Brittle Starfish Make Tough Ceramics

An international research team led by the Department of Materials Science and Engineering at the Technion-Israel Institute of Technology has discovered how a beautiful, brainless brittle star can create material similar to tempered glass underwater at ambient conditions. The findings, published in the December 8 issue of Science, may open new bio-inspired routes for toughening brittle ceramics in various applications.

Climate scientists study the odds of a megadrought

To help untangle fact from speculation, Cornell climate scientists and their colleagues have developed a “robust null hypothesis” to assess the odds of a megadrought – one that lasts more than 30 years – occurring in the western and southwestern United States. The research was published online Dec. 8 in the Journal of Climate.

Native Fish Species at Risk Following Water Removal from the Colorado River

Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication in the journal PeerJ reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta.

NREL Develops Novel Method to Produce Renewable Acrylonitrile

A new study from the Energy Department’s National Renewable Energy Laboratory (NREL) establishes a novel catalytic method to produce renewable acrylonitrile using 3-hydroxypropionic acid (3-HP), which can be biologically produced from sugars. This hybrid biological-catalytic process offers an alternative to the conventional petrochemical production method and achieves unprecedented acrylonitrile yields.

Mathematicians crack 44-year-old problem

Zilin Jiang from Technion — Israel Institute of Technology and Alexandr Polyanskii from the Moscow Institute of Physics and Technology (MIPT) have proved László Fejes Tóth’s zone conjecture. Formulated in 1973, it says that if a unit sphere is completely covered by several zones, their combined width is at least π. The proof, published in the journal Geometric and Functional Analysis, is important for discrete geometry and enables new problems to be formulated.
