Special session at the 2012 ARVO Annual Meeting ARVO is pleased to host a presentation of the one-year results from the U.K.'s Inhibition of VEGF in Age-related Choroidal Neovascularisation (IVAN) study and the two-year results of the Comparison of Age-related Macular Degeneration Treatments Trials (CATT) trial. These two multicenter randomized clinical trials, sponsored by the National Institute of Health Research in the United Kingdom and the National Eye Institute, respectively,...

The debate over hydraulic fracturing has recently focused on the rise in seismicity throughout the primarily stable interior of the United States. These intraplate regions, though not unfamiliar with earthquakes, have been experiencing an increased amount of seismic activity in the last decade. This unusual increase is likely to be caused in part by wastewater disposal practices related to natural gas production. With such a sensitive issue it is important to keep the facts in perspective: No...

A new genre of electric power-generating stations could supply electricity for more than a half billion people by tapping just one-tenth of the global potential of a little-known energy source that exists where rivers flow into the ocean, a new analysis has concluded. A report on the process – which requires no fuel, is sustainable and releases no carbon dioxide (the main greenhouse gas) – appears in ACS' journal Environmental Science & Technology. Menachem Elimelech and...

More than half-a-century ago, the Dutch theoretical physicist Hendrik Casimir calculated that two mirrors placed facing each other in a vacuum would attract. The mysterious force arises from the energy of virtual particles flitting into and out of existence, as described by quantum theory. Now Norio Inui, a scientist from the University of Hyogo in Japan, has predicted that in certain circumstances a reversal in the direction of the so-called Casimir force would be enough to levitate an...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
