Theorists show how random processes cancel out to ensure microbial health — ScienceDaily

Fat bacteria? Skinny bacteria? From our perspective on high, they all seem to be about the same size. In fact, they are.

Precisely why has been an open question, according to Rice University chemist Anatoly Kolomeisky, who now has a theory.

A primal mechanism in bacteria that keeps them in their personal Goldilocks zones — that is, just right — appears to depend on two random means of regulation, growth and division, that cancel each other out. The same mechanism may give researchers a new perspective on disease, including cancer.

The “minimal model” by Kolomeisky, Rice postdoctoral researcher and lead author Hamid Teimouri and Rupsha Mukherjee, a former research assistant at Rice now at the Indian Institute of Technology Gandhinagar, appears in the American Chemical Society’s Journal of Physical Chemistry Letters.

“Everywhere we see bacteria, they more or less have the same sizes and shapes,” Kolomeisky said. “It’s the same for the cells in our tissues. This is a signature of homeostasis, where a system tries to have physiological parameters that are almost the same, like body temperature or our blood pressure or the sugar level in our blood.

“Nature likes to have these parameters in a very narrow range so that living systems can work the most efficiently,” he said. “Deviations from these parameters are a signature of disease.”

Bacteria are models of homeostasis, sticking to a narrow distribution of sizes and shape. “But the explanations we have so far are not good,” Kolomeisky said. “As we know, science does not like magic. But something like magic — thresholds — is proposed to explain it.”

For bacteria, he said, there is no threshold. “Essentially, there’s no need for one,” he said. “There are a lot of underlying biochemical processes, but they can be roughly divided into two stochastic

Babies’ random choices become their preferences — ScienceDaily

When a baby reaches for one stuffed animal in a room filled with others just like it, that seemingly random choice is very bad news for those unpicked toys: the baby has likely just decided she doesn’t like what she didn’t choose.

Though researchers have long known that adults build unconscious biases over a lifetime of making choices between things that are essentially the same, the new Johns Hopkins University finding that even babies engage in this phenomenon demonstrates that this way of justifying choice is intuitive and somehow fundamental to the human experience.

“The act of making a choice changes how we feel about our options,” said co-author Alex Silver, a former Johns Hopkins undergraduate who’s now a graduate student in cognitive psychology at the University of Pittsburgh. “Even infants who are really just at the start of making choices for themselves have this bias.”

The findings are published today in the journal Psychological Science.

People assume they choose things that they like. But research suggests that’s sometimes backwards: We like things because we choose them. And, we dislike things that we don’t choose.

“I chose this, so I must like it. I didn’t choose this other thing, so it must not be so good. Adults make these inferences unconsciously,” said co-author Lisa Feigenson, a Johns Hopkins cognitive scientist specializing in child development. “We justify our choice after the fact.”

This makes sense for adults in a consumer culture who must make arbitrary choices every day, between everything from toothpaste brands to makes of cars to styles of jeans. The question, for Feigenson and Silver, was when exactly people start doing this. So they turned to babies, who don’t get many choices so, as Feigenson puts it, are “a perfect window into the origin of this tendency.”
