To protect from potential terrorist attacks, federal buildings and other critical infrastructures are made with special windows that contain blast-resistant glass. However, the glass is thick and expensive. Currently, researchers are developing and testing a new type of blast-resistant glass that will be thinner, lighter and less vulnerable to small-scale explosions.

The simple picture of star formation calls for giant clouds of gas and dust to collapse inward due to gravity, growing denser and hotter until igniting nuclear fusion. In reality, forces other than gravity also influence the birth of stars. New research shows that cosmic magnetic fields play a more important role in star formation [...]

Bee colonies are well known for high levels of cooperation, but new research demonstrates a conflict for reproduction between worker bees and their queens, leading some workers to selfishly exploit the colony for their own needs. The study focused on Melipona scutellaris — a Brazilian species of highly social stingless bees, found throughout the Atlantic [...]

The Arctic as we know it may soon be a thing of the past, according to the research of a large, international team. The researchers carried out ecosystem-wide studies of the biological response to Arctic warming, and documented a wide range of responses by the plants, birds, animals, insects and humans living there.

Most natural rubber comes from rubber trees in Southeast Asia, but this source is now under threat from a fungus. Researchers have optimized the Russian dandelion to make it suitable for large-scale rubber production.
Fears about the cancer-causing effects of the second most prescribed group of drugs in the Western world have been put to rest, following the largest ever study into their use.
