New study challenges 'critical period' in childhood vision development

...ense congenital cataracts in both eyes. The woman lived as a blind child for 12 years before she received treatment. Now, twenty years after her surgery, the researchers found that she is able to discern between separate objects, determine depth, localize faces amongst a background of natural scenes, and...

Tundra disappearing at rapid rate

...ce tundra landscapes--forcing out the species that lived there. This shift can happen at a much faster speed than scientists originally thought, according to a new University of Alberta study that adds to the growing body of evidence on the effects of climate change. The boundary, or treeline, between fo...

Discovery of new cave millipedes casts light on Arizona cave ecology

...northern Arizona was warmer and wetter, millipedes lived in leaf litter. As the climate warmed, they sought refuge in caves, where the subterranean realm provides more constant climatic conditions enabling their survival. Representing two distinct species (one occurring in one cave on the South Rim, the...

From the deep -- Researchers find new species of sea anemone

..."whale fall." The anemones that Daly received once lived on the bones of a dead whale some 1.8 miles (3,000 meters) below sea level in a region of the Pacific Ocean called Monterey Canyon, roughly 25 miles off the coast of Monterey, Calif. All of the specimens currently in Daly's collection came from this ...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

...ied significantly faster than control flies, which lived two to four times as long as the sick ones. "We want to know how the internal clock knows the animal is infected, and how does the immune system know that you are not sleeping properly"" said Schneider. "How do those messages get sent back and for...

Asexual worm quickly adapts to soil contamination

...taminated culturing medium they laid more eggs and lived for longer than the nematodes from the clean soil. Asexual The rapid adaptation to the environment in an asexual species is an interesting finding. It contradicts the general opinion that asexual species have low adaptive potential and that t...

Amphibians in losing race with environmental change

...Earth. They were around before the dinosaurs, have lived in periods with very different climates, and continued to thrive while many other species went extinct. But right now, they just can't keep up." It has been estimated that the rate of plant and animal extinction is greater now than any known in th...

Lessons from the orangutans: Upright walking may have begun in the trees

Ice Age extinction claimed highly carnivorous Alaskan wolves

...d one more: a highly carnivorous form of wolf that lived in Alaska, north of the ice sheets. Wolves were generally thought to have survived the end-Pleistocene extinction relatively unscathed. But this previously unrecognized type of wolf appears to have vanished without a trace some 12,000 years ago. ...

In nature, proteins sweep up nanoparticles

...alling cards left behind by microbes that may have lived eons ago. The presence of fine particulate sulfides in minerals is one such biosignature, although it is only suggestive of life. Now, the presence of sulfide nanoparticles intermingled with proteins promises to be a definitive biosignature. ...

CT scan reveals ancient long-necked gliding reptile

Because the researchers did not want to cut up the sheet of rock in which the fossilized glider was embedded, they gave up total resolution of ...
