New, long-lasting flow battery could run for more than a decade with minimum upkeep

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.

The research, published in ACS Energy Letters, was led by Michael Aziz, the Gene and Tracy Sykes Professor of Materials and Energy Technologies and Roy Gordon, the Thomas Dudley Cabot Professor of Chemistry and Professor of Materials Science.

There’s a problem with the mummies at the University of Tarapacá’s archaeological museum in northern Chile.

They’re turning into a black oozy substance.

Harvard University’s School of Engineering and Applied Sciences says scientists have found that Chile’s famous 7,000-year-old Chinchorro mummies are being eaten by bacteria — and that climate change could be the culprit.
