Researchers at an Ohio State University greenhouse are awaiting a rare second bloom by a rainforest plant known as a corpse flower because of its unpleasant odor.

The university says the nearly 6-foot titan arum is expected to open this week, releasing another round of its rotting-flesh smell a little more than two years after it first flowered.

A second corpse flower opened briefly at the greenhouse last May.

A university spokeswoman tells The Columbus Dispatch (http://bit.ly/15FLGSU ) cultivators are lucky to have three blooms in three years. Each brief bloom attracts visitors hoping to catch a glimpse or a whiff of it.

The plant expected to bloom soon is nicknamed Woody, after Buckeyes football coach Woody Hayes.

Red tide algae bloom causing record number of Manatee deaths in Florida

A deadly algae bloom is causing a record number of manatee deaths in Florida, state biologists said.

A red tide bloom has been killing ten or more manatees a day and the deadly algae bloom shows no sign of letting up any time soon, the Tampa Bay Times reported on Friday.

"This is probably going to be the worst die-off in history," said Martine DeWit, a veterinarian who oversees the state's marine mammal pathology laboratory.

The record for manatees killed by red tide was set in 1996 with 151 killed by a toxin in the algae bloom. As of Friday, the number killed this year hit 149, and the number could surpass the current record by the end of the weekend.

DeWit said the toxins in the bloom likely settled onto the sea grass that manatee eat, causing them to become paralyzed and eventually drown. The grass beds will also likely retain their poisonous coating for another two months.

Nearly a dozen manatees have been rescued and are being treated at the Lowry Park Zoo in Tampa.

Red tide turns the water into a rust color, releasing large amounts of toxins. The current bloom affects 70 miles of the southwest Florida coast, from Sarasota through the middle of Lee County.

Estimates show there are between 4,000-5,000 manatees in Florida, and less than half of them are found in southwest Florida, according to the Tampa Bay Times report. Virtually all of the manatees killed by the red tide have turned up in the center of that stretch.
