Dark Matter Gets More Mysterious
A new study has deepened the mystery of dark matter, that evasive substance that keeps entire galaxies together. The standard cosmological model may be wrong as a result.
What's the Latest Development?
A recent study of two far off dwarf galaxies challenges the standard cosmological model by presenting contrary observations of dark energy. Rather than dark matter being concentrated at the center of the Fornax and Sculptor galaxies, as the standard model would predict, researchers at the Harvard-Smithsonian Center for Astrophysics found that it was distributed equally among the millions of stars they observed. "After completing this study, we know less about dark matter than we did before," said the lead author.
What's the Big Idea?
With galaxies like our Milky Way rotating through space at incredible velocities, why don't their stars go flying off in all directions? The answer is dark matter. The gravitational force which keeps our feet on the ground, thanks to Earth's mass, is simply not strong enough to keep entire galaxies together. As a solution, scientists have concluded that another kind of matter, dark matter, keeps stars turning around the center of galaxies. Accordingly, dark matter should be concentrated at their centers.

Research by neuroscientists at MIT's Picower Institute for Learning and Memory helps explain how the brain regulates arousal.
The big day has come: You are taking your road test to get your driver's license. As you start your mom's car with a stern-faced evaluator in the passenger seat, you know you'll need to be alert but not so excited that you make mistakes. Even if you are simultaneously sleep-deprived and full of nervous energy, you need your brain to moderate your level of arousal so that you do your best.
A disturbing interview given by a KGB defector in 1984 describes America of today and outlines four stages of mass brainwashing used by the KGB.
- Bezmenov described this process as "a great brainwashing" which has four basic stages.
- The first stage is called "demoralization" which takes from 15 to 20 years to achieve.
- According to the former KGB agent, that is the minimum number of years it takes to re-educate one generation of students that is normally exposed to the ideology of its country.
When these companies compete, in the current system, the people lose.
- When a company reaches the top of the ladder, they typically kick it away so that others cannot climb up on it. The aim? So that another company can't compete.
- When this phenomenon happens in the pharmaceutical world, companies quickly apply for broad protection of their patents, which can last up to 20 years, and fence off research areas for others. The result of this? They stay at the top of the ladder, at the cost of everyday people benefitting from increased competition.
- Since companies have worked out how to legally game the system, Amin argues we need to get rid of this "one size fits all" system, which treats product innovation the same as product invention. Companies should still receive an incentive for coming up with new products, he says, but not 20 years if the product is the result of "tweaking" an existing one.
