Loud orgies of Mexican fish could deafen dolphins, say scientists
A species of Mexican fish amasses in reproductive orgies so loud they can deafen other sea animals, awed scientists have said, calling for preservation of the "spectacle" threatened by overfishing.
An individual spawning Gulf corvina, say the researchers, utters a mating call resembling “a really loud machine gun” with multiple rapid sound pulses.
And when hundreds of thousands of fish get together to spawn once a year “the collective chorus sounds like a crowd cheering at a stadium or perhaps a really loud beehive”, said study co-author Timothy Rowell from the University of San Diego...
Why must this uniquely successful genre keep enduring slights and insults? After all, snobs dismiss all kinds of pop culture — from hip-hop to sitcoms — but romance novels elicit a special degree of fervent condescension. That denigration fits a larger historical pattern that regards any of the particular interests of women — from midwifery to knitting to “old wives’ tales” — as inferior to the particular interests of men. Are romance novels any more formulaic or unrealistic than the spy novels and thrillers that attract a male readership? Is there any reason — besides stale misogyny — to question the intelligence of romance authors and their fans?
Manhattan has two genetically distinguishable groups of rats: the uptown rats and the downtown rats, separated by the geographic barrier that is midtown.
“If you gave us a rat, we could tell whether it came from the West Village or the East Village,” says Combs. “They’re actually unique little rat neighbors.” And the boundaries of rat neighborhoods can fit surprisingly well with human ones.
Like many nearby stars, Ross 128 has been the target of exoplanet searches for decades. The most sensitive search results previously published were from an analysis of HARPS radial velocity (RV) measurements published in 2013 again with Xavier Bonfils (then with Observatoire de Genève) as the lead author. With only a half dozen measurements available at the time, the star’s RV seemed to vary on the order of a meter per second suggesting that the reflex motion of an exoplanet orbiting Ross 128 was being observed although it was impossible to claim a definitive exoplanet detection or characterize its properties with so little data. With this promising start, additional precision RV measurements were made by the HARPS team over the following years.

Researchers observe sleep-like behavior in jellyfish, a brainless organism :
(T)he revelations about jellyfish sleep are important, he said, because they show how basic sleep is. It appears to be a “conserved” behavior, one that arose relatively early in life’s history and has persisted for millions of years. If the behavior is conserved, then perhaps the biological mechanism is too. Understanding why jellyfish, with their simple nerve nets, need sleep could lead scientists to the function of sleep in humans.

Zika injections shrank aggressive tumours in fully grown mice, yet left other brain cells unscathed.
Human trials are still a way off, but experts believe Zika virus could potentially be injected into the brain at the same time as surgery to remove life-threatening tumours, the Journal of Experimental Medicine reports.

"Take one common jellyfish (Aurelia aurita), submerge it in 96 percent ethanol in a plastic box, stick it in the fridge for a few days, place on a baking sheet at room temperature to let the alcohol evaporate and, voila!, jellyfish chip."
A pair of Apollo-era NASA computers and hundreds of mysterious tape reels have been discovered in a deceased engineer’s basement in Pittsburgh, according to a NASA Office of the Inspector General (OIG) report...
The two computers are so heavy that a crane was likely used to move the machines...
At some point in the early 1970s, an IBM engineer working for NASA at the height of the Space Race took home the computers—and the mysterious tape reels...
"Please tell NASA these items were not stolen," the engineer's heir told the scrap dealer, according to the report. "They belonged to IBM Allegheny Center Pittsburgh, PA 15212. During the 1968-1972 timeframe, IBM was getting rid of the items so [redacted engineer] asked if he could have them and was told he could have them.
