Utilizing messages focused on images created by local artists and written information communicated through local dialects proved essential to counter misperceptions during the Ebola epidemic in Sierra Leone, according to a study conducted in part by Muriel J. Harris, Ph.D., associate professor, University of Louisville School of Public Health and Information Sciences, Department of Health Promotion and Behavior Sciences.

Don't let their appearance fool you: Thimble-sized, dappled in cheerful colors and squishy, poison frogs in fact harbor some of the most potent neurotoxins we know. With a new paper published in the journal Science, scientists are a step closer to resolving a related head-scratcher -- how do these frogs keep from poisoning themselves? And the answer has potential consequences for the fight against pain and addiction.

How did Neanderthals grow? Does modern man develop in the same way as Homo neanderthalensis did? How does the size of the brain affect the development of the body? A study led by the Spanish National Research Council (CSIC) researcher, Antonio Rosas, has studied the fossil remains of a Neanderthal child's skeleton in order to establish whether there are differences between the growth of Neanderthals and that of sapiens.

Exceptionally preserved trilobite fossils from China, dating back to more than 500 million years ago, have revealed new insights into the extinct marine animal's digestive system. Published today in the journal PLOS ONE, the new study shows that at least two trilobite species evolved a stomach structure 20 million years earlier than previously thought.

Chronic tissue inflammation resulting from obesity is an underlying cause of insulin resistance and type 2 diabetes. But the mechanism by which this occurs has remained cloaked, until now.

In a paper, published in the journal Cell on September 21, University of California San Diego School of Medicine researchers identified exosomes -- extremely small vesicles or sacs secreted from most cell types -- as the missing link.

Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study published this week in the journal Landscape Ecology.

The study examines grasslands called dolomite glades in the Mark Twain National Forest near Ava, Missouri. It analyzed historical aerial photos and found that woody vegetation cover increased from 8 percent in 1939 to 59 percent in 2014.

WASHINGTON -- A new imaging technique makes it possible to precisely digitize clear objects and their surroundings, an achievement that has eluded current state-of-the-art 3D rendering methods. The ability to create detailed, 3D digital versions of real-world objects and scenes can be useful for movie production, creating virtual reality experiences, improving design or quality assurance in the production of clear products and even for preserving rare or culturally significant objects.

DETROIT - A novel psychological therapy that encourages addressing emotional experiences related to trauma, conflict and relationship problems has been found helpful for people with the chronic pain condition fibromyalgia. A research team led by Mark A. Lumley, Ph.D., distinguished professor of psychology in the College of Liberal Arts and Sciences at Wayne State University, in collaboration with a team from the University of Michigan Medical Center led by David A. Williams, Ph.D., professor of anesthesiology, has released the results of its research in the prestigious journal, PAIN.

The first large-scale study of ancient human DNA from sub-Saharan Africa opens a long-awaited window into the identity of prehistoric populations in the region and how they moved around and replaced one another over the past 8,000 years.

Cold Spring Harbor, NY - In a major step forward in research, scientists at Cold Spring Harbor Laboratory (CSHL) today publish in Cell a discovery about the molecular-genetic basis of neuronal cell types. Neurons are the basic building blocks that wire up brain circuits supporting mental activities and behavior.
