This follow-up to the influential 28 Days Later continues to take the zombie movie franchise in a surprising and thought-provoking direction

Material science plays an absolutely critical role in space exploration. So when a new type of self-healing composite is announced, it’s worth a look–especially when the press release specifically calls out its ability to repair microtears associated with micrometeoroid impacts on satellites. It sounds like just such a composite material was recently invented at North Carolina State University - and it’s even already been spun out into a start-up company.

A popular idea suggests a link between big brains and a rich social life, but octopuses don't fit the pattern, which suggests something else is going on

A new building material developed by engineers at Worcester Polytechnic Institute could change how the world builds. Made using an enzyme that turns carbon dioxide into solid minerals, the material cures in hours and locks away carbon instead of releasing it. It’s strong, repairable, recyclable, and far cleaner than concrete. If adopted widely, it could slash emissions across the construction industry.

Solar Orbiter has captured the clearest evidence yet that a solar flare grows through a cascading “magnetic avalanche.” Small, weak magnetic disturbances rapidly multiplied, triggering stronger and stronger explosions that accelerated particles to extreme speeds. The process produced streams of glowing plasma blobs that rained through the Sun’s atmosphere long after the flare itself.

Scientists have discovered that the human brain understands spoken language in a way that closely resembles how advanced AI language models work. By tracking brain activity as people listened to a long podcast, researchers found that meaning unfolds step by step—much like the layered processing inside systems such as GPT-style models.

How can scientists estimate the pH level of Enceladus’ subsurface ocean without landing on its surface? This is what a recently submitted study hopes to address as a team of scientists from Japan investigated new methods for sampling the plumes of Enceladus and provide more accurate measurements of its pH levels. This study has the potential to help scientists better understand the subsurface ocean conditions on Enceladus and whether it’s suitable for life as we know it.

Humpback whales off the west coast of Canada have learned a cooperative hunting technique from whales migrating into the area, and this cultural knowledge may help the population cope as food becomes scarce

Newly developing stars shrouded in thick dust get their first baby pictures in these images from NASA’s Hubble Space Telescope. Hubble took these infant star snapshots in an effort to learn how massive stars form. Protostars are shrouded in thick dust that blocks light, but Hubble can detect the near-infrared emission that shines through holes carved in the gas by the young stars themselves.

The Ring Nebula is a well-studied planetary nebula about 2,570 light-years away. Nnew observations of the nebula with a new instrument have revealed a previously unseen component. The William Herschel Telescope used its WEAVE instrument to detect a massive 'iron bar' inside the nebula's inner layer.

Two or more satellites could communicate and manoeuvre around one another using magnetic fields, although getting the technique to work at scale in space might be tricky

The US’s federally funded space program has been struggling of late. With the recent cancellation of the Mars Sample Return mission, and mass layoffs / resignations taking place at NASA, the general sense of a lack of morale at the agency is palpable, even from a distance. Jared Isaacman, the billionaire software entrepreneur and rocket enthusiast who was recently confirmed as NASA administrator during his second confirmation hearing, hopes to change that, and one of his priorities is pushing the Artemis missions for a permanent human presence on the Moon. However, at least one big technical hurdle remains before being able to do so - how to power a base during the two week long lunar night. A recent press release describes how NASA, and another branch of the federal government (the Department of Energy - DoE) hope to solve that problem - with a lunar-ready nuclear fission reactor

Well, the cease-fire agreements in Gaza are proceeding, as Trump has appointed some committees (all approved by the UN) to run the territory. But again we have a dog’s breakfast, as there are multiple committees with two big problems: there are at least five committees with somewhat overlapping functions and members, and, second, there is no roadmap for the major task of getting rid of Hamas.

Here’s the composition as given by the NYT (bolding below is mine):

Mr. Trump’s “Board of Peace,” which he named himself the chairman of, is backed by a legal United Nations mandate and had previously been expected to be composed of world leaders who would supervise the Trump administration’s plan for an “International Stabilization Force” to occupy, demilitarize and govern Gaza during a yearslong reconstruction effort.

But the list of officials on the executive board announced on Monday included three members of the Trump administration — Secretary of State Marco Rubio, Steve Witkoff and Robert Gabriel — as well as Jared Kushner, Mr. Trump’s son-in-law; Ajay Banga, the head of the World Bank; the billionaire Trump ally Marc Rowan; and former Prime Minister Tony Blair of Britain. Of the seven, only Mr. Blair is not American, and he was previously the Middle East envoy for the Quartet, a diplomatic group made up of the United States, Russia, the United Nations and the European Union, and considered a candidate to lead a transitional government in Gaza.

