Washington, August 13: A new research by scientists, through analysis of topography, ice, and free atmospheric change, has found that the melting of ice on mountains speed up their temperature rise.

The research was conducted by N. C. Pepin from the University of Portsmouth, U. K., and

J. D. Lundquist from University of Washington, US.

Forecasting how mountains will respond to climate change requires not only model estimations of large-scale regional warming trends, but also estimates of if and how warming rates vary with elevation.

Washington, August 13: University of Nottingham scientists have for the first time artificially reproduced a common form of dementia, a "crucial breakthrough" that may help advance the understanding of the disease.

The researchers say that their work has provided them with the first ever opportunity to map the onset of the disease, similar to Alzheimer's, and track how drugs affect it.

They hope that their research will enable them to develop treatments to halt the onset of the disease.

Writing about their study, the researchers revealed that described dementia with Lewy bodies as the second most ost common form of dementia.

Washington, Aug 13 (ANI): Watching an action star walk along the ledge of a skyscraper makes us skip a heartbeat, as if we were risking our own life. Also, while reading a book that describes the same scene can give goosebumps. Now, a team of researchers has come up with an answer to explain why exactly this happens.

At the NeuroImaging Center of the University Medical Center Groningen of the University of Groningen (the Netherlands), Mbemba Jabbi, Jojanneke Bastiaansen and Christian Keysers compared what happens in our brains when we view the facial expressions of other people with the brain activity as we read about emotional experiences.

Washington  - The US government has spent 85 billion dollars paying contractors for work in Iraq since the war began more than five years ago, according to a report released Tuesday by the Congressional Budget Office.

Washington  - The US government on Tuesday placed sanctions on an additional five Iranian entities accused of supporting the Islamic state's nuclear and missile activities.

The US Treasury Department said the entities served as front organizations to assist in the country's development of nuclear technology and ballistic missiles.

"These five nuclear and missile entities have been used by Iran to hide its illicit conduct and further its dangerous nuclear ambitions," said Stuart Levey, the Treasury Department's undersecretary for terrorism and financial intelligence.
