How do brains convert experiences into memories? New research explores the chain of events by focusing on what genes shift into gear when neurons are firing.
DNA sequencing means a scientist can take a bucket of seawater and ID every fish in the area. Now we need a universal ‘biobank’ of samples to make a truly powerful environment monitoring tool.
Separating children from their parents is not just a psychological stress, it’s a DNA stress. Scientific research shows that early life stress may have irreversible effects on how DNA works in the cells of the body.
Data and privacy issues are tangled up in the DNA reports consumers get from big genetic testing companies – and the third-party sites they turn to in order to glean more from their raw DNA.
The first people to make it to Australia could have navigated their way by sea crossing, reaching the north-west coastline of the island continent more than 50,000 years ago.
More people are sending off saliva samples to find out about their genetic roots. But the raw DNA results go way beyond genealogical data – and could deliver unintended consequences.
