A group of international scientists have developed a new method to study Ebola virus in wildlife. The Wildlife Conservation Society-led research describes the use of fecal samples from wild great apes to identify populations likely to have been exposed to the virus.

Researchers report the discovery of a novel mechanism in the brain involved in the formation of memory and learning. The discovery could have therapeutic ramifications for conditions including dementia, age-related memory loss or even post-traumatic stress disorder.
Scientists have discovered that knocking out the gene NrCAM leads to an increase of dendritic spines on excitatory pyramidal cells in the brains of mammals. Other studies have confirmed that the overabundance of dendritic spines on this type of brain cell allows for too many synaptic connections to form between neurons — a phenomenon strongly linked to autism.
Confidence is a familiar feeling for all of us. But scientists have found that confidence is more than an emotion. It is a measureable quantity, an objective prediction that informs our decisions. In fact, the researchers have pinpointed a brain region in rats whose function is required to for the animals to express confidence in their decisions.
British scientists say a former nurse has become the first person in the country to receive an experimental Ebola vaccine in an early trial to test its safety. The vaccine is meant to spark the immune system's production of Ebola antibodies. It does not contain any infectious material and shouldn't trigger an Ebola infection, researchers said.
The most common type of hospital-associated infection may be preventable with a vaccine, new research in mice suggests. The experimental vaccine prevented urinary tract infections associated with catheters, the tubes used in hospitals and other care facilities to drain urine from a patient’s bladder.
Neuroscientists have discovered the “molecular brakes” that time the generation of important cells in the inner ear cochleas of mice. These “hair cells” translate sound waves into electrical signals that are carried to the brain and are interpreted as sounds. If the arrangement of the cells is disordered, hearing is impaired.
Mutations in the human retinoblastoma protein gene are a leading cause of eye cancer. Now, scientists have turned to fruit fly eyes to unlock the secrets of this important cancer gene.
Artificial sweeteners, promoted as aids to weight loss and diabetes prevention, could actually hasten the development of glucose intolerance and metabolic disease; and they do it in a surprising way: by changing the composition and function of the gut microbiota — the substantial population of bacteria residing in our intestines.
Aging of insulin-secreting cells is coupled to a progressive decline in signal transduction and insulin release, according to a recent study. The finding provides a new molecular mechanism underlying age-related impairment of insulin-producing cells and diabetes.
The latest collection of CASIS-sponsored research, termed Advancing Research Knowledge (ARK)-2, centers heavily on life sciences. Investigations destined for the space station’s national laboratory include the Bone Densitometer, which will be the first X-ray machine installed on the space station. A joint project between CASIS, NASA and Techshot, the facility will be instrumental in conducting rodent research on station.
Researchers have shown that the human version of a gene called Foxp2 makes it easier to transform new experiences into routine procedures. When they engineered mice to express humanized Foxp2, the mice learned to run a maze much more quickly than normal mice.
Nanotechnology researchers have successfully engineered synthetic materials which encouraged bone formation in sheep. The advancement means the successful use of synthetic materials in bone grafts for human patients is a step closer. The material could also have potential future applications in fracture repair and reconstructive surgery.
Researchers have made a recent breakthrough with the development of a new compound found to be highly effective in animal models of spinal muscular atrophy, a neurodegenerative disease that causes muscles to weaken over time.
Thoughts of the family tree may not be uppermost in the mind of a person suffering from a slipped disc, but those spinal discs provide a window into our evolutionary past.
A team set out to better understand the molecular pathways involved in heart failure. The researchers discovered a group of long non-coding RNAs specific to heart muscle. These particular RNA pieces came from a genetic region that normally codes for myosin heavy chain proteins, which are abundant in heart tissue. Thus, the team named them Myheart.
