Toxin-adapted fish pass down epigenetic mutations to freshwater offspring
PULLMAN, Wash. – You can take a fish out of toxic water, but its epigenetic mutations will remain for at least two generations. A research team led by Washington State University scientists analyzed the epigenetics–molecular factors and processes that determine…
The survivability of animal species depends on the number of offspring
Researchers from Tel Aviv University took part in a new international study proposing an amendment to the widely accepted theory on the extinction of animal species – by moving the focus from the animal’s body size to its reproductive capacity.

If trend of declining coral growth continues at the current rate, the world’s coral reefs may cease calcifying around 2054
New dipping solution turns the whole fish into valuable food
When herring are filleted, more than half their weight becomes a low-value ‘side stream’ that never reaches our plates – despite being rich in protein and healthy omega-3 fatty acids. Now, scientists from Chalmers University of Technology, Sweden, have developed…
