Results show that the lagoons are in the process of regressing, largely due to the extraction of underground water for the Matalascaņas tourist resort (Huelva). Moreover, the natural effects of the ecosystem itself are further aggravating the situation. http://www.physorg.com/news174139526.html Space & Earth Wed, 07 Oct 2009 13:40:03 EST news174139526 Individuals who follow the Mediterranean dietary pattern -- rich in vegetables, fruits, nuts, whole grains and fish -- appear less likely to develop depression, according to a report in the October issue of Archives of General Psychiatry. http://www.physorg.com/news173987723.html Medicine & Health Mon, 05 Oct 2009 19:10:01 EST news173987723 A pioneering project to make our green vegetables even better for us has been launched by scientists at The University of Nottingham.

But sometimes, when the rains come and patches of green begin to dot dry landscapes, their populations skyrocket and something extraordinary can happen. Hormonal changes, triggered by crowding, can cause the insects to change color, become more active and congregate in huge swarms capable of decimating crops. http://www.physorg.com/news172946653.html Space & Earth Wed, 23 Sep 2009 18:10:01 EST news172946653 In a new report, University of Illinois professor Barbara H.

To measure NO3-N concentration in plant tissue, many laboratories use ion selective electrodes (ISEs). Relatively inexpensive and portable ISE nutrient monitoring devices, including the Cardy NO3-N meter, are widely used to measure fresh plant sap NO3-N levels. Although conventional means of measuring plant tissue NO3-N are accurate and reliable, they often require sophisticated equipment and trained technicians and can be time-consuming, expensive, and impractical outside of a laboratory setting. http://www.physorg.com/news171633837.html Biology Tue, 08 Sep 2009 13:20:02 EST news171633837 The price of fresh food in shops and supermarkets could be reduced if innovative work at The University of Manchester to develop intelligent low-cost sensors is successful. http://www.physorg.com/news171548748.html Chemistry Mon, 07 Sep 2009 13:50:01 EST news171548748 The emerging trend toward healthier, fresher foods that are also gentle on the environment presents new dilemmas for conscientious consumers. Marketers tout the attributes of "organic" food, while the "local foods movement" is gaining popularity throughout the world. The "organic-or-local" debate is particularly interesting when it comes to fruits and vegetables; proponents of each system offer strong evidence to support their cause. http://www.physorg.com/news171276827.html Other Sciences Fri, 04 Sep 2009 16:00:01 EST news171276827 A team of scientists has analyzed 29 esparto fields from Guadalajara to Murcia and has concluded that perennial vegetation cover is an efficient early warning system against desertification in these ecosystems.
