Answer to restoring lost island biodiversity found in fossils
Many native species have vanished from tropical islands because of human impact, but University of Florida scientists have discovered how fossils can be used to restore lost biodiversity.
CASIS research set for launch aboard SpaceX mission to space station
The fall marks a new school year, a new football season and another commercial cargo flight to the International Space Station. In September, SpaceX's Dragon spacecraft is scheduled to blast off to the orbital ...
Nano engineering advances bone-forming material
Murdoch University nanotechnology researchers have successfully engineered synthetic materials which encouraged bone formation in sheep.
