...-tight blackout shades, and some of them will wear specially made Mars watches that record an additional 39 minutes, 35 seconds every day. But when rover team members step outside, they will be bombarded with external stimuli running on the 24-hour clock to which their bodies are accustomed.

"They represent those few extreme individuals in the population with an intense desire or compulsion to run," he says. To understand what drives these mice to run faster and farther th...First view of giant crabs - at home on the slope
...stitute (TAFI), University of Tasmania. "We used a specially designed camera platform towed behind a research vessel to provide a tremendously exciting first look at the type of habitat that supports the giant crab fishery," says project scientist, Dr. Alan Williams, from CSIRO Marine Research in Hobart.

At that point, a team of two veterinarians inserts a hose with oxygen-rich water into the shark's mouth to keep them breathing while monitoring their condition. Meanwhile, a group of scientists attach the tag to the dorsal fin to...Breast cancer susceptibility genes play role in DNA repair
... colleagues created a line of cells that produce a specially tagged version of BARD1 a protein known to interact with BRCA1. The tag allowed Shiekhattar to isolate BARD1 and any protein found with it.

"When you have really low levels of timeless, you also disrupt the other clock genes," Barnes said. "You get an uncoupling. The clock is very much in disarray." ...Manual, low-tech method for 2nd trimester abortions found safe and effective
