First, they teleported photons, then atoms and ions. Now one physicist has worked out how to do it with energy, a technique that has profound implications for the future of physics.
A startup that might have a record-breaking solar cell is in danger of going out of business.
A novel manufacturing method could make it practical to stack solar cells and convert more of the energy in sunlight into electricity.
Technology is the primary cause of our skyrocketing health-care costs. It could also be the cure.

Japanese researchers build a gun capable of stopping speakers in mid-sentence.
A 19th-century idea might lead to cleaner cars, larger-scale renewable energy.
As life has evolved, its complexity has increased exponentially, just like Moore’s law. Now geneticists have extrapolated this trend backwards and found that by this measure, life is older than the Earth itself.
Even with a terrible recession and a natural-gas bonanza, the U.S. isn’t cutting emissions fast enough.
If the cosmos is a numerical simulation, there ought to be clues in the spectrum of high energy cosmic rays, say theorists
