It's easy to get in a jam. But it's much harder to explain exactly how or when it started. Scientists still aren't sure what causes clogs in flowing macroscopic particles, like corn, coffee beans and coal chunks. But new experiments by Duke physicist Robert Behringer and his colleagues suggest that when particles undergo a force called shear strain, they jam sooner than expected. The results appear in the Dec. 15 issue of Nature. Shear strain is sort of like cupping sand between your...

The manufacture of parts by compaction and sintering involves filling a die with metal powder. Research scientists have simulated this process for the first time to achieve an evenly distributed powder density. This improves the cost-efficiency of sintering. It all happens very quickly: the feed shoe, configured as an open-bottomed box, moves across a surface in which a recess forms the shape of the desired part. The fine-grained metal powder dropping from the feed shoe settles in the mold....

The U.S. Food and Drug Administration announced the recall of Publix-brand GreenWise chocolate and vanilla whey protein powder due to a labeling error. The FDA said the recall was initiated because the powder might contain undeclared milk ingredients, posing a health hazard for people with milk allergies. The recalled powders -- with expiration dates of 05/2012 or 06/2012 -- were distributed to Publix stores in Florida, Georgia, South Carolina, Alabama and Tennessee. The products may be...

University of Chicago researchers have discovered dry granular materials such as sand, seeds and grains have properties similar to liquid. The physicists from the university's Materials Research Science and Engineering Center said the granular materials form water-like droplets when poured from a given source. The researchers said their finding could be important to a wide range of industries that use fluidized dry particles. It was previously thought dry particles lacked sufficient surface...
