Proteins in one of the world's main biodiesel plants have been mapped, and it does not look good

Posted: 25 Oct 2013 08:39 AM PDT

The castor oil plant (Ricinus communis) produces beans with a high content of fatty acids from which oil is refined into biodiesel in several countries, eg. Brazil. Now scientists have succeeded in mapping proteins of the castor bean. This information might make it possible to get even more out of the bean than today. The researcher's work, however, shows that it may not be an easy task.

Physicists observe the formation of a many-body system in experiment

Posted: 25 Oct 2013 06:18 AM PDT

How large does a group of particles have to be to render moot its exact number of particles? In experiments using ultracold atoms, physicists succeeded in observing the transition to a many-body system well described by an infinite number of particles. In philosophy, this problem is known as the sorites paradox. The essential question is when a collection of elements forms a "heap."

Fish population recovery in marine reserve

Posted: 25 Oct 2013 06:18 AM PDT

Protection in the Medes Islands marine reserve started more than 25 years ago. Dusky grouper, zebra seabream and European seabass have practically reached their carrying capacity, whereas brown meagre is still approaching population stabilization and common dentex is still increasing. One exception to these trends is gilthead seabream, which decreased probably due to fishing just outside the borders of the reserve.

The researchers hope to gain new insights that will be of relevance to the development of quantum computers.

Scientists develop new method to help global coasts adapt to sea-level rise

Posted: 25 Oct 2013 06:18 AM PDT

Scientists have developed a new method to help the world's coasts adapt to global sea-level rises over the next 100 years. Future sea-level rise seems inevitable, although the rates and geographical patterns of change remain uncertain. Given the large and growing populations and economic activity in coastal zones, as well as the importance of coastal ecosystems, the potential impacts of sea-level change are far-reaching. Current methods to assess the potential impact of sea-level rise have varied significantly and hindered the development of useful scenarios and in turn, suitable adaption policies and planning. A new study has combined the available data on a number of different climate and non-climate (such as uplift, subsidence and natural phenomena - earthquakes for example) mechanisms, which contribute to sea-level change, to create appropriate scenarios of sea-level rise at any location when policy-makers consider impacts and adaption.
