This specimen of Tokummia katalepsis shows a number of strong legs on the left partially protruding from the body, the shape of the bivalved carapace and dozens of small paddle-like limbs below the trunk at the lower right. This...
This artistic conception summarizes one main finding from the present paper. Although all bioluminescent fungi emit green light (the true mushroom is the green one), the fungal luciferase can use different substrates leading to changes in intensity and color...
Scientists have identified genes that enable rainbow trout to use Earth’s magnetic field to find their way back to the streams where they were born.
