Is the staggeringly profitable business of scientific publishing bad for science? | Science | The Guardian

Whatever the fate of Sci-Hub, it seems that frustration with the current system is growing. But history shows that betting against science publishers is a risky move. After all, back in 1988, Maxwell predicted that in the future there would only be a handful of immensely powerful publishing companies left, and that they would ply their trade in an electronic age with no printing costs, leading to almost “pure profit”. That sounds a lot like the world we live in now.

Why carbon dioxide has such outsized influence on Earth’s climate – The Conversation

It shouldn’t be surprising that a small amount of carbon dioxide in the atmosphere can have a big effect. We take pills that are a tiny fraction of our body mass and expect them to affect us.

Today the level of carbon dioxide is higher than at any time in human history. Scientists widely agree that Earth’s average surface temperature has already increased by about 2 F (1 C) since the 1880s, and that human-caused increases in carbon dioxide and other
heat-trapping gases are extremely likely to be responsible.

Without action to control emissions, carbon dioxide might reach 0.1% of the atmosphere by 2100, more than triple the level before the Industrial Revolution. This would be a faster change than transitions in Earth’s past that had huge consequences. Without action, this little sliver of the atmosphere will cause big problems.

The Commuting Principle That Shaped Urban History – CityLab

In 1994, Cesare Marchetti, an Italian physicist, described an idea that has come to be known as the Marchetti Constant. In general, he declared, people have always been willing to commute for about a half-hour, one way, from their homes each day.

This principle has profound implications for urban life. The value of land is governed by its accessibility—which is to say, by the reasonable speed of transport to reach it.

‘Nudging’ Looked Like It Could Help Solve Key Problems in Higher Ed. Now That’s Not So Clear. – The Chronicl e of Higher Education

Now the results of those expansions are in, and they are discouraging. In recent months, a report on the academic-success project said that it hasn’t identified anything that made a difference. Both
financial-aid studies announced null results. So did the effort to nudge more students to apply to selective colleges. Why didn’t these nudges work for a larger population? And where does this leave students finding their way through college — and all of the people trying to help them?