A second executive board, similarly named the “Gaza executive board,” includes a wider roster of foreign officials from Europe and the Middle East, and is implied to be in a supporting role. Some American officials sit on both executive boards, as well as Mr. Blair.

Maj. Gen. Jasper Jeffers, the commander of U.S. Special Operations Command Central, which operates in the Middle East, was also tapped to lead the “International Stabilization Force,” the peacekeeping force authorized by the United Nations to be deployed to Gaza as part of the peace plan. General Jeffers previously helped oversee a brokered cease-fire between Israel and Lebanon last year.

Note that what seems to be the most important committee is almost all American, and the peacekeeping force, which presumably will be tasked with disarming Hamas, is also headed by an American general.  So who is going to disarm Hamas? Israel can’t, as that would violate the ceasefire agreement, and the U.S. certainly won’t send troops to Gaza. So how will Hamas disarm and disband: the first item on Trump’s agenda?

Trump apparently will solve it by threats:

It is not clear how the international force would ensure that Gaza is demilitarized. Hamas, which specializes in insurgent tactics and has not disbanded its battalions of armed fighters, has long regarded giving up all its weapons as tantamount to surrender, with armed struggle against Israel a crucial part of its ideology. On Thursday, Mr. Trump threatened Hamas with a renewed conflict if they did not disarm, writing on social media: “they can do this the easy way, or the hard way.”

The Times of Israel, as usual, has more information about the committees, and notes that the Board of Peace isn’t really the most important board, with the Gaza Executive Board really tasked with doing the heavy lifting. Bold headings are mine. And the ToI article implies that the NYT missed two committees:

The Board of Peace:

The Board of Peace is the umbrella body that was mandated by the UN Security Council to oversee the postwar management of Gaza until the end of 2027.

The Board of Peace is chaired by Trump, and will largely be made up of heads of state from around the world.

Formal invitations to become members of the Board of Peace were sent out on Friday, and by Saturday the leaders of Turkey, Egypt, Canada and Argentina confirmed having received the offer — an indication that they will likely accept

While this is the most prominent of all the panels established, the Board of Peace will play a generally symbolic role and be more relevant during the fundraising stage, a senior Arab diplomat told The Times of Israel.

The Gaza Executive Board:

The Gaza Executive Board is the operational arm of the Board of Peace and the body that will actually oversee the postwar management of Gaza.

Sitting on the Executive Board are Turkish Foreign Minister Hakan Fidan, senior Qatari diplomat Ali Thawadi, Egyptian intelligence chief Hassan Rashad, UAE Minister of International Cooperation Reem Al-Hashimy, former UK prime minister Tony Blair, US special envoy Steve Witkoff, top Trump aide Jared Kushner, Apollo Global Management CEO Marc Rowan, Israeli-Cypriot businessman Yakir Gabay, former UN humanitarian coordinator Sigrid Kaag, and former UN envoy to the Mideast Nickolay Mladenov.

Israel has expressed opposition to the makeup of the Executive Board, apparently taking issue with the inclusion of representatives from Turkey and Qatar, who were heavily critical of its prosecution of the war in Gaza.

However, the inclusion of both countries demonstrates their perceived utility to Trump, who has touted his personal relationships with the leaders of Turkey and Qatar as well as their success in pressuring Hamas to accept a ceasefire deal in October.

The Founding Executive Board:

In addition to inexplicably sharing nearly the same name as the Gaza Executive Board, the Founding Executive Board also consists of many of the same members.

Joining Witkoff, Kushner, Blair and Rowan on this additional board are US Secretary of State Marco Rubio, World Bank president Ajay Banga and Trump’s former deputy national security adviser Robert Gabriel.

The White House said that each member of the Founding Executive Board “will oversee a defined portfolio critical to Gaza’s stabilization and long-term success, including, but not limited to, governance capacity-building, regional relations, reconstruction, investment attraction, large-scale funding, and capital mobilization.”

The National Committee for the Administration of Gaza:

. . . .The National Committee for the Administration of Gaza is the committee of Palestinian technocrats that will be tasked with running daily affairs on the ground and providing services for Gazans in place of Hamas.

