While orbiting Saturn for the last six years, NASA’s Cassini spacecraft has kept a close eye on the collisions and disturbances in the gas giant’s rings. They provide the only nearby natural laboratory for scientists to see the processes that must have occurred in our early solar system, as planets and moons coalesced out of [...]

Research of bone cells shows, for the first time, the part of the cells that sense mechanical stimulation and signal the release of bone-growth factors.

To trap and hold tiny microparticles, engineers have “put a ring on it,” using a silicon-based circular resonator to confine particles stably for up to several minutes. The advance could one day lead to the ability to direct, deliver, and store nanoparticles and biomolecules on all-optical chips.

A study conducted at the Montreal Heart Institute has shown unexpectedly that living with children is linked to a reduction in physical activity. Carried out with 756 participants, the study assessed the impact of social networks on exercise, revealing that people with heart disease who live with children exercise less than those people who do [...]
Scientists have constructed molecular “knots” with dimensions of around two nanometers — around 30,000 times smaller than the diameter of a human hair.

Getting angry might help you get your way if you’re negotiating with European-Americans, but watch out — in negotiations with East Asians, getting angry may actually hurt your cause. That’s the conclusion of a new study on how people from different cultures react to anger in negotiations.

By imaging the cell walls of a zinnia leaf down to the nanometer scale, energy researchers have a better idea about how to turn plants into biofuels. A team has used four different imaging techniques to systematically drill down deep into the cells of Zinnia elegans.

Scientists have developed a new way to target viruses which could increase the effectiveness of antiviral drugs. Instead of attacking the virus itself, the method developed at the University of Edinburgh alters the conditions which viruses need to survive and multiply.

The first expedition to search for deep-sea hydrothermal vents along the Mid-Cayman Rise has turned up three distinct types of hydrothermal venting, report marine biologists. The work was conducted to search extreme environments for geologic, biologic, and chemical clues to the origins and evolution of life.
