| Out of an hours-long explosion, a stand-in for the first stars Posted: 11 Jul 2014 12:33 PM PDT Astronomers analyzing a long-lasting blast of high-energy light observed in 2013 report finding features strikingly similar to those expected from an explosion from the universe's earliest stars. If this interpretation is correct, the outburst validates ideas about a recently identified class of gamma-ray burst and serves as a stand-in for what future observatories may see as the last acts of the first stars.       |
| Non-invasive urine test could be used to predict premature birth, delivery of small babies Posted: 11 Jul 2014 06:21 AM PDT Testing for the presence of specific molecules present in the urine of pregnant women can give an indication in early pregnancy of whether a baby will be born premature or the fetus will suffer poor growth, according to research. Identifying these conditions early in pregnancy could potentially help reduce complications and manage any difficulties, although more work is needed before the findings can be translated to clinical settings.  |
| Scorpions are master architects, according to new research Posted: 10 Jul 2014 01:15 PM PDT The burrows made by scorpions follow a very sophisticated design, beginning with a short, vertical entrance shaft that flattened out a few centimeters below the surface into a horizontal platform, new research has found. The burrows then turn sharply downwards, descending further below ground to form a dead-end chamber. This cool, humid chamber, where evaporation water loss is minimal, provides a refuge for the scorpions to rest during the heat of the day.  |
| Ocean's most abundant organisms have clear daily cycles Posted: 10 Jul 2014 11:15 AM PDT In every drop of ocean water, hundreds of types of bacteria can be found. Now scientists have discovered that communities of these ocean microbes have their own daily cycles -- not unlike the residents of a bustling city who tend to wake up, commute, work, and eat at the same times. What's more, it's not all about the sun. These bacteria have been observed turning on diel cycling genes at slightly different times -— suggesting a wave of transcriptional activity that passes through the microbial community each day.  |
