A new process for producing titanium is significantly less expensive and less energy-intensive than conventional
methods. Being developed by
SRI International,
Calif., the process takes fewer steps, uses less energy, and pro-
duces titanium powder, rather than ingots. The powder can be pressed and fused into near-net shape, reducing
the amount of final machining required.

helps strengthen blood clots. Normally
after an injury, platelets in the blood
begin to congregate at the wound and
form an initial barrier. Then a network
of specialized fibers—called fibrin—
start weaving themselves throughout
the clot to reinforce it. Both PolySTAT
and factor XIII strengthen clots by
binding fibrin strands together and
adding cross-links that reinforce the
latticework of the natural bandage.
