Stellarators, twisty machines that house fusion reactions, rely on complex magnetic coils that are challenging to design and build. Now, a physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory ( PPPL ) has developed a mathematical technique to help simplify the design of the coils, making stellarators a potentially more cost-effective facility for producing fusion energy.

“Our main result is that we came up with a new method of identifying the irregular magnetic fields produced by stellarator coils,” said physicist Caoxiang Zhu, lead author of a paper reporting the results in Nuclear Fusion. “This technique can let you know in advance which coil shapes and placements could harm the plasma ’s magnetic confinement, promising a shorter construction time and reduced costs.”

Alien planets with more favorable ocean-circulation patterns might support life in even greater abundance and variety than our own world does, the study determined.

The conversation of humans moving out of this planet and exploring others like Mars for the purposes of finding one that can best support life as the earth does is one we have been hearing for quite a while. And with Elon Musk’s SpaceX and the crazy ambition that this billionaire has in mind, the idea has just been growing over the years to a point of influencing other entrepreneurs to have their own space companies that could make this a reality.

With SpaceX now seeming like the leader in the goal of planning the travel to Mars, Elon has been sure to make it clear that his dream goes beyond just that.

Tissue engineers create artificial organs and tissues that can be used to develop and test new drugs, repair damaged tissue and even replace entire organs in the human body. However, current fabrication methods limit their ability to produce free-form shapes and achieve high cell viability.

Researchers at the Laboratory of Applied Photonics Devices (LAPD), in EPFL’s School of Engineering, working with colleagues from Utrecht University, have come up with an optical technique that takes just a few seconds to sculpt complex tissue shapes in a biocompatible hydrogel containing stem cells. The resulting tissue can then be vascularized by adding endothelial cells.

The team describes this high-resolution printing method in an article appearing in Advanced Materials. The technique will change the way cellular engineering specialists work, allowing them to create a new breed of personalized, functional bioprinted organs.

The Moon is a hot destination right now — especially for NASA, which wants to send people back to the lunar surface, but also for the private space industry. The most ambitious private lunar exploits are still many years off, but already, three companies claim they’ll be putting small robotic landers on the Moon in the next two years, amping up a small space race.

So far, no private entity has landed something successfully on the Moon. Only three government superpowers — the United States, China, and Russia — have ever been able to gently touch down vehicles on the lunar surface, and the Indian government may become the fourth in September. An Israeli nonprofit, SpaceIL, attempted to land the first private spacecraft on the Moon in April, but an early engine shutdown caused the vehicle to crash into the lunar surface instead. That means the door is still open for one of these three companies to make the first private lunar landing.

ME Conferences is organizing “18th International Conference on Gastroenterology and Digestive Disorders” during September 16–17, 2019, Dubai, UAE. Conference highlights the theme- Improving Access in Gastroenterology: From Past to Future.

Gastro Meet 2019 is a leading platform for a focused agenda of the current research in the field of gastroenterology which includes, guest lectures, keynotes, symposiums, workshops, exhibitions, panel discussions, and poster sessions. We invite Gastroenterologists, Hepatologists, General Physicians, Microbiologists, Oncologists, Surgeons, Researchers, Students, and Business delegates to join us at Dubai in August 2018 for the 2-day power packed Gastroenterologists Meet.

The periodic table contains a wide array of elements, numbered from one (hydrogen) to 118 (oganesson), with each number representing the number of protons stored within an atom’s nucleus. Scientists are constantly working to create new elements by cramming more and more protons into nuclei, expanding the periodic table. The effort sparks curiosity and questions: Can the table be enlarged in the opposite direction? Is it possible to make an element zero? Does it already exist?

“Element zero” has been a matter of conjecture for nearly a century, and no scientist searched more ardently for it than German chemist Andreas von Antropoff. It was Antropoff who placed the theoretical element atop a periodic table of his own devising, and it was also he who thought up a prescient name for it: neutronium.

You don’t widely hear Antropoff’’s name today, as his Nazi leanings earned the scientist international disgrace. You do, however, hear about neutronium. Today, the term commonly refers to a gaseous substance composed almost purely of neutrons, found within the tiniest, densest stars known to exist: neutron stars.

If death is in the cards, it may also be in your blood.

Measurements of 14 metabolic substances in blood were pretty good at predicting whether people were likely to die in the next five to 10 years. The data was published this week in Nature Communications.
