If you’re using plain yogurt or fresh lemon juice for a salad or fruit, instead of adding saffron extract, just use a few drops of oil such as olive oil, tahini, olive vinegar or lemon juice in a pinch. You can also use a little bit of olive oil and vinegar, or even a little bit of vinegar, as a substitute for saffron.

What happens when 2,000 year old bones are turned into a 3D printer? Scientists from the University of Sheffield have revealed some intriguing insights into the potential applications of bone printing. They say it could lead to the creation of artificial joints that could help regenerate damaged tissues when worn down.
The bone is 3D printed and then embedded with polyurethane filler. The filler has the property of being water tight and the bone itself is designed to contract and expand when the pressure is high. The body’s cells are then able to process both the nutrients and waste products into molecules that can be used for medicine, food, cosmetics, and more.
The team discovered that the material in the bone can be printed with tiny holes in it to allow a cell to grow into the material. These holes are sealed by a plastic microbubble that surrounds the material in a ‘wet bed’ fashion.
The team found that by allowing the stem cells of the animal to grow into the material, the material could be used for prosthetic limbs. This is due to the fact that the area of the animal’s body where the bone is found is relatively small compared to a human brain, so it is much easier for the stem cells in the bone to ‘grow’ in the structure. Using the same technique, they also show they could print a human kidney into the structure.
Professor Chris Chibnall, who led the research, said: “We are using this printing technique to print structures into a living body and this means that it is possible to create a unique object from 3D printing. We
