@leicesterucu.bsky.social Today we had s lovely showcase from modern languages and why it matters in a multi-lingual city as Leicester. And our students stand with us every day, thank you!

@leicesterucu.bsky.social Our students deserve a big thanks for supporting us at the picket line every day, now in week 2. It means a lot to have the students backing for fighting the looming job cuts at University of Leicester in 6 schools

Coral reefs with high ecological integrity are able to quickly recover from extreme climate impacts. In our new study in Coral Reefs, we found high integrity Fiji reefs were able to rebound rapidly following a category 5 cyclone.

How the Southern Ocean controlled climate and atmospheric carbon dioxide during the lukewarm interglacials

Earth's climate has fluctuated between cold and warm periods for millions of years. During the so-called "lukewarm interglacials"—warm phases between 800,000 and 430,000 years ago—atmospheric CO2 conc...

Let's start with the base fact that Neutron Tomography is a really cool thing. Fossils are also very cool (even if they're corals). Combining the two gives a very interesting way to look at diagenesis (or screen for it, if you're boring). 🧪⚒️

Comparison of neutron computed tomography (NCT) scans (a–c) with traditional X-Ray CT image (d) of the modern unaltered Porites sample from One Tree Reef. 3-D voxels measure 0.0395 mm3, sample thickness ca. 1 cm (a) 3-D NCT scan showing full neutron count range 0–65,535, (b) 3-D filter applied showing aragonite data range exclusive of porosity (ca. 12,000–65,535 NC). Histogram shows two distinct peaks representing porosity and aragonite ranges. (c) Cross sections V-V′ and XZ-XZ’ are 2-D slices of the 3-D NCT slab data (39.5 μm resolution) of V (vertical) and XZ (x axis and depth) profiles, respectively. Their positions are indicated by white lines in (a). (d) X-Ray CT image of the same slab used for photos (a, b) showing density variations and blurry low resolution coral morphology.
