| Astronomers create first realistic virtual universe Posted: 07 May 2014 11:28 AM PDT Move over, Matrix - astronomers have done you one better. They have created the first realistic virtual universe using a computer simulation called 'Illustris.' Illustris can recreate 13 billion years of cosmic evolution in a cube 350 million light-years on a side with unprecedented resolution. |
| Posted: 07 May 2014 10:23 AM PDT Scientists have reported the unique discovery of the marine dinoflagellate Dapsilidinium pastielsii from Southeast Asia, notably the Indo-Pacific Warm Pool (IPWP). This unicellular species, with planktonic and benthic stages, was previously thought to have become extinct within the early Pleistocene. It evolved more than 50 million years ago and is the last survivor of a major early Cenozoic lineage. |
| Posted: 07 May 2014 10:21 AM PDT Scientists have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature; the bacterium's cells can replicate the unnatural DNA bases more or less normally, as long as the molecular building blocks are supplied. |
| Mapping the spider genome: Surprising similarities to humans Posted: 07 May 2014 07:50 AM PDT For the first time ever, a group of researchers has sequenced the genome of the spider. This knowledge provides a much more qualified basis for studying features of the spider. It also shows that humans share certain genomic similarities with spiders. However, the sequencing has far greater significance for our future understanding of the spider's special properties. The researchers worked with two types of spiders, representing two of the three main groups in the spider family. One of these is a small velvet spider and the other is a tarantula. |
| Sprites form at plasma irregularities in the lower ionosphere Posted: 07 May 2014 07:04 AM PDT Atmospheric sprites have been known for nearly a century, but their origins were a mystery. Now, a team of researchers has evidence that sprites form at plasma irregularities and may be useful in remote sensing of the lower ionosphere. |
| Emotional arousal makes us better at swearing Posted: 06 May 2014 05:40 PM PDT People swear more colorfully when they are in a emotionally aroused state. This suggests that swearing is closely related to emotion. |
| Shrinking helped dinosaurs and birds to keep evolving Posted: 06 May 2014 04:07 PM PDT Although most dinosaurs went extinct 65 million years ago, one dinosaur lineage survived and lives on today as a major evolutionary success story -- the birds. A study that has 'weighed' hundreds of dinosaurs suggests that shrinking their bodies may have helped the group that became birds to continue exploiting new ecological niches throughout their evolution, and become hugely successful today. |
