Waking sleeping plants with plasmas

Commercial crops like grapes, peaches, berries and flower bulbs all go dormant in the winter, essentially sleeping through the seasonal cold before they resume growing, flowering and fruiting again in the warmer months.

A faster, cheaper path to fusion energy

Scientists are working to dramatically speed up the development of fusion energy in an effort to deliver power to the electric grid soon enough to help mitigate impacts of climate change. The arrival of a breakthrough technology—high-temperature ...

Attempting to tame plasmas in fusion

Nuclear fusion, the release of energy when light atomic nuclei merge, is touted as a carbon-free solution to global energy requirements. One potential route to nuclear fusion is inertial confinement. Now a KAUST-led team ...

Extremely small and fast: Laser ignites hot plasma

When light pulses from an extremely powerful laser system are fired onto material samples, the electric field of the light rips the electrons off the atomic nuclei. For fractions of a second, a plasma is created. The electrons ...

Separating the sound from the noise in hot plasma fusion

In the search for abundant clean energy, scientists around the globe look to fusion power, where isotopes of hydrogen combine to form a larger particle, helium, and release large amounts of energy in the process. For fusion ...

Pushing the plasma density limit

For decades, researchers have been exploring ways to replicate on Earth the physical process of fusion that occurs naturally in the sun and other stars. Confined by its own strong gravitational field, the sun's burning plasma ...

Higher plasma densities, more efficient tokamaks

When the density of the hot, ionized gas (known as a plasma) in a tokamak exceeds a certain limit, it usually leads to a rapid loss of heat and plasma currents. The currents are required to confine the plasma. Such events ...

Diamond capsules improve performance of laser fusion

Osaka University-led researchers demonstrated that the perturbation of laser imprinting on a capsule for nuclear fusion fuel made from stiff and heavy materials was mitigated. Using the latest chemical vapor deposition (CVD) ...

Recording the birth of a nanoplasma

An international team of researchers has successfully recorded the birth of a nanoplasma for the first time. In their paper published in the journal Physical Review Letters, the group describes how they pulled off this feat ...
