Hello. See the giant structure in 2D and also in 3D. The positions of the galaxies in the newly found structure are shown in red in the second and third images. Other galaxies in "blue" are located in front or behind "the Giant." 

To relate to the size of things, consider first the Whirlpool Galaxy for example. This bright galaxy is 23 million light years away and 75,000 light years across.

SB: Richard Leakey, your son, was scheduled to speak at Yale in 2003 on "Wildlife Wars." The announcement mentioned that he and his team, The Hominid Gang, had found more than 200 fossils since Richard took part in his first expedition in 1967. I must apologize for my first name basis here. There are several Leakey names that I would like to bring up.

Leakey: You are a darling! First, my interview occurs on Halloween. Second, you start with Richard, my pride and joy. He is a good boy. He found the "Turkana Boy" in 1984 near Kenya's Lake Turkana -- a complete skeleton. One of the rare finds, you know.

Who on Earth would not like a concrete subject? The Concrete Sustainability Hub (CSH) at MIT studies fundamentals to improve on concrete use. CSH also stands for calcium silicate hydrate, the binder phase of concrete. The Great Dome at MIT, shown below in an architectural draft, contains a "cement liner" on sandstone overlay. This image shows, at the top right corner, the CSH model that was proposed by A realistic molecular model of cement hydrates in Proceedings of the National Academy of Sciences on September 22. Submitted by Roland Pellenq et al. the paper is free online through the PNAS open access option.

Two letters to Nature today burst into data about a gamma-ray burst, GRB 090423. The first is A big gamma-ray burst at a redshift of z approximately 8.2 by N. R. Tanvir et al.
"Climate forcing due to aerosol changes is a wild card," concluded James Hansen, Makiko Sato, Reto Ruedy, Andrew Lacis, and Valdar Oinas in Global warming in the twenty-first century: An alternative scenario. "Current trends, even the sign of the effect, are uncertain. Unless climate forcings by all aerosols are precisely monitored, it will be difficult to define optimum policies."*

Beauty can't hide! Flower gardens exist in our vast oceans. Fishermen have long noted colored fish and coral reefs in the Gulf of Mexico. The flower gardens banks consist of coral-capped banks or sandstone banks with fire coral and sponge-laden pinnacles and flats. Thirteen red dots in the following map locate such banks so close to the northwestern Gulf shores. These coral reefs are the northernmost in the continental United States.
