• Wasps are disappearing this summer, and scientists are worried

  Britain’s wasps have become mysteriously scarce this summer, and scientists suspect an unusual combination of temperature swings, heatwaves, and food shortages may be responsible. Even the wasps that remain appear unusually small, potentially offering a glimpse of how extreme heat could reshape insect populations.

• UNESCO warns there’s close to a 100% chance of a Mediterranean tsunami

  The Mediterranean may seem far removed from the world’s major tsunami zones, but history and modern modeling show that destructive waves can strike the French Riviera with surprisingly little warning. Some tsunamis could reach shore in under 10 minutes, while past events have produced waves around two meters high, powerful currents, damage, and deaths.

• Archaeologists find a 3,000-year-old Egyptian tomb before it’s too late

  While clearing debris to protect ancient Egyptian tombs from flash floods, researchers near Luxor stumbled upon an unknown 3,000-year-old tomb. Its remarkably preserved paintings depict an official named Paser, his wife, religious scenes, and offerings of food and flowers. The discovery comes as climate-driven flooding poses a growing threat to these fragile remains.

• DNA solves the mystery of a body found in the Arctic in 1859

  Scientists have used DNA from living descendants to identify four more members of the doomed Franklin expedition, including Harry Peglar, whose identity had remained uncertain for 166 years. The findings offer new clues about the sailors who survived for years in the Arctic before joining the expedition’s ultimately fatal escape attempt.

• Scientists capture two DNA strands zipping together for the first time

  Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching DNA helices align groove for groove like a molecular zipper. The discovery confirms a theory proposed two decades ago and could help researchers understand DNA interactions involved in cancer and other cellular processes.
