It’s further than anyone has ever gone with gene editing in the United States.
A team working at the Francis Crick Institute in London applied to the Human Fertilisation and Embryology Authority for a permit that would allow them to edit genes in a human embryo. If allowed, this would lead to the very first genetically modified embryo in the UK. The scientists claim they need approval to do basic research that may ” improve embryo development after in vitro fertilization (IVF) and might provide better clinical treatments for infertility,” and not for clinical research. Either way, the controversial practice is banned in all Western countries and virtually banned, although not explicitly, in the US.
The US National Institutes of Health (NIH) has reiterated its stance against modifying human embryos, after a paper published last week by Chinese researchers reported how they modified the DNA of human embryos to eradicate certain inheritable diseases from the lineage. Modifying human embryos was banned in 1996 for US government bodies, but in some states private entities are allowed to carry out such research.
If you’ve ever wondered what happens inside an egg, then science has you covered – researchers have developed transparent artificial eggshells; but they didn’t do this just out of curiosity – they want to create a controlled environment for bird embryo growth and development to aid stem cell studies.
A breakthrough study authored by Harvard University developmental biologists has finally resolved the mystery of how sexual organs appeared for the first time in vertebrates. According to their findings, shortly after our sea-dwelling ancestors migrated on land, creatures were pressured to quickly evolve genitalia – which they didn’t require up until then. These sexual organs, at least for snakes and lizards, originated
Child birth is a momentous occasion in all human cultures across the globe, and if you’ve ever witnessed one it’s easy to understand why. A new life enters the world, but the journey stars well before labor. Here‘s an incredible photo gallery showcasing a typical fetal development from ovary implantation to its final chapter.
A new visualization technique developed by researchers at the Howard Hughes Medical Institute used a thin sheet of laser light that beams, stepwise, into different planes of a specimen to create intricate and detailed snapshots of cells. In these pictures featured above and below you can see how zebrafish and fruit fly embryos were imaged using this novel technique. Here’s how it all
Sharks are the ultimate predators, comfortably sitting at the very top of the food chain; but even they have their enemies (the biggest one being us, of course), especially when they’re small – nobody fears a small shark. But even in their defenseless period, sharks have managed to find a way to adapt. Australian researchers found that the embryos know
British scientists have received the green light to research devastating diseases such as Alzheimer’s and Parkinson’s using human-animal embryos, after the House of Commons rejected a ban yesterday. Already a wave of contradictions and the scientific world is divided into two camps. An amendment to the Human Fertilisation and Embryology Bill was rejected in a free vote, preserving
