Vera Rubin and Dark Matter
Vera Rubin has been quoted as saying "Does Sex Matter? Of course it does. But does it matter enough to Matter? That's a different question." She is an astronomer and mother of four who successfully combined a serious career with raising a family. She is one of the discoverers of dark matter. [more inside]

have proclaimed the detection of "dark matter" today, but Science News has a more measured take
What we do know is that the Alpha Magnetic Spectrometer
riding aboard the ISS has detected positrons at high energy. Some theorists suggests that dark matter collisions would generate these positrons, but dark matter annihilation should also produce antiprotons, gamma rays and radio waves, which have not yet been observed. Since dark matter
is suspected to account for far more of the universe than ordinary matter, the AMS data is a tantalizing hint of what we might learn.

China: Humiliation and the Olympics
. Orville Schell discusses China's angry reaction
to foreign criticism, the film Dark Matter
(based on the 1991 Lu Gang
shooting in Iowa), and the Beijing Olympics. ... what gives
Dark Matter wider significance is the filmmakers' use of the Iowa incident to explore—indirectly—some important psychological dynamics between China and the West: China's deeply felt sense of historic injury by foreign nations, and the ways its often thwarted efforts to gain acceptance among leading world powers have exacerbated such sentiments. In the past, feelings of injury have arisen from such events as the Opium Wars and the Japanese occupation; and most recently after the Tibetan demonstrations this spring and during the run-up to this summer's Beijing Olympic Games. From the New York Review of Books.

Does dark matter exist?
Dark matter has been suggested as a solution to the galaxy rotation problem
where individual stars don't seem to rotate the way Newton's laws would predict. Now, some scientists are saying that observations fit with Einstein's general relativity, without any dark matter needed. I just find it amazing that no one has tried this yet.

It ain't so dark anymore.
Dark matter seems poised to assume its place among those astronomical phenomena that were predicted to exist before being observed. The planet Neptune
and black holes
to mention two of them. The last 100 years have really been a boom time for astronomy, and they're not slowing down.
