How much do unborn babies sleep? (Things We Don’t Know about Pregnancy Series #16)
We can’t measure the brain activity of a human foetus – not whilst they’re inside their mother. But we’re really interested. What happens to a baby’s brain as it’s developing, and what does this tell us about our own and the developing process of sleep? Researchers into brain activity have performed EEG exams on premature babies, and monitored eye movement in the womb to learn about sleep cycles, although big errors are common. REM (rapid eye movement) sleep was detected from around

How does caesarean birth affect hormone levels like oxytocin, and maternal-infant bonding?

Climate change, glacial recession and mammal communities
Changing climates have impacted the cryosphere for millions of years, and massive ice sheets have repeatedly advanced and retreated throughout history. The recession and advancement of these walls of ice has had an enormous impact on landscapes and the distribution of species, and while there have been many studies investigating how historical glacial recession has impacted current species distribution, little is known about how current species distribution is impacted by present day glacial rec
