What's breaking now, across thousands of outlets.
A team of researchers from University of Toronto Engineering has created a new type of dye-sensitized nanoparticle that can detect target chemicals at very low concentrations while also distinguishing between molecules with very similar shapes.
We haven't written up this one. Phys.org has the full story — the link below goes straight to it.
Have you ever wondered what Earth observation satellites see when they look down at the deep ocean or a dense tropical forest during the dead of night? The answer, for the most part, is nothing. Standard optical sensors require a steady stream of light to function, and in these photon-limited regions, they hit a hard physical boundary.
Artificial intelligence is transforming how information is generated, processed and stored, but its rapid expansion is also driving unprecedented demand for computing power and electricity. Developing hardware that can process information more efficiently is therefore becoming one of the major technological challenges of the AI era.
Picture yourself in a manufactured colony that orbits between Earth and the moon. It might sound like science fiction, but it's part of a 2019 presentation made by Jeff Bezos, founder of the space…
Spokesperson suggests the unspecified weapons are needed to compete with rivals China and Russia who pose potential threats to US interests in space The post US has weapons deployed in orbit, its…
A new recycling technique could help tackle a major challenge: breaking down some of the toughest plastics without generating large amounts of waste.
Monitoring marine life helps scientists track ecosystem health, improve conservation and manage fisheries. A promising approach is environmental DNA (eDNA), which refers to trace genetic material naturally released into the water by organisms, such as skin cells, mucus and excreta.
