Genetically modified silkworms can produce fiber stronger than Kevlar

Chinese researchers have successfully genetically modified silkworms to produce webs that are 6 times stronger than Kevlar, which is used to make body armor. This is reported by the scientific publication Cosmos, citing a study published in Matter. Similar to silkworm silk, spider web is a natural polyamide fiber, while ... Read more

Scientists revived nematodes that rested in permafrost for about 46,000 years

German scientists managed to revive nematodes (parasitic roundworms) of an unknown extinct species that had been “sleeping” in the permafrost of Siberia for more than 46,000 years. This is reported by Vice, citing scientific publication of Max Planck Institute of Molecular Cell Biology and Genetics. The nematodes were found in ... Read more

Scientists have learned how tardigrades can survive dehydration

Tardigrades are micro-animals that can survive in the harshest conditions: extreme pressure, extreme temperature, radiation, dehydration, starvation, and even in the vacuum of outer space. The journal PLoS Biology published an article in which scientists at the University of Tokyo have identified a mechanism that explains how tardigrades can survive ... Read more

Scientists have changed the blood type of kidneys for transplantation: this increases the chances of patients with rare blood types to live

Cambridge University researchers successfully changed the blood type of three donor kidneys. The discovery could significantly improve the chances of patients with rare blood types waiting for a transplant, reports The Guardian. To change the blood type, scientists connected the kidney to a normothermic perfusion machine, which pumps oxygenated blood ... Read more

Scientists have revived the cells of the organs of dead pigs. This may help in organ transplantation

Medicine is far from overcoming death, but scientists are looking for ways to delay damage to dying and damaged organs. Yale University researchers were able to revive cells from pig organs that had been dead for over an hour. The animals’ hearts began to beat, and their bodies did not ... Read more
