Scientists have discovered that proteins from tardigrades can slow down metabolism in human cells, potentially leading to technologies that slow the ageing process. Tardigrades, known for their ability to survive extreme conditions, use proteins to form gels inside their cells, which when introduced into human cells, slow down metabolism and make the cells more resistant to stresses. This finding could pave the way for the development of new technologies focused on inducing suspended animation in cells or organisms to slow ageing, and also suggests that tardigrade proteins could be used to enhance the storage potential of therapies like stem cells.

Scientists from the University of Wyoming have discovered that expressing key tardigrade proteins in human cells can slow metabolism, providing insights into how these resilient organisms survive extreme conditions. The study focused on a protein called CAHS D, which transforms into a gel-like state under stress, protecting molecules and preventing drying. Introducing these proteins into human cells can induce biostasis, making the cells more resistant to stresses and potentially offering avenues for slowing aging and enhancing cell storage. Further research is underway to harness these abilities for applications such as organ transplants and stabilizing blood products.

Scientists studying tardigrades have discovered that the proteins responsible for the creatures' ability to enter a state of suspended animation, called biostasis, could potentially be used to slow down human aging. By introducing tardigrade proteins to human cells in a lab, researchers found that the cells slowed down and entered a hibernation-like state, similar to the tardigrades. This discovery could lead to the development of technologies aimed at inducing biostasis in cells and organisms to slow aging and enhance storage and stability. Additionally, it could expand access to lifesaving drugs by allowing for the shipment of temperature-sensitive medicines without refrigeration.

Researchers at Tufts University and Harvard University's Wyss Institute have developed microscopic biological robots called Anthrobots, made from human tracheal cells, that can move across surfaces and promote the growth of neurons in damaged areas. These self-assembling multicellular robots, ranging in size from a hair-width to the point of a sharpened pencil, have shown remarkable healing effects in lab conditions. Unlike previous Xenobot research, Anthrobots can be created from adult human cells without genetic modification, making them a potential patient-specific therapeutic tool in regenerative medicine. The researchers envision using Anthrobots for treating various diseases and injuries.

Scientists have developed tiny living robots, called anthrobots, using human cells that can move and potentially aid in wound healing and tissue regeneration. The researchers used tracheal cells with cilia, which were manipulated to face outward and act as oars for movement. The anthrobots exhibited different shapes, sizes, and movement patterns. In experiments, they showed the ability to encourage growth in damaged human neurons. The study provides a foundation for future applications of bio-bots in various forms, with potential uses in medical research and treatments. The anthrobots are not genetically modified and have a limited lifespan, biodegrading after a few weeks.
