If confirmed, the new study's hint at a linkage between heart-rate variability and dust-induced inflammation could indicate that "you receive small but constant damage whenever you're exposed," Sastre says.

The new paintings, which recall the balky intensity of early American modernists like Dove and Hartley and hint at the wildness of a German like Nolde, but with a funky touch that's closer to Terry Winters, are close-up views of flowers against nonspecific backgrounds--variations on the theme of a single centered mass more or less filling the square or rectangle.

Running at those extreme energies since June, LEP has recorded four electron-positron collisions whose explosive patterns hint at the fleeting presence of a Higgs particle.

Preliminary data from the DZero detector at Fermilab hint at a similar, though smaller, deviation from theory.

New experimental data, obtained independently at three laboratories, hint at the existence of a type of neutrino with a mass isgnificantly greater than theorists had anticipated.
