Neutrons investigate tomatoes for insights into interplant chatter

Plants are chatty creatures. In the last decade, researchers have shown plants communicate using underground fungal networks to exchange chemical information. However, exactly how that process works at the microscopic level is not well understood.

New material also reveals new quasiparticles

Researchers have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. This resulted in novel properties of electronic behavior for the crystal as a whole, including so-called Rarita-Schwinger fermions in its interior.

Academics show how to create a spotlight of sound with LEGO-like bricks

Academics have created devices capable of manipulating sound in the same way as light—creating exciting new opportunities in entertainment and public communication.

ATLAS Experiment adds more pieces to the Higgs boson puzzle

The Higgs boson was discovered in 2012 by the ATLAS and CMS Experiments at CERN, but its coupling to other particles remains a puzzle.

Twisting whirlpools of electrons

In Jules Verne's famous classic 20,000 Leagues Under the Sea, the iconic submarine Nautilus disappears into the Moskenstraumen, a massive whirlpool off the coast of Norway. In space, stars spiral around black holes; on Earth, swirling cyclones, tornadoes and dust devils rip across the land.

Experimental device generates electricity from the coldness of the universe

A drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work looks to provide a potential path to generating electricity like solar cells but that can power electronics at night.

Experimental device generates electricity from the coldness of the universe

The obvious drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, which has a frigid temperature, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work, in a recent issue of Applied Physics Letters, looks to provide a potential path to generating electricity like solar cells but that can power electronics at night.

New class of catalysts for energy conversion

Researchers are reporting on a new class of catalysts that is theoretically suitable for universal use.

New all-fiber device simplifies free-space based quantum key distribution

Researchers have developed a simple and stable device to generate the quantum states necessary for quantum key distribution. The device could make it more practical to develop a global data network that uses this very secure method of encryption to protect everything from credit card transactions to texts.

Quantum computing with graphene plasmons

A novel material that consists of a single sheet of carbon atoms could lead to new designs for optical quantum computers. Physicists have shown that tailored graphene structures enable single photons to interact with each other.
