Tailoring treatment of patients with the lung disease COPD

The study found that patients with low risk of exacerbations do not benefit from low to moderate dose inhaled corticosteroids, while high doses are associated with severe side effects. Tailoring treatment according to patient characteristics, such as age and blood cell count, can minimize over- and underuse of inhaled corticosteroids.

Why do short-lived lung infections lead to long-lasting lung damage?

A study published in the Journal of Clinical Investigation found that infection triggers the expression of a protein called IL-33, leading to overgrowth of air spaces and increased mucus production. The researchers suggest that blocking this process could prevent chronic lung damage caused by viral infections.

Central European prehistory was highly dynamic

A new study identifies at least three migratory events that shaped central European prehistory, revealing a more dynamic period than previously thought. Genetic profiles show evidence of recent migrations and novel insights into social processes, such as the expansion of Corded Ware culture and the assimilation of women.

Pictograms are first written accounts of earthquakes in pre-Hispanic Mexico

Researchers have discovered pictograms depicting earthquakes in the Codex Telleriano-Remensis, a 16th-century Mexican codex. The pictograms provide early written evidence of earthquakes in pre-Hispanic times, extending the region's seismic history back to the 15th century.

New class of habitable exoplanets represent a big step forward in the search for life

Astronomers have identified a new class of habitable exoplanets dubbed 'Hycean' which are hot and ocean-covered with hydrogen-rich atmospheres, potentially supporting microbial life. These planets offer a wider habitable zone than Earth-like planets, making them promising candidates for finding biosignatures of life.

Largest real-world study of COVID-19 vaccine safety published by Israel's Clalit Research Institute in The New England Journal of Medicine

A large-scale analysis of Israel's COVID-19 vaccination data found that the Pfizer/BioNTech BNT162B2 vaccine is very safe, with only a few potential side effects. The study also revealed that coronavirus infection poses a much higher risk of serious adverse events compared to vaccination.
