Deep within spinach leaves, vibrations enhance efficiency of photosynthesis
Biophysics researchers at the University of Michigan have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion ...
Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
Researchers develop fully photonics-based radar system (Update)
Lawrence Livermore to build super laser for ELI facility in Czech Republic
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Physicists discover atomic clock can simulate quantum magnetism
Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.
A quantum simulator for magnetic materials
Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. ...
New camera system creates high-resolution 3-D images from up to a kilometer away
(Phys.org) —A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the object and measure how long it takes ...
Breaking the final barrier: Room-temperature electrically powered nanolasers
(Phys.org) —A breakthrough in nanolaser technology has been made by Arizona State University researchers.
Disappearing light: Precision measurement of an atomic transition
(Phys.org)—Modern precision measurements are spectacular feats of engineering. An excellent example is determining the passage of time. Before John Harrison's marine chronometer in the mid 18th century, ...
Simulations uncover 'flashy' secrets of merging black holes (w/ Video)
(Phys.org)—According to Einstein, whenever massive objects interact, they produce gravitational waves—distortions in the very fabric of space and time—that ripple outward across the universe at the ...
Nanotube-based terahertz polarizer nears perfection
(PhysOrg.com) -- Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication ...
Insect cyborgs may become first responders, search and monitor hazardous environs
