Default Poof! Planet-Forming Disk Vanishes Into Thin Air


Quote:
Some 460 light-years away in the constellation Centaurus, a thick disk of dust swirled around a young star named TYC 8241 2652 1, where rocky planets like our own were arising. Then, in less than 2 years, the disk just vanished. That's the unprecedented observation astronomers report in a new study, out today. Even more intriguing: The same thing may have happened in our own solar system.

Poof!

Crazy stuff there. It's incredible that scientists can view the birth process of systems hundreds of light years away. You see the news about the God Particle discovery?

And does the news about the submerged land mass add any credence to the possibility of Atlantis being real?

I don't think enough people are willing to believe there was an advanced civilization. But with all these lost cities being found around the world, it should at least prove that humans have been around and were smarter than we thought much earlier.

I've read briefly about the God particle, I'll have to read it again.. and probably a few more times to really grasp it (if that). I should probably post a link to that in here too..

Default Higgs Boson Particle



Quote:
It was the biggest of Big Science, a $10 billion effort involving 6,000 researchers, a 17-mile circular tunnel deep beneath the border of France and Switzerland, thousands of torpedo-size magnets capable of bending beams of subatomic matter, and trillions of subatomic collisions — all in the quest for a momentary hint, the slightest residual footprint, of an elusive particle called the Higgs boson.

And it worked.
Wednesday’s announcement by scientists in Europe that they’d found the Higgs boson, or something remarkably Higgs-like, was a stunning triumph of both theory and experiment.

Peter Higgs, a theorist who envisioned the particle as a young man in 1964, teared up as he attended the discovery announcement in Geneva.

“It’s really an incredible thing that it’s happened in my lifetime,” Higgs, 83, said when he took the microphone before a packed auditorium at CERN, the European Organization for Nuclear Research, which operates the Higgs-hunting Large Hadron Collider.

The Higgs — famously dubbed “the God particle,” to the chagrin of scientists — is so fundamental to the universe that, in its absence, nothing could exist. The particle is thought to create a sort of force field that permeates the cosmos and imbues other particles with the property known as mass — the resistance to being shoved around.

Should be a very interesting time for physicists going forward from the discovery of the god particle.

This is just me being dumb but when I read about the alternate dimensions, I think of the SciFi type things(tv/books/xmen new class cartoon) where they open up a dimensional portal, walk 10 feet come out of a dimensional portal and then they are across the continent.

If we can avoid a global war or survive it our future looks really awesome.

Default Nasa finds portals

Just heard Joe talking about this on the JRE





Quote:
A favorite theme of science fiction is "the portal"--an extraordinary opening in space or time that connects travelers to distant realms. A good portal is a shortcut, a guide, a door into the unknown. If only they actually existed....

It turns out that they do, sort of, and a NASA-funded researcher at the University of Iowa has figured out how to find them.

"We call them X-points or electron diffusion regions," explains plasma physicist Jack Scudder of the University of Iowa. "They're places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun's atmosphere 93 million miles away."

Observations by NASA's THEMIS spacecraft and Europe's Cluster probes suggest that these magnetic portals open and close dozens of times each day. They're typically located a few tens of thousands of kilometers from Earth where the geomagnetic field meets the onrushing solar wind. Most portals are small and short-lived; others are yawning, vast, and sustained. Tons of energetic particles can flow through the openings, heating Earth's upper atmosphere, sparking geomagnetic storms, and igniting bright polar auroras.

NASA is planning a mission called "MMS," short for Magnetospheric Multiscale Mission, due to launch in 2014, to study the phenomenon. Bristling with energetic particle detectors and magnetic sensors, the four spacecraft of MMS will spread out in Earth's magnetosphere and surround the portals to observe how they work.

Just one problem: Finding them. Magnetic portals are invisible, unstable, and elusive. They open and close without warning "and there are no signposts to guide us in," notes Scudder.

Actually, there are signposts, and Scudder has found them.

Portals form via the process of magnetic reconnection. Mingling lines of magnetic force from the sun and Earth criss-cross and join to create the openings. "X-points" are where the criss-cross takes place. The sudden joining of magnetic fields can propel jets of charged particles from the X-point, creating an "electron diffusion region."

