Creeping climate change in the Southwest appears to be having a
negative effect on pinyon pine reproduction, a finding with
implications for wildlife species sharing the same woodland
ecosystems, says a University of Colorado Boulder-led study.
According to Einstein, whenever massive objects interact, they
produce gravitational waves -- distortions in the very fabric of
space and time -- that ripple outward across the universe at the
speed of light. While astronomers have found indirect evidence
of these disturbances, the waves have so far eluded direct
detection. Ground-based observatories designed to find them are
on the verge of achieving greater sensitivities, and many
scientists think that this discovery is just a few years away.
Scientists have disagreed for many years over the precise cause
for a period of cooling global temperatures that began after the
Middle Ages and lasted into the late 19th century, commonly
known as the Little Ice Age. Physicists at JILA on the CU-
Boulder campus have for the firs
