| Research uncovers connection between Craigslist personals, HIV trends Posted: 30 Jan 2015 10:28 AM PST Craigslist's entry into a market results in a 15.9 percent increase in reported HIV cases, according to research. When mapped at the national level, more than 6,000 HIV cases annually and treatment costs estimated between $62 million and $65.3 million can be linked to the popular website, the authors state. |
| Why do zebras have stripes? Temperature counts Posted: 30 Jan 2015 06:29 AM PST One of nature's fascinating questions is how zebras got their stripes. A team of life scientists has found at least part of the answer: The amount and intensity of striping can be best predicted by the temperature of the environment in which zebras live. |
| Skip the dip! Super Bowl team cities see spike in flu deaths Posted: 30 Jan 2015 06:27 AM PST Having a team in the Super Bowl correlated to an average 18 percent increase in flu deaths among those over 65 years old, according to a study of health data covering 35 years of championship games. |
| Water purification: Running fuel cells on bacteria Posted: 30 Jan 2015 05:15 AM PST Researchers in Norway have succeeded in getting bacteria to power a fuel cell. The "fuel" used is wastewater, and the products of the process are purified water droplets and electricity. This is an environmentally-friendly process for the purification of water derived from industrial processes and suchlike. It also generates small amounts of electricity – in practice enough to drive a small fan, a sensor or a light-emitting diode. In the future, the researchers hope to scale up this energy generation to enable the same energy to be used to power the water purification process, which commonly consists of many stages, often involving mechanical and energy-demanding decontamination steps at its outset. |
| Unprecedented Dr-Jekyll-and-Mr-Hyde type of behaviour of aphids towards ants discovered Posted: 28 Jan 2015 07:06 AM PST Unprecedented interaction between aphids and ants that reveals how the first group of insects may display a Dr-Jekyll-and-Mr-Hyde type of behaviour towards the second group has been identified by researchers. Traditionally, aphids and ants have had a relationship based on cooperativism. However, after more than 50 hours of recording different anthills through a microscopy, this research has revealed that a certain species of aphids produces individuals which are adopted in the ant's brood chamber and they end up being aggressive to them by sucking haemolymph from their larvae. |
