PHYSICISTS CLARIFY EXOTIC FORCE, BUT NO 'THEORY OF EVERYTHING' YET

The quest for a single theory that unites all of the universe's fundamental forces has thus far eluded physicists, but that has not stopped a team of them from clearing the way for nanotechnologists while they look for it.

The group, which includes Purdue University's Ephraim Fischbach, has recently completed research that improves our understanding of how tiny objects placed very close together can influence each other. Their experiment, which involves the behavior of a minuscule gold ball as it moves over different substances, shows that gravity behaves exactly as Isaac Newton predicted, even at small scales.

ATLANTIC OCEAN GETTING MORE FRESH WATER IN RECENT DECADES, June 18
Large regions of the North Atlantic Ocean have been growing fresher since the late 1960s as melting glaciers and increased precipitation, both associated with greenhouse warming, have enhanced continental runoff into the Arctic and sub-Arctic seas. Over the same time period, salinity records show that large pulses of extra sea ice and fresh water from the Arctic have flowed into the North Atlantic. But, until now, the actual amounts and rates of fresh water accumulation have not been explicitly known.

G-ZERO FINDS THAT GHOSTLY STRANGE QUARKS INFLUENCE PROTON STRUCTURE, June 20
In research performed at the Department of Energy's Jefferson Lab, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration, an international group of 108 physicists from 19 institutions and was presented at a Jefferson Lab physics seminar June 17.
