Researchers discover 'acquired' DNA key to certain bacterial infection

...ithout these acquired genes, the bacterium is very inefficient in infecting environmental amoeba, which is the environmental host,” Bermudez said. “In fact, its efficiency is close to zero. But with this ‘island’ of acquired genetic material, the bacterium finds a way to get inside the cells and it takes control...

Genome sequencing reveals key to viable ethanol production

... very tough substance to break down, making for an inefficient process. Wu’s technique may prove much more effective than traditional methods. Instead of using separate steps to break down biomass into glucose and ferment the glucose into ethanol, as is currently done, Wu is working on a way to make a bacteriu...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

...those with the mutations, the drug is likely to be inefficient and possibly harmful, according to researchers at France’s Institut National de la Sante et de la Recherche Medicale (INSERM). "Because a variety of different effective agents may now be available for any given type of cancer, deciding which treat...

New research may overturn conventional wisdom on drug-resistant tuberculosis

...dwide. Most resistance is believed to derive from inefficient treatment, leading to mutations. This study found that 33 of 38 patients had a different strain of TB during treatment than before treatment. Improved methods of preventing TB transmission may be needed in the very facilitie...

Brain regions do not communicate efficiently in adults with autism

...and under abundance of neural connections suggests inefficient and inconsistent communication inside the brains of people with autism and may explain some of the deficits shown by people who have the disorder. The research has practical applications. Murias believes the abnormal patterns of brain activity ...

Researchers create genetically matched embryonic stem cells for transplantation

African wetland managers armed with new technology

... where the lack of updated geo-information and the inefficient in-situ monitoring networks hinder the conservation efforts of wetland managers and water authorities. In support of all African countries participating in the project, GlobWetland ?which is funded by ESA's Data User Element (DUE) ?hosted a five-da...

Natural pine bark extract relieves muscle cramp and pain in athletes and diabetics

..., however studies continue to show magnesium to be inefficient for reducing muscle cramps. "Pycnogenol improves the blood supply to muscle tissue creating a relief effect on muscle cramping and pain. Poor circulation in the muscle is known to cause cramps and Pycnogenol improved the cramping in patients due to ...

New lab technique churns out fungus' potential cancer fighter

...growing more fungus--a time-consuming and terribly inefficient method.Boeckman, the Marshall D. Gates, Jr. Professor of Chemistry at the University of Rochester, has now revealed a process that produces 67 times more rasfonin than any previous method. For the first time, scientists can obtain enough rasfonin to ...

Researchers find molecular 'brake' to cell death

...says, suggesting how current therapy could be both inefficient and lead to resistance in a cell. "Many cancer drugs focus on pushing the mitochondria to release CC, and not on reducing the nucleotide pool, and our new model suggests that decreasing this pool is essential to produce sensitivity in cancer cells t...

A new focus for the mechanism of nerve growth

...," said Forscher. "FSM see that this was caused by inefficient recycling of actin filaments at the back end of the actin network treadmill." Recycling of actin bundles at the ends of structures called filopodia was most strongly affected. This is important because filopodia are thought to play a key sensory ro...

Light activated anticancer drug targeted to DNA using cisplatin like sub-units

...tems had to find the DNA within the cell, an often inefficient process. Now we have added the DNA targeting drug," Brewer said. "We were working on cisplatin analogs before, so we have tied it to light activated systems." Cisplatin begins its interaction with cancer DNA by binding to the nitrogen atoms of the D...

Plants reveal a secret and bring researchers nearer a cleaner future

...ffices is an unaccomplished dream due to the still inefficient technology for a better use of solar energy. The study of photosynthesis in plants could provide new clues by explaining how they absorb almost 100% of the sun-light reaching them, and how they transform it into other forms of energy. Researchers Mi...

Birds and bats sow tropical seeds

...erybody does in (tropical regions) is an extremely inefficient way to maintain and promote species diversity." Howe hopes the project -- which he expects will run for 20 years or more -- will attract additional funding sources. And he predicts close academic collaboration between UNAM and U.S. ecology programs ...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...said Collins. "Existing detoxification methods are inefficient and work only under acidic conductions. Our method can be used over a much broader pH range, including wastewater pH conditions." Fe-TAMLs already have shown promise in killing a simulant of a biological warfare agent (anthrax), reducing fuel pollu...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

...s less indoor pollution than wood, but the current inefficient production method in Africa is one of the most polluting for the global environment and potentially destructive to African forests. The researchers' analysis shows that charcoal can provide comparable health benefits of 1 to 2.8 million avoided death...
