Who knew bacteria could trap light without chlorophyll?


It’s not just that we learn new things every day but some of the new things would change our view of things in ways no one predicted:

For years, scientists have thought that microorganisms that use chlorophyll capture the majority of solar energy in the ocean. In study published this week (August 7) in Science Advances, researchers show that bacteria with proteorhodopsins—proteins that capture light with a pigment called retinal—play a major role in converting light to energy, especially in parts of the ocean where nutrients are scarce.

“Chlorophyll is a big deal in the ocean, and now we’re showing that this other pigment is just as important,” says University of Southern California biologist Laura Gómez-Consarnau, a coauthor of the new study.

We are “trained,” if you like, to expect certain discoveries (dark matter, for example). Then we learn something significant that really surprises us and allows for new thinking about, for example, ecology.

Before you go: DNA uses “climbers’ ropes method” to keep tangles at bay It all just swished into place among unthinking cells billions of yours ago. Otherwise we wouldn’t be here. Go tell it on the mountain.

DNA as a master of resource recycling

The amazing energy efficiency of cells: A science writer compares the cell to human inventions and finds that it is indeed amazingly energy-efficient.

In addition to DNA, our cells have an instruction language written in sugar Of course it all just tumbled into existence and “natural selection” somehow organized everything. As if.

Cells find optimal solutions. Not just good ones.

Researchers build “public library” to help understand photosynthesis

Wait. “The part of the plant responsible for photosynthesis is like a complex machine made up of many parts, … ” And machines just happen all by themselves, right? There is no information load to account for; it just evolved by natural selection acting on random mutation the way your Android did!

In Nature: Cells have “secret conversations” We say this a lot: That’s a lot of information to have simply come into being by natural selection acting on random mutation (Darwinism). It’s getting not only ridiculous but obviously ridiculous.

Researchers: Helpful gut microbes send messages to their hosts If the strategy is clearly identified, they should look for non-helpful microbes that have found a way to copy it (horizontal gene transfer?)

Cells and proteins use sugars to talk to one another Cells are like Neanderthal man. They get smarter every time we run into them. And just think, it all just tumbled into existence by natural selection acting on random mutations (Darwinism) too…

Researchers: First animal cell was not simple; it could “transdifferentiate” From the paper: “… these analyses offer no support for the homology of sponge choanocytes and choanoflagellates, nor for the view that the first multicellular animals were simple balls of cells with limited capacity to differentiate.”
