    Cancer bomb zaps tumor cells in mice
    Treatment could have the same effect in humans, scientists say

    LONDON - A smart anti-cancer bomb that acts like a Trojan horse can penetrate deep into tumors where it explodes and destroys cancerous cells without harming healthy ones, scientists said on Wednesday.

    Researchers at the Massachusetts Institute of Technology who devised the molecular size bomb tested it in mice with skin or lung cancer. Mice given the treatment lived more than three times longer than untreated rodents.

    The scientists believe it could have the same effect in humans.

    “We’re quite hopeful and optimistic that as we translate this into humans the results pan out as they have in animals,” Professor Ram Sasisekharan, of MIT’s Biological Engineering Division, said in an interview.

    The smart bomb uses nanotechnology which manipulates materials on a molecular or atomic scale, to deliver chemotherapy drugs to destroy the tumor and anti-angiogenesis agents to block its blood supply.

    sadly it was 60's design, constructed with 70's technology, flown and crashed in the 80's. It was always buffetted by political and military influences while it never had a mission appropriate to its complexity or cost.

    And when it was ultimately given a "raison d'etre" -- the construction of the space station -- it was for something for which itself had no purpose...

    I have read rumors of the probability of another object further out than Pluto for over ten years now.....but now it appears is currently being confirmed:

    Astronomers claim discovery of 10th planet

    An artist's conception shows the possible new planet and its relationship to the sun.

    LOS ANGELES (AP) — Astronomers announced Friday that they have discovered a new planet larger than Pluto in orbit around the sun, likely renewing debate over what exactly is a planet and whether Pluto should keep its status.

    The planet — the farthest-known object in the solar system — is currently 9 billion miles away from the sun, or about three times Pluto's current distance from the sun.

    "This is the first object to be confirmed to be larger than Pluto in the outer solar system," Michael Brown, a planetary scientist at the California Institute of Technology, said in a telephone briefing Friday.

    Brown labeled the object as a 10th planet, but there are scientists who dispute the classification of Pluto as such.

    Astronomers do not know the new planet's exact size, but its brightness shows that it is at least as large as Pluto and could be up to 1 1/2 times bigger. The research was funded by NASA.

    Story continues....

    ‘Monster mice’ are eating island’s seabirds
    Rodents evolved to triple normal size, attack much larger chicks


    JOHANNESBURG, South Africa - “Monster mice” are eating much larger albatross chicks alive, threatening rare bird species on a remote South Atlantic island seen as the world’s most important seabird colony.


    “We think there are about 700,000 mice, which have somehow learned to eat chicks alive,” he said in a statement.

    The researchers believe the mice are devouring more than one million petrel, shearwater and albatross chicks on Gough Island every year.

    The island is home to 99 percent of the world’s Tristan albatross and Atlantic petrel populations — the birds most often attacked. Just 2,000 Tristan albatross pairs remain.


    “The albatross chicks weigh up to 10 kg (22 pounds) and ... the mice weigh just 35 grams; it is like a tabby cat attacking a hippopotamus,” Hilton said.

    The house mice — believed to have made their way to Gough decades ago on sealing and whaling ships — have evolved to about three times their normal size.

    Gattaca is almost a reality now

    A new kind of machine for decoding DNA may help bring costs so low that it would be feasible to decode an individual's DNA for medical reasons. The machine, developed by 454 Life Sciences of Branford, Conn., was used to resequence the genome of a small bacterium in four hours, its scientists report in an article published online today by the journal Nature.

    In 1995, when the same bacterium was first sequenced, by Claire M. Fraser, it required 24,000 separate operations spread over four to six months, she said in an e-mail message.

    The machine uses the chemistry of fireflies to generate a flash of light each time a unit of DNA is correctly analyzed. The flashes from more than a million DNA-containing wells, arrayed on a credit-card-sized plate, are monitored by a light-detecting chip, of the kind used in telescopes to detect the faintest light from distant stars. Then, they are sent to a computer that reconstructs the sequence of the genome.

