Big data… Plants… Planets… Universe…
A group of Florida Museum of Natural History scientists has issued a "call to action" to use big data to tackle longstanding questions about plant diversity and evolution and forecast how plant life will fare on an increasingly human-dominated planet. In a commentary published today in Nature Plants, the scientists urged their colleagues to take…

Complexity. Animals. Life. Death. Evolution. You.
In the beginning, life was small. For billions of years, all life on Earth was microscopic, consisting mostly of single cells. Then suddenly, about 570 million years ago, complex organisms including animals with soft, sponge-like bodies up to a meter long sprang to life. And for 15 million years, life at this size and complexity…

Row by row…
Just as children follow a rule to line up single file after recess, some materials use an underlying rule to assemble on surfaces one row at a time, according to the study done at PNNL, the University of Washington, UCLA, and elsewhere. Nucleation - that first formation step - is pervasive in ordered structures across…

Telling time…
In music, sports and other activities, we calculate movement in two different parts of the brain: One type of anticipatory timing relies on memories from past experiences. The other on rhythm. Both are critical to our ability to navigate and enjoy the world, and scientists have found they are handled in two different parts of…

Predict what is not…
Artificial neural networks - algorithms inspired by connections in the brain - have 'learned' to perform a variety of tasks, from pedestrian detection in self-driving cars, to analyzing medical images, to translating languages. Now, researchers are training artificial neural networks to predict new stable materials. (1) Using an unstable network. To predict the existence of…
