One long-standing climate puzzle relates to the Late Eocene and Early Oligocene. Profound changes were underway. Globally, carbon dioxide levels were falling and the hothouse warmth of the dinosaur age and Eocene Period was waning. In Antarctica, ice sheets had formed and covered much of the southern polar continent. But what exactly was happening on [...]

Researchers have developed a new breast biopsy technique that could lead to decreased procedure times, and reduced patient discomfort and morbidity, according to a new study. The new technique uses a mechanical arm to guide the needle for the biopsy, and has a braking system to allow for accurate placement of the needle and to [...]
