DAVID GREENE, HOST:

A gluttonous predator is power-eating its way through reefs from New York to Venezuela. It's the lionfish.

And although researchers are coming up with new ways to protect some reefs from the flamboyant maroon-striped fish, they have no hope of stopping its unparalleled invasion.

Lad Akins has scuba dived in the vibrant reefs of the Bahamas for many years. But when he returned a couple years ago, he saw almost no fish smaller than his hand.

In a case considered pivotal to the future of science and medicine, the justices of the U.S. Supreme Court seemed skeptical Monday about a claim that human genes can be patented.

Contending that genes can be patented are the biotech and pharmaceutical industries, which see patents as the keys to new scientific exploration. On the other side are doctors, patients and many scientists, who see gene patents as an attempt to monopolize and block future exploration in the new universe of genetics.

Is small-batch hard apple cider the next microbrew? It seems everybody and their brother is experimenting with ways to make the potent stuff profitable. Sales of domestically produced hard cider have more than tripled since 2007, according to beverage industry analysts — and that's not counting Europe, where it has held a steady popularity for centuries.

How wrong was Punxsutawney Phil when the groundhog said on Feb. 2 that we'd have an early spring?

The numbers are pretty grim: More than half of all 85-year-olds suffer some form of dementia.

But here's the good news: Brain researchers say there are ways to boost brain power and stave off problems in memory and thinking.

Same-sex marriage got huge headlines at the Supreme Court last month, but in the world of science and medicine, the case being argued on Monday is far more important. The lawsuit deals with a truly 21st century issue — whether human genes may be patented.

Communications between the Earth and Mars are on hiatus for several weeks, thanks to interference from the sun. That means NASA's orbiters and rovers that study Mars will be left to their own devices until radio signals can once again travel between the two planets.

Known as "solar conjunction," the problem arises when the orbit of planets places the sun directly between them.
