Researchers propose a mechanism by which a protein produced in the placenta may trigger blood vessel growth and enlarge fat cells.

Stable, long-term cell lines will enable scientists to study everything from coral bleaching to biomineralization, knowledge that may help protect corals from ongoing climate change.

So-called mossy fiber synapses in the hippocampus can meter the amount of neurotransmitter they receive by sending glutamate against the usual direction of synaptic flow.

A study finds that slower-growing species are better able to adjust their growth to fit their hyphae through narrow passages.

Researchers use magnetic nanoparticles and liquid-handling robots in an effort to detect COVID-19 outbreaks early.

Researchers find different distributions of the immune cells in young, older, and diseased eyes.

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.

The leaky blood vessels and lung fluid build-up in some COVID-19 patients might be explained by the virus’s corruption of an inflammation safeguard.

A coronavirus has been commanding the headlines for months, but strains of influenza and paramyxovirus are extremely dangerous pathogens that could spark outbreaks.

The COVID-19 pandemic is sparking renewed efforts to study the underlying causes of this complex, debilitating disease, which might be triggered by the novel coronavirus.
