Hooking fish, not endangered turtles
A tuna fisherman has taken it upon himself to make the seas safer for sea turtles, animals that are threatened or endangered with extinction worldwide. He’s designed a new hook that he says will make bait unavailable to marine birds and turtles until long after it’s sunk well below the range where these animals venture to eat.

Infected bats can recover . . . with lots of help
Researchers reported new data today confirming that with enough coddling, many heavily infected bats can recover. The rub: These scientists also pointed out that there really aren’t sufficient resources to save more than a handful this way.

Eels point to suffocating Gulf floor
In June, scientists predicted that the Gulf of Mexico’s annual dead zone — a subsea region where the water contains too little oxygen to support life — might develop into the biggest ever. In fact, that didn’t happen. Owing to the fortuitous arrival of stormy weather, this year’s dead zone peaked at about 6,800 square miles, scientists reported on Aug. 1 — big but far from the record behemoth of 9,500 square miles that had been mentioned as distinctly possible.

Microbes may sky jump to new hosts
The role of microbes in cloud formation and precipitation may not be an accident of chemistry so much as an evolutionary adaptation by certain bacteria and other nonsentient beings, a scientist posited at the annual meeting of the American Society for Microbiology.

Methane from BP spill goes missing
Latest sampling suggests either that microbes have already devoured the most abundant hydrocarbon produced by the leak — or that researchers have simply lost track of it.

Bugged forests bad for climate
Trees savaged by pine beetles are slow to recover their ecological function as greenhouse gas sponges.
