bacteria

MIT engineers engineered bacteria to produce hyperspectral signals that can be detected as far as 90 meters away. Their work could lead to the development of bacterial sensors for agricultural to monitor crop health, for example. Credits:Image: Jose-Luis Olivares, MIT; iStock

Engineered bacteria emit signals that can be spotted from a distance

The team analyzed genetic material from microbes in a one-of-a-kind archive of water samples collected over 20 years from Lake Mendota in Wisconsin.

Lake Bacteria Reveal a Stunning Seasonal Evolution Loop That Defies Expectations

Fruit flies are typically vulnerable to parasitic wasps, but some have acquired a bacterial gene that grants them resistance. This adult Drosophila melanogaster has two dark, melanin-coated cysts in its abdomen, marking the remains of wasp eggs that the fly successfully neutralized.

How researchers turn bacteria into cellulose-producing mini-factories

A (light green) bacterial cell detects a source of stress and becomes activated (dark green). It then produces alarmones (depicted as red triangles) and can transmit them to neighboring cells via cell-to-cell contact (black arrows). As the source of stress arrives, the percentage of activated cells increases, converting unstressed neighboring cells and triggering the stress response mechanism.
