• Undersea robot reveals 'schools' of animals in deep scattering layers

  10-07-2017 22:34
  
  Throughout the world ocean, animals congregate at certain depths, forming layers that can be hundreds of meters thick and may extend horizontally for dozens or even hundreds of kilometers. Because these dense layers of animals reflect sound waves, they are sometimes called "sound-scattering layers" or "deep scattering layers" (though they can occur near the sea surface). A new paper in Limnology and Oceanography shows that, rather than consisting of a random mixture of animals, these layers cont

• Tomato Plants Can Turn Caterpillars Into Cannibals

  10-07-2017 21:24 via feedproxy.google.com
  
  It's a twist of fate that wouldn't feel out of place in a horror movie: A platoon of caterpillars, young and hungry, descend on a defenseless tomato plant to feast, but as they begin to eat something goes terribly wrong. The leaves no longer satisfy, and they turn on each other in a cannibalistic frenzy — feeding wildly until just one, sated and content, remains.You can read it as a Carrie-like moral parable, perhaps, but bringing out caterpillars' carnivorous tendencie

• Decoding ants' coat of many odors

  10-07-2017 21:00
  
  It's a waxy layer that covers their bodies and is the source of the complex aromas that ants use to communicate. These odorant blends act like biochemical uniforms, identifying individual ants by caste, colony and species. In so doing it helps regulate the ants' behavior, allowing them to navigate the sophisticated social systems that has made ants one of the most successful families of animals on Earth.

• Does Artificial Intelligence Need A Psychologist To Be Fully Understood?

  Likening today’s AI to little children is a logic fail and creates a slippery slope: namely, it now calls for the pseudo-science of psychology to analyze AI’s behavior and thinking processes. This is like “they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.” (Matthew 15:14) ⁃ TN EditorEngineers are using cognitive psychology to figure out how AIs think and make them more accountable.

But, researchers reporting in Current Biology on July 10 have discovered that despite friendly relations between the sexes, particular males have a surprisingly strong advantage over others when it comes to fathering offspring. For example, researchers found in one group that the most reproductively successful bonobo male fathered more than 60 percent of the next generation.
