Altruistic Aphids, an Evolutionary Anomaly

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.


A New Technique for Pluripotent Stem Cells

Stem cell treatments have proven successful for many diseases, and there is great promise that new treatments will emerge to combat even more maladies. These successful treatments involve inserting correctly functioning stem cells into tissues where native mutated cells have caused disease.


Stewardship and Coconut-based Car Parts

Coconut husks, made of tough fibers, are abundant in tropical regions. Coconut farmers have most often discarded the husks, but science is finding creative ways to use them.


Insect Designed with a Spring in Its Step

Scientists are discovering engineering details of the biological structures that enable some animals to jump exceedingly far for their sizes. Froghoppers are insects that can jump 100 times their body length, and it turns out that sheer muscular strength is not nearly sufficient to account for this feat.


Biomineralization: An Engineering Masterpiece

Computerized tomography (CT) scans use computing power to compile two-dimensional X-ray images into a three-dimensional view, and researchers are optimistic that a new form of high-resolution CT scanning at the molecular level will give “scientists precious new information about how Mother Nature forms shells, bones, and other hard structures.”1 They hope to learn how to mimic the st