    The decoding or sequencing of genomes has long depended on a chemical process invented by Frederick Sanger in 1977. But genome centers based on this technology are expensive to equip and operate.

    Before & After: Rare Glimpse at Exploding Star

    01 August 2005

    A star explodes every second or so, somewhere in the universe. It's how they die, and astronomers call the events supernovas.

    While much has been learned over the past few decades, supernovas remain somewhat elusive. Among the trickiest aspects of studying them is to spot a star exploding and figure out what kind of star it was before it fired.

    A new study of Hubble Space Telescope images reveals just the sixth example of a star that was identified before and after it went supernova.

    The problem, in part, is that the vast majority of supernovas that are spotted exist beyond our Milky Way Galaxy. While the supernovas become bright and obvious, it is challenging to resolve images of individual regular stars in other galaxies.

    When a supernova in the Whirlpool galaxy was spotted in late June, plans were made to point Hubble that way. An image of the exploded star was made July 11.

    In a Hubble archive image of the Whirlpool galaxy taken in January, astronomers were able to find the supernova's progenitor star in the same location.

    Astronomers can now say the star was a red supergiant with a mass seven to 10 times that of the Sun.

    ...Weapon-wielding humans, and not warming temperatures, killed off the sloth and other giant mammals that roamed North America during the last Ice Age, a new study suggests.

    The arrival of humans onto the American continent and the great thaw that occurred near the end of the last Ice Age both occurred at roughly the same time, about 11,000 years ago. Until now, scientists were unable to tease apart the two events.

    To get around this problem, David Steadman, a researcher at the University of Florida, used radiocarbon to date fossils from the islands of Cuba and Hispaniola, where humans didn't set foot until more than 6,000 years after their arrival on the American continent.

    The West Indian ground sloth, a mammal that was the size of a modern elephant, also disappeared from the islands around this time.

    "If climate were the major factor driving the extinction of ground sloths, you would expect the extinctions to occur at about the same time on both the islands and the continent since climate change is a global event," Steadman said.

    His findings are detailed in the Aug. 2 issue of the journal for the Proceedings of the National Academy of Sciences.

    This could also explain why more than three-fourths of the large Ice Age mammal species -- including giant wooly mammoths, mastodons, saber-toothed tigers and giant bears -- that roamed many parts of North America became extinct within the span of a few thousand years.

    "It was as dramatic as the extinction of the dinosaurs 65 million years ago," Steadman said...

    Astronauts Notice Flaw During ‘Oceans Eleven’

    The mission of the space shuttle Discovery suffered another setback last night when the shuttle’s onboard DVD player failed to function during an attempt by the astronauts to watch the movie “Oceans 11.”

    Astronauts first suspected that there were problems with the shuttle’s DVD player ten minutes into their viewing of the film, when they noticed that the picture on screen began to skip and then freeze.

    After Commander Eileen Collins contacted mission control to report the problem with the DVD player, NASA personnel advised her to remove the disc, blow on it, and try it again.

    But after reinserting the disc, the problems with the DVD player persisted, leading some at NASA to worry that the astronauts’ entertainment options would be severely limited for the rest of the flight.

    According to one NASA technician who spoke on condition of anonymity, the space agency knew that there were problems with the shuttle’s DVD player prior to the launch but opted to continue with the mission regardless.

    “A bunch of us were saying that it was only a matter of time before that DVD player totally broke,” the technician said. “We were like, you’ve got to equip the ship with a backup DVD player, but no one listened.”

    The technician said that the astronauts could survive the rest of the mission without a working DVD player, but added, “If this were a mission to Mars, this would be a nightmare.”

    Elsewhere, President Bush said today that the theory of “intelligent design” explains the creation of life on Earth but not his Social Security plan.

