Researchers at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are investigating the possibility of partially restoring sight to the blind by using a device known as an optic nerve implant (ONI). The device works by bypassing the eyeball and sending electrical signals directly to the optic nerve, the pathway through which visual information reaches the brain.
A report released in 2017 found that over half of all global emissions since 1988 have been produced by just 25 companies. When you take into account the 100 most environmentally damaging companies, known as the ‘Carbon Majors’, that figure rises to over 70%. Even so, we are constantly told that individual actions like using canvas bags and taking the bus will be enough to avoid the catastrophic effects of climate change. The truth is that the onus is on the major greenhouse gas emitters like Exxon Mobil and Shell Oil to simply stop extracting and distributing fossil fuels. Unfortunately, the pressures of the competitive market mean that they are not going to do this without a push.
Every minute, the equivalent of a truckload of plastic enters the sea. Since 2004, humans have produced more plastic than we did in the previous 50 years combined. As the global population rises, our need for cheap and sturdy materials rises with it. The problem with plastics is that they are too sturdy. Every piece of plastic ever produced still exists somewhere in the world. Once the plastic has finally disintegrated, that is by no means the end of the problem. Plastics in the ocean break down into tiny particles known as microplastics. Such particles are found throughout marine ecosystems; from the stomachs of fish, to the stomachs of the seabirds who eat them.
Hence, geneticists worldwide have called for a moratorium on human germline trials. Critics say that gene editing technology has not yet been developed or tested sufficiently for use on human embryos. We simply do not yet know the long-term effects of genetic modification using CRISPR.
