Carrying a cup of joe can prove dangerous: Just a small jostle can send hot liquid flying. A latte comes with considerably less risk. Thank the bubbles.Alban Sauret of the French scientific research center CNRS in Aubervilliers and colleagues report...

A subtle attraction between metallic strips could reveal the theorized but never detected particles that impart gravity.An experiment proposed in a Feb. 27 Physical Review Letters paper would explore whether fleeting waves of gravity in a vacuum perceptibly nudge two lead plates together. Detecting this attractive force,...

Using wee balls of iron, scientists can catch radioactive fuel — hook, line and sinker.In liquid, iron nanoparticles quickly lure and encase uranium, which researchers can then reel in with a simple magnet. The method, reported online February 17 in the Journal of the American Chemical Society, could be used to sop up radioactive spills...

The bandwidth for quantum teleportation has doubled. A new technique transfers information about one particle so that another particle takes on two, rather than just one, of the original particle’s quantum properties.Chinese researchers accomplished the feat by nesting one quantum teleportation apparatus inside another. “It’s impressive,” says Wolfgang Tittel, a quantum physicist at the...

View slideshowIn Renaissance Europe, scholars and collectors built curiosity cabinets and filled them with marvels of art and natural history. Catalogs of the contents of these privately held “wonder rooms” were sometimes published to share scientific knowledge, and larger collections formed the basis for museums. Fast-forward to 2013, when chemist...

SAN JOSE, Calif. — Some very old chemistry may provide a new trick for making better batteries.Scientists have developed a strategy that makes sulfur-based batteries much more efficient by exploiting chemical reactions discovered in the 1800s. The research, described February 14 at the annual meeting of the American Association for the Advancement of Science, brings scientists closer to...

Predictions are much easier to make with the benefit of hindsight. Scientists successfully predicted an important quantum property midway through an experiment by analyzing measurements taken before and after. The research, scheduled to appear in the Feb. 13 Physical Review Letters, demonstrates that...

How a violin’s f-holes are shaped can influence the instrument’s lowest notes.MIT scientists, along with a Boston-based violin maker, analyzed how air moves through a violin’s f-shaped holes and through the round, half-moon and C-shaped sound holes of violin ancestors from the 10th to 16th centuries. Air accelerates more quickly through the long, narrow f-shaped holes than through round holes,...
