Antibiotic resistant bacterium uses Sonar-like strategy to 'see' enemies or prey
...According to Gilmore, "These bacteria are actively probing their environment for enemies or food. Based on whether or not they 'see' other cells, they make the toxin appropriately." Gilmore says this discovery has several significant implications for the future. "This is a new mechanism that nature devised t...Body's biological clock found to affect cardiac rhythm patterns in healthy adults
...ics methods to investigations of cardiac dynamics, probing for hidden patterns. Previous statistical evaluations of heartbeat fluctuations by Ivanov and others have shown that those of healthy subjects exhibit a self-similar structure over a range of time scales, that is, the fluctuations found in a window ...Discovery of first demethylase molecule, a long-sought gene regulator
...hunt, but they stumbled onto the demethylase while probing the function of a new gene repressor protein. Postdoctoral fellow Yujiang Shi had exhausted the likely possibilities for how the mystery protein worked to suppress gene activity, so one day he tried an unlikely experiment. He had the purified protein...Science's Breakthrough of the Year: Salty, acidic soup could have supported life on Mars
...ensate" under their belts, researchers got down to probing these strange forms of matter in 2004. They learned how condensates' behavior changes as atoms grow further apart, and they created a solid condensate, complementing earlier successes with gas and liquid versions.

...ace of honour by the front door, Dr. Ross says her probing has revealed another floral first that's "really going to shake things up" in the world of plant reproduction science. The male portion of the dwarf mistletoe sends out its pollen tube prematurely (or pre-emptively, depending on your interpr...Award-winning INEEL probe to help safely monitor hazardous waste sites
