An international team of astronomers has created a comprehensive three-dimensional map that offers a first look at the weblike large-scale distribution of dark matter in the universe. Dark matter is an invisible form of matter that accounts for most of the universe's mass, but that so far has eluded direct detection, or even a definitive explanation for its makeup.

Scientists are announcing this week their detection of a June 14 gamma-ray burst that probably signals a hitherto undetected type of cosmic explosion. The hybrid gamma-ray burst probably created a new black hole, but the details of how the explosion occurred are unclear.

Carbon nanotubes are tiny garden-hose-like hollow tubes that have considerable promise for future applications such as nano-sized plumbing and nanolithography, and for the creation of numerous tiny devices such as mass sensors and actuators. Such applications require improved understanding of the mechanical properties of carbon nanotubes. Previous studies pointed out that carbon nanotubes behave like macroscopic elastic hoses similar to garden hoses made of rubber.

An international team of physicists, computer scientists, and network engineers led by the California Institute of Technology, CERN, and the University of Michigan and partners at the University of Florida and Vanderbilt, as well as participants from Brazil (Rio de Janeiro State University, UERJ, and the State Universities of São Paulo, USP and UNESP) and Korea (Kyungpook National University, KISTI) joined forces to set new records for sustained data transfer between storage systems during the SuperComputing 2006 (SC06) Bandwidth Challenge (BWC).

Computers and liquids are not very compatible, as many a careless coffee-drinking laptop owner has discovered. But a new breakthrough by researchers at the California Institute of Technology could result in future logic circuits that literally work in a test tube—or even in the human body.

Geologists have uncovered evidence in the oil fields of Oman that explains how Earth could suddenly have changed 540 million years ago to favor the evolution of the single-celled life forms to the multicellular forms we know today.

Research by the California Institute of Technology, the University of Southern California, and Indonesian scientists indicates that within the next few decades another big tsunami could flood densely populated sections of western coastal Sumatra, south of those that suffered from the tsunami of December 2004.

When it comes to digestive ability, termites have few rivals due to the gut activities that allow them to literally digest a two-by-four. But they do not digest wood by themselves—they are dependent on the 200 or so diverse microbial species that call termite guts home and are found nowhere else in nature.

Two and a half billion years ago, when our evolutionary ancestors were little more than a twinkle in a bacterium's plasma membrane, the process known as photosynthesis suddenly gained the ability to release molecular oxygen into Earth's atmosphere, causing one of the largest environmental changes in the history of our planet. The organisms assumed responsible were the cyanobacteria, which are known to have evolved the ability to turn water, carbon dioxide, and sunlight into oxygen and sugar, and are still around today as the blue-green algae and the chloroplasts in all green plants.

In a development that could potentially benefit victims of degenerative neurological diseases, researchers have succeeded in stimulating the growth of adult neural stem cells. Such cells could then be directed towards repairing one's own brain.
