team of physicists has found the first direct evidence of pear
shaped nuclei in exotic atoms. During the late Pleistocene, a
diverse assemblage of large-bodied mammals inhabited the
"mammoth steppe" of northern Eurasia and Beringia. Of the large
predators -- wolves, bears, and big cats -- only the wolves and
bears were able to maintain their ranges well after the end of
the last ice age. A new study suggests that dietary flexibility
may have been an important factor giving wolves and bears an
edge over saber-toothed cats and cave lions. In many
neurodegenerative diseases the neurons of the brain are over-
stimulated and this leads to their destruction. After many
failed attempts and much scepticism this process was finally
shown last year to be a possible basis for treatment in some
patients with stroke. But very few targets for drugs to block
this process are known. Steelmaking, a major emitter of climate-
altering gases, could be transformed by a ne
