Joshua Cassidy of KQED highlights an MIT study about how cats use their tongues to drink. The researchers created a model that mimics how cats drink and determined that “house cats tend to lap water about four times a second while larger species of cats, like lions and tigers, lap slower as their body mass increases.”
Graduate student Eric Arndt discusses his research on the bombardier beetle’s ability to produce a boiling-hot stream of liquid on the PBS program SciTech Now. “Insects, as it turns out, are very good material scientists,” explains Arndt. “Just studying these fundamental systems has the possibility of opening up all kinds of doors in all kinds of industries.”
Sindya Bhanoo writes for The New York Times that MIT researchers have discovered how the bombardier beetle produces blasts of a hot, lethal toxin to fend off predators. “The beetle has a really complicated explosion system that’s all connected together,” explains Prof. Christine Ortiz.
MIT researchers have figured out how the bombardier beetle can fire off chemicals when threatened, writes Washington Post reporter Rachel Feltman. Feltman explains that the researchers used “high-speed x-ray imaging” to examine the beetle’s defense mechanisms in action.
By examining X-ray images, MIT researchers have uncovered how bombardier beetles are able to produce “machine-gun style” blasts of chemicals to fend off predators, reports Andy Coghlan for New Scientist. “The researchers were surprised to find that a passive mechanism generates the pulses,” Coghlan explains.
New MIT research offers a detailed look at how the bombardier beetle produces the scalding black liquid it expels as a defense mechanism, writes Brooks Hays for UPI. “The process operates almost like an assembly line of chambers and valves -- chemicals mixed, pressure builds, chemical released in jet-like spray through valve, relax and repeat.”
Researchers from MIT and Harvard have identified the optical features within a limpet’s shell that allow the mollusk to display blue stripes, reports Nidhi Subbaraman for BetaBoston. The findings could inspire developments in augmented reality screens.
