Arya Biragyn, a molecular biologist at the National Institute on Aging, says he would have liked the team to have done more to show the microbiomes had actually changed in the older mice. Because the researchers checked for differences in the gut microbiome soon after the transplants, there’s no way to know whether the new microbes had truly moved in or were just passing through, he argues.
"But it takes a lot of work to make this blue, and so the other question becomes: What are the evolutionary reasons to make blue? What's the incentive?" Kupferschmidt said. "The fascinating thing when you dive into these animal worlds is always, who's the recipient of this message and can they see the blue?"
For example, while humans have three light-sensing receptor types in our eyes, birds have a fourth receptor type for sensing UV light. Feathers that appear blue to human eyes "actually reflect even more UV light than blue light," Kupferschmidt explained. By that reasoning, the birds that we call blue tits (Cyanistes caeruleus) "would probably call themselves 'UV tits,' because that's what they would mostly see," he said.
For today's lesson in Microbiology., we have the following:theres a guy who did just that. I'll post it tonight if i remember.
- Doing a fecal transplant from one human to another is an established procedure to try to get a better blend of bacteria into the gut. It would be guessed on my part that this is not very common, because it is new.
- Recent publications have documented a relationship, in humans, between the presence of certain bacteria in the gut, and brain function.
- Remember all that we eat is digested by the bacteria in the gut.
- Ingesting sugar, starches that convert to sugar, and alcohol have a definite affect on which bacteria are found growing in the gut; and not in a good way.
- A healthy diet, and the makeup of bacteria in the gut, are closely related.
- I saved the zinger for last. There are more bacteria, and bio related organisms in or on your body than human cells. Learn how to keep them happy and they will help keep you happy.
Using a tailor-made microscope sensitive to faint flashes of light, the team watched a culture of human cells containing a special light-sensitive material respond dynamically to changes in a magnetic field.
The change the researchers observed in the lab matched what would be expected if a quirky quantum effect was responsible for the illuminating reaction.
In 1975, a Max Planck Institute researcher named Klaus Schulten developed a theory on how magnetic fields could influence chemical reactions.
It involved something called a radical pair. A garden-variety radical is an electron in the outer shell of an atom that isn't partnered with a second electron.
Why is the color blue so rare in nature?And you pay for it. The blue granite countertops were an X, on a scale of A-Z, at the stone fabricator. They don’t give actual prices, basically just expensive or really fuckin expensive. Probably better off not knowing, remods are a leading cause of divorce.
