Animal cells cannot produce 9 of the 20 amino acids they need to function. Some researchers are looking to change that.

The winding trail of environmental microplastics leads researchers to the human digestive ecosystem.

Bacteria cooperate to benefit the collective, but cheaters can rig the system. How is the balance maintained?

From spatial structuring to policing, cooperative bacteria have a wide toolkit to contain the spread of cheaters.

Microbiomes transplanted from women with anorexia nervosa into mice enhanced symptoms of the eating disorder, such as rapid weight loss and reduced appetite.

Researchers repurpose tiny bacterial injection systems to specifically inject a wide variety of proteins into human cells and living mice.

Urinary tract infections leave permanent epigenetic marks in the mouse bladder epithelium, reprogramming its response to subsequent infections, a study finds.

Aging cells with weakened gene regulation spuriously transcribe RNAs, but their impact on health and longevity still needs to be examined.

Political activist and Nobel winner Dorothy Crowfoot Hodgkin pioneered X-ray crystallography to discover the molecular structures of penicillin and insulin.

Modification on a high-resolution fluorescent microscopy technique allow researchers to track the precise movements of motor proteins. 

Self-contained synthetic E. coli resistant to viral infection could prove invaluable to the biotechnology industry by increasing product consistency and reducing safety concerns. 

The opportunistic pathogen Klebsiella aerogenes degrades estradiol and induces depressive-like behavior in mice, a study finds.

Regulatory T cells in the colon travel to muscles to promote wound healing in mice, raising questions about how antibiotics may impact injury recovery.
