'Big Picture' Of Brain Changes May Be Crucial To Recovery From Stroke

Hubble Captures Outburst From Comet Targeted By Deep Impact
In a dress rehearsal for the rendezvous between NASA's Deep Impact spacecraft and comet 9P/Tempel 1, the Hubble Space Telescope captured dramatic images of a new jet of dust streaming from the icy comet. The images are a reminder that Tempel 1's icy nucleus, roughly the size of central Paris, is dynamic and volatile. Astronomers hope the eruption of dust seen in these observations is a preview of the fireworks that may come 4 July, when a probe from the Deep Impact spacecraft will slam into the comet, possibly blasting off material and giving rise to a similar dust plume. Freedom Flight: Black South African Kid's Homemade Paraglider Leads to

Drug Found Effective In Treating, Preventing Breast Cancer
A new study of an estrogen-derived drug shows promise as a treatment for breast cancer and breast cancer metastases to bone. In animal studies it effectively targeted breast cancer cells; prevented the spread of breast cancer cells to bone and protected bone from osteolysis, which is a type of bone metastasis in which the bone is eaten away by cancer cells. Clinical trials are the next step. [Ironic] An Italian pensioner committed suicide after his wife fell in
