| Do black holes come in size medium? Posted: 29 Nov 2013 06:11 PM PST Black holes can be petite, with masses only about 10 times that of our sun -- or monstrous, boasting the equivalent in mass up to 10 billion suns. Do black holes also come in size medium? NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is busy scrutinizing a class of black holes that may fall into the proposed medium-sized category.  |
| Controversy over use of Roman ingots to investigate dark matter, neutrinos Posted: 29 Nov 2013 07:19 AM PST The properties of lead bricks recovered from ancient shipwrecks are ideal for experiments in particle physics. Scientists have begun to use them, but archaeologists have raised alarm about the destruction and trading of cultural heritage that lies behind this.  |
| The more the better: Polyandry in salamanders Posted: 29 Nov 2013 07:18 AM PST New research shows the impact of polyandry on reproductive success in fire salamanders.  |
| Mitochondria separate their waste Posted: 29 Nov 2013 07:18 AM PST Cellular power plants collect and break down damaged molecules in order to protect themselves from harmful substances, research shows. Up to now, it was unclear whether this housekeeping work involves sorting out defective proteins when they digest mitochondria. Researchers have now discovered that the proteins are sorted out during the constant fusion and fission of mitochondria.  |
| Telescope to track space junk using youth radio station Posted: 29 Nov 2013 07:18 AM PST A combination of pop songs, talkback radio and cutting-edge science has enabled Australian astronomers to identify a way to prevent catastrophic, multi-billion dollar space junk collisions, a new study has revealed.  |
| Electricity generated from weight of traffic and pedestrians Posted: 29 Nov 2013 07:17 AM PST New technology integrates a ramp-step (elaborated with polymeric material similar to the ones used in the manufacture of tires) that elevates to five centimeters above the level of the street. When receiving the impact of a vehicle, this ramp exerts pressure on a set of bellows below. The bellows contain air that is expelled at a certain pressure through a hose; later, this element travels to a tank where it is compressed and relaunched to an electricity generating turbine.  |
| Food fight or exercise attack? Posted: 29 Nov 2013 07:16 AM PST Experts offer two ways to battle the holiday bulge.  |
| Bone grafting improvements with help of sea coral Posted: 28 Nov 2013 09:59 PM PST Sea coral could soon be used more extensively in bone grafting procedures thanks to new research that has refined the material's properties and made it more compatible with natural bone.  |
| Snapshots differentiate molecules from their mirror image Posted: 28 Nov 2013 11:13 AM PST Researchers are able to reveal the spatial structure of chiral molecules from work done to develop a method that takes a snapshot of chiral molecules, revealing their spatial atomic structure. The molecule's handedness, or chirality, can be directly derived from this information.  |
