by piece from those pictures. I really like their iridescent abdomens that look like antique porcelain, and those beautiful green legs. She was eating an unidentified Syrphid fly:

The next two pictures show a flashy jumping spider that I have only seen a few times. This is the Thin-spined Jumping Spider (Tutelina elegans), but to me it will always be called ‘the purple jumper’. The pictures were both taken in a staged setting, where the first is a focus stack, again needing much assembly, and the second was a “lucky shot” single frame. Lucky because she never once stood still, and she was always waving her front legs. I wonder if these spiders are trying to be ant mimics:

Back to insects. Folks here will have seen this one many times now, but it is still special. This is the Wasp Mantidfly (Climaciella brunnea). I won’t repeat again the improbable life cycle it has as a parasitoid on spider egg sacs. You can clearly see that it shows convergent evolution on praying mantids, and at the same time it is a wasp mimic. More specifically, it mimics various species and regional color variations of paper wasps (Polistes sp.). A detail about that which I think is really neat are its two-toned pigmented wings, which is an ersatz way to get its wings to resemble the wings of its models.

I show our local model wasp (P. fuscatus) in the next picture for comparison. Paper wasps have an extra crease that folds their wings length-wise, so the wings are dark and narrow. The mantidfly does not have the crease, so it fakes it with pigment:

Speaking of mantids, I finish with an amusing story about the next picture. This is a Chinese Praying Mantis (Tenodera sinensis), in hand, and the picture was taken with the Opteka 15mm wide angle macro lens. This fully manual lens is the most difficult lens that I own since to get the depth of focus that is much of the point for this kind of photography, one has to stop down the aperture to about f/32. As a result you are taking pictures with a pinhole camera, and focusing is done by guesstimation. Meanwhile, the working distances are extremely short so an insect subject is practically touching the lens. Anyway, she wasn’t having any of it, and quite honestly I was having a hard time keeping this big girl under control. So I made a short movie about the struggle, and attached an appropriate sound track to it. For those who have handled one of these insects, you know they will do what they want to do, and what they want to do is climb:

Sound up for the movie!

Scientists have pulled off a mind-bending quantum experiment that sounds almost impossible: they showed that tiny metal particles made of thousands of atoms can exist in multiple places at once. Using advanced laser techniques, researchers at the University of Vienna observed quantum interference in sodium nanoparticles far larger than the kinds of particles usually seen behaving this way. The finding pushes quantum mechanics into a new realm, suggesting that even surprisingly “large” objects still obey the bizarre rules of the quantum world.
