TB patients globally often incur "catastrophic costs" of up to $11,329 USD, despite many countries offering free treatment, with predominant drivers of cost being hospitalization and loss of income

Despite free treatment in many countries, TB patients incur catastrophic costs due to hospitalization and lost income. A systematic review found that these costs can be prohibitively high for individuals in low-, middle-, and high-income settings.

Blood test may rule out future dementia risk

A new study published in Nature Medicine has investigated the potential of specific biomarkers to predict dementia risk up to ten years before diagnosis. The study found that low levels of certain biomarkers may rule out future dementia, but elevated levels alone are not reliable for identification.

Existing international law can help secure peace and security in outer space, study shows

A recent study by Chris O'Meara from the University of Exeter Law School argues that existing laws can be used to limit when and how states may lawfully target satellites using ASAT technologies. This could help address pressing international concerns regarding space militarization and the fear of wars between states.

Migrating flies vital for people and nature

The study found that almost 600 of the over 125,000 known fly species are likely to be migratory, highlighting their importance as pollinators, decomposers, and pest controllers. The review emphasizes the need for connected habitats to support flies along their epic journeys, as climate change and human impacts threaten many species.

Melodies of musical ‘starquakes’ shed new light on how our galaxy formed

Astronomers have discovered that stars in a specific region of our galaxy exhibit fluctuations in brightness, caused by 'starquakes'. These fluctuations can be translated into frequencies, providing clues about a star's age and properties. The study, led by Dr Claudia Reyes, offers new insights into how our galaxy formed.
