Crazy: Scientists decide to use DNA to "resurrect" mammoths within 6 years
Recently, CNN reported that American experts plan to "resurrection" the mammoth and plan to breed the first batch of "elephant cubs" within 4-6 years. This project, which is close to science fiction, is led by Professor George Church of Harvard Medical School. Currently, the project has received an investment of US$15 million.

breakthrough! 3D nano-ink breaks the bottleneck
A new 3D printable polymer nanocomposite ink has incredible properties and finds widespread use in aerospace, medicine and electronics. Mechanical engineering researchers at Michigan Technological University in the United States have invented a method to use carbon nanotubes (CNTs) to make 3D printing nanocomposite polymer ink, which is expected to replace traditional epoxy resin.

"Science" big news! The secret of longevity that can live for 200 years was found deep in the ocean!
For natural life, aging and death are inevitable. A common hallmark of aging is that cells slowly lose their ability to produce new, healthy cells to repair damage. However, as both vertebrates, some Pacific rockfish can live for more than 200 years, while others can only live for about 10 years. The life span of the two differs by 20 times! This also makes the former one of the longest-lived vertebrates. This difference in lifespan has attracted keen interest among scientists.

Freezing juvenile testicular tissue to preserve male fertility
Nowadays, the incidence rate of cancer is getting higher and higher, and it is getting younger and younger. Many people are not yet married and have children, but unfortunately they are suffering from the disease. Because once you suffer from cancer, the use of radiotherapy, chemotherapy and other methods are likely to damage the reproductive organs, affect the production of male or female hormones, and cause the patient to be infertile.

Japanese Wagyu beef grown in laboratory using 3D bioprinting technology
According to the Global Times, Japanese scientists recently used 3D printing technology to successfully create Wagyu beef with a marbled effect. The manufactured meat products contain protein, fat, and even blood vessels. Researchers say such "cultured" steaks are more environmentally friendly than their traditional counterparts. Wagyu is an expensive and highly sought-after beef breed from Japan.

Smaller than the diameter of a hair! New breakthroughs in the field of micro- and nano-robots
Not long ago, an international team including Chinese scientists developed a "miniature paper crane" that is smaller than the diameter of a hair. Under the influence of voltage, it can automatically fold from a flat surface in less than one second. As a new micro-actuator with a size of only tens of microns, this imaginative paper crane is another breakthrough in the field of micro-nano robot research and development.
