Plants may use newly discovered language to communicate
A Virginia Tech scientist has discovered a potentially new form of plant communication, one that allows them to share an extraordinary amount of genetic information with one another.
Harvesting hydrogen fuel from the Sun using Earth-abundant materials
The race is on to optimize solar energy's performance. More efficient silicon photovoltaic panels, dye-sensitized solar cells, concentrated cells and thermodynamic solar plants all pursue the same goal: to ...
Nanotube forests drink water from arid air
(Phys.org) —If you don't want to die of thirst in the desert, be like the beetle. Or have a nanotube cup handy. New research by scientists at Rice University demonstrated that forests of carbon nanotubes ...
How baryon acoustic oscillation reveals the expansion of the universe
Imagine a stadium filled with people. With everyone is in their seats, waiting for the game to begin, there is an undercurrent of noise. A few words between friends, the scuffle of shoes, the creak of a chair. ...
Revving up fluorescence for superfast LEDs: Researchers set speed record for molecular fluorescence
Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal—setting a speed record and making an important step toward realizing superfast light emitting ...
Self-assembling anti-cancer molecules created in minutes
Researchers have developed a simple and versatile method for making artificial anti-cancer molecules that mimic the properties of one of the body's natural defence systems.
Mysterious molecules in space
Over the vast, empty reaches of interstellar space, countless small molecules tumble quietly though the cold vacuum. Forged in the fusion furnaces of ancient stars and ejected into space when those stars ...
Water behavior breakthrough opens a crucial door in chemistry
(Phys.org) —A multi-institutional team has resolved a long-unanswered question about how two of the world's most common substances interact.
Getting more electricity out of solar cells
(Phys.org) —When sunlight shines on today's solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons—behavior ...
Graphene paints a corrosion-free future
The surface of graphene, a one atom thick sheet of carbon, can be randomly decorated with oxygen to create graphene oxide; a form of graphene that could have a significant impact on the chemical, pharmaceutical ...
Single laser stops molecular tumbling motion instantly
In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now Northwestern University scientists have figured out an elegant way to stop a molecule from ...
Familiar yet strange: Water's 'split personality' revealed by computer model
Seemingly ordinary, water has quite puzzling behavior. Why, for example, does ice float when most liquids crystallize into dense solids that sink?
Scientists uncover clues to ATP mystery and how cells work
World's coolest molecules
It's official. Yale physicists have chilled the world's coolest molecules.
