Positive feedback on the climate from low-level clouds; detecting nuclear blasts anywhere on Earth; mathematical models of society; and more.
How can you weigh a single atom? Researchers have built an exquisite new device that can do just that. It may ultimately allow scientists to study the progress of chemical reactions, molecule by molecule.
By miniaturizing a device that monitors the delivery of healthy cells, researchers are developing a powerful instrument for physicians to use in treating patients with Parkinson’s syndrome, brain tumors and other diseases.
A reduction of as little as 5 percent in fisheries catch could result in as much as 30 percent of the British Columbia coastal ecosystems being protected from overfishing, according to a new study.

Women with cystic fibrosis can have fertility treatment to help them have babies without any long-term adverse effects on either themselves or their children, researchers have found. Women with cystic fibrosis often have thick cervical mucus preventing them from becoming pregnant naturally. However, a pregnancy can be achieved by the use of intrauterine insemination (IUI) [...]

Biochips carrying thousands of DNA fragments are widely used for examining genetic material. Experts would also like to have biochips on which proteins are anchored. This requires a gel layer which can now be produced industrially.
Though digital technologies and high-speed communications have significantly expanded the capabilities of scientists — allowing them to analyze and share vast amounts of data — these technologies are also raising difficult questions for researchers, institutions and journals.
