Embryos for spare parts: it's time to discuss the problem

In England, a debate is raging about whether it is permissible to use embryos to obtain stem cells. Scientists believe that in 10 years stem cells can be used to treat various diseases. In addition, embryos can be used to grow new organs – "spare parts" for the body.

Nanofiber tendons

To create artificial tendons, Bosworth twisted a biodegradable nanofiber in a special way, which can be implanted into the human body. The resulting "tissue" is similar in structure to the natural one and can be transplanted to the site of the rupture. It will promote fusion, and the artificial polymer replacement will gradually disappear, and its own connective tissue will form in its place.

Cell reprogramming: proteins instead of genes

In their publication, the scientists note that the "protein-induced pluripotent stem cells" they obtained, like their classical counterparts, are able to transition back into a specific state and form the tissues of developing mouse embryos.

The cow genome has been sequenced

The first paper describes the results of work on reading the complete genome of a cow of the famous Hereford breed selected for sequencing. In the second – the results of a side project that cost a hundred times less – comparison of the genome of almost 500 cows of 19 different breeds for 37740 single-nucleotide polymorphisms ("snips").

The world's first transgenic puppies glow red

The first cloned puppy was born in 2005, and dogs have been cloned more than once since then, but now, before the transfer of the nucleus, the fibroblast culture was infected with a modified retrovirus with an embedded gene of the red fluorescent anemone protein. Five glowing dogs feel good and glow like Kremlin stars under an ultraviolet lamp.
