Wound odors may unlock better traps for flesh-eating New World screwworm

Research on foul odors and open wounds targets flesh-eating insect
The secondary screwworm, pictured here, is related to the New World screwworm. CSU scientists are working to uncover the differences between the two blowflies to better control the New World screwworm. Credit: Anthony Grigsby.

Jessica Metcalf's work stinks. Literally. But the Colorado State University professor's research may be key to protecting livestock and wildlife from a flesh-eating parasite.

Long-lived ytterbium states could sharpen quantum computing and atomic clocks

Long live ytterbium!
Two Yb⁺ ions are held in an ion trap. One of the ions gets pumped into metastable states using a focussed laser beam. The other ion is continuously fluorescing and is used to indicate the presence of the “dark” ion in the metastable state by its off-centred position in the ion trap. The lifetime of the metastable state is measured by recording the time when the dark ion starts fluorescing again. Credit: University of Amsterdam

Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable states and, if so, for how long. The measured long-lived states may find applications in quantum computers and atomic clocks.
