It really was a scorcher this spring and summer - 26 cities in the Northeast set records for average temperatures this year, reports the Northeast Regional Climate Center at Cornell.
New interdisciplinary research on photocathodes by physics graduate student Siddharth Karkare has the potential to dramatically improve accelerator performance.
Clam fossils from the middle Devonian era – some 380 million years ago – now yield a better paleontological picture of the capacity of ecosystems to remain stable in the face of environmental change.
With a $6.5 million grant from NSF, an international consortium of researchers will use observatories around the world, including Arecibo, to find and use pulsars to detect gravitational waves. (Aug. 23, 2010)
