Ancient Otter Tooth Found in Mexico Suggests Mammals Migrated Across America

An ancient otter tooth recently discovered in Mexico suggests certain mammals migrated across America during the Miocene geologic epoch, roughly 23 million to 5.3 million years ago. The new hypothesized route questions other theories such as migrations above Canada and through Panama, and has implications for a much larger biologic event — the Great American Biotic Interchange, when land bridges were formed and animals dispersed to and from North America and South America.

MU Doctor Reminds Wire BBQ Grill Brushes Can Cause Injuries

Wire-bristle grill brushes are used frequently for cleaning food residue from grill grates, but loose bristles can fall off the brush during cleaning and end up in the grilled food. If consumed, wire bristles can lead to injuries in the mouth, throat and tonsils. An otolaryngologist at MU Health Care would like to remind the public that these injuries can be prevented.

Small Scale, Big Improvements

Chemical reactions that make improvements in water purification and batteries possible occur at scales too small to see. A team including a UD researcher has developed a way to produce real-time observations documenting the reactions that happen between liquids and solids.

Infant Sun Protection: How Parents Can Keep Their Baby Safe

Skin cancer is the most common cancer in the United States, and it only takes one blistering sunburn during childhood or adolescence to nearly double a person’s chance of developing melanoma, the deadliest form of skin cancer, later in life. This is why it’s imperative, say dermatologists from the American Academy of Dermatology, that parents do everything they can to protect their infants from the sun’s harmful ultraviolet rays and teach their children healthy sun care habits – starting at an early age.

Researchers Find a Surprise Just Beneath the Surface in Carbon Dioxide Experiment

An X-ray technique, coupled with theoretical work, revealed how oxygen atoms embedded very near the surface of a copper sample had a more dramatic effect on the early stages of the reaction with carbon dioxide (CO2) than earlier theories could account for. This information could prove useful in designing new types of materials to further enhance reactions and make them more efficient in converting carbon dioxide into liquid fuels and other products.

'DNA Is a Bully' That Hustles Transcribers to Targets

"DNA is a bully." That's how researcher Jeffrey Skolnick sums up the dominant power of DNA motion among the forces acting upon transcription factors as they move through DNA's winding thickets to their target sites. He and Edmond Chow have programmed a very large, unique simulation that tests and corroborates the hypothesis.
