I've mostly been reading short SF stories recently, most of them from Dangerous Visions.
Here's a few of the ones I've read and enjoyed:
“The Jigsaw Man” by Larry Niven
“The Night That All Time Broke Out” by Brian W. Aldiss
“A Toy for Juliette” by Robert Bloch (although I was surprisingly not a fan of Harlan's continuation)
“The Man Who Went to the Moon — Twice” by Howard Rodman
“Flies” by Robert Silverberg
