Toilets in the news (again). Researchers Dr. Liang, Dr. Ding, Dr. Wu, and Dr. Sun have concluded, after a meta-analysis of data from 4,915 papers published on the subject, that global warming can increase the incidence of infectious diarrhea (ID). ID can consist of dysentry, cholera, typhoid fever and paratyphoid fever, as well as foodborne infections. The general message to mankind here is that as global temperatures rise, we should prepare for more diarrhea (traces back to this paper from 2021).
Dinosaurs died maybe because they were on ‘shrooms. Dinosaurs died around 66 million years ago, around the time that the genus Psilocybe, or magic mushrooms evolved, according to genetic analyses. If dinosaurs died because of magic mushrooms, at least they died happy. (9 Jan)
This proves we can talk to aliens. Researchers from University of California at Davis sailed to the southeast coast of Alaska to talk to a humpback whale named Twain, in what they believe is the world’s first successful whale-human communication. But having a 20-minute conversation with a whale wasn’t the endgame for these researchers. What they really want to do is talk to aliens by interpreting signals from outer space by using whales for practice. (7 Mar)
They’re out there. Not having found aliens yet, frustrated astrophysicists from the University of Rochester have moved beyond looking for biological markers, and have begun looking for technological markers. They have decided that to accomplish this, they will look for the presence of oxygen, being convinced that it correlates with advanced technology. The thinking being: where there’s oxygen, there’s aliens; where there’s aliens, there’s fire; and where there’s fire, there’s someone setting that fire; and where someone is setting the fire, someone is using it to make something; and where there is something made, there is advanced technology. They are looking for a planet with an atmosphere of at least 18% oxygen, the same as that on Earth. The work is being partially funded by a grant from NASA. (2 Jan)
GMOs found in nature. It was found that under controlled conditions in the lab, that gene transfer could occur in 5% of zebrafish, provided they were near an electric eel that was discharging electricity at the time. Bodies of water are full of ambient DNA, known as environmental DNA (eDNA), which is what scientists have observed being transferred into the zebrafish. eDNA could come from plants, single-celled creatures or other animals. Scientists suspect that eels can contribute to biodiversity or even the creation of new species. (Dec 2023 1 2)
