Astronomers measure the elusive extragalactic background light

Tweet

RIVERSIDE, Calif. — If all the light emitted by all galaxies in the observable universe at all wavelengths during all of cosmic history were known, it would clue astronomers about the entire history of galaxy formation and evolution, and provide insights to key aspects of the expansion history of the universe.

Researchers identify first drug targets in childhood genetic tumor disorder

Tweet

Two mutations central to the development of infantile myofibromatosis (IM)—a disorder characterized by multiple tumors involving the skin, bone, and soft tissue—may provide new therapeutic targets, according to researchers from the Icahn School of Medicine at Mount Sinai. The findings, published in the American Journal of Human Genetics, may lead to new treatment options for this debilitating disease, for which the only current treatment option is repeated surgical removal of the tumors.

Facial-recognition technology proves its mettle

Tweet

In a study that evaluated some of the latest in automatic facial recognition technology, researchers at Michigan State University were able to quickly identify one of the Boston Marathon bombing suspects from law enforcement video, an experiment that demonstrated the value of such technology.

In the Pattern Recognition and Image Processing laboratory, Anil Jain, MSU Distinguished Professor of computer science and engineering, and Josh Klontz, a research scientist, tested three different facial-recognition systems.

Malnutrition exacerbates Giardia infection in mice

Tweet

Giardia is a common parasite that frequently infects young children in the developing world. It is commonly encountered through contaminated food, soil, or water.

The parasite lives inside the intestines and can cause severe diarrhea and other gastrointestinal problems and Giardia infection has been associated with developmental growth delays. Because the majority of infected individuals do not experience symptoms and frequently are infected with other pathogens, it is unclear if endemic Giardia directly stunts growth.

Hormone levels may provide key to understanding psychological disorders in women

Tweet

Women at a particular stage in their monthly menstrual cycle may be more vulnerable to some of the psychological side-effects associated with stressful experiences, according to a study from UCL.

The results suggest a monthly window of opportunity that could potentially be targeted in efforts to prevent common mental health problems developing in women. The research is the first to show a potential link between psychological vulnerability and the timing of a biological cycle, in this case ovulation.
