The skeletons of long-lived bamboo coral (Family Keratoisididae) are promising archives for deep-water palaeoceanographic reconstructions as they can record environmental variation at sub-decadal resolution in locations where in-situ measurements lack temporal coverage. Yet, detailed three dimensional (3D) characterisations of bamboo coral skeletal architecture are not routinely available and non-destructive investigations into microscale variations in calcification are rare. Here, we provide high-resolution micro-focus computed tomography (µCT) data of skeletal density for two species of bamboo coral (Acanella arbuscula: 5 specimens, voxel size, 15 µm (central branch scans) and 50 µm (complete structure scan); Keratoisis sp.

September 2024
Background: Excessive opioid prescribing following surgery contributes to the growing opioid crisis. Prescribing practices are modifiable, yet data to guide appropriate prescription of opioids at surgical discharge remain sparse. This study aimed to evaluate factors associated with opioid consumption following discharge from surgery.

Plant diversity effects on community productivity often increase over time. Whether the strengthening of diversity effects is caused by temporal shifts in species-level overyielding (i.e.

This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.
Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures.

Article Synopsis
- Climate change is making droughts (periods without rain) happen more often and for longer periods of time, which is bad for ecosystems.
- Scientists did a big experiment in many places around the world to see how one year of drought affects grasslands and shrublands.
- They found that extreme drought can reduce plant growth much more than expected, especially in dry areas with fewer types of plants, showing that these places are more at risk.
