Two artificial intelligences talk to each other      (via sciencedaily.com)     Original source 

Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team has succeeded in modelling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a 'sister' AI, which in turn performed them.

The atlas of unburnable oil in the world      (via sciencedaily.com)     Original source 

In order to limit the increase in global average temperature to 1.5 C, it is essential to drastically reduce carbon dioxide emissions in the atmosphere. This would mean not exploiting most of the existing coal, conventional gas and oil energy resources in regions around the world, according to new research. The study presents the atlas of unburnable oil in the world, a world map designed with environmental and social criteria that warns which oil resources should not be exploited to meet the commitments of the Paris Agreement signed in 2015 to mitigate the effects of climate change.

AI for astrophysics: Algorithms help chart the origins of heavy elements      (via sciencedaily.com)     Original source 

The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time. Testing this theory and answering other astrophysical questions requires predictions for a vast range of masses of atomic nuclei. Scientists are using machine learning algorithms to successfully model the atomic masses of the entire nuclide chart -- the combination of all possible protons and neutrons that defines elements and their isotopes.

Water droplet spun by sound screens for colon cancer      (via sciencedaily.com)     Original source 

Mechanical engineers have devised a diagnostic platform that uses sound waves to spin an individual drop of water up to 6000 revolutions per minute. These speeds separate tiny biological particles within samples placed in a very light disc sitting on top of the spinning drop. The technique could allow new point-of-care applications ranging from precision bioassays to cancer diagnosis. The technique requires less time and sample volume while inflicting less damage to delicate exosomes.
