Scientists are searching for ways to destroy nuclear weapons in space—to make nuclear weapons powerless and no longer useful. This has become known as "Star Wars". (1) Supporters of the Star Wars defense system hope that this would not only protect a nation against an actual nuclear attack, but would be enough of a threat to keep a nuclear war from ever happening.
(2) Opponents of Star Wars are worried that a system might introduce nuclear weapons into outer space and might not completely protect the nation against attack. Some missiles might "leak through" the Star Wars defenses. Or the computers that run the system might not work properly. Such a defense system, they say, might also be used to attack others. And it might not stop the buildup of ground-based nuclear weapons.
Hopefully, a nuclear war will never begin. But, in such an event, could people really protect themselves Supporters of Star Wars believe

German researchers have (1) a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest.
In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart’s rhythm. Those most at risk are patients who have (4) suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions, such as that of pacemaker.
Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with an implanted defibrillator (7) of generating a six-channel electrocardiogram
