Since the dawn of the biological sciences, humankind has struggled to comprehend the relationships among the major groups of “jointed-legged” animals — the arthropods. Now, a team of researchers has finished a completely new analysis of the evolutionary relationships among the arthropods, answering many questions that defied previous attempts to unravel how these creatures were [...]
Researchers have for the first time identified a key mechanism that makes certain cells become tumorous in the brain. The resulting tumors occur most often spontaneously but can also occur in numbers as part of the inherited disease neurofibromatosis type 2.
Dolphins are the only species besides humans known to harbor infections of multiple papillomavirus types, which are known to be linked with cervical cancer in women. As a result, dolphins may be the ideal model for the study of cervical cancer in women.
Contrast-enhanced magnetic resonance imaging may help physicians differentiate between rheumatoid arthritis and psoriatic arthritis in the hand and wrist enabling more targeted therapies unique to each condition, according to a study. Contrast-enhanced MRI uses contrast media to improve the visibility of internal bodily structures.
Dark energy, habitable planets around other stars, and the mysterious nature of our own Sun, have been chosen by the European Space Agency as candidates for two medium-class missions to be launched no earlier than 2017.

Researchers have looked at how professionals in different occupational groups seek and use information and keep updated after finishing their education. The results show that teachers seek information they can use in their own teaching and that librarians focus on helping library users find information, while nurses just don’t have the time.
New research shows a strong link between the diversity of organisms at the bottom of the food chain and the diversity of mammals at the top. Throughout the last 30 million years, changes in the diversity of whale species living at any given time period correlates with the evolution and diversification of diatoms, tiny, abundant [...]
Scientists are gaining a better understanding of the molecular mechanism at play in mild traumatic brain injury (mTBI), commonly called concussions. Although mTBI affects over one million people each year in the United States, it is generally ignored as a major health issue.

Once described by Jacques Cousteau as the “world’s aquarium,” the marine ecosystems of the Gulf of California are under threat. Destructive new fishing methods are depleting the sea’s habitats, creating areas that are ghosts of their former existences.

Public health officials and health care providers need to step up their efforts to reduce Americans’ increasing rates of high blood pressure and better treat those with the condition, which triggers more than one-third of heart attacks and almost half of heart failures in the United States each year, says a new report.
