This brings Jupiter’s total number of known moons to a whopping 79 – the most of any planet in our solar system. Twelve new moons orbiting Jupiter have been found – 11 “normal” outer moons, and one that they’re calling an “oddball.” This brings Jupiter’s total number of known moons to a whopping 79 – the most of any planet in our Solar System.

If approved for use in humans, the magnetic wire (depicted in gray) would be inserted into a vein in the arm (in light pink) and attract floating cancer cells labeled with magnetic nanoparticles (light green and gray) that have come from the tumor (neon green). Courtesy of Sam Gambhir

A magnetic wire used to snag scarce and hard-to-capture tumor cells could prove to be a swift and effective tactic for early cancer detection, according to a study by researchers at the Stanford University School of Medicine. The wire, which is threaded into a vein, attracts special magnetic nanoparticles engineered to glom onto tumor cells that may be roaming the bloodstream if you have a tumor somewhere in your body...

Researchers have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface. The technique not only eliminates several manufacturing steps and the associated costs, but also allows any object to sense its environment or be controlled through the application of a high-tech sticker. Eventually, these stickers could also facilitate wireless communication. The researchers demonstrate capabilities on various objects in a paper recently published in the Proceedings of the National Academy of Sciences.

As society moves toward connecting all objects to the internet – even furniture and office supplies – ...

Astronomers find a Famous Exoplanet’s Doppelganger

When it comes to extrasolar planets, appearances can be deceiving. Astronomers have imaged a new planet, and it appears nearly identical to one of the best studied gas-giant planets. But this doppelganger differs in one very important way: its origin. “We have found a gas-giant planet that is a virtual twin of a previously known planet, but it looks like the two objects formed in different ways,” said Trent Dupuy, astronomer at the Gemini Observatory and leader of the study.

Emerging from stellar nurseries of gas and dust, stars are born like kittens in a litter, in bunches and inevitably wandering away from their birthplace...
