UH Math collaborates with Rice on synthetic gene circuit A long-standing challenge in synthetic biology has been to create gene circuits that behave in predictable and robust ways. Mathematical modeling experts from the University of Houston (UH) collaborated with experimental biologists at Rice University to create a synthetic genetic clock that keeps accurate time across a range of temperatures. The findings were published in a recent issue of the Proceedings of the National Academy of...

Bacteria "plan ahead" by tightening their belts to help them survive looming lean periods, researchers at Cambridge have discovered. At a time when there is growing concern about rising antibiotic resistance, the results – published in the journal PLOS ONE – could lead to new ways of combatting dangerous bacteria. For many years, people thought bacteria worked by simply consuming resources until they ran out, and then entering a stationary, non-growing, phase. Working with physicists...

Scientists have for the first time come closer to understanding how a clone of E. coli, described as the most important of its kind to cause human infections, has spread across the world in a very short time. E. coli clone ST131 is one of the leading causes of urinary tract and blood stream infections and has crossed the globe at a rapid rate. Worryingly, members of this clone are becoming more resistant to antibiotics. As an indication of scale, more than half of all women will suffer a...

Unraveling The Hidden Variation Of Bacteria

Instituto Gulbenkian de Ciencia This news release is available in Portuguese. Our intestines harbor an astronomical number of bacteria, around 100 times the number of cells in our body, known as the gut microbiota. These bacteria belong to thousands of species that co-exist, interact with each other and are key to our health. While it is clear that species imbalances may result in disease, it is unclear at what pace does each species in the gut evolves, a process that contributes to the...

Duke University Bacterial test of a theory has implications for ecology and infectious disease In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it "could do little harm and might provide a touch of home, in addition to a spot of hunting." By the end of the century, the rabbits had begun to overrun native ecosystems, reaching nationwide numbers of 600 million by 1950. They were propagating under a principle known as the Allee...

Epidemic Of E. Coli Infections Traced To One Strain Of Bacteria

George Washington University School of Public Health and Health Services Fast-evolving lethal clone spreads worldwide, according to new study published today In the past decade, a single strain of Escherichia coli, or E. coli, has become the main cause of bacterial infections in women and the elderly by invading the bladder and kidneys, according to a study published today in the American Society for Microbiology's open access journal mBio. Besides becoming more resistant to...

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose fermenting, facultative anaerobic, rod shaped bacterium found in the normal flora of the mouth, skin, and intestines. It is the most important member of the Klebsiella genus of Enterobacteriaceae. It is naturally occurring in soil and about 30% of strains can fix nitrogen in anaerobic conditions. Hans Christian Gram developed the technique now known as Gram staining in 1884 to discriminate between K. pneumoniae and...

Escherichia coli is a Gram-negative rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless; however, some such as O157:H7 can cause food poisoning in humans and are often responsible for product recalls. The normal flora of the gut normally contains the harmless strains and often provide K2 to the body. They are not always confined to the intestine and have the ability to survive briefly outside of the body. It grows easily...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
