NASA-funded robotic sub finds bottom of world's deepest sinkhole

...t explored the cenote. It also used the sensors to create maps of the sinkhole’s interior via a technique called simultaneous localization and mapping, or SLAM. Prior to the DEPTHX field experiment, SLAM had been used for navigating in buildings and mines, but had never operated in an underwater environment...

Maggots rid patients of MRSA

...nd the biogun treatment, which uses ionized air to create superoxide radicals and eradicate bacteria. Professor Boulton said: "This is very exciting. We have demonstrated for the first time the potential of larval therapy to eliminate MRSA infection of diabetic foot ulcers. If confirmed in a randomized c...

Traumas like Sept. 11 make brains more reactive to fear

...aumas cause in the brain, the researchers suspect, create vulnerability to developing future mental disorders. Specifically, the Cornell researchers found that three years after Sept. 11, 2001, the amygdalae were most sensitive in those who were close to the World Trade Center. These individuals tended to...

Diminishing dinosaur steps saved by laser and laptop

World's leading scientists announce creation of 'Encyclopedia of Life'

...cedented level. Even five years ago, we could not create such a resource, but advances in technology for se...r the next 10 years, the Encyclopedia of Life will create Internet pages for all 1.8 million species currently named. It will expedite the classification of t...

The longest carbon nanotubes you've ever seen

...searchers were able to break apart hydrocarbons to create a vapor of carbon-atom starting material. Within the vapor sat the new substrate--a catalyst made of alternating metal and ceramic layers atop an oxidized-silicon wafer base--which served as the foundation for growth. "This process is revolutionar...

DOE JGI sets 'gold standard' for metagenomic data analysis

...id was to take known sample genomes, shuffle them, create simulated metagenomes, and use those tools on them, and then we went back and compared the results to the isolate genomes. Essentially, we applied the gold standard's 'the truth' and found there were tools that shouldn't have been used because their...

Researchers attach genes to minichromosomes in maize

...rsity of Missouri-Columbia has discovered a way to create engineered minichromosomes in maize and attach gen...chler said there have been unsuccessful efforts to create artificial chromosomes in plants but this is the first time engineered minichromosomes have been mad...

DNA-damage test could aid drug development

...culture system based on mouse fetal liver cells to create a new system based on adult red cell precursors from mouse bone marrow. Shuga patiently optimized the system, which allows the precursor cells to proliferate and differentiate in the normal way, dividing four or five times before losing their nucleus...

Researchers develop way to calculate speed of bacterial sex

...mediation qualities, bacterial adaptation can also create potentially harmful bacteria that are resistant to antibiotics and increase gene flow from genetically modified organisms to native soils. By developing a real-life model of bacterial gene transfer, UC-Davis researchers hoped to gain insight into the...

Growing nerve cells in 3-D dramatically affects gene expression

Left-right wiring determined by neural communication in the embryonic worm

...w to the midline, communicate with each other, and create a conduit of information that links together these two different sides of the brain." Then, after the gap junctions do their job, they disappear. "This network is transient; we only know about it because we were able to look at this early period." ...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

... more mitochondria, the chemical power plants that create energy in cells. PGC-1alpha is also required for the normal operation of genes that control the development of neuromuscular junctions (NMJ) ?sites on muscle fibers where nerves attach and signal the fibers to contract. Part of the reason that exe...

Brain maps online

...on microscope slides. Those slides were scanned to create image files or "virtual slides," and assembled like tiles into composite images. The maps have a resolution of better than half a micrometer per pixel, or 55,000 dots per inch, with virtual slides approaching 30 gigabytes in size each. ...

Deconstructing brain wiring, one neuron at a time

... to which. The team of Salk researchers sought to create a modified virus whose spread could be limited to a single synaptic connection. "The core idea is to use a virus that is missing a gene required for spreading across synapses but to provide the missing gene by some other means within the initially...

Ultimately, these studies will lay the groundwork for developing new and improved control measures for emerging and reemerging flu viruses.

Stanford-led study closes in on genes that may predispose some people to severe depression

...stead, multiple genes are probably interacting to create what amounts to a genetic baseline level of risk. On top of that baseline, environmental factors are likely mixed in as well, things such as non-genetic physiological problems or psychological traumas. Some 10 to 15 percent of people suffer fr...

Biodiesel study targets cleaner air, cleaner engines
