The viral hemorrhagic fevers (VHFs) are a diverse group of animal and human illnesses that are caused by four distinct families of RNA viruses: the families Arenaviridae, Filoviridae, Bunyaviridae, and Flaviviridae. All types of VHF are characterized by fever and bleeding disorders and all can progress to high fever, shock and death in many cases. Some of the VHF agents cause relatively mild illnesses, such as the Scandinavian nephropathia epidemica, while others, such as the African Ebola virus, can cause severe, life-threatening disease.

Study shows cultural images may hinder proficiency in second language skills
(Medical Xpress)—A team of combined researchers from Columbia Business School and Singapore Management University has found that people who have learned a second language become less proficient at speaking ...
Inside each of us is our own internal timing device. It drives everything from sleep cycles to metabolism, but the inner-workings of this so-called "circadian clock" are complex, and the molecular processes behind it have ...
The discerning fruit fly: Linking brain-cell activity and behavior in smell recognition
Behind the common expression "you can't compare apples to oranges" lies a fundamental question of neuroscience: How does the brain recognize that apples and oranges are different? A group of neuroscientists ...
Recent research has shown that cancer cells have a much different – and more complex – metabolism than normal cells. Now, scientists at The University of Texas at Dallas have found that exploiting these differences might ...
Researchers have discovered and mapped the signaling network between two previously unconnected proteins, exposing a link that, if broken, could cut off cancer cell growth at its starting point.