    Chemist Tries to Solve World's Energy Woes

    By BRIAN BERGSTEIN, AP Technology Writer Sat Aug 6, 7:28 PM ET
    CAMBRIDGE, Mass. -

    A U.S. chemist is trying to determine how the world will produce enough energy to supply 9 billion people by mid-century — and whether that can be done without pumping off-the-charts amounts of carbon dioxide into the air.

    Daniel Nocera, 48, is working to achieve an old, elusive dream: using the bountiful energy in sunlight to split water into its basic components, hydrogen and oxygen. The elements could then be used to supply clean-running fuel cells or new kinds of machinery. Or the energy created from the reaction itself, as atomic bonds are severed and re-formed, might be harnessed and stored.

    There is a beautiful model for this: photosynthesis. Sunlight kickstarts a reaction in which leaves break down water and carbon dioxide and turn them into oxygen and sugar, which plants use for fuel.

    But plants developed this process over billions of years, and even so, it's technically not that efficient. Nocera and other scientists are trying to replicate that — and perhaps improve on it — in decades.

    Hydrogen is the most abundant element in the universe, but it's generally locked up in compounds with other elements. Currently, it is chiefly harvested from fossil fuels, whose use is the main cause of carbon dioxide emissions blamed for global warming.

    And so while hydrogen fuel cells — in which hydrogen and oxygen combine to produce electricity and water — have a green reputation, their long-term promise could be limited unless the hydrogen they consume comes from clean sources.

    That's where Nocera's method comes in. If it works, it would be free of carbon and the epitome of renewable, since it would be powered by the sun. Enough energy from sunlight hits the earth every hour to supply the world for months. The challenge is harnessing it and storing it efficiently, which existing solar technologies do not do...

    ...Nocera had a big breakthrough when he used light to coax multiple hydrogen atoms out of liquid. The key was figuring out the right chemical catalyst...

    ...The achievement, and its revolutionary prospects, won Nocera this year's Italgas Prize, a $100,000 award given annually by an Italian utility to a top energy researcher.

    "Dan is even-money (odds) to solve this problem," says Harry Gray, a renowned California Institute of Technology chemist who was Nocera's graduate adviser.

    But there's a catch. In fact, there's a few, and they illustrate how hard it can be to move alternative energy beyond the proof-of-concept phase.

    Nocera has performed the reaction with acidic solutions, but not water yet.

    The catalyst he used was a compound that included the expensive metal rhodium. To be a practical energy solution, it will have to be made from inexpensive elements like iron, nickel or cobalt.

    Nocera's reaction got the photons in light to free up hydrogen atoms, but that's only half the equation. The harder part will be to also capture the oxygen that emerges when water molecules are split. That way, both elements can be fed into a fuel cell, making the process as efficient as possible....

    Mars Must Share Financial Burden of Space Exploration, NASA Chief Says

    In what was widely seen as a belt-tightening measure, the National Aeronautics and Space Administration said today that it was scrapping all plans for a mission to Mars and would instead wait for Mars to plan a mission to Earth.

    Speaking to reporters at Cape Canaveral, Florida today, NASA chief Michael Griffin said that in the current financial climate, “Rather than sending a rocket to Mars, it makes more sense just to sit and wait for the Martians to come to us.”

    Mr. Griffin said that the space agency came to the conclusion that it would prefer to wait for such a Martian visit after the just-concluded mission of the space shuttle Discovery, which he called “a royal pain from beginning to end.”

    “I say, if the Martians want to deal with foam debris, missing tiles and all of those other headaches, they are more than welcome to them,” the administrator said.

    He also offered harsh criticism for the Martians themselves, saying that they had “failed to pay their fair share of the cost of space exploration.”

    But in an official statement later in the day, the Emperor of Mars rebuffed Mr. Griffin’s demands, saying Mars had “no intention of doing NASA’s work for them.”

    In a parting shot, the Emperor concluded, “And don’t expect Mars to fix Social Security, either, you fool.”

    Elsewhere, after paying Microsoft a seven million dollar settlement for sending millions of spam emails, spam entrepreneur Scott Richter said he was only trying to be his own boss by working from home.

