Project Apollo Archive

The Project Apollo Archive brings together all the photos from the Apollo lunar expeditions, which are now in the public domain.

One can thus find some educational materials or simply rare images of Pluto !

The GBIF — Global Biodiversity Information Facility — which is an international network and research infrastructure funded by world governments with the aim of providing everyone, everywhere free access to data on all life forms on Earth.

Coordinated through its Copenhagen Secretariat, GBIF’s network of participating countries and organizations, operating through Participant Nodes, provides data-holding institutions around the world with common standards and open-source tools to share information when and where the species were observed. This knowledge comes from multiple sources : from museum specimens collected in the 18th and 19th centuries to georeferenced photographs recently shared by an amateur naturalist using his smartphone.

Mushroom Observer

The purpose of Mushroom Observer is to record observations about mushrooms, to help people identify mushrooms they don’t know about, and to expand the community of people who engage in the scientific study of mushrooms (mycology).

Some wonder what a fungus is. The site has taken a very broad approach to this. Although the main focus is on fleshy fungi, other fungi such as lichens, rusts and molds, as well as fungal-like organisms, such as slime molds, are all welcome.

Ultimately, we hope the site will become a valuable resource for both amateur and professional mycologists. We like the idea that the site is seen as a living guide to mushroom identification or as a collaborative mycological field diary.

Proteopedia is an online encyclopedia, presenting 3D images, operating on the principle of wikis. It deals with proteins and other molecules related to biology.

The encyclopedia site offers a page for each entry in the Protein Data Bank (more than 77,000 pages), but also pages concerning the description of the structures of the constituents of proteins in the broad sense and related articles relating, for example, to acetylcholinesterases , hemoglobin or Photosystem II. These 3D descriptions use images elaborated via Jmol, a Java applet. The images highlight functional locations (called sites) and ligands (molecules with their bonds).

The aim of a World Register of Marine Species (WoRMS) is to provide an authoritative and comprehensive list of names of marine organisms, including information on synonymy. While the highest priority goes to valid names, other names in use are included so that this register can serve as a guide to interpret taxonomic literature.

The content of WoRMS is controlled by taxonomic and thematic experts, not by database managers. WoRMS has an editorial management system where each taxonomic group is represented by an expert who has the authority over the content, and is responsible for controlling the quality of the information. Each of these main taxonomic editors can invite several specialists of smaller groups within their area of responsibility to join them.

And there are beautiful pictures ;)
