Why is Mars so different from Earth?
April 1, 2015 07:40 AM - Roger Greenway, ENN

Did Mars ever support life of any sort?  Why is Mars so different from Earth? Can we deduce its history from current conditions?

NASA's Curiosity rover is using a new experiment to better understand the history of the Martian atmosphere by analyzing xenon. 

While NASA's Curiosity rover concluded its detailed examination of the rock layers of the "Pahrump Hills" in Gale Crater on Mars this winter, some members of the rover team were busy analyzing the Martian atmosphere for xenon, a heavy noble gas. 

Curiosity's Sample Analysis at Mars (SAM) experiment analyzed xenon in the planet's atmosphere. Since noble gases are chemically inert and do not react with other substances in the air or on the ground, they are excellent tracers of the history of the atmosphere. Xenon is present in the Martian atmosphere at a challengingly low quantity and can be directly measured only with on-site experiments such as SAM.

Antioxidant Effects differ by Leaf Color
March 27, 2015 01:47 PM - University of the Basque Country

Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. According to a study led by the researcher Usue Pérez-López of the Department of Plant Biology and Ecology of the UPV/EHU's Faculty of Science and Technology, the colour of the leaves of these vegetables determines the speed at which their compounds act. So lettuces with green leaves have antioxidants that react more slowly while red-leaf ones have a faster effect. The results of this study have been set out in a paper "Phenolic Composition and Related Antioxidant Properties in Differently Coloured Lettuces: A Study by Electron Paramagnetic Resonance (EPR) Kinetics" recently published by the ‘Journal of Agricultural and Food Chemistry'.

The highlight of the "Green Knesset" Project: The unveiling of the largest solar field in any parliament in the world

Editor, ENN

In the past few weeks, giant cranes have unloaded some 1,500 solar panels onto the Knesset's (the Israeli parliament) roofs. These panels were created especially for the Knesset's solar field, which is laid out over 4,650 square meters of the Knesset roofs and will have an installed capacity of 450 kilowatts. The solar array, which cost the Knesset NIS 2.4 million, will create some 10% of the Knesset's electricity, and together with additional energy-saving measures, it will help reduce the Knesset's energy use by a third.

The solar array is expected to save the Knesset NIS 300,000 every year. It will operate according to the net-metering method, under which electric energy generated by an electric consumer from an eligible on-site generating facility and delivered to the local distribution facilities may be used to offset electric energy provided by the electric utility to the electric consumer during the applicable billing period. The Knesset's solar array will be the first of any national institution to operate according to this method. Director General of the Knesset, Mr. Ronen Plot, hopes that other government institutions and local authorities will follow suit and establish solar fields of their own.
