. . . and the big bird that didn’t
The California condor, one of today's largest and rarest birds, may have survived the last ice age because of its varied diet.
- Paleontology
The big fish that went away . . .
Fossils found near Charleston, S.C., suggest that an extinct species of billfish related to today's swordfish and marlin would easily exceed the lengths documented for world-record specimens of those oft-sought sports fish.

Dino Dwarf: Island living may have led to ancient downsizing
Fossils unearthed at a German quarry hint that members of one species of dinosaur that lived in the region about 152 million years ago evolved to be abnormally small because of the constraints of its island ecosystem.
- Paleontology
Irish elk survived after ice age ended
New fossil finds indicate that the so-called Irish elk, previously thought to have died out at the end of the last ice age, survived in some spots for several millennia more.

Fighting Water with Water: To lift the city, pump the sea beneath Venice
With technology commonly used in oil fields, engineers could inject large volumes of seawater into sandy strata deep beneath Venice, Italy, to reverse the ground subsidence that plagues the city.
- Paleontology
Fossil birds sport a new kind of feather
Two fossil specimens of a primitive, starling-size bird that lived about 125 million years ago have tail feathers that may hold the clues to how feathers originated.

Early Bird: Fossil features hint at go-get-’em hatchlings
A well-preserved, 121-million-year-old fossilized bird embryo has several features that suggest that the species' young could move about and feed themselves very soon after they hatched.

Life Landed 2.6 Billion Years Ago
Unusually carbon-rich rocks found in eastern South Africa may push back the evidence of life on land to 2.6 billion years ago, more than twice the current age of indisputably terrestrial organisms.

Change in the Weather? Wind farms might affect local climates
Large groups of power-generating windmills could increase wind speed, temperature, and ground-level evaporation, thereby influencing a region's climate.

Extra rainfall may stem warming in Midwest
Increased precipitation in parts of the Midwest may reduce the temperature increases expected to occur in the next few decades as a result of global warming.

What’s Wrong with This Picture?
Scientists and educators increasingly are using analyses of bad science in movies, as well as the good, to inform the public about scientific facts and principles.

Nobel prizes: The sweet smell of success
Nobel prizes in the sciences went to research on olfactory genes, subatomic particles, and the molecular kiss of death.
