When a group of nematodes gets together in any kind of liquid, they put on quite a show. Each worm waves its body rhythmically to propel itself along. But the waving isn’t all random—in a dense group of Caenorhabditis elegans, … Continue reading

New class of polyhedra discovered
Geometric forms have fascinated mathematicians since ancient times. Now researchers in California say they have discovered a new class of polyhedron that may already exist in nature and could help lead to novel buildings and other kinds of artificial structures. … Continue reading

Smaller nano-channel weighs with attogram precision
The mass of nanoparticles as small as 10 nanometers in diameter can be determined with attogram precision by measuring the oscillations of a cantilevered nanobeam supporting the particles, researchers report in the Proceedings of the National Academy of Sciences. Furthermore, … Continue reading

The structure of Rubella virus’s outer shell
The protective covering—or nucleocapsid—that Rubella viruses use to sneak into the human body, evade the immune system, and carry out their biological attacks looks nothing like the wrapping of other viruses. Now, for the first time, scientists have determined the … Continue reading

The ants go falling, one by one
For an ant scurrying up a dark, nearly vertical tunnel, one tiny misstep can mean a long tumble down the steep passageway. At least, that’s what happens if the ant doesn’t perform some acrobatic feats to catch himself mid-fall. So … Continue reading
