A new study deals a blow to the theory that early humans moved out of Africa and completely replaced local populations elsewhere in the world. The findings suggest there was some interbreeding between our African ancestors and the residents of areas where they settled.
A University of Utah biologist used high-speed video to identify a tadpole's distinct way of eating. Instead of filtering food from water like other frog larvae, the polliwog extends its tube-shaped mouth, and then sucks in immature shrimp, water fleas or other prey.
Scientists at the University of Utah and in Japan have discovered a gene that ensures the flatworm's brain develops within its head. When the "brains everywhere" gene is silenced, brain material develops throughout the body, including the worm's tail.
In a study that may improve animal breeding and reveal more about how animals detect odors, Utah and Oregon scientists learned how proteins help a female sex attractant stimulate male elephants so they mate, and how one protein may end their arousal.

The University of Utah trustees approved honorary degrees for four outstanding individuals and gave their nod of approval to Chief Justice Christine Durham as this year's commencement speaker. Honorary degree recipients include James E. Faust, Louis H. and Ellen Callister and Jon Jory, who will be recognized during graduation ceremonies on May 10.
By combining a chemotherapy drug with a sugar that normally helps cancer move through the human body, University of Utah researchers developed a new medication to track down, invade and destroy tumor cells as they spread or metastasize.
A gene that makes human blood clot also is found in bloodless fruit flies and helps cone snails produce an epilepsy drug. Biologists learned the gene existed 540 million years ago, raising a mystery over its ancient role and suggesting an early origin for "junk DNA."
University of Utah bioengineers made tiny, living Olympic Rings from nerve cells to demonstrate technology that someday might help repair spinal cord injuries from accidents and brain damage from Alzheimer's, Parkinson's or other diseases.
A study by the University of Utah's Moran Eye Center shows vision can be successfully preserved in rats that go blind in the first months of life. The study sets the stage for vision restoration in humans with macular degeneration and other retinal diseases.
Most cystic fibrosis (CF) patients who receive lung transplants either gain no benefit from the surgery or would live longer if they kept their own diseased lungs, according to a new study by University of Utah researchers.
A University of Utah study apparently overturns the belief that fragile X syndrome is too complex to be treated effectively. The findings raise hope that existing drugs might be used within a few years to treat the most common inherited form of mental retardation.
University of Utah biologists trained alligators to walk on a treadmill during studies that revealed new clues about how dinosaurs breathed.
When thousands of people visit the greater Salt Lake City area for the February 2002 Olympic Winter Games, University of Utah researchers will be monitoring traffic jams and other highway problems from the university's Utah Traffic Lab.
