Suppressing emotions appears to reduce negative memories

By peering at the brains of study subjects prompted to suppress negative emotions, scientists have gained new insights into how emotional regulation influences negative feelings and memories. The researchers hope the findings will lead to new methods to combat depression.

Researchers identify B immune cells that promote axon myelination in developing neurons

Neurons are specialized cells of the nervous system that communicate using electrical signals, which propagate down long, wire-like projections called axons. The conduction of these signals requires myelin, a fatty substance that surrounds axons in much the same way that plastic coating surrounds an electrical wire.

Study highlights significant clinical differences between men and women with sleep apnea

Researchers from the UCLA School of Nursing examined clinical records and magnetic resonance imaging brain scans of patients who were recently diagnosed with sleep apnea, and discovered several apparent connections between thinning of the brain's cerebral cortex and apnea symptoms.

Researchers create cardiomyocyte molds to mend broken hearts

2.5 billion. That's approximately the number of times the human heart beats in 70 years. And sometimes during the course of its unrelenting contractions and relaxations, the heart muscle can no longer bear the strain.

Study: Soy-fed infants have differences in reproductive system tissues

Infants who consumed soy-based formula as newborns had differences in some reproductive-system cells and tissues, compared to those who used cow-milk formula or were breastfed, according to a new study.

Extracellular vesicles may serve as drug delivery vehicles for cancer treatment

Creating enough nanovesicles to inexpensively serve as a drug delivery system may be as simple as putting the cells through a sieve, according to an international team of researchers who used mouse autologous -- their own -- immune cells to create large amounts of fillable nanovesicles to deliver drugs to tumors in mice.

Streamlined workflow could pave way for simple blood test to study cancer heterogeneity in liquid biopsy

Scientists reported the development of a robust and streamlined procedure for whole-genome copy number profiling of circulating tumor cells from a simple blood test.

Study identifies two new biomarkers for common form of childhood cancer

Two new biomarkers for a type of cancer in children called neuroblastoma have been identified in a study published in the journal Cancer Cell. The findings are expected to have immediate significance for disease prognosis, and eventually also for treatment.

International research consortium identifies 22 new genetic risk factors for stroke

An international research consortium studying 520,000 individuals from around the world has identified 22 new genetic risk factors for stroke, thus tripling the number of gene regions known to affect stroke risk.

Study identifies gene that influences risk of obesity in adulthood

The importance of good nutrition in the early development of children has been recognized for many decades. Nutritional experiences in early life can have profound and long-lasting effects on body weight in later life.

Researchers develop new method to increase life span of donated brain tissue samples

Researchers at Lund University in Sweden have developed a method that enables them to use donated brain tissue from people with epilepsy for 48 hours. Previously, the researchers only had 12 hours to test new treatments before the structure of the cells started to break down. The research has now been published in the journal Scientific Reports.

New study finds that thirdhand smoke increases lung cancer risk in mice

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) identified thirdhand smoke, the toxic residues that linger on indoor surfaces and in dust long after a cigarette has been extinguished, as a health hazard nearly 10 years ago.
