Hot news flash! Menopause, sleepless nights make women's bodies age faster

Menopause--and the insomnia that often accompanies it --make women age faster, two new studies reveal. The work suggests these factors could increase women's risk for aging-related diseases and earlier death.

Process could make key biodegradable polymer stronger and longer-lasting

The creation of a new polymer morphology in a material called PLA could lead to better medical implants and drug-delivery devices.

New gene variants present in three percent of all ALS patients

Variations in a gene with multiple functions in neurons are present in approximately 3 percent of all cases of ALS in North American and European populations, both sporadic and familial, making it one of the most common genetic causes of the disease, according to a new article.

Embryonic gene Nanog reverses aging in adult stem cells

In a series of experiments, the embryonic stem cell gene Nanog kicked into action dormant cellular processes that are key to preventing weak bones, clogged arteries and other telltale signs of growing old.

Placenta-on-a-chip

Researchers have developed the first placenta-on-a-chip that can fully model the transport of nutrients across the placental barrier. The flash-drive-sized device contains two layers of human cells that model the interface between mother and fetus.

Among the oldest adults, poor balance may signal higher risk for dementia

In a first-of-its-kind study, researchers examined whether four different measures of poor physical performance might be linked to increased dementia risk for people aged 90 and older.

Predicting the risk for developing pneumonia in older adults

Researchers have developed a 'prediction score' to help healthcare professionals determine which older adults might be most at risk for developing pneumonia.

Bio-engineered molecule shows promise for quick control of bleeding

Hematology researchers have developed a novel genetically engineered clotting factor that can control bleeding in animal models. If the factor proves effective in humans, it may provide a quick-acting countermeasure for surgery patients and others vulnerable to serious bleeding as a result of new blood-thinning drugs.

DNA sequencing uncovers latent risk for developing cystic fibrosis

All babies with a known mutation for cystic fibrosis (CF) and second mutation called the 5T allele should receive additional screening in order to better predict the risk of developing CF later in life, new research shows.

Sub-set of stem cells found to minimize risks when used to treat damaged hearts

Scientists use mathematical modeling to simulate human mesenchymal stem cell delivery to a damaged heart and found that using one sub-set of these stem cells minimizes the risks associated with this therapy. The study represents a development in novel strategies to repair and regenerate heart muscle and could improve stem cell treatments for heart attack patients.
