Using multi-slice electron ptychography on a PMN-PT alloy, MIT-led researchers directly imaged a hierarchy of polar and chemical structures, finding that polarization regions are much smaller than leading simulations predicted.

Six months of observations of the third interstellar object ever detected have uncovered water, methane, and hydrogen cyanide in its coma--and a Jupiter flyby on March 16 could yield the closest-ever look at an interstellar visitor.

A team led by the University of Chicago has named Spinosaurus mirabilis, a scimitar-crested, fish-eating theropod found 500–1,000 km from the nearest ancient sea, reshaping what scientists know about where spinosaurs lived.
