Arctic refreezing experiments and ancient solstice monuments dominate this week's space and astronomy news, alongside major discoveries in climate science and coral reef protection.

Scientists are exploring ambitious plans to refreeze Arctic sea ice as climate change accelerates melting, with researchers visiting field sites to test whether drastic geoengineering measures could help restore polar ice that is visibly disappearing.

Archaeologists have discovered a 5,000-year-old solstice-aligned monument near Stonehenge in Wiltshire that may represent a prototype for the famous stone circle, marking a 'once in a lifetime find' according to Wessex Archaeology.

Research identifies specific ocean areas where coral reefs are surprisingly resilient, with cooler currents and favorable conditions providing natural protection against global warming's worst effects on marine ecosystems.

The 'Earth's Black Box' monument is being installed in remote Tasmania to permanently record humanity's climate data and actions, creating a historical archive of the climate crisis for future generations.

New study reveals HPV vaccines administered in early adolescence reduce the risk of cervical cancer death before age 30 to almost zero, though experts warn vaccination rate declines could reverse this progress.

Researchers debate whether climate change is intensifying El Niño phenomena, as a potentially record-breaking El Niño event begins and scientists examine the connection between global warming and the weather system's severity.

The Biodiversity Heritage Library, an invaluable digital archive containing 64 million pages of historic scientific texts from world museums and universities, faces an uncertain future despite its critical role in species research.

Cambridge University experts have recreated a 336-year-old garden to honor John Ray, the 17th-century botanist who coined the terms 'petal' and 'pollen' and helped establish foundations for natural history study.

Farmers in England are using AI-powered prediction maps to reduce pesticide use by up to 50 percent, with the Defra-funded Slimers project helping develop tools that identify optimal timing for slug control measures.