While Egypt, in announcing the new panel, claimed it consists of 15 members, the actual figure is 12, and they are headed by former Palestinian Authority deputy planning minister Ali Shaath.

. . . . Each of the other panel members was given a portfolio covering the fields in which they are experts.

Abdul Karim Ashour, who heads an agricultural non-profit, will serve as agriculture commissioner.

Aed Yaghi, who currently heads the Palestinian Medical Relief Society, will serve as health commissioner.

Osama Sa’adawi, who previously headed the Palestinian Housing Council nonprofit, will serve as housing commissioner.

Adnan Abu Warda, a former PA Supreme Constitutional Court judge, will serve as justice commissioner.

Maj. Gen. Sami Nassman, who has served in the PA’s General Intelligence Service and is seen as a strong opponent of Hamas, will serve as internal security and police commissioner

And so on, including commissioners for water and municipal affairs, social affairs, communications, economy, and trade. You can see that their duties will overlap. Who resolves conflicts? A member of the Palestinian Authority, which of course is anti-Israel, and is an organization hated by Hamas.  Finally, there is the crucial

International Stabilization Force:

The International Stabilization Force is tasked with providing security for the Strip, while gradually phasing out the IDF, which currently remains in control of 53% of the enclave.

While the US has said the ISF will support efforts to disarm Hamas, officials familiar with the matter said the multinational force won’t be expected to engage in kinetic activity to seize weapons from the terror group, which has pledged not to give them up.

Instead, they will support the disarmament process once an agreement is reached, with mediators optimistic that Hamas will agree to a gradual process that starts with the return of heavy weapons, Arab and US officials have said.

. . .The US had struggled to convince countries to contribute troops to the ISF board amid heavy skepticism that Hamas will disarm and that the IDF will withdraw further from Gaza. One of the two countries Washington had publicly touted, Azerbaijan, announced earlier this month that it would not be participating.

US officials briefing reporters last week insisted that they now have enough countries offering troops and that an announcement can be expected in about two weeks.

This is a mess.  There are five committees whose jobs are overlapping, a heavy U.S. presence on the supervising Board of Peace, and what I see as the most important committee at the outset—the group tasked with demilitarizing Gaza by erasing Hamas—has no specified troops.

It’s not surprising that no country wants to take on Hamas, since they know the international opprobrium attached to that task.  Since Hamas refuses to disarm, this guarantees that there will be extensive fighting in Gaza for a long time to come.  Getting rid of Hamas is Job #1, and until that is done, none of the other committees can do their jobs.

Now the UN could run the whole show instead of the U.S., but that might be even worse given the UN’s hatred of Israel. I doubt that the UN has the stomach to disarm Hamas. They have UN troops that could try, but the UN troops in Lebanon, tasked with disarming Hezbollah, are completely ineffectual. UN troops would be useless against the determined fighters of Hamas.

My conclusion: this messy plan won’t work, and therefore the destruction in Gaza will continue for some time to come.  And don’t forget that Hamas and the Gazans hate the Palestinian Authority, so there can be no solution that allows the PA to run the Gaza Strip. I feel for the Gazan civilians that must endure this mishigass for years to come. If readers have an alternative solution, do suggest it below.

To describe the odious, terroristic nature of Hamas, which all of you should know about by now (even though many young Americans are on their side), I proffer Rawan Osman, a Syrian-born but pro-Israeli activist who was brought up as an Israeli-hating Muslim:

It is impossible to get rid of anxiety because it exists to help us, says cognitive psychotherapist Owen O'Kane. Instead, he suggests three ways to reframe your relationship with anxiety in order to take back control

We recently discussed the different types of worlds that the Habitable Worlds Observatory (HWO) is expected to find that might have noticeable biosignatures. However, no matter how good the instrumentation on board the observatory is, the data it collects will be useless if scientists don’t know how to interpret it. A paper explaining what data they need to collect before analyzing HWO data was authored by Niki Parenteau, a research biologist at NASA, and her co-authors, which is now available in pre-print on arXiv.

Regular Mark Sturtevant (as opposed to Irregular Mark Sturtevant) has sent in some lovely insect photos to fill the nearly-empty reserve of pictures. Please send any good wildlife photos you have. Thanks!

Mark’s captions are indented, and you can enlarge his photos by clicking on them. Be sure to check out the female Tussock Moth caterpillar with vestigial wings (it’s the eighth photo).

