Controversial insecticides shown to threaten survival of wild birds Posted: 12 Sep 2019 11:04 AM PDT New research shows how the world's most widely used insecticides could be partly responsible for dramatic declines in farmland bird populations. In the first experiment to track effects of a neonicotinoid pesticide on birds in the wild, the team found that white-crowned sparrows who consumed small doses of imidacloprid insecticide suffered weight loss and delays to their migration -- effects that could severely harm the birds' chances of surviving and reproducing. |
Why is Earth so biologically diverse? Mountains hold the answer Posted: 12 Sep 2019 11:04 AM PDT Life on Earth is amazingly diverse, and exhibits striking geographical global patterns in biodiversity. A pair of companion papers reveal that mountain regions -- especially those in the tropics -- are hotspots of extraordinary and baffling richness. Although mountain regions cover only 25% of Earth's land area, they are home to more than 85% of the world's species of amphibians, birds, and mammals, and many of these are found only in mountains. |

How a carbon-fixing organelle forms via phase separation Posted: 12 Sep 2019 10:44 AM PDT Algae remove vast amounts of carbon dioxide from the atmosphere during photosynthesis thanks to an organelle called the pyrenoid, which boosts the efficiency of carbon-fixation. Researchers have known that the pyrenoid forms via a process of phase separation, the same process that causes oil to cluster into droplets in water. The new study looks deeper into how this happens. |
Elaborate Komodo dragon armor defends against other dragons Posted: 12 Sep 2019 10:43 AM PDT Just beneath their scales, Komodo dragons wear a suit of armor made of tiny bones. These bones cover the dragons from head to tail, creating a 'chain mail' that protects the giant predators. However, the armor raises a question: What does the world's largest lizard -- the dominant predator in its natural habitat -- need protection from? |
'Fire inversions' lock smoke in valleys Posted: 12 Sep 2019 10:43 AM PDT There's an atmospheric feedback loop, says an atmospheric scientist, that can lock smoke in valleys in much the same way that temperature inversions lock the smog and gunk in the Salt Lake Valley each winter. But understanding this loop can help scientists predict how smoke will impact air quality in valleys, hopefully helping both residents and firefighters alike. |

Microbes are degrading infrastructure, compounding health implications Posted: 12 Sep 2019 07:09 AM PDT Microorganisms growing inside aging buildings and infrastructure are more than just a health issue, according to new research. The research examined the impact of fungal mold growth and associated microbes within structures on a university campus. The study focuses on the observed biodeteriorative capabilities of indoor fungi upon gypsum board material (drywall) and how it affects a building's age and room functionality. |

Sulphur emissions from marine algae dropped during glacial periods Posted: 12 Sep 2019 07:09 AM PDT Contrary to conventional wisdom, sulphur production by tiny marine algae decreased during glacial periods, and is more closely linked to climate than previously thought, according to latest research. A clearer understanding of the link between the climate and marine phytoplankton can help scientists incorporate these impacts in future climate models. |
Growing citrus disease bacteria in the lab Posted: 12 Sep 2019 06:47 AM PDT Being able to grow the elusive and poorly understood bacterium, Candidatus Liberibacter asiaticus (CLas), will make it easier for researchers to find treatments for the disease that has destroyed millions of acres of orange, grapefruit and lemon groves around the world and has devastated the citrus industry in Florida. |
Terahertz waves reveal hidden processes in ultrafast artificial photosynthesis Posted: 12 Sep 2019 06:47 AM PDT Researchers have succeeded in observing charge transfer and intermolecular interactions in ultrafast artificial photosynthesis. A new finding will help to develop highly efficient photocatalytic reactions, and TR-ATR terahertz spectroscopy will assist research on biological and chemical reaction processes. |
