A layered nanoparticle with an anticancer drug core, a gene-silencing inner layer and a tumor-targeting outer layer could provide a new way to attack drug-resistant cancer cells.

Two international teams of astronomers have used the power of the Atacama Large Millimeter/submillimeter Array (ALMA) to focus on jets from the huge black holes at the centres of galaxies and observe how they affect their surroundings. They have respectively obtained the best view yet of the molecular gas around a nearby, quiet black hole and caught an unexpected glimpse of the base of a powerful jet close to a distant black hole.

This colorized mosaic from NASA's Cassini mission shows an infrared view of the Saturn system, backlit by the sun, from July 19, 2013.

A new coating intrinsically conceals its own temperature to thermal cameras.

These color-enhanced scanning electron microscope images show nanosheets resembling tiny rose petals. The nanosheets are key components of a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine. The technology might eventually help to eliminate or reduce the frequency of using pinpricks for diabetes testing.

This diagram shows the orbit of asteroid 2013 TV135 (in blue), which has just a one-in-63,000 chance of impacting Earth. Its risk to Earth will likely be further downgraded as scientists continue their investigations.

This artist's impression shows how photons from the early universe are deflected by the gravitational lensing effect of massive cosmic structures as they travel across the universe.
