Researchers have discovered how to use cyanobacteria–commonly called blue-green algae–to continuously power a microprocessor for a span of more than six months. The system, which uses inexpensive and largely recyclable materials, contains a type of non-toxic photosynthetic algae called Synechocystis, per a statement. The research was published in the journal Energy & Environmental Science. "We were impressed by how consistently the system worked over a long period of time–we thought it might stop after a few weeks but it just kept going," says Paolo Bombelli, a researcher from the University of Cambridge's Department of Biochemistry and lead author of the paper. The scientists created an enclosure out of aluminum and clear plastic and put the bacteria inside it. The device, which is about the size of a AA battery, was placed on a windowsill in Bombelli's home during Covid-19 lockdown in 2021 and remained there from February to August. The bacteria powered an Arm Cortex M0+ processor–a microprocessor widely used in the network of appliances connected to the internet, also called the Internet of Things (IoT). The cyanobacteria produced energy even without light, perhaps because they process some of their food in the dark, which generates an electrical current. Several billion IoT devices already exist, and that number is expected to rise to one trillion by 2035. Powering all those devices would require 109,000 tons of lithium, which is three times more than what the world produced in 2017.

One of the world's most isolated aquatic mammals, Arctocephalus philippii, can tolerate high levels of cadmium, as well as other metallic pollutants, without suffering ill effects. A. philippii is the second smallest species of fur seal and lives only on the Juan Fernández archipelago and one or two nearby islands in the Pacific Ocean, hundreds of miles off the coast of Chile. By the 19th century, the species had disappeared and was believed to be extinct until, in the 1960s, a small colony was found in a cave on the island. Since then, the Juan Fernández seal, which has become a protected species, has slowly recovered and has a population of around 80,000. "We collected samples of their faeces and found they contained extremely high levels of cadmium and other elements such as mercury," said Constanza Toro-Valdivieso of Cambridge University's conservation research institute. "The discovery was very surprising," she said. "Cadmium is poisonous to mammals but somehow these seals were processing it and passing it through their digestive systems and seem to be suffering little harm in the process." High levels were found not only in its faeces but in the bones of seals that had died of natural causes. The researchers also found high levels of silicon in their bones, which may be offsetting the impact of cadmium, they suggest. "The discovery that these animals appear to tolerate high levels of cadmium in their bodies has important medical implications," said Toro-Valdivieso. "These animals have a lot to tell us."
