First global map suggests climate change will have greatest impact on the populations least responsible for causing the problemResearchers already study how various species of plants and animals migrate in response to climate change. Now, Jason Samson, a PhD candidate in McGill University's Department of Natural Resource Sciences, has taken ...

Researchers already study how various species of plants and animals migrate in response to climate change. Now, a researcher has taken the innovative step of using the same analytic tools to measure the impact of climate change on human populations. They found that if populations continue to increase at the ...

New research examines the anxious brain during a fear conditioning task and provides insight into why some individuals may be more or less prone to anxiety disorders. The study reveals neural mechanisms that may contribute to resilience against pathological fear and anxiety. The findings may help to direct therapeutic strategies ...

New research examines the anxious brain during a fear conditioning task and provides insight into why some individuals may be more or less prone to anxiety disorders. The study, published by Cell Press in the February 10 issue of the journal Neuron, reveals neural mechanisms that may contribute to resilience ...

Throughout their lives, Native Hawaiians have higher risks of death than white Americans, according to a new study. The research is the first known study to assess mortality patterns among Native Hawaiians at the national level, including those living outside the state of Hawaii.

Researchers have recently developed and tested a technique exploiting imperfections in quantum cryptography systems to implement an attack.

International collaboration tackles the problemThe Norwegian University of Science and Technology (NTNU) and the University of Erlangen-Nürnberg together with the Max Planck Institute for the Science of Light in Erlangen have recently developed and tested a technique exploiting imperfections in quantum cryptography systems to implement an attack.Countermeasures were also implemented ...

There is a great deal of interest in factors that contribute to the vulnerability to developing post-traumatic stress disorder, or PTSD. One factor that appears to contribute to the heritable vulnerability to PTSD is a variation in the gene that codes for the serotonin transporter, also known as the serotonin ...

The cause of tuberculosis is Mycobacterium tuberculosis (Mtb), a slow-growing aerobic bacterium that divides every 16 to 20 hours. Scientists know that carbon metabolism plays a significant role in the ability of Mtb to replicate and persist in the body and that fatty acids are the major source of carbon ...

Normal individuals who scored high on a measure of impulsive/antisocial traits display a hypersensitive brain reward system, according to a brain imaging study by researchers at Vanderbilt University.

A new study has concluded that Amazon rain forests were remarkably unaffected in the face of once-in-a-century drought in 2005, neither dying nor thriving, contrary to a previously published report and claims by the Intergovernmental Panel on Climate Change.
