Conditions like recurrent miscarriage, preeclampsia, preterm birth and stillbirth are affected by the female’s immune response in ways that the partner’s sperm contribute to.

Sperm are generally viewed as having just one action in reproduction—to fertilize the female’s egg—but studies at the University of Adelaide are overturning that view.

Published in Nature Research journal Communications Biology, new research shows that sperm also deliver signals directly to the female reproductive tissues to increase the chances of conception.

Robinson Research Institute’s Professor Sarah Robertson, who led the project, said: This research is the first to show that the female immune response is persuaded by signals in sperm to allow the male partner to fertilize her eggs and conceive a pregnancy.

Ninety-three days, 4600 miles, and almost 2 million strokes. That’s what it took Chris Bertish to paddle across the Atlantic Ocean on a stand-up paddle (SUP) board.

“It was pretty radical, pretty incredible, driven by a passion and a purpose greater than yourself—and that powered me to get through everything, day in and day out,” said Bertish in a Skype interview with National Geographic.

Beginning off the coast of Morocco, he travelled for 93 days to reach English Harbour, Antigua, where he arrived haggard and grateful to still be standing.

While we’ve seen plenty of runners propose postmarathon (or even, dare we say it, in the middle of a marathon), few have gone the extra mile—or in this case, the extra 100-plus miles—before popping the question.

In a new study from the California Institute of Technology, experts have discovered that fruit flies can fly up to 15 kilometers in a single journey. This distance is the equivalent of the average human traveling over 10000 kilometers, or more than 6200 miles.

The record for the longest distance by a human was set in 2005, when an ultramarathon runner Dean Karnazes ran continuously for 80 hours over 350 miles – roughly 324000 times his body length. The Caltech study has found that fruit flies can travel up to six million times the length of their body.

The experts designed a series of “release and recapture” experiments involving hundreds of thousands of fruit flies under various wind conditions.
