Researchers have discovered how toxoplasma gondii, a single-celled parasite, maintains a steady supply of nutrients while replicating inside of its host cell: it calls for delivery.
Biological evolution inspires machine learning
Posted June 18, 2019
Evolution allows life to explore almost limitless diversity and complexity. Scientists hope to recreate such open-endedness in the laboratory or in computer simulations, but even sophisticated computational techniques like machine learning and artificial intelligence can't provide the open-ended tinkering associated with evolution. Here, common barriers to open-endedness in computation and biology were compared, to see how the two realms might inform each other, and ultimately enable machine learning to design and create open-ended evolvable systems.
The benefits of being different

Six different color morphs of the elusive Asiatic golden cat have been discovered in Northeast India -- with the findings being hailed as 'an evolutionary puzzle' -- as the world's greatest number of different colored wild cat species in one area are reported.
