Researchers develop technology to preserve vaccines in tropical temperatures

A team of British researchers have developed a simple, low-cost method to preserve vaccines in tropical climates, which they say could help to revolutionalize vaccination campaigns in developing countries, Reuters reports.

New improved enzyme could help facilitate spinal cord injuries

Researchers have developed an improved version of an enzyme that degrades the dense scar tissue that forms when the central nervous system is damaged. By digesting the tissue that blocks re-growth of damaged nerves, the improved enzyme - and new system for delivering it - could facilitate recovery from serious central nervous system injuries.

Drugs needed to preserve eggs for reproduction need to be given in stages

Cryoprotectants needed to preserve eggs for reproduction need to be given in stages, albeit rapid ones, say scientists who have developed a mathematical model that predicts optimal time for loading and unloading these drugs.

Researchers to develop a highly sensitive, portable method of detecting bioterror agents like anthrax

Their method uses "Cellular Analysis and Notification of Antigen Risks and Yields" (CANARY) cells, which are immune-system cells engineered to contain a fluorescent protein naturally found in jellyfish. CANARY cells have the immune system's ability to detect specific disease-causing agents, lighting up when they recognize a pathogen.

New storage method amplifies cells available for science

Like many other kinds of cells used in biomedical research, human embryonic stem cells are stored and transported in a cryopreserved state, frozen to -320 degrees Fahrenheit, the temperature of their liquid nitrogen storage bath. But when scientists thaw the cells for use in the lab, less than 1 percent awake from their frigid slumber and assume their undifferentiated state. This 'blank slate' form is characteristic of stem cells and essential for the basic science required before the promising cells are ready for the clinic.
