Spallation Neutron Source sees first target replacement
...rget is changed, which ultimately at full power could occur several times a year.
The old target will be studied to gauge how three years of proton bombardment
have affected its materials.

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. Life on Mars may have appeared near the same time. As only life can p...
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.

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...

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...