    Catching rays with a Stirling engine

    Stirling Energy Systems is one of a number of start-ups focused on solar power. But there's one key difference: It's using an engine technology first developed in 1816.

    In a Stirling system's power conversion unit the power comes from a cycle of heating and cooling--a gas in the system expands with exposure to an external heat source, such as the sun's rays.

    Astronomers claim discovery of 10th planet
    When I was in 4th Grade (that would be 1972), I clipped an article out of the Detroit News and posted it in the classroom. The headline was something like "Halley's Comet Off Course; 'Planet X' Theory Revived." I wish I'd kept that clipping.

    I do still have clippings from Viking 1's landing on Mars and the Voyager probes' fly-bys of Jupiter and Saturn, as well as the discovery of Pluto's moon Charon.

    I watched the first flight of the space shuttle Columbia in the dormitory room of one of the designers of the mission patch for her final flight. It didn't seem like over 20 years had passed...

    Moon spotted orbiting so-called 10th planet
    Planet nicknamed ‘Xena,’ so moon informally dubbed ‘Gabrielle’

    LOS ANGELES - The astronomers who claim to have discovered the 10th planet in the solar system have another intriguing announcement: It has a moon.


    But the discovery of the moon is not likely to quell debate about what exactly makes a planet. The problem is there is no official definition for a planet and setting standards like size limits potentially invites other objects to take the "planet" label.

    Possessing a moon is not a criteria of planethood since Mercury and Venus are moonless planets. Brown said he expected to find a moon orbiting Xena because many Kuiper Belt objects are paired with moons.

    The newly discovered moon is about 155 miles wide and 60 times fainter than Xena, the farthest-known object in the solar system. It is currently 9 billion miles away from the sun, or about three times Pluto's current distance from the sun.

    Scientists believe Xena's moon was formed when Kuiper Belt objects collided with one another. The Earth's moon formed in a similar way when Earth crashed into an object the size of Mars.

    Scientists capture giant squid on camera

    See video in Full Story Link below:

    TOKYO - When a nearly 20-foot long tentacle was hauled aboard his research ship, Tsunemi Kubodera knew he had something big. Then it began sucking on his hands. But what came next excited him most — hundreds of photos of a purplish-red sea monster doing battle 3,000 feet deep.

    It was a rare giant squid, a creature that until then had eluded observation in the wild.

    Kubodera’s team captured photos of the 26-foot-long beast attacking its bait, then struggling for more than four hours to get free. The squid pulled so hard on the line baited with shrimp that it severed one of its own tentacles.

    “It was quite an experience to feel the still-functioning tentacle on my hand,” Kubodera, a researcher with Japan’s National Science Museum, told The Associated Press. “But the photos were even better.”

    For centuries giant squids, formally called Architeuthis, have been the stuff of legends, appearing in the myths of ancient Greece or attacking a submarine in Jules Verne’s “20,000 Leagues Under the Sea.” But they had never been seen in their natural habitat, only caught in fishing nets or washed ashore dead or dying.

    New biological robots build themselves
    Miniature bots can even correct their own mistakes

    Inspired by biological systems, scientists have developed miniature robots that can self-assemble using parts that float randomly in their environments. The robots also know when something is amiss and can correct their own mistakes.

    Scientists have long been fascinated by how living cells are able to replicate DNA using building blocks floating randomly inside the cell’s nucleus. The interior of the nucleus is filled with a gel-like liquid known as nucleoplasm. The DNA building blocks, known as nucleotides, float around in this liquid like ingredients in a molecular soup. Also present in the nucleoplasm are proteins known as polymerases, which pluck nucleotides from the soup as needed when copying DNA.

    The beauty of this approach is that the parts do not have to be presented in a specific order the way they are in a car assembly line. All the cell has to do is make sure there is a continuous supply of nucleotides and the polymerases do the rest. Furthermore, the more nucleotides present, the more likely they will come into contact with the polymerases and the faster the DNA strand can be assembled.
