For humans, the superbug MRSA, or methicillin-resistant staphylococcus aureus, is one of the most terrifying creatures that share our Earth.

A bacterium that is resistant to most antibiotics, it is estimated to have contributed to the death of 5,000 Americans in 2013. Many more develop invasive infections that can lead to complications like losing a limb.

Public health officials have been hunting for an effective treatment for decades but have mostly run into dead-ends. Now, a study published in Nature Communications raises the possibility that a promising new weapon for MRSA may have been right under our noses: tamoxifen.
