With 3D-Printed Bacteria, This Bionic Mushroom Turns Light Into Electricity

Posted on Categories Discover Magazine

The bionic mushroom created by the researchers. (Credit: American Chemical Society) “Power mushrooms” sounds like something out of Super Mario, but a lab in New Jersey has made them a reality. Hoping to create a new source of renewable energy (and to test out some ideas), a team at the Stevens Institute of Technology engineered a symbiotic relationship between the common button mushroom, some cyanobacteria and a few electrodes made of “graphene nanoribbons” (GNRs) &mdas ...read more

Flushed Pharmaceuticals Are Likely Drugging Stream Dwellers Like The Platypus

Bugs are consuming pharmaceutical drugs pumped into streams, which then end up in the systems of predators, like the platypus. (Credit: John Carnemolla/shutterstock) Humans don’t absorb 100 percent of the drugs we consume. The pharmaceuticals that our bodies don’t use are flushed out of our systems and flushed down into sewage systems, processed in water treatment plants, and finally dumped into streams and other waterways. But an alarming number of pharmaceutical compounds aren&rs ...read more

It’s always a bit stupefying to gaze at a femur pulled from the earth and think about it being on the inside of a living, breathing human very much like yourself. But that’s not what stood out to Erik Trinkaus, an anthropologist at Washington University who studies the bones of ancient humans. He had a pivotal realizati ...read more

Interstellar Visitor 'Oumuamua is Probably Not an Alien Solar Sail

An artist’s impression of the strange, interstellar object ‘Oumuamua. One new study suggests that the space rock could actually be an extraterrestrial light sail. (Credit: ESO/M. Kornmesser) ‘Oumuamua — a curious, cigar-shaped rock — was the first interstellar space rock ever discovered in our solar system, though scientists debate whether it should be classified as an asteroid or comet. Now, a new study suggests that the strange object could actually be an alien ...read more
