A research scientist at NASAs Kennedy Space Center in Florida cuts and stores strips of seed film - a new seed handling material containing red romaine lettuce seeds - inside the Space Station Processing Facility on Jan. 16, 2020. The seed film is being prepared for the VEG-03 J experiment that will fly to the International Space Station on Northrop Grummans 13th resupply services (NG-13) mission. This seed film experiment involves crew aboard the orbiting laboratory planting the seeds into plant pillows - a common method used to grow plants in space - themselves for the first time ever. The water-soluble, dissolving film addresses the challenge of handling seeds in a microgravity environment and also can be used to deliver fertilizers and other beneficial substances that help plants grow. NG-13 is scheduled to launch from the agencys Wallops Flight Facility in Virginia on Feb. 9, 2020, at 5:39 p.m. EST.

Photo documentary on bioprinting. Zurich University of Applied Sciences (ZHAW) is working with a bioprinter from regenHU to produce different human tissues. Bioprinting allows three dimensional tissue production in a fast and controlled manner by the precise positioning of primary cells, biomaterials and growth factors. Thereby, bioprinted tissues simulate the complex in vivo situation of our body. Tissues are produced in a layer by layer mode by alternating photopolymerized bioink and cells. Before using for substance testing the tissue are matured in a cell culture environment. In future, printed tissues could reduce animal experiments in drug development and foster regenerative medicine. The printed structure is visible in the well.

U.S. Marine Corps Cpl. Alexzander McGuire, a chemical, biological, radiological, and nuclear defense specialist with Command Element, 31st Marine Expeditionary Unit; swabs the contents of biological lab during a CBRN Response Element exercise on Okinawa, Japan, July 13, 2022. A CRE-EX tests CBRNs ability to respond to different operations, including investigating clandestine labs, containing chemical munitions, and countering weapons of mass destruction while performing reconnaissance, decontamination, and rapid insertion for casualties. The 31st MEU, the Marine Corps' only continuously forward-deployed MEU, provides a flexible and lethal force ready to perform a wide range of military operations as the premier crisis response force in the Indo-Pacific region.

Reportage in a laboratory which develops therapeutic vaccinations to treat small-cell lung cancer, using optimised cryptic peptide technology. These vaccinations are intended to treat cancer by stimulating the immune system so it can recognise and attack cancer cells, without harming normal cells. They target over-expressed antigens present in tumourous cells (universal tumour antigens). The lab grows T lymphocytes and dendritic cells. Dendritic cells are filled with optimised cryptic peptides (antigens), then put into contact with T cells so they become responsive to the antigen. The activated T lymphocytes are then able to target the cancer cells.

Dendritic cells are filled with optimised cryptic peptides (antigens), then put into contact with T cells so they become responsive to the antigen. The activated T lymphocytes are then able to target the cancer cells. The previously activated T lymphocytes are placed in the microplate which contains a membrane at the bottom of each well. Some wells contain the peptide and others dont (blank sample). When the peptide is present, the T cells react with the membrane (purple colouring), when the peptide is absent, there is no reaction.

This acrylamide gel is used to separate proteins. The colored spots are standard-size markers, which are prestained. This is usually used to make a western blot. The proteins are transferred to a membrane and then detected with an antibody to a specific protein. Photo by Diane A. Reid.
