New Drug Protects Against Radiation Damage

...lt to find something that won't protect at least some cancer cells," he said. Any drug treatment that allows some cancer cells to survive radiation bombardment falls short of complete protection, Lawrence added. "Will it really protect in all people?" he asked. "The drug stimulates cells in the body to mak...

Life on Earth came from other planets

... struck or become part of the newly forming Earth. Life appeared a few hundred million years after the Earth's creation during a period of heavy bombardment by comets and moon-sized asteroids produced by the supernova of the parent star.

Scientists confirm that parts of earliest genetic material may have come from the stars

...illion years ago large numbers of rocks similar to the Murchison meteorite rained down on Earth at the time when primitive life was forming. The heavy bombardment would have dropped large amounts of meteorite material to the surface on planets like Earth and Mars. Co-author Professor Mark Sephton, also of Im...

Did the solar system 'bounce' finish the dinosaurs?

...for Astrobiology, said: Its a beautiful match between what we see on the ground and what is expected from the galactic record. The periods of comet bombardment also coincide with mass extinctions, such as that of the dinosaurs 65 million years ago. Our present position in the galaxy suggests we are now very c...

Leading cause of death in 'preemies' might be controlled by resetting a molecular switch

...LR4 receptors are primed to recognize pathogenic bacteria and sound the alarm. But Hackams group found that the stresses of oxygen deprivation and bombardment by bacterial toxins, conditions that can occur in premature infants with underdeveloped lungs, stimulate too much production of TLR4. Like an unstoppa...

Lab-on-a-chip could speed up treatment of drug-resistant pneumonia

... of drug-resistant pneumonia, cutting down the wait from days to hours. The technology could also help in the development of new drugs. The constant bombardment by antibiotics and disinfectants has bred strains of super-bugs that only respond to very specific drugs. These super-bugs often lurk in hospitals, wh...
