Occasionally, the sun unleashes powerful flares and coronal mass ejections, which hurl plasma and energetic particles into space. On the infant Earth, this solar activity drove cascades of atmospheric chemical reactions that ...
Fats and oils are essential to life. They provide energy, support the absorption of fat-soluble vitamins, contribute to the structure of cell membranes, and give foods their flavor, texture and mouthfeel. Yet the way fats ...
Canadian companies that disclose their climate-related risks and impacts have a considerable advantage over those that don't when it comes to attracting financing from European institutional investors, according to our recent ...
Inside the cell nucleus, genes must be turned on and off with precision to regulate biological processes. The first models of gene regulation were developed in the 1960s, yet modern science continues to uncover new layers ...
Shielding astronauts from the deadly radiation they face is a central challenge for any designer of a deep-space crewed mission. Even relatively low levels of exposure over long periods can lead to everything from central ...
Oil refining is necessary for transforming raw, unusable crude oil into valuable goods like gasoline, diesel, jet fuel and petrochemical feedstocks. However, the usual distillation process is energy-intensive, spurring researchers ...
Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits.
As visitors peered at skeletons and preserved animals in a London zoological museum during a UK heat wave, staff focused on a different attraction: a computer screen glowing with red and green temperature indicators.
Superconductors have long been considered a promising technology for the energy systems of the future. They can conduct electricity without resistance, thus eliminating both conduction losses and waste heat. Up to now, however, ...
Researchers at the University of Osaka developed a light-driven method for synthesizing Davis reagents that generates the hazardous oxidant mCPBA only on demand and consumes it immediately. Kinetic analysis showed no detectable ...
