Brain structure may be root of apathy

Researchers at Oxford University found that apathetic individuals showed more activity in the pre-motor cortex when making decisions, despite being less likely to accept effortful choices. This suggests that biology, not attitude, may be the root cause of apathy in some people.

Wild birds choose love over food

In a study by Oxford University researchers, wild birds chose to stay close to their partners over accessing food, even when it meant spending less time foraging. This demonstrates the importance of social relationships for wild birds and shows how individual behavior can be shaped around maintaining key relationships.

It's music to my eyes

A study published in Frontiers in Human Neuroscience found that listeners' pupils dilate in response to emotional music, reflecting both the music's content and the listener's personal connection. The research used eye trackers to measure pupil size while participants listened to short music excerpts from the Romantic era.

Miniaturizable magnetic resonance

A team of physicists at the University of Alberta has created a method to measure magnetic resonance using mechanical twisting motion detected with light, enabling the miniaturization of magnetic sensors. This technology opens up possibilities for various scientific applications in healthcare, technology, and energy.

Despite health law's bow to prevention, US public health funding is dropping: AJPH study

Researchers find per capita public health spending declining from $281 in 2008 to $256 in 2014, reflecting a $40.2 billion loss to disease prevention and related programs. This decline reflects the nation's 'dangerously out of balance' healthcare system, where more is spent treating disease than preventing it.

HIV spreads faster as violent conflict looms

A new study by Brown University found that HIV incidence rises significantly in the five years leading up to bloodshed in sub-Saharan Africa. The rate of new infections increases by 2.1 infections per 1000 people a year during this period, compared to times of peace.
