Take a look inside the bladder of an aquatic bladderwort plant. You can see the single-celled algae, called desmids, that it has consumed. They will be digested to provide the plant with needed ...

This landscape of blue, red, and gold is a cross section through a developing human bone. Human bones have a hard outer layer made of condensed bone and a softer inner core of spongy bone. This ...

These spiked yellow pollen grains are still contained within the anther of this aster (a daisy-like flower) where they were produced. However, once they are released, they can travel great distances ...

This is a lonely little pollen grain, sitting on the petal of a thale-cress plant. Although it is solitary now, it was released into the air along with thousands of other pollen grains. This is a ...

This conglomeration of shapes and colors is a cluster of sporangia – known as a sorus – of a fern. A sporangium is where a fern produces the spores that allow it to reproduce. Get a closer view of the ...

Measure and monitor HHMI’s institutional greenhouse gas emissions at the two campuses we operate and look for strategies on greenhouse gas reduction at both campuses. Harness the tremendous community ...

Neurons communicate using electricity and chemistry. Most neurons are composed of three main parts, each of which plays a special role in this communication. First is the cell body, which is the ...

While this might look like an impressionistic painting of a lush bouquet, it’s actually a microscopic image of mold growing in a culture dish. In fact, if you’ve ever wondered what the fuzz on those ...
