Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better than others
RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed ...

Some boreal forest species fail to recover even 100 years after clearcutting
Boreal forests are being clear-cut faster than some of their wildlife and plant species can recover, with a few failing to return even 100 years after harvesting, according to University of Alberta-led research.

Why Europe's rising plant diversity may signal habitat disruption, not ecological recovery
The number of plant species in many ecosystems in Europe has grown rather than shrunk over the last 100 years. However, this is not necessarily cause for celebration, as this local increase is primarily due to generalists ...

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 ...

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 ...

Heat is destroying Australia's underwater forests. Seaweed biobanks could help save them
Australia's Great Southern Reef is built not by coral but by seaweed. The seaweed forests on these rocky reefs stretch more than 8,000 kilometers (5,000 miles) around southern Australia.
