Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
As a proof of concept, a team led by the University of California San Diego has built a stretchable electronic patch that can be worn on the skin like a…
“We have discovered a supermassive black hole in the center of Fornax UCD3. The black hole mass is 3.5 million that of the Sun, similar to the central black…
When designers select a method for simulating water and waves, they have to choose either fast computation or realistic effects; state-of-the-art methods are…
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year….
Researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and…
Tracker apps provide a means for legitimate personal tracking, i.e. for parents to locate their children. Many tracker apps, however, contain serious security…
From everyday experience we know that metals are good conductors for both electricity and heat — think inductive cooking or electronic devices warming up upon…
The mission to “touch the Sun” is 60 years in the making and will bring a spacecraft carrying a suite of instruments the closest ever before to the Sun with…

However, a new study just published by a research team that includes Arizona State University astrophysicist Michael Line, an assistant professor in ASU's…
These 2-D materials can be prepared in crystalline sheets as thin as a single monolayer, only one or a few atoms thick. Within a monolayer, electrons are…
Heat shields are essentially used as the brakes to stop spacecraft burning up and crashing on entry and re-entry into a planet's atmosphere. This design is the…
What happens when really powerful magnets–capable of producing magnetic fields nearly two million times stronger than Earth's–are applied to materials that…
Scientists are experimenting with narrow strips of graphene, called nanoribbons, in hopes of making cool new electronic devices, but University of California,…
For the past 30 years intense laser cluster interactions have been seen primarily as a way to generate energetic ions and electrons. In surprising contrast…
