Bacteria swim with whole body, not just propellers
When it comes to swimming, the bodies of some bacteria are more than just dead weight, according to new research from Brown University.
Australian brush-turkey eggs inspire ideas for germ-resistant coatings
(Phys.org) —Rather than sit on its eggs to incubate them, the Australian brush-turkey buries them in rotting vegetation. While bacterial decomposition heats the eggs, it doesn't infect them. University ...
Pigment or bacteria? Researchers re-examine the idea of 'color' in fossil feathers
Paleontologists studying fossilized feathers have proposed that the shapes of certain microscopic structures inside the feathers can tell us the color of ancient birds. But new research from North Carolina State University ...
Researchers' smartphone 'microscope' can detect a single virus, nanoparticles
(Phys.org) —Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.
Researchers create three-dimensional model of bacterium
Certain bacteria can build such complex membrane structures that, in terms of complexity and dynamics, look like eukaryotes, i.e., organisms with a distinct membrane-bound nucleus. Scientists from Heidelberg University and ...
3-D molecular syringes: Scientists solve structure of infection tool used by Yersinia bacterium
Abdominal pain, fever, diarrhoea—these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called inject ...
Data from end of the last ice age illuminate the precarious nature of global ocean chemistry
The ocean the Titanic sailed through just over 100 years ago was very different from the one we swim in today. Global warming is increasing ocean temperatures and harming marine food webs. Nitrogen run-off ...
Fetch, boy! Study shows homes with dogs have more types of bacteria
New research from North Carolina State University and the University of Colorado shows that households with dogs are home to more types of bacteria – including bacteria that are rarely found in households ...
Feast clue to smell of ancient Earth
Tiny 1,900 million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like.
Researchers find cicada wing structure able to kill bacteria on contact (w/ video)
Earthquakes, glue and grappling hooks: Scientists dissect the movement of bacteria
(Phys.org)—A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has discovered that microscopic bacteria have a lot in common with earthquakes—when it comes ...
Harnessing plant-invading fungi for fuel
(Phys.org)—As gas prices rise around the world, researchers are seeking a potential solution from endophytic fungi—fungi that live inside plants.
New biochip technology uses tiny whirlpools to corral microbes
Researchers have demonstrated a new technology that combines a laser and electric fields to create tiny centrifuge-like whirlpools to separate particles and microbes by size, a potential lab-on-a-chip system ...
Amoeba feast on backpacks
(Phys.org)—The amoeba Acanthamoeba cunningly traps motile bacteria, collecting them in a rucksack before devouring the whole backpack. This behaviour of the single-cell organisms is unique.
