A European-Asian collaboration of scientists have identified ten virulence genes of the tubercle bacillus. The inactivation of these genes lessens the pathogenic effects of the bacillus. This ...

Scientists discovered a parasitic ant queen that hacks colony odors to trigger queen murder, exposing a rare form of chemical manipulation.

Parasitism evolved at least 223 times, far more than the previous estimate of 60. It arose more times in certain phyla (e.g., arthropods, nematodes, flatworms, and mollusks) than in others. Today, ...

Megacopta cribraria (F.) (Hemiptera: Plataspidae) is a newly invasive, exotic pest of soybean (Glycine max [L.] Merr.; Fabales: Fabaceae) in the southeastern United States. In 2013, the exotic egg ...

Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate.

Species have strong indirect effects on others, and predicting these effects is a central challenge in ecology. Prey species sharing an enemy (predator or parasitoid) can be linked by apparent ...

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 ...

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 ...

Generals are famously always “studying how to fight the last war,” with the last war’s technology, while dismissing how the world and its tech have changed in the interim. This is true for dissidents, ...
