In the past experimentation round Wendelstein 7-X achieved higher temperatures and densities of the plasma, longer pulses and the stellarator world record for the fusion product. Moreover, first confirmation for the optimisation concept on which Wendelstein 7-X is based, was obtained. Wendelstein 7-X at Max Planck Institute for Plasma Physics (IPP) in Greifswald, the world’s largest fusion device of the stellarator type, is investigating the suitability of this concept for application in power plants.

Unlike in the first experimentation phase 2015/16 the plasma vessel of Wendelstein 7-X has been fitted with interior cladding since September last year. The vessel walls are now covered with graphite tiles, thus allowing higher temperatures and longer plasma discharges. With the so-called divertor it is also possible to control the purity and density of the plasma: The divertor tiles follow the twisted contour of the plasma edge in the form of ten broad strips along the wall of the plasma vessel. In this way, they protect particularly the wall areas onto which the particles escaping from the edge of the plasma ring are made to impinge. Along with impurities, the impinging particles are here neutralised and pumped off.

“First experience with the new wall elements are highly positive”, states Professor Dr. Thomas Sunn Pedersen. While by the end of the first campaign pulse lengths of six seconds were being attained, plasmas lasting up to 26 seconds are now being produced. A heating energy of up to 75 megajoules could be fed into the plasma, this being 18 times as much as in the first operation phase without divertor. The heating power could also be increased, this being a prerequisite to high plasma density.

The functional military bases that protect the national security of our country could be under water in just a few years.

Small fluctuations in the universe could explain the origins of man.

Robbert Dijkgraaf explains how competing physics theories might explain why life exists.

Behind all this is a change in the way a lot of journals make their money. Over the past decade, many have stopped selling subscriptions. Instead, they charge authors a publication fee and permit people to read the result for nothing. This “open access” business model has the advantage of increasing the dissemination of knowledge, but it also risks corrupting the knowledge thus disseminated.

WHETHER to get a promotion or merely a foot in the door, academics have long known that they must publish papers, typically the more the better. Tallying scholarly publications to evaluate their authors has been common since the invention of scientific journals in the 17th century. So, too, has the practice of journal editors asking independent, usually anonymous, experts to scrutinise manuscripts and reject those deemed flawed—a quality-control process now known as peer review. Of late, however, this habit of according importance to papers labelled as “peer reviewed” has become something of a gamble. A rising number of journals that claim to review submissions in this way do not bother to do so. Not coincidentally, this seems to be leading some academics to inflate their publication lists with papers that might not pass such scrutiny.

Experts debate how many journals falsely claim to engage in peer review. Cabells, an analytics firm in Texas, has compiled a blacklist of those which it believes are guilty. According to Kathleen Berryman, who is in charge of this list, the firm employs 65 criteria to determine whether a journal should go on it—though she is reluctant to go into details. Cabells’ list now totals around 8,700 journals, up from a bit over 4,000 a year ago. Another list, which grew to around 12,000 journals, was compiled until recently by Jeffrey Beall, a librarian at the University of Colorado. Using Mr Beall’s list, Bo-Christer Björk, an information scientist at the Hanken School of Economics, in Helsinki, estimates that the number of articles published in questionable journals has ballooned from about 53,000 a year in 2010 to more than 400,000 today. He estimates that 6% of academic papers by researchers in America appear in such journals.

China has issued the first national guidelines to enforce academic integrity in scientific research and vowed to punish academics and institutes for misconduct such as plagiarism and fabrication of data.

Researchers and institutes involved in misconduct including plagiarism, fabrication of data and research conclusions, ghostwriting and peer review manipulation will face severe punishments, Xinhua reported.

Scandals involving plagiarism and fabrication of research findings have become more prevalent in recent years. Springer Nature last year retracted 107 papers published in Tumor Biology between 2012 and 2017 after an investigation found the authors had supplied the journal’s editors with made-up contact information for third-party reviewers.

At MBC Biolabs, an incubator for biotech startups in San Francisco’s Dogpatch neighborhood, a team of scientists and interns working for the small startup Prellis Biologics have just taken a big step on the path toward developing viable 3D-printed organs for humans.

The company, which was founded in 2016 by research scientists Melanie Matheu and Noelle Mullin, staked its future (and a small $3 million investment) on a new technology to manufacture capillaries, the one-cell-thick blood vessels that are the pathways which oxygen and nutrients move through to nourish tissues in the body.

In an effort to move away from today’s giant, heavy battle tanks, DARPA’s GXV-T program has been investigating new technologies for fast, agile and smart ground transport. Here are six of the fascinating ideas that were demonstrated last month at Aberdeen Test Center outside Baltimore, Maryland.
