When mitochondria grow abnormally long, leaked RNA may activate anti-tumor immune responses
Researchers from the University of Osaka have demonstrated that mitochondrial hyperfusion, when induced by low levels of DRP1 or cellular stress, activates an immune response through the RIG-I–MAVS pathway. Dependent on the ...

Disabling SagA enzyme in VREfm infections makes drug-resistant bacteria vulnerable to vancomycin
Antibiotic resistance is one of the most urgent threats to global health, linked to an estimated 4.7 million deaths worldwide in 2019 alone. As more bacteria evolve to evade even last-resort drugs, the supply of effective ...

Spiders benefit from seemingly monotonous forests
In ecology, the principle holds that the more diverse and heterogeneous a habitat is, the more different species it supports. To promote species diversity in forests, clearings are therefore created for nature conservation ...

Giraffes combine quantities similarly to addition
In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition ...

This tiny organism contracts 200 times faster than we can blink—here's how
A tiny, aquatic, single-celled organism can contract to one-quarter of its body length in less than 5 milliseconds—hundreds of times faster than a human can blink. Researchers have discovered that the organism, Spirostomum ...

Toward experiment-guided AlphaFold: Researchers overcome AI tool's single-conformation limitation
The AI-based program AlphaFold predicts a protein's 3D structure with remarkable accuracy. However, it tends to reduce heterogeneous structures to a single dominant conformation, or shape, and overlooks experimental conditions ...

Childbirth is not uniquely difficult to humans
The tight fit of a baby's head through a mother's birth canal, which causes great difficulty in childbirth, is not unique to humans, as previously understood. Instead, some small-bodied primate babies have heads almost twice ...
