More carbohydrates make trees more resistant to drought

How well tropical trees weather periods of drought depends on the carbohydrates stored, as revealed by a novel experiment conducted by an international team of researchers headed by ecologists from the University of Zurich in contribution to the University Research Priority Program on "Global Change and Biodiversity." The findings are extremely important for assessing the resistance of tropical forests to climate change and reforestation.

New theory on cause of ice age 2.6 million years ago

New research in the journal Nature's Scientific Reports has provided a major new theory on the cause of the ice age that covered large parts of the Northern Hemisphere 2.6 million years ago.

The study, co-authored by Dr Thomas Stevens, from the Department of Geography at Royal Holloway, University of London, found a previously unknown mechanism by which the joining of North and South America changed the salinity of the Pacific Ocean and caused major ice sheet growth across the Northern Hemisphere.

Workshop on Protection of Endangered Birds

DAMASCUS, (ST) -The Minister of State for Environmental Affairs Dr. Nazira Sarkis underlined that the government had given marsh Jabboul a great importance to the great richness in biodiversity and its importance as a world site exposed to many different threats.

Dr. Sarkis, during a workshop to protect endangered birds in the marsh Jabboul, explained that the project aims to improve the status of protection for endangered species of birds and biodiversity conservation in the marsh Jabboul through the promotion of fishing laws and spreading awareness among locals and fishermen to preserve the birds and their habitats. The workshop carried out by the Ministry of State for Environmental Affairs and the Syrian Society for the Protection of Wildlife in cooperation with the Small Grants Program (SGP).

Geologists confirm oxygen levels of ancient oceans

Geologists in the College of Arts and Sciences have discovered a new way to study oxygen levels in Earth's oldest oceans.

Zunli Lu and Xiaoli Zhou, an assistant professor and Ph.D. student, respectively, in the Department of Earth Sciences, are part of an international team of researchers whose findings have been published by the journal Geology (Geological Society of America, 2014). Their research approach may have important implications for the study of marine ecology and global warming.

Astronomers discover two new worlds orbiting ancient star next door

An international team of astronomers, including five Carnegie scientists, reports the discovery of two new planets orbiting a very old star that is near to our own Sun. One of these planets orbits the star at the right distance to allow liquid water to exist on its surface, a key ingredient to support life.
