Stem cells are capable of dividing for long periods of time, are unspecialized, but can develop into specialized cells. The earliest stem cells in the human body are those found in the human embryo. The stem cells inside an embryo will eventually give rise to every cell, tissue and organ ...
Stem cells are collected withan apheresis machine from the blood flowing through a catheter, which is inserted into a vein. Blood flows from a vein through the catheter into the apheresis machine, which separates the stem cells from the rest of the blood and then returns the blood to the pa...
With its $100 billion cumulative price tag, the ISS is one of the most expensive undertakings in human history. And for years, financial considerations have raised questions about its long-term future. The ISS will continue to receive funding from participating nations through the year 2030. And...
Rooting hormone is a tool you can use to encourage a cutting of a plant's stem and foliage to start producing root cells. Plants do this naturally, and while some plants can root themselves easily when you just stick them in a glass of water, others need a little chemical encouragement....
Autologous stem cells, derived from the patient’s own body, are often less expensive, typically ranging from $5,000 to $15,000. In contrast, allogeneic stem cells, sourced from a donor, are generally more expensive due to compatibility testing and sourcing requirements, usually starting around...
Orchids used to be fairly expensive and reserved for people with deep pocketbooks. Thanks to DNA and cloning technology, horticulturists now produce in the neighborhood of 100,000 affordable hybrid orchids [source:Natural Garden]. Orchid cloning, a form of tissue culture, is a sophisticated method...
It is often less expensive to get a quality grow tent than to try to make an effective grow space or grow box on your own. Here’s the same grow tent as above, but with cannabis plants inside: When thinking about where to grow indoors, you should also consider the temperature of your...
As facial recognition systems become less expensive, their use becomes more widespread. They are now compatible with cameras and computers that are already in use by banks and airports. Time Tracking A4Vision, a creator of facial recognition technology, is currently marketing a system that will kee...
To really stem the emission of greenhouse gases, we need to develop non-fossil fuel energy sources. Hydro-electric power, solar power, hydrogen engines and fuel cells could all create big cuts in greenhouse gases if they were to become more common. At the international level, the Kyoto treaty...
When Ralda Nehme, a cell biologist and neuroscientist, first started her lab at the Stanley Center for Psychiatric Research at the Broad Institute of MIT and Harvard in 2018, she realized a gap in the field. She was adept at growing stem cells in the lab
