SCIENCE NEWS - TICKS #4

TICKS

Ticks can really get under your skin—literally. And in many parts of the country they spread illness, including Lyme disease and Rocky Mountain spotted fever. Add to that list a new scourge: Heartland virus, which doesn't respond to treatment.
This infection was described for the first time last year after two Missouri men were hospitalized with fever and headaches. No one was sure how the men contracted the disease. Now a study in theAmerican Journal of Tropical Medicine and Hygiene confirms that ticks were the transmitters. [Harry M. Savage et al., First Detection of Heartland Virus (Bunyaviridae: Phlebovirus) from Field Collected Arthropods]
Researchers tromped out to the two men's properties, and 10 more sites in the region, to set up tick traps. These included containers of dry ice, which emit carbon dioxide to attract ticks, and flannel bedding, which traps them. They also picked some ticks off of area dogs and horses.
All told, they collected more than 56,000 tick specimens. And they found the virus residing in lone star ticks—the most common in the region. About one in 500 of the arachnids carried the virus. Enough to make me check for ticks. And then check again.

SCIENCE NEWS - THRESHER SHARKS #3

THRESHER SHARKS

They’re called thresher sharks. But perhaps thrasher is more accurate. Because a population of these fearsome predators was spotted engaging in an unusual hunting strategy.
Forget jaws—try the other end. Researchers observed them slapping their long, scythe-like tails at high speeds through the water. These whaps stunned or killed several smaller fish with each strike. The observations were made off the coast of the Philippines.
Killer whales and dolphins also may use a similar tail-slapping strategy. But this is the first time the behavior has been seen in sharks.
Although the formidable, three-meter-long pelagic thresher shark seems able to catch food face-first, the ability to immobilize more than one fish at a time makes the method highly efficient. The findings are in the journal PLoS ONE. [Simon P. Oliver et al., Thrasher Sharks Use Tail-Slaps as a Hunting Strategy]
These sharks used both vertical and horizontal tail slaps to capture prey, which were stunned or killed either by direct impact or by a shockwave from the smack. More than a third of the vertical slaps resulted in a meal for the shark—better stats than when sharks chased prey head on. And that's no tall tale.