To learn how to pinpoint these events, Scudder looked at data from a space probe that orbited Earth more than 10 years ago.

"In the late 1990s, NASA's Polar spacecraft spent years in Earth's magnetosphere," explains Scudder, "and it encountered many X-points during its mission."

Because Polar carried sensors similar to those of MMS, Scudder decided to see how an X-point looked to Polar. "Using Polar data, we have found five simple combinations of magnetic field and energetic particle measurements that tell us when we've come across an X-point or an electron diffusion region. A single spacecraft, properly instrumented, can make these measurements."

This means that single member of the MMS constellation using the diagnostics can find a portal and alert other members of the constellation. Mission planners long thought that MMS might have to spend a year or so learning to find portals before it could study them. Scudder's work short cuts the process, allowing MMS to get to work without delay.

It's a shortcut worthy of the best portals of fiction, only this time the portals are real. And with the new "signposts" we know how to find them.

Portal NASA

Default Scientists bring 500 million-year-old bacteria back to life



Quote:
A 500 million-year-old bacteria has been brought back to life in a laboratory at Georgia Tech in an experiment with echoes of Jurassic Park's disastrous recreation of the dinosaurs.
The researchers have resurrected a 500-million-year-old gene and inserted it into a modern E Coli bacteria.
The 'Frankenstein' germ has thrived. In the lab, the creation has now lived through 1,000 generations.
The scientists hope to find out whether the 'ancient' bacteria will evolve the same way it did 'first time round' - or whether it will evolve into a different, new organism.
‘This is as close as we can get to rewinding and replaying the molecular tape of life,’ said scientist Betül Kaçar, a NASA astrobiology postdoctoral fellow in Georgia Tech.
The new 'chimeric' bacteria has mutated rapidly - and some have become stronger and healthier than today's germs.
‘The ability to observe an ancient gene in a modern organism as it evolves within a modern cell allows us to see whether the evolutionary trajectory once taken will repeat itself or whether a life will adapt following a different path.’

‘The altered organism wasn’t as healthy or fit as its modern-day version, at least initially,’ said Gaucher, ‘and this created a perfect scenario that would allow the altered organism to adapt and become more fit as it accumulated mutations with each passing day.’

The growth rate eventually increased and, after the first 500 generations, the scientists sequenced the genomes of all eight lineages to determine how the bacteria adapted.

Default Scientists Engineer "Chimera" Primates to Combat Human Ailments





Quote:
Roku, Hex and Chimero are the world’s first primate chimeras—individual monkeys made from multiple fertilized eggs of the same species. Each animal has six different sets of genes instead of one. To produce each monkey, biologist Shoukhrat Mitali*pov and his team at the Oregon Health and Science University placed six separate four-celled embryos into a petri dish and, using a micropipette, nudged them into a single aggregation. After a few days, the researchers implanted the aggregation into an adult female macaque. The resulting young have cells descended from each of six embryos evenly distributed throughout their bodies.

NOW WHAT?
Researchers make chimeras in order to create better models for studying human disease. For example, to study human cancers, scientists produce chimeras to delete or mutate certain cell-growth genes and thus produce mice that develop tumors. But mouse models are only so useful—more than 90 percent of drugs tested in mice in the laboratory fail when used on people. Chimeras, on the other hand, could enable scientists to perform similar mutations and drug research in nonhuman primates, which are biologically closer to humans, and therefore more likely to produce helpful data. One result may be more medical research on primates, though, which raises ethical questions.

Default Ancient Rain Forrest Found Under Miles Of Ice In Antarctica

Quote:
Antarctica has yielded implications about global warming that are chilling.

Drilling deep into the seabed just off Earth's southernmost continent, researchers have discovered remnants of a near-tropical rainforest that existed 50 million years ago.

During this period, known as the early Eocene era, the Earth experienced dramatic greenhouse conditions with high atmospheric carbon dioxide counts and palm trees growing around the South Pole.

Ancient history, right? Not according to an article in this week's issue of Nature, where Antarctic researchers warn that, while the 30 percent growth of our CO2 levels since the Industrial Revolution are still a fraction of the Eocene's, they are projected to see those very same prehistoric greenhouse gas levels within decades, issuing in the start of another Eocene-like epoch.

Looks like it might be time to start passing out sunblock to those penguins.
