Lightning is a unique and fascinating phenomenon that has been studied for centuries. Although we now have a better understanding of this naturally occurring spectacle, many of its secrets are yet to be uncovered.
(Phys.org)—Computers are often described with "ones and zeros," referring to their binary nature: each memory element stores data in two states. But there is no fundamental reason why there should be just two. In a new ...
It's well-known that lightning is an electric current—a quick, powerful burst of charge that flows within a cloud or between a cloud and the ground. But surprisingly, scientists still don't fully understand how the initial ...
(Phys.org)—Flash memory—the data storage method often used in phones, computers, and other devices—is continually being miniaturized in order to improve device performance. In an attempt to reduce the short-circuiting ...
(Phys.org) —Today's commercial flash memories usually store data as electric charge in polysilicon layers. Because polysilicon is a single continuous material, defects in the material can interfere with the desired charge ...
(PhysOrg.com) -- Although today flash memory is primarily used as a removable storage medium, it's currently becoming more and more appealing for a wider variety of applications. Moving beyond memory cards and flash drives, ...
(PhysOrg.com) -- The ability to store and retrieve data is an important component of today's computers, as well as other modern electronic devices such as cell phones, video game consoles, and camcorders. Since their invention ...
The first scientific analysis of images taken by NASA's Perseverance rover has now confirmed that Mars' Jezero crater—which today is a dry, wind-eroded depression—was once a quiet lake, fed steadily by a small river some ...

In 5 billion years or so, when the sun has used up the hydrogen in its core, it will inflate and turn into a red giant star. This phase of its life—and that of other stars up to twice its mass—is relatively short compared ...
