‘Trained Immunity’ Offers Hope in Fight Against Coronavirus
A novel form of immunological memory that was mostly ignored for a century extends the benefits of vaccines. It could be of help in ending the COVID-19 pandemic.
How Two Became One: Origins of a Mysterious Symbiosis Found
Carpenter ants need endosymbiotic bacteria to guide the early development of their embryos. New work has reconstructed how this deep partnership evolved.
By Losing Genes, Life Often Evolved More Complexity
Recent major surveys show that reductions in genomic complexity — including the loss of key genes — have successfully shaped the evolution of life throughout history.
Can Vaccines for Wildlife Prevent Human Pandemics?
Studies suggest that self-disseminating vaccines could prevent the "spillover" of animal viruses into humans as pandemic diseases.
Math of the Penguins
Emperor penguins display rigorously geometric spacing and mathematical efficiency when they huddle together for warmth, which may reveal secrets to their overall health.
‘Zombie’ Microbes Redefine Life’s Energy Limits
A new model shows that the denizens of a vast, ancient biome beneath the seafloor use barely enough energy to stay alive — and broadens understanding of what life can look like.
Mitochondria May Hold Keys to Anxiety and Mental Health
Research hints that the energy-generating organelles of cells may play a surprisingly pivotal role in mediating anxiety and depression.
COVID-19 Is Raging. How Safe Is Your Backyard Party?
Awash in coronavirus data, misinformation and tremendous uncertainty, we need to put our risk analysis skills to the ultimate test.
Extra DNA May Make Unlikely Hybrid Fish Possible
