A century of cosmic rays

Tue, 01/31/2012 - 08:00
Twenty years after puzzling atmospheric ionization led to the discovery of cosmic rays, their investigation opened up particle physics. Now they’re providing a window on extragalactic astrophysics.

Mikhail Lomonosov and the dawn of Russian science

Tue, 01/31/2012 - 08:00
Curiously unsung in the West, Lomonosov broke ground in physics, chemistry, and astronomy; won acclaim as a poet and historian; and was a key figure of the Russian Enlightenment.

Women in physics: A tale of limits

Tue, 01/31/2012 - 08:00
A newly completed survey of 15 000 physicists worldwide reveals that women physicists still do not have equal access to the career-advancing resources and opportunities enjoyed by their male colleagues.

Optical-fiber microcavities reach angstrom-scale precision

Tue, 01/31/2012 - 08:00
Using heat and light to subtly vary the local radius and refractive index of a glass fiber is a simple and surprisingly reproducible way to create and tune a microresonator.

The Large Hadron Collider yields tantalizing hints of the Higgs boson

Tue, 01/31/2012 - 08:00
There’s not yet enough data for a convincing sighting of standard particle theory’s long-sought capstone. But there’s less and less room for it to hide.

Multiple exciton generation enhances a working solar cell

Tue, 01/31/2012 - 08:00
A single energetic photon can excite more than one electron in a nanocrystal. Collecting those electrons may be a path to higher photovoltaic efficiencies.
