Moths and Enemy Sonar
Luna Moth BE5506
"The camouflage and mimicry techniques that animals use to avoid becoming a meal aren't much use against a predator using echolocation. But a new study shows that moths can outsmart sonar with a flick of their long tails. Using high-speed infrared cameras and ultrasonic microphones, the researchers watched brown bats preying on moths. Luna moths with tails were 47 percent more likely to survive an attack than moths without tails. Bats targeted the tail during 55 percent of the interactions, suggesting the moths may lure bats to the tails to make an attack more survivable." - Science Daily, University of Florida, February 18, 2015, Moths shed light on how to fool enemy sonar View more images of luna moths
Flu season is here, but parents have a new condition to be worried about for their kids: Acute Flaccid Myelitis, or AFM. It has been making headlines as alarming numbers of children are being paralyzed in a pattern that resembles polio scares in the past.AFM has been in existence for a long time, but the recent rise in cases is what’s signaling danger. Polio was eradicated in the United States in 1979, however, at this point in time, there is no such future hope for AFM. This dreaded condition has several possible causes including viruses, environmental toxins, and genetic disorders. Symptoms often follow an infection and high fever. The suspected viruses that may cause AFM include poliovirus or non-polio enteroviruses, West Nile Virus and adenoviruses.

Symptoms parents should look out for include the sudden onset of drooping eyelids, difficulty mo…
Biologist and photographer Francesco Tomasinelli is willing to go where few others are: damp caves where the floors, walls and ceilings are crawling with living creatures.
Once there, he pauses to take beautiful and unusual photographs. He has captured giant cockroaches eating a dead bat, a snail slowly attacking a moth, and walls blanketed with crawling insects. Needless to say, the subjects of his images include endless numbers of spiders, scorpions, centipedes, and all manner of creatures that are the stuff of nightmares.

Tomasinelli says, “We are not used to considering small insects and specialized spiders that live in caves as noteworthy animals. But in recent years it has been discovered that these organisms can give us valuable indications to better understand the effects of climate change on ecosystems.” He was involved in a project called CAVELAB and has photographed in caves in Italy and Borneo.

The idea of bacteria creeping through your body might be less than appetizing. We often associate the presence of bacteria in our bodies (especially in our digestive system) with infections, viruses, and food poisonings. However, scientific findings have uncovered the fact that there are also many types of good bacteria that are essential to our health. This collection of good and bad bacteria within our bodies have also been discovered to be strikingly diverse from person to person.
The definition of the human microbiome is still somewhat ambiguous and disputed but is commonly known to be the vast ecosystem of microscopic organisms (microbes) living within us. According to the National Center for Biotechnology Information (NCBI), we consist of 10-100 trillion microbiota, also known as microbial cells. These cells hold genes that determine cell behavior.Stock Images and Stock Video of Microbes
