When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.
Although morphine has been the gold-standard treatment for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells.
A cellular protein from a family involved in several human diseases is crucial for the proper production and release of insulin, new research has found, suggesting that the protein might play a rol
Contrary to concerns that the human papillomavirus vaccine might promote promiscuity, a national survey of girls and young women found that the majority of respondents did not believe the HPV vaccine protected them against other sexually transmitted infections.
Color is normally thought of as a fundamental attribute of an object: a red Corvette, a blue lake, a pink flamingo. Yet despite this popular notion, new research suggests that our perception of color is malleable, and relies heavily on biological processes of the eye and brain.
A 9-foot dinosaur from northeastern China had evolved all the hallmark anatomical features of Tyrannosaurus rex at least 125 million years ago. University of Chicago paleontologist Paul Sereno and five co-authors describe the newly discovered dinosaur in the Sept. 17 Science Express, advanced online edition of the journal Science.
Previous research has found that children raised in homes without a biological father have sex earlier than children raised in traditional nuclear families. Now a new study that used a novel and complex design to investigate why this is so challenges a popular explanation of the reasons.
CHICAGO (Aug. 24, 2009) -- The battle of the sexes rages on, this time from the trading floor.
ARGONNE, Ill. (Aug. 19, 2009) -- Scientists from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Chicago's Brain Tumor Center have developed a way to target brain cancer cells using inorganic titanium dioxide nanoparticles bonded to soft biological material.
Divorce and widowhood have a lingering, detrimental impact on health, even after a person remarries, research at the University of Chicago and Johns Hopkins University shows.
WASHINGTON -- Though digital technologies and high-speed communications have significantly expanded the capabilities of scientists -- allowing them to analyze and share vast amounts of data -- these technologies are also raising difficult questions for researchers, institutions, and journals.
ARGONNE, Ill. (June 18, 2009) -- Scientists at the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago have reached a milestone in the study of emergent magnetism.
Plants or meat: That's about all that fossils ever tell paleontologists about a dinosaur's diet. But the skull characteristics of a new species of parrot-beaked dinosaur and its associated gizzard stones indicate that the animal fed on nuts and/or seeds. These characteristics present the first solid evidence of nut-eating in any dinosaur.

The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict, according to the University of Chicago postdoctoral scholar Philipp Heck and his international team
of colleagues.
