Sentences with phrase «bacterial flagella»

When a microrobot is exposed to an external magnetic field — the offboard power source, given the difficulty in shrinking batteries to the size of bacteria — it begins to spin and move in a manner similar to bacterial flagella, courtesy of the iron oxide debris.

Nature had rotating axles billions of years ago, in the shape of bacterial flagella.

This rules out reciprocal motion — such as the way a fish uses their fins — so the microswimmers must rely on nonreciprocal motion similar to that of bacterial flagella, in which rotational motion is converted to translational motion.

Steven M. Block and his colleagues at the Rowland Institute in Cambridge, Mass., and at Harvard University have studied the mechanical properties of bacterial flagella.

«How nature engineered the original rotary motor: Study finds tether protein that measures bacterial flagella, holds cells together.»

For he spoke long before William Dembski began stringing out his texts with all those ones and zeros, and long before Michael Behe began instructing the lay public in the intricacies of bacterial flagella.

Please rationally explain why the Earth is the exact distance it must be from the sun to support life, why the moon is the exact distance from the Earth to sustain life, why the bacterial flagella is so genius, why the energy in a universe «moving toward order» is a finite, why we all have a moral intuition and why «relativism» is self - destructive, how something scientifically came from virtually nothing, why love is self - sacrificing, why procreation is enjoyable instead of painful, why man is eternally unsatisfied.

The proteins of the TTSS are directly ho.mologous to the proteins in the basal portion of the bacterial flagellum — making it a fully useful and functional pre-cursor to the flagellum, though performing a different function.

In the case of teh bacterial flagellum, removal of some of the «well matched parts» turns it into a type III secretory system which allows gram negative bacteria to translocate proteins directly into the cytoplasm of a host cell.

The book «Darwin's Black Box» argues that organisms like cilium, bacterial flagellum, animal cells, and antibodies are irreducibly complex.

This argument claims, for example, that the bacterial flagellum can not evolve from lower parts.

For example in the case of the bacterial flagellum, removal of a part may prevent it from acting as a rotary motor.

The argument against neo-Darwinism begins from the undoubted observation that many features of living beings, like the bacterial flagellum or the human eye, are the result of not one genetic mutation but of a large number of such mutations.

Whether a stone or an electron being attracted to a proton is intrinsically less wonderful than the eye or the bacterial flagellum is less clear.

But they argue that certain features of living things — the eye, for instance, or the bacterial flagellum — are irreducibly complex and could not have developed gradually by trial and error.

The bacterial flagellum is one of nature's smallest motors, rotating at up to 60,000 revolutions per minute.

Chapman: Yeah, and that's a good piece of work and what it did for me — to go on to continue that thought about the way in which it was an education — is what I saw was that it was possible for a complicated scientific subject to be discussed in front of a lay audience, not be patronizing to the lay audience, get across a lot of information and excite people because the local people were meeting outside the court and they were saying, «Well did you hear the things about the bacterial flagellum?»

It would waste (assuming the goal is not satire) too much space to put research articles in publications proving the moon is made of cheese (it's got craters, Swiss cheese has holes, by Glen Beck style logic: ergo...) or that the moon landings were faked or that the Earth is flat, or that purified water can do magic, or that you can get jewelry by staring at it through a shop window, or that a bacterial flagellum could not have evolved, — you know, common sense stuff like that...

Not exact matches

As a first line of defense against bacterial pathogens, plant cells recognize and respond to tiny bacterial molecules, such as pieces of flagellin that slough off the whip - like flagella that help the bacteria move.
