Don't be shy to take on a little two-week side project. These five months will be the most precious three years of your academic journey.

A print of a whale next to an infographic of a nose and the following text 

Newfoundland's
Coast
Blackwood was born and raised in Wesleyville, a coastal community in northeastern Newfoundland. Young Blackwood and his father would load up their boat to fish and catch lobster in the Atlantic Ocean.
What is this smell?
This composition evokes the scentscape of Newfoundland's coast-a blast of briny, salty, iodine seawater, sea air-cured wooden structures, and a symbolic note of ambergris,* an animalic musk that originates in the belly of Sperm whales, as well as themes depicted in Blackwood's prints like ice floes, whales, and fishing towns. Rounding out the composition is fine seaweed absolute (Fucus vesiculosus, also known as "bladderwrack") and traces of dimethyl sulfide (DMS), the primary chemical that produces the scent of the sea released naturally by phytoplankton.
*The ambergris note is synthetic and does not contain any animol moteriots

Only ‘traces’ of dimethyl sulfide, I note. 🔭

Cubic Space Division (Cube Space Filling) | The Art Institute of Chicago Maurits Cornelis Escher, 1952

It's not a demo, but the best I've got is imagining living on a cube in Escher's Cubic Space Division, when the rods between the cubes are expanding. www.artic.edu/artworks/118... I think that intuitively gets across the idea of expansion with no centre, & you can derive Hubble's Law too...

I saw someone saying one of the astronauts was ‘the furthest anyone has been from their dog’ and am trying not to waste hours working which side of the Earth was where and whether any of the Apollo 13 crew had pets.

Candy was a leader of the Mars Zoo @zooniverse.bsky.social project, and sometime guest on #SkyAtNight. I hugely admired her leadership in all things, but her advocacy for the importance of getting a camera on Juno. She’ll be much missed. 🔭

Does anyone have recommendations for a restaurant in #Birmingham that could accommodate a group of 20-30, ideally in a private room. Nice but not fancy (and sadly probably not a balti!). Gastropubs? Budget is probably £75/head.

Artemis II Return
NASA's Orion spacecraft carrying Artemis II Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA, along with Mission Specialist Jeremy Hansen from the CSA (Canadian Space Agency), splashes down in the Pacific Ocean near San Diego, California, at 5:07 p.m. PDT, (8:07 p.m. EDT) on Friday, April 10, 2026. The Artemis II test flight launched on Wednesday, April 1, from NASA’s Kennedy Space Center in Florida to begin its 10-day journey around the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars. NASA’s Landing and Recovery team and the U.S. military are coordinating efforts to extract the Artemis II crew from the Orion spacecraft. Credit: NASA/Josh Valcarcel

Tides: A Key Driver in the Evolution of Terrestrial Vertebrates? Vertebrates have made a sea-to-land transition only once, which must have occurred prior to 395 Ma as documented through the discovery of a stem-tetrapod trackway in the Hold Cross mountains, Poland. The mechanisms behind such a transition are disputed, but biological perspectives suggest that it was a gradual progression and the symbiotic relationship of competition. Here, we hypothesise that the presence of strongly modulated tides may have been a significant driver in the transition. A large spring-neap range would have created a large intertidal zone, thus stranding sarcopterygians for several days. To survive, individuals with limbs better adapted to terrestrial navigation could flail back into the sea. These isolating tides may have paved the way for the emergence of terrestrial vertebrates. We evaluate the hypothesis by producing tidal simulations of the Siluro-Devonian period using paleogeographic plate reconstructions for two time slices prior to the trackway date. The analysis focuses on the resulting semi-diurnal tide and spring-neap range. The results show remarkable correlation between the location of both large semi-diurnal and spring-neap ranges (>4m) and notable fossil location and findings. For the 430 Ma time slice, these are concentrated around South China where the earliest evidence of lungs is found, at around 423 Ma. With the 400 Ma time slice, large ranges were located around Laurussia, where most stem-tetrapod fossils are believed to have originated. These results support the hypothesis, further suggesting the tides as a key driver in the development of not only limbs, but lungs also. In terms of tidal dissipation, the 430 Ma time slice is more energetic than the past 250 Ma. Indeed, the 400 Ma time slice is less energetic than the 430 Ma time slice, implying that the tides may go through a maxima/minima cycle in conjunction with the supercontinent cycle.
