Sweet, soft solution to hard brain implants
Brain implants are used to treat neurological dysfunction, and their use for enhancing cognitive abilities is a promising field of research. Implants can be used to monitor brain activity or stimulate parts of the brain using electrical pulses. In epilepsy, for example, brain implants can determine where in the brain seizures are happening.
Over time, implants trigger a foreign body response, creating inflammation and scar tissue around the implant that reduces their effectiveness.
The problem is that traditional implants are much more rigid than brain tissue, which has a softness comparable to pudding. Stress between the implant and the tissue caused by constant movement of the brain with respect to the implant signals the body to treat the implant as a foreign object. This interaction between the implant and the brain is similar to a knife cutting into a piece of pudding. An implant as soft as brain tissue would be ideal, but such soft

MONTREAL A 54-year-old woman has died in the province after receiving the AstraZeneca COVID-19 vaccine, Quebec s public health director Horacio Arruda confirmed Tuesday. “We just had our first patient who has died of a thrombosis, cerebral thrombosis, following vaccination from AstraZeneca, said Arruda in a news conference. This is an event that is rare. We knew that it might happen. We have a risk of default one in every 100,000 doses today. Arruda said it was a risk the province knew it was taking, and that the benefits outweigh the risks. It puts a face on a statistic and for us, statistics are always people, and there s no way of knowing who the person is who is going to react that way, he added. People don t get vaccinated to die. It s rare, and we can t predict it. But for the population at large, vaccination remains beneficial.
