Protein Attributed to Membrane Repair Identified - Mechanism May Revolutionize Therapy in Human Disease

Researchers at UMDNJ-Robert Wood Johnson Medical School have identified the protein MG53, as a key initiator of membrane repair in damaged tissue. The study, released today in Nature Cell Biology, is the first to specifically pinpoint a protein responsible for promoting cell repair.

ISS repair spacewalk completed

Two astronauts on the US space shuttle Endeavour have completed a seven-hour spacewalk as part of an effort to repair the International Space Station.

NASA Try to Repair Ailing Hubble

NASA Try to Repair Ailing Hubble: NASA engineers have rebooted the computer, which controls most science instruments aboard the orbiting Hubble telescope, in an attempt to bring the ailing space observatory back to life.

Astronauts carry on repair work

Spacewalking astronauts performed more repair work on a jammed joint at the international space station, keeping a tight grip on all their tools so nothing would get away this time.

New Role For Critical DNA Repair Molecule In Immune System

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA. New research published in Nature shows for the first time that a molecule devoted to DNA repair plays a broader role in this genetic reshuffling — called recombination — than scientists had thought.

Astronauts face hardest spacewalk to finish repair

CAPE CANAVERAL, Fla. (AP) _ Astronauts up on the international space station faced the longest and hardest spacewalk of their mission Saturday, a seven-hour-plus excursion to wrap up repair work on a gummed-up joint.

Predicting Boundary-Layer Transition on Space-Shuttle Re-Entry

The BLT Prediction Tool (“BLT” signifies “Boundary Layer Transition”) is provided as part of the Damage Assessment Team analysis package, which is utilized for analyzing local aerothermodynamics environments of damaged or repaired space-shuttle thermal protection tiles. Such analyses are helpful in deciding whether to repair launch-induced damage before re-entering the terrestrial atmosphere. Given inputs that include re-entry trajectory and attitude parameters, air density, air temperature, and details of each damage or repair site, the BLT Prediction Tool calculates expected times of laminar-to-turbulent transition onset of the boundary-layer flow during re-entry. (These times help to define the proper aerothermodynamic environment to use in subsequent thermal and stress analyses of local structural components.

LHC Repair To Cost At Least $21 Million

ThanatosMinor writes "September's quench at the Large Hadron Collider is going to cost CERN at least $21 million and delay future collisions until June of 2009 at the earliest. Enjoy your last few months outside of an event horizon."

Hubble repair mission delayed yet again

The galaxy on the left, which appears edge on, appears quiescent aside from a bright ring of recently formed stars. Its partner galaxy, at the right, has a blue ring of star formation. This ring most likely formed after the galaxy on the left plowed through the galaxy on the right and generated concentric, outwardly propagating density waves — similar to the waves created when a pebble is cast into a pond.

NASA makes repair to Hubble Space Telescope

The ailing Hubble Space Telescope could be snapping pictures of the heavens again as early as Saturday after engineers fixed one of the problems that has largely shut down the instrument for the last three weeks.
