Evidence in the bones reveals rickets in Roman times

Evidence in the bones reveals rickets in Roman times

Rickets is mostly seen as a 19th-century disease, but research has revealed that the Romans also had a big problem with getting enough vitamin D. Researchers from Historic England and McMaster University in Canada examined 2,787 skeletons from 18 cemeteries across the Roman empire and discovered that rickets was a widespread phenomenon 2,000 years ago.

The Cost of Plastic Convenience #NoPlasticJuly

The Cost of Plastic Convenience #NoPlasticJuly

July signifies the beginning of environmental campaigns heavily focused on the issues of plastic output.

A galaxy 11.3 billion light-years away appears filled with dark matter

A distant galaxy appears filled with dark matter. The outermost stars in the Cosmic Seagull, a galaxy 11.3 billion light-years away, race too fast to be propelled by the gravity of the galaxy’s gas and stars alone. Instead, they move as if urged on by an invisible force, indicating the hidden presence of dark matter, astrophysicist Verónica Motta of the University of Valparaíso in Chile and her colleagues report August 8 at arXiv.org.

A filter that turns saltwater into freshwater just got an upgrade

A filter that turns saltwater into freshwater just got an upgrade

Smoothing out the rough patches of a material widely used to filter saltwater could make producing freshwater more affordable, researchers report in the Aug. 17 Science. Desalination plants around the world typically strain salt out of seawater by pumping it through films made of polyamide — a synthetic polymer riddled with tiny pores that allow water molecules to squeeze through, but not sodium ions. But organic matter, along with some other waterborne particles like calcium sulfate, can accumulate in the…
