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…
The new Zeta software platform allows researchers to implement specific imaging workflows for a broad range of applications in drug research very easily. The…

Using the special properties of graphene, a two-dimensional form of carbon that is only one atom thick, a prototype detector is able to see an extraordinarily…
NASA’s Alice ultraviolet (UV) spectrograph aboard the European Space Agency’s Rosetta comet orbiter has delivered its first scientific discoveries. Rosetta, in…
This discovery clarifies the boundaries of our galactic neighborhood and establishes previously unrecognized linkages among various galaxy clusters in the…
However, the timing of the solar cycle is far from precise. Since humans began regularly recording sunspots in the 17th century, the time between successive…
“If you identify an asteroid coming toward us, how you deal with it could depend on its density and structure,” says Dr. Richard S. Miller, a UAH physics…
Keeping upright in a low-gravity environment is not easy, and NASA documents abound with examples of astronauts falling on the lunar surface. Now, a new study…
Chemical reactions drive the mechanisms of life as well as a million other natural processes on earth. These reactions occur at a wide spectrum of…
The physical behaviour of materials is strongly governed by the many electrons which can interact and move inside any solid. While an individual electron is a…
Many a child has forgotten to hold tight to the string of a helium balloon only to have it escape and rise until it disappeared in the glare of the sun. Helium…
The invention provides a novel predictive biomarker to help identify the patient population with the most
favorable clinical outcome to angiogenesis-targeted treatment in mCRC patients. Experiments revealed that patients with low pretherapeutic Ang-2 serum levels
receiving a bevacizumab-containing treatment were associated with a better Response rate compared to patients with high pretherapeutic Ang-2 levels. Additionally to a reduced risk of death (>90%) patients with low pretherapeutic Ang-2 levels showed a
significant increase in progression-free survival (up to five months).
In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story.
Alexander Disease (AxD) is a rare fatal neurodegenerative disorder that is attributed to mutations in glial fubrillary acidic protein (GFAP). Clinically, AxD is considered a type of leukoencephalopathy sometimes characterized by demyelination of the central nervous system (CNS) and the formation of GFAP-containing Rosenthal fibers in astrocytes.
While it has been shown that GFAP mutations cause AxD, the exact pathomechanism is still unknown and there is still no accepted line of treatment.
The present invention provides a new approach for AxD therapy based on the newly indentified role of GFAP in the unconventional secretory pathway (USP).
Playing the part of inspectors, the experts will have access to a wide range of sensor technologies to look for signs of whether a nuclear explosion has taken…
