Discovery of neutrino mass earns 2015 physics Nobel
The discovery that subatomic particles called neutrinos have mass has won Takaaki Kajita of the University of Tokyo and Arthur McDonald of Queen’s University in Kingston, Canada, the 2015 Nobel Prize in physics.
- Math
83-year-old math problem solved
An 83-year-old math problem concerning sequences of 1s and –1s has been solved.
- Quantum Physics
Quantum choice can be counterproductive
In a puzzling paradox, delivering quantum messages becomes more difficult if the intended recipient offers the sender multiple options for the time and place of delivery.

William Detmold: Looking deep into atoms’ hearts
MIT theoretical physicist William Detmold probes the fundamental bits of matter that combine to form the nuclei of atoms.
- Physics
Raw chicken, ingenuity make a time-reversal mirror
A new phase-conjugation mirror sends light waves back where they came from, allowing physicists to reconstruct images even if the original light was severely scrambled.
- Physics
Invisibility cloaks slim down
An ultrathin invisibility cloak called a skin cloak offers more stealth in a thinner package.

Short memory can be good strategy
Game theory reveals that there’s a limit to the effectiveness of relying on prior results to predict competitors’ behavior.
- Materials Science
Electron waves refract negatively
Waves of electrons have been bent backward in a sheet of graphene, allowing physicists to focus electrons the way a lens focuses light.
- Materials Science
Graphene shows signs of superconductivity
Ultrathin sheets of carbon can conduct electrical current with no resistance at low temperatures.
- Quantum Physics
New experiment verifies quantum spookiness
A new experiment provides the most robust proof that quantum mechanics doesn’t follow the rules we take for granted in everyday life.

Hawking proposes solution to black hole problem
Light sliding along the boundary of a black hole encodes everything that ever fell inside, suggests Stephen Hawking in a new but incomplete proposal.
