A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians. This theorized image of such a drastic adaptation to changing environmental conditions, however, may, itself, be evolving into a new picture.

Recovery Reversal Seen in Oregon Study of Returning Concussed Athletes
EUGENE, Ore. -- When are athletes who have suffered concussions ready to return to action? A new University of Oregon study has found that high school athletes who head back on the field with medical clearance within 60 days experience a significant regression in their abilities to simultaneously walk and do simple mental tasks.

Oregon Chemists Eye Improved Thin Films with Metal Substitution
EUGENE, Ore. – (July 21, 2014) – The yield so far is small, but chemists at the University of Oregon have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics and alternative energy devices.

Oregon Geologist Says Curiosity's Images Show Earth-like Soils on Mars
EUGENE, Ore. -- Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says University of Oregon geologist Gregory Retallack, based on images and data captured by the rover Curiosity.

Sleep Quality And Duration Improve Cognition in Aging Populations
EUGENE, Ore. -- (June 16, 2014) -- Maybe turning to sleep gadgets -- wristbands, sound therapy and sleep-monitoring smartphone apps -- is a good idea. A new University of Oregon-led study of middle-aged or older people who get six to nine hours of sleep a night think better than those sleeping fewer or more hours.

Oregon Researchers Capture Handoff of Tracked Object Between Brain Hemispheres
EUGENE, Ore. -- When tracking a moving object, the two halves of the human brain operate much like runners successfully passing a baton during a relay race, says a University of Oregon researcher. In a study online ahead of print in Current Biology, electroencephalogram (EEG) measured brainwaves from healthy young adults revealed how information about an attended object -- one being watched closely -- moves from one brain hemisphere to the other.
