Making the case to ensure access to egg freezing is equitable

Latest Australian data indicates that the number of human egg-freezing cycles performed each year has increased more than 1000% from 2010 to 2019. Despite this, egg freezing remains prohibitively expensive, with a single cycle costing up to $10,000. Due to these costs, individuals may delay accessing egg freezing. This, however, comes at a biological cost, as the number of good-quality eggs decreases with age, meaning the chance of falling...

Bilingualism comes naturally to our brains, new study shows

The brain uses a shared mechanism for combining words from a single language and for combining words from two different languages, a team of neuroscientists has discovered. Its findings indicate that language switching is natural for those who are bilingual because the brain has a mechanism that does not detect that the language has switched, allowing for a seamless transition in comprehending more than one language at once.

Scientists discover how our brain uses nutritional state to regulate growth and age at puberty

Scientists have discovered how a receptor in the brain, called MC3R, detects the nutritional state of the body and regulates the timing of puberty and rate of growth in children and increases in lean muscle mass. These findings, published today in the journal Nature, may explain how humans have been growing taller and reaching sexual maturity earlier over the past century. Over the 20th century, average height increased by about 10 cm in the...
