| Babies time their smiles to make their moms smile in return Posted: 23 Sep 2015 12:14 PM PDT Why do babies smile when they interact with their parents? Could their smiles have a purpose? A team of computer scientists, roboticists and developmental psychologists confirm what most parents already suspect: when babies smile, they do so with a purpose -- to make the person they interact with smile in return. To verify their findings, researchers programmed a toddler-like robot to behave like the babies they studied and had the robot interact with undergraduate students. |
| Team links two human brains for question-and-answer experiment Posted: 23 Sep 2015 12:13 PM PDT Researchers used a brain-to-brain interface they developed to allow pairs of participants to play a '20 question' style game by transmitting signals from one brain to another over the Internet. Their experiment is thought to be the first to demonstrate that two brains can be directly linked to allow someone to accurately guess what is on another person's mind. |
| 9,000-year-old ritualized decapitation found in Brazil Posted: 23 Sep 2015 12:13 PM PDT A 9,000-year-old case of human decapitation has been found in the rock shelter of Lapa do Santo in Brazil. |
| Giant killer lizard fossil shines new light on early Australians Posted: 23 Sep 2015 10:41 AM PDT As if life wasn't hard enough during the last Ice Age, a new study has found Australia's first human inhabitants had to contend with giant killer lizards. Researchers working in Central Queensland were amazed when they unearthed the first evidence that Australia's early human inhabitants and giant apex predator lizards had overlapped. |
| Enamel evolved in the skin and colonized the teeth much later Posted: 23 Sep 2015 10:34 AM PDT When did the enamel that covers our teeth evolve? And where in the body did this tissue first appear? In a new study, researchers combined data from two very different research fields -- paleontology and genomics -- to arrive at a clear but unexpected answer to this question: enamel originated in the skin and colonized the teeth much later. |
| How to find out about the human mind through stone Posted: 23 Sep 2015 07:34 AM PDT Researchers are looking at flint flakes to study laterality in Palaeolithic humans, in other words, which hand they used to fashion their artefacts. Laterality is the preference of human beings for one side of our bodies; being left-handed or right-handed, for example, or having a preference for using one eye or ear or the other. |
| Hot, dense material surrounds O-type star with largest magnetic field known Posted: 23 Sep 2015 05:26 AM PDT Observations revealed that the unusually large magnetosphere around an O-type star called NGC 1624-2 contains a raging storm of extreme stellar winds and dense plasma that gobbles up X-rays before they can escape into space. |
| Fish 'backpack' advances underwater research Posted: 22 Sep 2015 07:14 PM PDT A new underwater stimulation system has been designed to study electrical activity in certain aquatic animals. Though common in studies of land animals and insects, the form of electrical manipulation that this device allows is unprecedented in underwater research, due to environmental limitations like equipment corrosion and accessibility. |
| Quantum teleportation: World record of 100 kilometers Posted: 22 Sep 2015 08:47 AM PDT Researchers have 'teleported' or transferred quantum information carried in light particles over 100 kilometers (km) of optical fiber, four times farther than the previous record. |
