In their testing, they use a couple of unusual electrode materials, such as a chromium oxide (Cr8O21) and an organic polymer (a sulfurized polyacrylonitrile). Both of these have significant weight advantages over the typical materials used in today’s batteries, although […]

But, of course, you need to make the fuel there in the first place. The obvious choice for that is water, which can be split to produce hydrogen and oxygen. We know there is water on the Moon, but we

Underneath Yellowstone: Two large lobs of hot material from the mantle (in yellow) melt rock closer to the surface (orange), creating pools of hot material (red and orange) that power hydrothermal systems and past eruptions, and may be the sites

One of the two papers published on Wednesday looks at the polarization of the photons in the burst itself, finding that the angle of polarization changes rapidly over the 2.5 milliseconds that FRB 20221022A lasted. The 130-degree rotation that occurred

So, the ultimate goal of the USDA is to eliminate cattle as a reservoir. When the Agency announced it was planning for this program, it noted that there were two candidate vaccines in trials. Until those are validated, it plans

“What we meant by energy efficiency was calculating the energy input and energy output. The energy output was the kinetic energy and the potential energy at the moment of takeoff, defined as the moment when the feet of the robot

We’re nearing the end of the year, and there are typically a flood of announcements regarding quantum computers around now, in part because some companies want to live up to promised schedules. Most of these involve evolutionary improvements on previous

Atom Computing’s system. Rows of atoms are held far enough apart so that a single laser sent across them (green bar) only operates on individual atoms. If the atoms are moved to the interaction zone (red bar), a laser can

By making small adjustments to the frequency that the qubits are operating at, it’s possible to avoid these problems. This can be done when the Heron chip is being calibrated before it’s opened for general use. Separately, the company has

All of which raises questions about what the snowball Earth might have looked like in the continental interiors. A team of US-based geologists think they’ve found some glacial deposits in the form of what are called the Tavakaiv sandstones in
