Bacteria Turns Nasty When Under Threat

Ranjini Raghunath for redOrbit.com - Your Universe Online E. coli is one of millions of bacterial species that live in our gut. From when we are infants, E. coli dwells peacefully in the lower intestine, maintaining a give-and-take relationship with our body – it helps the gut digest food, and gets energy to live and reproduce in return. However, the normally harmless bacterium can quickly evolve into a deadly form that can cause severe food poisoning, infection, and sometimes death....

PrimPol allows cells to make copies of their DNA even when it is damaged, and prevents breaks in the chromosomes Every day, the human body produces new cells to regenerate tissues and repair those that have suffered injury. Each time this happens, the cells make copies of their DNA that they will pass on to the resulting daughter cells. This process of copying the DNA, also called replication, is very delicate, given that it can generate severe alterations in the DNA that are associated...

Bacteria recycle broken DNA that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with resistance to antibiotics in hospitals and in our perception of the evolution of life itself. Our surroundings contain large amounts of strongly fragmented and damaged DNA, which is being degraded. Some of it may be thousands of years old. Laboratory experiments with...

Glowing Plant´s Kickstarter crowdfunding campaign to end on June 7 at 1am EST. San Francisco, CA (PRWEB) June 05, 2013 Glowing Plant is taking the first step towards creating sustainable natural lighting for the planet by using synthetic biology and Genome Compiler´s software to create plants that glow in the dark. That´s right, the team at Glowing Plant is looking to create light without using any electricity, and has looked to crowdfund the entire project on Kickstarter....

Bacterial Transfer Of Resistance Genes Targeted By Scientists
2012-10-24 14:58:18

The bacterium Streptococcus pneumoniae — which can cause pneumonia, meningitis, bacteremia and sepsis — likes to share its antibiotic-defeating weaponry with its neighbors. Individual cells can pass resistance genes to one another through a process called horizontal gene transfer, or by "transformation," the uptake of DNA from the environment. Now researchers report that they can interrupt the cascade of cellular events that allows S. pneumoniae to swap or suck up DNA. The new...

In a new study, Brown University researchers demonstrate a new tool for visually tracking in real-time the transformation of a living population of stem cells into cells of a specific tissue. The “molecular beacons,” which could advance tissue engineering research, light up when certain genes are expressed and don´t interfere with the development or operation of the stem cells. A novel set of custom-designed “molecular beacons” allows scientists to monitor gene...

Caltech researchers measure the rate of DNA transfer from viruses to bacteria Researchers at the California Institute of Technology (Caltech) have been able, for the first time, to watch viruses infecting individual bacteria by transferring their DNA, and to measure the rate at which that transfer occurs. Shedding light on the early stages of infection by this type of virus–a bacteriophage–the scientists have determined that it is the cells targeted for infection, rather than...

The part of bacterial DNA that often carries antibiotic resistance is a master at moving between different types of bacteria and adapting to widely differing bacterial species, shows a study made by a research team at the University of Gothenburg in cooperation with Chalmers University of Technology. The results are published in an article in the scientific journal Nature Communications. More and more bacteria are becoming resistant to our common antibiotics, and to make matters worse, more...

Johns Hopkins scientists have developed a simplified, cheaper, all-purpose method they say can be used by scientists around the globe to more safely turn blood cells into heart cells. The method is virus-free and produces heart cells that beat with nearly 100 percent efficiency, they claim. "We took the recipe for this process from a complex minestrone to a simple miso soup," says Elias Zambidis, M.D., Ph.D., assistant professor of oncology and pediatrics at the Johns Hopkins Institute for...

Ruling Recognizes the Importance of Software Patents WASHINGTON, June 28 /PRNewswire-USNewswire/ -- The Business Software Alliance (BSA) today welcomed the Supreme Court's decision in the closely watched Bilski v. Kappos case. The Supreme Court rejected a federal circuit court's opinion that the so-called "machine-or-transformation" test should be the only test of patentability and reaffirmed the need for patent laws that ensure technological progress in key areas such as software. The...
