2021 RMS Digital Calendar

Why not download the RMS digital calendar? - each month you can have a new scientific image as your computer wallpaper or desktop.

Or if you'd prefer you can download:

All the images used were submitted to our annual calendar image competition, congratulations to those selected. You can download the 2021 images here:

January

Sea urchin (Paracentrotus lividus) collected in Aegean sea near Athens, Greece 
The sockets on the right are where the urchins long spines are attached. The element map (4076 x 3072 pixels, 0.42 µm pixel size) was acquired with an annular Bruker XFlash® FlatQUAD SDD at 6 kV for 51sec. without sample preparation. (Annular Bruker XFlash® FlatQUAD silicon drift detector)

Sprig of moss Cirriphyllum piliferum
This moss has thick cell walls that are birefringence. Therefore, it is well suited for shooting in polarized light. When using polarizing filters and a retardation plate, the petals start to sparkle in different colours (Biolam R-11 microscope, smartphone camera)

Airborne: Ilex 1
Pollutant particulates on the surface of a holly leaf. The image was collected using Energy Dispersive X-Ray Spectrometry to isolate elements of Aluminium, Magnesium, Calcium, Iron, Oxygen and Carbon. From a collaborative art and science project exploring air pollution on leaves with Rob Kesseler and Louise Hughes (Ultim Extreme EDS detector mounted onto a Tescan S 8000. EDS maps were layered over the BSE image using AZtec (version 4.1, Oxford Instruments))

A Fossilized Starfish?
Resembling a fossil of an ancient sea star called Ophiosamus kelheimensis from the Jurassic period, this is in fact an image of a thin crystalline film of an anti-inflammatory medication imaged in compensated polarised light microscopy (Olympus BX-51 with Sony A7 RII mounted on the trinocular port)

Pseudoscorpion Chernes cimicoides
Despite their appearance, these tiny creatures are perfectly harmless to humans, being minus the stinging tail of the true scorpions. They are common in the UK but under-reported on account of their small size (TESCAN MIRA 4 SEM, using the secondary electron detector in Depth Mode. Background masked and scale bar moved using Adobe Photoshop)

Entangled
Image of a blood platelet entangled in silk fibers obtained for a study on the interaction of biological samples and fiber materials. The image has been colorized using MountainsSEM® software. (JEOL JSM-6490LV SEM and MountainsSEM® Software) It was acquired by Simone Lauciello from the Italian Institute of Technology in collaboration with Giovanni Perotto from Smart Materials group.
