The fiscal year is over. The dying Social, Behavioral, and Economic division of NSF ended up awarding 90 total grants this year, as opposed to ~700-800 in recent past years. Source: grantwitness.org/nsf/analyses...
The graph shows the cumulative number of awards made by month across this fiscal year, as compared to the last 6 fiscal years. The line for this year is total flat until June, but then finally gets up to 91 by October. In prior years the increase starts building earlier and ends on average in the 700-800 range (with variability, last year was only between 400-500).

David Quammen's essay in The New York Times today closes with this paragraph. It's both a scientific falsehood, and an incredibly dangerous narrative. If you're willing to give me five minutes of your time, I'd like to explain why.
The Ebola virus doesn’t need to spill back. It abides in its reservoir host, and awaits its next opportunity. A virus can’t climb out of a bat or a monkey and fly off in search of human prey. It can only spill over. If humans left the reservoir host alone — not hunting it, not capturing it, not eating it, not exporting it live, not disturbing its forest habitat — the virus wouldn’t re-emerge in humans. It would remain where it is, harming no one. But of course that’s not what happens. And when viruses spill, they often spill into us, because the human population is such a big, busy target.

Humaning.
A four-panel comic. In panel 1, a Northern Cardinal and American Goldfinch perch above a busy crowd in a city, looking down. The cardinal says "It's a nice day to go humaning." The goldfinch says "Just look at them. Majestic." In panel 2, a close-up of the two birds. The cardinal says "Nobody tells you that you'll reach a certain age and suddenly get into humaning. I hit 3 years old, and then bam."The birds are looking out over the crowd scene. In panel 3, the cardinal says "Their calls sound funny to us, but each one has a unique meaning." Below, people are saying various things: "I'm tired." "Where's my phone?" "I'd murder a burrito." In panel 4, the birds look down excitedly at a man walking by. The cardinal says "Wait, is that a guy who got dressed in the dark and put his shirt on inside out and backwards?" And the goldfinch exclaims, "Holy... that's a lifer!"
