Ultrahot exoplanet, atmospheric differences: Researchers discovered clear differences in the atmosphere between the morning and evening sides of the ultrahot gas planet WASP-121 b using the James Webb Space Telescope (JWST).

Temperature and chemical variations: The evening side absorbs more infrared light due to higher temperatures caused by strong winds moving heat eastward, while water molecules decrease in the evening terminator due to high temperatures breaking them apart.

Planetary rotation and observation method: WASP-121 b’s synchronous rotation reveals different atmospheric regions during transit, allowing scientists to analyse changes in light absorption over time and longitude.

New research found that extreme heat is already influencing how people with cancer manage daily life, access care, and make treatment-related decisions. The study highlights the need to integrate environmental risk into cancer care planning, from clinical conversations and appointment planning to caregiver guidance and community support.

Researchers discover that tiny atmospheric particles can have opposite effects on Earth's climate depending on how quickly the atmosphere responds. Why it matters: Aerosols are one of the largest sources of uncertainty in climate projections. This study shows that their impact can change over time, initially warming the atmosphere before later cooling it. The findings could help scientists improve climate models and make more accurate predictions of future climate change.

Storm Dave, which swept across northern Europe over the Easter weekend, is a recent example of what new research from the University of Gothenburg has revealed. Spring storms forming over the North Atlantic have become more common than they were 80 years ago, and this is due to climate change.
