...captive swim-with dolphins than does the Dominican Republic, Mexico or any of the world's other worst offenders. The only reason some American swim-with programs provide dolphins with better working conditions is that the U.S. is wealthier, not because it's the law. NAOMI A. ROSE MARINE MAMMAL SCIENTIST Humane Society of the U.S. Washington...
...second study, which examined the disappearance of large animals in Australia, sought to specify the time frame of the extinction rather than the cause. According to the study, every Australian land mammal, reptile and bird heavier than 100 kg and most of those weighing 45 to 100 kg died out 46,400 years ago. The study, which used optical dating to pinpoint the age of fossils from sites across Australia, narrowed the previously fuzzy timeframe of the extinction. But the new dates makes human influence a more likely factor because scientists believe humans arrived on the continent between...
Many tourists would be horrified at the thought. A growing number of them are getting a natural high by bonding with these seagoing mammals in aquatic parks both in and outside the U.S. In 18 national programs, visitors can pay up to $150 to hop into the pool for a half-hour "swim-with" the dolphins. These U.S. programs generally treat their featured attractions well: dolphins are no longer captured in the wild, and there are guidelines to limit the mammal's workday (no more than two hours) and office space (a sanctuary away from humans is required...
...born?if the event hasn't happened already, as some scientists speculate. The team that cloned Dolly waited until she was seven months old to announce her existence. Creating her took 277 tries, and right up until her birth, scientists around the world were saying that cloning a mammal from an adult cell was impossible. "There's a significant gap between what scientists are willing to talk about in public and their private aspirations," says British futurist Patrick Dixon. "The law of genetics is that the work is always significantly further ahead than the news. In the digital world, everything...
