Who Should Profit from Yellowstone’s Microbes

The Gold in Yellowstone’s Microbes
…
Yellowstone microbes (and those from a few other hot spots on the planet) may also hold great promise for bioremediation — cleaning up chemical pollution, oil slicks and smokestack emissions — as well as the means to accelerate biomass fermentation and develop drought-resistant crops. And there is more to be discovered: Probably less than one percent of Yellowstone’s microscopic life forms have been discovered and studied.
…
the National Park Service signed a secretive research-sharing agreement with Diversa Corporation in 1998. Non-profit groups quickly cried “bio-piracy!” when they found out and sued the Service over the arrangement. While a federal court dismissed the case, it ordered the Park Service to address the issue… But the Park Service is still trying to come up with an acceptable, benefits-sharing agreement that might allow bio-prospecting of microbes and disclosure of findings, with a fair return to the Park from any commercial success.

Higgs
Posted on November 22, 2007 Comments (2)
Higgs’s theory showed that mass was produced by a new type of field that clings to particles wherever they are, dragging on them and making the heavy. Some particles find the field more sticky than others. Particles of light are oblivious to it. Others have to wade through it like an elephant in tar. So, in theory, particles can weigh nothing, but as soon as they are in the field, they get heavy.
Scientists now know that Higgs’s extraordinary field, or something very similar to it, played a key role in the formation of the universe. Without it, the cosmos would not have exploded into the rich, infinite galaxies we see today. The spinning disc of cosmic dust that collapsed 4.5 billion years ago to form our solar system would never have been. No planets would have formed, nor a sun to warm them. Life would not have stood a chance.
In late summer 1964, two years before he would give his Princeton lecture, Higgs rushed out a succinct letter, packed with mathematical formulae that backed his discovery and sent it to a leading physics journal run from Cern, the European nuclear research organisation in Geneva. The paper was published almost immediately, but went largely unnoticed.

Six Ideas That Will Change the World
Depending upon government regulations, Colvin’s extraction system should go global in as few as five years. Yet ultimately, Colvin, a professor of chemistry and chemical and biomolecular engineering at Rice University, has bigger plans. She sees her method as just the first step toward developing an easy point-of-use water-purification system that would cover virtually every pollutant. The filter would have a dipstick to tell you what’s in the water and a reader to tell you what you need to add to pull it out — perhaps silver nanoparticles to kill bacteria or a protein to capture pesticides.

Moringa Oleifera: The Miracle Tree
Posted on November 20, 2007 Comments (0)
One thing I enjoy brought about by the web is finding interesting tidbits such as – Moringa Oleifera: The Miracle Tree:
The immature pods are the most valued and widely used of all the tree parts. The pods are extremely nutritious, containing all the essential amino acids along with many vitamins and other nutrients. The immature pod can be eaten raw or prepared like green peas or green beans, while the mature pods are usually fried and possess a peanut-like flavor. The pods also yield 38 – 40% of non-drying, edible oil known as Ben Oil. This oil is clear, sweet and odorless, and never becomes rancid. Overall, its nutritional value most closely resembles olive oil. The thickened root is used as a substitute for horseradish although this is now discouraged as it contains alkaloids, especially moriginine, and a bacteriocide, spirochin, both of which can prove fatal following ingestion. The leaves are eaten as greens, in salads, in vegetable curries, as pickles and for seasoning. They can be pounded up and used for scrubbing utensils and for cleaning walls. Leaves and young branches are relished by livestock. The Bark can be used for tanning and also yields a coarse fiber. The flowers, which must be cooked, are eaten either mixed with other foods or fried in batter and have been shown to be rich in potassium and calcium.

Nigersaurus

Structural Extremes in a Cretaceous Dinosaur
This discovery has received a good deal of coverage. Among other things it is great to see this paper is available to everyone who wants to view it because it is published by open access PLoS One. The Nigersaurus was discovered in what is now the Sahara Desert in Niger. When the Nigersaurus was roaming the area, 110 million years ago, the climate was a Mesozoic forest. The dinosaur had a few hundred teeth that were replaced almost monthly (a record). The bones of the head and neck were so minimal and light that the Read more about the Nigersaurus. As the author stated: “One of the stunning things about this animal is how fragile the skull is… Some of the bones are so thin you can shine a light through them.”

Robot Boats Hunt Pirates

Robot Boats Hunt High-Tech Pirates on the High-Speed Seas
For years now, law enforcement agencies across the high seas have proposed robotic boats, or unmanned surface vessels (USVs), as a way to help deal with 21st-Century techno Black Beards. The Navy has tested at least two small, armed USV demonstrators designed to patrol harbors and defend vessels. And both the Navy and the Coast Guard have expressed interest in the Protector, a 30-ft.-long USV built by BAE Systems, Lockheed Martin and Israeli defense firm RAFAEL.
The Protector, which comes mounted with a 7.62mm machine gun, wasn’t originally intended for anti-piracy operations. But according to BAE Systems spokesperson Stephanie Moncada, the robot could easily fill that role.

Cool Crow Research

Very cool project – A Vending Machine for Crows
…
This is the highest-risk segment of the machine’s operation. At this point coins alone are made available whenever the bird lands on the perch. However, should a bird peck or sweep coins off the tray and cause a coin to fall down the funnel, the device then produces some peanuts. This stage is designed to cement in the crows’ mind the relationship between coins going down the funnel and peanuts being made available.
…
Finally we shift the device into its intended, and long-term state of only providing peanuts when coins go down the funnel. Nothing is otherwise provided aside from coins scattered around the device at the beginning of the project.
Joshua Klein Thesis presentation definitely watch this! (the webcast takes like 30 seconds before the talk starts – it is worth the wait). Watch a video from the University of Ithaca site (with Dr. Kevin McGowan).
Other sites that also are mentioned as possible sites: Dr. Anne Clark, University of Binghamton (with a captive population of crows); Dr. Natalie Jeremijenko (seed podcast), Dr. Carolee Caffrey, Harvard and Dr. James Ha, University of Washington. Read the Paper by Joshua Klein about the plans for the experiment.

Disrupting Bacteria Communication
Posted on November 16, 2007 Comments (1)
Princeton scientists break cholera’s lines of communication
The mechanism is a chemical that cholera bacteria use for transmitting messages to each other, known as CAI-1, and has been isolated in the lab of molecular biologist Bonnie Bassler. Her team has shown that the chemical also can be used to disrupt the communication that exists among the bacteria, potentially halting the disease’s progress. The discovery could lead to an entirely new class of antibiotics.
…
Higgins isolated the CAI-1 chemical, which occurs naturally in cholera. Then, Megan Pomianek, a graduate student in the laboratory of Martin Semmelhack, a professor of chemistry at Princeton, determined how to make the molecule in the laboratory. Higgins used this chemical essentially to control cholera’s behavior in lab tests.
The team found that when CAI-1 is absent, cholera bacteria act as pathogens. But when the bacteria detect enough of this chemical, they stop making biofilms and releasing toxins, perceiving that it is time to leave the body instead. “Our findings demonstrate that if you supply CAI-1 to cholera, you can flip their switches to stop the attack,” Higgins said.
Chemist Helen Blackwell of the University of Wisconsin-Madison praised the study, calling it a breakthrough for quorum sensing research, and possibly for medical science.
