| Cosmic swirly straws: Galaxies fed by funnels of fuel Posted: 24 May 2013 12:48 PM PDT Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws. The results show that cold gas -- fuel for stars -- spirals into the cores of galaxies along filaments, rapidly making its way to their "guts." Once there, the gas is converted into new stars, and the galaxies bulk up in mass. |
| Monkey teeth help reveal Neanderthal weaning Posted: 24 May 2013 07:48 AM PDT Most modern human mothers wean their babies much earlier than our closest primate relatives. But what about our extinct relatives, the Neanderthals? A team of U.S. and Australian researchers reports that they can now use fossil teeth to calculate when a Neanderthal baby was weaned. The new technique is based in part on knowledge gained from studies of teeth from human infants and from monkeys. |
