Mysterious ailment is wiping out starfish
UC Santa Cruz marine biologist Pete Raimondi is leading a team of scientists, laboratory technicians and geneticists to find the culprit. The Ochre star, which is common along the Pacific coast, has been dying in large numbers in recent months:
"Where it has hit, it has been pretty lethal. This is going on up and down the coast. It’s going to change what’s out there pretty fundamentally."

Controversial T. Rex Soft Tissue Find Finally Explained
by Stephanie Pappas
The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to new research, iron in the dinosaur’s body preserved the tissue before it could decay.
The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins — and possibly even DNA — can survive millennia. Schweitzer and her colleagues first raised this question in 2005, when they found the seemingly impossible: soft tissue preserved inside the leg of an adolescent T. rex unearthed in Montana.
"What we found was unusual, because it was still soft and still transparent and still flexible," Schweitzer told LiveScience…

The Secrets of Seahorse Success
by Sid Perkins
How does the seahorse, one of the slowest swimming fish in the sea, manage to capture its nimbler prey? In a word, stealth. Like most fish, seahorses nab their prey by slurping in the water surrounding their victims—a technique called suction feeding. But seahorses can effectively strike at prey only 1 millimeter or so in front of them, so they must approach within that distance (video) without disturbing the water so much that their quarry flees.
Now, lab tests show that fluid disturbances just ahead of the snout of the dwarf seahorse (Hippocampus zosterae) are only one-fifth as large as those elsewhere around its head, researchers report online today in Nature Communications. Thus, the fish was able to approach within striking range of its prey 84% of the time. Once within striking distance, the not-quite-galloping gourmand snaps its neck forward in less than a millisecond to successfully capture a meal 94% of the time.
