Bacteria are abundant in soil, water, and air as well as in the depths of the Earth's crust, organic matter, and live animals or plants. They are also abundantly social -- among themselves and with others. Not only do they interact with each other but also with their host. Bacillus subtilis and Streptomyces coelicolor are two examples from daily life. The former would be involved with the ropiness of spoiled bread. But the well-known Streptomyces produce the soil's earthy aroma and flavor and the majority of today's antibiotics.

Welcome to my universe.. where there is Peace University.
As Fine Scientist, PhD, I write about my interest in various fields, from...
We are aware of the large and small. We can, for example, taste and smell the earthy but invisible Streptomyces coelicolor. This soil-dwelling bacterium might have been in the first rock on Earth. Some estimates mention a time that was almost 3.8 billion years ago.
Here is the Streptomyces coelicolor chromosome as it was mapped by S. D. Bentley et al. in 2002.
Since January 2008, the Gallup-Healthways Well-Being Index surveys 1,000 Americans every day. LIVESCIENCE published today a list in The Well-Being of 50 U.S. States from a study of interviews with over 350,000 individuals. The results are valid for the period between January 2 and December 30, 2008.
Generalizations were also made in the study that well-being (or happiness) was highest in the Mountain and West Coast states, then the Eastern Seaboard followed by the Midwest and Southern states.
Measurements matter in global climate affairs. "IBUKI" is the Greenhouse gases Observing SATellite (GOSAT) that has been circling the Earth since January 23, 2009.
IBUKI ('breath' in Japanese) will assist in precise monitoring of the global atmospheric carbon dioxide concentrations when its observation data sent from space are combined with data obtained on land and used with simulation models. Methane is also observed.

1571 was also interesting. Galileo Galilei was then seven years old. Johannes Kepler was born on December 27. There were two solar eclipses, a total on January 25 and an annular on July 21-22. Four, one partial and three penumbral, lunar eclipses occurred on August 5 and February 10, July 7, and December 31, respectively.
Did someone mention Elvis? This research made the cover of ACS's Journal of Physical Chemistry in color.
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.
