In a completely unrelated news story, another expensive artwork has been accidentally broken in a gallery. Mercifully, nothing of value has been lost:
https://www.theguardian.com/artanddesign/2023/feb/19/art-fair-visitor-breaks-42000-dollar-jeff-koons-balloon-dog-sculpture
If you ever wanted confirmation of the ridiculousness of the contemporary art world and how much these objects are actually worth, this quote sums it up:
Quote: | Sharing an old photo taken with Koons on his Instagram account on Saturday, [art collector] Gamson wrote that the mishap was “one of the most crazy things I’ve ever seen”. “Anyway, I tried to purchase the broken sculpture. It has a really cool story,” he added. |

Good descision to dis-endorse him, as I stated earlier doing that is a reflection of his character, which is not what you want in a politician. Some of the faux angst in the article though is a bit OTT. If he was sharing nude photos of her that she had reason to believe were private, then fair enough but as noted these were photos in the public domain, that she posed for, was paid for, and published in a mainstream mens magazine at the time. _________________ Every dead body on Mt Everest was once a highly motivated person, so maybe just calm the **** down. |

As far as I know, No. Simply drawing attention to the fact that someone posed nude for a magazine isn't a crime. But doing it to try to drag their character down in order to beat them in a popularity contest is poor darts and doesn't reflect well on his character IMHO. _________________ Every dead body on Mt Everest was once a highly motivated person, so maybe just calm the **** down. |

I can't imagine how I'm going to be doing what I do at age 67. The wear & tear on a tradies body after just 40 years is bad enough.
No mini excavators until I was in my mid 20's from memory. If you couldn't get access for a backhoe, it was hand dig.
I reckon I've moved enough dirt with a shovel to half fill Sydney harbour. _________________ Don't count the days, make the days count. |

It certainly is, but at least the greens know that the damage she can do to them is now somewhat limited. _________________ kill for collingwood! |

The Bikie wasn't Dustin Martin's Dad, it may have been an uncle, but not his Dad.
Regardless, now she gets to run around shooting her mouth off, generally accountable to no one for the next 5 years while getting paid as a Senator. _________________ Every dead body on Mt Everest was once a highly motivated person, so maybe just calm the **** down. |

Newly discovered enzyme that turns air into electricity, providing a new clean source of energy
Quote: | Australian scientists have discovered an enzyme that converts air into energy. The finding, published today in the journal Nature, reveals that this enzyme uses the low amounts of the hydrogen in the atmosphere to create an electrical current. This finding opens the way to create devices that literally make energy from thin air.
The research team, led by Dr. Rhys Grinter, Ph.D. student Ashleigh Kropp, and Professor Chris Greening from the Monash University Biomedicine Discovery Institute in Melbourne, Australia, produced and analyzed a hydrogen-consuming enzyme from a common soil bacterium.
Recent work by the team has shown that many bacteria use hydrogen from the atmosphere as an energy source in nutrient-poor environments. "We've known for some time that bacteria can use the trace hydrogen in the air as a source of energy to help them grow and survive, including in Antarctic soils, volcanic craters, and the deep ocean" Professor Greening said. "But we didn't know how they did this, until now."
In this Nature paper, the researchers extracted the enzyme responsible for using atmospheric hydrogen from a bacterium called Mycobacterium smegmatis. They showed that this enzyme, called Huc, turns hydrogen gas into an electrical current. Dr. Grinter notes, "Huc is extraordinarily efficient. Unlike all other known enzymes and chemical catalysts, it even consumes hydrogen below atmospheric levels—as little as 0.00005% of the air we breathe."
The researchers used several cutting-edge methods to reveal the molecular blueprint of atmospheric hydrogen oxidation. They used advanced microscopy (cryo-EM) to determine its atomic structure and electrical pathways, pushing boundaries to produce the most resolved enzyme structure reported by this method to date. They also used a technique called electrochemistry to demonstrate the purified enzyme creates electricity at minute hydrogen concentrations.
Laboratory work performed by Kropp shows that it is possible to store purified Huc for long periods. "It is astonishingly stable. It is possible to freeze the enzyme or heat it to 80 degrees celsius, and it retains its power to generate energy," Kropp said. "This reflects that this enzyme helps bacteria to survive in the most extreme environments. "
Huc is a "natural battery" that produces a sustained electrical current from air or added hydrogen. While this research is at an early stage, the discovery of Huc has considerable potential to develop small air-powered devices, for example as an alternative to solar-powered devices.
The bacteria that produce enzymes like Huc are common and can be grown in large quantities, meaning we have access to a sustainable source of the enzyme. Dr. Grinter says that a key objective for future work is to scale up Huc production. "Once we produce Huc in sufficient quantities, the sky is quite literally the limit for using it to produce clean energy."

I read that yesterday, also saw it on the news. Very interesting breakthrough. Early stages they'd be looking at small devices like a phone, smartwatch or hearing aids. Don't think it's going to be powering our homes any time soon though. _________________ Every dead body on Mt Everest was once a highly motivated person, so maybe just calm the **** down. |

And again, a female teacher having sex with a male student get off imprisonment.
It's not as if the industry can't find female teachers. They are everywhere, so why are these predatory females protected? |
