The headlines sound thrilling. One might say they bait a click. “ANONYMOUS SAYS NASA HAS EVIDENCE OF ALIEN LIFE. DOES IT?” — Newsweek “The world’s biggest hacking group thinks NASA is about to announce alien life.” — the Independent It’s June 2017 — still early days in a century full of scientific promise and information revolutions. Maybe you know […]

When Jason Nichols joined GE Global Research in 2011, soon after completing postdoctoral work in organic chemistry at the University of California, Berkeley, he anticipated a long career in chemical research. But after four years creating materials and systems to treat industrial wastewater, Nichols moved to the company’s machine-learning lab. This year he began working […]

On any other topic than climate, even the idea of spending so much money for so little, if any, measurable benefit would be laughed out of sight without more ado.

The much touted Paris Climate Accord aims at worldwide reduction of carbon dioxide emissions in order to keep global temperatures from rising more than 2°C above pre-industrial levels. This goal is purely arbitrary and based not upon any physical evidence, but upon the unproven assumption that carbon dioxide emissions play a significant role in global warming. What the Paris Accord really does is to transfer trillions of dollars from industrialized countries, mainly the US, to the sticky-fingered United Nations and to developing nations. It has a very minimal effect on global warming.

Several studies estimate the actual effects of the Accord. The most recent is from Bjorn Lomborg, published in the peer-reviewed journal, Global Policy (read full paper). Here is the paper abstract:

This article investigates the temperature reduction impact of major climate policy proposals implemented by 2030, using the standard MAGICC climate model [developed at the National…

Is science publishing bad for science?

Is science publishing bad for science?

chickeneditorA long and interesting article about science publishing in the Guardian is largely about the history of Robert Maxwells involvement in science publication, but contains much else of interest besides. A few excerpts:

Many scientists also believe that the publishing industry exerts too much influence over what scientists choose to study, which is ultimately bad for science itself. Journals prize new and spectacular results – after all, they are in the business of selling subscriptions – and scientists, knowing exactly what kind of work gets published, align their submissions accordingly. This produces a steady stream of papers, the importance of which is immediately apparent. But it also means that scientists do not have an accurate map of their field of inquiry.

Suddenly, where you published became immensely important. Other editors took a similarly activist approach in the hopes of replicating Cell’s success. Publishers also adopted a metric called “impact factor,” invented in the 1960s by Eugene Garfield, a librarian and linguist, as a rough calculation of how often papers in a given journal are cited in other papers. For publishers, it became a way to rank and advertise the scientific reach of their products. The new-look journals, with their emphasis on big results, shot to the top of these new rankings, and scientists who published in “high-impact” journals were rewarded with jobs and funding. Almost overnight, a new currency of prestige had been created in the scientific world. (Garfield later referred to his creation as “like nuclear energy … a mixed blessing”.)

It is difficult to overstate how much power a journal editor now had to shape a scientist’s career and the direction of science itself.

And so science became a strange co-production between scientists and journal editors, with the former increasingly pursuing discoveries that would impress the latter. These days, given a choice of projects, a scientist will almost always reject both the prosaic work of confirming or disproving past studies, and the decades-long pursuit of a risky “moonshot”, in favour of a middle ground: a topic that is popular with editors and likely to yield regular publications.
