But keeping them in the same place throughout life is not feasible. This is because beetles are holometabolic insects that undergo a complete physical reorganization (metamorphosis) as pupae. …
The Universe is truly full of wonders, and the James Webb Space Telescope has just given us our best views of one of them.

The predicted sea rise of 27 cm is more than twice what scientists had previously expected from the melting Greenland ice sheet. Greenland’s fast-melting ice sheet will cause massive sea-level rise this century with potentially dire consequences if temperatures continue to rise, according to a study published Monday. Melting “zombie” ice cream from the huge …

Dolphins form decades of social bonds, working together between and between cliques, to help each other find mates and fend off competitors, new research has shown — behaviors not previously confirmed in animals. “These dolphins have long-term stable alliances and they have alliances between groups. Alliances of alliances of alliances, really,” said Dr Richard Connor, …
