1. 5,500-year-old site in Jordan reveals a lost civilization’s secrets

   After the collapse of the Chalcolithic culture around 3500 BCE, people in Jordan’s Murayghat transformed their way of life, shifting from domestic settlements to ritual landscapes filled with dolmens, standing stones, and megalithic monuments. Archaeologists from the University of Copenhagen believe these changes reflected a creative social response to climate and societal upheaval.

2. Scientists uncover the secret triggers of ‘impossible’ earthquakes

   Once considered geologically impossible, earthquakes in stable regions like Utah and Groningen can actually occur due to long-inactive faults that slowly “heal” and strengthen over millions of years. When reactivated—often by human activities—these faults release all that built-up stress in one powerful event before stabilizing again. This discovery reshapes how scientists assess earthquake risks in areas once thought safe, offering new insights for geothermal and energy storage projects that rely on the Earth’s shallow subsurface.

3. Even climate fixes might not save coffee, chocolate, and wine, scientists warn

   Even with futuristic geoengineering methods like Stratospheric Aerosol Injection, the fate of wine, coffee, and cacao crops remains uncertain. Scientists found that while this intervention could slightly cool the planet, it cannot stabilize the erratic rainfall and humidity that devastate yields. The findings reveal that only a fraction of major growing regions might benefit, leaving most producers exposed to volatile harvests and economic instability.

4. 2.7-million-year-old tools reveal humanity’s first great innovation

   Researchers uncovered a 2.75–2.44 million-year-old site in Kenya showing that early humans maintained stone tool traditions for nearly 300,000 years despite extreme climate swings. The tools, remarkably consistent across generations, helped our ancestors adapt and survive. The discovery reshapes our understanding of how early technology anchored human evolution.

5. Plastic-eating bacteria discovered in the ocean

   Beneath the ocean’s surface, bacteria have evolved specialized enzymes that can digest PET plastic, the material used in bottles and clothes. Researchers at KAUST discovered that a unique molecular signature distinguishes enzymes capable of efficiently breaking down plastic. Found in nearly 80% of ocean samples, these PETase variants show nature’s growing adaptation to human pollution.
