Diet rich in omega 3 fatty acids may help reduce headaches

A recent trial found that consuming a diet high in omega 3 fatty acids significantly reduces headache frequency and severity compared to a typical diet. The study, published in The BMJ, suggests that increasing omega 3 intake can lead to reduced levels of pain-reducing oxylipins and improved quality of life for those with migraines.

Prevalence of COVID-19 among hospitalized infants varies with levels of community transmission

A new study found that COVID-19 infection rates among infants hospitalized for potential serious bacterial infections were higher during periods of high community transmission, but lower when transmission was low. The study also found a relatively low incidence of other respiratory viruses in this age group.

Have a pandemic plan? Most people did not

A survey of 217 participants found that most people were unprepared to handle the COVID-19 pandemic, with 62% having no plan at all. The study suggests that building basic health literacy skills can help individuals make informed decisions about their health and safety.

A white dwarf living on the edge

Astronomers have identified a white dwarf so massive that it may collapse. The discovery provides an example of what can happen after the phase where two less massive white dwarfs merge into one. This process boosts the magnetic field and speeds up rotation compared to progenitors.
