Deep-Sea Worms Tolerate High Arsenic
AI द्वारा रिपोर्ट किया गया
Researchers revealed on September 6, 2025, the discovery of deep-sea worms capable of tolerating high levels of arsenic, expanding knowledge of extremophile adaptations. This finding uncovers new biological mechanisms for toxin resistance. It was reported alongside other marine science updates.
Hippos lived in ice age Germany until 31,000 years ago
New research reveals that hippos survived in central Europe much longer than previously believed, persisting in Germany's Upper Rhine Graben until about 31,000 years ago. Ancient DNA and radiocarbon dating show these animals coexisted with mammoths during a milder phase of the last ice age. The findings challenge earlier timelines of hippo extinction in the region.
Study challenges narrative of accelerating extinction rates
A new analysis of 500 years of extinction data reveals that species losses peaked about a century ago and have since declined, contradicting assumptions of a rapidly worsening crisis. Researchers from the University of Arizona found that past extinctions were mainly driven by invasive species on islands, while current threats center on habitat destruction on continents. The study emphasizes the need for accurate assessments to inform conservation efforts.
Tiny worm uses static electricity to hunt flying insects
Scientists have discovered that a minuscule parasitic nematode employs static electricity to leap onto flying insects, boosting its hunting success dramatically. The research, involving high-speed imaging and mathematical models, reveals how electrostatic forces enable the worm to bridge gaps in midair. This finding highlights the role of invisible electrical interactions in small organisms' survival.
