Robotic Dentistry

Medical robots are being put into practice as they can help increase safety, quality and precision for medical professionals. Robotic technology is always advancing and a wide range of robots are being developed to suit roles in the medical environment. These are some examples of robotic technology being used in dentistry. Dental Implant Robot In 2017, a robotic dentist fitted two dental implants into a woman’s mouth in china. Medical staff were present during the operation and programmed the robot’s movements but did not intervene in the surgery. The 3D printed teeth were fitted within a margin of error 0.2-0.3 mm, which is standard for implant surgery. China has a shortage of qualified dentists so robotic dentistry would help meet the demand. Robotic dentistry could also help reduce the risk of human-made errors. Yomi US company (Neocis) announced last year that the US Food & Drug Administration had given clearance for them to introduce the first robotically assisted ...

Mammalian sexual reproduction- Two mother mice and their healthy biological offspring

We all know of the classical model of sexual reproduction- The haploid chromosome sets of paternal and maternal gametes fuse together after 5 minutes of a steamy, unprotected tango, to form a diploid cell. This diploid cell then undergoes mitosis until we get the formation of a totipotent mass of embryonic stem cells. But what if possibilities existed outside of the natural order? What if it doesn’t necessarily ‘take a man and a woman’? What if it we could procreate using two unisex haploid cells and a fancy laboratory? On Thursday October 11th 2018 the Chinese Academy of Science made a breakthrough in field of sexual reproduction. The terms Parthenogenesis and Androgenesis refer to the formation of an embryonic stem cell from solely respectively maternal or paternal DNA. Rare in nature and near non-existent amongst mammals, this is how the Chinese Academy of Science managed to produce generations of both bimaternal and bipaternal mice. How modern humanity replicates Parthenogenesis ...
