- Severed sea cucumber appendages don't seem to die
Scientists discovered that severed tissue from the sea cucumber Psolus fabricii can survive indefinitely in ordinary seawater, a phenomenon described as 'naturally occurring tissue immortality.' The study, led by Sara Jobson of Memorial University of Newfoundland, highlights the species' remarkable regenerative capabilities in harsh environments.
- Arctic Ocean passed a tipping point and scientists say it may never recover
The Arctic Ocean may have crossed a dangerous tipping point due to rapid sea ice disappearance, triggering a chemical shift that reduces nitrate levels. This decline in nitrate threatens Arctic plankton, which could disrupt the entire food web, impacting fish, seabirds, whales, and polar ecosystems.
- Arctic sea ice hits a record LOW - as scientists warn we're inching closer to a 'point of no return'
Arctic sea ice has reached a record low, prompting scientists to warn of a potential point of no return. This milestone indicates a significant shift in the Earth's climate. The rapid decline of Arctic sea ice is a pressing concern for environmentalists and researchers.
