Gleanings of the Week Ending June 17, 2023
/The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.
Humans taking a toll on Yellowstone wildlife - In recent days two black bears have been killed by motorists, an elk and a bison were also hit by vehicles, a newborn elk calf was picked up by motorists concerned for its fate, and a bison calf had to be put down after a visitor tried to help it out of the Lamar River so it could catch up with its mother. I remember that the park had good signage trying to educate people….seems that it isn’t as effective as I assumed it would be.
See the Rare Albino Echidna Spotted in Australia – It’s been named (Raffie) and photographed…evidently still in the wild! A piece of trivia from the article: a baby echidna is a puggle.
Tune in to the Great Salt Lake kestrel cam – Take a look…they hatched on May 17th…and they are growing up fast.
Scientists target human stomach cells for diabetes therapy – Still very much in research phase…but it would certainly improve the lives of a lot of people if it can be developed into a treatment!
This New Device Generates Electricity from Thin Air – Evidently the device can be made from any material that can be punctured with ultra-small holes. Too good to be true….or competitive with established clean energy sources like wind and solar?
Super low-cost smartphone attachment brings blood pressure monitoring to your fingertips – A clip that fits over the phone’s camera and flash…an app. It costs about 80 cents to make but the cost could be as low at 10 cents when manufactured at scale. Evidently it does not need to be calibrated either! I wonder if cuffs will become a thing of the past very quickly!
What we know about the health risks of ultra-processed foods – Research teasing out what exactly about ultra-processed food is bad. I’ve been trying to reduce ultra-processed food…so have been following the advice in this article for at about a year: if you're considering eating a packaged food, read the ingredient list…If you really have no idea what some of those ingredients are, it probably went too far.
You can make carbon dioxide filters with a 3D printer – Printing a hydrogel material that holds carbonic anhydrase (an enzyme that turns carbon dioxide and water into bicarbonate).
Nepal Won’t Move the Mount Everest Base Camp for Now, Despite Risks – Everest’s highest glacier has lost half its mass since the 1990s because of higher temperatures. It may only be a few years before the camp needs to move.
Colombia’s ‘cocaine hippo’ population is even bigger than scientists thought – Wild descendants of the hippos introduced in Columbia by Pablo Escobar….considered the largest invasive animal in the world. There are probably 181-215 of them in Columbia. Several strategies are being tried: contraception administered via dart, castration, exporting the animal to sanctuaries abroad. Culling appears to be the only strategy that can save the biodiversity of Columbia.
