| Microbes help beetles defeat plant defenses Posted: 09 Sep 2013 02:22 PM PDT Some symbiotic bacteria living inside Colorado potato beetles can trick plants into reacting to a microbial attack rather than that of a chewing herbivore, according to a researchers who found that the beetles with bacteria were healthier and grew better. |
| New camouflage coating fabricated from squid protein Posted: 09 Sep 2013 02:22 PM PDT What can the US military learn from a common squid? A lot about how to hide from enemies, according to researchers. |
| Butterfly wings inspire new technologies: From fabrics and cosmetics to sensors Posted: 09 Sep 2013 02:22 PM PDT A new study has revealed that the stunning iridescent wings of the tropical blue Morpho butterfly could expand the range of innovative technologies. Scientific lessons learned from these butterflies have already inspired designs of new displays, fabrics and cosmetics. |
| Indy 500 race cars showcase green fuels Posted: 09 Sep 2013 01:20 PM PDT Mention cars that get barely 3 miles to a gallon and are built for speed rather than cleanliness, and images of gas-guzzling, pollution-belching menaces burning leaded gasoline or nitro may spring to mind. But experts today described how ethanol blends used as fuel in the race cars of the Indianapolis 500 actually make those emissions cleaner than cars on the street. |
| Breaking deep-sea waves, as high as a skyscraper, reveal mechanism for global ocean mixing Posted: 09 Sep 2013 12:29 PM PDT Oceanographers for the first time recorded an enormous wave breaking miles below the surface in a key bottleneck for global ocean circulation. |
| Rainfall in South Pacific was more variable before 20th century Posted: 09 Sep 2013 12:29 PM PDT A new reconstruction of climate in the South Pacific during the past 446 years shows rainfall varied much more dramatically before the start of the 20th century than after. The finding, based on an analysis of a cave formation called a stalagmite from the island nation of Vanuatu, could force climate modelers to adjust their models. |
| Researchers read the coffee grounds and find a promising energy resource for the future Posted: 09 Sep 2013 12:29 PM PDT What's usually considered old garbage might be a promising asset for our energy supply, according to researchers. |
| New ten second sourcing technology set to transform archaeology Posted: 09 Sep 2013 09:19 AM PDT Researchers have developed a method of sourcing obsidian artifacts that takes only 10 seconds -- dozens of times faster than the current methods -- with a handheld instrument that can be used at archaeological excavations. |
| Ancient golden treasure found at foot of Temple Mount Posted: 09 Sep 2013 09:19 AM PDT In summer excavations at the foot of the Temple Mount, archaeologists made a stunning discovery: two bundles of treasure containing thirty-six gold coins, gold and silver jewelry, and a gold medallion with the menorah (Temple candelabrum) symbol etched into it. Also etched into the 10-cm medallion are a shofar (ram's horn) and a Torah scroll. |
| How bedbugs shrug off pesticides and simple measures to deal with it Posted: 09 Sep 2013 09:18 AM PDT The bedbug's most closely guarded secrets — stashed away in protective armor that enables these blood-sucking little nasties to shrug off insecticides and thrive in homes and hotels. The talk includes implications for millions of people trying to cope with bed bug infestations that have been resurging for more than a decade. |
| Surprising underwater-sounds: Humpback whales also spend their winter in Antarctica Posted: 09 Sep 2013 08:12 AM PDT Biologists and physicists have discovered that not all of the Southern Hemisphere humpback whales migrate towards the equator at the end of the Antarctic summer. |
| Scientists calculate the energy required to store wind and solar power on the grid Posted: 09 Sep 2013 07:52 AM PDT Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution. But a new study finds that when you factor in the energetic costs, grid-scale batteries make sense for storing surplus solar energy, but not for wind. |
| Artificial lung to remove carbon dioxide -- from smokestacks Posted: 09 Sep 2013 07:47 AM PDT After studying the functioning of the lungs of birds and the swim bladders of fish, scientists described how they created an improved method to capture carbon dioxide that acts like a reverse natural lung, breathing in the polluting gas. Their study details the best way to arrange tubes in a carbon dioxide capture. |
| Recycled sewage water is safe for crop irrigation, study suggests Posted: 09 Sep 2013 07:47 AM PDT The first study under realistic field conditions has found reassuringly low levels of chemicals from pharmaceuticals and personal care products in crops irrigated with recycled sewage water, scientists have reported. |
