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…
In a new paper, Avi Loeb (Harvard-Smithsonian Center for Astrophysics) and Edwin Turner (Princeton University) suggest a new technique for finding aliens: look…
Moreover, its high luminosity indicates that J1823-3021A is the youngest millisecond pulsar found to date, and that its magnetic field is much stronger than…
Pure gamma-ray pulsars are extremely difficult to find despite their high energy because they radiate very few photons per unit of time. Using an improved…
More than two thirds of spiral galaxies, including our own Milky Way, display a central bar that can extend for thousands of light years. These colossal…
In a study designed to pinpoint the source of this and similarly irritating sounds, scientists found that the most obnoxious elements of the noises may be…
The scientists searched for methanol, a key ingredient in the synthesis of organic molecules that could lead to life. Their results have implications for…
Professional safecrackers use a stethoscope to find the correct combination by listening to the clicks of the lock. Researchers at the Ruhr-University Bochum…
Anyone who uses multithreaded computer programs — and that's all of us, as these are the programs that power nearly all software applications including…
A Russian spacecraft carrying the state-of-the-art space tool made by The Hong Kong Polytechnic University (PolyU) is set to embark on a one-year space journey…
But after several thousand years, those barrels will naturally begin to disintegrate due to corrosion. A team of scientists at Argonne National Lab (ANL) in…

The research team discovered that silicon carbide contains crystal imperfections that can be controlled at a quantum mechanical level. The finding is published…
Many modern computer applications use data compression methods like bzip2 or gzip. Those algorithms do not allow the processing of data in its compressed form,…
Because graphene is a two-dimensional material, “all of it is an exposed surface,” says physical chemist Phaedon Avouris, manager of the Nanometer Scale…
After their positions have been pinned down, they are then immediately studied using large ground-based telescopes that can detect the visible-light and…
The two-month test marked the first time engineers evaluated the fully-assembled instrument at its normal operating temperature, a frigid 43 Kelvin (-382° F)….
