Researchers unlock craniopharyngioma growth mechanism and identify potential new therapy

Craniopharyngiomas, a type of brain tumor, can hijack hypothalamic neurons to enhance growth. Researchers identified a promising treatment option: amlodipine besylate, a calcium channel blocker commonly used for hypertension. The medication disrupts chemical synaptic transmission between neurons and tumor cells.

Journal of Dental Research publishes study exploring the impact of early childhood exposure to fluoride on cognitive neurodevelopment

A recent study published in Journal of Dental Research examined the relationship between early childhood fluoride exposure and cognitive development. The research found that there were no significant effects of fluoride exposure on cognitive neurodevelopment, with the hypothesis of non-inferiority tests also supporting this conclusion.

Diarrheal diseases remain a leading killer for children under 5, adults 70+

A new study reports a 60% decline in global diarrheal disease mortality, but highlights regional disparities and areas for improvement, particularly in sub-Saharan Africa and South Asia. The largest decrease was among children under 5 years old, with a 79% drop in deaths, while adults 70+ still face high mortality rates.

A ‘remelting’ of lunar surface adds a wrinkle to mystery of Moon’s true age

Scientists suggest the Moon underwent a 'remelting' event due to tidal forces, resetting its geological clock and masking its true age with volcanic activity. This hypothesis could account for discrepancies in lunar-rock ages and impact basins, placing the Moon's formation between 4.43 and 4.53 billion years ago.

Miracle, or marginal gain?

A study by MIT economists suggests that industrial policy has a relatively limited impact on GDP growth, with average long-run gains of 1.08% in favorable circumstances. The research indicates that local consumer demand can curb the impact of industrial policy, putting a ceiling on directed growth.
