Hubble Pix Show Earliest Galaxies (Science/Technology, 11 articles)
|
Astronomers unveiled the deepest-ever look into the distant reaches of the universe Tuesday, revealing baby galaxies that lit up the cosmic darkness soon after the big bang. Scientists hailed the two new long-exposure images, taken by the Hubble Space Telescope, as some of the most awe-inspiring science ever to come from the orbiting observatory. Officials said the Hubble image contains an estimated 10,000 galaxies, and astronomers around the world will now search in this field of view for the most distant objects known. Senators asked NASA to seek an outside analysis of the agency's plans to cancel a repair mission to the Hubble Space Telescope, a decision that would eventually lead to the loss of the orbiting observatory. The telescope, which has provided scientists with a wealth of information on space and its far-flung galaxies, was designed to be serviced by the space shuttle. This historic image takes astronomers close to the Big Bang itself, unveiling the first galaxies that emerged from the end of the so-called "dark ages". The Hubble Ultra Deep Field image reveals some of the farthest and youngest galaxies ever seen, whose light was previously too faint to be detected.

$750,000 contract offered for Canadian-built Mars rover (Science/Technology, 4 articles)
|
Despite every failed mission since, including NASA's Mars Polar Lander that simply vanished just before entering Mars's atmosphere in 1999, the mission to Mars pushes forward. Now we're sending the latest technology, the newest remote-controlled land rovers, to study the planet in preparation for the next giant leap for mankind - a manned mission to Mars. Donna Shirley said going to the moon could become an expensive diversion.

Got a heavy load to tote? Strap on BLEEX (Science/Technology, 5 articles)
|
Scientists at the Robotics and Human Engineering Laboratory at the University of California-Berkeley designed the prototype exoskeleton, called BLEEX - the Berkeley Lower Extremities Exoskeleton. It's a pair of mechanical metal leg braces complete with a power unit and backpack-like frame to carry loads while walking, running, bending or climbing. Move over, Bionic Man, and make room for BLEEX the Berkeley Lower Extremities Exoskeleton with strap-on robotic legs designed to turn an ordinary human into a super strider.

Study: Women may hold hidden reserves of eggs (Science/Technology, 7 articles)
|
For decades, scientists thought every female was born with a set number of eggs and that those eggs ran out over time, leading to the menopause. Scientists have found hints that mammals' ovaries produce new eggs throughout life, a finding that might herald new treatments for infertility and the menopause. For more than half a century, the medical textbooks have said that women are born with a fixed number of eggs, and the supply eventually runs out in middle age.

Test may aid decision on breast-cancer treatment (Science/Technology, 7 articles)
|
A first-of-its-kind genetic test soon will be available to help women with breast cancer make a crucial decision: whether to undergo the rigors of chemotherapy. A drug that has shown promise against advanced breast cancer might work well in women diagnosed with early disease, offering a new treatment option and a stronger way to thwart cancer recurrences, scientists report today. In the international project, a drug called exemestane (sold as Aromasin) worked better than tamoxifen, one of medicine's mainstays, in preventing new tumor development.
