Researchers found that thinning petunia cells’ cuticles caused them to slow production of volatile organic compounds.

Researchers develop a caspase inhibitor that only works after being irradiated with UV light, giving them control over apoptosis in human cells.

A new inhibitor gives researchers the ability to control programmed cell death in cultured human T cells.

This year’s most captivating illustrations tell stories from the micro scale—such as newborn neurons in the adult brain and bacteria in the infant gut—to the scale of entire ecosystems, including reintroduced predators and rising seas.

A recent study sheds light on a previously unknown mechanism for fending off the pathogen, and potentially other viruses as well.

In South Africa, the composition of droppings varies by species’ body sizes, and which animals are found where depends on vegetation density.

After weeks of training, the muscles of two macaques exhibited greater responses to stimulation of the reticulospinal tract in the brain stem than they had before, suggesting that strengthening the neural pathway is key to getting stronger. 

Understanding this complex and still largely enigmatic process will pave the way for researchers to control the development of new morphologies.

The gene BCO2 enables male and female members of some bird species to display dramatically different color patterns.
