This is an 3D image of conidiophores of the filamentous fungus Neurospora crassa. Conidiophores are hyphae which differentiate to produce asexual structures named spores or conidia. The image taken using a confocal microscope shows conidiophores stained with a fluorophore which stains components... Read More
Hollywood has amplified the idea of a zombie apocalypse for a long time, and the stories have grown increasingly popular in pop culture, particularly due to TV shows like ‘The Walking Dead‘ and movies like ‘World War Z.’
However, when you take science fiction out of the equation and add real-... Read More
Growing cells – in a laboratory in space or on earth – forms a fundamental basis of modern microbiology, supporting everything from culturing microbes to novel drug design and growing human tissues for use in research and development. The problem is that cells grown on a 2D Petri dish do not ... Read More
A UCLA-led team of researchers has found evidence that photosensitizing a virus's membrane covering can inhibit its ability to enter cells and potentially lead to the development of stronger, cheaper medications to fight a host of tough viruses.
The UCLA AIDS Institute study, published in th... Read More
Germaphobes, maybe you're on to something.
Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More
A new class of molecules called acyldepsipeptides—ADEPs—may provide a new way to attack bacteria that have developed resistance to antibiotics.
Researchers have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemica... Read More
How long does it take to become a microbiologist?
I'd never heard of magnetotactic bacteria before and thought perhaps you guys might find this interesting. Not sure if you've mentioned these on TWIM before,... Read More
A false-coloured scanning electron microscope image of an African trypanosome, the parasite which causes sleeping sickness. Read More
Serratia marcesens is a Gram-negative, rod-shaped bacterium that is commonly found in soil, water, on plants and in animals and thrives in damp conditions. This organism is well known for its production of the blood red pigment, prodigiosin. Production of prodigiosin can be influenced by several... Read More
In this paper we describe the perspective of following the achievements in medicine, where gut microbiome transplants are proving to be a powerful method to overcome several gastrointestinal disorders and many other physiological problems, to possible solve diseases in plants. There is strong si... Read More
Streak plate isolation of Enterobacter aerogenes grown on MacConkey agar for 24 hours at 37 degree's. Colonies grow pink due to fermentation of lactose. Read More
This episode: Defective phages in bacterial genomes can still have burdensome effects! Why do the bacteria keep them around?
(10.4 MB, 11.3 minutes)
B. cereus was grown on urea agar for 6 days at 37 degrees C to induce spore formation.
The endospore stain was done using malachite green as the primary stain and safranin as counter the stain. Malachite green was applied to the smear and set over a steaming water bath for 10 min (stain was no... Read More
Many bacteria have a trick for surviving a water shortage: They dry up like raisins and turn into spores, protecting their essential genetic code. But moisten a spore and it swells right up again.
Those capabilities give bacterial spores some interesting potential as an energy source, as scie... Read More
For the millions of people forced to rely on a plastic tube to eliminate their urine, developing an infection is nearly a 100 percent guarantee after just four weeks. But with the help of a little bubble-blowing, biomedical engineers hope to bring relief to urethras everywhere.
About half of ... Read More
Of all the public transit etiquette violations out there, the sneeze-and-touch at the height of cold and flu season is among the worst. Everyone who rides in a city has seen it: that sickly looking person across the train or bus who sneezes into a free hand then grabs the pole we all share. Rese... Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More
A man is in hospital in Canada with symptoms of a haemorrhagic fever resembling the Ebola virus, a health official has said.
The man had recently returned from Liberia in the west African region, currently suffering a deadly outbreak of an unidentified haemorrhagic fever.
He is in isolatio... Read More
From ocean floors to office desks, bacteria coat nearly every inch of the Earth. Scientists have recently discovered bacteria are present high above the Earth, as well. Ten kilometers up, to be exact, in a region of our atmosphere known as the upper troposphere. In a place where freezing tempera... Read More
