Deux super-Terres « habitables » découvertes autour d’étoiles proches

Deux super-Terres « habitables » découvertes autour d’étoiles proches

Deux exoplanètes récemment détectées par les chercheurs de la Carnegie Institution vont constituer de nouvelles cibles de choix pour la recherche de la vie.

Baptisées GJ229Ac et GJ180d, ces exoplanètes sont à la fois d’une taille proche de celle de la Terre, autrement dit probablement rocheuses, et situées dans la zone habitable de leur étoile respective, c’est-à-dire susceptibles d’abriter de…

Parques eólicos en ultramar podrían generar energía al mundo entero

Parques eólicos en ultramar podrían generar energía al mundo entero

Los parques eólicos construidos en mar abierto pueden generar mucha más energía renovable que los terrestres, posiblemente lo suficiente para alimentar al mundo entero, aseguró un estudio estadounidense el lunes. Investigadores de la Carnegie Institution for Science descubrieron que la mayor velocidad del viento sobre el océano abierto podría producir cinco veces más energía que la generada por…

Green Algae Could Hold Clues for Engineering Faster-Growing Crops

Green Algae Could Hold Clues for Engineering Faster-Growing Crops

Two new studies of green algae — the scourge of swimming pool owners and freshwater ponds — have revealed new insights into how these organisms siphon carbon dioxide from the air for use in photosynthesis, a key factor in their ability to grow so quickly. Understanding this process may someday help researchers improve the growth rate of crops such as wheat and rice.

In the studies published this…

Projected Precipitation Increases Are Bad News for Water Quality

Projected Precipitation Increases Are Bad News for Water Quality

Increased precipitation from a changing climate could pollute U.S. waterways with excess nitrogen, increasing the likelihood of severe water quality impairment from coast to coast, according to a new study by scientists Eva Sinha and Anna Michalak of the Carnegie Institution for Science and Venkatramani Balaji of Princeton University.

The results are published in this week’s issue of the journal

C O N T E N T S:

KEY TOPICS

“Vera was an amazing scientist and an amazing human being,” says Neta Bahcall, a colleague of Rubin’s from Princeton University.(More…)

If little girls growing up today someday use Rubin’s data, she’ll have left a legacy greater than all those celebrities combined.(More…)

He concludes with a monition that can be considered his legacy: “The universe is so beautiful –…

Warmer, Wetter Climate Would Impair California Grasslands

Warmer, Wetter Climate Would Impair California Grasslands

Results from one of the longest-running and most extensive experiments to examine how climate change will affect agricultural productivity show that California grasslands will become less productive if the temperature or precipitation increases substantially above average conditions from the past 40 years.

That’s one conclusion from a new study in this week’s Early Edition of the Proceedings of…

CROP ROOTS ENACT AUSTERITY MEASURES DURING DROUGHT TO BANK WATER

Monday, July 11, 2016

Stanford, CA— With a growing world population and a changing climate, understanding how agriculturally important plants respond to drought is crucial. New work from a team led by Carnegie’s José Dinneny discovers a strategy employed by grasses in drought conditions that could potentially be harnessed to…
