Cephalopods deserve higher welfare standards in research

Ferromagnets, such as iron, cobalt, and nickel, are materials with a strong, spontaneous, and permanent magnetic field. Over 150 years ago, the physicist and mathematician James Clerk Maxwell speculated that under specific conditions, non-spinning ferromagnets or electromagnets would behave as gyroscopes, objects that maintain their orientation, typically due to the angular momentum arising from spinning.

Many scorpion species use blends of iron, zinc and manganese to enhance the toughness of their deadly weaponry

New experiments suggest that freezing and thawing on early Earth may have helped primitive cell-like structures grow and evolve. Tiny lipid bubbles behaved very differently depending on their membrane makeup—some fused into larger compartments and captured DNA more efficiently. These fusion events could have mixed key molecules, setting the stage for more complex chemistry.
