'Apples-to-apples' analysis of Arab development yields fresh view

The study divides Arab countries into three categories and compares their population-weighted averages in health, educational attainment, and income with those of non-Arab nations. While Arab countries have made significant progress in areas such as life expectancy and education, they lag behind in democracy and women's labor-force par...

Penn State College of Medicine research isolates liver cancer stem cells prior to tumor formation

Researchers at Penn State College of Medicine have identified a population of cancer stem cells in the liver prior to tumor formation. These malignant stem cells have been found to be resistant to chemotherapy and are thought to play a key role in driving liver cancer formation. The study suggests that targeting these cells could poten...

Scientists cure color blindness in monkeys

Researchers from the University of Florida and the University of Washington successfully used gene therapy to restore color vision in two squirrel monkeys. The study demonstrates the potential for this treatment to target adult vision disorders involving cone cells, a crucial step towards developing therapies for human cone diseases.

Melting of the Greenland ice sheet mapped

Researchers have analyzed ice cores from Greenland and small ice caps to show the evolution of the ice sheet over 11,700 years. The findings reveal that changes in elevation cause different temperatures, allowing scientists to use small ice caps as a standard reference for climate history.

Intermittent preventive malaria treatment for African infants is safe and effective, but more long-acting drugs desperately needed

A recent study found that intermittent preventive malaria treatment in African infants is both safe and effective, with sulfadoxine-pyrimethamine providing protection for up to 6 weeks. However, the use of this drug is limited by potential resistance and its risks. New long-acting antimalarial drugs are urgently needed for this strategy.

Canadian scientists uncover a new mechanism regulating fetal growth and neonatal survival

Researchers have identified a critical role for protein kinase Erk3 in fetal growth potential and lung maturation, revealing the loss of this function leads to fetal growth restriction and early neonatal lethality. This finding provides new insights into intrauterine growth restriction and its associated risks.

GPs' gut feelings defined

Researchers define 'gut feelings' experienced by GPs as two types: sense of alarm and reassurance. The former involves feeling uneasy about possible adverse outcomes, while the latter means feeling secure despite uncertainty. This definition aims to facilitate future research on the effectiveness of 'gut-compass'.
