In April, we got a short teaser for the third season of Silo, the critically acclaimed Apple TV series based on the trilogy by novelist Hugh Howey, which hinted at a mysterious origin story dating back centuries. Apple TV just released the full trailer, and it looks like our heroine is again facing conflict and danger because she just keeps asking so many inconvenient questions.

As previously reported, Silo is set in a self-sustaining underground city inhabited by a community whose recorded history dates back only 140 years. The outside is a toxic hellscape that is only visible on big screens in the silo’s topmost level. The second season expanded Silo‘s world to incorporate the survivors in the second Silo 17; everyone else died in a revolt to escape to the surface. We discovered that there are 50 silos in all. Meanwhile, another revolution was brewing in Juliette’s (Rebecca Ferguson) original Silo 18 against Holland (Tim Robbins). And even more secrets were revealed.

In the season finale, Juliette returned to her silo and warned the residents not to leave, but she and Holland ended up locked in the incinerator just as it was being fired up. The final scene was a flashback, showing a woman questioning a congressman in Washington, DC, about possible retaliation after the US dropped a dirty bomb on Iran. And that brings us to S3. Per the official premise:

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. May's list includes the discovery of a possible prehistoric mining site in the Pyrenees; a new species of tiny blue octopus; why cats seem to prefer silver vine to catnip; and why political polarization might behave like a phase transition, among other noteworthy stories.

High in the eastern Pyrenees is a prehistoric cave, excavated between 2021 and 2023. Based on analysis of artifacts uncovered at the site, a team of Spanish archaeologists believes this may have served as an ancient copper smelting spot, with far more frequent occupation by humans than previously thought. The researchers described these preliminary findings in a paper published in the journal Frontiers in Environmental Archaeology.

Scientists have long known that migrating birds and homing pigeons navigate in part by sensing the Earth's magnetic fields, especially at night or in overcast conditions when visual landmarks or sunshine are in short supply. But exactly where this magneto-sensing occurs in the body—and the mechanism that enables it—remains a matter of intense debate. A new paper published in the journal Science suggests that homing pigeons have iron-rich immune cells in their livers that help them detect magnetic fields and transmit that information to the brain.

There are three primary hypotheses for how birds might sense Earth's geomagnetic field. One is a compass-like mechanism, whereby the Earth exerts a pull on magnetic particles in a bird's upper beak that relays directional information via a large nerve in the cranium. A second is that it happens biologically via cellular ion channels sensitive to voltage, enabling birds to sense changes in the magnetic field. And a third suggests that physical effects on retinal pigments enable birds to detect photons and send signals to the brain, although this mechanism is really only viable in the light.

None fully explain how animals can sense magnetic fields. However, “We had some clues that the liver and spleen have magnetic properties, because they break down red blood cells and so store much iron in the body,” said co-author Clivia Lisowski of the University of Bonn and the University Hospital Bonn. This refers to a 2015 paper suggesting that red pulp macrophages in the spleens of mice and humans are intrinsically superparamagnetic and hence more sensitive to magnetic fields. But it wasn't clear if those properties were involved in any kind of magnetoreception.

Some viewers were disappointed that the second season of House of the Dragon ended not with a bang, but a whimper. But the big battle sequence that season 2 set up will open season 3 with a bang, judging by the latest trailer, which has all the dragons, fire, and blood Westeros is known for.

(Spoilers for first two seasons below.)

As previously reported, the series is set nearly 200 years before the events of Game of Thrones, when dragons were still a fixture of Westeros, and chronicles the beginning of the end of House Targaryen’s reign. The primary source material is Fire and Blood, a fictional history of the Targaryen kings written by George R.R. Martin. As book readers know, those events culminated in a civil war and the extinction of the dragons—at least until Daenerys Targaryen came along.
