Snow alga Sanguina aurantia as revealed through de novo genome assembly and annotation.

To thrive on melting alpine and polar snow, some Chlorophytes produce an abundance of astaxanthin, causing red blooms, often dominated by genus Sanguina. The red cells have not been cultured, but we recently grew a green biciliate conspecific with Sanguina aurantia from a sample of watermelon snow. This culture provided source material for Oxford Nanopore Technology and Illumina sequencing.

Rosetta gen. nov. (Chlorophyta): Resolving the identity of red snow algal rosettes.

Thick-walled rosette-like snow algae were long thought to be a life stage of various other species of snow algae. Rosette-like cells have not been cultured, but by manually isolating cells from 38 field samples in southern British Columbia, we assigned a variety of rosette morphologies to DNA sequence. Phylogenetic analysis of Rubisco large-subunit (rbcL) gene, ribosomal internal transcribed spacer 2 (ITS2) rRNA region, and 18S rRNA gene revealed that the rosette-like cells form a new clade within the phylogroup Chloromonadinia.

Satellite mapping of red snow on North American glaciers.

Red snow caused by blooms of microalgae darkens the surface of summer snowfields, increasing snowmelt. To assess the contribution of red snow to supraglacial snowmelt in northwestern North America, we systematically mapped the 2019-2022 distribution of blooms by applying supervised classification to 6158 satellite images. Blooms occurred on 5% of the total glaciated area, heavily affecting many glaciers in years of prolonged snow cover duration.

Psychological support during a pandemic: an intervention for hospital teams.

Background: The COVID-19 pandemic placed unprecedented stress on healthcare professionals and resulted in teams being scattered by shielding, working from home and redeployment. The Recovery, Readjustment and Reintegration programme (R3P) was implemented and evaluated in an acute NHS hospital Trust with the aim of supporting those staff involved.

Aims: To explore the impact of offering themed reflective sessions to staff in an acute hospital and to disseminate this learning for application in other settings and future pandemics.

Staff support during COVID-19 within an Acute Hospital Trust.

Background: The COVID-19 pandemic has put immense pressure on the National Health Service (NHS) and all healthcare professionals, not only physically but also mentally and the need to fully develop and implement a strategy to protect the mental health of healthcare professionals has never been more urgent. Research has demonstrated that staff can be supported by strengthening teams and offering frequent well-being support.

Aims: To assess the feedback from delivery of a strategy to provide psychological well-being support to NHS staff during the COVID-19 pandemic and whether this 'Support for Teams' initiative made a positive impact on staff and in what way.
