GHOST PARTICLE FROM SHREDDED STAR REVEALS COSMIC PARTICLE ACCELERATOR

Tracing back a ghostly particle to a shredded star, scientists have uncovered a gigantic cosmic particle accelerator. The subatomic particle, called a neutrino, was hurled towards Earth after the doomed star came too close to the supermassive black hole at the center of its home galaxy and was ripped apart by the black hole’s colossal gravity. It is the first particle that can be traced back to such a ‘tidal disruption event’ (TDE) and provides evidence that these little understood cosmic catastrophes can be powerful natural particle accelerators, as the team led by DESY scientist Robert Stein reports in the journal Nature Astronomy. The observations also demonstrate the power of exploring the cosmos via a combination of different ‘messengers’ such as photons (the particles of light) and neutrinos, also known as multi-messenger astronomy.

BINARY STARS ARE ALL AROUND US, NEW MAP OF SOLAR NEIGHBORHOOD SHOWS

The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3-D atlas of widely separated binary stars within about 3,000 light years of Earth—1.3 million of them.

GRAPHENE OXIDE MEMBRANES COULD REDUCE PAPER INDUSTRY ENERGY COSTS

The U.S. pulp and paper industry uses large quantities of water to produce cellulose pulp from trees. The water leaving the pulping process contains a number of organic byproducts and inorganic chemicals. To reuse the water and the chemicals, paper mills rely on steam-fed evaporators that boil up the water and separate it from the chemicals.

RESEARCHERS OBSERVE STATIONARY HAWKING RADIATION IN AN ANALOG BLACK HOLE

Black holes are regions in space where gravity is very strong—so strong that nothing that enters them can escape, including light. Theoretical predictions suggest that there is a radius surrounding black holes known as the event horizon. Once something passes the event horizon, it can no longer escape a black hole, as gravity becomes stronger as it approaches its center.

BACTERIAL MAGNETIC NANOPARTICLES FOR BIOMEDICAL APPLICATIONS

Magnetic nanoparticles biosynthesized by bacteria might soon play an important role in biomedicine and biotechnology. Researchers of the University of Bayreuth have now developed and optimized a process for the isolation and purification of these particles from bacterial cells. In initial tests, magnetosomes showed good biocompatibility when incubated with human cell lines. The results, presented in the journal Acta Biomaterialia, are therefore a promising step toward the biomedical use of magnetosomes in diagnostic imaging techniques or as carrier in magnetic drug delivery applications.

ADVENT OF THE 3-D DIAMOND VALLEYTRONIC TRANSISTOR

DYNAMICS OF NANOPARTICLES USING A NEW ISOLATED LYMPHATIC VESSEL LUMEN PERFUSION SYSTEM

Nanoparticles used in drug delivery systems, bioimaging, and regenerative medicine migrate from tissues to lymphatic vessels after entering the body, so it is necessary to clarify the interaction between nanoparticles and lymphatic vessels. Although technology to observe the flow of nanoparticles through lymphatic vessels in vivo has been developed, there has been no method to evaluate the flow of nanoparticles in a more detailed and quantitative manner ex vivo. Thus, research was conducted to develop an ex vivo lymphatic vessel lumen perfusion system to determine how nanoparticles move in lymphatic vessels and how they affect the physiological movement of lymphatic vessels.
