Schools of mollie fish “do the wave” to evade predators

We've all seen sports spectators performing "the wave," where people stand up then sit back down to simulate a wave moving through the stadium. Well, schools of mollies have been found to perform a similar action, in order to keep from being eaten.

Study finds that moth wingtips serve as bat-foiling “acoustic decoys”

Because both bats and moths are nocturnal, bats use echolocation to zero in on the insects when hunting them in the dark. A new study, however, suggests that some moths have evolved special wingtips to avoid becoming a meal.

Blood pressure “barometer” cells discovered in the kidney

Researchers have discovered a population of natural barometers that monitor and maintain our blood pressure. The cellular sensors have for decades been presumed to be located in a certain type of cell in the kidney, but have only now been detected.

Tomato study suggests fruits can warn mother plants of pest attacks

Because fruits just dangle from the main plant before ultimately falling off, one might think that they are unable to communicate with that plant. According to new research, however, tomato fruits are able to transmit alerts to their mother plant.

Alien-like extendable secondary jaws allow moray eels to hunt on land

Most fish utilize a mouthful of water to swallow their prey. According to a new study, however, moray eels are unique in not doing so, allowing them to feed while out of the water … with some help from a second set of jaws in their throat.
