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 rise of big data and advances in information technology has serious implications for our ability to deliver sufficient bandwidth to meet the growing demand.
Applications of quantum mechanics are often compromised by the fundamental property of quanta: any measurement inevitably modifies the measured state….

<b>Abstract</b>
Researchers from Goethe University Frankfurt am Main developed a new method to increase proliferation and viability of immune cells, e.g. natural killer (NK) cells, derived from patients or donors. The obtained NK cell preparations are currently tested preclinically for treatment of leukemia.
The research, which was recently published online in the Monthly Notices of the Royal Astronomical Society, shows that more oxygen, carbon and iron atoms exist…

Currently, pillow-plate heat exchangers (PPHE) enjoy growing attention and become increasingly employed in various branches of industry. The ongoing expansion of the PPHE exploitation area generates a need for new structural requirements for this type of equipment. In this regard, the flow configuration in PPHE is crucial for key aspects like energy efficiency, operating costs and functionality. Whereas in conventional PPHE the flow can be redirected by baffles made of welding lines in the inner pillow-plate channels, there is no method to improve the flow configuration in the outer channels.
For this reason, a new PPHE was developed in the group of Professor Kenig at the University of Paderborn, which enables the flow redirection also in the outer channels. A German patent application is pending, international applications are possible. On behalf of the University of Paderborn, PROvendis offer licenses to interested companies.
Nobody is perfect, but sometimes it is the defect that makes the difference. For example, the electric properties of semiconductors undergo significant changes…

The magnetic coupling is capable of transmitting
torque over a hermetically separated distance as a radial magnetic coupling and at smaller dimensions as an axial magnetic coupling. An application might be in a heart catheter pump, where the maximum size is an important and a strong limiting factor.
Sensitive optical components such as semi-conductor laser diodes must be protected from back reflection. A conventional solution to this problem are Faraday optical diodes, which suffer verious problems. We offer a
novel, performant optical diode exploiting spin-orbit coupling of light.
But what if you decide to make changes? You may have to go back, change the design and print the whole thing again, perhaps more than once. So Cornell…
