| 125-million-year-old mammal fossil reveals the early evolution of hair and spines Posted: 14 Oct 2015 10:45 AM PDT Discovered in Spain, the fossil of the newly described, 125-million-year old Spinolestes xenarthrosus is remarkably well-preserved, containing fur, hair follicles, hedgehog-like spines, organs and even a fungal skin infection. It pushes back the record of preserved mammalian hair and soft tissue by more than 60 million years. |
| Mathematicians find 'magic key' to drive Ramanujan's taxi-cab number Posted: 14 Oct 2015 10:24 AM PDT Taxi-cab numbers, among the most beloved integers in math, trace their origins to 1918 and what seemed like a casual insight by the Indian genius Srinivasa Ramanujan. Now mathematicians have discovered that Ramanujan did not just identify the first taxi-cab number -- 1729 -- and its quirky properties. He showed how the number relates to elliptic curves and K3 surfaces -- objects important today in string theory and quantum physics. |
| Larger brains do not lead to high IQs, new meta-analysis finds Posted: 14 Oct 2015 09:11 AM PDT Is brain size related to cognitive ability of humans? This question has captured the attention of scientists for more than a century. An international team of researchers provides no evidence for a causal role of brain size for IQ test performance. In a meta-analysis of data from more than 8000 participants, they show that associations between in vivo brain volume and IQ are small. |
| What smacks into Ceres stays on Ceres, research suggests Posted: 14 Oct 2015 07:59 AM PDT A new set of high-velocity impact experiments suggests that the dwarf planet Ceres may be something of a cosmic dartboard: projectiles that slam into it tend to stick. The findings could help explain characteristics of Ceres' surface. |
| Shedding light on the growth of stars and black holes Posted: 14 Oct 2015 06:03 AM PDT Astronomers have revealed a surprising similarity between the way in which astronomical objects grow including black holes, white dwarfs and young stars. |
| Exoskeleton to ensure an active old age Posted: 14 Oct 2015 05:54 AM PDT Researchers are creating portable robot skeletons for the elderly so they can continue to be active longer. Think of it as a tool, not as a robot, says researcher. |
| How perfect is too perfect? Research reveals robot flaws are key to interacting with humans Posted: 14 Oct 2015 05:51 AM PDT Humans are less likely to form successful working relationships with interactive robots if they are programmed to be too perfect, new research reveals. |
| What does it take to escape the water? Plankton have clues Posted: 14 Oct 2015 05:48 AM PDT Dolphins and whales may attract a lot of attention when they leap dramatically out of the water. But aquatic animals thousands of times smaller are accomplished jumpers, too.Their acrobatics often go unnoticed, but understanding them could help improve engineering processes, like oil refining and wastewater treatment, that rely on controlling the interaction of small particles with air-water interfaces. |
| Spectacular 'halos' of spiral galaxies Posted: 13 Oct 2015 10:55 AM PDT Astronomers have found the true extent of 'halos' consisting of cosmic rays and magnetic fields surrounding spiral galaxies. |
