ANN ARBOR, Mich.— Nature teems with examples of evolutionary arms races between predators and prey, with the predator species gradually evolving a new mode of attack for each defensive adaptation that arises in the prey species.
These adaptations are often portrayed as reciprocal, with prey and predator acting as two sides in an endless evolutionary tug of war known as co-evolution. (more…)
*Feeding habits haven’t always been what they are today*
The feeding habits of mammals haven’t always been what they are today, particularly for omnivores.
Some groups of mammals almost exclusively eat meat–take lions and tigers and other big cats as examples.

UA astronomy students Kevin Hardegree-Ullman and Jake Turner designed, proposed, conducted and presented research on two recently discovered planets outside of our solar system while they were still undergraduates.
Deep in the cosmos, alien planets are circling distant stars, waiting to be pierced by the far-reaching gaze of Earth-bound telescopes. Some are Earth-like and have the potential to harbor liquid water and maybe even life. Others are enormous, gassy giants. All of them are different than any planet we know. (more…)
*Discovery Could Improve Substance Abuse Treatment*
COLUMBIA, Mo. – Tipping back one too many cocktails during an individual’s early 20s doesn’t correlate to a personal sense of immaturity; however if this habit doesn’t stop as they reach age 30, young adults can feel psychologically underdeveloped, according to a University of Missouri study. Helping young adults acknowledge their mental impulse to “sober up” as they mature can improve substance abuse intervention programs.
“When a heavy drinking 30-year-old comes in for therapy and says he doesn’t feel like an adult, we can present this study and suggest that cutting back on alcohol could help him feel more mature,” said lead researcher Rachel Winograd, a doctoral student in psychology at MU. (more…)

*UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness, Alzheimer’s disease*
In the world’s largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain’s resistance to a variety of mental illnesses and Alzheimer’s disease.
Published April 15 in the advance online edition of the journal Nature Genetics, the study also uncovers new genes that may explain individual differences in brain size and intelligence. (more…)
The iceberg wasn’t the only culprit in the Titanic’s sinking; In this edition of “Science Xplained,” scientist Ainissa Ramirez demonstrates how the metal rivets that held the ship together became brittle in the frigid waters and broke apart on impact with the iceberg, likely contributing to the enormity of the tragedy.
