Atmospheric rivers, cloud-creating aerosol particles, and california reservoirs

Posted: 17 Jan 2015 07:42 AM PST

In the midst of the California rainy season, scientists are embarking on a field campaign designed to improve the understanding of the natural and human-caused phenomena that determine when and how the state gets its precipitation. They will do so by studying atmospheric rivers, meteorological events that include the famous rainmaker known as the Pineapple Express.

Predicting coral reef futures under climate change

Posted: 14 Jan 2015 11:05 AM PST

Researchers examining the impact of climate change on coral reefs have found a way to predict which reefs are likely to recover following bleaching episodes and which won't. Coral bleaching is the most immediate threat to reefs from climate change; it's caused when ocean temperatures become warmer than normal maximum summer temperatures, and can lead to widespread coral death.

Iron overload disease causes rapid growth of potentially deadly bacteria

Posted: 14 Jan 2015 09:11 AM PST

The bacteria Vibrio vulnificus, found in warm saltwater, can cause people to get sick, or die, after they eat raw tainted shellfish or when an open wound comes in contact with seawater. A new study finds out not only why this potentially deadly bacteria is so dangerous in iron overload disease but also discovers that it can be cured.

New non-destructive device measures root growth in smaller plants

Posted: 14 Jan 2015 08:55 AM PST

An apparatus called the mini-Horhizotron was used to measure plant root growth in greenhouse settings. The device has three chambers that can be filled with the same or different substrates or treatments. Root growth of herbaceous and woody plants was measured in three substrates: peat:perlite (control), peat:pine-wood chips, or peat:shredded pine wood. Root growth equaled or exceeded that observed in the control substrate for species grown in pine-wood chips or shredded pine wood-amended substrates.
