The nation's top infectious disease official says there's hope that a vaccine against Ebola will be available as early as next July. Dr. Anthony Fauci of the National Institutes of Health says such a preventive vaccine has been successfully tested with monkeys.

Mosaicism: Study Clarifies Parents as Source of New Mutations

July 31, 2014 3:36 pm | News | Comments

Scientists have long speculated that mosaicism plays a bigger role in the transmission of rare disease mutations than is currently known. Now, a study sheds new light on the frequency of mosaicism in genomic disorders and its influence on recurrence risk.

Engineering a Protein to Prevent Brain Damage from Toxic Agents

July 31, 2014 3:21 pm | News | Comments

Research at New York University is paving the way for a breakthrough that may prevent brain damage in civilians and military troops exposed to poisonous chemicals—particularly those in pesticides and chemical weapons. The research outlines the advancement in detoxifying organophosphates, which are compounds commonly used in pesticides and warfare agents.

Strict Genomic Partitioning by Biological Clock Separates Key Metabolic Functions

July 31, 2014 3:10 pm | News | Comments

Much of the liver’s metabolic function is governed by circadian rhythms—our own body clock—and UC Irvine researchers have now found two independent mechanisms by which this occurs. The study reveals new information about the body clock’s sway over metabolism and points the way to more focused drug treatments for liver disease and such metabolic disorders as obesity and diabetes.

How Is Depression Related to Dementia?

July 31, 2014 3:05 pm | News | Comments

A new study gives insight into the relationship between depression and dementia. The current study, which involved 1,764 people from the Religious Orders Study and the Rush Memory and Aging Project, indicates that the association of depression with dementia is independent of dementia-related brain changes.