Here is another dispatch of local insects and spiders, all photographed either in area parks near where I live in eastern Michigan, or as staged shots at home. Let’s start with a couple of dragonflies. First up is a Green Darner (Anax junius), which ranks pretty large among the dragonflies found here. As is almost always the case, this individual is a female, since they perch frequently and are much easier to approach than males, which I only rarely manage to photograph. Do you see the tiny yellow critter on the dragonfly? That is a Globular Springtail, and it must have walked or jumped onto the dragonfly from nearby foliage. There may be a few more of them in the picture as well, though I’m not certain. Springtails are tiny soil arthropods, and they are extremely abundant. When seen up close, Globular Springtails are arguably adorable, as you can see in the linked image. I’ve searched for them for some time but have only rarely encountered them, despite claims that they are exceedingly common. Perhaps our local species spends more time up on foliage rather than in the soil, meaning I’ve been looking in the wrong places!:

The next dragonfly is a male Skillet Clubtail (Gomphurus ventricosus), named for the large, pan-like club on the end of its abdomen. I have to drive a few hours south to a particular park to see them, and of course this one is perching on poison ivy which covers much of the area there. That park hosts 8 or 9 species of clubtails according to a dragonfly documentation site called Odonata Central. I’ve photographed most of those species with only two left to find:

A field near my workplace has a ridiculously high population of Chinese Praying Mantids (Tenodera sinensis). I suspect this is the lingering result of someone having released a large number of egg cases several years ago, combined with a robust population of grasshopper prey. Shown here is a young June nymph. I can return later in the summer to find several large adults in no time at all:

Next up are some lepidopterans. First is a Hackberry Emperor butterfly (Asterocampa celtis). They are often common along forest margins where their host Hackberry trees [Celtis occidentalis] are concentrated. Their caterpillars, however, seem to be quite secretive, as I’ve seen only a few of them:

Next is an inchworm caterpillar, though I don’t have an identification for it. Do you see the tiny mites?:

The insect shown next is a moth, although it makes a very convincing wasp mimic. This is the Eupatorium Borer Moth (Carmenta bassiformis). The larvae feed on the roots of Ironweed and Joe Pye Weed, both of which are highly valued native wildflowers because they are very much favored by butterflies:

The flamboyant caterpillar in the next image is a White-marked Tussock Caterpillar (Orgyia leucostigma). I’ve tried several times to get an acceptable focus-stacked image of one of these. What makes them difficult is the combination of all those oddly angled sticky-out bits, which challenge the shallow depth of field inherent in this kind of photography, along with the fact that these caterpillars absolutely will Not Hold Still. As a result, the stacking is done on the fly, followed later by long hours of manual reassembly of the jumbled focus stack. This image is by far my most successful attempt:

I kept this caterpillar in hopes that the moth emerging from the cocoon would be a female. Why? Well—check out what came out! It was a female! Females have barely visible vestigial wings, and I had never seen one before. She will sit here, unmoving, until a male finds her. This strategy saves a great deal of energy that can instead be used for laying eggs. The winged males are unremarkable, and while I’ve probably seen them, I don’t think I’ve ever photographed one:

Finally, here are three images of jumping spiders I’ve been wanting to share together for quite some time. The Dimorphic Jumping Spider (Maevia inclemens) is a species I regularly see around the outside of our house. The name refers to the males having two distinct color morphs. The images below are manual focus stacks, photographed in staged settings on the ‘ol dining room table. First is a female with long-legged fly prey, which conveniently provides a sense of scale since the fly is about the size of a mosquito:

Next are the two male color morphs. The first somewhat resembles the females, while the other is very different and comes with distinctive hair decorations. This is an older image, but I’m bringing it back so all three forms can finally be shown together. It’s surprising that they are all the same species!

I recently learned that the two male forms use different courtship displays for females, yet are considered equally successful in the mating game. I’m sure Jerry can steer things in the right direction if I am in error here, but having different male forms with different mating strategies does not seem unusual in the animal kingdom. Examples I’m familiar with include lizards, crustaceans, and fish, although in those cases the different males include those that are aggressive and territorial, and others that win by being sneaky. But here, I don’t see how either male is territorial, and apparently both have courtship displays for females.

One of my goals for next season will be to try to document their different courtship behaviors. That seems do-able, since I can expect to find several of them again next summer.
