| Tiny birds ‘cry hawk’ to give offspring chance to escape predators Posted: 02 Jun 2015 05:04 PM PDT New research has found that the 6 gram brown thornbill mimics the hawk alarm calls of neighboring species to scare a nest predator by convincing it that a much bigger and scarier predator -- the brown goshawk -- is on its way.  |
| Deepest high-temperature hydrothermal vents discovered in Pacific Ocean Posted: 02 Jun 2015 02:19 PM PDT Researchers have discovered a large, previously unknown field of hydrothermal vents in the Gulf of California, about 150 kilometers (100 miles) east of La Paz, Mexico. Lying more than 3,800 meters (12,500 feet) below the surface, the Pescadero Basin vents are the deepest high-temperature hydrothermal vents ever observed in or around the Pacific Ocean.  |
| Posted: 02 Jun 2015 12:34 PM PDT Scientists used streams produced by dissolving globular clusters to measure the weight of our galaxy and determine the location of the sun within the Milky Way.  |
| Toothbrush contamination in communal bathrooms Posted: 02 Jun 2015 10:06 AM PDT Data confirms that there is transmission of fecal coliforms in communal bathrooms at a university, and that toothbrushes can serve as a vector for transmission of potentially pathogenic organisms.  |
| Intelligent bacteria for detecting disease Posted: 02 Jun 2015 10:05 AM PDT Research teams have transformed bacteria into 'secret agents' that can give warning of a disease based solely on the presence of characteristic molecules in the urine or blood. To perform this feat, the researchers inserted the equivalent of a computer program into the DNA of the bacterial cells. The bacteria thus programmed detect the abnormal presence of glucose in the urine of diabetic patients. This work is the first step in the use of programmable cells for medical diagnosis.  |
| Microbiology: Gut bacteria cooperate when life gets tough Posted: 02 Jun 2015 10:00 AM PDT Researchers have discovered with the help of computer models how gut bacteria respond to changes in their environment -- such as a decrease in oxygen levels or nutrient availability. Microorganisms that normally compete or overthrow one another can switch to a cooperative lifestyle when their living conditions change: They even start producing substances to make life easier for the other species, helping them to survive. The entire microbial community then stabilizes -- and together adapts successfully to the new situation.  |
| Earth organisms survive under low-pressure Martian conditions Posted: 02 Jun 2015 09:58 AM PDT Methanogens -- among the simplest and oldest organisms on Earth -- could survive on Mars, new research suggests. Methanogens, microorganisms in the domain Archaea, use hydrogen as their energy source and carbon dioxide as their carbon source, to metabolize and produce methane, also known as natural gas. Methanogens live in swamps and marshes, but can also be found in the gut of cattle, termites and other herbivores as well as in dead and decaying matter.  |
