Xenotransplantation is the transplanting of cells, tissues or organs from animals to humans. Pre-clinical trials of organ transplant from pigs have addressed some of the technical barriers.
New developments in organ transplants from animals show promise. However, there has been no public engagement about a potential risk. It may streamline a pathway to humans for new zoonotic diseases.
The rapid rate of species declines means we should trial potential solutions before it’s too late.
New research in fruit flies elucidates how the genes that direct animal body shape work.

Hox genes make sure all your body parts grow in the right place. Understanding how they work can reveal the process of evolution and lead to potential treatments for congenital birth defects.
Field trials of genetically edited crop plants are to be allowed in England under new government proposals.
Catherine Price, sociologist, and Nicola Patron, synthetic plant biologist, discuss the promises, dangers and concerns around gene edited and GM crops.
Crystal jellyfish contain glowing proteins that scientists repurpose for an endless array of studies.

Three pioneering technologies have forever altered how researchers do their work and promise to revolutionize medicine, from correcting genetic disorders to treating degenerative brain diseases.
A global treaty bans research or stockpiling of biological weapons — but allows bioweapon defense planning.

The sketchy history of international efforts to control bioweapons suggests that nations will resist cooperative monitoring of gene hacking for medical research.
Researchers have grown mammal embryos later into development than ever before in an artificial womb.
Researchers have grown the first human-monkey hybrid embryos as well as mouse embryos in artificial wombs late into development. These biomedical breakthroughs raise different ethical quandaries.
RNA carries copies of genetic information from DNA.
RNA was used to make COVID vaccines. Now it could lead to more personalised healthcare.

As the world has focused on the COVID-19 pandemic, other microbial foes are waging war on humans. Antibiotic-resistant bacteria pose a growing threat. But viruses may defeat them.
Any man-made changes to the human genome must be carefully regulated.
We propose five principles that could guide a proper ethical and legal framework for germline editing and similar technologies.
Using ‘base editing’, researchers have cured progeria in mice. This genetic syndrome causes premature ageing in humans – those with the disease usually don’t live past the age of 13.
Margaret Atwood gives a talk at a Walrus magazine event in Toronto on June 14, 2016.
Canada has produced Nobel Prize winners in the arts and sciences. With several recent awards, Canadian talent still has the potential for future achievements.
We could edit our genes to make us more resistance to viruses.
We could start making our genomes equipped to deal with more frequent pandemics. But it may come at a cost.

The tools to rewrite the genetic code to improve crops and livestock, or to treat genetic diseases, has revolutionized biology. A CRISPR engineer explains why this technology won the Nobel, and its potential.
CRISPR enables editing DNA with unprecedented precision.
