We summarize the week's science breakthroughs every Thursday.
- Materials Science
Invisibility cloaks slim down
A new invisibility cloak offers more stealth in a thinner package.
- 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.
- Physics
Nobel laureate finds beauty in science and science in beauty
In ‘A Beautiful Question,’ Frank Wilczek explores links between math and art
- Materials Science
Graphene shows signs of superconductivity
Ultrathin sheets of carbon can conduct electrical current with no resistance at low temperatures.
- Earth
The magnetic mystery at the center of the Earth
The history of the planet’s all-important magnetic field has scientists ramping up simulations and lab experiments to resolve a baffling paradox.
- Materials Science
Nanogenerators harvest body’s energy to power devices
Nanogenerators offer body-harvested energy to fuel bionic future
- 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.
- Physics
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.
- Humans
Moon bounces, bad spider leaders and more reader feedback
Readers debate faith's role in evolution, compare politicians to spiders and more.
- Physics
3-D printed device cracks cocktail party problem
A plastic disk does what sophisticated computers cannot: solve the cocktail party problem.
- Quantum Physics
Physicists get answers from computer that didn’t run
By exploiting the quirks of quantum mechanics, physicists consistently determined what a quantum computer would have done without actually running the computer.
- Physics
Quest for room-temperature superconductivity warms up
Scientists have demonstrated that a material can conduct electrical current without resistance at temperatures as high as –70° Celsius.
