Study urges caution when comparing neural networks to the brain
Neuroscientists often use neural networks to model the kind of tasks the brain performs, in hopes that the models could suggest new hypotheses regarding how the brain itself performs those tasks. But a group of MIT researchers urges that more caution should be taken when interpreting these models.

Suppressing a gene by using its antibody can lead to tooth growth: animal study
Tooth loss is a widespread problem in adults and results in poor quality of life. Currently, solutions to this problem include artificial teeth and implants. But these aren’t as good as “real teeth,” and they don’t markedly improve quality of life. Now, scientists from Japan have made a discovery that can make…
