Scientists transferred light-harvesting proteins into yeast for the first time, shining a light on the past lives of eukaryotic cells.

Vaccination has beaten back infections for more than a century. Now, it may be the next big step in battling cancer.

Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.

Modifying mouse memories; mitochondria-disrupting antibiotics; horizontal gene transfer across animals; T cells target dengue; optogenetics without the genetics

The approach could help test hypotheses about how atypical function of the brain’s immune cells contributes to autism.

Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

With human research trials resulting in dozens of successful deliveries in the US and abroad, doctors move toward offering the surgery clinically, while working to learn all they can about uterine and transplant biology from the still-rare procedure.

Sequences for the model organism and two of its kin reveal how these plants got their oversized genomes.

The immune system is often likened to the military.
