Many animal species add their eggs to the brood of other species to benefit from the latter’s brood care. This is called brood parasitism. Researchers recently studied brood parasitism in two ...

Today, 150 years after Darwin’s epochal “On the Origin of Species,” many questions about the molecular basis of evolution are still waiting for answers. How are signaling pathways changed by genes and ...

Molecular biologists have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism. They have shown that the genome of the nematode consists ...

One of the most interesting topics discussed in my Ornithology class was about the “con artists” found in nature… Brood parasitism occurs when a female bird (the parasite) lays her eggs in the nest of ...

HYDERABAD: A genomic study by CSIR-Centre for Cellular and Molecular Biology (CCMB) and Indian Institute of Science Education ...

The blood fluke may be the ultimate parasite. This ingenious flatworm comes of age inside a tiny snail host before entering its real host—humans—directly through the skin and burrowing into the ...

In the late 19th century, when scientists first discovered the single-celled creature called Nephromyces, they thought it was a parasitic fungus. They were wrong ...

Anglerfish mating is a familiar story: Boy meets girl, boy becomes attached to girl, their bodies and bloodstreams fuse as one, and the pair reproduces happily until the male fish dies. This ...

As the planet’s most expansive ecosystem, the deep sea can be a tough place to find a mate. Though, scientists say, some deep-sea anglerfishes evolved a unique method of reproduction that ensures that ...
