‘Asgardian,’ planong tumira sa outer space, 25 taon mula ngayon
Posted by Michael Lance in category: space
Ayaw mo na ba sa mundo at gusto mo namang manirahan sa kalawakan? Bakit hindi mo subukang maging mamamayan ng tinatawag na “Asgardia”— ang itinatag na space nation na planong bumuo ng “space arks” na magiging tirahan sa kalawakan.

Some science journals that claim to peer review papers do not do so
Posted by Derick Lee in categories: business, economics, science
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 to crack down on fraud in scandal-hit scientific research amid ZTE wrangle
Posted by Derick Lee in category: computing
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.

Implantable 3D-printed organs could be coming sooner than you think
Posted by Klaus Baldauf in categories: 3D printing, biotech/medical
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.

Why the James Webb telescope launch could be the most exciting astrological event of the millennia
Posted by Genevieve Klien in categories: cosmology, space travel
The NASA James Webb telescope could prove to be the biggest leap forward to humankind’s exploration into deep space.
The Webb telescope will give us the ability to investigate the cosmos, unlocking secrets from the beginning of the Big Bang to how galaxies are formed and beyond, bringing us light years ahead of our current understanding of planetary evolution.

Within 4–5 years Made In Space believes their Archinaut space manufacturing robot and manufacturing mini factory will be making large structures like trusses and reflectors in space.
The Archinaut has an industrial-sized 3D printer, cartridges full of plastics and alloys, and robotic arms programmed to assemble the big items extruded by the printer without any human supervision. All Archinaut parts are able to survive in microgravity and harsh conditions like lunar dust storms and extreme temperatures.
