Lonely Bacteria Increase Risk Of Resistance To Antibiotics
2014-04-30 03:29:48

Wellcome Trust Scientists from The University of Manchester have discovered that 'lonely' microbes are more likely to mutate, resulting in higher rates of antibiotic resistance. The study, published today in Nature Communications and jointly funded by The Wellcome Trust and Engineering and Physical Sciences Research Council, explored the mutation rates of E. coli. Researchers found out that the rate of mutation varied according to how many of the bacteria there were. Surprisingly,...

Honey Is The Sweet Solution To Antibiotic Resistance

redOrbit Staff & Wire Reports - Your Universe Online The serious and rapidly growing problem of resistance to antibiotics could have a very sweet solution, according to research presented during the 247th National Meeting of the American Chemical Society (ACS) at the Dallas Convention Center on Sunday. According to Dr. Susan M. Meschwitz, an assistant chemistry professor at Salve Regina University in Rhode Island, and her colleagues, honey – which is sometimes used by medical...

Garlic Substance Can Help Give Antibiotics A Boost When Fighting Resistant Bacteria
2014-02-19 03:57:45

redOrbit Staff & Wire Reports - Your Universe Online A substance found in garlic can help combat even the most aggressive and treatment-resistant strains of bacteria, a doctoral candidate from the University of Copenhagen has discovered as part of a PhD thesis on the beneficial properties of the odoriferous plant and commonly-used culinary ingredient. The discovery, which was made by Faculty of Health and Medical Sciences student Tim Holm Jakobsen, comes as aggressive...

Acinetobacter baumanni, a pathogenic bacterium that is a poster child of deadly hospital acquired infections, is one tough customer. It resists most antibiotics, is seemingly immune to disinfectants, and can survive desiccation with ease. Indeed, the prevalence with which it infects soldiers wounded in Iraq earned it the nickname "Iraqibacter." In the United States, it is the bane of hospitals, opportunistically infecting patients through open wounds, catheters and breathing tubes. Some...

When faced with life-or-death situations, bacteria Рand maybe even human cells Рuse an extremely sophisticated version of "game theory" to consider their options and decide upon the best course of action, scientists reported here today. In a presentation at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, they said microbes "play" a version of the classic "Prisoner's Dilemma" game. Jos̩...

Image 1 - Millions Of Glowing Bacteria Used To Create Living 'Neon Signs'
2011-12-19 10:49:28

[ Watch the Video ] In an example of life imitating art, biologists and bioengineers at UC San Diego have created a living neon sign composed of millions of bacterial cells that periodically fluoresce in unison like blinking light bulbs. Their achievement, detailed in this week's advance online issue of the journal Nature, involved attaching a fluorescent protein to the biological clocks of the bacteria, synchronizing the clocks of the thousands of bacteria within a colony, then...

Those who believe in UFOs (unidentified flying objects) and extraterrestrial life frequently tell us, "We are not alone." We are not, but we do not have to look into space to find company. Our most frequent companions are the billions of bacteria that inhabit us "“ in our gut and genital tract, on our skins, our mucous membranes and elsewhere. Just as we are social creatures, bacteria needs that sense of community to take action. Scientists call this "quorum sensing." Dr. Bonnie...

Bacteria are among the simplest organisms in nature, but many of them can still talk to each other, using a chemical "language" that is critical to the process of infection. Sending and receiving chemical signals allows bacteria to mind their own business when they are scarce and vulnerable, and then mount an attack after they become numerous enough to overwhelm the host's immune system. This system, called "quorum sensing," is an interesting example of sophistication among microbes, says...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
