Taste of a fetus Babies whose mothers consumed garlic or anise during pregnancy are drawn towards those smells in the first few days after birth: we investigate how flavours get into the amniotic fluid
SPACE
Sound of the ‘little bang’ Smashing gold ions together in particle accelerators can create matter as hot and dense as just after the big bang. Now physicists have calculated what such “little bangs” sound like
INNOVATION
‘White spaces’ could extend range of internet hotspots A new breed of wireless routers tuned to unused TV frequency bands could keep users attached to their domestic broadband connection hundreds of metres from their homes
