Die. Reborn. F**k your genes!
Is the secret to long life in a gene? We don't know, for now. A recent project to read the entire DNA sequence of 17 people aged 110 or older has found… there's nothing particularly different from ordinary folks. It is known that super-longevity is inheritable. It runs in families. An analysis of twins suggests…

Psychology, ADHD, genes, dogmatism.
Psychologists have made a brain-related discovery that could revolutionize doctors' perception and treatment of attention-deficit disorders (ADHD). This discovery opens up the possibility that environmental and/or genetic factors may hinder or suppress a specific brain activity that the researchers have identified as helping us prevent distraction. (1) Free will sacrificed for the sake of gene-based…

Now a service that creates digital embryos by virtually mixing two people's DNA will give a clearer glimpse of their possible child's health, and perhaps much more – before it has been conceived. The Matchright technology will be available in two US…
