Mystery solved: Melatonin makes these fish sing at night
Their singing isn't very cute, either. (Margaret Marchaterre/Cornell University/Reuters) There are fish that sing. Or drone like a bunch of loud kazoos, anyway. People living in houseboats in the San Francisco Bay have grown used to a low, strange hum that begins suddenly in the dark of the night and stops just as abruptly in the early morning. [Watch this weird little fish walk up waterfalls] The noise comes from male suitors of the species Porichthys notatus, commonly called the plain..>> view originalIf Aliens Call, We Might Not Want To Answer, Says Stephen Hawking
Stephen Hawking has said it before and he’ll say it again: If extraterrestrials call, do not answer ― at least, not without careful consideration. The renowned theoretical physicists hosts “Stephen Hawking’s Favorite Places,” a new short film available on the streaming service Curiosity Stream. The film follows Hawking around the universe as he “travels” in a computer-generated imagery spacecraft, giving the audience a peek into simulations of a black hole and Gliese 832c, an earth-like planet o..>> view originalPluto's 'Heart' Hints at Deep, Underground Ocean
Pluto's heart holds clues about an underwater ocean on the dwarf planet. Credit: NASA/JHUAPL/SwRI A new simulation of how Pluto got its "heart" suggests that the dwarf planet most likely has a deep ocean beneath its surface. Scientists have long suspected that Pluto has liquid water hidden underground. When NASA's New Horizons mission first set sail to the outskirts of the solar system, scientists were already planning to investigate whether the dwarf planet harbors water. When New..>> view originalMorocco Aims for Accord on Financing Climate Change Projects

Credit: US Launch Report The investigation into a dramatic Falcon 9 rocket explosion earlier this month at Cape Canaveral has determined a “large breach” in the launcher’s upper stage helium pressurization system led to the destruction of the booster and its $200 million satellite payload, SpaceX said Friday. Officials said returning to flight “safely and reliably” with the Falcon 9 rocket, a critical vehicle for NASA’s commercial crew and cargo program for the International Space Station, is S..>> view originalBuilding the Space Launch System's core stage
The largest rocket stage in the world is coming together piece by piece at NASA's Michoud Assembly Facility in New Orleans. Large elements for NASA's Space Launch System are in production and will be joined together to create the rocket's 212-foot-tall core stage, the backbone of the SLS rocket. Why is NASA building the world's most powerful rocket? Because SLS is ready to support both near-term missions in the proving ground around the moon starting in 2018, while at the same time being..>> view originalBuzz-worthy proposal: A bumble bee is considered for the endangered list
The past several years have not been kind to the humble bee.But perhaps none suffer more than the rusty patched bumble bee, or Bombus affinis, a fuzzy insect with a rust-colored patch on its abdomen.
