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…
A droplet of clear liquid can bend light, acting as a lens. Now, by exploiting this well-known phenomenon, researchers have developed a new process to create…
Costing less than a cent, the lenses promise a revolution in science and medicine in developing countries and remote areas.
In the quest of understanding how software developers think during programming, an international team of scientists from Germany and the United States observed…
The study, which presents the first viable model for the planetary system orbiting one the first stars discovered to have planets — the star named 55 Cancri…
Working with UW astronomer Eric Agol, doctoral student Ethan Kruse has confirmed the first “self-lensing” binary star system — one in which the mass of the…
Stephen Brooks uses his own custom software tool to fire electron beams into a virtual model of proposed accelerator designs for eRHIC. The goal: Keep the cost…
What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to…
Last month, scientists announced the first hard evidence for cosmic inflation, the process by which the infant universe swelled from microscopic to cosmic size…
Peripheral artery occlusive disease (PAOD) ranks among the most frequent chronic diseases worldwide. Common therapies comprise mechanical interventions, which are not suitable for a considerable number of patients. We offer a new pharmaceutical, achieving an almost healthy blood flow due to an increased growth of collateral vessels. For that immune cells of the patient are used, giving reason to expect a good tolerance and thereby avoiding rejection reactions and the transmission of pathogens.
Graft versus Host Disease (GVHD) is one of the major complications associated with transplantation. It is caused by donor T cells, which recognize the genetically dissimilar recipient and therefore attack the host’s body cells. At present there is no effective therapy available. We offer a simple method, whereby the transplant once is treated ex vivo with a well known substance prior to transplantation. For that only a very low concentration of the substance and a short incubation time are used. Remarkably, GVHD is reduced significantly. Due to the ex vivo treatment no side effects are expected.
But, scientists are continually studying other, less-understood forces that may also shed light on matters not yet uncovered. Among these is quantum…
This is the first time such a pair could be found in an ordinary galaxy. They were discovered because they ripped apart a star when ESA’s space observatory…

This new Hubble image showcases a remarkable variety of objects at different distances from us, extending back over halfway to the edge of the observable…
The team successfully took thermal images of a person through a piece of the new plastic. By contrast, taking a picture taken through the plastic often used…
