About 35 years ago, Dr. Raymond Damadian invented a technology that transformed medical science. MRI, or magnetic resonance imaging, has been widely used in medical research ever since. Researchers over the years have employed it in a variety of ways, including using it to uncover cancers early enough for effective treatment.

A recent narrative-style article in Smithsonian magazine highlighted research in the largely unexplored Congo River in central Africa, where researchers have identified new fish species. The researchers preliminarily confirmed that strong currents in deep waters had isolated the breeding populations of certain fishes, including the bottom-feeding elephant fish.

Sea urchins are spiny marine animals. Some of them like to hide in holes that they dig out of limestone in the ocean floor, using teeth that are ground down and yet remain sharp. What makes these teeth so special that they can drill through rock and not go blunt?

Mankind’s attempts at bioengineering have yet to match the precision of some techniques already found in nature: cloning, tissue culturing, and gene therapy. Recent studies have explored how these processes operate in amoebas, aphids, and parasitic wasps, respectively.

Certain aphids manipulate plant tissues to form a hollow gall in which they then reside. But aphids will also help heal plant tissue that they’ve damaged. This behavior serves as a vital self-defense mechanism, because when the gall’s walls are eaten by caterpillars, the tender aphids inside become easy prey for other insect predators.
