Pyrofusion: Desktop Nuclear Fusion works, but useless
«An astonishingly simple demonstration of nuclear fusion in a tabletop device has been performed, involving heating an ordinary crystal soaked in deuterium gas.»

« Crystal creates table-top fusion --
It won't solve our energy crisis, but could help treat cancer.

« By using a larger tungsten tip, cooling the crystal to cryogenic temperatures, and constructing a target containing tritium, the researchers believe they can scale up the observed neutron production 1000 times, to more than 106 neutrons per second.»

- Note, this is PyroFusion, in a pyroelectric crystal, not cold fusion.

Ordinary? [emphasis above supplied] The asymmetrical pyroelectrical effect is hardly ordinary.

Get this ... it works inside "lithium tantalate crystals". Gene Roddenberry was closer than anyone suspected with his Dilitium Crystals for the AntiMatter drive!

Multiple sightings of long-lost woodpecker reported
« Long believed to be extinct, a magnificent bird - the ivory-billed woodpecker - has been rediscovered in the Big Woods of eastern Arkansas. More than 60 years after the last confirmed sighting of the species in the United States, a research team today announced that at least one male ivory-bill still survives in vast areas of bottomland swamp forest.»

«Re-discovered ivory billed woodpecker still faces challenge to survival
The National Wildlife Refuge Association (NWRA) today hailed the announcement in today's Science Express that a thought-to-be extinct ivory-billed woodpecker has been discovered at Cache River National Wildlife Refuge in Arkansas, but expressed concern about its chances for survival. »

«Observers in eastern Arkansas have reported at least eight independent sightings of a bird that appears to be an ivory-billed woodpecker, a species widely thought to be extinct. A video clip of one bird, though blurry, shows key features, including the size and markings, indicating that the bird is indeed an ivory-billed woodpecker, according to John W. Fitzpatrick of Cornell University and coauthors of a paper released online today by Science.»

Researchers drill historic hole in atlantic ocean floor
«Researchers from the Integrated Ocean Drilling Program (IODP) have drilled into sections of the Earth's crust for the first time ever, and their findings could provide new insights about how Earth was formed. »
- Pretty deep, even if they did cheat by drilling into a sea-mount.

STEREO View of Space Weather
«The upcoming Solar TErrestrial RElations Observatory (STEREO) mission will help provide the big picture by using two nearly identical spacecraft to image the Sun and track its activity in high definition 3-D. Particularly crucial will be its observations of coronal mass ejections, or CMEs, the most powerful explosions in the solar system. Related to solar flares (scientists still don't really know which comes first), CMEs can pack the force of a billion megaton nuclear bombs. »
