First discovery in decades of blue whales near Seychelles
Blue whales are fascinating animals. At 24–30 meters in length (longer than a basketball court) they are the largest creatures on Earth. They are also among the rarest. Estimates suggest that there are only about 5,000 to 15,000 blue whales left in.....»»
Computer model helps support theory of asteroid Kamo"oalewa as ejecta from the moon
A small international team of planetary scientists has found evidence supporting the theory that the near-Earth asteroid Kamo'oalewa is ejecta from the moon. In their paper published in the journal Nature Astronomy, the group describes their data-dri.....»»
Mangrove blue carbon at higher risk of microplastic pollution
Earth's oceans and coastal ecosystems are a major sink for carbon storage, known as blue carbon. Sequestration of carbon is vitally important in the fight against climate change as it 'locks away' this molecule, alleviating pressure on greenhouse gas.....»»
